“They made a business decision not to return in 2013, as they did in 1977 before returning in 2001. We wish them well and hope they again will choose to return to NASCAR at a later date," he said. “Our fans have a passion for cars and emotional connections to particular manufacturers, and that's why in 2013 we will début new race car designs that are modelled after each manufacturer's production cars. This change is a direct result of feedback from our fans, who are the most brand loyal in all of sports.”
In related news on Monday, Penske confirmed that would be buying their 2013 Ford engines from Roush Yates rather than building them in-house, leaving a question mark over the team's 63-person in-house engine shop.
"It's truly an honour to provide Penske Racing with Roush Yates Ford engines,” said Doug Yates, CEO of Roush Yates. “I have always admired Roger Penske as a team owner and a respected businessman in our sport and beyond. I am looking forward to many wins, championships, and other successes in supporting the Penske organisation."
That means that all of the Ford-powered cars in Sprint Cup competition will be provided by the Roush Yates, much as all the main Toyota-powered cars have consolidated engine supply to Toyota Racing Development rather than running separate programmes or developing units in-house, as Joe Gibbs Racing did prior to 2012.
Only the third manufacturer, Chevrolet, still runs multiple programmes - with Hendrick Motorsports and Earnhardt Childress Racing Engines providing units to their respective stables of teams.
