About two years after the presentation at the Los Angeles Motor Show, Honda CR-V Hybrid arrives in Europe (production will start in October while deliveries will take place in early 2019): this is how the i-MMD hybrid system works (Intelligent Multi-Mode Drive) , for the first time available on a Honda SUV in Europe.
Honda's hybrid system consists of two electric motors (powered by a lithium-ion battery) and a 2-liter Atkinson i-VTEC petrol engine , optimized to be as efficient as possible. First of all, the fact that this powertrain eliminates the need for a mechanical transmission: in its place there is a direct transmission , equipped with a single fixed ratio, which guarantees a transfer of the most fluid torque . Absent therefore the traditional (and often criticized) e-CVT gearbox present on the classic hybrids in use on the other hybrid vehicles on the market.
The continuous transmission allows you to travel according to three driving modes . For all, direct transmission is able to scale automatically without torque interruptions :
EV Drive : the petrol engine is off and the car travels in 100% electric mode (autonomy is not specified)
Hybrid Drive : the excess energy generated by the petrol engine feeds the second motor / generator that integrates the electricity supplied by the battery system. This is the most efficient mode at medium-low speeds, where the electric motor intervenes for about 50% of the time (one third of the time, however, at higher speeds).
Engine Drive : the wheel traction (which, we remember, is both front and full ) is provided only by the petrol engine (the electric only intervenes in the event of abrupt shooting). This will be the most efficient mode at high speeds, for example on the motorway.
Among the peculiarities of the i-MMD system there is an "imperceptible" passage between the different power sources . All information related to the hybrid system (energy flows, driving mode) will be displayed on the central display with DII (Driver Information Interface) .
At the launch, Honda also confirms the fuel consumption and CO2 emissions figures of the new CR-V Hybrid. Based on NEDC tests, the front-wheel drive model records CO2 emissions of 120 g / km , with consumption in the combined cycle of 5.3 l / 100 km . The four-wheel drive version instead emits 126 g / km , with an average fuel consumption (in the combined) of 5.5 l / 100 km .
