2007 Audi RS 4 Quattro - Road Test - Car and Driver (blog)
At 150 mph down the long straight at our high-desert testing ground, the '07 Audi RS 4 performs the same gentle rear-end boogie I remember from an autobahn experience with it in Germany. That particular dance partner was a German model we were testing alongside a BMW and Mercedes-Benz, and all three drivers that day remarked on the peculiar rear-end gyration. At the big track at Willow Springs International Motorsports Park in Southern California where Audi staged its stateside introduction, the RS 4 would reach maybe 130 mph down the pit straight. Perhaps it has something to do with the Quattro all-wheel drive, or the car's 58. 3/41. 7-percent front-to-rear weight distribution. Not many owners will ever see speeds that high. Most racetracks don't have straights long enough to allow this kind of speed. Still, you don't need huge top speed to enjoy the RS 4's 420-hp direct-injection V-8. Just about anywhere will do. The engine pulls smoothly from idle, with abundant thrust available from 2300 rpm. In fact, 90 percent of the car's peak torque is available between 2250 and 7600 rpm. With its 420-hp peak in full bloom at 7800 rpm, the RS 4 is blessed with an engine that is flexible and rev happy. Source: www.caranddriver.com
