The 2000 Pontiac Bonneville is a five-passenger sports sedan that sits between a mid-size and a full-size car. Three trims are available; the base SE, the mid-range SLE, and the top-of-range SSEi. The SE and SLE are powered by a 3.8L V6 which produces 205 hp and 230 lb-ft of torque. The SSEi adds a supercharger to the 3.8L V6 which boosts output to 240 hp and 280 lb-ft of torque. All three trims use a four-speed automatic transmission.
