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 and Citro"en DS lovechild would look like this

The early Porsche 911 and the Citroën DS were two cars produced in the same era (though the DS launched in 1955, nearly 10 years before the 911), but they were vastly different from each other. The 911 was a uniquely German, pure-bred sports car, while the French-built DS had four doors and focused more on ride quality than sporting intentions. That made it all the more surprising when we came across the 911DS, a creation that binds the rear half of the Citroën to the front of an early, longhood 911.
The folks at Brandpowder are behind the creation, which we surmise was an exercise in design rather than an actual, completed project (some of the images look Photoshopped), but it's compelling nonetheless, with a turbocharged flat-six providing 260 horsepower. We hope someone builds it - though we're sure if that happened the early 911 crowd would cry afoul at one of its increasingly rare and valuable Porsches being grafted onto an old French car.
But as Brandpowder points out lightheartedly, perhaps the creation could transcend popular car culture: "The 911DS represents the effort of two countries, a genuine attempt to join their energy and talent into one thing. We hope Germany and France will be inspired by Brandpowder's story, as a metaphor for a better and greater Europe."

50th Anniversary Porsche 911 vs. Jaguar F-Type Coupe is a battle of beauty, brawn

There can't really be a loser between the Jaguar F-Type Coupe R and the Porsche 911 50th Anniversary Edition. One might be better than the other, but if you're behind the wheel of either of them, you can't complain. In a new video, Motor Trend takes on the difficult task of determining which one of these European powerhouses is the best, not just in terms of raw performance, but also how they actually feel to drive.
The Porsche 911 is one of the perennial favorites of the motoring world. It just doesn't go away and always seems capable of challenging the top vehicles in its class. In this video, Motor Trend takes a look at the 50th Anniversary Edition model that celebrates that heritage while boosting power somewhat over the standard version.
The F-Type Coupe is an incredibly masculine car, MT describing it as "a British Corvette." The coupe's exterior lines are tautly stretched over its athletic body, and it's supercharged 5.0-liter V8 sounds like a demon's growl. Jaguar seems to have things right with its latest sports car.
