The Oldsmobile Aerotechs were a series of experimental high-speed vehicles created between 1987 and 1992 incorporating the latest in performance technology with the intention of breaking multiple automobile speed records. The first such car was driven by four-time Indy 500 winner A.J. Foyt to a world closed-course speed record of 257.123 mph (413.788 km/h) on 27 August 1987 at the 7.712-mile (12.411 km) test track near Fort Stockton Texas. Prior to this, on 26 August 1987, the car had posted a top speed over a mile of 267.88 mph (431.10 km/h). The car consisted of a March Indycar single seat chassis enclosed in an extremely efficient aerodynamic body shell. It was powered by a highly turbo-charged version of the 2-litre Oldsmobile Quad 4 engine. The Aerotech body was designed by GM Design staff and was one of the sleekest vehicles ever developed for use on a high speed track. The design of the Aerotech included the capability of adjusting underbody sections to control the distribution of downforce, front to rear. Oldsmobile produced three versions of the original Aerotech to prove the capabilities of the company's Quad 4 engine. Two were short-tailed (ST) versions and one was long-tailed (LT).

Subsequently, between 7 - 15 December 1992, another version of the Aerotech, this time powered by a 4.0 litre Oldsmobile Aurora V8 engine and fitted with lights, broke 47 speed endurance records including the 10000 and 25000 kilometre world speed records. Other national and international speed records ranging from 10 kilometres to 24 hours were accomplished by a team of drivers working 24 hours a day for 8 days. These records were also set at the Fort Stockton test track.
