Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan. Scroll down for the official press releases from Chevrolet and GMC.

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.

GM Issues Four New Recalls For 90,000 Vehicles

One day after releasing an internal report that found a pattern of "incompetence and neglect" within the company, General Motors announced four more recalls that affect 89,126 vehicles. One of the recalls affects 31,520 vehicles that may contain a defect that could prevent airbags from deploying in a car accident. GM said it was aware of at least one crash in which a vehicle occupant sustained an injury because the airbags didn't deploy when they should have. The company said it was aware of other crashes that were similar in nature, but it is not yet known whether they're related to the condition, in which the shorting bar inside the driver's airbag may occasionally contact the airbag terminals. If the car and terminals are touching each other in a crash, the bags will not deploy. Vehicles from the 2012 model year are affected by the problem, and they include the Buick Verano, Chevrolet Camaro, Cruze and Sonic. GM has conducted two previous recalls for this condition involving 7,116 cars. GM is also recalling 57,512 models of the 2014 Chevrolet Silverado 1500, 2014 GMC Sierra 1500 and 2015 Silverado HD, Tahoe and Surburan, as well as the 2015 GMC Sierra HD, Yukon and Yukon XL models because their radio control modules may not work, and thus prevent certain audible safety warnings. Certain models of the 2013-2014 Chevrolet Spark and 2013 Buick Encore are being recalled for a different airbag problem, which could prevent airbags from deploying properly during a crash. And 33 2014 Chevrolet Corvettes are being recalled for yet another airbag problem, in which an internal short circuit could disable the airbags. So far in 2014, General Motors has issued 34 separate recalls that affect approximately 15.9 million vehicles – more than the company has sold in the past five years combined. GM Announces Four Recalls DETROIT – General Motors today announced three safety recalls and one non-compliance recall, all of which were reported to the NHTSA on Thursday, June 5, 2014. In all cases, customers will receive letters from GM letting them know when they can bring their vehicles into a dealership, where all repairs will be performed free of charge and courtesy transportation would be provided as needed.
