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 911 R is made for the purist

Who wouldn't welcome a new version of the Porsche 911 with ultra-light weight, a GT3 RS motor, a stripper interior, and a core philosophy of driving fun over outright lap times? The iconic Porsche 911 has been getting larger and more complicated with each passing generation, and that hasn't sat well with every engineer at Porsche. So there's a ready market out there for 911 R, a limited-edition show stopper of just 911 cars, due to start production in Zuffenhausen, Germany, in May. It's a car that combines a unique version of the six-speed manual gearbox, plenty of raw, naturally aspirated flat-six power, and all the feel of a cut-price version of the 911 GT3 RS pseudo racer. Yes, Porsche is bringing the beloved six-speed stick back to the sharp end of the 911, even though the brand's quickest cars are now dominated by the seven-speed dual-clutch transmission (and the less loved seven-speed manual). Porsche insists that the RS is still the 911 to have if it's stopwatch-bashing you need to do. Instead, the 911 R developers focused on trying to give it the most driving purity it could cram in. The most traditional way for motorsport operations to do that has always been to rip out weight. And Porsche Motorsport didn't diverge from the plan. The 911's rear seats have been thrown out, along with a raft of other pieces Porsche Motorsport thought it could either do without completely, redesign to be lighter or stronger, or both. View 18 Photos The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. The pound-cutting starts at the body and bores all the way into the 911 R's chassis components, though there are some obvious nods to the marketing department that survived the dietician's axe. There is a lot of 911 GT3 in the body, with a combination of a carbon fiber (bonnet and front guards), a magnesium roof, polycarbonate front and side "glass," and aluminum everywhere else. The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. While the 911 R has lurid (and deletable) red or green racing stripes as standard, it's not supposed to be as wild looking as the GT3. Porsche replaced the GT3's adjustable, tall-standing rear spoiler with a more-subtle pop-up version, and the R uses a rear diffuser under the bumper to offset any loss of rear downforce. The rear seats are gone, and the two remaining seats use carbon fiber shells upholstered in tartan cloth (another nod to early 911s).

Remembering Porsche's illustrious Le Mans history

Not only does this weekend mark the running of the 82nd 24 Hours of Le Mans, it will also see the return of one of the race's most venerable brands to the top tiers of endurance racing. Porsche will campaign its first top-flight car since the 1998 911 GT1-98, the 919 Hybrid, at this weekend's race, in the hopes of knocking off its corporate rival, the dominant Audi team.
To understand just what a win for the 919 would mean, though, you need to look back on the intrinsic connection between the Circuit de la Sarthe and Porsche. It's a history that spans decades, dating back to the team's first win in 1970.
XCar has a great video on that history. At 25 minutes, it's a bit on the long side. Then again it is the Friday before Le Mans. Take a look below for the video.
