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:

2014 Volkswagen XL1 [w/video]

World's Most Efficient Car Impresses, Not Without Compromises
Among our many duties at the recent Geneva Motor Show, we were offered a pretty exclusive drive in the new Volkswagen XL1 hyper-efficient plug-in diesel hybrid. There is so much that is interesting about a car like this reaching production from a major automaker that it's tough to know where to begin.
First off, you should know that - at least for this generation - there is absolutely no chance in Albuquerque that this "1-liter vehicle" (i.e. a vehicle that can burn just one liter of fuel to travel 100 kilometers, or 62.1 miles) will ever make it into the hands of North American customers. We, too, were having trouble imagining an XL1 in typical American traffic, surrounded by comparatively massive pickups and SUVs. The driving experience had us recalling a couple of weeks in 1999 when we drove the then-revolutionary Honda Insight hybrid on US roads. We keenly remember the feeling of being very small and vulnerable, even as we felt proudly green in our 61-mpg Tochigi pod. Thing is, the Volkswagen is smaller still, and nearly as light despite its more complex drivetrain and safety features.

Next-gen Volkswagen Golf R spied while running the 'Ring

The launch of a new Volkswagen Golf is never a small thing, and things are already looking up for the subcompact hatchback after it was named 2013 World Car of the Year. While we've already seen the base and GTI versions of the next-generation Golf, now we're getting our first look at the sportier Golf R.
Although this prototype wears GTI lettering on the front fenders, it's more than just the roll cage and Sparco racing seat hinting that this is something a little more serious. Unlike the Golf and GTI, this car shows that the Golf R will continue to flaunt massive air intakes on each side of the fascia, and the rear of the car (though it's hard to see) has quadruple exhaust outlets. We still don't have an official word on power, but rumors indicate that the next Golf R could be pushing close to 300 horsepower, making it the most powerful production Golf ever. As much fun as we had during our first drive of the Golf R Cabriolet in the cold, snowy French Riviera last month, more power is a warming idea.
