The Audi inaugurates a new series with a strong car-tempered, intelligent and athletic. With dynamic design, uncompromising quality and technological solutions, the A1 contains all the qualities of the mark in less than four meters. Its presence on the road forward stability, security and strong character. Even the size of the footprint documenting vehicle dynamics: length 3,954 mm, width of 1,740 mm, and height of only 1,417 mm. The wheelbase of 2,469 mm, with consequently reduced overhangs. The arch of the roof, the belt line marked and continuous, strongly sloping rear pillars give the three-port its characteristic silhouette. Audi is known for its ability to transfer models of series the many innovations and ideas presented in his studies, has resumed in the current A1 stylistic elements of the A1 project quattro show car of 2007. Its eye-catching, bold and forward-looking fits smoothly into the language of the forms of the brand.
The front immediately reveals the membership of the Audi family, while presenting innovations in the details. The single-frame radiator grille is the latest result of the evolution of this distinctive stylistic trick. Its gently sloping upper vertices are presented for the first time on the A8 luxury sedan. The air vents with plastic edging effect combined with battens applied horizontally emphasize the sporty image of A1, while the optional fog lamps are placed at the ends of the front side.
The A1 looks determined and focused on the asphalt, like an athlete ready to spring on the starting blocks. The lower lines describe a wave of lights, stands inside them instead wing light - a "wing" - which assumes different features depending on the lighting technology chosen. The highly efficient daytime running lights are standard, as in every Audi. In the xenon plus headlights, the daytime light is generated by two 10 W per LED lamp and irradiated by means of a photoconductive element. The effect is that of a homogeneous luminous band that follows the "wing", immediately above the direction indicator, located at the bottom.
On request it is possible to match the headlight beam of a health care system. The system detects, using a small camera built into the rearview, the oncoming vehicles from the opposite direction and inserted individually, depending on the momentary situation, the high beam or low beam.
A distinctive element: the arch of the roof
A distinctive element that adds a sporty accent to the sides of the A1 is formed by the arc of the roof. On request, Audi offers the arch of the roof in four colors for those who want to create a contrast with the rest of the body. The arc flows into the rear pillar, even more inclined than in many coupe, enhancing the dynamic aspect of the tail of the car, in itself already reported by the presence of the spoiler lip on the edge of the roof. From the optical point of view, the cutting ascending seems almost stretch and projecting forward the shape of the A1. The upper edge of the bonnet is developed in a line that follows the side under the windows and continues until reaching the tail. The so-called tornado line, however, an appearance typical of Audi's trick can also be found in the Audi TT sports, was born at the point where the hood off, touches the front fenders. This sign of puissance and stability of the vehicle proceeding along the door opening to the rear wheel arch. Shadow marked that is created under the tornado line, the muscular body and rounded hips rising dynamic line above the sill are equally characteristic elements of the formal language of the brand. The same applies to the relation of 2/3 to 1/3 between the metal surfaces and the glazing of the passenger compartment. The outside mirrors are applied directly on the doors, as in the TT and R8 and the handles are made of thick style. The wheel arches painted with wise harmony can accommodate a maximum wheel diameter of 18 ". Another innovative solution in the compact class is represented by the back entirely dominated by the boot lid. The hood from the labeled form creates an aerodynamic edge above the support plate. Below it sculpturally integrated into the design of the car back from the optical drives and monolithic wedge shape as the front ones.
The backlight is even and unusually extensive, even in the basic version. The xenon plus version or as a single option, in each of the rear lights are set 54 LEDs, with a total power consumption of only 3.5 watts. The so-called light-emitting LED SuperRed particularly intense ruby red, creating a seemingly three-dimensional lighting effect through the clever juxtaposition of two curved lines. The appearance of the stop lamps, strengthened by the presence of reflectors, is circulated for the presence of two chrome bezels. The fog is integrated into the light and stop using the LED variable light intensity. A demonstration of the special attention paid to detail by Audi designers is represented by additional LED inserted in the rear pillars. Since the boot lid open is impossible to distinguish the taillights, the signaling function of the position of the car is taken from the LEDs. the apron a black diffuser-style racing completes the underside of the tail giving it a sporty touch. The tailpipe double conformation in 1.4 TFSI displays on the bottom left and adorned with elegant masks in the Ambition line. The exhaust system as a whole is very light, as the use of stainless steel quality has reduced the thickness of the walls of the tubes and the sound-absorbing elements. The A1 is available in ten colors. The standard colors are White Amalfi, the Blue Cloud and Black Diamond; metallic colors are Ice Silver, Deep Black, Brown Teak, Rosso Shiraz, Scuba Blue, Misano Red and Grey Astro.
