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:

Steve McQueen's last Porsche headed for auction

Most people might be happy ordering a new car off a lot, but Steve McQueen was most definitely not "most people." The Hollywood icon was known to custom-order his cars. What you see here is the last car McQueen would ever order, and now it's going up for auction. This is a 1976 Porsche 911 Turbo Carrera (known to aficionados as the 930) that the actor had done up in Slate Gray, with sunroof, dual mirrors, a limited-slip differential, black sports seats, and a switch on the dashboard to kill the taillights in case he was being pursued at night. Chassis number 9306800408 is powered by a 3.0-liter flat six that's turbocharged but (in a rare early configuration) not intercooled. The air-cooled engine features Bosch K-Jetronic fuel injection and drives 234 horsepower through a four-speed to the rear wheels. McQueen ordered the 930 new from Bob Smith Porsche in Hollywood. He died a few years later, never having special-ordered another new car – making this the last of its kind. "This car is rich in history," said his son Chad McQueen. "This is the last of the McQueen cars, really. That's known. That's real." And it can be yours, if you place the right bid. Mecum Auctions has it on consignment for its upcoming event during Monterey Car Week, with a portion of the proceeds to benefit Boys Republic – McQueen's own alma mater. STEVE MCQUEEN'S LAST SPECIAL-ORDER PORSCHE TO BE OFFERED AT MECUM MONTEREY 1976 Porsche Turbo 930 Personalized by The King of Cool to Cross the Block Aug. 15 WALWORTH, Wis. – July 14, 2015 – The very last car special-ordered by The King of Cool—the late mega movie star Steve McQueen—will be offered for sale at the Mecum Daytime Auction in Monterey this Aug. 13-15 at the Hyatt Regency Monterey Hotel and Spa – Del Monte Golf Course. A portion of the proceeds from the sale of the 1976 Porsche 930 Turbo Carrera will be donated to McQueen's alma mater, the reform school Boys Republic. "This car is rich in history," says McQueen's son Chad. "This is the last of the McQueen cars, really. That's known. That's real." McQueen's untimely death in 1980 at age 50 made this 1976 Porsche 930, chassis 9306800408, the very last of his special-order cars. His insatiable and notorious need for speed and his affinity for fine automobiles meant always having the best sets of wheels, and his Porsche 930 is no exception.

Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.
