2011 GMC Sierra
2011 GMC Sierra
Your biggest challenges call for a truck engineered to the highest standards. That's why GMC Sierra refuses to compromise. We design more efficiency, capability and choice into it, to help you get more out of it. That's why GMC was the first to offer a two-mode hybrid for the best fuel economy of any full-size pickup. It's why Sierra offers the widest selection of V-8 power and up to 10,700 lbs of trailering capacity. You expect these achievements from engineers who never say never. It's why Sierra can finish the jobs that offer trucks start.
33% MORE FUEL EFFICIENT. 100% AHEAD OF THE COMPETITION
Sierra Hybrid is the first two-mode hybrid in a full-size pickup, an accomplishment unmatched by the competition. It takes the best of both gas and electric propulsion to provide you with the most efficient power in a given driving situation. The result is a 33 percent increase in EPA-estimated city fuel economy compared to our most efficient gasoline-only SIerra. better yet, this technology does not sacrifice capability. Sierra Hybrid can handle over 1500 lbs of payload, and offers up to 6100 lbs of conventional trailering capacity.
Variable Value Timing (VVT): The heart of Sierra Hybrid is the 6.0L V-8 VVT that produces 332 horsepower and 367 lb-ft of torque. The secret to this engine's balances power is variable valve timing. This feature helps the engine produce near-peak levels of torque across a wide RPM range. This gives you both responsiveness in city driving and both acceleration for passing and trailering.
The Best Fuel Economy Of Any Full-Size Pickup: At low speeds and light loads, Sierra Hybrid can reduce fuel consumption by shutting off the engine and operating on electric power alone. It can also run on engine power alone, or a combination of both gas and electric. In the city, this technology offers an EPA-estimated 20 mpg. At highway speeds, Sierra uses its 6.0L V-8 VVT engine in either V-4 OR V-8 operation - sometimes with an extra boost of electric power - as conditions warrant. Full V-8 power is available for trailer towing, passing or pulling on a long, steep grade. On the highway, Sierra Hybrid has an EPA-estimated 23 mpg.
Regenerative Braking: During normal stops, regenerative braking uses the motors in the highway transmission as generators to decelerate the vehicle by applying resistance in the motors rather than brake friction. At the same time, the motors are capturing that energy as electricity in the 300-volt battery pack, electricity that is available for the next acceleration cycle.
Active Fuel Management: For maximum fuel economy when you don't need extra power, AFM can deactivate four of the engine's eight cylinders. As the load and your demands increase, the cylinders can reactivate within as little as 20 milliseconds to give you maximum power for trailering and passing.
Proven Battery Power: To give you electric drive system ample power without sacrificing capacity, Sierra Hybrid has a 300-volt battery pack built with Nickel-Metal Hydride (NiMH) technology. It tucks under the rear seat area, out of the way, so your passenger capacity and cargo space are unchanged from other Sierras.
A FRAME ENGINEERED FOR YOUR BIGGEST CHALLENGES
Sierra starts with more than just a frame and suspension. It is built from the belief that control and driver comfort go hand in hand. From its sturdy hydroformed, boxed-rail section chassis to its available automatic locking rear differential, every component is engineered with the strength and capability to help you accomplish more every day.
Boxed For Strength: Sierra's frame is engineered with a hydroformed front section and closed-box side rails for high strength. This construction helps to make the frame more resistant to twisting while carrying heavy loads over uneven roads and gives a solid, stable feel when the pavement is smooth.
Carrying The Load: Sierra's front suspension is a fully independent coil-over shock design that has less mass than a typical torsion-bar system for improved ride quality. The rear suspension is a multi-stage leaf spring that progressively increases its support to match your payload. This helps your Sierra feel stable and secure, no matter how hard it's working.
Confident Driving: The StabiliTrak stability control system helps you stay on your intended path while steering and braking in bad weather or on uneven road surfaces. The system senses when your vehicle is not responding to your steering inputs, then adjusts engine speed and braking pressure to any individual wheel to help maintain traction and steering control.
Braking and Steering: All Sierra models feature four-channel antilock brakes for confident stopping in a variety of conditions. Rack and-pinion steering provides precise performance and an on-center feel. It also offers low-speed assist for easier maneuvering in tight spaces.
Sierra All-Terrain: Sometimes, there aren't any roads where you're going. That's why GMC created Sierra All-Terrain. This package is available on half-ton 2WD or 4WD Extended or Crew Cab models with either the 5.3L V-8 VVT ot 6.2L V-8 VVT and the famed Z71 Off-Road Suspension Package. Sierra All-Terrain also includes Z82 trailering equipment, Rancho Tenneco shocks and an Eaton automatic locking rear differential for off-road control, while the bold chrome grille, special chrome-clad 18-inch aluminum wheels and All-Terrain emblems set it apart from the rest.
