The first race car (in concept only) fitted with a turbine was in 1955 by a US Air Force group as a hobby project with a turbine loaned them by Boeing and a race car owned by Firestone Tire & Rubber company.<ref>{{cite journal |journal=Popular Science |title=Turbine Drives Retired Racing Car |page=89 |date=June 1955 |url= https://books.google.com/books?id=biYDAAAAMBAJ&q=popular+science+1930&pg=PA89 |access-date=23 July 2018}}</ref> The first race car fitted with a turbine for the goal of actual racing was by Rover and the [[British Racing Motors|BRM]] [[Formula One]] team joined forces to produce the [[Rover-BRM]], a gas turbine powered coupe, which entered the [[1963 24 Hours of Le Mans]], driven by [[Graham Hill]] and [[Richie Ginther]]. It averaged {{convert|107.8|mph|km/h|abbr=on}} and had a top speed of {{convert|142|mph|km/h|abbr=on}}. American Ray Heppenstall joined Howmet Corporation and McKee Engineering together to develop their own gas turbine sports car in 1968, the [[Howmet TX]], which ran several American and European events, including two wins, and also participated in the [[1968 24 Hours of Le Mans]]. The cars used [[Continental Motors Company|Continental]] gas turbines, which eventually set six [[Fédération Internationale de l'Automobile|FIA]] land speed records for turbine-powered cars.<ref>{{cite web|url= http://website.lineone.net/~pete.stowe/pete_howmet.htm |title=The history of the Howmet TX turbine car of 1968, still the world's only turbine powered race winner |publisher=Pete Stowe Motorsport History |date=June 2006 |access-date=2008-01-31 |url-status=dead |archive-url= https://web.archive.org/web/20080302012133/http://website.lineone.net/~pete.stowe/pete_howmet.htm |archive-date=2 March 2008}}</ref>

For [[open wheel racing]], 1967's revolutionary [[STP-Paxton Turbocar]] fielded by racing and entrepreneurial legend [[Andy Granatelli]] and driven by [[Parnelli Jones]] nearly won the [[Indianapolis 500]]; the [[Pratt & Whitney PT6|Pratt & Whitney ST6B-62]] powered turbine car was almost a lap ahead of the second place car when a gearbox bearing failed just three laps from the finish line. The next year the STP [[Lotus 56]] turbine car won the Indianapolis 500 pole position even though new rules restricted the air intake dramatically. In 1971 [[Team Lotus]] principal [[Colin Chapman]] introduced the [[Lotus 56| Lotus 56B]] F1 car, powered by a [[Pratt & Whitney PT6|Pratt & Whitney STN 6/76]] gas turbine. Chapman had a reputation of building radical championship-winning cars, but had to abandon the project because there were too many problems with [[turbo lag]].
