On February 9, 2017, Chevrolet announced the introduction of the purpose-built Camaro GT4.R designed and built to meet the FIA GT4 regulations. The new race car is based on the ZL1 Camaro. We caught up with this new race car in the pits at the 2017 Pirelli World Challenge (PWC) race in St. Petersburg, Florida. Blackdog Racing brought two of them to the track where they will be driven by Tony Gaples and Lawson Aschenbach. The Camaros will compete in the GTS class in PWC. The Camaro is fabricated by Pratt & Miller Engineering and diverges from the normal production car in several ways. The new racer is powered by a naturally aspirated 6.2-liter LT1 V-8 engine. This engine normally produces 460 hp but will be restricted to a yet-to-be-announced lower number, due to pending Balance of Performance (BOP) adjustments. An Xtrac sequential transmission and limited-slip differential put the power to the ground.
The GT4.R comes with adjustable traction control, adjustable Ohlins Racing coilover dampers and adjustable ABS braking system. The Camaro body is festooned with aero enhancements, including an adjustable rear wing, front splitter, and dive planes. The nose panel, hood, doors, and trunk are made of lightweight carbon fiber to reduce weight. The interior has been stripped of all of its production comfort features. It now includes a FIA-approved rollcage, floor mounted pedals, fire suppression system, removable steering wheel fitted with multiple driver aids, and digital driver’s display.
The GT4 category was first developed by the SRO (Stephane Ratel Organization) in 2009 and approved by the FIA. GT4 race cars must be available for purchase for a fixed amount set by the FIA. The original price for a 2009 GT4 race car, including the Callaway Corvette, was 160,000 Euros ($170,000). In 2009, five special GT4 LS3-powered C6 Corvette coupes were built by Callaway Competition in Leingarten, Germany. They dominated the series for several years. These Corvettes are now too old to compete in GT4. The category currently features a diverse range of competitors including Aston Martin, Porsche, McLaren 570S Ginetta G55, Mustangs, and the new Camaro.
Let’s hope this new Camaro kicks butt!
