The 1998 Buick Century uses a 3.1-liter V6 engine from GM’s 3100 family, paired with a four-speed automatic transmission.
Engine and powertrain overview
For the 1998 model year, Buick kept the Century on GM’s front-wheel-drive platform with a single, standard V6 powerplant designed for everyday usability. The 3.1-liter V6 delivered smooth performance and reliability suitable for a mid-size sedan of the era.
Below are the core specifications for the engine and drivetrain:
- Engine: 3.1 L V6 (3100 family)
- Configuration: V6, naturally aspirated
- Displacement: 3,100 cubic centimeters
- Horsepower: approximately 160 hp
- Torque: roughly 180–190 lb-ft
- Fuel system: sequential multi-port fuel injection
- Transmission: 4-speed automatic (GM 4T60-E)
- Drivetrain: front-wheel drive
These specifications represent the standard engine package offered on most 1998 Century trims. Some limited-market variations might exist, but the 3.1 L V6 was the core powertrain for that year.
Performance and practical notes
Equipped with the 3.1 L V6, the Century was built for comfortable, steady acceleration and dependable daily driving. The 4-speed automatic transmission complemented the engine’s torque curve, delivering smooth shifts and reasonable fuel economy for a mid-size sedan of the late 1990s. Regular maintenance—such as spark plug changes, coolant checks, and belt/valve care—helped preserve reliability over long service life.
