Yukon Hybrid


The all-new GMC Terrain crossover SUV delivers segment-best 6.1 L/100 km in highway driving, along with the capability, engineering excellence and refinement that have defined GMC for more than a century. It joins a diverse lineup filled with technologically advanced hybrids, efficient utilities and trucks designed to tackle any worksite task.

A new, 2.4L four-cylinder engine that features direct injection delivers the Terrain's best-in-segment fuel consumption. Reduced fuel consumption is achieved in part with an "ECO" mode that is activated via a console-mounted button. When engaged, it lowers the torque converter lockup speed to help save fuel on models equipped with the 2.4L engine.

A 3.0L DOHC direct injected V-6 engine is also available. Both engines are mated to efficiency-enhancing, six-speed automatic transmissions and offer a refined, confident driving experience. The 2010 Terrain is offered in SLE and SLT trim levels, with high levels of standard and available features, including:

  • Standard rear-vision camera
  • Programmable power rear liftgate
  • Bluetooth hands-free phone capability
  • MultiFlex sliding rear seat that increases passenger comfort or provides optimal cargo space
  • Remote vehicle start
  • USB audio connectivity; MP3 playback
  • 178 mm (seven-inch) touch-screen navigation system and a 40-gigabyte hard drive
  • DVD-based rear-seat entertainment system with two independent screens
  • Standard OnStar and XM Satellite Radio.

From a safety standpoint, the Terrain features four-wheel disc brakes with StabiliTrak electronic stability control and traction control, as well as six standard air bags: dual frontal air bags; head curtain side air bags and pelvic/thorax seat-mounted side air bags. OnStar with one-year Safe and Sound service is also standard.

Here's a look at the rest of the 2010 GMC lineup:


GMC's popular, eight-passenger Acadia continues to win over customers seeking the spaciousness and capability of an SUV with a smooth ride and responsive handling of a crossover. Powered by a direct injected 3.6L V-6, it is offered in SLE and SLT trims. All-wheel drive and SLT-1 and SLT-2 equipment packages are available. A comprehensive safety system includes six standard air bags and standard StabiliTrak electronic stability control system with rollover mitigation technology.

For 2010, Acadia adds available 20-inch chrome-clad wheels, a USB interface for premium radios, OnStar, as well as new exterior and interior colours.


Changes to the rugged yet refined 2010 Canyon pickup include standard head curtain side air bags on all models, three new exterior colours and an expansion of the ZQ8 Sport Suspension package to a greater variety of models and equipment groups.

Sierra 1500

An industry leader in fuel economy, capability and performance, the broad GMC Sierra lineup includes everything from job-ready Work Truck models to the unique combination of performance and luxury that is the Sierra Denali.

For 2010, the Sierra 1500's 4.8L, 5.3L and 6.2L V-8 engines offer E85 capability, while the 4.8L and 5.3L engines now feature variable valve timing. A six-speed automatic transmission is added to regular and extended cab models with the 5.3L V-8 (previously it was offered only on crew cab models); and all 5.3L-equipped models feature a standard 3.08 axle ratio that reduces fuel consumption.

Additional changes for 2010 include side curtain air bags and seat-mounted side air bags made standard on all models, a USB port included on all but base radios, expanded availability of the rearview camera system and two new exterior colours.

Sierra Hybrid

The 2010 GMC Sierra Hybrid carries over as a powerful full-size pickup that achieves 32-percent improvement in city fuel consumption and a 23-percent improvement in overall fuel consumption while delivering the capability expected of a full-size truck - including a 2,767 kg (6,100-pound) towing capacity. It is offered in the crew cab body style on both 2WD and 4WD models.

FlexFuel capability is new for the Sierra Hybrid's 6.0L V-8 engine in 2010.

Sierra 2500HD & 3500HD

Sierra heavy-duty trucks are offered in a range of extremely capable 2500HD (three-quarter-ton) and 3500HD (one-ton) models. They're designed for hauling everything from a construction crew and their equipment to race car trailers, horse trailers and more.

Sierra heavy-duty trucks are available in Work Truck, SLE and SLT trims. The range of configurations - three cab styles, three cargo box styles and five wheelbase lengths - delivers tremendous choice. Some full-size truck manufacturers do not even offer three-quarter-ton or one-ton heavy-duty trucks. Among those that do, the Sierra HD pickups offer many segment-best capabilities, including 8,392 kg (18,500-pound) gross combined vehicle weight rating for vehicles with a gas V-8 and a 5,897 kg (13,000-pound) conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 7,484 kg (16,500 pounds), when equipped with a fifth-wheel hitch.

Changes for 2010 are minor and include a pair of new exterior colours and the inclusion of a USB port on all but the base radio.

Yukon & Yukon XL / Yukon Denali & Yukon XL Denali

The Yukon and Yukon XL family of full-size SUVs continues to offer performance, capability and lowest segment-leading fuel consumption. Yukon Denali models are distinguished with unique exterior design cues, including a signature honeycomb chrome grille. Denali-exclusive headlamps and taillamps further the jewelled look of these special Yukon models.

Changes for 2010 that enhance the lineup's efficiency include variable valve timing on models with the 5.3L engine, as well as Active Fuel Management and a "taller" 3.08 axle ratio on Denali models. Additionally, FlexFuel capability is added to the 5.3L engines.

The Yukon XFE model that was introduced during the 2009 model year returns for 2010. Additional product changes include two new exterior colours, USB ports on the radios and a standard single-speed transfer case on 4WD models. (A two-speed transfer case is optional).

Yukon Hybrid

The GMC Yukon Hybrid broke ground with the world's first production 2-Mode full hybrid propulsion system, which on the 2WD model offers a 34-percent improvement over non-hybrid models. The 2010 lineup now includes the distinctive Yukon Denali Hybrid, which infuses a new level of luxury into the efficient utility vehicle.

The Yukon Denali Hybrid rides on unique 559 mm (22-inch), eight-spoke, flangeless chrome wheels that make a stylish Denali appearance statement. Inside, designers filled the cabin with luxurious amenities such as standard 12-way power, heated/cooled leather-appointed perforated front seating and heated, second-row, leather-appointed bench seating. Buyers may choose an Ebony or Cashmere interior. The only three options on this fully equipped vehicle are a sunroof, rear-seat entertainment DVD system and Side Blind Zone Alert mirrors.

Along with exceptional fuel economy, the Yukon Hybrid and Yukon Denali Hybrid deliver full-size capability - up to 2,636 kg (5,800 pounds) of towing capacity (2WD) and standard eight-passenger seating capacity.
