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.

Chevy Corvette Stingray picks up another award, this time from Automobile

The new Chevrolet Corvette Stingray has picked up another buff book accolade after capturing Road and Track's Performance Car of the Year award. The seventh-generation of America's sports car (sorry Viper, Mustang, et al.) has been named Automobile Magazine's Automobile of the Year.
Automobile's award to the Corvette over competitors is the mirror image of its rival Motor Trend, which named the Cadillac CTS its car of the year over the C7. The CTS was, according to the Automobile team, the closest contender to the mighty Stingray. Great news all around for General Motors it seems.
As for what pushed the Corvette past its distant, four-door cousin, Automobile commended its excellent, 6.2-liter V8 calling the car's performance "simply awesome" while also remarking that it is easier to drive fast than ever before thanks to steering and chassis tweaks. Following a theme set by other publications, there were also plaudits for the interior, of all things, with the buff book complimenting the car's ergonomics and material quality, while also praising the standard seats.

GM cutting Chevy Sonic, Buick Verano production by more than 20%

General Motors' Orion Assembly plant in Michigan is seeing even more production cuts this year to further reduce inventories of the Chevrolet Sonic and Buick Verano. These latest adjustments mean layoffs for about 100 workers in phases starting in July. "GM Orion Assembly will adjust plant production capacity to better align with market demand," the company said in a statement announcing the change. Through May, sales of the Sonic are down 28.5 percent to 29,082 vehicles, and the Verano is off 15.6 percent, with 15,279 sold this year. According to unnamed plant insiders speaking to Automotive News, the assembly rate is slowing at Orion Assembly from the current 33 cars an hour down to 26 an hour, a 21-percent reduction. GM is also reportedly going to keep the plant idle for three weeks during the normal summer shutdown, rather than the usual two. Earlier in the year, the factory was idled for two weeks due to excess supply of the Sonic and Verano. In March, it was closed again for several days for the same reason. The Orion Assembly plant is the future home to the line for the Chevy Bolt EV. GM Statement: GM Orion Assembly will adjust plant production capacity to better align with market demand. A phased layoff of approximately 100 employees will begin in July 2015 and conclude by year-end.
