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 board members facing another ˆ1.8B lawsuit over VW takeover bid

Back in 2008, Porsche got the bright idea that it could take over Volkswagen in the midst of the worst economic slump since the Great Depression. Ignoring that this was a catastrophic move for the Stuttgart sports car manufacturer that that eventually resulted in it nearly going bankrupt and eventually being taken over by the same company it sought to control, the aftermath has left Porsche Chairman Wolfgang Porsche and board member Ferdinand Piëch in the crosshairs of seven hedge funds that lost out during the takeover and are now seeking €1.8 billion - $2.43 billion US - in damages from the two execs, according to the BBC.
See, investors bet on Volkswagen's share price going down, partially because Porsche said it wasn't going to attempt a takeover. But Porsche was attempting to take over VW, having bought up nearly 75-percent of VW's publicly traded shares. When word broke that Porsche owned nearly three-quarters of VW (which indicated an imminent takeover attempt), rather than go down like the hedge funds bet it would, VW's share price skyrocketed to over 1,000 euros per share, according to Reuters.
Naturally, when you bet that a company's share price is going to drop and it in turn (temporarily) becomes the world's most valuable company, you lose a lot of money, unless you're able to buy up shares before prices jump too much. This led to a squeeze on the stock, which the hedge funds accuse Porsche and Piëch (who are both members of the Porsche family and supervisory board) of organizing.

Mercedes-AMG GT vs. Porsche 911 [w/poll]

Mercedes-Benz designed the AMG GT to compete head-on with the Porsche 911. It's a clear, singular purpose, and Benz brings a lot of money, technology and race-bred expertise to the fight.
The AMG GT is Merc's followup to the awesome SLS AMG, the retro-modern, gullwing-doored coupe that took us by storm half a decade ago. But this new GT coupe is a more focused sports car than the SLS, rather than an all out supercar capable of extreme performance. It's got a brand-new V8 engine, and state-of-the-art technology that help it to not only be a proper Mercedes, but to be a serious performer.
Mercedes will sell its new baby in two models. The GT S arrives first, in spring 2015, followed by the standard GT in mid-2016. Of course, there's room to grow from there. And while Porsche may have already expanded its 911 range to include a vast variety of models, here's how Stuttgart's icon stacks up against Affalterbach's bad boy.
