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 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

2023 GMC Sierra HD 2500 and 3500 will get more expensive

GMC Sierra HD pickups are about to get more expensive again after recently becoming more expensive, according to GM Authority. In July, GMC and Buick raised the prices on certain vehicles in their lineups anywhere from $975 to $1,675 by making the previously optional OnStar a standard feature. Next year, every GMC and Buick model will adopt the upgrade. The big boy Sierra HD gets the biggest increase, being $1,500 for three years of OnStar and the Connected Services Plan plus another $175 for to be "OnStar & GMC Connected Services capable." GMA says the MSRPs for the entire 2023 Sierra HD range will be increased $1,000 on top of that. After doing the math, though, we suspect the increase could in fact be anywhere from about $800 to at least $1,100 after factoring for OnStar. The GMC configurator rings up a price of $43,670 for an entry-level Regular Cab Sierra HD Pro 2WD, GMA says next year's price will be $44,770. GMA didn't break out the next year's destination charge, it's possible GMC is adding $1,000 to the MSRP and $100 to destination. We'll find out when official pricing is announced. GMA's table shows a price of $49,795 for the least expensive SLE trim, whereas the current configurator indicates the truck can be had for $47,295 — a $2,500 difference. The SLE configurator doesn't show any charges for OnStar the way the Pro trim does. So it's possible that after backing out a potential $1,675 for OnStar, the gravy on top is just $825. Not that your wallet will care where how the potato is being sliced when the potato costs an additional $2,500 no matter what. The least dear 2022 Sierra 3500 starts at $43,195 going by the configurator. GMA says that model will command $45,970 next year, a $2,775 difference. As with the 2500 HD SLE, the configurator doesn't show the OnStar charges for the base 3500 Pro trim; subtracting the $1,675 takes us back to the $1,100 difference that appears to be at the heart of all of this. If all goes to plan, the 2023 Sierra HD will give way to a heavily refreshed 2024 model with interior upgrades cribbed from the Sierra 1500. Spy shots reveal a reconfigured instrument panel with a larger infotainment touchscreen of a likely 13.4 inches among the interior tweaks. Related video: This content is hosted by a third party.
