It took the Kia Racing program just two seasons and 20 starts to capture Kia Motors America's (KMA) first-ever championships in the 2011 Continental Tire Sports Car Challenge, and today at the Los Angeles Auto Show the company announced a major motorsports expansion for 2012 with two turbocharged Optimas set to enter the Pirelli World Challenge Championships. Continuing KMA's successful partnership with Kinetic Motorsports, the World Challenge Optima SXs will compete in the Grand Touring Sport (GTS) class alongside established nameplates such as Mustang and Camaro at world-class race tracks across North America, including Road Atlanta, the street circuit in Long Beach, Calif., and Infineon Raceway in Sonoma, Calif.
