Is the Audi e-tron powerful enough for highway driving?

The RS e-tron GT can sprint from 0 to 100 km/h in a blistering 2.5 to 3.3 seconds (depending on boost). For buyers considering the Audi e-tron, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
