Corvette Racing's Small-Block V-8 Wins Global Race Engine of the Year Award
Panel of Experts Selects Le Mans-Winning LS7.R as Global Motorsport Engine of the Year
COLOGNE, Germany - GM's small-block V-8 added another accolade to a long list of honors when Corvette Racing's LS7.R was named the Global Motorsport Engine of the Year at the inaugural Professional Motorsport World Expo in Cologne, Germany, on November 9. The race-prepared LS7.R engine, which shares its architecture with the production LS7 small-block V-8, propelled Corvette Racing to its fifth GT1 class victory in the 24 Hours of Le Mans on June 18, 2006. The 7.0-liter engine also powered the Compuware Corvette C6.R race cars to the 2006 American Le Mans Series manufacturers, drivers and team championships with a perfect reliability record.
"Winning this award is another milestone in the history of the legendary GM small-block V-8," said GM Racing director Mark Kent. "The championship-winning LS7.R has evolved to a very high level of development, yet it retains the longstanding virtues of compact size, simplicity, reliability and high specific output that have made the GM small-block V-8 the world's most successful production-based racing engine."
The 2006 Race Engine of the Year Awards were organized by Race Engine Technology magazine. The editors made three nominations in each of four categories: Grand Prix Engine of the Year, Global Motorsport Engine of the Year, North American Race Engine of the Year, and Alternative Power Race Engine of the Year. The magazine then invited votes from 50 key race engine engineers representing the spectrum of motorsports.
"It is doubtful if ever have so many experts voted for a competition engine award," said Race Engine Technology editor Ian Bamsey. "Each of the category winners was a genuine selection by an impressive jury of peers."
The Global Motorsport Engine of the Year award was given to GM engineer Roger Allen, engine manager for Corvette Racing. Herb Fishel, former director of GM Racing, accepted the award on behalf of Allen and GM Racing at the ceremony. The Corvette Racing program was conceived in 1996 under Fishel's guidance.
"Winning this prestigious award spotlights the technical expertise of GM Racing and the world-class team of partners and suppliers who have contributed so much to the success of the LS7.R engine," said Allen. "Winning at Le Mans, winning the ALMS championships, and winning this award are all tributes to the teamwork of Pratt & Miller Engineering, Katech Engine Development, and all of the LS7.R component suppliers. On a personal level, it's an honor for me as an engineer to have designed engines that have won the Daytona 500, Indianapolis 500, Daytona 24-hour, and the 24 Hours of Le Mans."
The LS7.R is the heir to the GM small-block V-8's winning tradition that began in 1955. The small-block V-8 is the foundation of the hot rod and high-performance industries and the cornerstone of racing series around the world. GM has produced approximately 90 million small-block V-8 engines with a combined output of 27 billion horsepower.
GM Powertrain developed the production 505-horsepower LS7 small-block V-8 that powers the Corvette Z06 supercar using many competition-derived components and design features. The LS7 bristles with race-inspired technology from Corvette Racing, including titanium connecting rods and inlet valves, a dry-sump lubrication system, CNC-ported cylinder heads, a forged steel crankshaft, and a big-bore aluminum block with plate-honed cylinders.
