Built on a modified GM Indy Car chassis, the Aerotech was designed by Ed Welburn, now GM's global head of design. The Aerotech is less than 2 feet tall and rides less than an inch from the ground. The car's underbody includes a tunnel carved out to provide added downforce. Underbody sections can be adjusted to tweak the amount and placement of downforce.
GM produced three Aerotechs to prove the capabilities of the company's Quad4 engine. Two were short-tailed (ST) versions and one was long-tailed (LT), the one shown here.