POWER WITHOUT COMPROMISE
The Vortec engine family has a well-earned reputation for durability, power and efficiency. These engines use an innovative "vortex technology" that swirls and tumbles the incoming air and fuel mixture for enhanced performance and fuel economy. This technology helps deliver torque, smoothness and efficiency with power to spare.
The Widest Range of V-8 Engines: No other full-size pickup offers a wider range of V-8 gas engines. Depending on the Sierra you choose, Vortec power is available in 4.8L, 5.3L, 6.0L Hybrid and 6.2L displacements, with output that ranges from 302 to 403 hp. This makes it easy to match the engine to the job.
Sierra XFE, The Full-Size Economy Leader: No other competitor can offer over 300 hp with more than an EPA-estimated highway fuel economy of 20 mpg. Sierra XFE surpasses this rating, with EPA-estimated highway fuel economy of 22 mpg, to go up to 572 miles between fill-ups. It means you spend less time at the pump and more time on the road.
Smooth Shifts With Exceptional Control: The 6-speed heavy-duty automatic transmission, standard on all 5.3L and 6.2L V-8 Sierra 1500 Series pickups, has several innovative features for added control and confidence. Driver Shift Control (DSC) lets you select a range of gears to suit variable driving conditions simply by moving the shift lever to "M" and using the convenient tap-up/-down button. Tow/Haul mode raises upshifts points to use more of the engine's power for acceleration, and raises downshift points to use engine braking to slow your Sierra for less noise and harshness. Grade Braking (automatically activated in Tow/Haul mode but disengaged when DSC is activated) senses when you want to slow your Sierra, and if the appropriate conditions are met, implements a Grade Braking shift schedule to help you maintain your desired speed.
Flexfuel Capable: All Sierra V-8 engines, except for the 6.0L Hybrid, are for the 6.0L Hybrid, are engineered to run on E85 ethanol, which is a blend of 15 percent regular gas and 85 percent ethanol.
TRAILERING: READY WILLING AND CAPABLE.
Sierra has the capacity to put other pickups on the trailer. Literally. With the available MAX Trailering Package on Extended and Crew Cab models, Sierra can handle up to 10,700 lbs. It includes features tailored for trailering, from the 6.2L V-8 VVT and automatic locking rear differential, to a frame-mounted hitch, complete trailer wiring harness, engine and transmission oil coolers and a trailer brake controller.
Trailer Weight Rating (Up to 10,700 Pounds): Sierra Hybrid Crew Cab 2WD 5.3L V-8 VVT 6000 lbs (max) trailering capacity. Sierra 1500 Extended cab 2WD 6.2L V-8 VVT 10,700 lbs (max) trailering capcity.
See What's Behind You: The Available Rearview Camera Systems projects images onto the rearview mirror display or onto the available in-dash navigation screen. This makes it easier to maneuver while backing into loading areas, and helps you align your Sierra's hitch with the trailer more easily.
Keep Your Trailer Under Control: The available trailer brake controller is completely integrated with the vehicle's electrical and ABS systems, allowing your trailer's brakes to operate simultaneously with the vehicle's brakes. This system can give you greater control of trailer braking force.
Eaton Automatic Locking Rear Differential: No other competitor in its class offers an available fully automatic locking rear differential for on- or off-road use. When the Eaton Locker senses a difference in speed between left and right rear wheels of approximately 200 rpm, it locks to turn both rear wheels in unison for added traction.
THE POWER OF LEADING BY EXAMPLE
The 403-hp 6.2L V-8 VVT makes Sierra the most powerful 1500 Series Crew Cab in its class. it's standard on Denali and available on Sierra Extended and Crew Cab models. Every aspect of the 6.2L V-8 VVT is engineered for maximum power and durability with advanced design techniques and high-quality materials. The result is exceptional refinement, with power to spare for virtually any driving situation.
Horsepower Meets Reliability: Performance is nothing without reliability. like all Vortec V-8s, the 6.2L V-8 VVT is designed for high strength with low friction. With a high-flowing induction stem, the engine gives you ample reserve power for passing or trailering.
Premium Materials For A Long Life: To keep Sierra performing at its best, it is engineered with premium materials for a long life. Its iridium-tipped spark plugs and transmission fluid are both scheduled to last up to 100,000 miles under normal driving conditions. the advanced coolant has a service life of 5 years or 150,000 miles, whichever comes first.
A Monthly Checkup From OnStar: For advanced onboard engine monitoring and diagnostics capability, all Sierras except WT models have OnStar Vehicle Diagnostics (OVD). With OVD, your Sierra can run through a check of your engine, transmission, antilock brakes and more, and e-mail you the results. You can also ask for a diagnostic check while you're driving.
The Best Coverage In America: Even our coverage is engineered for leadership. the GM 5-Year/100,000-Mile Powertrain Limited Warranty, combined with our 24-hour Roadside Assistance and Courtesy Transportation, gives you the best coverage in America. We stand behind our trucks, so you can drive them with confidence.
