Concept Car of the Week: Oldsmobile Aerotech (1987)

In late 1984, Oldsmobile management had so much confidence in the potential of its new inline four-cylinder engine Quad 4, that a small team was assigned to the creation of the Aerotech, a research vehicle designed to demonstrate the engine's performance by setting a new world speed record. Ed Welburn, then assistant chief designer, was mostly working on the 1988 Cutlass Supreme but his passion for race cars made him the ideal candidate to be handed the assignment by Oldsmobile 2 studio's chief David North. Inspired by Le Mans racers such as the Porsche 917LH and Jim Hall's Chaparrals, he designed a long, flowing car that immediately seduced design director Chuck Jordan and GM management.

The 29th annual NASCAR Sprint Cup Series Media Tour opens on Monday in the Charlotte, N.C., area. It's a four-day smorgasbord of announcements, team-shop tours, optimistic predictions and the unveiling of new race-car paint schemes, team members and sponsorships.
