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.

Is Buick's surprise Detroit concept a Camaro-sized coupe?

Tomorrow night marks the unofficial start of the 2016 Detroit Auto Show. Keep your eyes peeled for a number of reveals, including a surprise debut from Buick. Yes, Buick. And we think it's going to be something really hot. According to a report from Bloomberg, the Tri-Shield's secret car could be a Camaro-sized sport coupe concept. As Bloomberg explains, it'd certainly gel with the impression the company is trying to put out – that it's no longer a brand for those with one foot in the grave. Introducing a sports coupe, even as a concept, could certainly reinforce that message. And if it happens to make production – which is not a certainty, Bloomberg's secret source says – it could certainly help Buick drive its average buyer age down from 59. Bloomberg doesn't offer any speculation on Buick's new coupe, but we have no problem making educated guesses. Our most reliable conjecture is this: it will ride on General Motors' Alpha platform, which underpins both the Camaro and the Cadillac ATS. And with a certain twin-turbocharged V6 in the GM stable, we've got an idea of what kind of engine could be shown. That speculation will have to suffice for now. But don't worry, we'll have official details, live images, and video tomorrow when Buick unveils its new concept in Detroit's Eastern Market.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.
