It’s been five years since Chevrolet walked away from the IndyCar circuit. But come 2012, the bow tie brand has plans to re-enter the open-wheel racing series by supplying Penske Racing with a fresh batch of V6 engines.
The powerplant will be an aluminum block, direct-injected 2.4L twin-turboed V6 that will run on E85 fuel. Though the specs and output of the engine have yet to be specified, these specs sound about as hardcore as a V6 can get. The engine will be developed by both GM and Ilmor engineers, and will be available to any interested team in the IndyCar series.
