The Silhouette arrived in 1990 with a base powertrain consisting of GMs 120-horsepower 3.1-liter V6 and a 3-speed automatic transmission. Inside, seven bucket seats were standard, arranged in a 2-3-2 layout. One of the middle buckets could be deleted as a credit option. For 95, the Silhouette drops the 120-horsepower V6 as its base engine, making the 3.8-liter V6 and 4-speed automatic the sole powertrain.
