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 919 Hybrid used 500 gallons of fuel to win Le Mans

After 395 laps and over 3,300 miles covered, Porsche claimed its record seventeenth overall win at the 24 Hours of Le Mans this year. Those, however, were only a few of the numbers that went into the German team's landmark campaign, the fourth one-two victory in the history of its assault on the endurance race. And now it has released some of the other mind-boggling figures behind its win. Over the course of 24 grueling hours of competition, the winning Porsche 919 Hybrid averaged a staggering 139 miles per hour, reaching a top speed of over 211 mph. Along the way, the winning car changed gears over 25,000 times. We can imagine the drivers worked up quite a sweat in a cockpit, whose temperature topped 80 degrees, with less than a quart of water to drink during each stint between pit stops – the longest of which lasted over ten hours. Little wonder that Mark Webber lost over six and a half pounds by the end of the ordeal. Naturally, pit stops played a huge part in the campaign, and the team – whose headcount topped 120 – carried out 90 stops (30 per car) over the course of the race. All told, the three cars went through 116 tires, each car had its oil refilled entirely, and the winning car alone swallowed up 500 gallons of fuel. And that's not even counting the energy recuperated by the electric component of the hybrid powertrain, which would be enough to power a family home for three months. Those are just some of the most notable figures, but they give us a pretty good idea of the enormity of the whole endeavor. Want to read more? There's a whole list of numbers in the press release below. Related Video: The 17th overall victory for Porsche at the Le Mans 24-Hours 395 laps to victory Stuttgart. On Sunday, 14th June 2015, the trio of Earl Bamber (NZ), Nico Hulkenberg (GER) and Nick Tandy (GBR) took the 17th overall victory for Porsche at the Le Mans 24-Hours. They were followed across the line by the sister car of Timo Bernhard (GER), Brendon Hartley (NZ) and Mark Webber (AUS). This made it the fourth one-two result for the brand after achieving this in 1971, 1987 and 1998. But there are more interesting facts and figures about the race. • The winning team completed 395 laps (5,382,82 kilometres). This year's race was only two laps short of the longest distance covered in Le Mans back in 2010. • The average speed of the winning Porsche 919 Hybrid was 224.2 km/h.

Porsche 911 and Nissan 350Z get smoked by unlikely hero

So a Nissan 350Z Procharger and a current Porsche 911 GT3 drive onto the Autobahn together - stop me if you've heard this one before - and they decide to race. We're not sure how much power the Z is packing, but the stock model topped out at 306 horsepower on the last year of its run in 2009. And if that's a stock GT3 then it will be rocking something like 475 horsepower. So the Z and the GT3 give it a racing go, and just as one of them starts to pull away they're both overtaken by one of the most unlikely dark horses you could imagine. It's a really short video and we won't spoil the surprise, so check it out above.
