GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.

GMC Canyon next generation previewed with off-road AT4X trim

GMC is preparing to give the Canyon, its smallest and most affordable pickup, a complete makeover. While we won't see the truck for a few months, the company released a preview image to give us an idea of what to expect and confirmed the lineup will include an AT4X model. Although the teaser keeps most of the sheetmetal hidden, the truck appears to receive a more chiseled hood and concave door skins that should make it look less slab-sided. The fenders are eye-catching as well: They're more punched-out that the current-generation model's. Keep in mind that we're looking at the AT4X trim, which will be positioned as the off-road champion of the range and should consequently get a brawnier-looking design. Other off-road goodies include big Goodyear Wrangler tires wrapped around 17-inch beadlock-capable wheels, plastic wheel arch flares, and rock rails. GMC is keeping additional details under wraps, but we're guessing suspension tweaks are part of the package as well. After all, the current-generation AT4 benefits from a one-inch suspension lift and skid plates, among other upgrades. This isn't the first time we've seen or heard of the Canyon AT4X. Our spy photographers caught a camouflaged prototype that looks taller and considerably more rugged than the AT4 in July 2021, and the Canyon AT4 OVRLANDX concept introduced in August 2021 seemingly previewed some of the features that will trickle down to the production model, including the rock rails and wheel arches. GMC will unveil the next-generation Canyon this summer, and we expect to hear more about it in the coming weeks. And, if a new Canyon is around the corner, that likely means that the next Chevrolet Colorado isn't far behind. Both will compete directly against the new Ford Ranger, which has only been unveiled for overseas markets as of writing and which will spawn a range-topping, V6-powered Raptor. Another competitor the duo will need to fend off is the Nissan Frontier, which got its first update since the 2005 model year for 2022. Already offered on the 2022 Sierra, the outdoorsy AT4X trim will spread across the GMC range in the coming years. Nothing is official yet, but earlier spy shots strongly suggest that the Sierra Heavy Duty will be treated to the AT4X treatment in the not-too-distant future.
