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 extends vehicle production cuts into mid-March due to global chip shortage

DETROIT — General Motors said on Tuesday it was extending production cuts at three North American plants until at least mid-March due to the global semiconductor chip shortage, while vehicles at two other factories would only be partially built. GM, whose shares dipped 1% after the announcement, did not disclose the impact volumes or say which supplier and vehicle parts were affected by the chip shortage. But it said it would focus on keeping production running at plants building its highest-profit vehicles, full-size pickup trucks and SUVs. GM said it intended to make up as much lost production as possible once the shortage chip eased. "Semiconductor supply remains an issue that is facing the entire industry. GM's plan is to leverage every available semiconductor to build and ship our most popular and in-demand products," GM spokesman David Barnas said. GM said it was extending downtime at its U.S. plant in Fairfax, Kansas, its Canadian factory in Ingersoll, Ontario, and its Mexican facility in San Luis Petosi until mid-March when it would reassess the situation, he said. In addition, GM would build but leave incomplete for final assembly vehicles at Wentzville, Missouri, and its Mexican plant at Ramos Arizpe. GM vehicles affected by the idled plants include the Chevrolet Malibu sedan, Cadillac XT4 SUV, Chevy Equinox, and GMC Terrain SUVs. Vehicles to be left incomplete for now included the Chevy Colorado, GMC Canyon pickups and Chevy Blazer SUV. This week, GM had said it was idling the three factories where it has now extended downtime and said it would halve production at a plant in South Korea. The chip shortage has affected many automakers, including Toyota, Volkswagen, Stellantis, Ford, Renault, Subaru, Nissan, Honda and Mazda. Asian chipmakers are rushing to boost production but say the supply gap will take many months to plug. German chipmaker Infineon said the shortage would get worse in the near term. The chip shortage is expected to cut global output in the first quarter by more than 670,000 vehicles and last into the third quarter, IHS Markit said. AutoForecast Solutions estimated total lost production this year could reach 1 million vehicles. Honda and Nissan said on Tuesday they would sell 250,000 fewer cars in total this financial year due.

2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:
