2013 gmc sierra 3500hd engine 6.6 l v8 diesel

When the task at hand calls for more muscle than a conventional full-size truck can handle, it’s time to summon a heavy-duty pickup. In both 3/4-ton and 1-ton configuration, the 2013 GMC Sierra HD delivers the type of power and utility needed for the most demanding jobs and does it while providing commendable levels of comfort. To that end, the 2013 Sierra HD lineup offers an exclusive pair of high-content Denali variants to further broaden appeal. Motivation comes in the form of a gasoline-fueled V8 or a torque-rich turbodiesel. Since rival HD pickups like the Ford F-250/F-350 and Ram 2500/3500 each offer of the most hauling power this side of a Class 8 semi-truck, choosing the right brand ultimately comes down to personal preference.

In base Work Truck form, the 2013 GMC Sierra 2500 has a Manufacturers’ Suggested Retail Price (MSRP) of just over $30,000, with the 3500 series tacking an additional $1,500 to the bottom line. 2500 and 3500 Denali trims come in at around $47,000 and top out close to $64,000.

Driving the Used 2013 GMC Sierra 3500

Thanks to its optional 6.6-liter Duramax turbodiesel V8, we found that towing a 10,000-pound trailer behind the 2013 GMC Sierra 2500 HD posed no challenge of any kind. This optional turbodiesel develops 397 horsepower and 765 lb-ft of torque (more horsepower, less torque than the Ram HD, less horsepower and torque than Ford’s PowerStroke diesel). Despite the difference in power from its main rivals, the Sierra 2500 HD still takes top honors in 5th-wheel and conventional towing, as well as payload figures. The Duramax diesel produces quite a bit of noise, but you wouldn’t know it from inside the cabin. One of our favorite features of the diesel powertrain is the "smart" exhaust-braking. Depending on topography and vehicle speed, the system works by progressively restricting exhaust output to help slow the rig with added compression braking. We tested a number of 2013 GMC Sierra HD trucks, with gasoline and diesel engines, long and short beds, and basic to plush trim levels. We found that each exhibited a taut yet compliant ride, good steering feedback, and suitable braking power.

Interior Comfort

The 2013 GMC Sierra HD Work Truck (WT), SLE and SLT interiors are designed to function seamlessly with a wide range of conventional truck duties. But despite the cabin’s utilitarian intent, most trims come nicely appointed with adequate materials quality and fit and finish. While it lacks the bounty of storage bins and compartments found in the Ram and Ford HD trucks, the 2013 GMC Sierra HD nevertheless has a number of useful storage ideas for everything from laptops to the errant tool. On the luxury front, Denali variants feature a distinctive brushed-aluminum trim, leather upholstery and soft-touch materials on the upper dash.

Exterior Styling

The imposing look of the Sierra 2500 and 3500 HD trucks is set off with a massive 3-bar chrome grille flanked by the nameplate’s signature stacked headlamps. For better engine cooling, the raised power-dome hood incorporates a functional set of louvers. The upscale Denali trim is distinguished by its color-keyed bumpers, 4-bar grille with chrome mesh inserts, and matching lower grille design. If you are on the fence between a half-ton and a 3/4-ton truck, it’s worth noting that the load-in height (distance from the ground to the top of the cargo bed floor) is over five inches taller with the HD version, which makes loading heavy items significantly more strenuous.

Favorite Features

ALLISON 1000 SERIES TRANSMISSION
This robust 6-speed transmission is designed to withstand the extra torque generated by the Duramax turbodiesel while also delivering improved fuel economy. Plus, the Allison 1000 is manufactured by the same company that produces transmissions for the U.S. Army’s M1 Abrams tank.

BI-FUEL SYSTEM
Although compressed natural gas has yet to gain a stronghold in the marketplace, the 2013 Sierra HD lineup embraces this cleaner-burning, domestically-sourced alternative fuel with the newly available bi-fuel system. Though it carries a lofty $11,000 price tag, the bi-fuel system could potentially prove itself financially prudent in the long run, as CNG fuel costs roughly $1.50 per gallon less than diesel or gasoline (depending upon local markets).

