It's very hard to believe, but Brad Keselowski’s 2010 NASCAR Nationwide Series championship is Roger Penske's first NASCAR title of any kind in almost 40 years of trying.

The Penske resume is unsurpassed in other realms of motorsports:

• 15 Indianapolis 500 victories

• 12 IndyCar titles

• Trans Am champion

• Can Am champion

• American Le Mans Series champion

• IROC founder

• Formula One race winner

Many do not realize that Roger was a very successful racing driver before he became one of the most successful car owners of all time. A brief Penske resume:
