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.

2017 Porsche 911 Turbo First Drive [w/video]

Remember when turbos were a big fat middle finger to the naturally aspirated status quo? The horsepower renaissance has seen the forced induction phenomenon go from badass add-on (Turbo 'Vette!) to battle cry for efficiency (Kia Optima Turbo). From econoboxes to high-end holdovers like Ferrari and Aston Martin, everybody's doing the turbo shuffle. But what does that mean for the gang from Stuttgart – and more importantly, the top-of-the-line 911 that has called itself Turbo since the mid-1970s? I spent a day in the 2017 Porsche 911 Turbo and Turbo S to find out. Now is a particularly fitting time to evaluate the latest iteration of the venerable Porsche 911 Turbo. Our scrutiny comes at a moment when standard-issue Boxsters, Caymans, and Carreras have finally adopted turbocharged platforms. The Turbo S has a top speed of 205 mph, marking the first time the model has crested the 200-mph barrier. Spoiler alert: Rather than radically transforming its long-evolved essence, the 2017 Porsche 911 Turbo has made incremental changes that makes it, well, more Turbo than ever. Horsepower for the Turbo and Turbo S climbs 20 each, to 540 and 580, respectively; 0-60 times drop to a scant 2.9 and 2.8 seconds, and these top dogs now have terminal velocities of 198 and 205 miles per hour, marking the first time the model has crested the 200-mph barrier. The forced-induction flagships have different engine hardware, another first for the lineup, with the S gaining larger turbo impellers and housings. A revised differential enhances the precision of power transfer, while the PDK dual-clutch transmission (the only gearbox available) gains a centrifugal pendulum for smoothness. The dynamic engine mounts now work harder for crisper response, and the variable damping rates have been extended at both ends for a wider range of settings. If you're a fan of hanging the tail out, you'll be pleased to know that a new Sport mode enables greater yaw angles. And if you dig indiscreet bursts of acceleration, there's now a Dynamic Boost function that preps the drivetrain for a little extra oomph by dropping down a gear and holding the throttle open to maintain turbo pressure, increasing torque from 487 to 523 pound-feet, and from 516 to 553 lb-ft in the S. Standard equipment now includes a Sport Chrono Package, camera-equipped parking sensor, and the Porsche Dynamic Light System. Engine flexibility is outstanding, allowing peak torque to start at only 2,250 rpm.
