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:

Watch Porsche's 918 Spyder break a sweat while hot weather testing

With five months left until the 2015 Porsche 918 Spyder enters production, Porsche engineers are still putting the hybrid sports coupe through a battery of last-minute tests. To give us new reasons to ogle over the car - as if we needed any more - Porsche has released a short video showing the 918 Spyder undergoing shakedown tests in the hot Nevada desert. And you can't drive through Nevada without visiting Vegas, too, right?
Although there's really nothing new to see in this video, it's still fun to watch as Porsche approaches one million test miles logged on this exciting new high-performance model. One interesting part (at around the 0:37 mark) shows the car taking off under electric power and then transitioning to engine power, which results in a mix of whirs and growls as the 918 Spyder switches from a 127-horsepower electric vehicle to an 887-hp hybrid supercar. Scroll down to watch - and hear - Porsche's latest creation in motion.

Seinfeld takes Seth Meyers out in the perfect Porsche

The latest episode of Comedians In Cars Getting Coffee features Seth Meyers of Saturday Night Live fame riding shotgun in what is a very special Porsche from host Jerry Seinfeld's collection: a 1973 911 Carrera RS 2.7. Seinfeld chose the "no-nonsense" sports car because he thought it fit his guest's personality (Meyers thinks motorcycles "are like the cigarette of transportation"), but we enjoy the chance to see one of these rare, über-valuable Porsches being driven on city streets - and in the rain, no less! What we don't like seeing is the Carrera RS being parallel parked behind a pick-up truck, though, fortunately, it seems that Seinfeld was able to avoid any front-end damage to the comparatively fragile Porsche.
Once at the coffee shop, the two comedians have a candid conversation about Meyers' time with SNL, from his early days on the show when he didn't think he was good enough to be a cast member to some of the high points in his career, such as SNL's "Really!?" segment that he performed in and how he became a writer for the show.
After coffee, when they're back in the car and Seinfeld opens up the throttle of the lightweight RS 2.7, he manages to eke out a big grin from Meyers - or maybe it was a grimace at the thought of driving in the rain on old tires. Whatever the case, be sure to watch the video below (and stay tuned until the end for a surprise).
