Cadillac revealed this week the ATS-V.R. race car at the Circuit of the Americas that took place in Austin, Texas, and based on the leaked ATS-V production model, this 600 HP Cadillac ATS-V.R. race car complies with the international FIA GT3 requirements.
The street car had its twin-turbo 3.6 liter V-6, dubbed LF4.R modified and its race engine updated with larger BorgWarner turbochargers, a carbon fiber intake manifold with full high-capacity water-to-air intercooler and a Bosch programmable engine management system. The car’s transmission was replaced with a rear-mounted Xtrac sequential six-speed transaxle with steering wheel-mounted paddles. The traction control system is driver adjustable while the rear end has a limited-slip differential and a 3.13 final drive gear.
The Cadillac race car also has Brembo brakes with 6-piston calipers and 15.0-inch rotors in the front and 4-piston calipers and 14.0-inch rotors in the back. The chassis has a reinforced production unibody with a safety cage designed for racing and a reinforced 8-point welded roll cage. The new car’s fenders were also modified to fit the FIA-mandated tires, which are mounted on BBS wheels that are 12 inches wide up front and 13 inches in the back.
Even if Cadillac did not say on which series it plans to take the ATS-V.R. racing, taking into account that the auto brand is already a competitor in the Pirelli World Challenge with its CTS-V, it is likely that it will continue to participate in that series with its new race car.
