The team joined the world of open-wheel racing in December 1991 as Hogan and Bobby Rahal purchased the distressed Patrick Racing CART IndyCar World Series team. The team won the championship in its first try in 1992 with driver Bobby Rahal on the back of four race wins. In late 1992 the team absorbed TrueSports and moved into TrueSports' facility in Ohio and began using TrueSports' proprietary chassis in 1993. However this proved disastrous as Rahal and teammate Mike Groff both failed to qualify for the 1993 Indianapolis 500 in the car. Rahal switched to a Lola chassis for the next race while Groff soldiered on with the RH01 until August.
