Effectively replacing three vehicles (the truck-based sport utility Rainier, the Rendezvous crossover and the Terraza minivan), the Buick Enclave delivered seven or eight-passenger comfort. Despite providing more desirable fuel economy and a car-like ride, the Enclave was more than eight inches longer than the Rainier. Added to the premium brands line-up in 2008, the Enclave came with front-wheel drive or an all-wheel drive version. Propulsion for the whole premium crossover line in 2008 is derived from a 275-horsepower, direct-injected 3.6-liter V-6 engine. Minor tweaks to the engine in 2009 allowed a power increase to 288 horsepower. As well as providing sufficient cruising power, the V-6 powerplant is also enough to tow up to 4,500 pounds. Inside, the Enclaves space cabin came standard with seven-passenger seating. An optional bench seat has also been available on the premium crossover. When exploiting the Buick Enclaves maximum cargo space by folding out the back two rows of seating, the Enclave presents up to 115.3 cubic feet of cargo room. The use of QuietTuning engineering allowed the Buick crossover to filter out unwanted noises and vibrations from the passengers riding pleasure. The 2008 Buick Enclave came with a host of high-end standard features including tri-zone climate control, power liftgate and xenon headlights. Bluetooth connectivity was added standard starting in the 2009 model year. For 2013, the Enclave received a minor cosmetic facelift with the adoption of a new grille and LED daytime running lights. Riding on a retuned suspension, the 2013 Buick Enclave also presented drivers some considerable interior enhancements. The redesigned dashboard housed a standard rear camera system and an IntelliLink infotainment system.