Something for everyone: the configuration of the exterior
Addition to the choice of body colors, the Audi offers many possibilities to customize the car. There are a total of 800 different ways to configure the exterior, including adhesive films to decorate the arch of the roof. The body of the mirrors can be painted in body color or in the arc of the roof. The aerodynamic kit Competition, which will be introduced on the market at a later time, includes an increase for the front spoiler, redesigned sills, a rear diffuser and matte chrome sport tailpipe. The package can be completed with a wing mounted on the roof. Quattro GmbH has other options for the characterization of Serbia's A1 sports, such as tinted rear windows. Look in the packet frames of black single-frame grille, fog lights, license plate and the grid itself feature a black matte or glossy. The S line exterior package includes bumper instead reworked form and modifications to the radiator grille, the front spoiler, air intakes, insert the speaker, the sills and tailpipes. The package also provides a marked spoiler on the roof and the S line written on the front fenders and on access strips.
The Body
As with any Audi, the body of the A1 is essential for the quality of the medium, and precise dell'handling sports, driving comfort and safety. Two-thirds it is composed of high and very high strength steels of different classes. Fundamental, first of all, the steels formed hot. The plates are brought to an extremely high temperature in the oven and immediately after molded in a mold cooled water. It is the change in temperature to confer on them an extreme tensile strength. The hot-formed steels account for 11% of the body. Are used in the cockpit, in the rear parts of the side members, in the center pillars and in the casing of the roof, that is to say where it is particularly important that the components have extreme resistance and at the same weight. The use of high and very high strength steels is the basis of body weight, which amounts to just 221 kg. From the combination of the high resistance to torsion, the structural conformation of the body and the low weight is obtained a value of lightweight construction very good.
Another factor that contributes to increase the rigidity of the body is the particular method of connection of its elements implemented in the new production facility in Brussels. In each automobile is 66 meters of special glue applied, some with optical monitoring procedures. The glue has the important function of joining the pieces and, simultaneously, to seal the joints, to the benefit of the total weight, considering that in many situations it is possible to renounce the use of agents sealants. The high structural rigidity has positive implications on acoustics inside the car, completely free of annoying rumble. Audi's developers have meticulously analyzed the propagation of the sound field emitted from the wreckage, then going to reinforce in the targeting of high stress areas while driving the vehicle. A set of light absorbing materials make the internal acoustic comfort comparable to that of the premium class. Also with regard to occupant safety, the A1 is at the top of the class. In the case of the left half front, the impact energy is conveyed to the opposite side of the vehicle, in order to reduce the stresses to which they are exposed to the occupants. The pillars, the wall that separates the engine compartment from the passenger footwell and the rear parts of the side members provide a particularly high protection due to their extreme hardness. Four acceleration sensors and provide pressure to the control unit of the airbag all the signals needed to detect the magnitude of the impact. The standard A1 is equipped with two front airbags, side airbags integrated in the front seat backs and large head airbags. The security system is complete with belt latch tensioners, belt force limiters for integral head restraints and the facility goes into action in case of collision. Isofix attachments for child seats in the rear seats are fitted as standard. The instrumentation informs the driver about the status of all the belts of the passenger compartment.
Regarding the safety of pedestrians in case of investment, standards of Audi surpass the requirements of the law. The front bumper cross member behind the bumper and bonnet meet all the criteria most important. The bonnet is coupled to the bodywork by means of two closures, a solution that makes it very hard despite its low weight. Moreover, the collision occurred at low speed have particularly serious consequences on the medium. The elements of the damaged bumpers can be replaced individually. The cross front crumple box and placed forward of the side members are made of aluminum. They constitute a unitary casing which has the aim to protect both expensive components such as the radiator and the air conditioning system, both the welded structure of the bodywork.
Refined to the extreme: the aerodynamics
with a drag coefficient of 0.32 in the basic version and a frontal area of 2.04 m2, A1 is one of the top class. The accurate aerodynamics is the result of countless measures for improvement and adjustments in the wind tunnel in Ingolstadt. During the design of the car, the coefficient of aerodynamic resistance was reduced by 0.08 units. This results in a lowering of the fuel consumption of 0.6 liters per 100 kilometers. The body has been the subject of laborious improvements in every detail, from the wheels to the corners near the taillights and the triangular brackets that connect the roof spoiler to the car body. Devices are simple and that the outer appearance, however, help to improve the aerodynamics of the car, consistently increasing stability.
The floor is covered almost entirely by a plastic coating that offers protection from salt and stones, and optimizes the airflow under the car. Even in this context, the Audi engineers devoted particular attention to detail, by applying the spoiler even before the wheels and even in the cavity that houses the spare wheel. The platform designed so reduces the CX value of about 10%. The area surrounding the single-frame is completely sealed, so that all incoming air can get to the radiator without creating turbulence. The radiator fan controlled continuously variable helps to strengthen the efficiency of this construction solution. The A1 glides silently in the wind, thanks to enormous efforts to design and optimization in a wind tunnel. Even the gaskets, crystals and many other details of form combine to improve aerodynamics. The exterior rear-view, thanks to the grooves and the edges accentuated, they also have the function of limiting the fouling of the side, of the side windows and the mirror with the same wet roads.
The interior
Sportiness and precision are the hallmarks of the interior of the A1. The designers have often found inspiration from engineering and aeronautical construction techniques related to it lightly. The instrument panel is elegantly curved, reveals related issues under the wing of a plane, and its horizontal bevel expresses the perfect balance between lightness and solidity. On the front edge are four circular air vents and very pronounced, which recall the features of a jet turbine. Their position can be adjusted by means of a singular kinematic ball.
