With Indy being delayed, lets talk Foyt.

On August 26, 1987, the development team, in the presence of FIA officials, tested the two completed cars on the Ford Stockton test track. Initial tests with the short-tail version of the car resulted in an average speed of 250.919 mph (403.815 km/h), falling close behind the closed-cockpit speed record set by the Mercedes CIII-IV development prototype. As the team went on to adjust the car’s aerodynamics, A. J. Foyt tested the second car (long-tail version). The long-tail version proved to be even more capable than its short-tail sibling and allowed Foyt to attain a top speed of 275 mph (443 km/h) at the flying mile after some practice runs.

The next day, Foyt set a new speed record with the long-tail version, averaging 267.399 mph (430.337 km/h) after flying-mile runs in both directions of the track. The runs made with the now improved short-tail version, shortly after, resulted in a new closed-cockpit speed record of 257.123 mph (413.799 km/h), beating Mercedes’ record by a big margin.^[1]

The Oldsmobile Aerotech was a series of experimental high-speed vehicles manufactured 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 August 27, 1987 at the 7.712-mile (12.411 km) test track near Fort Stockton Texas. Prior to this, on August 26, 1987, the car had posted a top speed over a mile of 267.88 mph (431.10 km/h)…
