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.

2016 Buick Envision might be your first Chinese-built crossover

At the Detroit Auto Show, the new Envision crossover flips the traditional Buick paridigm on its head. We've been hearing for years about strong sales of the Buick brand in China, but now we'll see if North America is ready for a Chinese-built (but, as GM is very quick to point out, American-engineered) CUV. The Envision rides on the latest version of the Delta 2 platform that underpins many GM vehicles. It'll slot between the tiny Encore and the cavernous Enclave, which is a nice sweet spot for volume sales in the hot crossover market. Gas is cheap, and Americans are eating these vehicles up – in a market like this, does it really matter where the Envision was actually screwed together? The powertrain package is surprisingly compelling – perhaps there will be some life to the driving experience. Motivation is provided by a 252-horsepower turbo inline-four and a six-speed auto, and in a first for a Buick crossover, it'll feature the torque-steer fighting HiPer suspension, which splits up steering and suspension duties in a way that'll tidy up the front axle's manners under power. A few other neat tricks make it into the Envision, like active grille shutters to squeeze some extra efficiency out of the CUV, and available park assist. The 2016 Buick Envision goes on sale later this year. Buick Introduces Envision Luxury Crossover DETROIT – The 2016 Envision is an all-new luxury compact crossover with segment-challenging driving dynamics, advanced technology, connectivity and Buick's trademark interior acoustics. It is a global vehicle, designed from the ground up as a Buick luxury compact crossover. It goes on sale in the U.S. in the second quarter of 2016. "The all-new Buick Envision is a modern, confident and responsive luxury compact crossover that combines the brand's core characteristics with great performance features like our HiPer strut suspension," said Duncan Aldred, vice president of Buick.

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.