The center console appears to float above the center tunnel without contact with the dashboard. The center console, while vertical is slightly leaning towards the driver. The bottom houses the secondary switches and climate controls. Audi offers a series of heating and ventilation, and air conditioning, a manual or automatic, and only available as an option. The air conditioner also evaluates the position of the sun and humidity. A special highlight aesthetic and tactile is represented by the three adjustment knobs from finely ribbed cylindrical shape, with their functioning also emphasized by precise click to rotation.
Unparalleled:
The center stack houses controls for the radio or the optional MMI infotainment. The board display with a diagonal of 6.5 ", available as standard with the staging concert radio, is built completely within the dashboard. By a simple touch protrudes from its seat to move mechanically, with a movement elegant and uniform, in a vertical position easy to read. The removable display is unmatched in the compact class. The A1 is equipped as standard with a sporty three-spoke steering wheel. On request can be finely coated leather with velor inserts from chrome look. The construction above implies a multifunction steering wheel with optional rocker shifter if the car also mounts changing high-tech S tronic. large circular instruments, light and elegant, white numerals and red needles exhibit on black background. The commands are arranged in a rational and ergonomic and allows a clear and intuitive control in classic Audi style. At night the instruments are illuminated white and red buttons. The interior lighting in LED technology is another unique solution for this segment. The light emitting diode of white color, quality and efficient, are used both for the mood lighting in the doors and roof module, both for the interior light, the reading light and for the illumination of the footwell, the area access and the vanity mirror. The LED lighting technology is part of the package set up Media Style, but it can also be ordered separately. If A1 is equipped with the BOSE Surround Sound, also borders on the door midrange speakers are indirectly illuminated with white light, creating a very suggestive.
Another item of equipment is the top driver information system, available as an option in the line of construction Attraction, Ambition, or serial line. Its function is to present all the important information related to audio sources, on the phone to the vehicle and the optional navigation system on a monochrome screen positioned between the circular instruments. The modern control system solution, with a tabbed view and freely programmable shortcut key, makes use simple and intuitive. The command can also take place via the buttons and the wheels of the optional multifunction steering wheel, as in the Audi models to a higher category. The system is always included in the package MMI Navigation plus. The information system for the driver has an integrated on-board computer with efficiency program that assists the driver by providing recommendations for an optimal gear shift. A magnified view of the directions of travel indicates the time when it would be appropriate to engage a separate report. Another feature shows which users are active on the electric car (eg. Air conditioner or rear window) and how much fuel they consume.
A tightly fitting the seats in the A1
A1 The seats offer excellent grip and support for maximum comfort of the occupants of all sizes. Standard driver's seat is height adjustable. The Ambition line includes sport seats with lumbar support and the possibility of mass-height adjustment for the front passenger seat. Even easier access to rear seats "easy entry" is standard with the Ambition setting. The rear seats are shaped according to the posture of occupants, and their head restraints can be lowered so as not to obstruct the view from the rear view mirror. All places have many extra items. The center console has space for two cupholders, a spacious tub and a 12 V, while the doors and rear trim panels feature large pockets. In the basic version, the place on the board dedicated to the display board is occupied instead by a drawer with hinged door.
On request, Audi offers a height-adjustable center armrest and a pocket. The storage package is optional, provides multiple latches in the rear, a front lockable drawer, a drawer under the front seat tilting left, two pockets behind the front seat backrests, a net in the front passenger and three tray with cup holders for the rear seats.
Prestigious and glamorous: the choice of materials
The premium character of the car is realized in all the interior details. The choice of materials, workmanship and execution in their care, and even of all the joints was not made any concessions with respect to larger models. The surface of the dashboard is soft to the touch and adorned with elegant ribs, all the buttons and knobs are all included in their homes without games and move with uniform regularity, also the lever of the engine hood is operated with surprising precision of movement. In the course of construction Ambition, Attraction and an optional in-line, many elements are in aluminum look, including the access strip, the climate control knobs, the knob of the lights and the handle of the drawer front. Furthermore, the crown of the three-spoke sports steering wheel, handbrake grip and gearshift lever are covered in leather and adorned with simple moldings made of aluminum.
Each line of equipment is distinguished by the choice of materials. The Attraction line of the seat covers are blacks or gray titanium, as well as the center console, the armrests, the document pockets and speaker grilles. The sports seats bichromatic line Ambition adopt the titanium gray or green Wasabi as contrasting color to black. It is also available all black upholstery. The package Media Style provides, alternatively, the beige color velvet. The optional leather upholstery can be ordered both in Milan this line, both in the Ambition line in three different colors and combinations. The center console and door armrests take up the colors of the seats, while the masks of the ventilation vents are in the interior colors, black or polished aluminum look.
