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.

Audi's Q8 Concept previews a 2018 personal luxury crossover

Audi revealed the Q8 Concept here at the 2017 Detroit Auto Show, and it's just as we expected: a Q7 with frameless windows, an oversized grille, and a rakish "coupe-like" roofline. This concept is an exaggerated example of a vehicle that will almost certainly enter production to do battle with BMW's vanity luxury utility, the X6, and Mercedes-Benz's GLE Coupe. The coupe moniker doesn't really apply, despite the German automakers' best attempts to redefine the word, but otherwise the Q8 Concept delivers. It's two inches shorter overall than a contemporary Q7, on a similar wheelbase, so the basic proportions of the thing should make the jump to production. View 14 Photos The driveline is equally plausible: a plug-in hybrid setup pairing a 3.0-liter TFSI V6 with a 17.9-kWh lithium-ion battery. The concept's V6 hypothetically makes 333 horsepower and 368 lb-ft of torque, and a single electric motor integrated into the eight-speed automatic transmission adds 100 kW (134 hp) and 234 lb-ft of torque to the mix. Those numbers certainly make sense, considering the gas Q7 makes 333 hp (albeit with a supercharger) and the existing Q7 e-tron, which isn't sold here, pairs a 17.3-kWh battery with a diesel V6. Since this is a concept, production intent or no, the range numbers are also a little theoretical, but here's what Audi claims: a 60-mile EV range, and a total range of around 621 miles. Not shabby if you're taking a long road trip. The adaptive air suspension should also make it a comfortable one. Inside, this is a four-place vehicle; no third row, and no center rear seat, as is the trend with these things. The cabin is very clean and modern – typically Audi, although exaggerated a bit. Expect it to be toned down some for production, but this concept interior is a glimpse into the future. We'll have to wait until next year to see something closer to production-ready, but it's coming.

The head of Audi powertain development is quitting as the automaker steps up electrification. Stefan Knirsch has worked at Audi since late 2013, and previously worked at Porsche as the head of quality management and engine development. Germany's Auto Motor und Sport magazine had reported that Knirsch was leaving Audi, which Audi confirmed without giving a departure date or saying if he would be working elsewhere. Audi has been feeling pressure from its competitor Mercedes-Benz, and has been working on improving its EV offerings and autonomous vehicle technology. Read more from Reuters. The owner of a biodiesel company has pleaded guilty to fraud. Philip Joseph Rivkin, aka Felipe Poitan Arriaga, took part in a scheme to defraud the EPA, falsely claiming to be producing millions of gallons of biodiesel. This allowed his company, Green Diesel, to receive renewable fuel credits and sell them to oil companies and brokers. "These crimes are a serious threat to an important program that helps combat climate change," says Cynthia Giles of the EPA. "Companies and individual managers should get the message that there are serious consequences for breaking the rules and undermining the integrity of this program." Rivkin faces over 10 years in prison and $51 million in restitution. Read more in the press release below.
