The Audi A6 e-tron is a concept for now, but Audi says it's super close to what the production car will look like. It's based on the scalable Premium Platform Electric (PPE) architecture that can be lengthened, lifted, and widened for a variety of different EV models. It will be sold alongside the gas-powered A6—and it's likely the first EV we'll see on the PPE platform that underpins future electric Audis. The A6 e-tron concept uses two electric motors with a combined output of 469 horsepower. All PPE vehicles have 800-volt charging capability, and this big sedan could have as much as 400 miles of range on a single charge. —Austin Irwin
