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.

Vert-A-Pac train cars kept your Chevy Vega's price in check

Our apologies to those who've seen this before, but for the rest of the class, how awesome are these pictures of the Vert-A-Pac shipping system General Motors came up with to ship the Chevrolet Vega back in the 1970s? Developed along with Southern Pacific Railroad, GM was able to double the amount of Vega models it could ship by packing them into the unique storage cars vertically.
At the time, rail cars could fit 15 vehicles each, but Chevrolet was able to lower shipping costs by making it possible to ship 30 Vegas per rail car, in turn allowing the price of the Vega to remain as low as possible. Each rail car had 30 doors that would fold down so that a Vega could be strapped on, and then a forklift would come along and lift the door into place. All the cars were positioned nose down, and since they were shipped with all of their required fluids, certain aspects had to be designed specifically for this type of shipping, including an oil baffle in the engine, a special battery and even a repositioned windshield washer reservoir. See for yourself in our image gallery above.

2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.
