GM is the latest automaker accused of diesel emissions cheating

Volkswagen and Ram need to make room on the diesel-emissions bench for General Motors. America's largest automaker was accused in a lawsuit on Thursday of rigging hundreds of thousands of diesel trucks with at least three so-called defeat devices to ensure that the trucks would meet federal and state emission standards, even if they generated more pollution in real-world driving. According to the complaint, on-road emissions testing conducted for the plaintiffs found that Duramax-equipped trucks produced NOx pollutants, comprised of nitrogen and oxygen atoms, two to five times higher than legally permitted, and "many times" higher than their gasoline counterparts. The proposed class-action lawsuit was filed in federal court in Detroit on behalf of people who own or lease more than 705,000 Chevrolet Silverado and GMC Sierra pickup trucks fitted with "Duramax" engines from 2011 to 2016 model years. The lawsuit seeks remedies including possible refunds or restitution for lost vehicle value, plus punitive damages. It adds to legal problems for Detroit-based GM, which has already paid about $2.5 billion in penalties and settlements over faulty ignition switches linked to 124 deaths. GM joins at least five automakers whose diesel emissions have been scrutinized by regulators or consumers. They include VW, which has admitted to cheating; Mercedes-Benz parent Daimler; Fiat Chrysler Automobiles, Peugeot and Renault. GM spokesman Dan Flores called the claims "baseless," and said the trucks comply with US Environmental Protection Agency emissions standards and California's own tough standards. Shares of GM were down 69 cents, or 2.1 percent, at $32.50 in afternoon trading, after earlier falling to $31.93. The GM lawsuit was filed by several law firms, including Hagens Berman Sobol Shapiro, which helped reach multibillion-dollar settlements with VW on behalf of drivers and dealers. The case is Fenner et al v General Motors LLC et al, US District Court, Eastern District of Michigan, No. 17-11661. The named plaintiffs are Andrei Fenner of Mountain View, California and Joshua Herman of Sulphur, Louisiana. They said they would not have bought their respective 2011 Sierra and 2016 Silverado trucks, or would have paid less for them, had they known about the alleged rigging. Joseph Spak, an RBC Capital Markets analyst, in a research report said "negative publicity" from the lawsuit could drive buyers to trucks from Ford or even Fiat Chrysler's Ram.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

Recharge Wrap-up: Chevy Volt's new, improved powertrain; Inabikari wants to build Tesla Model X fighter

We knew the 2016 Chevrolet Volt's new powertrain would provide more range, but we didn't know how much. According to GM's Executive Director Larry Nitz, it is about 12 percent more, overall. "I can't think of a powertrain we've re-engineered more extensively within a five-year period than this one," he said. The battery, electric drive system and gasoline generator have all been reworked to allow for an overall driving range of up to 425 miles, with electric range speculated to reach 42 miles or more. The new Volt will also benefit from 20 percent quicker low-end acceleration, weight reductions and improvements in NVH. Read more at Hybrid Cars and at the SAE website. Hyundai's FCEV research and development boss, Dr. Sae-Hoon Kim, is optimistic about the future of hydrogen mobility in Japan. With the Tucson Fuel Cell already in production ahead of Toyota's FCV, Hyundai has a foothold in the hydrogen car scene. Kim believes that since the Fukushima disaster, Japan's attitudes toward energy make it friendly to a growing hydrogen economy. He also says that hydrogen won't be limited to Hyundai, with Kia getting all the battery EVs. "Both types are for both companies," Kim says. "For the moment, volumes are small and it is not wise to have Hyundai and Kia competing." Read more at Just Auto. The Latvian/German startup Inabikari is using crowdfunding to build an electric crossover for Europe. The Rev.01 EV hopes to compete with Tesla's upcoming Model X with a range of over 400 miles and a five-second 0-60 time. The group currently is trying to raise initial funds through an Indiegogo campaign, with hopes of more investment in the future and sales beginning in 2017. See the video below, and read more at Hybrid Cars and at the Inabikari website. Fuel economy and emissions regulations could lead to some interesting design changes to automobiles. The World Light Duty Test Procedure, set to replace the New European Driving Cycle in 2017, will push automakers to find new ways to reduce drag on their vehicles. For better aerodynamics, we could see traditional side-view mirrors replaced by cameras that display what they see on screens inside the vehicle. Another likely change will be the introduction of smaller, narrower wheels. Improving the average drag coefficient from 0.32 to 0.20 could reduce CO2 emissions by as much as 20 percent.
