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:

Porsche would have entered F1 if Audi had blocked its Le Mans program

Go back a few years and you may have heard rumors of Porsche heading into Formula One. That never came to pass - or at least, it hasn't yet - but that doesn't mean that it wasn't close to happening. That's how committed to returning to top-level motorsport competition Porsche has become recently.
Autosport reports that just as Porsche was merging fully into the Volkswagen Group, Zuffenhausen was weighing its options for a factory racing program. Le Mans was its favorite, which makes sense, as it remains far and away the most successful constructor in the history of the famous endurance race. But the strategists at Porsche were worried that its new corporate overlords at Volkswagen wouldn't support two LMP1 programs and would favor Audi, which has positively dominated the modern era of endurance racing, coming second only to Porsche in the number of Le Mans victories it has scored to date.
Porsche's Plan B was reportedly to head into Formula One, although it isn't clear if the German automaker was intent on starting its own team, buying an existing one or merely providing engines to other teams. Porsche fielded its own cars in F1 in the late 1950s and early 60s, and returned as an engine supplier with TAG to power McLaren in the 1980s, powering Niki Lauda and Alain Prost to the World Championship in 1984 and 1985.

Porsche's latest Driver's Selection keeps enthusiasts happy at home

Porsche fans - and there are certainly plenty of them out there, even in here on the Autoblog editorial staff - can be pretty emphatic about their enthusiasm, insisting that the 911 is the very definition of the sportscar. And for some, merely admiring one from afar or even leaving theirs parked outside isn't enough. For just such enthusiats, Porsche Design has expanded its Driver's Selection with some tantalizing additions for the home and office.
First up is a desk chair made from the bucket seat in a 911 Carrera, which we have to admit we'd rather be sitting in right now over this blasted, rather unexciting ergonomic office chair. It's covered in black leather (the same you'd find inside an actual 911) embossed with the Porsche emblem and features electronic backrest adjustment.
There's also a wall shelf made from the carbon-fiber rear spoiler a 911 GT3 Cup racecar that can support up to 264 pounds of downforce in the form of books, trinkets and whathaveyou. And there's a limited-edition resin model of the 918 Spyder in 1:8 scale. The items haven't hit the Porsche shop just yet, so we don't have pricing information, but if they tickle your fancy, the online store has plenty more to offer.
