The 1988 Oldsmobile Aerotech, an experimental high-speed vehicle incorporating the latest in performance technology, was driven by three-time Indy 500 winner A.J. Foyt to a world closed-course speed record of 257mph (413 km/h). It was powered by a specially-prepared turbo-charged version of the Quad 4 engine. The Aerotech body was designed by GM Design staff and is one of the sleekest vehicles yet developed for a GM car division. The design of the Aerotech includes the capability of adjusting underbody sections to control the distribution of downforce, front to rear.
