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.

EcoCar3 will convert Camaro to bitchin' eco rides

In the 47-year-history of the Chevrolet Camaro, there have been countless college-age kids spending a ton of time getting under the hood and souping 'em up. Now, General Motors is adding a twist to the concept by donating 16 Camaros for the EcoCar challenge that puts university teams together to wring out better fuel-efficiency out of various vehicles. No word on whether there will be donuts on anyone's lawn, as suggested by 80's punks the Dead Milkmen, but the idea's never a bad one. EcoCar3 will feature 16 teams such as Arizona State, Penn State, Ontario's University of Waterloo and, of course, Detroit's Wayne State University. They'll spend the next four years "[reducing] environmental impact, while maintaining the muscle and performance expected from this iconic American car," as the EcoCar organizers say. The goal is to maintain body design and safety standards while boosting efficiency and lowering emissions, but the actual process is far more complicated than that description suggests. The California Air Resources Board (CARB) and Bosch are among the sponsors of the contest, which is also put on by the US Department of Energy and managed by Argonne National Laboratory. Penn State won Year Two of the three-year EcoCar 2 competition with its E85 plug-in hybrid electric vehicle converted out of a Chevy Malibu. The grand-prize winner of EcoCar2 will be announced in June. Check out the EcoCar3 website and see the announcement video below for more details. This content is hosted by a third party.

Stolen '79 Vette finds home at Dream Cruise [w/video]

After over three decades of waiting, George Talley finally has his 1979 Chevrolet Corvette back, and it's as good as new. The coupe was stolen off of a Detroit street in 1981, but last year Talley received a call that the 'Vette was found in Mississippi. General Motors Executive Vice President Mark Reuss heard the touching story and had the automaker help get the car back to the Motor City. Now after a restoration by the GM Heritage Center and Autometric Body Shop, Talley got the keys to his Corvette back during the Woodward Dream Cruise. When Autoblog spoke to him after the coupe was returned last year, Talley said that the first thing he wanted to do with it was, "I think I'm going to cruise Belle Isle." We hope he enjoys the drive because the experience is a long time coming. You can watch Talley's excited reaction to see his newly refurbished 'Vette for the first time in the video below. Stolen Corvette Reunion and Restoration on Display at Woodward Dream Cruise 2015-08-14 DETROIT – George Talley's 1979 Corvette was stolen 33 years ago and recovered last year in Mississippi.

The GM Heritage Center, in conjunction with Autometric Body Shop in Center Line, Mich., took on the restoration project. Talley got an opportunity to see the progress ahead of its official reveal at the Woodward Dream Cruise on Saturday.
