The Corvette C5-R was part of a plan
by General Motors and their Chevrolet brand
to create a factory team to
participate in grand touring races not only in North America, but also
elsewhere in the world, most notably at the 24 Hours of Le Mans. GM had
previously been against approving factory support for Corvette racing programs,
although the IMSA GT Championship's Corvette
GTPs had seen some support until they ended
competition in 1989. With the fifth generation Corvette however, GM chose to
show the performance capabilities of the new car by using a more
production-based racing car instead of the "in-name-only" Corvette
GTP. Their intentions were to take on Dodge and Porsche,
who were already running in the category at the time.
General
Motors
chose the Pratt & Miller group
of Michigan to build and develop
the new racing cars, as well as to organize the racing team in preparation for
a debut in 1999. Riley &
Scott also assisted in the
project, running a second team for a year. Since regulations in place at the
time limited the team to using elements of production Corvettes, Pratt &
Miller and GM used heavily modified road car mules to test out the engine and
other equipment that the racing cars were to use.
Later,
the actual
race chassis were built, sharing only basic key structural elements with the
road cars. A firewall was placed immediately behind the driver's seat in the
cockpit, eliminating any rear visibility inside the car. A large diffuser and
wing were added to the rear, while a splitter and vents on the hood were added
to the front. The front headlights were also replaced with protruding permanent
units in place of the pop-up headlights on the road car.
The
C5-R initially
used a 366 ci (6.0 liter) V8
engine based on the road car's LS1.
This was replaced with a larger
427 ci (7.0 liter) engine several months later during the 1999 season, and
became the standard engine for the C5-R for the rest of its career. Katech
Engine Development constructed the C5-Rs engines, although they retained
elements of the production LS1 units.
