Driving experience

Audi Q6 e-tron

As a model line, the Q6 e-tron accelerates strongly and silently on its electric motors, and the ride filters out poor surfaces. It feels planted and secure rather than sporty. Regeneration is adjustable for one-pedal driving in town. The quattro has 388 hp, and the 800-volt system charges at up to 270 kW DC, so long trips need short stops.
