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.

2016 Chevy Colorado Duramax gets 31 mpg highway

The 2016 Chevrolet Colorado Duramax and its similarly diesel-powered GMC Canyon sibling are the most fuel-efficient new trucks on the market in America. The Environmental Protection Agency estimates 31 miles per gallon highway, 22 mpg city, and 25 mpg combined for two-wheel-drive Colorado and Canyon diesels. That's just good enough to take the pickup fuel-economy title from the Ram 1500 EcoDiesel HFE, which carries EPA estimates of 29 mpg highway, 21 mpg city, and 24 mpg combined. Four-wheel-drive models offer slightly lower economy figures of 29/20/23, respectively. Drivers can cover quite some distance, too – the GM twins' 21-gallon tanks mean a maximum range of 651 miles. <p>Your browser does not support iframes.</p> Diesel's reputation may be somewhat tarnished in the US after Volkswagen's emissions scandal, but Chevy wants to assure potential customers that there are no tricks with the Colorado's figures. The pickup's engine features NOx-reducing tech like exhaust gas recirculation, and the EPA and California Air Resources Board recently chose the truck to take the additional step of real-world emissions tests. The 2.8-liter Duramax four-cylinder with 181 horsepower and 369 pound-feet of torque had no problems with the more stringent evaluation, and "the agency expressed no issues or concerns," according to the company's statement. The diesel Colorado goes on sale this fall, and the Duramax costs $3,730 over a similarly equipped V6 model. We've gone ahead and included dueling press releases from both Chevy and GMC below for your reading pleasure.

The EPA-estimated highway fuel economy for 2016 Colorado four-wheel drive diesel is 29 mpg. The EPA has issued a Certificate of Conformity for the Chevrolet Colorado Duramax diesel. The agency expressed no issues or concerns following its recent extensive testing and evaluation of the emission control system on the Colorado Duramax diesel.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.