The whole field of color and inserts ("Colour & Trim") is structured in an innovative and youthful. For masks of ventilation vents is to provide a very wide range of colors. Series come in matte black (Attraction) or Gloss Black (Ambition). The unusual depth of vision that characterizes them is given by printed sheets covered with a transparent film of 3 mm. Depending on the tones of the tapestries, masks of ventilation vents are also available in gloss white, titanium gray, bright red, shiny and beige velvet. Even for the armrest, pockets for documents, the speaker grilles on the doors and rear compartment, and the "stern of the yacht" on the center console you can choose between different colors. Practical: the luggage compartment The luggage of the Audi A1 has walls flat and the crossbar of the loading is positioned very low. It has a total capacity of 270 liters and is very wide, because the dampers are mounted in the body in the external position. The base of the loading is very light and, in some areas, is made of natural fiber. Together with the backrest in the tilted position and the crosspiece of the loading is to form a continuous flat surface. Two pawls have the function of supporting the loading base when the rises. On the right wall is mounted a device for coupling multiple.
The operation of tilting the seat back is broken down quickly and conveniently, as the headrests can remain in place. The stowage volume in this way reaches the 920 liters, if the car is loaded up to the level of the roof. On request, Audi offers a luggage compartment package with practical storage compartments made under the load floor, a second latch multiple, a versatile cargo net, an outlet, a second port and an elastic strap for luggage. For winter sports enthusiasts can not miss a ski or snowboard bag. The quality of the boot is impeccable. The lock of the door is released electrically, even with the key to radio frequencies. The tailgate has a radius of very wide opening and locks perfectly in position. The lock cover, spring-loaded, protects from dirt: another typical detail that bears the signature Audi.
The infotainment systems
View of the young and urban target that targeted the Audi A1, multimedia and infotainment systems are comparable to those of class and with even some updated features. Their modular configuration, a typical solution of the Audi, offers the possibility of different combinations. The simplest variant is represented Chorus from the car as standard with a CD player compatible with MP3 formats and system volume control GALA speed-dependent. The chorus radio uses four speakers.
The next level is occupied Concert from the car, a brand new design. The heart of the system is constituted by a high-performance processor-based technology to double calculation unit. The control logic follows the principle derived from the Audi MMI superior. The display board with removable multi-colored diagonal of 6.5 "is included in delivery. The package is supplemented by a CD player, a slot for SD memory cards, an AUX IN jack and eight speakers. The Concert radio has a tuner run triple: the first tuner receives the radio program, the second searches in the background of other issuers and third queries the information service traffic.
Together with the Concert radio, Audi offers an optional package Connectivity, whose most interesting feature is the possibility of expansion of a radio navigation system. The hardware is already installed, and the customer can activate extended functionality at any time by giving specific authorization for the service. A SDHC card containing geographic data in the radio, so you need to integrate the functions of a browser. In addition to preparing for the navigation system, the Connectivity package also has a Bluetooth interface and music interface "Audi music interface" (AMI) for connecting a portable player without complications.
A high-end multimedia center: the MMI Navigation plus
The flagship of the range is the MMI Navigation plus, a high-end media center that represents the benchmark in the compact class. It consists of four main components: the main unit (Main Unit) with 60-gigabyte hard drive, the radio unit (Unit Radio), the MMI control terminal and the color monitor. The images, including the covers of audio tracks are displayed on a 6.5 ", are very sharp thanks to the high-resolution graphics screen and are depicted vividly and elegant. The navigation map with several models of cities and points of interest is shown in 3D. The MMI control unit is dominated by the joystick. It can be tilted in four directions, facilitating the selection of the various functions. To the sides and above the joystick houses the volume control, seven and eight softkeys hardkeys. They enable quick access to selections related to the vehicle, the sound quality, the car radio, the media, the menus, the phone, navigation and information system. The sound is emitted by eight speakers.
The MMI Navigation plus can store 20 gigabytes of music files. Includes two SDHC card slots and using a Bluetooth interface and the '"Audi music interface" (AMI) conveniently connects today's portable players. It comes with the DVD audio and video, and an intelligent voice control system can include twelve languages. The driver can then set the destination of the trip and the main functions of radio, multimedia and phone simply by using your voice. The display of the MMI Navigation plus is able to depict even Cyrillic, Japanese and Chinese. For the higher level of amenities is also provided for the integration of Google Earth maps and online services in the Audi, like the opportunities provided in the Audi A8.
For the MMI Navigation plus, the Concert radio, Audi of Serbia in a series of additional modules. They are an interface for standard Bluetooth phone and easily stream music and video, a CD changer for six CDs, and finally a radio tuner for reception of digital DAB, a transmission standard for the rapidly growing ability to integrate images and texts to radio signals. To make calls with comfort there is a predisposition for Bluetooth phones connected to the antenna of the car. The hi-fi enthusiasts can choose from two fine audio equipment: Audi Sound System 180-Watt 10-speaker, BOSE Surround Sound System or, where a 10-channel amplifier with 465 watts of power leads 14 speakers, subwoofer including. The BOSE Surround Sound System is able, through a special algorithm to issue the stereo signals into 5.1 surround mode. The digital amplifier picks up the acoustic noise using a special microphone and playback audio modulated accordingly. Moreover, the diffuse illumination of the subwoofer in the passenger creates a particularly striking.
