The electrical system in the e-tron GT concept car runs at 800 volts, whereas most modern EVs currently operate at a capacity of 400 volts or less. The body and roof of the e-tron GT are made of carbon fiber-reinforced polymer (CFRP), and the car uses the same multi-material construction philosophy as other Audi vehicles like the A8.
