Chevrolet Astro
The Chevrolet Astro was a rear-wheel drive minivan introduced by Chevrolet in 1985 to rival domestic (American) competitors the Dodge Caravan/Plymouth Voyager twins and the Japanese Toyota Van. Also sharing the Astro's platform was its sibling, the GMC Safari. In addition to standard passenger uses, the vans were also available as cargo vans, and converters used them as the basis for small conversion vans.
Both Pontiac and GMC have used the Safari nameplate (GMC is part of the Pontiac/GMC division); Pontiac used the nameplate on several of its station wagon models from 1955 through 1989. The two Safaris, both Pontiac and GMC, were on the market together (often sold by the same dealerships) from 1985 through 1989.
The Astro model name had been used previously for the unrelated Chevrolet Astro 1 Concept car, first shown at the New York Auto Show of 1967.
While the Astro was referred to as a minivan, it was sized between the Chevrolet Venture/Lumina APV unibody minivan and the full-size Chevy Van/Express. Similar to the Ford Aerostar, it utilized powertrain components common to GM's other light trucks, yet unlike the trucks the chassis was unibody in structure with a front sub-frame to support the engine and front suspension.
