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 Panamera gets new diesel in time for Frankfurt

Diesel may not be the first thing that comes to mind when you think of Porsche, but in the European market - that vital one which Porsche calls home - diesels are indispensable. Particularly when you're trying to extend beyond niche sports cars and into the mainstream luxury sedan market as Zuffenhausen has with the Panamera. In fact, diesels account for 15 percent of Panamera sales worldwide (even though they're not offered Stateside), so to keep oil-burning customers happy, Porsche has announced a series of upgrades.
Set to be unveiled in the flesh at the fast-approaching Frankfurt Motor Show, the new Panamera Diesel packs 300 horsepower. That's 50 hp (or 20 percent) more than the model it replaces, significantly dropping the 0-62 sprint from 6.8 seconds to 6 flat, and raising top speed from 152 miles per Autobahn-crunching hour to 161. While they were at it, Porsche's engineers also fitted the rear differential with torque vectoring (previously reserved for gasoline-burning models) and retuned the transmission and suspension.
You can delve into the press release below for all the details - including the new model's improved towing capacity! - but the reality, for better or worse, is that the Panamera Diesel isn't offered here. So if you've been celebrating Labor Day (or even Labour Day, for our friends to the north) like we have, don't go looking for it at your local dealer, who will have only a Cayenne Diesel to show you instead.

2014 Porsche Panamera S E-Hybrid

Porsche's Performance Plug-in Preamble
By the end of this year, Porsche will be producing as many plug-in vehicles (two) as mainstream automakers such as Toyota, Chevrolet and Honda. Before the 2015 918 Spyder hybrid supercar goes on sale in the US, though, it will be warming its customers up to the idea of a plug-in model with the 2014 Panamera S E-Hybrid. A step up from the previous Panamera S Hybrid, the new plug-in Panamera adds a more powerful and advanced electric drive system that pledges to deliver the performance expected of a Porsche with the added benefit of improved fuel economy and reduced emissions.
Going on sale in November, the Panamera S E-Hybrid is aimed at customers also considering the upcoming plug-in version Mercedes-Benz S-Class, but the car's dimensions and performance could make it a competitor for Tesla Model S customers. We headed to Germany at Porsche's invitation to see how well it performs, as well as check out the full range of newly refreshed Panamera models, which now numbers nine offerings - although we're still waiting for a production version of the gorgeous Sport Turismo wagon concept.
