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.

GM Design shows another early Hummer EV sketch

Like a new mother who's still so excited about her one-year-old baby that she can't stop showing ultrasound photos, General Motors is so excited about its biggest new baby, the battery-electric GMC Hummer, that it can't stop showing off development design sketches. The off-road monster with the 200-kWh Ultium battery pack debuted online on October 21 last year. The next day, the GM Design Instagram page posted some of the Hummer's early "theme sketches" leading to the production version. These had a conceptual flair to them, but were rather restrained. A month later, GM uncovered a series of development renderings showing off a much wilder truck bursting with more angles than a geometry text book. The archives have opened up again with a new "ideation sketch," this one between the first believable sketches and the second truck that Master Chief and Doomguy share on their days off.  All three sets of drawings show similar three-box proportions, it's the details that got a ton of love. On this newest sketch, the fenders flare a touch more than on the production truck, but the wheel wells are cut with the kind of clearance found on a Baja 1000 Trophy Truck. Out back, save for the tow hooks, the rear end is totally different than production. The sketch puts illuminated Hummer script across a narrow tailgate flanked by small square, taillights housing six individual elements. Beneath that, a bumper-less rear end puts nothing more than a sloped bash pate between the truck and the rocks it's just scrambled over. To our eyes, this is the best blend of production-ready comfort from the first sketches and zoot suit angles from the second that we've seen so far.  First deliveries of the GMC Hummer EV Edition 1 are expected before the year is out. When we get a chance to absorb the truck in its native habitats, we'll know whether there's cause for disappointment at what could have been. If so, with all this hunger among the monied for something different, we feel like restomodders have been given the perfect head starts on custom rebodied Hummers that would make things right.

GMC Hummer EV recalled over improperly sealed battery pack

Over 700 units of the GMC Hummer EV built during the 2022 and 2023 model years will be recalled due to an improperly sealed battery pack that lets water in. The firm issued a stop-delivery order at the same time as the recall, and it hasn't found how to fix the problem yet. Assigned recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 examples of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are pegged on opposite ends of the automotive spectrum, but they're affected by the same problem: "the high-voltage battery pack enclosure in some of these vehicles may not have been properly sealed," GMC notes, adding that "flanges on the battery pack enclosure may not have been properly primed or electrocoated." Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has found three EVs with this problem: an internal test vehicle that lost power while driving and two customer-owned vehicles that wouldn't start. As of writing, the firm is not aware of any accidents, injuries, or fires related to the issue, and GMC estimates that only about 1% of the recalled EVs are affected. GMC began notifying dealers of the recall in October 2022, and it plans to start reaching out to owners on November 28, 2022. However, a fix hasn't been found yet. In the meantime, the company issued a stop-delivery order and asked dealers not to attempt their own repairs. This isn't the Hummer EV's first run-in with water-related problems. In August 2022, General Motors voluntarily recalled 424 units of the Hummer EV and the Zevo 600 van due to a high-voltage connector that can prematurely corrode. The problem also let water leak into the battery pack, though it sounds like fixing it was reasonably straight-forward and involved applying sealant to the connector.