To interconnect all these systems, starting from the car take the Audi Concert MOST bus loop with fiber optic cables. The MOST bus is particularly suited for the transfer of multimedia data and is used for the first time on a compact car. The configuration of the electronic system is very flexible and can expand to the rear with add-in even complex functions, or web browsing.
The engine
Gives the Audi A1 in four different engines. The two TFSI gasoline engines and two TDI cover a power range from 86 hp (63 kW) to 122 hp (90 kW). All engines utilize direct injection and turbocharging. This choice, combined with systems such as the Start & Stop and brake energy recovery, are the basis of high performance and low power consumption. Fuel consumption range from 3.8 to 5.3 liters per 100 km. Downsizing brought to perfection: the petrol engines The abbreviation TFSI indicates the combination of direct injection and turbocharging. This is a solution introduced for the first time by Audi five years ago. Combining the two technologies implies some important advantages. To the fuel directly injected is impressed an intense swirling motion which cools the walls of the combustion chamber. The cooling effect is important because it counteracts the occurrence of uncontrolled detonation, typical of turbocharged engines because of the high classical heat developed by the turbocharger. The coefficients of compression supported, that the motors Audi TFSI can thus be achieved, are constituted by a high efficiency of the engine.
The smaller of the two engines is the 1.2 TFSI. It delivers 86 hp (63 kW) and provides its maximum torque of 160 Nm at a speed between 1,500 and 3,500 rpm. The four-cylinder engine, paired to a manual five-speed gearbox, it accelerates the A1 from 0 to 100 in 11.7 seconds, allowing it to reach a top speed of 180 km / h. In the NEDC is satisfied with 5.1 liters of fuel per 100 kilometers, along which emits 11.8 kg of CO2. The newly developed four-cylinder 1.2-liter engine embodies an exemplary Audi's downsizing philosophy, the technical solution that prefers a turbo increase displacement. In fact, engine needs 1,197 cm3 and two valves per cylinder. During its design is aimed at easing a rational weights. The sealing rings of the pistons with elastic load reduced and compact bearings and connecting rod are low friction, while the oil pump operates as a function of the real need, thus absorbing less energy.
The base of the 1.2 TFSI in molten aluminum has its own cooling circuit separate from that of the head. After starting the water is circulated within the block. In this way the engine reaches quickly to temperature and thus shortens the phase during which the cold oil causes greater resistance to friction. The high-pressure injectors inject the fuel into the combustion chambers at a pressure that can even reach 150 bar. The boost pressure develops spontaneously through an electric actuator that actuates the waste-gate valve of the compressor turbo quickly and accurately, thereby helping to buffer the consumption of gasoline. The intercooler is positioned on the intake manifold in order to promote the reaction speed of the engine to the throttle control.
The 1.4 TFSI comes with 122 hp (90 kW). The maximum torque of 200 Nm is available constantly from 1,500 and up to 4,000 rpm. Therefore even the most powerful gasoline engine in the range A1 responds promptly in virtually all situations, even at low revs. The engine has a displacement of 1,390 cm3, four valves per cylinder, supercharged by a turbocharger is water cooled.
The 1.4 TFSI with S tronic seven-speed gearbox accelerates the A1 up to 100 km / h in 8.9 seconds and can reach a top speed of 203 km / h. With the six-speed manual transmission, which will be proposed at a later time, the step from 0 to 100 and the top speed remains unchanged. With the S tronic gearbox, the A1 only burns 5.2 liters of petrol per 100 kilometers with 0.1 liters more than the manual one. Emissions of carbon dioxide in the A1 1.4 TFSI S tronic amounted to 119 grams per kilometer (CO2 values of A1 1.4 TFSI with manual transmission is being measured).
Outstanding efficiency: TDI engines
The 1.6 TDI with 1,598 cm3 displacement is characterized by an internal friction minimized. This result stems from the use of a regulated oil pump, the piston rings, the lapping of the sliding rods of the cylinders, to the toothed belt, and finally to the piston pins of aluminum obtained by fusion. Their DLC coating is an advanced technology coming from engineering of racing engines. DLC stands for diamond-like carbon-carbon coating, indicating a fine and hard as a diamond. The piezo injectors of Common Rail are capable of portioning the injection into six phases differentiated for each operating cycle, to all advantage of the characteristics of combustion and the rate of harmful substances in exhaust gas. Even the smooth operation of the motor itself is affected positively. Inside the inlet manifold, a channel imparts tangential air inlet a rotary movement, while a spiral channel provides to improve the filling of the cylinder. A compressor with variable geometry turbine and an effective power input complete the architecture of the engine.
The Audi offers the 1.6 TDI in two versions. The most powerful, combined with five-speed manual transmission, delivers 105 hp (77 kW) and develops a maximum torque of 250 Nm between 1,500 and 2,500 rpm. With acceleration from 0 to 100 km / h in 10.5 seconds and a top speed of 190 km / h, the compact four-valve TDI showcases all its power, while the consumption of diesel fuel is limited, on average , to 3.9 liters per 100 km. The second version of the 1.6 TDI, which will be introduced later develops 90 hp (66 kW) and torque of 230 Nm between 1,500 and 2,500 rpm. In combination with the five-speed manual transmission accelerates from 0 to 100 in 11.5 seconds. The maximum speed reaches about 182 km / h, fuel consumption of 3.8 litres/100 km and CO2 emissions of 99 g / km (all figures are provisional).
