The Pontiac Trans Sport is a minivan marketed by the Pontiac division of General Motors over two generations for model years 1990-1999 along with GM badge engineered variants, the Chevrolet Lumina APV and Oldsmobile Silhouette. Introduced a year before the second-generation Chrysler minivans, the Pontiac Trans Sport and its counterparts marked an industry shift in the minivan segment towards adopting the form factor used by Chrysler. The APV vans shared mechanical commonality with the W platform sedans, along with a unique front-wheel drive, transverse-engine chassis. The Trans Sport was assembled at North Tarrytown Assembly (Tarrytown/Sleepy Hollow, New York), shifting production to Doraville Assembly (Doraville, Georgia) for its second generation. For the 1998 model year, Pontiac renamed the Trans Sport the Pontiac Montana, after an exterior trim package introduced in 1997. Background The Trans Sport and its siblings were created by General Motors to compete with the Chrysler minivans and followed the Chevrolet Astro and GMC Safari, which had used a body-on-frame, rear wheel drive truck platform. Chevrolet and Oldsmobile badge engineered variants of the U-body minivans, with the Lumina APV and Silhouette. In accordance with those brands' images, the Trans Sport was targeted at sport- and style-oriented buyers, while the Lumina and Silhouette targeted the value and premium markets respectively. Concept A Trans Sport concept car was first presented in 1986, featuring futuristic styling, rear gull-wing doors, a built-in Nintendo Entertainment System, and a glass roof. This concept was well-received, and a production Trans Sport was approved in 1987. Most of the concept's more salient features were not translated to the production model, such as the gull-wing doors and glass roof. Chevrolet and Oldsmobile would receive badge engineered variants of the U-body minivans, with the Lumina APV and Silhouette respectively. Technology The Trans Sport, along with the Lumina APV and Silhouette, rode on the U-body platform and was constructed from a galvanized steel space frame, featuring dent and rust resistant polymer plastic body panels on the side and a galvanized steel roof. Similar construction was employed on the Pontiac Fiero, as well as some GM Saturn vehicles. The Trans Sport had three seating options: five-seat (three removable bucket seats in the second row); seven-seat (adding two removable bucket seats in a third row) and six-seat configuration, with two bucket seats per row. Air suspension was offered as an option. The 1994 Trans Sport featured the first powered sliding side door
