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.

Porsche Pajun to go all-electric as Tesla rival

Porsche has been rumored to be working on a smaller counterpart to the Panamera for nearly four years now, but we have yet to see any sign of the model dubbed Pajun coming to fruition beyond a digital rendering hidden in the background of another Porsche design. Apparently Stuttgart has been having trouble making the business case in an already crowded market segment. But that doesn't mean the project is completely off the table. According to the latest from Germany's own Auto Motor und Sport, Porsche is now planning to launch the so-called Pajun (shorthand for Panamera Junior just like the Macan project was previously called Cajun) purely as an electric vehicle. With an eye evidently fixed on how dedicated hybrids and EVs are gaining traction in the marketplace (to say nothing of actual tarmac), the electric Pajun - almost certain to carry a different name to the showroom – would be different enough to distinguish itself from existing four-doors of that size like the Mercedes E-Class, BMW 5 Series, Audi A6, et al. Word has it that Porsche believes that battery technologies will advance enough over the next four years to give its four-door EV a range of nearly 250 miles on a single charge. The model's arrival would be just the latest in a series of environmental concessions made by the company with the broadest range of plug-in hybrids on the market. Aside from the E-Hybrid versions of the Panamera and Cayenne, Porsche arguably led the charge (so to speak) towards hybrid hypercars with the 918 Spyder, is downsizing many of its engines and is turbocharging almost the entirety of the 911 range.

Porsche 919 Hybrid collides with 911 at Silverstone

Endurance racing is tough, in part because drivers must share the track with a whole variety of cars traveling at different speeds. That can be especially difficult for the front-running prototypes, which have to keep up the pace while overtaking slower cars. Just ask Brendon Hartley, whose spectacular crash in a Porsche 919 Hybrid while overtaking a 911 thankfully resulted in no injuries. The defending champion was scything his way through lapped back-traffic in the season opener this past weekend for the FIA World Endurance Championship when he apparently miscalculated a passing maneuver while exiting the corner. Hartley was reprimanded for the collision that took both cars out of the race but fortunately left both drivers unscathed. Worse yet was that he and his teammates were on track to win the race, and ended up watching the rest of the race from the pit lane. Instead an Audi R18 crossed the finish line first – but the race win was subsequently handed instead to another Porsche 919 during post-race scrutineering. Audi is appealing the decision, but Hartley and his co-pilots Timo Bernhard and Mark Webber will have some ground to make up if they hope to retain their crown this season.
