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.

Chevy reveals new IndyCar aero package

The IndyCar Series is not one that demands its participating teams and automakers to design their own chassis as they do in Formula One, but for this season, the organizers have opened it up to allow for custom aero packages. What you're looking at here is the new look of the chassis to be fielded by teams running under Chevy power. Based on the Dallara DW12 chassis – introduced three years ago and named after the late Dan Wheldon – Chevy's new package is designed for road courses and short ovals, with the speedway configuration to be revealed later. The kit features new wings front and rear and more sculpted side pods. It's also got new wedges at the back to envelop the otherwise open wheels that are a hallmark of Indy racing, a more streamlined engine cover and bigger rear bumper pods. The new package will debut at the Grand Prix of St. Petersburg that will kick off this year's championship in Florida on March 29, followed by the road-course grands prix in Louisiana, Long Beach, Alabama and Indianapolis before the new package needs to be ready for the Indy 500 late in May. Half of the teams on the starting grid this season will be running under Chevy power and are expected to use this new aero kit, with the remaining Honda teams slated to run a different package of their own. Chevrolet Debuts All-New 2015 IndyCar Aero Package Chevy-developed bodywork delivers improved aerodynamics 2015-02-17 INDIANAPOLIS – Chevrolet-powered racecars in the 2015 Verizon IndyCar Series will feature Chevrolet-developed aero packages. Chevrolet introduced the road course/short oval body design today at the Indianapolis Motor Speedway. It is distinguished from the previous racecar with new front wing elements, sculpted side pods and a new rear wing. A speedway configuration for the aero kit, designed for high-speed ovals, will be introduced ahead of its competitive debut at Indianapolis in May. "This is an important milestone in Chevrolet's involvement in IndyCar racing," said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports. "We focused on developing an aerodynamic package that delivers an balanced combination of downforce and drag, along with integrated engine performance. It's a total performance package." The new Chevy road course aero configuration delivers greater aerodynamic performance than the previous design.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
