For more than a decade, the editors of the weekly automotive-enthusiast magazine have scoured show floors in Detroit, Geneva, Paris, Frankfurt and Tokyo, selecting winners in four categories: Best in Show, Best Concept, Most Significant and Most Fun.

The 2008 AutoWeek Editors' Choice Award winners for the Best of Detroit are:

BEST IN SHOW: Chevrolet Corvette ZR1 -- "We award Best in Show to the vehicle that we feel will be best remembered five years down the road. Simply put, the Corvette ZR1 is the baddest of the bad. The 620-horsepower machine with carbon-fiber body rightfully takes its place as Best in Show," said AutoWeek Editor and Associate Publisher Dutch Mandel.

BEST CONCEPT: Cadillac CTS Coupe -- "The vehicle named Best Concept is one we're most hopeful to see built. Almost unanimously, the AutoWeek editorial staff selected the CTS Coupe as most deserving of the award. It is the next iteration of the dramatic styling Cadillac has brought to the marketplace."

MOST SIGNIFICANT: Ford F-150 -- "Because Ford brought so many significant vehicles to this year's show, the decision of what vehicle to award Most Significant was a tough one. From the Explorer America, a unibody-constructed, friendlier sport/utility vehicle, to the Verve, the best-looking small car Ford has built for America in generations, the F-150 is Most Significant for what it means not only to the company but to the American ethic. The F-150 is Ford tough-and so was this decision among quite an impressive lineup of products Ford has on display."

MOST FUN: Audi R8 TDI Concept -- "Who couldn't see themselves with a 6.0-liter V12-powered sex-mobile like this R8 supercar? With turbodiesel power and torque that could move not only houses but emotions, it's AutoWeek's choice as Most Fun."
