To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Recharge Wrap-up: Audi R18 e-tron Quattro wins WEC opener, Toyota Mirai goes to DC

The Audi R18 e-tron Quattro has won the World Endurance Championship season opener at Silverstone. Drivers Marcel Fassler, Andre Lotterer and Benoit Treluyer piloted the number 7 hybrid racecar to a hard-fought win in the six-hour UK race. "This victory is a dream start of the season and a great reward for the whole squad for the hard work last winter," says Audi Motorsport boss Dr. Wolfgang Ullrich, congratulating the team. Audi's second R18 took fifth place in the race after a couple of unscheduled pit stops ate up precious time. Read more in the press release from Audi, below. Mini and Spanish designer Jaime Hayon are presenting new versions of the Mini Citysurfer electric scooter concept at Salone del Mobile in Milan, Italy. The installation, called "Urban Perspectives" depicts an idea of the future of urban mobility. The imaginary living space houses two examples of the Citysurfer concept designed by Hayon. The first is painted to resemble blue and while porcelain, with dots and stripes to give it an upbeat look. The second uses more upscale materials like anodized metal, copper and leather to blend modern and classical elements. The foldable Citysurfer scooter can travel 10 to 15 miles on a charge, and is designed fit and charge inside the trunk of a Mini Cooper. Read more from Mini. Tesla has announced the locations of its first Superchargers in Australia. It will install eight charging booths at the Goulburn Visitor's Centre, about 120 miles southwest of Sydney. The Goulburn superchargers will be powered by renewable energy. Tesla plans to install a network of Superchargers in cities along the route connecting the Sunshine Coast north of Brisbane south to Melbourne. Read more at Clean Technica. The Toyota Mirai will be on display at the National Mall in Washington DC to celebrate the 45th anniversary of Earth Day. Toyota is a sponsor of Global Citizen 2015 Earth Day from April 17 to 19, which will include speakers, musical performances and, of course, Toyota's new hydrogen fuel cell car. "Earth Day 2015 is a great platform to educate the public about hydrogen fuel cell technology and the potential of hydrogen as a future fuel," says Toyota's Bob Carter. Also in April, Toyota will continue to enlighten the public about the Mirai and hydrogen technology in Union Square Park in New York on April 19, and at Waterkeeper Alliance's "Keep it Clean" comedy event in Los Angeles on April 22.

2016 Audi A3 Sportback E-Tron First Drive

While its parent company is still in the throes of an emissions scandal that has thrust the "green" credentials of automakers worldwide under the microscope, Audi is launching its first plug-in hybrid in the US. Audi is ready to double down on its electrified future, putting up its own reputation as collateral. This A3 Sportback E-Tron – a vehicle we've sampled in prototype form – is a tech-savvy plug-in car that could be the perfect vehicle to mark the brand's new commitment to an electric lifestyle. Straightaway, Audi USA President Scott Keogh addressed the TDI situation. He says he and the rest of the company are "shocked, followed by appalled, followed by anger, and now in the phase of drop-dead determination to make this thing right." Out of the 500,000 affected 2.0-liter TDI engines around the world, 14,000 are in Audis: about 3,000 A3 TDI sedans and about 11,000 A3 TDI Sportbacks. "It's quite simple. CARB and the EPA have told us these cars can stay on the road, they will stay on the road until we have a fix, and when we have a fix, we will absolutely fix these cars." The most important thing going forward, Keogh says, is regaining the trust of both the dealers and customers. Audi has been enjoying a bit of momentum in recent years, building a reputation for itself along the way. Audi came on the scene in the US in 1969, but it took until 2010 for the company to sell 100,000 units in a single year. Now, "In 2015, we're starting to look down the barrel of nearly doubling our sales in five years," says Keogh. The A3 achieves a 40-percent segment share, and for 75 percent of those buyers, it is their first purchase of a luxury brand. But as its own pace increases, the momentum of the industry as a whole has pulled Audi toward this foray into electromobility. Enter the A3 Sportback E-Tron. There's a little extra weight from the battery pack, but the suspension does a good job of keeping it unnoticeable while driving. The A3 E-Tron has several strengths working in its favor. First of all, as Keogh puts it, the hatchback is a "real, proper Audi – a real, proper, fully rounded driving machine." Qualifications such as "this is an electric car" don't matter. "People just want to buy a car," he says. It has the technology, build quality, and drivability of an Audi.
