2010 GMC Sierra 1500

2010 GMC Sierra 1500 is alongside the nearly identical Chevrolet Silverado. The Sierra’s wide, tall grille is its hallmark, with big GMC lettering inside; the boxy flares around its fenders are subtle reminders that this is the same brand that sells the extreme-looking 2010 Terrain crossover.

Inside the Sierra’s cabin, some models have a simple, upright design with larger controls and door handles-better suited for work duty-while pricey versions have an interior that would fit in a luxury sedan. The upgraded instrument panel has a smoother, lower design, as well as surfaces and materials that come together nicely.

The 2010 GMC Sierra Hybrid is more of the same; unless it’s fitted with the optional hybrid decal package and the hybrid LCD readouts, observers will likely not notice it as different from a standard Sierra pickup. The 2010 model year brings only minor changes to the Sierra, including revised interior door panels.

2010 GMC Sierra 1500 offer some powertrains option, There’s also a flex-fuel 5.3-liter V-8 with 315 hp and cylinder deactivation for improved fuel economy, which is standard in XFE models and available in other versions. The most expensive Sierra pickups get a 6.2-liter, 403-hp, flex-fuel V-8 that also shows up in the swank Cadillac Escalade. The 5.3-liter as it has plenty of power for most needs without much lower fuel economy than the base V-6. The base V-6 and base V-8 are teamed with a four-speed automatic; all other versions have a six-speed automatic that shifts very smoothly, helps achieve better fuel economy, and cuts down on noise. The Sierra gets up to 15/22 mpg in the XFE edition, falling to only 12/19 mpg in loaded versions.

2011 GMC Sierra Denali 3500HD

Considering that GMC’s Denali line has been known for truck luxury since 1999, now General Motors announced it was expanding its Denali line to include heavy-duty GMC pickups.

The new Denali version: Add chrome, offer Denali-unique wheels and tires, and Denali-specific interior cues, and, in some cases, make a larger-displacement, higher-horsepower engine standard. Look at the Yukon and Yukon XL Denali. In addition to the Denali styling upgrades, that trim level is the only one where you can get the 403-horsepower, 6.2-liter V-8.

The Denali package is available on 3/4- and one-ton heavy-duty trucks, crew cab only, with either rear- or four-wheel drive. Denalis come with the standard (6.5-foot, 2500HD) or long (8.0-foot, 3500HD) bed.

2011 GMC Sierra Denali 3500HD unlike the other vehicles offered with the Denali package, the Sierra HDs come with the same engine/transmission pairings; the 6.0-liter V-8 and 6L90 six-speed automatic transmission is standard, and the 397-horsepower, 765-pound-foot 6.6-liter Duramax turbodiesel V-8 and Allison 1000 six-speed automatic are an $8395 option.

2010 GMC Sierra HD Concept

The GMC Sierra HD was reworked for 2011 with the addition of an all-new chassis and an upgraded 6.6-liter Duramax diesel engine. But while the capable trucks’ guts were given a transplant, the vehicle’s blue-collar exterior and aging interior were left unchanged.

GM have said that we can expect a Sierra HD Concept at the North American International Auto Show in January. The super-sized concept will likely show one possible design direction for the haul-happy pickup, giving it new sheetmetal to accompany its already very capable hardware. To information detail wait until January to find out.!

2010 GMC Sierra Hybrid Crew Cab

GMC Sierra Hybrid Crew Cab is a powerful full-size pickup that achieves 40-percent greater city fuel economy and a 25-percent improvement in overall fuel economy while delivering the capability expected of a full-size truck – including a 6,100-pound (2,767 kg) towing capacity.

Thanks to the two-mode hybrid system and a powerful 6.0L gas V-8, the Sierra Hybrid delivers highly efficient performance, including all-electric driving up to 30 mph (48 km/h). Sierra Hybrid will deliver fuel economy that is expected to be the best in the full-size pickup segment, exceeding the current mileage leader – the non-hybrid Sierra.

It will be offered in the Crew Cab body style on both 2WD and 4WD models. Each model is equipped with several standard, popular features, including StabiliTrak electronic stability control system, a locking rear axle and a trailering package. Sierra Hybrid also offers dual-stage frontal air bags and head curtain side air bags.

