The GT4 Camaro will be eligible for the IMSA Continental Tire SportsCar Challenge.
Pratt & Miller has developed the Camaro GT4.R, a turnkey racer eligible for the GTS class of Pirelli World Challenge as well as IMSA’s Continental Tire SportsCar Challenge, which would put it up against the Mustang, Cayman, and others. The car is based on the sixth-generation Camaro platform, and follows on from the successful Z/28.R race version of the iconic American muscle car, which won the 2015 Continental Tire SportsCar Challenge.
The GT4.R, which is developed from the ZL1 version of the streetcar, is powered by a dry-sump race-tuned version of the road car's 6.2-liter V8 engine. Power is driven through an Xtrac sequential gearbox which is operated by a pneumatic paddleshift.
The car also features tunable traction control and an Xtrac limited slip differential, while aerodynamic developments include a new rear wing and front splitter and diveplanes. Other notable features on the GT4.R include two-way adjustable Ohlins Racing coil-over Dampers, adjustable ABS featuring Brembo brakes with six-piston aluminum monobloc calipers in the front.
No price has been announced for the new car but teams are expected to confirm programs imminently.
Chevrolet today introduced the Camaro GT4.R – a new-for-2017 and fully race-ready variant of the sixth-generation Chevrolet Camaro.
Built to global GT4 regulations, the Camaro GT4.R is eligible in the IMSA’s Continental Tire SportsCar Challenge (GS category) and the Pirelli World Challenge (GTS class), two of North America’s top GT racing championships, as well as additional GT4 series across the world.
Developed with technical partner Pratt & Miller Engineering, the Chevrolet Camaro GT4.R is built off the Camaro ZL1 road car platform. The race-tuned, dry-sump 6.2L LT1 V8 small-block engine – developed and validated by Chevrolet Racing – delivers its power through a race proven, six-speed Xtrac sequential transmission with pneumatic paddle shift and adjustable traction control. Other notable features unique to the GT4.R include:
• Xtrac racing limited-slip differential
• Two-Way Adjustable Ohlins Racing Coil-Over Dampers
• Adjustable ABS featuring Brembo brakes with six-piston aluminum monobloc calipers in the front
• Aerodynamic improvements developed in the wind tunnel including a new rear wing, front splitter and front diveplanes.
The racing success of the fifth-generation Camaro gave Chevrolet engineers a head start on creating a turn-key racer in the GT4.R.
From 2010-16, the Camaro GS and Camaro Z/28.R won 55 races, two Manufacturer’s championships and five driving titles in major North American competition. The lessons and experience aided in the design and development of Chevrolet’s latest customer-driven track car.
