ALMS: Corvette Unveils New GT Engine

[Blue_Tires]

Corvette Racing’s second-generation C6.R will be powered by a new 5.5L production-based V-8, to compete in the new unified GT class in the 2010 American Le Mans Series as well as the GT2 class at the 24 Hours of Le Mans. The updated C6.R and the Corvette ZR1 on which it’s based represent the strongest link yet between a production Corvette and the modern Corvette Racing team. Both cars are well-equipped to compete on and off the track with showroom competitors including Aston Martins, BMWs, Porsches and Ferraris.

Corvette has a long history of production-based endurance racing, making its first appearance at the 12 Hours of Sebring in 1956, and its first appearance at Le Mans in 1960. Then Corvette chief engineer Zora Arkus-Duntov leveraged the racing program to improve the production Corvette, as evidenced by the development of heavy-duty and high-performance components and the introduction of the race-bred Z06 option on the 1963 Corvette Sting Ray.

The transfer of technology between racing and production cars resumed with the start of the modern Corvette Racing program in 1999. More than a decade later, it’s impossible to imagine one team without the other, according to Tadge Juechter, Corvette chief engineer:

“Simply put, without Corvette Racing, there would not be a Corvette Z06, much less the ZR1. And, without the foundation of the Corvette C6, Z06 and ZR1, the Corvette Racing team would not be the dominant presence in production-based racing.”

1999 – 2004: The C5-R acts as a catalyst for Corvette performance

Corvette Racing campaigned the C5-R from 1999 through the end of the 2004 season. The first-generation car scored 35 victories in 55 races, won its class at the 12 Hours of Sebring three consecutive years, posted three 1-2 finishes in the GTS class at the 24 Hours of Le Mans, and earned four consecutive ALMS manufacturers championships for Chevrolet.

It also served as a catalyst for Corvette performance.

In 1999, the fifth-generation Corvette C5 produced 345 horsepower from its 5.7L V-8. Leveraging the powertrain technologies developed for the C5R, Corvette brought back the hallowed Z06 moniker in 2001, packing a 385 horsepower 5.7L V-8.
