The Oldsmobile Silhouette is a minivan manufactured by General Motors for model years 1990–2004 over two generations. Production ended when General Motors discontinued its Oldsmobile brand in 2004. GM continued to market badge engineered variants, the Saturn Relay and the Buick Terraza for the MY2005. Background General Motors' first attempt at producing a minivan to compete with the Chrysler minivans, the rear wheel drive, truck-based Chevrolet Astro and its twin, the GMC Safari failed to compete strongly against Chrysler's dominance in the minivan market in the 1980s. The 1990 Oldsmobile Silhouette and its sibling models, sold more successfully than the Astro/Safari predecessors. First shown to the public in 1986, the Pontiac Trans Sport concept car featured futuristic styling, individually removable bucket seats with built-in stereo speakers, a gull-wing rear passenger door and extensive use of glass including a glass-paneled roof. The Trans Sport was approved for production without the gullwing door and the glass roof. Chevrolet and Oldsmobile received production vehicles based on the Trans Sport with the Lumina APV and Silhouette respectively. While the Pontiac Trans Sport was targeted at sport- and style-oriented buyers, the Lumina and Silhouette targeted the value and premium markets respectively. First generation (1990–1996) The first 1990 Oldsmobile Silhouette was manufactured on August 1, 1989. Assembled in General Motors' North Tarrytown Assembly assembly facility, these U platform vans consisted of a galvanized steel space frame wrapped in composite plastic body panels that were impervious to rust and minor dents and dings, a manufacturing technique developed on the Pontiac Fiero and also used extensively on General Motors' Saturn line of vehicles. The Silhouette was available with seating for seven, with the five lightweight () rear seats being individually reconfigurable and removable. In 1994 built-in child seats were added to the option list, which provided the ability to switch two of the rear seats between adult and child seating with the pull of a seat-mounted tab. Included with the level ride package, which utilized a compressor and air-pressurized rear shock absorbers to maintain vehicle height regardless of load, was a control panel and air hose kit that allowed the vehicle to be used to inflate tires, air mattresses, sporting equipment and such. In 1994, a remote-controlled power sliding door feature was added, a General Motors innovation. For the 1994 and 1995 model years, traction control was available with the 3800 engine option.
