Firestone. Each IndyCar Series team receives 35 sets of Firestone Firehawk tires for the month of May to use as they determine for practice, qualifying and the race. Firestone makes two tire staggers of approximately 0.35 and 0.44 of an inch available for Indy.

Team Penske. Excellence is expected for the winningest racing team in Indianapolis 500 history. The team has won 14 times, dating back to Mark Donohue’s victory in 1972. The entrant with the next most victories is Lou Moore, who won five times between 1938-49. Team Penske has also won 14 pole positions at Indianapolis, 10 more than any other entrant.

An all-new Midget racing engine was unveiled May 7 by GM Racing, Chevrolet and United States Auto Club (USAC) team owner Tony Stewart at the Indianapolis Motor Speedway. Designed by GM Racing specifically for the USAC National Midget Car Series, the new purpose-built, four-cylinder Chevrolet racing engine will initially power Tony Stewart Racing (TSR) drivers Tracy Hines and Levi Jones in upcoming events. The new Chevy Midget engine will be available to all USAC competitors through independent engine builders. The new methanol-burning 166ci (2.7-liter) Chevy Midget racing engine produces more than 350 horsepower. The lightweight, in-line four-cylinder engine employs an aluminum block and cylinder head with two valves per cylinder. Per USAC rules, the Chevy Midget engine is equipped with mechanical fuel injection and utilizes an electronic ignition system. The new Chevy powerplant stands out from its competition with an innovative architecture that improves its combustion efficiency, enhances airflow and lowers the center of gravity. Advanced technical resources such as computational fluid dynamics (CFD) and solid 3-D modeling used to design GM production engines were also used to develop the Chevrolet Midget racing engine. The major components that define the Chevrolet Midget engine package – the cylinder block, cylinder head and certain ancillaries – will be available to all USAC competitors. Independent engine builders can then assemble Chevy Midget engines using internal components from their preferred suppliers. Kistler Racing Engines of Fremont, Ohio, supplies the Chevy engines that power the two TSR entries.
