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.

2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

GMC Sierra electric pickup previewed, will launch in Denali trim

An electric GMC Sierra Denali is coming, and this is our first look at the fully-electric pickup truck. It’ll be the second electric pickup from GMC, following the Hummer EV pickup that is about to launch. GMC didnÂ’t reveal much about the EV, but it did say that the electric Sierra will launch exclusively in Denali trim. That means you shouldnÂ’t expect to buy any cheaper versions of the truck in the immediate future. Denali is extremely popular among GMC buyers, though, so this being the exclusive offering probably wonÂ’t hurt GMCÂ’s sales prospects too badly. Beyond the trim, GMC also says the truck will be built on the Ultium platform, which is a given these days for new electric GM vehicles. As for the image and teaser video (see the video below), GMC gives us a fairly clear view of what the electric SierraÂ’s front end will look like. This content is hosted by a third party.

That shield is then flanked by a pair of giant LEDs that wrap around the edges of the top front corner. The turn signals are also previewed, as they blink in three-dot fashion on the front bumper. We can also see some fairly aggressive hood sculpting shrouded in shadow. And thatÂ’s about it. GMC says the electric Sierra will be fully revealed next year, but doesnÂ’t provide an exact date. We already know the electric Silverado is coming to CES in January, though, so we suspect many questions about the GMC version will be answered then. When the electric Sierra does come out, GM says it will be producing them at its assembly plant in Detroit and Hamtramck, MI. Related video: This content is hosted by a third party.
