2017 GMC Sierra 2500HD And 3500HD Pickup Drive Review

2017 GMC Sierra 2500HD And 3500HD Pickup Drive Review
- updated 2017 Sierra 2500HD and 3500HD is the tonier twins of the 2017 Chevrolet Silverado HD trucks, immense towing and hauling abilities, heavy-duty pickup trucks are trickier to evaluate than, a Porsche Boxster

- revised 2017 F-series Super Duty trucks with stronger frames, fresh aluminum bodywork, and a boost up to 925 lb-ft of torque for its Power Stroke turbo-diesel V-8

- GM focused primarily on a new diesel powertrain and the refinement of its big trucks at their working limits

- 360-hp 6.0-liter gasoline V-8 as the base engine in the Sierra HD

- turbo-diesel models in the top-grade Denali trim

- ram-air-style hood scoop adds to the conventional fender well intake to facilitate engine cooling

- 910 lb-ft of torque at 1600 rpm, putting it between the Ford and the 900-lb-ft Ram 3500

- new in form of the aluminum cylinder heads, the forged-steel crankshaft, the pistons, the variable-vane turbocharger, the high-pressure fuel-injection system, and the exhaust system with its accompanying selective catalytic reduction aftertreatment components

- new insulated oil pan for noise reduction

- to be some minor diesel clatter at idle and a powerful growl with the accelerator floored

- calm cabin even with the engine straining under a heavy load

- a 35 percent reduction in tailpipe emissions for the L5P compared with the old Duramax

- Sierra/Silverado HD is generally the lightest and wieldiest pickup in its class

- independent front suspension provides surprising steering feel and precision for a big rig despite the wheel still being slightly offset to the right of the driver’s center

- ride quality of 2500HD models when unladen is largely free of serious shakes and hopping over rough pavement

- 2500s can haul up to 3534 pounds and tow up to 18,100, with 3500s rated at up to 7153 and 23,300 pounds

- GMC’s claim that a 2017 3500HD Duramax towing its maximum load was 40 seconds quicker than before climbing up the SAE’s Davis Dam testing grade

- attaching the maximum weight to the Sierra HD’s bumper-mounted hitch (14,500 pounds for the 2500 and 20,000 for the 3500) does not require the use of an additional weight-distributing attachment

- Maximum fifth-wheel trailer weights are 18,100 pounds for the 2500HD and 23,300 for the 3500HD

- GM further improves the already impressive grade-braking ability of its big rigs, with revised controls for the transmission’s tow/haul setting and greater exhaust braking, both of which can be used separately or together

- Sport mode brings aggressive up and downshifts, shifts remain relatively smooth considering the mammoth forces at play on the truck

- the Sierra HD doesn’t feature a trick trailer-guidance system like the latest Super Duty

- trailer-camera system ($999 for most setups) includes add-on cameras to the exterior side mirrors, the bed ($199 or $499 depending on the model), wireless camera ($349)

- system integrates with the truck’s infotainment touchscreen, allowing for additional rearview perspectives beyond the available backup camera on the tailgate, automatic views of the blind-spot area when turning or changing lanes and assistance with hooking up a fifth-wheel or gooseneck trailer

- 2017 models increases slightly over last year 2500HD Duramax versions start at $44,490, our pickup reached at the $70,000
