2011 Sierra 3500HD New Car Test Drive
The GMC Sierra HD line of heavy duty trucks has been reengineered from the ground up for 2011, with a new frame, new front and rear suspensions, bigger brakes, and a new, more powerful Duramax 6.6-liter turbo diesel.
At the same time, a luxurious new Denali model brings premium features and styling to the heavy-duty line. The Sierra Denali HD is a 2500HD Crew Cab with a choice of Vortec 6.0-liter V8 or the Duramax diesel with the latest Allison six-speed automatic.
GMC Sierra heavy-duty pickups are well-suited for real-world use and abuse. They can haul tons of brick and cement and tow the concrete pump, then turn around to be used for a night on the town or grocery shopping while the fifth-wheel's left in camp or the horses are in the corral. If your hauling happens once or twice a year or you tow a bass boat or ski boat, then the 1500-series may be better suited. If your load is heavy, however, or you do a lot of towing, then the Sierra HD is the ticket.
Denali pickups are more luxurious than their namesake environment, with more standard equipment than any Sierra HD, bespoke cabin trim and wheels, and options that include a moonroof, navigation, heated steering wheel, heated and cooled front seats, and on some versions, polished forged alloy 20-inch wheels. This is GMC's answer to Ford's Super Duty King Ranch, Ram's Lariat, and anyone who thinks a pickup should be as relaxing and comfortable as a good lounge. Towing capacity is slightly less than others because of luxury equipment.
The GMC Sierra HD is built on the same chassis as the Chevrolet Silverado HD and shares all the sheetmetal, including the hood, with it. Different hood trim, lights, grille, wheels and ruby red badges distinguish GMC from Chevrolet. GMC buyers are generally younger, more affluent, better educated and choose crew cabs and diesels more than Silverado buyers, which is why the Denali is a GMC.
As with all heavy-duty pickup lines, the Sierra HD offers plenty of configurations with three cab styles, two bed sizes, single or dual-rear wheels and 2WD or 4WD. A 6.0-liter gasoline V8 is standard, rated at 360 horsepower in 2500 models and 322 hp in everything else. It isn't quite as powerful as the competitions' gas engines. However, the 6.6-liter turbodiesel with 765 pound-feet of torque (more than twice the gas engine's) out-rates the 6.7-liter engines on the Ford Super Duty and Ram trucks. GM and Ford use only six-speed automatics in their trucks. Ram uses a five-speed automatic in gas engines and six-speed manual and automatics with their diesel. Sierra HD offers two distinct interior concepts, one bred for work, function and simplicity the other emphasizes luxury and features over outright seating space. Almost anything you can get in a GMC sport-utility is available here, including OnStar, a subwoofer-equipped sound system, rear-seat entertainment, driver memory system, heated leather seats and a moonroof. For the entry price of around $28,000 you get a functional pickup with real load-carrying ability; for big towing in a properly equipped diesel expect to pay $40,000 or more.
The trick in buying the right GMC Sierra HD is to give fair consideration and choose wisely. Compute the permutations among three cabs, two weight classes, two beds, two engine/transmission combinations, two drive systems and four trim levels, and then sort out options that cover everything from a diesel radiator cover to rear park assist, and you can see why prices run from that base $28,000 to well past double it.
The 2011 GMC Sierra HD offers three cabs, two beds, five wheelbases and four trim levels. The Vortec 6.0-liter V8 and six-speed automatic comes standard, the Duramax diesel with a stronger Allison six-speed automatic is available ($8,395).
From the least expensive version, plan on adding $2,000-$3,000 to step up from regular cab to Extended cab, or from there to Crew Cab. Figure $200 more for a long bed version. Add about $3,000 for four-wheel drive.
