The Audi S5 was launched at the 2007 Geneva auto show in Switzerland along with the Audi A5. The all-new 2008 Audi S5 is a two-door, four-passenger coupe with solid balance and grip. Its sporty moves and sleek looks make it the ideal machine for the generation next. For 2008, the S5 is fitted with a powerful V-8 engine, sport tuned suspension, upgraded brakes, and luxurious interiors.

The 2008 Audi S5 is the performance-oriented version of the A5. The 4.2-liter direct-injection V-8 generates 354 horsepower and 325 pound-feet of torque. The engine is paired to either a six-speed manual or a six-speed automatic transmission. The standard Quattro all-wheel-drive gives 0-62 mph in 5.1 seconds.

The distinguishing features of the 2008 Audi S5 from the A5 are vertical chrome inlays in the grille, quad tailpipes, and aluminum mirror housings. The single-frame grille is finely customized to the S5. It is equipped with 19-inch wheels and comes with an overall length of 182 inches (53.9 inches tall and 73 inches wide). The projector-beam headlamps are framed below with LEDs. The car's outside beauty flows inside. The materials are luxurious and high-tech. Satin-finished accents and leather seats contribute to cozy comfort in the coupe's roomy interior. The driver has the option of quickly and effortlessly controlling various functions either through a switch or Audi's Multi-Media Interface (MMI).

Six airbags (front, side-impact, and side curtain), high performance brakes, an electronic stability system, four-wheel disc anti-lock brakes, and traction control are some of the standard safety features of Audi S5.
