Hitachi will serve as the primary sponsor for nine races – including two doubleheader race weekends – of the Chevrolet-powered No. 3 Team Penske car driven by three-time Indianapolis 500 winner Helio Castroneves during the 2013 IZOD IndyCar Series season.

Hitachi will be the primary sponsor for the season-opening race at St. Petersburg, Fla. (March 24), plus Sao Paulo, Brazil; Detroit (two races); Iowa Speedway, Pocono Raceway; Toronto (two races) and Sonoma, Calif.

Hitachi joined Team Penske for the 2012 season and was the primary sponsor on the No. 2 for several races, including its first victory in the sport with Ryan Briscoe at Sonoma.

"We're very excited to be back with Team Penske in 2013 and we look forward to working with Helio and the No. 3 car team," said Rob Sharpe, Hitachi Automotive Systems Americas, Inc., Vice President of Sales and Marketing. "This valued partnership provides the Hitachi Group with the opportunity to grow our brand globally with a well-respected team built on a tradition of winning and excellence. It also creates great business-to-business and customer networking opportunities at some of the world's premiere racing venues."
