"announced today that it will compete in the 2012 IndyCar Series with a new twin-turbo direct-injected V-6 racing engine. The purpose-built Chevy IndyCar V-6, which runs on ethanol, is being jointly development by GM and Ilmor Engineering. Although Team Penske is the first IndyCar team to commit to Chevrolet power (and Roger himself was a driving force behind Chevy&amp;#039;s return to IndyCar racing), series rules dictate that the Chevy V-6, and Honda&amp;#039;s new engine, will be available to all entrants.   Although technical details of the new engine will be released at a late date, we do know the aluminum-block V-6 will have a displacement of up to 2.4 liters, and that it will be a fully stressed chassis member supporting the gearbox and rear suspension. Says Tom Stephens, GM vice chairman, Global Product Operations: &amp;quot;Re-entering IndyCar racing will help us take our advanced engine technology to the upper bounds of what&amp;#039;s possible. And it will also provide a dynamic training ground for engineers, who&amp;#039;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.&amp;quot;   Roger Penske provided some deeper background: &amp;quot;Ilmor was the team to partner with to build the current racing engine. Honda made the decision going into 2012 that if there was going to be a new engine they wanted to do that on their own and not utilize Ilmor, so at that point, being a shareholder of Ilmor, I said let&amp;#039;s go out and look for a world-class manufacturer that might be interested in partnering with Ilmor from a technical standpoint and a support standpoint. We went around to various manufacturers, and Chevrolet showed some interest. They were interested in understanding the rules, and the committee got together with them. My role was to introduce Ilmor to General Motors once again, and we&amp;#039;ve had success with them, and, obviously, committing to running the engine again in our cars over the next several years. That doesn&amp;#039;t mean that other teams won&amp;#039;t have the same opportunity. Ilmor and Chevrolet will design the engine. I&amp;#039;ll get an engine just like everyone else does. It&amp;#039;s the same as it&amp;#039;s been with Honda. (Ilmor) rebuilt this year at least 20 engines that were in the field every weekend. It will be the same transparency that it has been. We just decided that we could help the series, and we had a couple hundred people that needed the jobs. So there was real incentive for us to see Ilmor survive and be in the business, and what a great partner we&amp;#039;ve found.&amp;quot;   Panther Racing CEO John Barnes praised today&amp;#039;s news: &amp;quot;Chevrolet&amp;#039;s announcement today only reinforces the strength and direction of our sport. We also need to take time to recognize the unbelievable support that Honda has given IndyCar Series since becoming the sole engine supplier in 2006. The reliability of their motors and the commitment they have for open-wheel racing and our league is a big reason why our sport is as strong as it currently stands today. Let&amp;#039;s hope that even more engine manufactures take note of where our series is heading and jump on board with Honda and Chevy. Teams, sponsors and fans should be very excited for the future of open-wheel racing and the direction in which we are heading.&amp;quot;   In response to the Chevrolet announcement, Honda Performance Development&amp;#039;s Erik Berkman said: &amp;quot;Although we are certainly proud of HPD&amp;#039;s numerous accomplishments during our tenure as single engine supplier to the Series\u2014including an active and unprecedented streak of five consecutive Indianapolis 500s completed without an engine failure\u2014we have repeatedly and unequivocally expressed our desire for engine competition within the Series, dating even from our first days of sole supply, in 2006. We look forward to renewing our relationship with Chevrolet as competitors on the race track and giving the fans of open-wheel racing a spirited and challenging rivalry.&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
