Chevrolet to compete in 2012 IndyCar Series with New 2.4L E85 V-6 Engine

Chevrolet will compete in the 2012 IZOD IndyCar Series with a new twin-turbocharged, direct-injected V-6 racing engine powered by E85 ethanol fuel. The new purpose-built Chevy IndyCar engine will be developed jointly by General Motors and Ilmor Engineering.

The Chevrolet IndyCar V-6 will have a displacement of 2.4 liters. The powerplant will have an aluminum block and cylinder heads, and will be a fully stressed chassis member supporting the gearbox and rear suspension. Technical details and specifications will be released at a later date.

Team Penske is the first IndyCar team to commit to Chevrolet power in 2012. The Chevrolet IndyCar engine will be available to all entrants in accordance with the series’ regulations.

Chevrolet competed previously in Indy-style competition as an engine manufacturer in 1986-93 and 2002-05 with V-8 engines, winning 104 races, powering six driver champions, and scoring seven Indianapolis 500 victories.

Re-entering IndyCar racing will help us take our advanced engine technology to the upper bounds of what’s possible. And it will also provide a dynamic training ground for engineers, who’ll transfer the technologies we develop for racing to the products we sell to our customers. GM has become a recognized leader in implementing direct-injection technology in both 4-cylinder and V-6 engines. Building on this foundation, our new partnership with Ilmor will give us even more opportunities to accelerate our advanced propulsion technology strategy. We’ll work to further increase performance, while using the least amount of fuel—and we’ll also learn how to get the most out of E85 ethanol.



Happy days are here again.

When the American auto industry was at it's peak (and oil was not) it participated in many such exciting ventures.

Hard times drove it out, as the return on investment was always questionable.

Now with Uncle Sam's help they are free to do what is exciting.

It is common knowledge that a young engineer can learn much more at the track than in a classroom - I eagerly await GM's participation in tractor pulls.

Let the games begin.


Exciting high noise and high GHG pollution. If those Roman style games were restricted to BEVs, it would be more interesting.


The Romans would have run out of electricity half way through the chariot race and the crowd would show a thumbs down.
