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.

GMC Sierra EV AT4, Chevy Silverado EV Trail Boss caught in spy photos

We've known for a while now that GMC and Chevy have been working on AT4 and Trail Boss versions of their respective Sierra EV and Silverado EV pickup trucks. But we're getting our best look yet at them with these spy photos. They give us a better idea of what body changes there will be, as well as a close-up of the tires, giving us their size and type. Some basics of off-road trim levels are obvious to spot. Both trucks feature bright red recovery hooks up front. But beyond that, there isn't much different from the outside of either truck compared to the base examples of each. The front bumpers are basically the same profile as the base bumpers, with the exception of the recovery hooks. The Silverado has natural black plastic fender flares, whereas the GMC has body color examples with integrated marker lights. They both get the same standard side steps, and the rear bumpers also appear unchanged. Each of these is equipped with the MultiPro/Multi-Flex tailgate. Chevrolet Silverado EV Trail Boss prototype View 14 Photos Really the biggest change appears to be in the wheels and tires. Each of them have unique designs, but they have the same dimensions. They're 18-inch wheels with 285/75R18 tires. That comes out to just shy of 35 inches in diameter, a good size of tire for an off-roader — and note how it doesn't even look all that large on such big trucks. Said tires are Goodyear Wrangler Territory AT all-terrains. The gas-powered trucks come with slightly narrower (275) mud-terrain versions as standard. Both of these trucks should start somewhere below the range-topping first edition models the two brands are currently marketing to the public, which hover between $95,000 and $110,000 depending on specification. The Silverado WT does start at just under $80,000, and we would expect the Trail Boss and the Sierra EV AT4 to come in somewhere above that, possibly between $85,000 and $90,000. Specifications are a mystery. It seems likely that at least the Silverado will get the WT's dual motors with 510 horsepower and 615 pound-feet of torque. The GMC could potentially get the more powerful motors making 754 horsepower and 785 pound-feet of torque as a way to differentiate itself, though this is speculation. The 204-kWh battery pack is probable, though there are rumors that at least GMC is going to start offering a smaller, more affordable 170-kWh pack that could be an option.
