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.

Buick lowering base prices on Regal, Verano

Buick might have two new options for buyers in the market for an inexpensive luxury sedan. In a move similar to the introduction of the LaCrosse 1SV base trim a few months ago, the brand is ready to offer cheaper, entry-level versions of the Regal and Verano. Like the LaCrosse 1SV, the Verano 1SV mostly cuts dealer margins to reduce the cost for customers. The small sedan is priced at $21,065, plus $925 destination, which is a significant $2,315 drop compared to the next higher trim. The powertrain is still a 2.4-liter four-cylinder making 180 horsepower and 171 pound-feet of torque and a six-speed automatic, but buyers lose out on satellite radio. According to CarsDirect, dealers are making just $106 on this model, versus $935 on the higher grade. Meanwhile, the Regal 1SV charts a slightly different path to a lower price. The trim starts at $27,065, which is a $2,925 savings over the next trim. Buyers still get leather seats too, but the powertrain here is a 2.4-liter four-cylinder without eAssist that makes 182 hp and 172 lb-ft of torque and a six-speed automatic. That's a 77 hp deficit compared to the turbocharged Regal, and combined city/highway fuel economy dips to 23 miles per gallon combined, compared to 24 mpg with forced induction. Buick is introducing the 1SV models in hopes of grabbing more attention for the brand. "We added this new base level to some models as a means of expanding the opportunity for more customers to experience Buick vehicles. The addition of these trims will create an increased awareness and consideration of these vehicles when being compared to the competition," said company spokesperson Nick Richards to Autoblog. However, you might not see many of these inexpensive Buicks on the road. "On the Verano, we suspect dealers will opt to stay away from a car with around $100 between invoice and MSRP - that's the pattern we've been seeing on the LaCrosse 1SV, which is practically impossible to find," said CarsDirect Senior Pricing Analyst Alex Bernstein to Autoblog. Also, the Regal 1SV's switch to a less powerful, naturally aspirated engine "could be a turn-off for some shoppers," he said. Related Video:

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
