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.

Watch this phantom Buick drive itself down the highway in a snow storm

Years ago, General Motors used Buick cars to test out the idea of a "smart highway" concept. More recently, GM has been talking up its award-winning Super Cruise semi-autonomous technology that will roll out with Cadillac and make its way to Buick. The LeSabre in the video above has nothing to do with any of that.
On Interstate 15 in Utah, a man driving this LeSabre got into an accident that rearranged the front end and set the horn on permanent blare. At the time of writing this, no one is sure what happened next, but the man ended up sitting in the snow in the highway median while his car carried on down the highway without him. Passing traffic stayed well to the right.
The 51-second video below provides a different take on our autonomous future. A local newscast on KUTV covered the story the evening of the incident, but the Utah Highway Patrol didn't have any update on the fate of the LeSabre. We'll take that to mean that Buick's take on Christine could still be out on the prowl... so watch out!

Opel Cascada is Europe's Buick convertible [w/video]

As we reported earlier, there has been much speculation regarding a Buick convertible of sorts. The most ringing endorsement of this conjecture comes today from General Motors Europe, as the new Opel Cascada has debuted on the interwebs. Opel calls the four-passenger Cascada an "athletic, glamorous midsize convertible." With a length of 4,697mm (185 in.), the Cascada is as long as an Audi A5, to which GM has said it would be slightly larger.
The Cascada, which is Spanish for waterfall, features a cloth convertible top that retracts in 17 seconds and at speeds up to 50 km/h (31 mph). The Cascada features a 1.4-liter turbo gas engine, 2.0-liter turbodiesel with 165 horsepower and a range-topping 1.6-liter turbocharged Ecotec engine that puts out 170 horsepower and 280 Nm (207 lb-ft). Power is sent through either a six-speed manual or six-speed automatic transmission.
According to GM, the Cascada will also come rife with luxury and tech features. In addition to adaptive forward lighting and ergonomic heated front seats, the convertible will feature Opel Eye, which is a front camera that can recognize traffic signs and incorporates lane departure warning and forward collision alert.
