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.

Volkswagen Group names Paefgen head of classics program

You may remember the name Franz-Josef Paefgen. Until recently, the German engineer and executive was head of both Bentley and Bugatti. Before that he was chief executive of Audi, after working for several years at Ford. He technically "retired" earlier this year, but like the cars he helped create, an executive like Paefgen could never really retire. So it should come as little surprise that the Volkswagen Group has named Dr. Paefgen head of its Classic program.
In his new capacity, Paefgen will oversee the historic automobile activities of the entire VW Group, including those of Volkswagen, Seat, Skoda, Audi, Lamborghini, and of course Bentley and Bugatti. It strikes us as a suitable semi-retirement for the man responsible in no small part for the Bugatti Veyron and Bentley Mulsanne, to name just two, and who was decorated in 2006 by the ACO as the "Spirit of Le Mans" for his contribution to endurance racing.

Audi A8 could spawn Mercedes-Maybach S600 rival

Five years ago, there was no middle ground for big luxury sedans. You either bought a $100,000 Mercedes-Benz S-Class, Audi A8, or BMW 7 Series, or you spent $225K on a twelve-cylinder Bentley Continental Flying Spur. But today, the market is changing. Bentley sells a V8-powered Flying Spur for around $200,000 and Mercedes is successfully selling a longer, twelve-cylinder, ultra-lux S-Class for $190,000. The middle ground is growing, and Audi wants in on the action. Audi is looking closely at the Mercedes-Maybach S600, according to Dr. Stefan Knirsch, the company's new technical leader. The company recently introduced a one-off A8 limo, shown above, although we'd imagine an S600 rival would be a more manageable size. "We are thinking about it," Knirsch told AutoExpress at the launch of the new SQ7. "The success of the extra-long version of the S-Class has got us wondering about whether there could be a business case for that in the future." Knirsch's comments raise a number of questions about a potential ultra-lux A8. Would it be longer than the A8L? The extra backseat space is a key part of the Maybach S600's appeal. What about the badge? Audi doesn't have a nameplate to rival Maybach to distinguish such an exclusive A8 from its more affordable siblings. Will the Audi offer more or fewer shades of black/silver than the S600? But the biggest question is what a bigger, more luxurious A8 could mean for the rest of the A8 range. As AE explains, Mercedes has done a remarkable job of fleshing out the S-Class range, with the normal sedan, Maybach, Coupe, Cabriolet, and their accompanying AMG variants. The Maybach S600 started that process – could an extra-large competitor kickstart Audi's full-size luxury expansion? The A8 has long been subject to gossip that it'd spawn an A9 Coupe (2014's Prologue Concept only fed that particular rumor mill), after all. Beyond hinting at a more luxurious A8, Knirsch expounded on another piece of exciting news: the next A8 will get Level 3 automation. That would mean full driverless ability "with the expectation that the human driver will respond appropriately to a request to intervene," according to the SAE's official definition. While Audi confirmed last year that the A8 could drive itself at speeds up to 37 miles per hour, Knirsch's more specific comments make it sound like the system could be even more advanced than originally thought.
