Four modes to suit your moods. The standard COMFORT mode offers a balance between sporty performance and fuel efficiency. SPORT mode engages the power of the combustion engine, with extra boost provided by the electric motor. ECO PRO mode supports a more efficient, optimized driving style that can be used in both all-electric mode and blend mode. Finally, eDRIVE mode is purely electric, offering a max speed of 75 mph for a totally tailpipe emission-free ride.
