Road & Track takes the Mighty Audi RS 4 and the Carrera C4S to the new Miller Motor Sports complex in Utah. R & T's conclusion: The Porsche is a true sports car, while the Audi is an awesome sports sedan that costs less than the Porsche! Okay, so we probably could have figured that out without Road & Track's help, nevertheless;

The Audi RS 4 and Porsche Carrera 4S are about as different as two cars can be. One’s a sedan, the other, a coupe. A V-8 resides up front in the Audi vs. a flat-6 at the rear for the Porsche. And the sedan carries about 60 percent of its weight atop its front wheels while the coupe has a similar amount resting over the rear axle. But what they do have in common, beside their German origins, is all-wheel drive, a similar power-to-weight ratio and, most important, a thrilling ride on either road or track. </td>
