The 2007 Rainier is a 4-door, 5-passenger sport-utility, available in two trims, the CXL RWD and the CXL AWD.

Upon introduction, the CXL RWD is equipped with a standard 4.2-liter, I6, 291-horsepower engine that achieves 16-mpg in the city and 22-mpg on the highway. The CXL AWD is equipped with a standard 4.2-liter, I6, 291-horsepower engine that achieves 15-mpg in the city and 21-mpg on the highway. A 4-speed automatic transmission with overdrive is standard on both trims.

Rainier shares its basic truck-type design with the Chevrolet TrailBlazer, GMC Envoy, Isuzu Ascender, and Saab 9-7X. It comes only in CXL trim with a standard 6-cyl engine or optional V8. The V8 has GM’s Active Fuel Management cylinder deactivation. A 4-speed automatic is the sole transmission. Rainier offers rear-wheel drive with traction control or all-wheel drive that lacks low-range gearing. ABS and traction/antiskid control are standard. Also included are load-leveling suspension, leather upholstery, dual-zone climate control, and OnStar assistance. Curtain side airbags with rollover deployment are optional. Other options include power-adjustable pedals, heated front seats, navigation system, and DVD entertainment.

The Rainier partly redeemed itself with smooth and strong powertrains, competitive acceleration and a plush, quiet ride. But compared to other competing upscale SUVs, Buick’s entry failed to completely deliver in the important categories of refinement, feature content and handling. For consumers shopping in this segment, we suggest taking a look at more qualified and desirable vehicles, such as the Mercury Mountaineer, Toyota 4Runner or Volkswagen Touareg. Another good option is Buick’s new large crossover SUV, the Enclave.
