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.

GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

2018 GMC Canyon Denali isn't worth the money

In the GMC lineup, Denali is the top dog. It's the trim with all the bells and whistles, and often provides an experience comparable to Cadillac. Unfortunately that's not the case in the GMC Canyon Denali we drove recently. In the Canyon's case, the Denali trim isn't worth the price premium because it isn't luxurious enough and doesn't distinguish itself from the midlevel SLT trim. While the outside maintains the Denali look with a unique chrome grille, chrome door handles, 20-inch wheels, and big Denali badges (which a guy at a car wash immediately noticed when this editor drove past), the interior and feature set don't rise to meet the borderline Cadillac image of Denali. All GMC did to spruce up the already drab, gray, plasticky interior of the Canyon was give it black leather, some real aluminum trim, some fake wood trim, and stitched soft-touch surfaces. The aluminum and leather are nice touches, but they don't look much different from the black and aluminum-look plastic in lower trim models. The fake wood also looks really fake. They're also exactly the same upgrades as what you'll find in an SLT. But the SLT offers a dark brown color scheme as an option, which would help alleviate the dinginess, and the SLT, equipped exactly like a base Denali, costs $2,690 less at $41,575. The same issue comes up with equipment. The Denali has heated seats and steering wheel, navigation, automatic climate and navigation, but so does the SLT. The big problem here is that Denali is supposed to indicate the best, most luxurious vehicle GMC has to offer, but there's not enough differentiation — or specialness, even — to separate it from a well-optioned SLT. GMC needs to give the Denali something more. It needs some real wood trim, or perhaps some interior schemes with contrasting materials you can't find in other Canyons. It should have some other special luxury features included that can't be added to lower trim GMCs such as a heads-up display, automatic windshield wipers, push-button keyless entry and starting, things like that. The real reason to buy the Canyon Denali is really to get the prestige that the Denali badge brings, rather than the specific equipment it has — the Denali name has some value, after all. But if you can look past the badge and focus on practicality, the SLT is the runaway winner, offering the exact same experience for a notably lower price.
