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 Chevrolet Silverado EV output jumps to 754 hp and 785 lb-ft

A couple of days ago, GMC unleashed its 2024 Sierra EV Denali Edition 1 pickup, the luxury truck division's version of the 2024 Chevrolet Silverado EV. As has been the case between Chevy and GMC for decades, GMC designers worked to put ample visual difference between the two pickups that share the similar underpinnings. Unlike what's been the historical case, GMC announced output figures for the Sierra EV well above those for the Silverado. Preliminary estimates for the battery-electric Sierra with the dual-motor powertrain are 754 horsepower and 785 pound-feet of torque. Chevy revealed the 2024 Silverado EV in January with 664 hp and 785 lb-ft in RST trim. We're not sure what happened after the GMC debut, but the Bowtie has updated the Silverado's output to match the GMC with 754 hp and 785 lb-ft. Chevy truck communications spokesperson Sean Szymkowski submitted a statement to various outlets explaining, "As we prepare for production of the Silverado EV, our engineering team has further refined the estimated performance specs for the 2024 Chevrolet Silverado EV RST First Edition. GM now estimates horsepower to be up to 754 and torque up to an estimated 785 lb-ft when Wide Open Watts mode is engaged." It's possible Chevrolet did so in order to forestall backlash about the disparity, or it's possible the automaker already planned to do so after the GMC dropped. On the ICE side, buyers have got used to powertrain parity, the Silverado and Sierra offering the same engines with the same outputs even with pricing about $3,600 apart on the respective top trims. No matter how the decision was made, the benefits redound to Silverado EV buyers. By the way, the "Wide Open Watts" reference refers to the driving mode required to extract these peak power figures. In the GMC Sierra EV, this is called Max Power Mode. We're still looking for clarity on the output figures in everyday driving modes, we believe those will be the same 510 hp and 615 lb-ft that's the maximum in the lower trim Silverado EV Work Truck.    With a year to wait before the Silverado RST EV reaches reservation holders, and with the Chevrolet Work Truck providing real-world feedback before the RST arrives, don't be surprised at more tweaks made to both the Silverado and Sierra EVs before they hit the market.

Full-size trucks are the best and worst vehicles in America

You don’t need me to tell you that Americans love pickup trucks. And the bigger the truck, the more likely it seems to be seen as an object of desire. Monthly and yearly sales charts are something of a broken record; track one is the Ford F-Series, followed by the Chevy Silverado, RamÂ’s line of haulers, and somewhere not far down the line, the GMC Sierra. The big Japanese players fall in place a bit further below — not that thereÂ’s anything wrong with a hundred thousand Toyota Tundra sales — and one-size-smaller trucks like the Toyota Tacoma, Ford Ranger and Chevy Colorado have proven awfully popular, too. Along with their sales numbers, the average cost of new trucks has similarly been on the rise. Now, I donÂ’t pretend to have the right to tell people what they should or shouldnÂ’t buy with their own money. But I just canÂ’t wrap my head around why a growing number of Americans are choosing to spend huge sums of money on super luxurious pickup trucks. Let me first say I do understand the appeal. People like nice things, after all. I know I do. I myself am willing to spend way more than the average American on all sorts of discretionary things, from wine and liquor to cameras and lenses. IÂ’ve even spent my own money on vehicles that I donÂ’t need but want anyway. A certain vintage VW camper van certainly qualifies. I also currently own a big, inefficient SUV with a 454-cubic-inch big block V8. So if your answer to the question IÂ’m posing here is that youÂ’re willing to pay the better part of a hundred grand on a chromed-out and leather-lined pickup simply because you want to, then by all means — not that you need my permission — go buy one. The part I donÂ’t understand is this: Why wouldn't you, as a rational person, rather split your garage in half? On one side would sit a nice car that is quiet, rides and handles equally well and gets above average fuel mileage. Maybe it has a few hundred gasoline-fueled horsepower, or heck, maybe itÂ’s electric. On the other side (or even outside) is parked a decent pickup truck. One that can tow 10,000 pounds, haul something near a ton in the bed, and has all the goodies most Americans want in their cars, like cruise control, power windows and locks, keyless entry, and a decent infotainment screen.
