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.

2020 Chevy Silverado HD vs. 2019 Ram, Ford heavy duty trucks: How they compare on paper

Last year was all about the latest in light-duty full-size pickup trucks, so this year, Ram, Ford and Chevy are launching the heavy-duty variants. The first out of the gate is the redesigned 2019 Ram 2500 and 3500 HD, and Ram dropped all the pertinent specs with the reveal. Chevy followed with the new Silverado HD in Chicago, and Ford revealed updates to the Super Duty at the same show. Ford hasn't released details on output, payload capacity, towing capacity or pricing for the updated Super Duty. As such, we'll be comparing the current Super Duty with the all-new Silverado HD and Ram HD. Both Chevy and Ram have revealed full specs for each of their respective trucks, leaving out only pricing, which we've estimated based on the outgoing models. You can see the raw details in the chart below, followed by extra information and analysis. Some things to keep in mind: These specifications cover all versions of the Ram HD, Silverado HD and Super Duty, such as 2500 and 3500 models, and all the way up to F-450. Specifications can vary widely based on engine, drivetrain, cab and bed configurations, so be sure to take a close look at the specific model you're interested in when you get particularly serious about buying. And of course, be sure to check out our car comparison tool if you'd like to look at other trucks on the market. Engines and drivetrains All three of these trucks offer gasoline and diesel engines, but only the Ram has two versions of the diesel. Starting with gas engines, Ram's 6.4-liter V8 has the power advantage with 25 more horsepower than the next-most-potent Super Duty, but the new Silverado HD's 6.6-liter V8 takes the torque crown at 464 pound-feet, nearly 35 more than the other two gas engines. The Ram is also the only one to pair an eight-speed automatic with the gas engine, whereas the Ford and Chevy make do with a six-speed. With diesel engines, horsepower is a weak point for the Ram. The Ram's entry-level turbo 6.7-liter inline-six is the weakest, as the only one with under 900 pound-feet of torque and under 400 horsepower. Even the high-output version only makes 400 horsepower, while the Chevy makes 445 and the Ford 450. But the tables turn with torque, as the Ram makes a best-in-class 1,000 pound-feet followed by the Ford's 935 and the Chevy's 910. Both the Ram and the current Super Duty diesels each get a six-speed automatic, but the new Silverado HD's diesel gets a 10-speed unit.

Chevy Volt has worst sales month since August 2011, Nissan Leaf also down

January is traditionally a time when new car shoppers take a break. For the last few years, if we isolate our focus to just the first two major plug-in cars in the US market, we see that the first month of the year was lower – often dramatically lower – than the 11 that followed. So, when you see the Chevy Volt dropped and Nissan Leaf sales figures for January 2015, don't be too surprised. The Volt sold only 542 units last month, that model's lowest since August 2011. That also represents a 41 percent drop from January 2014, and it reinforces the thought that if anyone out there is interested in a new Volt, they're going to be waiting for the new model to drop later this year. While we do expect sales to climb in February and into spring, we won't be surprised if the general Volt trend remains quiet until the second-generation arrives. On the Leaf side of the ledger, January's low sales numbers were still about twice as high as the Volt's – the Leaf sold 1,070 units last month, the lowest since February 2013 – but it did break a streak for the Japanese automaker. Usually, each month represents at least an increase over the same month a year ago, but that wasn't the case this time. In January 2014, Nissan sold 1,252 Leafs. Still, Brendan Jones, Nissan's director of electric vehicle sales and infrastructure, issued an upbeat statement: "We saw a significant increase in demand in December from Nissan Leaf customers looking to take advantage of federal and state incentives at the end of the tax year, which pulled some sales ahead. We're confident that EV sales will continue to rise over time due to increasing emission regulations and other reasons for purchase of EVs such as lower operating costs, reducing dependence on foreign energy sources, environmental concerns and a great driving experience." The numbers will tell us soon enough. News Source: General Motors, Nissan Green Chevrolet Nissan Electric Hybrid ev sales brendan jones
