Chevrolet- and Honda-powered Dallara DW12 IndyCars cars ran together for the first time on Thursday at Homestead-Miami Speedway to gauge the aerodynamic effects of traffic as engine manufacturing development continues in preparation for the 2012 IZOD IndyCar Series season.
The turbulence side by side was minimal and a good tow was apparent when running behind each other, according to IndyCar vice president of technology Will Phillips. Scott Dixon of Target Chip Ganassi Racing drove Honda's Dallara chassis while Tony Kanaan (Dec. 7) of KV Racing Technology and JR Hildebrand of Panther Racing (Dec. 8) were behind the wheel of the Chevrolet car.
Both engine manufacturers ran the two days without any mechanical issues, and tests continued to determine the optimum weight distribution and oval aero configurations.
Both manufacturers will be on the Sebring International Raceway short course next week.
