Are more diesel scandals about to erupt?

More automakers may soon be embroiled, like Volkswagen, in diesel emissions scandals. According to the Daily Kanban, either the International Council on Clean Transportation (ICCT) or the Deutsche Umwelthilfe (DUH) will soon announce from 10 to 15 more cases of automakers cheating national diesel emissions rules. The outlet says three of the incidents are attributed to Opel. Studies conducted by the DUH, the University of Applied Sciences in Bern, Switzerland, and the UK's Leeds University found that Opel's diesel Zafira, Corsa, and Vectra models emit more NOx than European regulations allow when tested in ways that go beyond the European testing protocol, such as when done on a four-wheel rolling road instead of a two-wheel rolling road. Opel said the accusations had no merit. Specifically on the Zafira, the DUH asked Opel about the emissions findings, and Opel said that no General Motors software contains any measures to enable cheating. Opel then tested a Zafira of its own "both on a two- and a four-wheel roller dynamometer," finding that "The emission behavior determined in each case does not differ from one another." That makes this a case of he-said-she-said for the moment. The Daily Kanban's sources say the cheating methods "range from the crude to the highly sophisticated," with those at the latter end complex enough to render Volkswagen's methods "pedestrian." As for any automakers who might be named, the matter of real-world emissions exceeding a legal limit doesn't mean a carmaker has designed systems that cheat, it might mean the company designed the car to pass a test.

Volkswagen to 'refit' 11 million diesel vehicles [UPDATE]

UPDATE: This post has been updated with an official comment from Volkswagen of America. In response to its devastating diesel-emissions scandal, Volkswagen will ask some 11 million of its customers to report into dealerships to have their diesel-powered vehicles "refitted," Reuters is reporting. According to new CEO Matthais Muller, customers will be asked to report in "in the next few days" for the refit, although it's not entirely clear exactly what the 'refit' entails. Mueller apparently made the announcement during a closed-door meeting with 1,000 of the German company's top managers, although he didn't explain exactly how the emissions-cheating software would be sorted out, or what impact it would have on the performance of mileage of the company's diesel-powered products. It's expected that the refit work will cost VW $6.5 billion, Reuters claims. "We are facing a long trudge and a lot of hard work," Muller allegedly said. "We will only be able to make progress in steps and there will be setbacks." Autoblog reached out to Volkswagen of America to see when American consumers would be asked to report to dealers, what the refit involves, how long it's expected to take to repair all the cars in the US and globally, and what impact this fix will have on the performance and fuel economy of its diesel-powered cars and SUVs. Unfortunately and unsurprisingly, VWoA wasn't too forthcoming. "We don't comment on media speculation on internal meetings," Volkswagen of America spokesman Mark Gillies told Autoblog, adding, "We don't have any information on what the remedy might be at the moment, but we are working on it as a matter of the utmost urgency."

Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.
