GMC Sierra 3500HD Denali work truck gets turbo-diesel boost

The 2017 GMC Sierra 3500 Heavy Duty work truck in deluxe Denali Crew Cab trim with a long 8-foot truck box and dual rear wheels projects an edgy chrome-clad prow and stocks a massive turbo-diesel V8 pumping segment-leading horsepower plus a 19 percent boost in torque muscle.

The Duramax 6.6-liter V8 direct-injection turbo-diesel engine makes 445 hp at 2800 rpm with torque rising to 910 lb-ft at only 1600 rpm.

The diesel links to a 6-speed electronic automatic Allison 1000 transmission which has a high-tech transmission control module to select gears and engage the torque converter lockup.

GMC offers the Sierra 3500HD Denali truck in rear-motivated 2-wheel-drive or 4-wheel-drive traction.

And that Denali tag -- drawn from the language of Alaska Athabascan people meaning "the High One" of Mt. McKinley, tallest peak on the North America continent -- represents the pinnacle edition of Sierra 3500HD Crew Cab in a leather-bound issue rolling on 17-inch polished aluminum wheels wrapped in LT235/80 all-season or all-terrain tires.

Sierra 3500HD trucks are constructed on fully boxed steel frame rails using high-strength steel.

The suspension -- independent up front with forged steel upper control arms and cast iron lower control arms plus torsion bars in place of springs to facilitate trim height adjustments, and rear semi-elliptic 3-stage multi-leaf springs -- produces a remarkably smooth ride quality.

The power-assisted Hydroboost brake system installs a disc at every wheel with Duralife brake rotors and linkage to a 4-wheel anti-lock brake system and GM's StabiliTrak electronic skid controls plus standard Trailer Sway Control on all models including the dual-rear-wheel 3500HD models.

Electronically integrated cruise control system plus auto grade braking and diesel exhaust braking are included to enhance driving control and reduced brake wear on downhill slopes.

The automatic locking rear differential that's standard issue for 3500HD trucks reacts in milliseconds in low-traction situations to boost safety and driver confidence on slippery-wet, mud-soaked or snow-covered surfaces.

Sierra 3500HD trucks also come with digital steering assist power steering which facilitates compliant handling and maneuvering, increased road-holding ability and greater stability control assistance.

The versatile cargo box on the Sierra 3500HD Denali stretches to 97.8 inches long and features 2-tier loading capability, integrated tie-downs and easy access via the CornerStep rear bumper and EZ Lift-and-Lower tailgate.

The one-ton 3500HD Denali amounts to a massive truck capable of Herculean work tasks.

Size-size, the vehicle has a wheelbase length of 167.6 inches and a nose-to-tailgate overall length of 258.3 inches -- that's more than 21 feet long.

Its curb weight of 8070 pounds translates to four tons with a payload of 4930 pounds and a GVWR (gross vehicle weight ratio) of 13023 pounds.

Trailer towing capacity is also impressive: 20,000 pounds with a ball-type hitch and up to 22,700 pounds with a fifth-wheel or gooseneck hitch.

The Denali grade is easy to spot, thanks to the massive chrome-faced grille with mesh inset and the pair of tow hooks mounted in the low fascia and encased in square-box chrome blocks.

Unique gear for Sierra 3500HD Denali includes projector-style headlamps with LED signature daytime running lights. Polished stainless steel exhaust outlet, body-color front and rear bumpers, chrome-lined assist steps, heated and cooled leather front bucket seats, a heated steering wheel and power sliding rear window with defogger, MyLink connectivity with 8-inch customizable touchscreen and a Bose premium audio kit.

Denali grade safety devices standard includes a Rear Vision camera system plus GMC's Driver Alert Package which installs electronic safety gear such as Lane Departure Warning, Forward Collision Alert, Safety Alert Seat and Front/Rear Park Assist.

The bottom line: GMC's 2017 Sierra 3500HD Denali truck comes with an estimated MSRP figure of $59,130.
