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.

Upcoming Audi Q1 rumored to get high-performance SQ1 variant

The Audi Q1 isn't due for another two or three years, yet Auto Bild reports already that it will come in RS and SQ1 trims. According to the report, the RS Q1 will be powered by a 2.0-liter four-cylinder putting out 300 horsepower and 280 pound-feet of torque, putting it about 70 hp and 8 lb-ft beyond the next-most-powerful gasoline engine in the standard range.
Depending on how you like your gumption served, however, the first SQ1 - like its European SQ5 sibling - go the diesel route with a 2.0-liter TDI fitted with twin turbos for 231 hp and 368 pound-feet of torque. That's an improvement of 47 hp and 88 lb-ft over the most powerful diesel engine said to be offered on the regular Q1.
The report goes on to say that there should be g-tron (natural gas) and e-tron versions of the Q1, and buyers will get a deep toy chest of assistance packages to equip it with. Starting price in Europe is expected to be around 25,000 euros, which, if correct, would make it 4,000 euros less dear than the Q3 in Germany.

Audi Nanuk Concept likes Parcour, puts four rings on it

Without a doubt, one of the coolest (and weirdest) debuts from this year's Geneva Motor Show had to be the Italdesign Giugiaro Parcour concept. And ever since the off-road performance coupe with Lamborgini guts made its debut, we've sort of been smitten with it. We figured this neat two-door would be a one-and-done show car, but to our delight, the folks at Italdesign worked with Audi to create this, the Nanuk Quattro Concept, which makes its debut here at the 2013 Frankfurt Motor Show.
Unlike the original Parcour, the Nanuk ditches the high-revving Lambo-sourced 5.2-liter V10 in favor of a twin-turbocharged 5.0-liter diesel V10. That's a beast of an engine, and with 544 horsepower and 738 pound-feet of torque on hand, it means the 4,189-pound, all-wheel-drive Audi can scoot to 62 miles per hour in under four seconds. Of course, being a diesel, it's surprisingly efficient, and we're told the Nanuk can achieve up to 30 miles per gallon.
As much as we sort of hate the term, the Audi Nanuk is a proper coupe-crossover if we've ever seen one, and utilizes the automaker's next-generation adaptive air suspension (the Parcour had a different pushrod arrangement) that offers a range of almost three inches of height adjustment. There's also an integral steering setup, meaning the rear wheels can turn up to nine degrees in the opposite direction of the front rollers, improving maneuverability.
