The IndyCar circuit consists of multiple, exhilarating races held around the world, and features some of the best open-wheel drivers in racing today. The highlight of each season is the Indianapolis 500, a grueling 200-lap race around the famous 2.5 mile track at speeds greater than 225 miles per hour. Completing it demands precision engineering. Winning demands extreme dedication. Each Ilmor engine is built on performance expertise gained throughout our Indy-winning heritage, and our unparalleled commitment to be the best.

Ilmor's ties to IndyCar run deep—our company was founded to design and build turbocharged engines for the American-based IndyCar series. The partnership between Swiss-born Mario Illien, British native Paul Morgan, and American businessman and racing team owner Roger Penske was first powered by General Motors, and an all new eight cylinder turbocharged Chevrolet engine. In 1986, four-time Indy winner Al Unser became the first to race with the Ilmor-designed engine, and in April 1987 Mario Andretti was the first to secure an Ilmor win. The Ilmor-Chevrolet engine went on to win multiple championships, and rapidly became the dominant engine in Indy racing.

Ilmor later partnered with Mercedes-Benz to produce the MB500I, perhaps the most powerful engine in the nearly 100-year history of the Indy 500. It was driven to victory by famed Indy racer Al Unser, Jr.

From 2003-2011, Ilmor worked in partnership with Honda Performance Development, a partnership that produced well over 150 victories.

In 2012, Ilmor reunited with Chevrolet Racing to develop and race a twin-turbocharged, direct-injected V6 engine for competition in IndyCar. Since then, Chevrolet and Ilmor captured six back to back Manufacturers Championships, and are a dominant force in the series every year.
