Speedy, sporty, streamlined, solid, and sophisticated. These are the five Ss in the 2008 Audi S5, a new sports coupe being introduced with the new A5 sedan. Based on a new platform and a new design by Walter de Silva that incorporates a trapezoidal front grille, frameless windows, and angular headlamps, the 2008 S5 will distinguish itself from its sedan counterpart with a different engine, different exterior styling, and beefed up performance parts.

The 4.2-liter direct injection FSI comes from the R8 and delivers 354 hp and 325 ft-lbs of torque with a 6-speed manual. A DSG automatic gearbox should arrive later. Audi clocks its 0-60 time at 5.1 seconds. On the outside, four exhaust pipes, aluminum side mirrors, a chrome grille, body-colored moldings and side skirts, a larger air intake, and bolder bumpers identify the S5's racing pretensions over the A5. It also boasts a sports suspension, interior Recaro sport seats, larger brakes, performance tires for the 18-inch wheels, and carbon fiber accents in the cabin.

A unique trans-axle design that places the V8 engine behind the front wheels allows for lower overhangs and a wider wheelbase, which improves overall handling, balance, and driving response. Combined with the quattro all-wheel drive, the 2008 S5 hugs the road in various driving situations. Though the quattro affects initial acceleration speed and takes away some of the rear-wheel drive performance found in other sports coupes, the superior system does default to a 40/60 front/rear torque split.

The four-seater sports coupe will be customizable, but starts with a CD player, tri-zone climate control, an electric parking brake, push-button ignition, a navigation system, tilt sunroof, and a Smart Key, which records fault codes that then can be read by your mechanic. While that may sound like too much practicality for what Audi hopes will prove to be a fun ride, early reviewers have been impressed with the combination of highway speed and handling with overall safety and driver comfort.
