The redesigned 2019 A8 is one of the most impressive cars we’ve tested. This ultra-luxury sedan is immensely satisfying to drive, thanks to its smooth and responsive powertrain, an almost magic carpet ride, and elegant interior.
We were impressed by the 335-hp, turbocharged V6 engine, which delivers the acceleration and performance of a bigger V8 engine. It is paired with a smooth eight-speed automatic transmission that shifts quickly and imperceptibly. This powertrain doesn't suffer from any of the delays associated with turbo engines. The A8 has a 48-volt mild-hybrid setup, which uses a large battery to reduce the power demands on the engine. All of this combines to give the A8 fuel economy of 21 mpg overall, which is commendable for such a large and quick all-wheel-drive car.
