Metropolis features a plug-in hybrid drivetrain that changes the operating mode to suit the situation. Full-electric mode is used on start-up, in the city, at low speeds and during deceleration. It relies on an electric motor that ran raise its output from 55 bhp (40 kW) in continuous operation to a peak of 95 bhp (70 kW).
Combustion mode is used at cruise speed on the road or motorway when the V6 2.0l (272 bhp) petrol engine is operating at maximum efficiency.
The two forms of operation can also be combined during acceleration to provide extra power (Overboost function), delivering up to 460 bhp in four-wheel drive mode when more grip is required.
To take full advantage of its dynamic capabilities, Metropolis is fitted with Hydractive suspension. This feature delivers excellent driving comfort while keeping the vehicle at a constant height for improved aerodynamics and thus lower CO2 emissions.
