Audi S7

When it comes to performance on the Audi S7, it's easy to get caught up in the prodigious power and breathtaking speed. Yet even with 420 twin-turbocharged horsepower and 406 pounds-feet of torque on tap, the engineering greatness extends far beyond the engine. The S7 rides on a sport-tuned Audi adaptive air suspension that's fittingly firm, yet exhibits the natural resilience inherent to air springs, along with the smarts to automatically lower itself for better high-speed stability. The Audi quattro all-wheel drive system features a rear power bias for a purer driving feel, plus a torque-vectoring rear sport differential to enhance precision in cornering. Quick, vivid steering helps infuse every turn with excitement, and with its dual-clutch S tronic transmission, the S7 makes rapid-fire shifts through its seven speeds — a key reason its performance seems to surpass expectations.

In the S7, performance and safety go hand in hand. Its four passengers receive protection from eight standard airbags, including driver and front passenger dual-stage airbags, thorax side airbags, knee-level airbags, and Sideguard head curtain airbags (plus available rear thorax side airbags). Electronic Stability Control helps secure the car's intended path at all times, and in the event of a collision, intelligent sensors automatically unlock the doors, switch on interior and hazard lights, and cut off fuel flow to the engine.
