The V6 HDi DPFS (particulate filter) diesel engine is mated to a 6-speed automatic gearbox developing 150 kW (208 bhp) that drives the front wheels with each rear wheel electric motors developing 400 Nm torque and 15 kW (20 bhp).
In the city, the C-Métisse can operate in ZEV (Zero Emission Vehicle) mode – an "extended'", completely silent all-electric mode with a range of around 3 km at 30 kph – as well as on roads demanding successive acceleration and deceleration. In this second case, the hybrid architecture makes it possible to limit consumption by using the two forms of energy together.
On motorways, the V6 HDi diesel combustion engine with a DPFS sets high standards of efficiency, based on its intrinsic qualities.
By controlling fuel consumption and thus pollutant emissions, C- Métisse boasts combined cycle consumption levels of 6.5 l/100 km for CO_ emissions of 174 g/km.
No sacrifices have been made in terms of driving pleasure, which remains a key priority for motorists. If the driver makes prolonged use of the accelerator pedal, the electric boost function kicks in to provide the torque required. This function combines the torque of the combustion engine with that of the electric motors to endow C-Métisse with a level of performance worthy of a high-spec sports vehicle, without pushing up fuel consumption. C-Métisse accelerates from 0 to 100 kph in 6.2 seconds and takes 25.4 seconds to cover 1,000 m from a standing start.
Rather than pursuing the quest for ever higher speeds that are not practicable in normal traffic conditions, the emphasis has been placed on driving pleasure with clean, fast acceleration. For example, C-Métisse accelerates from 80 to 120 kph in 4.2 seconds. The vehicle remains in 4-wheel drive mode while the boost function is active, since the electric motors drive the rear wheels while the combustion engine drives the front wheels. Thus ensuring impeccable traction.
Also, when the ESP sensors report low grip conditions, C-Métisse can activate its electric motors and thus adopt a 4-wheel drive configuration. The electric motors deliver improved traction and ensure full use of the potential of C-Métisse in all conditions and in complete safety.
