After its introduction last year, Audi brings back its mid-size luxury coupe for 2009 with no major changes. The S5 will be powered by a 4.2L V8 engine paired with a six-speed manual or automatic transmission, boasting a projected horsepower rating of 354 and a 0-60 time of about 6 seconds. Other features will include a 2+2 seat configuration, a high-end leather interior trim, 18-inch alloy wheels, exclusive exterior paint, sport suspension, three-zone climate control, and a sound system with CD player. Innovative features include an electromechanical handbrake, an all-plastic key, and Audi's MMI technology. Options include keyless engine start, a rear parking assist system, bi-xenon headlights, and a premium sound system.
