Pirelli World Challenge
With four separate classes of competition (GT, GTS, Touring Car, and Touring Car B-Spec), Pirelli World Challenge is one of North America?s top production car-based championships. Pirelli World Challenge events are a maximum of 50 minutes start to finish, feature standing starts and the world?s most popular manufacturers racing head-to-head. Pirelli World Challenge competition was born in the mid-1980s with the SCCA Endurance Championships, transforming into the Pirelli World Challenge in 1990.
2014 will be Pirelli World Challenge's first competition visit to Barber Motorsports Park, and will feature a double-header event, racing both GT/GTS and TC/TCB on Saturday and Sunday for a total of 4 races throughout the weekend.
Pirelli World Challenge classes:
Grand Touring (GT): The allowed body styles within this class are coupe, sedan and convertible. The cars permitted in GT are typically sold in the market as ?sports?cars, ?sport touring? cars, or performance versions of ?luxury? cars. Forced induction is permitted on cars that come equipped with forced induction stock, or on cars that SCCA Pro Racing has determined need help reaching the target horsepower range. Power output ranges from 425 ? 525 hp. Weight varies depending on power output and tire size. All of the vehicles in GT are rear-wheel drive or all-wheel drive.
Grand Touring Sport (GTS): Cars eligible in GTS are prepared to a level much closer to that of a stock vehicle. Additionally, many FIA GT4 class cars are eligible as well as cars built to the 2008/2009-spec Touring Car regulations until the end of the 2011 season.
Touring Car (TC): The allowed body styles in this class are 2 seat roadsters, coupes, hatchbacks, wagons, sedans. Power output ranges from 230 to 260 hp. Weight varies depending on the power output of the individual drivetrain configurations. Front-wheel, rear-wheel, and all-wheel drive configurations are permitted. Forced induction may be allowed on cars that have forced induction systems available from the manufacturer which do not void the factory warranties.
Touring Car B-Spec (TCB): These are smaller cars with small, efficient, naturally aspirated motors. Modifications are limited to manufacturer specified performance spring and shocks to keep overall cost down. The only modifications allowed are pre-approved suspension kits, other than that no mods of any sort.
