The Rahal-Hogan R/H-001, originally known as the Truesports 91C and developed into the Truesports 92C, was a CART racing car used in the early 1990s. It was developed and raced by Truesports between 1991 and 1992 and sold to Rahal-Hogan Racing in 1993, notably failing to qualify for the 1993 Indianapolis 500 with defending series champion Bobby Rahal. The car was also used by customer team Robco, a part-time CART entrant, in 1992. The car started in 43 CART races, scoring no wins before the project was ended.
