2008 Audi R8

The Porsche 911 (*est. $73,500 to $191,700) has been the standard-bearer for decades – until now, auto writers say. The new Audi R8, a direct competitor to the 911, is raising the bar. With a base price of $109,000, the R8 is not "affordable" but is well worth the price, especially when compared with other expensive sports cars, according to some reviewers. Not only can the Audi R8 keep up or beat its rivals around the racetrack, it's also more comfortable than many others on the road, delighting critics with its easy-to-drive manner.

But it can't beat all its competitors in sheer acceleration, reviewers are quick to point out. The Porsche 911 Turbo coupe or GT3 (*est. $107,500 to $126,200) and Corvette Z06 (*est. $71,275) are more powerful and faster, but it's the R8's refinement and overall performance that makes many critics still choose the Audi. While most reviewers love the unusual and aggressive styling, a few say that the proportions are awkward, or they dislike the "sideblades" adorning its flanks. Other points of criticism include rear visibility and a miniscule 3.5-cubic-foot trunk, although there is additional storage space behind the rear seats.

The Audi R8 has garnered the most accolades of any sports car researched this year, and there are dozens of articles about it. Some of the best comparison tests are conducted by Edmunds.com, as well as by Popular Mechanics, Car and Driver and Motor Trend magazines. Edmunds.com also has a good general review. Automobile and Robb Report magazines each select the R8 as their car of the year. Cars.com and WindingRoad.com provide detailed driving impressions in inclement weather.
