The Buick Terraza is a four-door minivan marketed by Buick from the 2005 to 2007 model years as a luxury crossover sport van. As Buick's first minivan for the North American market, it was a badge-engineered variant of the Chevrolet, Pontiac, and Saturn minivans sharing the U platform, all manufactured in Doraville, Georgia.
The Terraza retailed at US$28,110 in 2005 (), and debuted with one engine, a 3.5 L High Value V6 generating 200 hp (149 kW) and 220 lb÷ft (298 N÷m) of torque. For 2006, a 3.9 L LZ9 V6, with 240 hp (179 kW) and 240 lb÷ft (332 Nm) torque became available; the 3.5 L engine was discontinued a year later. The Terraza offered leather seats and faux wood trim on the steering wheel, instrument panel, and gear shift knob.
Borrowing a design feature from the Rendezvous, all 2005âÂÂ2006 Terraza models featured an independent short-and-long-arm rear suspension with aluminum crossmember and control arms, regardless of drivetrain. The independent rear suspension was replaced with a beam axle for 2007.
The 2007 Terraza equipped with side airbags scored a "good" in the frontal offset and an "acceptable" in the side impact Insurance Institute for Highway Safety (IIHS) crash tests.
