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 Australia price cuts in excess of $36,000 irks customers

Have you ever gone to the store, only to become irked after learning that the new [*insert widget here*] that you bought just last week has gone through a price drop? If you're particularly thrifty, even if it's only a couple of bucks, you probably brought in your receipt to see if the store would issue you a credit for the difference. Now, imagine that the widget in question isn't a minor purchase, it's a Porsche - and the price drop isn't just a few bucks - it's thousands.
That's the unhappy scenario that recently faced a number of Australian luxury car buyers and the uncomfortable conversation awaiting the German automaker. According to GoAuto, Porsche Australia recently whacked up to $36,000 off the price of its models in order to jumpstart sales Down Under - the Panamera range itself saw cuts between $5,500 and more than $36,000. The aggressive price cut was a strategy designed to drive sales of more than 3,000 cars locally, a yearly goal originally set for 2018, but now hoped for as early as 2016.
Australia is known for its comparatively high car prices, so the dramatic price cuts were undoubtedly welcome news to potential Porsche shoppers. However, around 50 existing customers were understandably agitated by the reductions because they purchased their cars just before the adjustments took effect. Not only did they stand to lose out on the deals, they also had good reason to fear that their new cars' residual values would take a beating.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.
