New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Paul Walker's daughter files wrongful death suit against Porsche [UPDATE]

UPDATE: This post has been edited to include a statement from Porsche. While police blamed the crash that killed Fast and Furious star Paul Walker and racecar driver Roger Rodas on excessive speed, Walker's daughter, Meadow, thinks Porsche is at fault. The 16-year-old has now filed a wrongful death suit against the German manufacturer to back up that allegation. According to legal documents obtained by E! Online, the suit alleges that the Carrera GT that Walker and Rodas died in "lacked safety features ... that could have prevented the accident or, at a minimum, allowed Paul Walker to survive the crash," with Porsche Stability Management being called out in particular. Federal motor vehicle safety standards didn't require new cars sold in the US to be equipped with electronic stability control until 2012. The suit focuses not only on the Carrera GT's lack of electronic safety systems and "history of instability and control issues," but on an allegedly defective seatbelt. It claims that upon impact, the belt "snapped Walker's torso back with thousands of pounds of force, thereby breaking his ribs and pelvis," and prevented him from exiting the car before it caught fire, roughly a minute and 20 seconds after the initial impact, according to TMZ. Soot found in Walker's windpipe supports the theory that he was alive and breathing when the fire started, the suit continues. Like the suit Roger Rodas' widow filed against Porsche in 2014, Walker's filing also alleges that the Carrera GT wasn't traveling at 80 to 93 miles per hour, as a police investigation concluded. But where Mrs. Rodas claimed the Carrera GT was going 55 at the time of the crash, this suit claims the hypercar was moving at 63 to 71 mph. That's a more manageable figure to be sure, and if true would have a serious impact on the way the car behaved, but it's still well above the road's posted 45-mph speed limit. "The bottom line is that the Porsche Carrera GT is a dangerous car," Meadow Walker's lawyer told TMZ. "It doesn't belong on the street. And we shouldn't be without Paul Walker or his friend, Roger Rodas." Porsche, meanwhile, has stood by the reports from the Los Angeles County Sheriff's Department and other authorities.

Aston Martin Valkyrie could beat that new Nurburgring record, Red Bull F1 boss says

During last weekend's Austrian Formula 1 Grand Prix, Race Fans asked Red Bull F1 team principal Christian Horner about the Aston Martin Valkyrie. The question was whether the coming hypercar, a collaboration between Red Bull and title sponsor Aston Martin, could beat the stunning lap record around the Nurburgring just set by the Porsche 919 Hybrid Evo. Horner's answer: "I'm not sure a Formula 1 car could actually do it, but I think that the Valkyrie — certainly the track version of the Valkyrie — could be a contender." That's a qualified endorsement, but it still counts as support merely putting the Valkyrie AMR Pro in the conversation. Let's compare, shall we? The 919 Hybrid Evo is based on the 2017 World Endurance Championship-winning 919 Hybrid. Freed from motorsport regulations, Porsche Motorsport upgraded numerous performance bits. The 2.0-liter, turbocharged V-four-cylinder went from 500 hp to 720 hp. The two KERS units went from 400 hp to 440 hp. We don't have a figure for downforce, but items like active aero, a larger front diffuser, optimized turning vanes, and larger rear wing increased downforce by 53 percent over the WEC car, at the same time being 66 percent more aero efficient. It weighs 849 kg dry, or 1,868 pounds because Porsche threw out everything that didn't contribute to speed. The Valkyrie specs we know of so far state a weight of 1,000 kilograms, or 2,200 pounds. Powering that is a custom, naturally aspirated, 6.5-liter AMR Cosworth V12 with more than 900 horsepower, augmented by a kinetic energy recovery system contributing around 230 hp. According to Autocar's sources, the Valkyrie could generate up to 4,000 pounds of downforce at an aerodynamically-limited 225 miles per hour. That boggling number comes courtesy of Adrian Newey's prowess at making changes such as openings between the front wheel arches and the cockpit that work the front wing harder. The two-seater coupe's unrestricted top speed is 254 mph. Note, though, that the Valkyrie AMR Pro will be more powerful, lighter, and could have even more downforce. And since Aston Martin and Newey continue to work on the hypercar, specs could get even better before deliveries begin. Right now, Horner's suggestion doesn't seem all that outrageous. We'll also wait to see if the Mercedes-AMG Project One pokes its nose in the ring, too. Not long ago, AMG chief Tobias Moers said it's "reasonable to speculate" the F1-inspired hypercar could claim an absolute lap record around the 'Ring.