Standard Features

GMC Sierra 2500 and 3500 HD models are available in regular cab, extended cab and crew cab body styles as well as four trim levels: Work truck, SLE, SLT or Denali. Standard across the board is all-weather rubber flooring, a 40/20/40 split front bench seat, and a driver information center. SLE models add a CD player, air conditioning, power windows, and driver’s seat adjustment, while SLT trims feature heated front seats, Bluetooth connectivity, and fog lights. Top-level Denali versions include ventilated and 12-way power-adjustable front seats, a Bose premium audio system, and power retractable side mirrors. Occupant safety consists of six airbags, a full complement of electronic stability systems, and OnStar emergency/concierge services.

Factory Options

Given the Sierra’s limited rear visibility, the optional backup camera tops our list of recommended add-ons. Also on the menu is a feature-laden convenience package comprised of power-adjustable pedals, rear sonar proximity sensors designed to help guide you into tight park spots with audible warnings, and a slam-proof EZ-lift and lower tailgate (SLT only). Seeing as the available touch-screen navigation unit is a bit long in the tooth, technophiles who want the latest and greatest in multimedia will be better-off with the F-250’s optional MyFord Touch infotainment system.

Engine & Transmission

Every 2013 GMC Sierra HD features a standard 6.0-liter Vortec V8 with cam-in-block variable valve timing (VVT), which provides more power at high rpm and better fuel efficiency. For jobs requiring a significant amount of power there’s the recently overhauled Duramax turbodiesel that produces an earth-moving 765 lb-ft of torque. As a bonus, the Duramax powerplant is compatible with B20 biodiesel. Like most of today’s clean diesels, nitrous oxide emissions are reduced by means of a Selective Catalyst Reduction after-treatment system, which uses urea-based Diesel Exhaust Fluid (DEF) as a cleaning agent. While the DEF tank needs a refill every 5,000 miles, urea-based solution or AdBlue, as it’s known, is available at most major auto parts retailers.

6.0-liter Vortec V8
360 horsepower @ 5,400 rpm
380 lb-ft of torque @ 4,200 rpm
EPA city/highway fuel economy: NA

6.6-liter turbocharged diesel V8
397 horsepower @ 3,000 rpm
765 lb-ft of torque @ 1,600 rpm
EPA city/highway fuel economy: NA

KBB Vehicle Review and Rating Methodology

Our Expert Ratings come from hours of both driving and number crunching to make sure that you choose the best car for you. We comprehensively experience and analyze every new SUV, car, truck, or minivan for sale in the U.S. and compare it to its competitors. When all that dust settles, we have our ratings.

We require new ratings every time an all-new vehicle or a new generation of an existing vehicle comes out. Additionally, we reassess those ratings when a new-generation vehicle receives a mid-cycle refresh — basically, sprucing up a car in the middle of its product cycle (typically, around the 2-3 years mark) with a minor facelift, often with updates to features and technology.

Rather than pulling random numbers out of the air or off some meaningless checklist, KBB’s editors rank a vehicle to where it belongs in its class. Before any car earns its KBB rating, it must prove itself to be better (or worse) than the other cars it’s competing against as it tries to get you to spend your money buying or leasing.

Our editors drive and live with a given vehicle. We ask all the right questions about the interior, the exterior, the engine and powertrain, the ride and handling, the features, the comfort, and of course, about the price. Does it serve the purpose for which it was built? (Whether that purpose is commuting efficiently to and from work in the city, keeping your family safe, making you feel like you’ve made it to the top — or that you’re on your way — or making you feel like you’ve finally found just the right partner for your lifestyle.)

We take each vehicle we test through the mundane — parking, lane-changing, backing up, cargo space and loading — as well as the essential — acceleration, braking, handling, interior quiet and comfort, build quality, materials quality, reliability.
