The Ford GT40 is a high-performance mid-engined racing car originally designed and built for and by the Ford Motor Company to compete in 1960s European endurance racing. Its specific impetus was to best Scuderia Ferrari, which had won the prestigious 24 Hours of Le Mans race for six years running from 1960 to 1965. Around 100 cars have been made, mostly as 289 cu in (4.7 L) V8-powered Mk Is, some sold to private teams or as road legal Mk III cars. Racing started in 1964, with Ford winning World Championships categories from 1966 to 1968. The first Le Mans win came in 1966 with three 427 cu in (7.0 L) powered Mk.II prototypes crossing the finish line together, the second in 1967 by a similarly powered highly modified US-built Mk.IV "J-car" prototype. In order to lower ever-higher race top speeds, a rule change from 1968 onwards limited prototypes to 3.0 litre Formula 1 engines; a loophole, however, allowed the private JW "Gulf Oil" team win at Le Mans in 1968 and 1969 running a Mk.I with a 5.0 litre engines.

The Intrepid RM-1 is a sports prototype racing car designed in 1991 by Bob and Bill Riley and built by Pratt & Miller to IMSA GTP specifications. Powered by a Chevrolet V8 engine, it was campaigned variously by Jim Miller, Prototype Technology Group and Wayne Taylor in the IMSA Camel GT from 1991 through 1993. Though it won only one race in its three seasons of competition, the shovel-nosed Intrepid was notable for the extreme—and at one point, disastrous—levels of downforce it generated, giving it the highest cornering speeds of any prototype of its era. The car's development was set back by a devastating 1991 crash at Watkins Glen that critically injured driver Tommy Kendall, and the program never fully recovered.
