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.

This is how the new turbo Porsche 911 Carrera sounds

We have our first audio sample of the turbocharged flat-six engine in the standard Porsche 911 Carrera. By way of reminder, the boosted 3.0-liter engines will put out 370 horsepower and 331 pound-feet of torque in entry-level guise, 420 ponies and 368 lb-ft in the S models. To our ears, it sounds good. Yes, it's a commercial, true, we don't know what audio trickery the agency whipped up during post-production. But the sound in the commercial is good. Besides, Porsche knows what it's doing. Every time the brand breaks one of the purist's laws, the 911 accelerates through the wailing and gnashing of teeth to sell better than ever. Heck, the company's own engineers tried to beat the 911 with the introduction of the arguably much better 928, and we see how that turned out. So no matter what we think of the commercial, we have a feeling the sound of the turbocharged standard 911 will remain the same mythical siren to enthusiast ears around the world. On top of that, the new coupe and convertible are quicker, faster, more powerful, and still come with a seven-speed manual transmission if you choose. Porsche might taketh away, but to make up for it they giveth and giveth and giveth. Check out the noises in the video above, and some more of the advanced features on the new 911 in the video below.

LaFerrari, McLaren P1, Porsche 918 and Agera R take to Assen

It's the show-down (sort of) we've all been waiting for. The battle of the hybrid hypercars from the performance powerhouses of Europe: Ferrari LaFerrari, McLaren P1 and Porsche 918 Spyder. No one publication has managed to get their hands on all three just yet, but this video has - and with a Koenigsegg Agera R thrown in for good measure.
The video was shot by our (unrelated) Dutch compatriots at Autoblog.nl at the TT Circuit Assen in the Netherlands. The track has played host to Champ Cars and all manner of racing bikes, but this could be the ultimate grid of actual production machinery that's ever lined up behind its start/finish line. Shame the weather was rainy and this unsurpassed array of supercars weren't really racing - more showing off for the crowds. But what a show it was. Scope out the footage in the video below.
