Oldsmobile's minivan offers the same dimensions as the Chevrolet Venture and Pontiac Montana. All Silhouette models get two sliding passenger doors as standard equipment. Curbside doors on the GLS and Premieree Edition are power-operated, convenient for unloading the munchkins. (In the base GL, the motorized door is an option.)Just one powertrain is available: a 185-horsepower 3.4-liter V6 attached to a four-speed automatic transmission that powers the front wheels. This type of layout is common to all the best-selling minivans. The engine sits in the usual sideways position, which allows maximum use of interior space. Next Page
