Major changes included:
In 2013, Audi released the first-generation S7, which was a high-performance variant of its A7 sedan. The S7 was nearly identical to the A7, with the exception of its badging and the S7's quad-exit exhaust system. Under its hood, the S7 set itself apart from the A7, thanks to a 4-liter twin-turbo V8 that produced 420 horsepower and 406 pound-feet of torque. The power headed through a dual-clutch, seven-speed auto transmission on its way to all four wheels.
