The chassis and suspension and steering combine to produce an exceptional blend of ride and handling, and the car projects a secure feeling of stability and solidity. The suspension is composed of MacPherson struts up front and a twist beam axle in the rear. It's not as sophisticated as many setups in this class, but it gets the job done. A precise feel of on-center steering and quickness are attributed to Sunfire's power rack-and-pinion steering. Sunfire's body rigidity provides a ride that's firm, confidence at higher speeds, and quiet. Standard on the GT Coupe are P205/55 performance tires on 16-inch aluminum alloy wheels.

With the 2.4-liter 16-valve Twin Cam engine, the GT Coupe provides comparable power to a Honda Civic or Dodge Neon. It raises the Sunfire's performance from the realm of acceptable to spirited. When equipped with the 2.2-liter engine and standard five-speed transmission, the Sunfire gets an EPA-rated 23 mpg in the city and 33 mph on the highway.

Transmission choices include a 5-speed manual, a 3-speed automatic and a 4-speed automatic. Built by renowned German transmission manufacturer Getrag, the new 5-speed manual gearbox features improved shift feel and a synchronized reverse gear for easier engagement. An improved cable shift linkage aids shifting, while a reverse lockout feature was added for enhanced safety. The new Getrag five-speed is standard on the coupe and sedan and optional on the GT convertible. The 4-speed automatic is available for all models and offers much better gearing than the base 3-speed automatic.

Sunfire comes with disc brakes in front, drum brakes in the rear. An anti-lock braking system (ABS) is standard. New brake components for 2000 are designed to optimize wheel slip control, reduce noise, improve pedal feel and contribute to reduced weight. Overall, it is not as sophisticated as the braking systems found on more expensive cars, and overall braking performance is average.
