Model Lineup




3.9L V-6 VVT

4-spd auto

Terraza CX, CXL FWD








Not Available



Terraza, Buick’s premium crossover sport van, now features GM’s 3.9L V-6, which features variable valve timing and variable intake technology, standard on all trim levels for 2007. The engine, coupled with the Hydra-Matic 4T65 electronically controlled automatic overdrive transaxle, generates 240 horsepower (179 kW) and 240 lb.-ft. (325 Nm) of torque. A FlexFuel version of the Terraza, capable of running on gasoline, E85 ethanol or a combination of the two, will be available later in the model year.

E85 is an alternative fuel made in the United States from corn and other grain products. E85 fuel produces fewer carbon dioxide emissions than gasoline, while offering at least the same outstanding horsepower and torque as equivalent Vortec gasoline-only engines.

GM is a leader in advancing E85 technology and use. Neary 2 million GM vehicles on the road already are E85-capable. For more information about GM’s FlexFuel vehicles, please visit

Like all Buick models, Terraza also is equipped with OnStar’s Directions & Connections Plan with Turn-by-Turn Navigation. The new service allows OnStar customers to talk to a live advisor, who in turn sends complete step-by-step directions to customers’ vehicle through their OnStar system. Audio directions are then automatically played through the vehicle’s stereo as they are needed, triggered by the OnStar system’s GPS capabilities. This will allow drivers to be led to their destination while keeping their hands on the wheel and eyes on the road.

Additional changes for 2007 include redesigned 17-inch eight-spoke aluminum wheels and three new exterior colors – Light Quartz Metallic, Polar Blue Metallic and Gold Mist Metallic. The AWD and the independent rear suspension versions have been discontinued.

Quiet and responsive

With its ability to carry seven people in quiet comfort along with plenty of cargo, Terraza combines SUV styling and all-weather driving capability with the flexibility required by mid-van customers. Just as Rendezvous and Rainier have done in their respective segments, Terraza provides the Buick attributes of comfort, style, a silent ride and ample power.

Front-wheel drive and traction control are standard on all models. Terraza models also include standard StabiliTrak, GM’s advanced electronic stability control system that helps drivers maintain control during sudden maneuvers or low-traction conditions.

Other standard features include a four-wheel anti-lock disc brake system, 17-inch wheels and tires and a 121-inch (308-cm) wheelbase, giving Terraza a smooth, car-like ride with excellent handling characteristics.

Terraza also benefits from QuietTuning, a comprehensive engineering program throughout the entire vehicle to ensure a silent ride. This includes new engine isolation measures and acoustic treatments within the body structure to give this new crossover sport van one of the quietest interiors in the segment, matching its rich appearance and attention to detail.

Interior splendid, functional

Chrome and wood trim accents lend a premium appearance throughout Terraza’s interior, complementing the precision fit and flowing design of the instrument panel, center console and door panels. Terraza CX has cloth trimmed seats, while the CXL has leather-appointed seats in the first two rows.

Seven-passenger seating is standard, with individual captain’s chairs in both the first- and second-row positions. The second- and third-row seats are both foldable and the third-row seats are removable, giving Terraza a high level of versatility between passenger and cargo space. In addition, an innovative rear cargo and convenience area provides an almost unlimited range of options to secure grocery bags, packages or longer objects.

Other interior features include a front overhead console and overhead rail system with snap-in accessory and storage modules. The rail system neatly integrates the overhead lighting system, and accommodates the rear HVAC, audio controls and rear-seat entertainment system/DVD into a single unit. The available snap-in storage models have wide, flip-open doors, enabling passengers to store loose items such as CDs, DVDs, sunglasses or cell phones.

For physically challenged customers, Terraza is available with a Sit-N-Lift power seat system that provides convenient access to the right-hand second-row seating area. Operated via remote control, the power bucket seat rotates and then extends out of the vehicle before lowering for easy entry and exit.

Safety features

Terraza is engineered to be among the safest vehicles in the mid-van segment, providing outstanding performance in real-world crashes. Notable features include structural enhancements to its frame using high-strength steel. Terraza’s front-end compartment incorporates a large crush zone to preserve interior space, while the engine compartment side frame rails are designed to absorb energy in the event of a frontal impact.

In addition to the available side-impact air bags, Terraza has standard dual-stage driver and front-passenger frontal air bags to provide supplemental protection for front seat passengers. Terraza also is equipped with LATCH (Lower Anchors and top Tethers for CHildren) system anchors for child safety seats in all second-row seats

The OnStar service standard on the 2007 Terraza features dual-mode (analog-digital) equipment and includes enhanced hands-free voice recognition capabilities to provide more intuitive continuous digit dialing and improved voice recognition accuracy. Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands-Free Calling that allows drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception. The service also in cludes General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to the participating 911 centers to help them dispatch the appropriate life-saving personnel and equipment to crash scenes faster.

Entertainment options

Terraza is offered with a wide choice of passenger entertainment features, which can be a welcome addition on long trips while giving owners the ability to interface between the vehicle and one’s home computer or audio/video systems.

The vehicle is available with a rear-seat DVD player with flip-down screen and integrated controls. The DVD unit also provides auxiliary video and audio inputs for video games and camcorders, enabling an “instant replay” of a child’s baseball game, for example.

XM Satellite Radio also is available. With a wide variety of programming, XM has something to excite any driver. Whether you want to be entertained or informed, to laugh, think or sing, XM has the perfect channel for you – coast-to-coast, and in digital-quality sound.

A “tri-mode” entertainment system lets occupants listen to as many as three separate entertainment sources simultaneously – DVD, CD and radio – through the speakers and dual-channel wireless headphones.

Mobile Digital Media Powered by PhatNoise is also available. PhatNoise is a wallet-sized, 40-gigabyte hard drive that installs in the Terraza’s overhead rail system. The system’s capabilities include:

  • Storing and playing back up to 10,000 songs in MP3, WMA or WAV formats
  • Storing and playing up to 40 movies in MPEG format (standard format for movies)
  • Storing and playing a combination of songs and movies
  • The ability to provide the software for playing classic video games
  • A voice-browsing interface – if the driver wants to listen to music, the system tells him or her over the radio speakers the song’s name, allowing the driver to run through a list of stored music using steering wheel buttons
  • Listening to books, magazine or newspaper articles recorded on a PC
  • Allowing simultaneous listening to two entertainment sources
  • Transferring digital camera pictures through a USB port in the PhatNoise cartridge and playing them back on the DVD screen

The PhatNoise system’s hard drive cartridge is easily removable, so it can be connected to a home PC or laptop to download computer files for playback in the Terraza, giving passengers an unprecedented level of entertainment customization.

*Horsepower and torque SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first automaker to begin using this procedure and expects to use it for all newly rated engines in the future .
