The Century's V6 engine provides a crisp, authoritative response. What is even more impressive about this engine is that, in addition to providing plenty of power, it also achieves excellent fuel mileage, with 20 miles per gallon in the city and a whopping 30 miles per gallon on the highway.A keynote of Buick's heritage is that the big cars from Flint delivered vigorous performance. The Century delivers this with a 3.1-liter V6 rated at 175 horsepower at 5200 rpm, and 195 pounds-feet of torque at 4000 rpm. Called the 3100, it's a solid and conventional engine, with overhead valves and sequential-port fuel injection. The 3100's power is delivered through an electronically controlled four-speed automatic transmission. It shifts smoothly, but otherwise its performance is only adequate. Kick -down response is slow when compared with the latest transmissions used in higher-priced vehicles. Electronic traction control, which comes standard, reduces wheel spin for improved control on slippery surfaces. Also standard is an antilock brake system (ABS), which allows the driver to maintain steering control of the car in a panic-braking situation. Century's front suspension is a MacPherson strut design, while its rear suspension is a multi-link independent using a coil-over strut. This setup is tuned for a soft ride when cruising on smooth, straight highways at normal speeds. But while the boulevard ride is traditional for Buick, it results in undistinguished handling in any sort of vigorous maneuvering: The Century leans when driven quickly through corners and it floats and wallows at high speeds over wavy surfaces. The driver feels isolated from the road.
