West Virginia researcher describes how Volkswagen got caught

The cheating scandal engulfing the world's largest automaker started with a road trip. In the spring of 2014, researchers from West Virginia were evaluating the tailpipe emissions of diesel cars made for the American market by European manufacturers, something never before studied in the academic realm. Excited by the prospect of breaking new ground, the team of two professors and two students wanted to gather as much data as possible. "And being academics, we went a little overboard," said Arvind Thiruvengadam, one of the students. "Being academics, we went a little overboard." Overboard included driving the cars for more miles than they needed to test and verify results. Drivers put about 1,500 miles on each of the first two cars in the study, a Volkswagen Jetta and BMW X5, along California roadways. For their final car, a Volkswagen Passat, they wanted even more mileage. So they took the car on a road trip from Los Angeles to Seattle and back again, collecting data from more than 2,000 miles of testing. The road trip was Volkswagen's undoing. When the West Virginia team returned to Los Angeles, they were befuddled by the test results. In theory, the Passat should have spewed the lowest levels of pollutants among the three cars. Equipped with the more modern selective catalytic reduction technology, the team expected to find minimal levels of nitrogen oxide. But the car, which had been certified at a California Air Resources Board facility prior to the start of the road trip, had elevated levels of NOx that were 20 times the baseline levels established beforehand. The researchers, comprised of professors Gregory Thompson and Dan Carder and students Marc Besch and Thiruvengadam, knew their on-board equipment functioned properly because, early in their research, they had double-checked its accuracy after recording sky-high NOx readings from the Jetta that showed 30 times the level of its baseline testing at the CARB facility. It was particularly noteworthy because the Jetta contained the first-generation Lean NOx Trap technology, not the more efficient SCR, yet both produced large discrepancies. The BMW, on the other hand, performed as expected. Today, Thiruvengadam is careful to say the research team never suspected Volkswagen of cheating on emissions testing, nor did the researchers report such a finding. They merely reported their findings to CARB officials who then further investigated.

Volkswagen's new Passat Alltrack ready to scale the Alps

Volvo may be stepping up its off-roading game with a greater variety of Cross Country models tumbling out the factory in Gothenburg, but the other (larger) European automaker whose name starts with the letters V-O-L is also broadening and updating its range of road-going automobiles equipped to handle a little soft-road duty. Aside from Audi's Allroad line, Skoda's Scout models and the new Seat Leon X-Perience, the Volkswagen brand itself has recently showcased Alltrack versions of the Golf, Multivan and of course the Passat. And now it's announced a new version of the latter for the European market. Based on the Euro-spec Passat Variant, the new VW Passat Alltrack follows a familiar formula: take a station wagon, equip it with all-wheel drive, jack up the suspension, add some lower body cladding and some new trim and – voila! – you've got a pseudo rough-roader on your hands. Set to debut in just a couple of weeks from now at the 2015 Geneva Motor Show, the new Passat Alltrack is visually distinguished by its new bumpers, underbody protection, beefed-up wheel arch moldings and a ride height increased by over an inch to the benefit of ground clearance as well as approach and departure angles. European buyers who like to leave the road every once in a while (or give the impression that they do) will be able to choose from a range of five engines: two burning gasoline with either 148 horsepower or 217, and three diesels available in 148-, 187- or 237-hp states of tune. The base TSI and TDI engines are mated to a six-speed manual, while the top three are hooked up to a six-speed DCT, but they all come with 4Motion all-wheel drive as standard. All but the base TSI model boast a towing capacity of 1,800 kg, enhanced by a Trailer Assist system that automatically lines the vehicle up to a trailer. It even comes equipped with an off-road mode that incorporates Hill Start Assist and Hill Descent Assist to make any journey across the Alps a breeze.

Recharge Wrap-up: Volkswagen Sustainability Council meets, Zee.Aero flying car spotted?

The Volkswagen Sustainability Council held its inaugural meeting in Berlin. Made up of nine international experts, the council will advise VW and take action on its own as it sees fit. In the meeting, the council decided that in 2017 it will focus on tackling CO2 emissions, planning for post-2025 regulations, and assisting the automaker's "transformation from car manufacturer to mobility services provider," as VW Chairman Matthias Muller puts it. Volkswagen has approved 20 million euros (about $21.75 million) in funding for Sustainability Council projects for its first two years. "We are fully aware of the large transformation that lays ahead Volkswagen Group," says George Kell, Sustainability Council Chair and Founding Director of UN Global Compact. "We were invited to be part of this journey and are very much looking forward on being actively involved in the development of this journey." Read more at Green Car Congress, or from Volkswagen. Honda plans to ramp up its share of hybrids sold in the US. In response to increasingly strict emissions standards, the company wants electrified vehicles (including hybrid, plug-in hybrid, battery electric, and fuel cell vehicles) to make up two-thirds of Honda and Acura sales in US by 2030. Some analysts are skeptical, though. Christopher Richter of CLSA Asia-Pacific Markets says that dealers are telling Honda they don't want hybrids. "Unless there's a change in what dealers want, I don't think they are going to get there that fast," Richter says. Read more at Automotive News. Witnesses report spotting what could possibly be the Zee.Aero electric aircraft at Hollister Airport in California. Zee.Aero, a startup funded by Google cofounder Larry Page, has a hangar at that airport, where a photo was taken of the aircraft in question. The craft is said to be capable of vertical takeoff and landing and can fit in a one-car garage, earning it the "flying car" moniker. Eyewitness Saul Gomez described the aircraft as "quiet" and "hovering 20, 25 feet off the ground." Read more at Electrek, and watch the interview at Mercury News.
