GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

2016 Chevy Volt will have more EV range, bigger battery

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.

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
