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.

2017 Buick LaCrosse an evolution of sharp Avenir concept

After years as a bloated, uninspiring, but comfortable near-premium sedan, Buick has taken the wraps off a leaner, lither, far more stylish LaCrosse. The third-generation model has just made its debut at the 2015 Los Angeles Motor Show. While there's a lot to talk about, let's first address the new, Avenir-inspired sheetmetal. The fascia is basically the concept car smoothed over into production form, featuring the same winged trishield. In place of the chrome-trimmed waterfall, the LaCrosse gets a blacked-out, recessed grille with a chrome surround. It looks good in photos but it's better in person, adding a real sense of complexity and depth to the front end. The headlights and lower fascia, meanwhile, adhere closely to the concept. The same cannot be said of the LaCrosse's tail. While the taillight lighting pattern is similar, the overall shape of the lighting element is radically different, refining the design featured on the back of the Regal. Also gone, sadly, is the Avenir's boattail rear deck. Instead, the LaCrosse gets a small rear deck that curves up into a pleasant duckbill spoiler. The rest of the tail is pleasantly restrained. Perhaps the weakest point is the profile, where Buick has instituted a "split-spear" design, featuring a strong shoulder line above the rear wheel well, which sits below an even stronger character line that curves down and towards the front of the car. It strikes us as just a little too much, like the Impala. Underneath that sheetmetal, Buick has managed to trim nearly 300 pounds of body fat, nearly half of which came from the vehicle's actual structure. That 300 lbs, according to Buick's engineers, is equivalent to a Kenmore side-by-side refrigerator, in case you needed a helpful comparison. Despite the weight savings, Buick has upped the torsional rigidity for this new model by 15 percent. The LaCrosse's cabin features a strong, cockpit-like design, with a high, floating-bridge center console. This is possible due to Buick's adaption of the Electronic Precision Shift system, introduced earlier this month on the new Cadillac XT5. Despite the new-fangled console design, Buick's retained the wraparound cabin style introduced on the second-gen model. Based on a quick crawl around the interior, space is great in front, although ingress in back is somewhat difficult due to the roofline. You're probably wondering why we haven't said anything about the mechanicals just yet.

NC dealer falsely announces return of Regal Grand National, Regal GNX

Like many new car dealers, Liberty Buick GMC gets so excited about its brands' new wares that it puts out press releases announcing when new models are on the way. That's not typically national news, but the Charlotte, NC store has created a bit of internet hubbub by announcing that it will be "one of the first dealers in the country to offer the Buick Regal GNX," and it's even started to add customers names to a waitlist. Only one problem: Despite seemingly annual rumors and calls for such a model, Buick hasn't announced any Grand National models at all – let alone a GNX – and no such models are actually in the cards. The Liberty Buick press release talks in a nostalgic, venerative tone of the original 1982-1987 GN franchise, and goes on to say: "These returning relics will be based on the highly-acclaimed Alpha vehicle architecture currently used in the Cadillac ATS, 2014 Cadillac CTS, and soon to be in the sixth-generation Chevy Camaro. Alpha is the internal name of a General Motors vehicle architecture engineered to underpin compact and mid-size rear-wheel-drive vehicles." In the release, Liberty Buick claimed the GN/GNX models would arrive in late 2015, citing a coupe bodystyle, including a rather fantastical-looking GNX rendering from Bestride.com. Unsurprisingly, none of this is true. Autoblog reached out to Buick for comment about the release, and brand communications manager Nick Richards confirmed that the company had discussed the matter with Liberty Buick representatives. Richards went on to say that the release was wholly incorrect, proclaiming "an agency [for the dealer] picked up a lot of stuff off the internet" and ran with it, including an old Car and Driver story from 2013. The dealership subsequently issued a retraction, with Scott McCorkle, owner of Liberty Buick GMC saying: "We love the idea of the Buick Regal GNX coming back to our showroom but for now, it's only a concept. Bottom-line, the article was incorrect.