The Sierra Hybrid’s fuel-saving performance is derived from GM’s advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM’s hybrid technology system not only enables the Sierra to launch and drive up to 30 mph on electricity alone, it also allows the Vortec 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.

Contributors to the quiet driving experience include:

• New exhaust system and resonator tuned for the 6.0L engine’s Active Fuel Management operation
• Additional engine intake induction tuning for reduced interior noise and pleasing sound quality
• Low-rolling resistance, “quiet-tuned” P265/65R18 tires for reduced road noise
• Electrically driven 300-volt air conditioning compressor reduces vibration and allows the standard, tri-zone HVAC system to cool the passenger compartment even when the gasoline engine is shut off
• Electrically driven 42-volt variable-assist power steering reduces vibration and provides up to a 0.5-mpg fuel economy improvement by reducing parasitic losses common in belt-driven hydraulic systems
• Energy Storage System (ESS) cooling system internal fan is tuned to be quiet at low vehicle speeds when the fan could more easily be heard by the occupants.

In addition, GMC Sierra Hybrid Crew Cab support by EVT, which is always provides abundant torque at all rpm levels for easy towing. t is particularly helpful on grades, as the EVT’s greater ratio spread allows the engine to hold optimal rpm for smooth, steady performance, with no hunting between higher and lower gears. The EVT incorporates grade braking and tap up/tap.

2011 GMC Acadia Denali

Huge Truck, Disappointing Rear Legroom

The heavy duty truck wars are heating up, and until recently the Ford Super Duties have been the only place for luxury truck buyers to go. The Denali nameplate already exists in the GMC showroom on the half ton Sierra. The Denali HD is more of a trim package then a complete package. The front and rear bumpers are painted , while the upper and lower grilles are finished in signature Denali chrome. You can only get the Denali HD in three colors: black, silver and white. Overall, the Denali trim is a very nice looking package on an already good looking truck.
The interior of the Denali HD is similar to any other loaded up GMC Sierra. This seems out of place on a truck of this price. This truck would not fall into that category.

The RAM Heavy Duty is the only one of the three heavy duty trucks that does not use Urea injection in the exhaust system. Driving the Denali HD was an enjoyable experience. The steering was light, with decent on center feel for a truck of this size. With an as tested sticker price of $58,199, is the new Denali HD king of the luxury trucks? The Denali HD is a very understated type of luxury, while the new Super Duty King Ranch is a very in your face, larger-than-life luxury. Between the terrific powertrain and great looks, this new Denali HD really does turn heads.
GMC Acadia Denali Styling

Like Denali versions of the full-size Yukon SUV and the big Sierra pickup truck, this top-end GMC Acadia Denali is highlighted by distinctive Denali design elements. Front-door step-in height is a relatively low 18.9 inches; rear door, 19.8 inches. GMC Acadia Denali Power


All models, including the Acadia Denali, hold a 3.6-liter VVT (variable valve timing) V-6 engine with gasoline direct injection, generating 288 horsepower and 270 pound-feet of torque, driving a six-speed automatic transmission. With front-wheel drive, the Acadia Denali earns an estimate from the Environmental Protection Agency (EPA) of 17 mpg in city driving and 24 mpg on the highway. Special Denali design features include unique lower fascias (front and rear), body-colored lower cladding and rocker moldings, body-color rear fascia and fender flares, and dual chrome exhaust tips. Distinctive bodyside moldings have chrome accents and Denali badging. The Acadia Denali rides on two-tone, chrome-clad, six-spoke 20-inch wheels, versus 18- or 19-inch tires for other Acadias. GMC Acadia Denali Interior

Perforated leather upholstery features matching leather door-panel trim. Heated/cooled driver and front passenger seats are standard. The Acadia Denali's Dual SkyScape sunroof includes a sliding front panel and a fixed rear section.

GMC Denali XT Concept, 2008

GMC Denali XT Concept, 2008

It offers a 50-percent increase in combined fuel economy over comparable small pickup trucks when running on gasoline, and it incorporates a new, muscular form in a performance-styled, hybrid sport-utility truck (SUT).

