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.

Mustang retakes monthly pony car sales crown from Camaro

Going back to their origins in the Swinging '60s, the Ford Mustang and Chevrolet Camaro have been fierce rivals for fans' hearts and dollars. Historically, the Ford often led in volume, but Chevy took the muscle car top spot in 2009 upon the Camaro's rebirth. However, with the launch of the latest Blue Oval pony car, the tide is turning back in Ford's favor. November was the first full month of sales for the new 2015 Mustang, and according to TheDetroitBureau.com, the model did spectacularly well. The Blue Oval shifted 8,728 of them, up 62 percent from same month last year, with the automaker proclaiming it the model's best November sales since 2006. Conversely, 4,385 units of the Camaro were delivered, down 13.5 percent year-over-year, meaning its sales were roughly half that of the new-generation Mustang. Ford is understandably happy with the results, and product development director Raj Nair even hinted to TDB that another version of the Mustang might be unveiled at January's North American International Auto Show. Rumor has it that the model will be the even more potent Shelby Mustang GT350R. Despite the Mustang's November success, the Camaro outsells it year to day. So far in 2014, Ford has sold 73,124 Mustangs versus 79,669 examples of the Camaro. With December offering the last chance for an overtake, the Bowtie may yet remain king for this year's sales crown. A new Camaro is peeking over the horizon, as well. It's reportedly moving to the Alpha platform used by the Cadillac ATS, and production could start in late 2015. Prototypes are already testing at the Nurburgring, and camouflaged examples have been spotted weirdly being compared to its '80s forefather.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
