Here’s a gallery of the A5 e-tron quattro in cold weather testing and the unique instrument gauges of their EV. The e-tron is Audi’s name for their electric drive vehicle model range. If you notice the picture showing the drive components, unlike earlier etron models, there is a gasoline engine on this prototype but it doesn’t drive the car at all. In this prototype, the gas engine is there only to power the battery – the car is still moved by the electric motors only. Previous etron models had no combustion engine at all.
