Penske to run Roush engines
Penske will not build its own engines when it switches to Ford for the 2013 NASCAR Sprint Cup season and will instead get units from Roush Yates. The decision means all Ford's Cup teams will continue to run the same engine programme, a move Toyota also took this season when Joe Gibbs Racing adopted Toyota Racing Development power. Rival Chevrolet continues to run multiple engine programmes, led by Hendrick Motorsports and Earnhardt Childress Racing Engines
