Sierra Powertrains
Sierra models are powered by an efficient lineup of engines, led by Vortec small-block V-8s. Advanced technologies, such as Active Fuel Management (AFM) and variable valve timing (VVT), optimize performance and efficiency. Three FlexFuel engines are available – and partnered with fuel-saving AFM – giving customers the choice of powering their truck with E85 ethanol, gasoline or a combination of both fuels. Sierra 1500's engine offerings include:
• 4.3L V-6 (LÚ3), rated at 195 hp (145 kW) and 260 lb.-ft. of torque (351Nm).
• 4.8L V-8 (L20), E85-capable with iron block; rated at 302 hp (225 kW) and 305 lb.-ft. of torque (412 Nm).
• 5.3L FlexFuel V-8 (LMG), E85-capable with iron block and Active Fuel Management, rated at 315 hp (235 kW) and 335 lb.-ft. of torque (452 Nm).
• 5.3L FlexFuel V-8 (LC9), E85-capable with aluminum block and Active Fuel Management, rated at 315 hp (235 kW) and 335 lb.-ft. of torque (452 Nm).
• 6.2L V-8 (L9H), with E85 FlexFuel capability, an aluminum block and variable valve timing, rated at 403 hp (300 kW) and 417 lb.-ft. of torque (565 Nm). This engine is available in crew cab and extended cab models and is standard on Sierra Denali.
• The variable valve timing system on Sierra's V-8 engines allows linear delivery of torque, with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement). It also helps reduce exhaust emissions. Because it manages valve overlap at optimum levels, it eliminates the need for an Exhaust Gas Recirculation (EGR) system.
• GM's Active Fuel Management technology increases fuel economy approximately six percent under the federal government's required testing procedure and potentially more in certain real-world driving conditions. AFM temporarily deactivates four of the engine's cylinders under light load conditions and seamlessly reactivates them when full power is required. The transition takes less than 20 milliseconds and is virtually indiscernible.

Sierra chassis and suspension
Built on GM's full-size truck platform, the Sierra incorporates features such as a fully boxed frame – with a hydroformed front section – coil-over-shock front suspension and rack-and-pinion steering. It also has wide front and rear tracks that enhance stability and driving confidence through a more secure road feel.
Sierra is offered with five suspension systems, each tailored to suit specific driving requirements:
• Z83 – Delivers a solid, smooth ride with monotube front shocks and twin-tube rear shocks
• Z85 – Designed for enhanced handling and trailer towing, with monotube front and rear shocks
• Z71 – Delivers enhanced off-road capability; features specific monotube front and rear shocks
• Z60 – Designed for maximum street performance and offered with 20-inch wheels, as well as monotube front and rear shocks
• NHT – Designed for maximum towing capacity; it includes monotube rear shocks, 17-inch wheels and off-road tires, and high-capacity rear springs.
Additional chassis and suspension details include:
• A coil-over-shock front suspension delivers linear handling characteristics on all road surfaces.
• A rack-and-pinion steering system provides precise control and strong on-center feel.
• A Hotchkiss-type rear suspension provides superior isolation and ride with a splayed arrangement for the shock absorbers.
• Four-channel ABS is standard on all models and is linked to the StabiliTrak electronic stability control system to help mitigate the occurrence of rollover events.
• StabiliTrak electronic stability control system is standard on all models and now includes electronic trailer sway control and hill start assist.
• Wide front and rear tracks – 68.1 inches (1,732 mm) front/67 inches (1,702 mm) rear – enhance handling and vehicle stability for a more confident road feel.
• A stiff frame reduces vibrations transmitted to the passenger cabin, while the strength and accuracy of the fully boxed frame also enable precise mounting and tuning of chassis and suspension components.
• Autotrac electronic transfer case is standard on SLE and SLT with 4WD.
• An automatic locking rear differential is standard on XFE, SLT and Denali models and available on Work Truck, SL and SLE models.
• Integrated trailer brake controller is available on all models (except when equipped with the 4.3L engine).
• The Z71 suspension is available on SLE and SLT models. Content includes high-pressure, gas-charged monotube shocks, on/off-road tires, off-road jounce bumpers, front recovery hooks (2WD models), a skid plate and high-capacity air cleaner.

