The electric Hummer gets a new logo

GM submitted three trademark applications to government offices here and in Canada, as discovered by GM Authority. Two applications went to the U.S. Patent and Trademark Office and the Canadian Intellectual Property Office on February 4 this year, seeking to reserve the new Hummer logo, at the top in the image above. Note, the two logos aren't to scale; they're about the same size all things being equal, but we shrunk the old mark. GM sent a second application to the USPTO on February 7 requesting the brand name "Hummer" for application to "motor land vehicles, namely, automobiles, trucks and sport utility vehicles; bicycles." True, we've seen the new Hummer script stretched across the front of the coming electric pickup in a teaser clip, but the paperwork continues the process of getting the entire continent ready for the alternate universe resurrection of one of America's most notorious brands.     In 2010, gas prices were in orbit, GM committed to closing the Hummer brand, vandals were setting fire to the scattered Hummers left on dealer lots, the Chevrolet Corvette ZR1 made 638 horsepower, the eco-minded revered the Toyota Prius and the Tesla Model S was still two years away. In that year, it would have been hard to say something more bonkers than, "Hummer's coming back in ten years as an electric pickup, its top trim making 1,000 horsepower and 11,500 pound-feet of torque." But here we are. The new logo's squareness connects it to the resolute bluntness of the old mark, yet the thinner font and chopped corners both modernize the old logo and lessen its truculence. The brand appears headed the same way, with lurid specs and square-jawed looks just like old times, but having in LeBron James a more modern take on the hardcore male vibe than it once got from (unpaid) association with guys like Arnold Schwarzenegger. To be fair, old Hummer commercials always featured women in the driver's seat, or men and young boys dreaming of big adventures, or Regis Philbin chatting up models, but the marketing department couldn't — or didn't want to — outrun the lineup's reputation on the street. We'll see how the electric version and its “incredible on- and off-road capability" fare. According to the teaser site, the new Hummer's debut is still on track for May 20. If the brand manages to recreate the old H3T pickup but with an electric powertrain, it's got one buyer right here lined up already. Related Video:

5 things we love about the 2019 GMC Sierra AT4

NEW YORK — The 2019 GMC Sierra AT4 proves that GM's upmarket truck and SUV brand is getting serious about offering rough-and-tumble capability to rival the Ford F-150, Toyota Tundra, Ram 1500 and Nissan Titan. Until the Sierra AT4 rolled onstage at a media event in lower Manhattan, prior to this year's New York Auto Show, the GMC brand had been more focused on luxury touches like fancy chrome wheels and posh interiors — no surprise, considering the upscale SLT and Denali trim levels account for the vast majority of GMC sales. So now GMC wants to get muddy and adventurous? Well, yes and no. The AT4 adds hardware that'll take truck buyers off the beaten path, though this GMC isn't anywhere close to being a Spartan, no-frills work truck. To better explain, let's look at five key features we love about the 2019 GMC Sierra AT4: More than stickers and chrome The Sierra AT4 isn't a cynical marketing ploy, there is some true all-terrain toughness built into this pickup truck. A factory-installed lift kit raises the AT4 by two inches, while Rancho monotube shocks, a locking rear differential, a two-speed transfer case and standard all-wheel drive prove this GMC can dare to venture off paved surfaces — though you might risk getting mud and muck on the truck's handsome 18- or 20-inch alloy wheels. Power and economy The Sierra AT4 comes standard with a 5.3-liter V8 coupled to an eight-speed automatic transmission. In the standard Sierra 1500, this engine produces 355 horsepower. GMC didn't mention engine specs here in New York, though it's possible the AT4 might get a small power bump. This engine should be plenty for most truck buyers, though GMC offers two tempting alternatives. These include a turbo-diesel 3.0-liter inline-six, along with a 6.2-liter V8. Both motors are paired to stop-start fuel-saving systems, along with a new 10-speed automatic transmission. Carbon fiber cool factor The GMC Sierra's available carbon-fiber cargo bed, called CarbonPro in GMC-speak, trims 62 pounds of weight, as compared to a traditional all-steel bed. This slick feature uses carbon composites for interior panels and, judging from GMC's videos of burly bricks and huge hammers being thrown into a CarbonPro cargo bed, it should prove more than up to the task of ... well, having someone throw bricks and hammers into the cargo area.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.
