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.

2024 GMC Sierra HD prices start at $46,295, increasing $100 to $2,500

After an online reveal in October of last year, prices for the 2024 GMC Sierra HD have crept online thanks to GM Authority. The upscale heavy duty pickup gains a new-look design and a more powerful turbodiesel V8 that boosts the tow ratings every HD buyer likes to keep up their sleeves like aces. The optional 6.6-liter turbodiesel Duramax V8 increases horsepower 25 ponies to 470 and torque by 65 twists to 975 pound-feet, both numbers matching the 2024 Chevrolet Silverado HD's diesel output. The torque comes with more useful delivery as well, GMC saying it increased low-end twist by about 25% thanks to a new turbocharger. Buyers who go for the 6.6-liter gas V8 will command 401 hp and 464 lb-ft. Both engines run output through a ten-speed automatic. One the gasser, the new gearbox replaces a six-speed auto. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), the 3500 HD capable of towing up 36,000 pounds. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic and Downpour Metallic. Configuration variables include Regular, Extended and Crew cabs, and Pro, SLE, SLT, AT4, AT4X, Denali and Denali Ultimate trims. The AT4X is late availability, the Denali Ultimate is new for 2024. The Denali Ultimate comes with the 6.6-liter turbodiesel V8, a trim-specific grille, 20-inch machined-aluminum wheels with high-gloss black accents, power-operated running boards, leather upholstery, wood interior trim, massaging front seats, a Kicker sound system and exterior emblems featuring Alaska's 20,310-foot Mount Denali.  Pricing is up by $100 to to $2,500 depending on trim.
