Opel Tech 1

The Opel Tech 1 Concept was a research vehicle and concept car developed by Opel, which was a subsidiary of General Motors at the time. It was exhibited at the 1981 International Motor Show Germany (IAA) in Frankfurt. The car was based on the fourth-generation Opel Kadett D and used the platform, which was called the T Car. The vehicle was designed by Erhard Schnell^[1] and foreshadowed some of the design aspects found on production Opel/Vauxhall cars released throughout the 1980s.

Body

The design targeted a peak of aerodynamics and reached a drag coefficient of 0.235 c_w thanks in part to a panoramic windshield. Some of the car's aerodynamic features made it into production form on both the 1984 Opel Kadett E and the 1986 Opel Omega – most evidently its front-end styling. The Tech 1's wheel design entered into mass production as an alloy wheel option on top-spec models of the Opel Rekord E2/Vauxhall Carlton. ^[2][3]

Interior

All controls were push buttons; only the steering wheel, gear lever and foot controls were conventional.^[4][5]
