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 Regal prices slashed

The Buick Regal is getting an aggressive price cut for the 2016 model year to keep pace in a crossover-centric world and its own hyper-competitive midsize sedan segment. The 2016 Buick Regal GS now starts at $35,915, after a $925 destination charge, which amounts to a $3,320 price cut compared to 2015. There's no de-contenting associated with the cost decreases either, and the vehicles are now available with Apple CarPlay. The lower prices follow through much of the lineup. The 1SP Premium model sees a $2,535 savings at $33,415 after destination; the 1SL trim falls $1,000 to $30,840; and the 1SV maintains at $28,915. The decision to make these cuts is meant to better position the midsize sedan against its rivals. "We know consumer sentiment towards sedans has decreased," Buick spokesperson Nick Richards said to Autoblog. CUVs like the company's own Encore are where buyers are moving. "Repositioning the Regal to more aggressively compete in the midsize sedan segment is the first of many steps we are taking in advance of next year's product offensive," Buick sales vice president Duncan Aldred said in a letter to dealers, according to USA Today. The decision probably couldn't have come at a better time because the Regal has suffered so far in 2015. Through July, the company has delivered 10,928 of them, down a significant 19.3 percent from the same period last year. A recent study also found that the model was among the most likely in the US to be sold after just one year of ownership.

2018 Buick LaCrosse gets a mild hybrid model, lower price

Update: Buick provided us with horsepower and fuel economy figures. The text has been updated to reflect this. Buick is rolling out a variety of updates for the 2018 LaCrosse, including a new mild eAssist hybrid. Like the previous generation LaCrosse and Regal eAssist models, this one features a small electric motor and an equally small battery pack that together augment rather than supplant the gasoline engine. The motor, attached to a 2.5-liter four-cylinder engine, helps to make takeoffs smoother and provide additional torque on demand. The gasoline engine still does the majority of the work, though. Combined, the powertrain produces 194 horsepower and 187 pound-feet of torque. It will also allow the LaCrosse to get 25 mpg in the city, and 35 mpg on the highway. While the electric powertrain doesn't provide primary propulsion, it does come with other benefits. The small battery means the LaCrosse maintains a folding rear seat. The battery also provides power to accessories when the engine shuts off at a standstill. This mild hybrid powertrain will be the standard engine for all 2018 LaCrosses, and they come with a lower base price. The 2018 model will start at $31,415, which is about $1,500 less than the lowest priced 2017 V6 LaCrosse. The V6 will still be available as an option, and Buick has updated it, too. The 2018 V6 models will also all come with a new 9-speed automatic transmission. The new LaCrosses will go on sale this fall. Related Video: Image Credit: Buick Green Buick Hybrid Luxury Sedan
