Engine choices are pretty much the same as 1999. Power output hasn't changed, but Pontiac has made the engines quieter. The SE and SLE receive a normally aspirated 3.8-liter V6 engine. It is rated at 205 horsepower and 230 foot-pounds of torque. The SSEi gets a supercharged V6 worth 240 horsepower and 280 foot-pounds of torque.
All cars come with a standard four-speed automatic transmission.
For normal driving, the SE and SLE have plenty of power. But to really outgun cars like the Chrysler 300M and Nissan Maxima, the SSEi's supercharged engine is required. For 2000, traction control is optional on SE and SLE models. It is standard on SSEi models, as is the StabiliTrak system. This system monitors cornering stability.
