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.

2015 Porsche Macan Turbo

The misinformation first started back in May of 2007 - more than six years ago - when word came that Porsche was developing a compact utility vehicle to fill out its product line. Rumors swirled that the German automaker's future "Roxster" would be based on the then-upcoming Audi Q5. By September of 2010, the name had changed to "Cajun," but the vehicle was still expected to be "based heavily on the Audi Q5," said reports in the months that followed. One year later, the first test mules were spotted, the mechanics hidden beneath barely disguised Audi sheetmetal, which did nothing to give the upcoming model its own identity. And even after Porsche announced "Macan" as the vehicle's production name in early 2012, articles stated that it would "arrive on the same chassis as the Audi Q5, though with suspension, brake and engine tweaks suitable to the Porsche range."
It's no wonder that most still consider the all-new Porsche Macan nothing more than a heavily massaged Q5.
To help lift some of the mystery surrounding its latest release, Porsche hosted us in Germany for an in-depth look at its new crossover (while Europeans call it a "sport utility," its car platform allows us to call it a proper CUV). The technology workshop offered us insight to the design and mechanical execution, and it concluded with a short test ride. The trip was both enlightening and educational - and it left us with a whole new perspective on the Macan.

Volkswagen Group previews its wares on eve of Geneva show

The Volkswagen Group is comprised of 11 brands producing 240 vehicles across 49 factories throughout the world. So the best way to show off the range of the VW family is to cram a few thousand journalists and VIPs into a massive makeshift stand to outline the Group's goals, what's in the pipeline and what you'll be able to buy later this year.
To that end, VW pulled out all the stops on the eve of the 2012 Geneva Motor Show, bringing along 10 vehicles from across the range. We'll be delving into the details of each over the next two days of show coverage, but before that happens, you can read all about what we saw tonight from the cheap seats after the break.
