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-Piech buy 10% stake in VW's holding company

In August, 2009, as the scuttled merger of Porsche and Volkswagen had gone bad and Porsche was backed up against the ropes, Porsche Automobil Holding SE (PAHSE) relinquished a ten-percent stake in itself to Qatar Holdings as well as options it held on 17 percent of VW shares. The sale meant that, for the first time since the founding of the company 61 years before, an entity outside the Porsche and Piech families had a say in the running of PAHSE.
Buying that ten-percent stake back returns full ownership to the two families, the holding company's sole possession being ownership of 50.7 percent of VW's common shares. The price paid wasn't disclosed, but at market rates the purchase would be worth close to $1.25 billion. Qatar intends to hold onto the 17-percent stake it has in Volkswagen.

Porsche kicks off Macan production at revamped Leipzig plant

After over two years of construction and roughly 500 million euros ($684 million at current rates) invested, Porsche finally opened its Leipzig, Germany, factory expansion on February 11. The improvements to the plant are dedicated to building the Macan and include a new body shop, paint shop and assembly line that are advancing Porsche's goal to sell 50,000 Macan's per year. The company believes that the new model is going to push it to over 200,000 annual sales 3 years ahead of schedule, and the enlarged branch can support even more Macan production, if there is demand.
"We are totally convinced in the qualities of this location and that the Macan will be a marketing success," said Porsche Chairman Matthias Müller during the opening celebration. The company opened its Leipzig factory in 2002 to build the Cayenne and added Panamera production in 2009.
The Macan models are due to launch in the US this summer with prices starting at $49,900. Scroll down to learn all of the details about the Macan's Leipzig assembly plant.
