Driving experience

Audi e-tron

As a model line, the e-tron accelerates strongly and silently on dual electric motors, and the air suspension soaks up poor surfaces. It feels heavy and planted rather than agile, and it is happiest cruising. Regeneration is adjustable for one-pedal driving in town. The 55 quattro has 408 hp and a 95 kWh battery, but real-world range is well below its WLTP figure.
