As before, the race car and the Z06 will share the same, production-based aluminum frame. However, for the first time, the frames for the race car and production Z06 will be built in-house at the Corvette's Bowling Green, Ky., assembly plant.
By leveraging advanced manufacturing materials - such as laser welding, Flowdrill-machined fasteners and a GM-patented aluminum spot-welding process - the production structure is significantly stronger than its predecessor. For Corvette Racing, this equates to a race chassis for the C7.R that is 40 percent stronger than the outgoing C6.R.
"In the first lap in the C7.R, the drivers felt the increase in chassis stiffness," said Mark Kent, director of Racing for Chevrolet. "The drivers instantly noticed that the C7.R handling was better over changing surface features and rough track segments. This is important as our drivers don't always stay on the smooth pavement, and are constantly driving over curbing at corner apexes."
The addition of direct fuel injection to the Corvette Z06 will enable the technology to return to a Corvette race car for the first time since the end of the GT1 era in 2009. It promises greater efficiency, which can make a significant difference in long-distance endurance racing such as Daytona and Le Mans through fewer time-consuming pit stops.
"Direct injection offers two advantages for the race team," said Kent. "First, it offers drivers more precise throttle control, so that even the smallest changes in the driver's throttle position delivers a proportional response from the engine. Second, direct injection typically improves fuel economy about 3 percent. That could be enough to bypass one fuel stop during a 24-hour race. Given that races are often won and lost in the pits, a 3 percent gain in fuel economy could translate to a significant advantage in track position." << Prev Page 2 of 3 Next >>
