DOVER, Del. -- NASCAR will allow Sprint Cup teams to bring a second car to test fuel injection for the first time on July 7 at Kentucky Motor Speedway with plans to fully implement the new system at the 2012 Daytona 500.
Robin Pemberton, NASCAR's vice president for competition, said at least four organizations are ready to move forward with the Kentucky test.
Teams will also be allowed to test fuel injection during an Oct. 4 and 5 test of the new asphalt at Phoenix. There could potentially be another fuel injection test the Monday after the fall race at Talladega.
Pemberton said NASCAR also would like to test fuel injection on a mile and a half track.
