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.

2016 Chevy Volt arrives with 50-mile EV range, 41 mpg [w/ video]

Let's start with the numbers. The 2016 Chevy Volt will have an all-electric range of 50 miles from a new, 18.4-kWh lithium battery. It will get 41 miles per gallon (combined) once the battery runs dry and have 102 MPGe. Oh, and it has five seats, sort of. To compare, today's four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements. Now that that's out of the way, let's talk story. General Motors will unveil the new Volt at the Detroit Auto Show later today, but it's been talking about how this new version – the first major plug-in hybrid vehicle to get a serious redo in the modern era – was crafted with reams and reams of data from first-gen Volt customers. At a preview event for journalists last week, GM executive chief engineer Pam Fletcher told Autoblog that these owners "gave us the recipe" to make the second-gen model. At the top of the request list was more range (check), more "fun-to-drive" behavior (check?) and a smoother and quieter experience (we'll assume a check here, given that the new 1.5-liter four-cylinder – the first North American application of this new engine family – should offer more power with less noise than the previous 1.4-liter, four-cylinder powerplant). Other customer-driven changes in the new Volt include a different place to store the charging cable (in the side of the trunk instead of under the load floor) and a new brake system with improved blended regenerative braking feel as well as driver-selectable regen levels. The requested 50-mile range comes from a new, lighter battery that has increased capacity from fewer cells (192 vs. 288) and a simplified control architecture. Along with the new battery, the electric drive unit is a two-motor deal that is up to 12 percent more efficient and 100 pounds lighter, while also being "tremendously smaller," notes Fletcher. It offers 294 pound-feet of torque and a maximum 149 horsepower of "motoring power" delivered to the wheels. GM says it has worked hard to reduced the amount of rare earth materials in these motors, and one of them doesn't use any at all. The new powertrain offers improved acceleration times, as well. The 2016 Volt can go from 0 to 60 miles per hour in 8.4 seconds, a seven-percent improvement, while the 0-30 mph time has been improved by 19 percent, down to 2.6 seconds. The new Volt is more conventional looking, but certainly not completely ordinary.

2014 Corvette Stingray meets Tesla Model S in drag strip showdown

They come from two different worlds and have little in common. The Tesla Model S P85 is the sportiest version of this paradigm-punching sedan from California, while the 2014 Corvette Stingray Z51 is a performance-enhanced version of Michigan's recently-updated sports car stalwart. The West Coast car seats five adults and eats electrons like Popeye eats spinach, the Easterner has two passenger places and, surprisingly, sips gasoline like one might bourbon. An attribute they do happen to share is extreme quickness. This similarity is all the excuse Drag Times needed to set the vehicles beside each other at the Palm Beach International Raceway for a bit of mano-a-mano quarter-mile combat. Fortunately enough, cameras were rolling for each of two bouts down the blacktop and the results recorded for our edification and enlightenment. The winner? We won't spoil it for you, but let's just say it's really, really close. How close? Scroll below and watch the video for yourself. Just be warned, the results may surprise you.
