Corvair, Chevrolet's first compact car, featured a rear-mounted, air-cooled engine like the VW Beetle. Chevy followed the German company's lead further by turning the Corvair into a van and a pickup with the 1963 Chevrolet Corvair 95 Rampside Pickup.
Conversion from a sedan to a van/pickup involved moving the driver seat forward over the front wheels. Total length stayed at 180 inches, but wheelbase actually shrank from 108 to 95 inches.
In the event of a crash, the driver's feet were dangerously close to front bumper, but behind him was a truck bed 105 inches in length or, in the van, a load deck 114 inches long. The Corvair Greenbrier wagon could be fitted with three rows of seats -- offering the room and versatility of a minivan.
The commercial series was badged "Corvair 95" for its wheelbase. Three models were offered -- Corvan, Loadside, and Rampside. The Corvan was a panel van. The Loadside was a pickup with conventional double-walled box and rear tailgate, while the Rampside added a door on the right side of the bed that folded down to form a ramp.
