Our hybrids can be driven purely electrically in EV for short distances. This makes for reduced emissions and almost silent driving. D mode is set up for optimised fuel consumption and main drive power comes from the 2.0 TFSI engine. The program maintains an efficient balance between fuel consumption and performance. Features of this mode include electric drive, gliding, start-stop, boosting and recuperation. The boosting feature enables the electric motor to boost the combustion engine, briefly generating additional output and torque for the hybrid system. The S mode features sporty engine and transmission settings and performance can be boosted by the electric motor.
