The Buick Terraza is a minivan from General Motors' Buick brand that was sold from the 2005 through 2007 model years. It filled the position of GM's luxury minivan that was previously occupied by the Oldsmobile Silhouette until the division's demise in 2004. The Terraza was built alongside its Chevrolet, Pontiac, and Saturn sisters; (Uplander, Montana SV6, and Relay) in Doraville, Georgia. The chrome-trimmed Terraza was the most luxurious and costliest of the GM minivans, starting at US,110 in 2005. The Buick debuted with one engine, a 3.5 L High Value V6 that generates 200 hp (149 kW) and 220 ft-lbf (298 N-m) of torque, going from 0-60 mph in the 9-second range. For 2006, a 3.9 L LZ9 V6, with 240 hp (179 kW) and 240 ft-lbf (332 Nm) torque, was added as an option, which delivered faster acceleration and better response. A flex-fuel version of the 3.9 L V6 also became available for the Terraza's third season. The 2007 Terraza equipped with side airbags scored a "good" in the frontal offset and an "acceptable" in the side impact IIHS crash tests. Year-by-year changes 2005 • Buick introduces the Terraza, its first minivan for the North-American market. The Terraza is available in two trim lines: entry-level CX (FWD or AWD) and top-of-the-line CXL (FWD or AWD). 2006 • The 3.5 L V6 can now be upgraded to a 3.9 L LZ9 V6 engine. Second row side-curtain airbags are now also an option. 2007 • The Terraza's last year, and all-wheel drive models are dropped. The 3.9 L V6 is now the only engine offered, however it is available with a flex-fuel option. More standard features are offered on the new CX Plus model, which is slotted between the CX and CXL. The Terraza was removed from Buick's website in early fall 2007, around the same time it was dropped from Buick's lineup, in anticipation of the new Enclave.
