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:

Mystery shoppers love Infiniti, hate Tesla

Infiniti, followed by Lexus tied with Mercedes-Benz took the top two spots for best sales experience according to mystery shoppers from the latest Pied Piper Prospect Satisfaction Index, while EV manufacturer Tesla recorded the lowest overall score. Not surprisingly, premium brands dominated the top ranks. Including the three already mentioned, luxury brands occupied seven of the top ten spots and included Audi, BMW, Porsche, and the only American brand to crack the upper echelon, Cadillac. Toyota, Volkswagen, and Nissan rounded out the first ten positions. The news for domestic automakers isn't good. Aside from Caddy, the only other star-spangled automaker to score above the industry average is Chrysler. The rest of FCA, most of GM, and all of Ford fell below the line. But Pied Piper's mystery shoppers handed Tesla the biggest walloping – the company is ten full points below the next lowest brand, Volvo, and its score of 86 is 17 below the average of 103. It's baffling, considering the company's touted direct-sales model. "Tesla leaves me scratching my head," Fred O'Hagan, Pied Piper's president and CEO, told Wards Auto. "They own all of their stores, so you would think each one would be doing the same thing. But they're not. Tesla is consistent in its inconsistencies." O'Hagan added that there's a "huge variation" in Tesla's store-to-store effectiveness, and that in some cases, shoppers found showroom workers that acted more like "museum curators," Wards Auto reports. It might be popular to call Tesla the Apple of the car world, but based on Pied Piper's work, the brand has a long way to go to emulate the uniform shopping experience of an Apple Store. The news might be bad for Tesla, but even for the brands that scored below average, there's cause for celebration. Only Tesla and Mini lost points in this year's rankings, and only Mercedes and Lincoln held steady. Every other brand, including Infiniti, which topped the index for the first time, gained at least one point. The biggest improvements belong to Porsche, Land Rover, and Mitsubishi, which all jumped five points. Pied Piper's annual Prospect Satisfaction Index uses mystery shoppers – over 6,100 this year – from across the country to assess dealers and generate rankings from over 50 individual factors.

Audi takes cars that park themselves to a whole new level

Autonomous cars are impressive displays of in-car technology, but what exactly would the benefit of such systems be for the average driver? Audi has answered that question by showing off its Piloted Parking system for the Audi Connect at CES 2013.
Installed on this Audi A7, Piloted Parking allows a driver to drop themselves off and have the car autonomously drive away on its own and find its own parking spot. The car can then later be retrieved by "calling" it back with a specially designed smartphone app. We'd be lying if we said this didn't bring back memories of Michael Knight summoning KITT with his wristwatch. The most impressive part of this car might be the fact that the car is fully autonomous but doesn't have any obvious sensors or monitors on the exterior of the car like many other self-driving cars have.
Check out a video of the this innovative technology in action after the jump.
