GMC presented its substantially freshened 2015 Sierra Heavy Duty pick-up trucks at the 2013 State Fair of Texas last September and developed rather a buzz in the truck world. Plainly, the Heavy Duty Truck War is warming up and will certainly be rather a fight in the years and months to come.
We just recently had our very first opportunity to get behind the wheel of the brand-new 2015 GMC Sierra 2500 and 3500 pick-ups, and we can state they are a strong jump ahead of exactly what they are changing, making up substantial range to and beyond the competitors. Some might whine GMC didn’t go far enough, however you have to consider it was simply 3 brief years ago that GM engineers totally upgraded the sturdy frames and suspensions and provided a brand-new pair of powertrains. The GM engineers have actually developed brand-new trucks that are higher than the amount of these certain enhancements and constructed 2 of the greatest gamers in the section.
The engines bring over, GM engineers have actually done substantial work with throttle and braking response calibration, working to more ideal incorporate the changes coming to a stop, as well as how efficiently braking controls much heavier bed and trailer weights around corners, even when nearing optimal gross combined weight scores. Both StabiliTrak and trailer-sway control are basic on many designs, and a hill-hold function was likewise beneficial on our high hillclimb stop.
In regard to the engines, power scores for both the 6.0-liter V-8 gas engine (360 horsepower/380 pounds-feet of torque) and the Duramax 6.6-liter V-8 turbo-diesel (397 hp/765 pounds-feet of torque) continue to be the exact same however are much better adjusted to obtain as much torque through the four-wheel and two-wheel drivetrains as possible. GM engineers strove to make sure they got as much power as possible to the rear wheels through the transmission at both a standing start and at speed.
GM had a Ram 2500 HD with the high-output Cummins and Ford Super Duty F-250 with the Power Stroke on hand for us to drive up and down a 6 percent grade for back-to-back screening. For our test drive, each truck was geared up with a 10,000-pound trailer with the cruise control set at 55 miles per hour at the top of the hillside (tow/haul engaged, exhaust brake switch– where geared up– to “on” or “complete”).
Exactly what we discovered was that the GM setup held the truck and trailer conveniently at or near a consistent speed with an easy-to-understand setting. The Ram HD’s Smart Brake, although efficient in achieving a comparable outcome, provides numerous more settings and choices. We’ve been a fan of the Smart Brake from its intro, however we believe the GM setup is much easier.
On the uphill climb, throughout side-by-side roll-off starts at 30 miles per hour to 50 and 60 miles per hour, the Duramax was the runaway champ that we’ve discovered it to be our 2011 Heavy-Duty Hurt Locker and Rumble in the Rockies tests. We need to keep in mind that the single greatest information that separated these 3 durable haulers on our casual runs up and down Arizona’s Rye Grade hillclimb was how peaceful the interior of the GM trucks were. How well the engines carried out did not amaze us.
The Duramax has actually constantly been a relatively peaceful engine, particularly when compared with the Power Stroke and Cummins, however with the brand-new GMC taxi structures (all which have more high-strength steel and sound-deadening product in the firewall software than before) and indoor design, the sound levels were the huge surprise of the tow test. We understand lots of enthusiastic towing lovers like the noise their diesels make, however we need to state the insulation assisted turn our long drives through the mountains of Arizona and pull back into Phoenix traffic a far more comfy and enjoyable experience. That’s an advantage numerous purchasers might be uninformed of unless they have a great deal of big-truck towing experience.
Associated to interiors, we should point out GM’s highest-level trim plan– the Denali. The 2015 Denali (provided throughout the crew-cab and double 2500 and 3500 lineup) is a great trim plan, we believe it still falls brief of Ram’s Laramie Longhorn and possibly even Ford’s Super Duty Platinum providings.
One piece we particularly like about the GMC when compared with its Chevrolet sibling, is that numerous of the optional functions on the Silverado HD are conventional devices on a likewise packaged Sierra HD. Similar to the light-duty trucks, you can anticipate GMC designs to bring a somewhat greater cost for a comparable level, however they will certainly consist of more devices. The GMCs will certainly provide 4 different trim plans: the base Sierra, SLE, SLT and the premium Denali.
We got to drive both the SLT and Denali plans and were impressed with the updated product usages and trendy stitching over the dash seams and in the seats. The modified interior, offered in both the Silverado HD and Sierra HD, provides a number of power plug ports, 5 USB plugs as well as a three-prong inverter. These are big enhancements in both the GM light-duty and durable lineups that other makers need to pay attention to.
We’ll be welcoming both the GM sturdy pick-ups to a tow-testing head-to-head obstacle later on this summer season, where we really hope to discover out precisely how well these recently freshened designs compare to the brand new 2015 Ford Super Duty headed our method, as well as the existing King of Beasts champ, the Ram 3500 HD. More screening of the GM HDs and the other competitive pick-ups is on our calendar.