• Standard seat-mounted side-impact air bags for driver and right-front passenger provide thorax and pelvic protection.
• StabiliTrak electronic stability control system helps reduce the risk of rollover crashes by keeping the vehicle in the driver's intended path by applying throttle, braking or a combination of both.
• Available rearview camera system (standard on Denali) is designed to provide the driver with a view of people or objects in the rearward path of the vehicle.
• Últrasonic rear parking assist is standard on Denali.
• Standard high-capacity brake system with four-channel ABS featuring smooth, quiet operation, longer pad life and more resistance to brake pulsation.
• Pretensioners minimize forward movement during a collision, and are standard on the front safety belts. Load-limiting retractors cinch the belt more tightly.
• Tire pressure monitoring system, standard on all models (excludes the spare tire)
• Standard remote keyless entry (RKE) system provides a second function for the red panic button. Drivers can use it to locate their vehicle without sounding the panic alarm.
• Strong body structure to absorb crash energy and provide a protective 'safety cage' around occupants.

OnStar details
OnStar is standard on all Sierra models except Work Truck, where it is optional. It uses GPS and cellular phone technology to automatically call for help in the event of crash. OnStar subscribers also can use the service to be Good Samaritans by sending help to other motorists, and to call for help in other non-crash emergencies.
• OnStar is the leading provider of in-vehicle safety, security and information services in the Únited States and Canada.
• Six months of complimentary OnStar Directions and Connections service with Turn-by-Turn Navigation for easier route guidance when available. The feature is easy to use because all directions are sent to the car by an advisor, without the need to stop. Turn-by-Turn can be cost-effective, since map updates and aftermarket navigation systems are not needed.
• Stolen Vehicle Assistance helps police track the vehicle.

GMC Sierra HD Has Résumé for Any Plowing Job

Fullsize pickup offers unmatched torsion bar suspension and plow prep package

With the white stuff finally falling on cities used to snow-covered roads earlier in the winter, plow-equipped trucks that make up a $20 billion annual industry are coming out to play. Only the GMC Sierra HD pickup offers the flexibility of an adjustable torsion bar front suspension as part of the industry's most-comprehensive plow prep package.

'For plow operators, our torsion bar independent front suspension is a major differentiator,' said Sierra ride and handling engineer Chris Bither. 'Our competitors' beam axles can't match it for traction on uneven surfaces and axle hop reduction.'

Front axle loads of all types were a major consideration when engineers set out to design the current generation of Sierra HD pickups, including 2500 three-quarter-ton and 3500 1-ton models. Torsion bars can be adjusted with a single wrench in just minutes to provide proper wheel alignment when the weight of a plow – as much as 1,000 pounds – is added to the front of the vehicle.

At the rear of the truck, 3-inch-wide asymmetric leaf springs are designed to deliver strong traction and support heavy loads like salt-spreading equipment.

All four-wheel-drive Sierra HDs are available with an optional plow prep package, which includes 10-amp power for back-up and roof emergency lights, a heavy-duty 160-amp alternator (or dual 125-amp units for diesel models), a high-flow front bumper, a forward wiring harness, a trailer brake wiring harness, a skid plate, and a high capacity air cleaner with auxiliary transmission oil cooler, all covered under GMC's standard warranty.

By contrast, a prep package for the Ford Super Duty offers an uprated alternator and heavy duty springs. The Ram's package includes 180-amp alternator and a skid plate. GMC offers the only plow prep package for light-duty pickups.

'Even the smaller details of Sierra were designed with plowing in mind,' added Bither, 'Our optional 17- and 18-inch all-terrain tires were developed for excellent snow traction.' All-terrain tires are available for most Sierra models as a $200 option.

Designing Sierra for serious work didn't come at the expense of handling and comfort.

'Our new trucks hold a plow and sander with very little sag at the wheels,' said Andy Ryder, who owns JAMS Lawn Care in Bangor, Maine, and uses only Sierra HDs in his fleet. 'But Sierra's seat comfort, ride, and handling are what keep us happy. And the power and performance when plowing is awesome.'

Whether equipped with a Duramax 6.6L turbodiesel or a 6.0L gasoline V-8 engine, all four-wheel-drive Sierra HD pickups are rated to handle commercial-size straight and V-type plows, where Sierra 1500 models are recommended for use with personal straight blade plows up to 7.5 feet in width.

Ask a Dealer – Plow Purchasing Tips from Matt Campbell of Varney GMC, Bangor, Maine


2012 GMC Sierra1. First, customers should consider their snow-pushing needs. The more snow, the heavier duty truck that's required. While Ford does not recommend the 2012 F150 for snow plowing, the Sierra 1500 can be used for driveways, and the Sierra HD's torsion arm suspension allows for very heavy plow limits at that end of the market.

2. When thinking about capacity, customers should also consider the type of plow they'll be using. Driveways are best done with a small straight blade. The initial cost for V-type plows is higher, but time is money and for larger jobs with larger trucks, V plows significantly reduce work time so more clients can be serviced.

