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:

Audi updates A3 with Virtual Cockpit, more goodies

Audi has announced a series of updates to the A3 family. And though we're still waiting for confirmation on its arrival here in North America following its introduction back in Europe next month, the revisions bode well for Ingolstadt's baby. Chief among the enhancements for the latest A3 is the inclusion, as promised, of the company's Virtual Cockpit infotainment system. One of our finalists for 2016 Tech of the Year, the Virtual Cockpit moves many of the controls and menus you'd expect to find in the center console display into the instrument cluster to make them easier for the driver to navigate (albeit at the expense of a co-pilot's assistance). Audi also used the occasion to install some of its latest driver assistance systems, including active lane assist, pedestrian protection, and available traffic jam assist that helps the vehicle crawl along in bumper-to-bumper conditions. The revised A3 also features new front and rear fascias, incorporating a sharper grille and new head- and taillights, with available Matrix LED units up front. Globally speaking, Audi is offering the updated model with six different engines – three gasoline and three diesel – including a 1.0-liter inline-three for the first time. There's the hybrid E-Tron model as well, and the flex-fuel G-Tron model that can run on natural gas. More enticing though is the new S3, which benefits from a ten-horsepower boost to produce a more substantial 310 hp and as much as 295 pound-feet of torque. With sedan, convertible, and three- and five-door hatchback bodystyles, that makes for a lot of combinations, though not all engines will be offered in all forms. Watch this space for word on US availability. In the meantime, you can scope out all the details on the various variants in the press release below and the high-resolution images in the exhaustive gallery above.

Audi, Jag, Kia and Tesla top Strategic Vision 2014 Total Quality Index

A couple weeks ago, J.D. Power released its latest Initial Quality Study, which gave high marks to Porsche, Hyundai and General Motors, with the latter earning more individual IQS awards than any other manufacturer. Now, it's Strategic Vision's turn, and it's doling out its praise not to Porsche, but to Tesla, which wasn't even included in the JD Power IQS.
The Model S was named the best vehicle overall in total quality, while Porsche's corporate brother and endurance-racing rival, Audi, was named the best premium brand, alongside Jaguar. Strategic Vision cited the Q5 and the ancient Q7 for individual segment awards, as well as the A5, which was a mere point off the top of its segment. SV also handed out compliments for the Audi's interior work. The win for the German brand is a nice improvement over its IQS score, with which it landed above the industry average, but solidly mid-pack.
Jaguar was without a segment winner, although SV did say that the Indian-owned English brand had a number of vehicles very near the top of their segments. This is the second significant win for Jag in two weeks, after it finished second overall on the JD Power IQS a few weeks ago.