All four engines of the A1 exploit a technology included in the Audi modular efficiency system, ie the recovery of energy that, thanks to an intelligent control of the alternator voltage, riassimila the energy generated during braking and deceleration. The recovered energy is temporarily stored in the battery, and fed into the on-board network in the next acceleration phase, thereby reducing the electrical capacity of the alternator and, consequently, the effort to drive by the motor. The Start & Stop, which is also another piece of the modular efficiency of Audi, is available as standard in all four engines. The system stops the motor vehicle is stationary and in neutral when the driver lifts his foot off the clutch pedal, and then restart it again so quiet, comfortable and fast the next time the clutch engages. The Start & Stop system, which can be switched off at will at any time, is fully operational even in the 1.4 TFSI with S tronic seven-speed gearbox.
A change in high-end: the S tronic seven-speed gearbox
The seven-speed S tronic combines the comfort of an automatic gearbox and the dynamism and efficiency of a manual transmission. It consists of two separate transmission units and two multi-plate clutches that manage groups of different gears. The large outer clutch transmits the torque by means of a solid shaft to the gear wheels of the group of odd gears (first, third, fifth and seventh). Around the shaft rotates a full hollow shaft connected to the second clutch, housed within the largest clutch. This second clutch, is smaller, is used instead of the drive sprockets of the group of gear ratios (second, fourth, sixth and reverse). The two partial units of the exchange are permanently active, but only one is integral with the motor. When, for example, the driver accelerates in third, in the second gear is already pre-engaged to the fourth. The inclusion of the new relationship takes place through the transfer of power from one clutch to another. The gear change takes only a few hundredths of a second, almost without noticeable interruption in tractive force; changes are so dynamic, soft and comfortable to be almost imperceptible to the driver. The footprint of the S tronic seven-speed, with its 37 cm m in length, is extremely small, and weighs just 70 kg is very low for a change so complex. The two clutches operate dry without a dedicated oil supply system, a fact which contributes to further increase the already high degree of efficiency of the gearbox. The oil is not necessary for the actuation of the change. The supply pump, electric type, operates according to the actual requirements. The seven-speed transmission are kept short in favor of a sportier driving, except the last, long, allowing you to travel at low speeds and save fuel. To operate the S tronic seven-speed, the driver can operate a lever of change, or use the paddles on the steering wheel (optional), as in a sports car. Also available are two fully automatic modes. In D mode the system of managing change causes the engine speed as possible at low revs to save fuel in the S mode the pace is more sporty and high engine speeds. A support system during cue that facilitates hill start is standard, for the A1 with manual transmission, however, can be ordered on request.
The chassis
The Audi A1 is the front-drive sporty car in the premium compact class. It is agile and maneuverable in the city, stable and accurate on the open road and comfortable on the highway. This enormous versatility is due in large part, to the elaborate chassis with a favorable distribution of loads. The distribution of axle loads is one of the things that Audi's engineers have given great importance in the design phase. The front overhang of 808 mm is remarkably short. Depending on the engine, only 61% or 63% of the weight of the car rests on the front axle. In this report contribute numerous technical details among which also the position of the battery, which in most of the engines is housed under the boot. With a base weight of just 1,040 kg, the A1 is the lightest car in the premium compact class. The suspensions of the front wheels exploit a classic McPherson combined with lower transversal arms of triangular shape and movement geometry optimized. The subframe is manufactured in high-strength steel. Interconnected to the rear arm shock is physically separated from the spring. The support bearings were overhauled in order to optimize the whole mechanism in terms of driving comfort and dynamism. The A1 has unusually wide carriageways of 1477 mm and 1471 mm at the front to the rear.
Accurate and efficient power steering
The A1 is equipped with a hydraulic power steering rack in which the oil is put into circulation by an electric motor. It follows un'incrementata effectiveness of operation compared to a conventional hydraulic closely. As the speed the motor rotates more slowly reducing the effect of support for the steering, while with steering angles of great magnitude the oil flow increases. The steering response is precise and sensitive control of the steering wheel absolutely immediate. A short transmission ratio of 14,8:1 makes the steering very direct. Thanks to the lateral movement of the front wheels turning circle does not exceed 10.6 meters, a factor which gives an extraordinary agility to vettura.La Audi has all the components dall'autotelaio calibrated with the aim to achieve balanced performance with a sporty emphasis. For example, the bearings of the front transverse arms are very stiff in order to ensure a high lateral grip, while the rear bearings have a reaction to the load more gradual in order to improve comfort. On all four wheels are mounted telescopic shock absorbers with gas additional elastic elements in polyurethane. Stiffer sport suspension is standard on the Ambition line construction, or are available as an option in the line Attraction. Alternatively, you can also opt for the chassis sport S line from quattro GmbH.