3. Plow truck buyers must also consider the right optional equipment. All-terrain tires add grip, and a locking rear differential can be a big help in slippery situations. Of course, the plow prep package is a must, and I always like to recommend heated seats.

High-Mileage Sierra Owners Search for Durability Limits

2012 GMC Sierra
Three GMC truck owners combine for 2 million miles and counting2012 GMC Sierra
When a new generation of the GMC Sierra fullsize pickup heads into production, it will have already absorbed hundreds of thousands of miles of hauling, towing, use and abuse testing. It's the kind of durability exam customers in the real world administer for years and even decades.

Tammie Roeber, Dave Cleveland and Don Impson are three of those customers. Together, their trucks represent more than 2 million miles and two-and-a-half decades of proven GMC engineering.

'I signed the papers on my new Sierra 3500HD one-ton pickup in 2006, hitched up a trailer, and have been on the road since,' said Roeber, who has recorded more than 1.2 million miles on the original Duramax diesel engine and Allison transmission in her GMC. Roeber makes a living transporting horses across the eastern Únited States. 'From 30 below zero in Minnesota to 100 degrees in Miami,' she §äid.

'I had two Ford pickups prior to owning my GMC, but I was replacing a transmission every year. If that rate continued, I'd be through my sixth transmission with the miles I've put on the Sierra.' Most of Roeber's miles have been driven pulling trailers, including a 48-foot, 16,000-pound trailer holding as many as nine horses. She maintains her truck religiously, sticking to a 15,000-mile oil change schedule. At her pace, that's just three weeks between service visits.

Among Roeber's favorite features are the truck's engine braking capability – she often encounters 6 percent to 7 percent grades that stretch for miles – that's allowed her four-wheel disc brakes to last longer, as well as the comfortable crew cab. With most of her life lived on the road, the rear seat often doubles as a bed.

Dave Cleveland uses his 2002 Sierra 1500 extended cab to travel from his home near Chicago to trade shows as far away as Florida and Colorado. Between those travels and his daily 60-mile commute, he's accumulated 420,000 miles over the past decade. The truck shares a driveway with his wife's 2010 Sierra.

'This truck runs as good today as the day I bought it,' Cleveland §äid. 'The engine and transmission are original. I haven't even replaced the brake rotors or shocks. Other than a rear pinion gear replacement and regular oil changes, it's just had one major tune-up at 200,000 miles.'

Don Impson, a semi-retired veterinarian in Arkansas, has stretched his miles out longer than the others. He started accumulating his 520,000 miles – mostly by making farm visits tending to animals in a three-county area around his home – when he bought his GMC pickup new in 1986.

'Everyone down around us owns trucks, but no one ever talks about this sort of mileage on one engine,' Impson §äid. In addition to the original engine, his manual transmission still has its original clutch. 'I bought a red and white two-tone truck off the lot because the colors were done wrong for a local construction company, but it's actually become somewhat of a calling card. Everyone knows my truck.'

'In 1995, I bought another GMC ¾-ton pickup truck thinking mine may quit on me,' he continued. 'Man, how wrong I was. The 1995 truck has mostly sat while my '86 continues to get the work done. We're both getting older, but me and the truck may still be hankering to make a cross-country trip and I bet we could make it.'

Customers like these help GMC make advancements in durability by providing real-world test results.

'Customer stories are great to listen to, and they provide useful data for planning new trucks,' said Jim Mikulec, lead development engineer for Sierra Heavy Duty pickups. 'We test our vehicles based on where and how our trucks are used to assure consumer demands are met. Vehicle testing takes us high in the mountains, low in the deserts, colder than -50 degrees in Canada and up past 120 degrees in Arizona. These stories show that our diligence is paying off.'

Mikulec's favorite testing involves driving Sierra 3500HD Duramax diesel trucks up Eisenhower Pass in Colorado with 20,000-pound trailers attached. 'With the inclines and altitude, there's no more demanding place to drive a truck and trailer. It's a task to stay with traffic all the way to the top, and it has been satisfying seeing publications prove that GMC is the leader in that regard.'

In an August 2011 PickupTrucks.com test, a 2012 GMC Sierra 2500HD Diesel ascended Eisenhower Pass, the highest point on the Ú.S. Interstate System, faster than comparable Ford or Ram trucks. It also performed better during the descent with its exhaust brake outperforming its competitors.

'Technology also allows us to get data more quickly than we could in the past,' added Mikulec. 'In today's labs, we can simulate stress tests and various weather changes to help refine frames, suspension components and cooling systems.'

Mikulec's top tip for truck drivers looking to go the distance? 'A truck is like a human body. It needs care, and the best way to ensure it lasts longer is regular preventative maintenance.'