The Denali XT has a unibody architecture and rear-wheel drive, enabling its distinctive design and efficient performance. It builds on the equity of the Denali line and its reputation for advanced engineering and refinement, the first combination of GM's two-mode hybrid system with an E85 ethanol-capable engine. Denali XT's new, more efficient 4.9L version of GM's small-block V-8 features fuel-saving technologies such as direct-injection technology and Active Fuel Management.

The engine is matched with GM's unique two-mode hybrid propulsion system, giving the powerful SUT exceptional fuel economy and uncompromising capability - including all-electric drive at low speeds. It is a powertrain combination that makes the Denali XT perfectly suited to a variety of active lifestyle activities, such as hauling skis and snowboards to the mountain or towing a sport jet boat to the lake.

Design and construction were spearheaded by Holden Design, within the Australian arm of GM's global design and engineering network.

Dramatic design statement

A muscular form and wide, firmly planted stance give the Denali XT a confidently capable road presence. Minimal overhangs, large wheels, sleek headlamps and a low roof profile deliver an aggressive, performance-oriented appearance.

The Denali XT's design includes a new take on GMC's iconic grille, with a prominent, four-bar element in addition to the large, red GMC logo and signature Denali background. Flared fenders accentuate the wide road stance. The stance is also enhanced when the Denali XT is lowered on its air-adjustable suspension, which creates a sleeker appearance that simultaneously improves aerodynamics. Large, bold 23-inch wheels and custom Kuhmo tires complement the Denali XT's stance.

The Inside

The Denali XT blends mechanical functionality with leather-trimmed comfort.

Billet-metal surrounds, controls and instruments convey the cold precision of an aircraft cockpit. This is balanced by the warmth of bespoke saddle-leather trimmed seats and other contact surfaces.

Truck capability

With stiffness that is greater than most conventional, body-on-frame trucks, the Denali XT's unibody structure supports a very capable truck platform. It also serves as the mounting point for a four-wheel independent suspension that gives the vehicle its performance feel on the road. The multilink front suspension features a forward-mounted steering rack and dual lower links with ball joints at the outer ends, providing sharp responses to driver input. At the rear, a four-link suspension design uses coil-over shocks and a decoupled stabilizer bar to enhance cornering control, reduce body roll and optimize longitudinal compliance. In short, it's a truck that hauls more than cargo on twisting roads.

The rear cargo area is wide, deep and flat, with no suspension or wheelhouse protrusions; the cargo floor measures 55 inches long (1,397 mm) by 47.5 inches wide (1,206 mm). It all adds up to the space to haul a wide variety of lifestyle accessories.

The Denali XT has an estimated payload capacity of 1,100 pounds (499 kg) and a towing capacity of an estimated 3,500 pounds (1,587 kg). This capability is delivered through unique vehicle and powertrain integration, where the multiple modes of GM's two-mode hybrid system provide towing capability.

New 4.9L SIDI V-8 and two-mode hybrid system

The GM's rear-wheel-drive two-mode hybrid transmission is paired with a smaller-displacement version of the small-block engine. The new V-8 4.9L E85-capable engine powers the Denali XT with an estimated 326 horsepower (243 kW).
It uses direct-injection technology to produce the power of a larger engine, but consumes less fuel and produces lower emissions.

The Denali XT's two-mode hybrid system is partnered with the 4.9L engine and uses an electrically variable transmission to enhance fuel efficiency in city and highway driving. In city driving, all-electric propulsion is used at low speeds; on the highway, fixed-gear operation enables efficient performance even when towing a trailer.

The specific characteristics of the Denali XT allowed the synergistic evolution of GM's small-block V-8 and two-mode hybrid beyond the recently introduced in GM two-mode hybrid products, such as the GMC Yukon Hybrid and Sierra Hybrid. During this optimization process, additional powertrain technologies have been integrated, including Active Thermal Management, which transfers thermal energy from one driveline component to another to improve efficiency; and a high-efficiency axle configuration, which fundamentally reduces the losses normally associated with conventional axle configurations.