Dynamism and Safety: ESP with electronic locking latch
All engines in the Audi A1 have a new technology: the electronic stabilization program ESP with electronic locking latch. It, like a mechanical locking differential, has led to a further increase in the dynamism of a car which is already very agile. As soon as the control unit detects an excessive lightening of the load on the wheel inside of the curve, it has a slight targeted intervention on the brake. This intervention consists of a delicate support of the seals on the disk with minimal pressure. The action is smooth and continuous. It takes place even before the wheel loses traction with the road more, a situation that would ultimately result in an absorption significantly more energy to the braking intervention. The slight braking impulse transfers torque not exploited by the other wheel in a wheel taken outside of the curve, that can be used for the benefit of added traction. At the same time, the imbalance of the tensile forces generates a certain pair of yaw, which corrects slightly the trajectory of the car originally set by the driver towards the inside curve. The result convinces in every respect: in extreme situations the road behavior of A1 remains significantly longer than the effect of neutral and understeer that occurs in accelerating curve is nearly neutralized. The electronic stabilization program ESP can thus be mobilized at a later time and in a less invasive, admitted that there is a need. The conduct of travel becomes even more precise, more responsive, more stable and neutral, objective safety and subjective confidence in the car increases even more.
Sports: the wheels and brake system
ESP A1 controls the wheel brakes powerful and generously sized. The ventilated front discs have a diameter version of 256 mm on the 1.2 TFSI and 1.6 TDI 90 hp (66 kW) and 288 mm on cars with more powerful engines. On the rear wheels of all the versions of the car are mounted solid discs of 230 mm in diameter and floating-caliper of aluminum. In case of emergency braking, the brake lights start flashing to indicate the situation of danger to other road users. A stationary vehicle begin to flash your hazard lights of emergency. The line construction Attraction offers 15 "wheels of steel or, on request, in aluminum. The version of Access is geared to maximum use of aerodynamics and tires mounted so the size 185/60 for their reduced rolling resistance. The most powerful use versions instead tires in size 205/55. On the Ambition line construction are available 16 "wheels of light alloy in two different designs, types of tires 215/45. Are also available on request type runflat tires and rims 16 "with design alternatives.
Also like the optional Audi also provides elegant wheels 17 and 18 "forged aluminum, polished on request to partially or with colored decorative elements, and with wide sport tires from size 215/40. Quattro GmbH offers in combination with the S line sports chassis 18 "wheels and wide tires in size 225/35. The range is completed by winter rims 15 and 16 ". The A1 comes standard with a tire repair kit for the Mobility Tire System placed under the base of the trunk. Optional features also include a system for monitoring tire pressure.
The equipment
The Audi A1 is available in two equipment lines: Attraction has a strong personality and a rich equipment, the Ambition is sporty and dynamic. In both lines can be combined with the Media Style Package, which includes interesting elements in the field of infotainment and interior design. Some elements, such as the navigation package, can be purchased later, an offer that keeps the A1 young and attractive over the years. The package interior lights in LED technology, integrated in the package or ordered separately, gives a striking light effect the cockpit. Attraction is the version included items such as very fine chorus radio, central locking with radio remote control, electrically adjustable outside mirrors, power windows and height-adjustable driver's seat. To ensure the safety of those on board then there are, as standard, two front airbags, side airbags for the pelvis and thorax and head airbags. The program also limiters belts, integral head restraint system Audi and brackets for mounting Isofix child seats in the rear. A request can also order a device for deactivating the front passenger airbag. line construction Ambition is recognizable at first glance thanks to the presence of wheels 16 "alloy wheels, and fog lights and exhaust polished. The sports seats have facilitated the function "easy entry" and a lumbar support. Also the front passenger seat can be adjusted in height. The gear lever knob, steering wheel and handbrake lever are leather, and plastic moldings and access some areas of the interior are in aluminum look. The driver information system with trip computer and integrated efficiency program, is standard on the Ambition line.
The package consists of an interface Bluetooth Connectivity, of '"Audi music interface" (AMI), the voice control system and preparing for the navigation system. At a step higher you place the package Navigation package with integrated connectivity and function navigation. Regardless of the package there is a wide range of modules for infotainment. The offer starts from the car Concert and ends with the MMI Navigation plus high-performance system with BOSE Surround Sound. For the audience of the A1, Audi has developed a new solution, with trendy colors and materials geared to a young and urban lifestyle. Optionally, some components such as seat covers, housings of the vents, the surfaces of the door inserts are illuminated in attractive colors.
Luxury superior
Many extras of the Audi A1 come directly from the upper class. For the exterior are, among others, the xenon plus headlights with daytime running lights and rear lights incorporating LED technology. Audi has also devoted much attention to the issue of lighting and visibility. The high beam assist device for recognizing other vehicles and lowers the lights themselves. The light and rain sensor, available as an option, when enabled individually on the low beam and enters the windshield wiper. The glass roof makes the interior bright and airy. The key to comfort, a further innovation in the compact class can safely remain in his pocket: the lock of the A1 is released when the driver pulls the door handle, and the engine starts up when you press the button start / stop.
