Tesla P90D vs APR Audi RS7 - AWD 4 Door Battle

In possibly the strangest of comparison tests, Auto Express pits an electric luxury sedan up against a twin-turbocharged V8 luxury hatchback up against a high-performance diesel SUV. The only two things each of these three cars have in common is the fact that they’re all-wheel drive and ludicrously fast. The Tesla Model S P85D vs the Audi RS7 vs the Alpina XD3. What a test. Steve Sutcliffe of Auto Express, a man not unfamiliar with extremely fast cars, takes each of these three ridiculously fast machines on the track to see how fast they all are.
