The high-performance luxury sedan isn't exactly a new concept. Models such as the BMW M5 and AMG versions of the Mercedes E-Class have been around for decades. And yet we have to give credit to Audi for putting its own distinctive spin on this class with the new 2021 RS 7. It all starts as an A7, which is Audi's fastback version of the midsize A6 sedan. From there Audi gives it the full RS treatment, including a muscular turbocharged V8 good for 591 horsepower, a specially tuned air suspension, optional carbon-ceramic brakes, and flared fenders covering 21-inch wheels with summer tires.