As an option, Audi offers an antitheft system with alarm, heated and folding door mirrors, a speed control system, a ski bag, a compartment in front center armrest, storage package with a package and then boot a system using parking on two levels.

In the competition kit legends interior, which will be available only at a later time, given the special decorative covers for air vents, interior door handles, center console and the rear view mirror. The Plus version provides a coating for leather steering wheel, gear lever and handbrake.
Young and urban: the target of A1
The Audi A1 is directed by an audience that can be divided into three groups united by similar desires when it comes to cars: cutting-edge technology and customization possibilities. The first group consists of people aged between 25 and 29 years, predominantly male and the beginning of their work. They are young, athletic and mostly single. So far they have often driven used cars and now wish to buy their first new car. Another group consists of women aged 30 to 40 years success-oriented. They are educated, living alone or with their partner and are interested in fashion, culture and design. The third group is represented by families who already own one or two cars. Here, the A1 will be used by parents or their young children.
Produce a host of modern robot by orange elegant movements she performs in a complex dance. But the equipment was still at work, you're just exercising. They're just trying out the latest moves of their programming. When the choreography is perfect to tailor "the dress sheet" to more than 500 examples of the new Audi A1 a day. Peter Vloeberghs, Director of the new A1 car body construction department, was captivated by the new assistants: "They emit only a faint hum, almost a melody accompanied by slight whistling. No comparison with the whistle blows and the old noisy robot. These are also faster and consume less. "
Audi has invested 300 million euros in the development of the plant for the new A1 located in Forest, a suburb southwest of Brussels and detected by Volkswagen in 2007. Much of the money has gone into construction in the area of the body. The Audi's compact premium offer in Belgium a guarantee of a job long term. With training and further targeted Audi has prepared intensively from the beginning the technical team in Brussels the new Audi Production System APS. Strict quality control and a continuous program optimization of products and processes in the center of competence, control and analysis APAZ, which cost ten million Euros, are the guarantee of excellent quality. Hundreds of robots: the body construction In the construction of the body, most of the work is done by 368 new robots equipped with the latest technology, in service in welding sheet metal. The quality of the welding points is controlled with ultrasound in three stations, especially in areas which are mounted a steel of higher strength hot-molded. In addition to a total of 200 units robot geometric and handling robot 71 are used for measurement. Through their detection instruments measure three-dimensional, directly into the production flow, the accuracy of 370 points of the body and an additional 75 of the applied parts. Audi is very strict in terms of quality and precision, does not tolerate inaccuracies of any kind, nor the order of tenths of a millimeter. Obviously, then, also presents A1 junctions, high precision, and the pattern perfectly parallel thin areas of union between fenders, doors and sides.
"To produce quality, the environment must also be oriented in every respect to quality" , indicating the umbilical Vloeberghs stresses produced by ionization on the drain opening of the boot. For stability and superior aesthetics, the channels of the roof and tailgate are welded with laser techniques.
140 lines: mount
The mount has undergone substantial revision. "The assembly line for the A1 was reduced from 240 to 140 steps of work," says Jan Maris, director of the assembly. The pace of the production line, used previously for the Audi A3 Sportback has been speeded up to A1, consistent with the principle of Audi production oriented to the future that provides logical control simpler and shorter routes. A wooden floor and lots of non-slip ergonomic devices are intelligent witnesses of the new way of thinking about production. The bodies run through the assembly line at a height optimal for the physical demands of the mechanics. Tombstones Special electrically adjustable allowing the cockpit to steer well placed for processing. For easy mounting to a vehicle, Audi has developed a special ergonomic seat that the mechanic uses to make the screw connections on the motor side.
The various pieces are stored in so-called "supermarket" and come to the mechanic through a clearing house for the shortest way, sorted according to the real business needs in special cages. In Brussels, for supplying forklift trucks are no longer in use, because the transport operations are expedited in a safe and flexible by a train. Upstream of the production is the modern center of competence, control and analysis APAZ. The main task of the specialists of the Centre is the quality control, an activity in which you seek even the smallest irregularities, starting from the prototypes. These specialists are at the forefront since the birth of the first pre-series models. They are organized in teams of mixed competence, composed of Germans and Belgians.
"There is quality when the customer returns, and not the product" , this is the word that heads a panel dell'Audi ATC Training Center and is also the motto of the whole factory. Alfons Dintner, Chief Director of the Technology Department and logistics, said: "With the production of A1 we give the Brussels plant can build a future for himself."
And, in parallel, the possibility of transferring to the compact class car all the quality of the premium Audi, thanks to an extremely precise manufacturing.
Among the many activities of the factory in Brussels aimed at protecting the environment should be mentioned a tub of rainwater retention, efforts to optimize the energy requirements for the assembly of the bodywork, the extensive work of cleaning the land and the creation of a sewer system modernized. In the frame of the founding ceremony, Audi has also planted 100,000 new trees on the outskirts of the city. Prices The price list is included among the 17,150 euros for version 1.2 TFSI Attraction 86 hp to 26,700 euros of the 1.4 TFSI S Tronic 185 bhp.
