2010 GMC Sierra 2500 HD Extended Cab Review

By

For several decades, GMC products represented little more than rebadged versions of their Chevrolet counterparts. Beginning in 2007, GMC began a concerted effort to distinguish itself from its divisional sibling. With the 2010 GMC Sierra HD trucks, GM's engineers have also made a concerted effort to increase the differentiation between the Heavy Duty pickups and their lighter-duty 1500 counterparts. With improvements in refinement, engines and capabilities, the GMC line of trucks are easily a match, and in some cases superior, to their peers from Dodge and Ford.

You'll Like This Car If...

Whether purchasing for commercial construction, agriculture or recreational towing, if your needs are truly "heavy-duty" you'll likely find those needs met with the 2010 GMC Sierra HD, which offers all of the virtues, with few of the vices, normally associated with a "heavy-duty" truck.

You May Not Like This Car If...

The Heavy Duty's principal mission is to haul or tow big and heavy things. If you don't need this sort of vehicle and its "heavy-duty" attributes, you'll probably be happier with something not quite so robust.

What's New for 2010

For 2010, a USB port is added to up level radios, while the newest version of OnStar features long range remote start and traffic probe.

Driving the Sierra 2500 HD Extended Cab

Driving Impressions Given the number of drivetrain, cab and chassis variations in the GMC lineup, it's difficult to provide one set of observations regarding drivability. However, everything GMC's engineering team did to...

enhance the driving experience has worked. A rigid frame, in combination with a wide track and retuned suspension (Z85, standard on 2WD and 4WD models; and Z71, the optional Off-Road suspension), supplies the needed capability without imposing the typical vices of a heavy-duty platform. The ride is composed, handling stable and steering accurate with good on-center feel. With the 6.0-liter gasoline V8, performance might be described as "almost recreational." The Duramax does what diesels do best, pulling a lot of load (up to 13,000 lbs.) in an authoritative manner.

Six-Speed Automatic
This transmission has two overdrive gears to provide relaxed cruising with lower engine speeds and a first gear that's intended to enhance off-the-line response. Of importance to those towing is both Driver Shift Control (tap up and down) and standard Tow/Haul Mode.

Gen-IV 6.0L V8 (Gasoline)
For sheer day-in, day-out driving pleasure the 6.0-liter gasoline V8 is terrific, offering extraordinary response for a vehicle this large.

Interior

With the 2010 GMC Sierra there are two available interiors. The base and mid-level Sierra HD standard interior is all about functionality, with an instrument panel focused on ergonomic ease, specific door panels offering larger door pulls and handles, a specific center console and two glove boxes. The "luxury" interior of the SLT trim level offers a driving environment straight out of a top-of-the-line Yukon. With a distinct instrument design, large center console and other specific trim elements the end result is decidedly upscale.

Exterior

"Upmarket" might be a kiss-of-death descriptive for a heavy-duty pickup, but it will work for the 2010 GMC Sierra HD. The grille is framed by a large chrome or black surround, with the GMC logo as its centerpiece, and is flanked by large headlamps. Corner lights wrap into the flared front fenders, which complement the bulge atop the hood, and there is a sleek profile by virtue of a 57-degree windshield angle. Functionally, large door handles are "grab-style" (for ease of operation while wearing work gloves), doors extend over the rocker panels and, on Extended Cab models, the rear doors open 170 degrees.

Notable Equipment
Standard Equipment

For truck-oriented capability few things beat power; GMC's standard 6.0-liter Gen IV V8 delivers 360 horsepower and 380 lb.-ft. of torque, and a six-speed automatic transmission meshes perfectly with the engine's capability. Standard safety features include seat-belt pretensioners, tire-pressure monitoring and OnStar.

Optional Equipment

For many, selecting the diesel is a no-brainer; GM's Duramax turbo-diesel provides plenty of power and is a lot quieter and smoother than diesels of the past. Those carrying lots of random cargo might better organize it with GM's cargo management system, those living in either excessively cold or warm climates will benefit from remote starting on certain trim levels and those wishing to be entertained will enjoy an enhanced DVD system and CD/MP3 audio. Finally, people who often travel to previously unknown destinations might opt for the available touch-screen navigation system.

Under the Hood

GMC offers two engine choices. Base power is the 6.0-liter gasoline V8 which delivers 360 horsepower and 380 lb.-ft. of torque. Although the EPA doesn't provide a rating for vehicles in this category, past experience suggests GM gasoline engines deliver competitive fuel economy. For those wanting more, the 6.6-liter Duramax provides 365 horsepower and a remarkable 660 lb.-ft. of torque

6.0 liter V8
360 horsepower @ 5400 rpm
380 lb.-ft. of torque @ 4200 rpm

"I have enjoyed this truck thoroughly. It is my second GMC Sierra 1500 SLT model. They have both exceeded my expectations and have proved to be reliable. Repairs are expensive, but I've had few. My previous truck is still going strong with 200,000 on it. My son now has that one and is still getting good service out of it."

"This is my 8th pickup truck and the most reliable and powerful owned to date. Being a Denali tells you it has all the bells and whistles for creature comforts but it is the Duramax engine coupled with the Allison Transmission that sets this truck apart. I pull a flatbed equipment trailer and a dump trailer that worked the 6.0 liter 2500HD very hard. The 2500HD Denali with the Duramax laughs at the load and does it all quietly and with a smooth precision that surprised me even after three years."

"The 09 Sierra is the best made and least-recalled truck in this series. The only item that went bad was the power steering cooler behind the front grille, replaced under warranty, nothing else broke of note."

Cons: "The center console could be better"

Likely to recommend this car? (1-10): 10

"I've driven this truck since it was new. I have had no minor or major maintenance issues whatsoever. I have changed the cooling to the green stuff and did change out the spark plugs at 80,000 because I wanted to change them, not because the truck had any performance issues. Mine has the 6L engine and we pull a 28' trailer on vacations and it does this task very well. It is comfortable to drive long distances in even with 4 adults putting the rear centeris too cosey, but we do it anyway."
