In 1993, Rahal-Hogan Racing attempted to continue the Truesports chassis program. It was rebranded the R/H chassis, and quickly scored a second-place finish at Long Beach. The success was short-lived however, as the chassis proved uncompetitive on superspeedways. The team was dealt a massive blow when Rahal failed to qualify at Indianapolis a month later. The following week they switched to the more conventional Lola, while team driver Mike Groff attempted to salvage a season out of the R/H. By the end of the year, the chassis project was abandoned permanently.
