2020 GMC Sierra 2500 HD and 3500 HD spied on public roads

We saw spy shots of the Chevrolet Silverado HD a short time ago, and now it looks like GM has got the 2020 GMC Sierra Heavy Duty trucks running around in public too. The one we're looking at here appears to be a 2500 Denali Crew Cab, distinguished easily by the same Denali grille on the 2019 Sierra 1500. Aesthetic differences between the front fascias on the 1500 and 2500 HD are small, but the 2500 is a bit more muscular in the hood and lower trim treatment. GMC doesn't look like it's hiding a whole lot with this camouflage, since the sheets over the grille and headlights are mostly transparent. The black tarp over what appears to be a hood scoop leads us to believe it will have the same type of hood design as the 2018 HD. Other interesting bits revealed here are around the rear of the pickup. We can see the same interface for the MultiPro six-way tailgate on this truck as the 1500, so at least the Denalis will have the trick tailgate (we'd expect every trim to have it, though). Just like we saw on the Silverado, the Sierra HD gets the stepside feature just ahead of the rear wheels. LED taillights are clearly visible through the thin veiling, and GM's rear steps remain as well. in addition to this 2500 HD, our spy photographers also caught a 3500 HD model. This one isn't a Denali, as the grille shows its hand again. The grille is different than any of GM's designs on the new trucks we've seen thus far, actually. GMC showed us a teaser of what a new Silverado HD grille would look like months ago, but this differs even further than that. It looks rather minimalistic under the sheet for now, with strong horizontal slats. The actual shape and design of the truck is revealed for the most part, since it's just wearing a thin body wrap. Its mirror design appears to be different from last year's, as the arm is completely solid. A sidestep right in front of the rear wheels carries over from the 2500 HD too. We imagine both this truck and the Silverado HD will debut early next year during auto show season. Related video: This content is hosted by a third party.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

Chevy and GMC trucks get CNG option pricing

Chevrolet and GMC have clued us in to pricing of the bi-fuel option for the 2015 Silverado and Sierra 2500HD CNG and 3500HD CNG pickups: it starts at $9,500; we're still missing the rest of the pricing inferred by the word "starts," however. If you remember from the Chicago Auto Show introduction, the 6.0-liter V8 puts out 360 horsepower and 380 pound-feet of torque when drinking gas, 301 hp and 333 lb-ft when inhaling CNG.
Chevrolet figures that a bi-fuel Silverado HD is worth $2,000 in savings if driven 19,500 miles on CNG and 7,500 miles on gasoline in the span of a year, a recoup rate easily attainable to high-mileage fleet owners. It can be specced on double- and crew-cab pickups with single rear wheels, not on dualies.
The 2015 Chevrolet Express and GMC Savana short-wheelbase passenger and cargo vans also get CNG options, starting at $10,825 for the three-tank system, and $12,090 for the four-tank system that can only be had on the cargo hauler. You'll find a bit more info on all of the permutations in the press release below.
