A two-door Cabriolet version joins the Sedan, with a limited run of just 300 cars. SIRIUS satellite radio is made standard and two new packages are offered on the Sedan: the Titanium Package adds titanium-colored 19-inch wheels, black grille and trim, black headliner and Piano Black inlays, and the Exclusive Package adds red leather seat centers, contrasting red piping and red stitching on the shift boot, hand brake and steering wheel.
While the 340-horsepower S4 continues to be the performance king of the regular production series A4 lineup, the limited-production RS4 significantly ups the ante (and the price) with exclusive upgrades to the engine, brakes and suspension, along with unique bodywork draped over a wider front and rear track. As for its primary competition, the RS4 bests the current six-cylinder BMW M3 by offering two more doors, four-wheel as opposed to two-wheel drive and two more cylinders in an engine that puts out 87 more horsepower.
The 2008 Audi RS 4 is the German automaker's latest effort, especially in the U.S. market, to establish itself as a brand known for performance and exclusivity. The limited-production, high-tech RS 4, with its four-door sports-car attitude, fits perfectly with Audi's marketing philosophy that a commitment to racing and high performance will impress and attract more buyers to the regular production series of A4 models.
