The IndyCar series in the US will be a two-engine affair in 2012 when GM Chevrolet joins Honda as engine suppliers to the series. Chevrolet will be offering a 2.4 litre twin-turbocharged direct injection all-aluminium V6 to the series, powered by E85 ethanol. Honda has been the sole supplier since 2006.

“This engine program will be a showcase for the efficient and powerful engine technologies that parallel new Chevrolet vehicles like the Camaro, all-new Cruze compact and Equinox crossover,” said Chris Perry, head of Chevrolet marketing.

The first team to commit to competing in IndyCar using the new Chevrolet engine is Team Penske. All entrants will be open to use the new Chevrolet engine option.
