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:

VW won't let emissions scandal keep it from racing

The Volkswagen Group may have its hands full dealing with the diesel emissions scandal. But that doesn't mean it will be curbing its considerable racing programs. At least not in any significant way. This according to Matthias Muller, who recently moved up from his previous position as Porsche CEO to preside over the entire group. Speaking with Autosport at the World Endurance Championship finale in Bahrain this past weekend, Muller emphasized the importance of racing to the company. "The motorsports programs are not in danger of being dropped or significantly reduced because motorsports is very important for the group and the brands," said Muller. "Basically we do not question our motorsport efforts." Of all the brands under the group's umbrella, several have prominent, top-level factory works racing programs, and others support customer racing teams. The Volkswagen brand has emerged as the dominant force in the World Rally Championship, securing both titles over the past three years. Both Porsche and Audi compete in the top tier at Le Mans and in the World Endurance Championship, trading places in the winner's circle. Audi also competes in DTM, and alongside Lamborghini, Bentley, and Porsche, and also offers GT3 and GTE racing cars to private customers. Lamborghini, Porsche, Audi, and Seat (once the leader in touring cars) all run their own spec racing series as well. Skoda continues to compete in lower-level rallying, leaving only Bugatti to draw on its prominent pre-war grand prix racing history. To hear Muller tell it, those racing programs – or at least the top-levels ones among them – aren't going away anytime soon. But there may still be some tweaks here and there, and we shouldn't expect any new programs to be launched in the near future. Porsche, for example, is anticipated to wind down its factory involvement in GT racing, after winning both the drivers' and manufacturers' titles in the WEC GTE Pro class this year in addition to its LMP1 victories. Instead it will focus on preparing new racing versions of the 911 for client racing teams. The auto giant was also reportedly close to branching out into Formula One in partnership with Red Bull. But after negotiations were interrupted by emergence of the diesel emissions scandal, that deal fell apart. It remains unknown which brand might have been represented in the F1 engine-supply program.

The 2014 Porsche Cayenne Turbo S brings 50 extra ponies to Detroit

Porsche has announced a new version of its popular SUV today at the Detroit Auto Show: the 550-horsepower 2014 Cayenne Turbo S.
This newly minted "flagship" of the Cayenne lineup is powered by a twin-turbocharged 4.8-liter V8 engine, and offers 50 hp more than the Cayenne Turbo. Performance figures are impressive for the sleek utility vehicle: 0-60 miles per hour can be dashed off in 4.3 seconds, while maximum speed is rated at 175 mph. The Turbo S also gets dynamic chassis control, torque vectoring and Porsche's Sport Chrono package - all standard equipment.
Visually the Cayenne Turbo S differentiates itself from the lesser models in pretty subtle ways. Gloss black trim decorates the gawping front air intakes, as well as rear-view mirror trim panel. The SUV also wears 21-inch Turbo II wheels, a la the 911 Turbo.
