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 GT2 test mule caught in the snow

This may look like a weird, cobbled-together Porsche, but insiders tell us we're actually looking at the forthcoming GT2. Maybe even a GT2 RS. Those schooled in the intricacies of Zuffenhausen nomenclature will be suitably excited by now. But for the rest of us, the GT2 (with or without the RS) represents the pinnacle of the most hardcore 911s. It's essentially a 911 Turbo without the all-wheel drive but some other goodies thrown in – or to put it another way, it is to the Turbo what the GT3 is to the 911 Carrera. Porsche first did a 911 GT2 back in 1993 based on the 993-generation model. It then did another based on the 996, and then on the 997. But the last one we saw was the GT2 RS that came out in 2010, packing 612 horsepower channeled exclusively to the rear wheels through a six-speed manual transmission. The German automaker didn't do a GT2 version of the 991, but now that the entire model line is undergoing a transformation – and an near-complete switch to turbo power – it apparently has another one in store for us. Aside from ditching the Turbo's all-wheel drive, the new GT2 will be lighter and pack more power – as much as 700 hp, from what we hear. As you can see from the spy shots, the test mule spotted romping in the snow is also wearing larger exhaust tips and the signature GT2 RS black hood. Expect the finished product to wear its own shoes and a more extreme aero kit as well. The question on everyone's minds will be whether it will, like the latest GT3 and GT3 RS, be offered only with a dual-clutch transmission, a conventional manual, or the buyer's choice of either. We'll find out sooner or later as the most extreme of Elfens is tipped to surface late next year. Related Video:
