2007 Audi RS 4

The Audi RS4 is the German automaker’s latest and most dramatic effort, especially in the U.S. market, to establish vehicles designed and built by its quattro GmbH tuning subsidiary as the pinnacle of Audi performance and exclusivity. The goal is to have the RS logo worn by quattro machines inspire the same soul-stirring and heart-pumping reaction that an AMG or M Series badge does on respective Mercedes or BMW vehicles. The limited-production, high-tech RS4 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.

The RS4 is definitely for the hardcore driving enthusiast willing to put up with a stiffer ride, snug fitting sports seats and an engine that can, when provoked, sing louder than the stereo. Those who prefer looking sporty while riding pretty will be better served by the S4 or an A4 with S trim package.

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.

Driving Impressions The RS4 is one of the best handling cars#151;with either two or four doors#151;we have driven recently. The DRC suspension, which controls pitch and roll via fluid transfer between diagonally.

connected dampers that share a central reservoir, makes the RS4 feel incredibly balanced no matter the speed or road conditions. At the same time, the ride, though firm, remains comfortable enough to not rattle your teeth.

The combination of DRC and a sport-tuned all-wheel-drive system produces an incredible level of cornering grip that, in concert with the responsive and communicative steering, allows the driver to place the RS4 exactly where desired, and the big disc brakes provide confident and impressive stopping power. The growl and responsiveness of the V8, however, is more like an American muscle car.

Pushing the dash-mounted S button invokes the Sport Mode for an even louder exhaust note and an even more responsive throttle response#151;the latter best suited for the track. Audi claims acceleration for zero to 60 miles per hour of 4.8 seconds, but that seems conservative.

Under the Hood

The RS4 is powered by a high-performance, normally-aspirated version of the 4.2-liter V8 used in the A6, A8, and Q7. The four-valve, all-aluminum engine features FSI direct gasoline injection and a compression ratio of 12.5 to 1. It delivers a maximum of 317 pound-feet of torque at 5,500 rpm, with 90 percent of this torque available between 2,250 and 7,600 rpm, and makes 420 horsepower at 7,800 rpm. It thus achieves the traditional high performance target of 100 horsepower per liter, and gives the RS4 a weight-to-power ratio of just 10.6 pounds per horsepower.
