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.

May 2016: FCA wins, Ford and GM stumble on weak car volumes

The May 2016 sales numbers are in, and it looks as though FCA is getting some vindication for boldly cancelling two slow-selling car models. Meanwhile, Ford saw overall sales dip and GM's May volume took a big dive versus the same month in 2015. While Marchionne's decision to axe the Chrysler 200 and Dodge Dart has drawn criticism as being short-sighted, it's working for FCA so far. Although the Dart and 200 aren't out of production yet and no capacity has been shifted to crossover or trucks, May's numbers show that the emphasis on Jeep and Ram models makes sense right now. FCA's US sales rose 1 percent last month compared to May 2015, putting the year-to-date total at 955,186 vehicles, an increase of 6 percent compared to the same period last year. Standouts included the Jeep Renegade, Compass, and Patriot, and the Fiat 500X. Ram pickup sales were down 3 percent. And your fun fact is that Alfa Romeo sales were up precisely 10 percent, for a total of 44 4Cs sold versus 40 in the same month last year. At FoMoCo, the Ford brand took a hit to the tune of 6.4 percent from May 2015 to 2016, registering 226,190 sales last month. Lincoln showed improvement on its modest numbers, going from 9,174 to 9,807, a 6.9 percent increase. Overall, Ford was down 5.9 percent for the month to 235,997; despite the slump, year-to-date total Ford sales are up 4.2 percent to 1,112,939. Strong sellers included Escape, Expedition, F-Series, and Transit - big stuff. Most small and/or efficient models (Fiesta, Focus, Fusion, C-Max) saw sales slides. Fusion sales were also down, likely due to effects of model changeover to the freshened 2017 model. Ford has promised four new crossovers and SUVs by 2020 and if things keep trending this way the company will be able to sell them, but things could change in the next four years. GM saw the worst of it for domestic brands. Retail and fleet sales were down for each of the four divisions, with the May 2016 total dropping 18 percent to 240,450 vehicles. GM's year-to-date sales are down 5.0 percent in 2016 to 1,183,705. Both the Sierra and Silverado were down significantly, and the majority of Chevy, Buick, GMC, and Cadillac nameplates saw sales decreases, with both small cars and larger utilities included. Not even big stuff could help GM this month, it seems. We'll have more on the rest of the industry's May sales as those figures trickle in.

Recharge Wrap-up: Ford HQ gets giant solar array, Chevy City Express gets 24 MPG city

Ford will be building Michigan's largest solar array at its Dearborn headquarters. With funding from DTE Energy, the solar carport will provide covered parking, as well 30 charging stations for electric vehicles. The array is expected to generate 1.13 million kWh per year for Ford's operations, and offset 794 metric tons of carbon emissions. Read more in the press release below. Chevrolet announced the fuel economy for the 2015 City Express, at 25 mpg combined. The cargo van is rated at 24 mpg in the city, and 26 mpg on the highway. Chevy credits the van's inline four-cylinder engine and continuously variable transmission for its impressive city mileage. For its customers - which are mainly businesses - "The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business," says Chevrolet's Ed Peper. The City Express starts at $22,950. Read more in the press release below. Engineers at the University of Wisconsin have developed an efficient engine that runs on a diesel-gas blend. The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio. The Southeast Alternative Fuel Conference and Expo will take place in October in Raleigh, North Carolina. Held at the NC Clean Energy Technology Center from October 22-24, the event will feature a variety of exhibitors, speakers and, most importantly, alternatively powered vehicles. "The three day conference will be a one-stop shop for fleet and transportation related decision makers to learn about return on investment, efficiency and alternative transportation fuels such as biodiesel, electricity, ethanol, propane and natural gas," says Anne Tazewell of the NC Clean Energy Technology Center. If you can't make it to Raleigh for the Expo, you can still enter to win a free two-year lease of a Nissan Leaf at the Center's website. Learn more about the event in the press release, below.
