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 Targa 4 GTS caters to a very specific customer [w/video]

Porsche is happy to cater to some very specific buyer demographics, and the brand's newly unveiled 911 Targa 4 GTS at the 2015 Detroit Auto Show is the perfect example of that tendency. The sports coupe is aimed at the customer who wants open-air driving without a full convertible, all-wheel drive traction and a little extra performance, all wrapped in a sporty package. Launching in the US in late-April, 2015, for $132,800, plus a $995 destination charge, this high-performance Targa benefits from all of the goodies from Porsche's GTS line. That gives it a 3.8-liter flat-six boasting 424 horsepower and 325 pound-feet of twist, and the choice of either a seven-speed PDK or seven-speed manual. The model also gets the Sport Chrono package, PASM, 20-inch wheels and a sport exhaust. Picking the PDK means the Targa 4 GTS can hit a top speed of 188 miles per hour and sprint to 60 mph in 4.1 seconds. Opting for the manual makes the run to 60 take a few more ticks at 4.5 seconds and scarcely cuts the top speed to 187 mph. The Targa 4 GTS is more than just about boosted performance, and shows off some handsome styling tweaks, as well. It wears a modded front bumper with an extra opening to cool the middle radiator. Plus, the wheels are 20-inch units from the 911 Turbo S, and the Bi-Xenon headlights get smoked coverings. Inside, drivers are held firmly in place by Sport Plus seats covered partially in black Alcantara. Porsche apparently sees a hole in its lineup that a higher-performance Targa can fill, and here it is. Look below for a video of intricate top doing its fascinating dance and read the German brand's full press release about the its latest take on the venerable 911.

The new 911 Targa 4 GTS More powerful, dynamic and exquisitely styled To mark the 50th anniversary of the 911 Targa, Porsche is offering this very popular model in the more powerful and dynamic GTS version for the first time. The targa concept of the 911 Targa 4 GTS delivers very safe driving enjoyment with all-wheel drive and a rollover protection bar; it also delivers open-air fun with a targa top that stows fully automatically. Contributing to a boost in dynamic performance are the 430 hp (316 kW) GTS engine together with the standard Sport Chrono package, PASM chassis, 20-inch wheels and a sport exhaust system.

Do we finally know which hybrid hypercar is fastest?

In order to properly compare and contrast the performance characteristics of competitive automobiles, a number of variables have to be sorted out. For instance, to diminish the human component, the same driver must be used for each lap, that driver has to be capable of wringing the maximum level of performance from each vehicle, and they should all be checked and prepared to make sure they are within manufacturer specs before hitting the track. Speaking of which, the conditions at the track – and, of course, it goes without saying that the cars have to be tested at the same location, on the same day – have to be as similar as possible. Naturally, arranging all of these variables is difficult, if not impossible, and that's especially true when the contenders are the Ferrari LaFerrari, McLaren P1, and Porsche 918 Spyder. As range-topping models from well-established performance players, these three hybrid hypercars are often lumped into the same category. But which one is fastest? Well, that's been a tough nut to crack, in part because the manufacturers themselves haven't always been willing to play along when it comes time to test these machines head-to-head-to-head. And so, with all that (probably unnecessary) preamble out of the way, we present to you the video above, in which this particular vehicular pedestal is toppled. All three cars are owned by a man named Paul Bailey, they were tested on the same day at the Silverstone circuit in England, and each had British Touring Car driver Mat Jackson at the helm. We're not going to spoil the results, other than to say that all three vehicles were incredibly fast and within spitting distance of one another at the finish line, as you would expect. Intriguingly, this video is said to be part one in a three-part series, so we have more Ferrari vs. McLaren vs. Porsche action to look forward to.
