EPA discovers defeat device in more VW TDI engines

In a sternly worded letter, the United States Environmental Protection Agency has issued a new set of allegations against Volkswagen claiming that so-called emissions defeat software has been found in the company's 3.0-liter TDI V6 diesel engines. This is a completely different engine than the 2.0 TDI that has already been identified as an emissions cheater. In addition to VW, the EPA has included Audi and Porsche in this notification, as the non-compliant engine has been used in vehicles from all three manufacturers from model years 2014 through 2016. The EPA claims that cars equipped with the 3.0 TDI engine know when they are being tested for emissions, and their on-board computers switch into a mode designed to pass the stringent requirements in the United States for diesel exhaust. Vehicles sold in the United States with this engine include the 2014 VW Touareg, 2015 Porsche Cayenne, and 2016 Audi A6, A7, A8L and Q5. The EPA says there are 10,000 vehicles currently on the road with this second defeat device, along with an unknown number of 2016 models either on dealer lots or in the driveways of consumers. According to the EPA, VW's 3.0-liter TDI, like the 2.0 TDI that was found to circumvent US regulations, has code in its computer specifically written to intentionally put the vehicle's engine into a mode that allows it to meet exhaust requirements. When the vehicle is unhooked from testing equipment, it will go back into a mode that emits nine-times higher nitrogen oxide emissions than is allowable under US law. "VW has once again failed its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance. "All companies should be playing by the same rules. EPA, with our state, and federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, and to ensure consumers get the environmental performance they expect." Richard Corey, Executive Officer of the California Air Resources Board, said in a statement, "Today we are requiring VW Group to address these issues. This is a very serious public health matter. ARB and EPA will continue to conduct a rigorous investigation that includes testing more vehicles until all of the facts are out in the open." This story will be updated as new information becomes available.

VW apprentices prep Golf GTI Dark Shine, Variant Biturbo for Worthersee

Volkswagen not only cooks up some pretty tempting concepts of its own for the GTI-Treffen at Worthersee every year (and encourages its sister brands to do the same), but also gives its apprentices the opportunity to do it. And here's what they came up with this year. Called the GTI Dark Shine edition, the show car features an upgraded 2.0-liter turbo four, pumping out 389 horsepower and 359 pound-feet of torque through its dual-clutch transmission. But that's not all. As you can see, it also has a striking two-tone livery of metallic gray and yellow pearl, along with a stainless steel exhaust, carbon air box, an upgraded aero kit, a 3,500-watt audio system with eight speakers and a thoroughly reworked interior done up to match the bodywork in black Alcantara and carbon leather with yellow trim. The team of 13 apprentices built the show car from a body-in-white over the course of nine months. It follows in a long line of GTI concepts done each year by VW apprentices that stretches back to 2008. This year, however, another team of 14 interns at the plant in Zwickau, Germany, worked up a blue Golf Variant wagon called the Biturbo Edition with the twin-turbo diesel from the Passat good for 236 hp and 368 lb-ft. Another team in the Czech Republic was responsible for the Fabia FUNstar pickup concept. And of course the automakers themselves showcased the radical Golf GTE Sport, GTI Clubsport, Skoda Fabia Combi R5 and Audi TT Clubsport. The lake is calling ... world premiere: Volkswagen apprentices present their Golf GTI Dark Shine at Worthersee event - Other show car premieres: Golf Variant Biturbo Edition (Zwickau) and SKODA FUNstar (Mlada Boleslav) They have followed the call of the lake: 13 Wolfsburg apprentices from Volkswagen and group company Sitech Sitztechnik have traveled to the 34th Worthersee GTI meeting today to present their 395 PS (290 kW) Golf GTI Dark Shine to the public for the first time. Their sporty two-door Golf features a two-tone color scheme. The front is painted in dark Daytona Grey Metallic and the rear in unique R-yellow pearl effect – giving rise to the name "Dark Shine". The Golf GTI Dark Shine is impressive confirmation of the high-quality practically oriented training provided by Volkswagen.

Cruze Diesel Road Trip reveals the good and bad, but no ugly

Most of us have strong opinions on diesel-powered cars based on our perceptions of and experience with them. I used to thoroughly dislike oil burners for their noise, smoke and lackluster performance, and the fact that they ran on greasy, smelly stuff that was more expensive than gasoline, could be hard to find and was nasty to get on your hands when refueling. Those negatives, for me, trumped diesel's major positives of big torque for strong acceleration and better fuel economy. Are any of those knocks on diesel still valid today? I'm not talking semis, which continue to annoy me when their operators for some reason almost never shut them down. At any busy truck stop, the air seems always filled with the sound – and sometimes smell – of dozens of big-rig diesels idling endlessly and mindlessly. Or diesel heavy-duty pickups. Those muscular workhorses are far more refined than they once were and burn much less fuel than their gasoline counterparts. But good luck arriving home late at night, or departing early morning, without waking your housemates and neighbors with their clattery racket. No, I'm talking diesel-powered passenger cars, which account for more than half the market in Europe (diesel fuel is cheaper there) yet still barely bump the sales charts in North America. Diesel fuel remains more expensive here, too few stations carry it, and too many Americans remember when diesel cars were noisy, smelly slugs. Also, US emissions requirements make them substantially more expensive to certify, and therefore to buy. But put aside (if you can) higher vehicle purchase and fuel prices, and today's diesel cars can be delightful to drive while delivering much better fuel efficiency than gas-powered versions. So far in the US, all except Chevrolet's compact Cruze Diesel come from German brands, and all are amazingly quiet, visually clean (no smoke) and can be torquey-fun to drive. When a GM Powertrain engineering team set out to modify a tried-and-true GM of Europe turbodiesel four for North American Chevy Cruze compacts, says assistant chief engineer Mike Siegrist, it had a clear target in mind: the Volkswagen Jetta TDI 2.0-liter diesel. And they'll tell you that they beat it in nearly every way. "I believe we have a superior product," he says. "It's powerful, efficient and clean, and it will change perceptions of what a diesel car can be." The 2.0L Cruze turbodiesel pumps out 151 SAE certified horses and 264 pound-feet of torque (at just 2,000 rpm) vs.
