Overview

The new 2004 Buick Rainier offers a level of style, ride, comfort and performance that sets it apart from other mid-size sport utility vehicles.

Rainier comes standard-equipped with a Vortec 4200 inline six-cylinder engine with preliminary ratings of 275 horsepower (205 kw) and 275 lb.-ft. (373 Nm) of torque, providing the power, capability and smoothness of a V-8 combined with the efficiency of a six-cylinder. For even more power and outstanding torque, the 2004 Buick Rainier is also available with an all-aluminum, Vortec 5300 V-8 engine, one of the most popular in GM's stable of dynamic powerplants. The available V-8 broadens Rainier's market appeal, enhancing both its performance and utility. Exclusive to Rainier on GM's short-wheel-base, mid-size SUV architecture, the Vortec 5300 V-8 SFI (sequential fuel injection) engine provides 290 horsepower (216 kw) and 325 lb.-ft. (441 Nm) of torque. The Vortec 5300 V-8 delivers peak torque throughout the operating range to meet or exceed the most demanding load conditions.

Both powerplants are mated to the rugged, electronically controlled, Hydra-Matic 4L60-E four-speed transmission. Renowned for its smooth operation, precise shifting and robust performance throughout a wide range of driving conditions, the 4L60-E is used in both performance sedans and light trucks. Rainier's maximum towing capacity ranges from 6,100 to 6,700 pounds (2,745 to 3,015 kg) depending on which engine and drivetrain components are selected.
