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.

Buick envisioning a refreshed Envision crossover

Buick's first fully Chinese-built vehicle in the U.S., the Envision crossover, is now getting its very first refresh. Cars grow up so fast, don't they? There's no time to be wistful, though, so we need to take a look at this prototype. It looks like the Envision refresh is going to be very mild and focuses on strengthening the family resemblance between it and other Buicks. The waterfall grille now has a horizontal bar that intersects with the badge, as seen on every new and updated Buick since the latest LaCrosse. And although that badge is covered, we wouldn't be surprised if it changes from the all-silver design to the classic red, white and blue version that was reintroduced on the LaCrosse. The lower grilles have been changed, too. The outboard grilles that house the fog lights look smaller and less pronounced than on the current model, and the center piece appears to be thinner and wider. It also more naturally merges into the plastic air dam. The tail of this Envision, though more heavily camouflaged, also shows some minor updates. The most significant of them are the new taillights. They appear to have a similar boomerang shape as those on the LaCrosse, a distinct change from the ovular units of the current model. The lower edge of the bumper seems to have more of a faux diffuser look, and the exhaust tips now blend into the shape of the bumper, rather than ending in simple round shapes. Since this update is clearly a mild one, we would expect to see the new Envision on sale sometime next year, probably as a 2019 model. It will join a rather fresh Buick lineup alongside the new Regal and Enclave.

Buick Avista concept is 'buildable', but not a priority

Buick could build the striking Avista concept that debuted at the Detroit Auto Show, though it's not a top priority, the brand's top executive said Tuesday in New York. "The reaction's been so great, we'll try to run the numbers and see if there's a business case," said Duncan Aldred, Buick vice president of sales, service, and marketing. Buick will show the Avista in red this week at the New York Auto Show as a followup to its Detroit debut. Buick actually built two prototypes, which are being used to promote the brand's performance potential at auto shows around the world this year. "It's very buildable," Aldred told reporters after the reveal of the reveal of the 2017 Encore small crossover before the New York Auto Show. "Ultimately, it comes down to priorities." He added, "We'd love to do it. We could do it, but [there's] lots of things we'd love to do... Nothing to confirm or deny." The Avista concept suggests a sports car with a twin-turbo V6 with 400 horsepower put to the rear wheels. The two-door followed another impressive Buick concept, the Avenir, which was four-door styling exercise from the 2015 Detroit show. Though the Avista remains on the minds of enthusiasts – helped in part by Buick – the priorities for the brand are crossovers. The Avista offers style, but the freshened Encore is the substance for Buick in New York, which along with the Envision, launches this year into the red-hot utility segment. The new Cascada convertible and redesigned LaCrosse also are joining Buick's lineup this year. While the Avista is doable, the brand clearly has other priorities ahead of it. Related Video:
