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.

Recharge Wrap-up: Ford steals Best Green Brand spot from Toyota, EV buyer survey goes online

Chevrolet is one of the Top Global Green Brands of 2014, according to brand consultancy firm Interbrand. Chevy ranks number 32 on the list, which cover brands across a wide variety of segments. The report measures brand perception and brand performance, and the gap between the two is small for Chevrolet. "The company is not only actively demonstrating its environmental commitment," says Interbrand CEO Jez Frampton. "It's communicating those efforts in an authentic way that resonates with customers." Chevrolet cites its Spark EV, Volt and Cruze models as reason for its green cred. This is the first time Toyota didn't take the top spot. Being 32nd is good and all, but other automotive brands ranked much higher than the Bowtie. Ford, Toyota, Honda and Nissan took the top four spots in the report, respectively, with BMW, Volkswagen and Mercedes-Benz all besting Chevrolet. The big takeaway here is that Ford topped the list. In the Top Global Green Brand list's four-year history, this is the first time Toyota didn't take the top spot. Ford was second on the list last year, and 15th in 2012. "Ford embodies everything the business of the future must be: efficient, visionary, flexible, adept at problem-solving, cooperative, and focused on creating shared value," Interbrand says on its website. "From unveiling a first-of-its-kind solar-powered vehicle, the C-MAX Solar Energi Concept, to partnering with peers across sectors to do the seemingly impossible - like creating bio-plastic out of tomato fiber with Heinz-Ford is showing us what's possible." It bears mentioning that Ford's most recent MPG adjustments came after the study was conducted. Ford is also making the news for its 1.0-liter EcoBoost engine earning International Engine of the Year for the third straight year. Awarded Best Engine Under 1.0 Liter, the turbocharged three-cylinder motor earned high praise from judges. "This year's competition was the fiercest yet, but the 1.0-liter EcoBoost continues to stand out for all the right reasons – great refinement, surprising flexibility and excellent efficiency," said International Engine of the Year co-chairman Dean Slavnich. "The 1.0-liter EcoBoost engine is one of the finest examples of powertrain engineering." The 123-horsepower engine powers the Fiesta 1.0-liter EcoBoost, and will be available in a version of the Ford Focus in the US later this year. See more about the award in the press release, below.

A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.
