Chevrolet to Compete in 2012 IndyCar Series with New V-6 Engine

Returns to Open-Wheel Competition as Engine Maker in Partnership with Team Penske

GM Press Release

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

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.

"Indianapolis Motor Speedway has been a proving ground for manufacturers since Louis Chevrolet, our co-founder, first raced here in 1909,” said Chris Perry, vice president of Chevrolet Marketing. “Our return to IndyCar as Chevrolet enters its centennial year is natural. At the same time 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.”

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. The new Chevrolet IndyCar engine program will reunite one of the most successful partnerships in motorsports when Team Penske introduces the Chevrolet engine in 2012. Team Penske previously tallied 31 open-wheel victories with Chevrolet engines, including four Indianapolis 500 wins.

"Our vision is to design, build and sell the world’s best vehicles – and racing is one of the best ways to showcase what we can do," said Tom Stephens, GM vice chairman, Global Product Operations. "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," Stephens said. "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."

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.

"We are excited to have engine manufacturer competition again in the IZOD IndyCar Series, beginning in 2012," said Randy Bernard, CEO, INDYCAR. "Chevrolet brings a strong passion for racing, technology, relevance and innovation, which is a great fit for our new car platform. We are excited about the future of IndyCar racing with the addition of Chevrolet."

2.4 liters - nope.

The twin turbos, direct injection and V-6 parts might become part of the C7 but not at 2.4 liters.

5.5 liter direct injected V-8 w/o turbos is more likely.

 

[njlouc]

Dont get excited!!
I know that I will never live to see an engine like that in a production car. It most likely costs=10corvettes!:W

The number of cylinders means little at that level. Remember the Offenhauser 4 cylinder engines in Indy?? They put out massive power. NOT your typical production 4cyl!!

At our level you cant beat a V8 for real power and torque.
Did someone say affordable??

 

[motorman]

2.4 liters - nope.

The twin turbos, direct injection and V-6 parts might become part of the C7 but not at 2.4 liters.

5.5 liter direct injected V-8 w/o turbos is more likely.

GM stopped the development of the 5.5 TT. DI V-8 is still under the development to be used in pick ups.

Could we be seeing the introduction of the C7 engine??

(snip)

Not a chance.

The new Chevrolet IRL V6 is a purpose-built racing engine designed, engineered and developed for GM by Ilmor Engineering, the same folks which did the Chevy Indy V8s of the mid-80s to early-90s and then, again in the earliy 00s.

It is not related in the slightest bit to any production V6 GM makes or might make in the foreseeable future.

My fearless forecast is that, if there's to be a V6 in the Corvette, it will be a version of the 3.6L DOHC V6 used in the Camaro, the Cadillac CTS and other GM vehicles. For Corvette duty it will have a pair of turbo-superchargers.

It won't be any closer to a production engine than the last "Chevy" engine back in the Cart days.

GM Unveils Corvette Daytona Prototype

The car uses a de-stroked, LS9-based small-block topped with aluminum, CNC-ported cylinder heads. The 5.0L engine produces 530hp @ 7,000 rpm and 450 lb-ft torque @ 5,500 rpm.​

So WTF does the above have to do with this thread's subject, the C7 engine?

I'll let ya figure that 1 out yourself, ur suppose ta be a real sharpie...

This will tarnish the name of Corvette and a complete embarassment to all of us.. absolute garbage. Congradulations GM youve now joined Japan in the worse displacement designs ever. We have freedom for a reason, because we are NOT like other countries, no we are BIGGER and BETTER.

Could I ask what you are talking about?

 

[strokin383-c4]

Could I ask what you are talking about?

The simple fact that they are using anything less than a v-8.

 

[njlouc]

Rob... nice find.

it doesnt matter what the displacement, it's all for marketing.:bash

The Chev team will use V6s and convince the motoring public that the V6 is really better than a V8.

BMW is now using 4cyl in their 528 (full size) sedans. to save gas???

 

[catbert]

The simple fact that they are using anything less than a v-8.

I think the Indy series specs a V/6. There's nothing production about the motor.

 

[Low drag - High speed]

6-Shooter makes a good point ...

... anything new out there could be the C7 engine. At this early date, who can say with any surety what market pressures and legislature fiat will sculpt the final product? An extreme fuel crisis might push all cars towards smaller engines or technology advances might create efficiencies that allow a V16, like that Caddy concept, to be feasible.

Face it, though ... the grannies at GM will stick to the current setup with a front V8/rear transaxle. That's not such a bad thing as long as the styling is exceptional.

 

[Hib Halverson]

The vehicle development cycle for 2014 Corvette is about 4 years and the engine cycle is about the same. Both need to be complete in time for a summer 2013 introduction The car's layout was set a while ago. The powertrain is generally set with only final development left to go. Styling is for the most part complete. I'm thinkin' that what we saw in those Jalopnik renderings of a week or so ago is close to what the car will look like.

V16?
Laughable.
Fuel economy, engine size and weight make it impossible

A 5.5L V8 and/or a 3.6L V6 TT are the likely candidates.

 

[Low drag - High speed]

Well of course not ...

... no one would expect a V16. No need to sneer when musing about cylinder counts. I still doubt the Jalopnik version represents the finality you seem to ascribe it because factories go to great lengths to hide their unreleased designs and often endeavor to feed disinformation to the automotive press. Sometimes a so-called insider is much farther outside than they imagne themselves to be. Regardless of the inflexible, never-changing, undeniably rigid pre-production preparations laid down by the industrial gods, they can pull the wool now and then ....

 

[catbert]

The fuel economy impact of the Vette on the GM CAFE number is insignificant at the low production numbers we are seeing now. Thank God the new Cruze and Sonic are selling well, and the Spark will help too. GM is a hell of a lot more concerned with the truck figures, and their numbers are huge.

Bottom line - V8 only.

Fifth Generation Promises a Leaner and Meaner Small Block

Wixom, MI – A new direct-injection fuel system will help GM’s Gen-V small-block engine deliver greater fuel efficiency compared with the current generation. The fifth-generation small block is an all-new engine family that builds on the architectural and technology legacy of previous generations with greater efficiency, performance and refinement.
