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:

2014 Porsche Panamera Turbo S is a 911 Turbo for the family man

In the event that the Porsche Panamera Turbo's 520 horsepower and 189-mile-per-hour top speed aren't enough to sate the appetite of the speed freak, Porsche has just given the auto show debut to the faster, more powerful Panamera Turbo S.
With 570 horsepower being pumped from a 4.8-liter, twin-turbocharged V8, the Panamera Turbo S promises even faster acceleration, hitting 60 mph in 3.6 seconds, a 0.3-second improvement over the standard Turbo. The top speed, meanwhile, climbs to 192 mph, which is kind of ridiculous for a car with four doors and a trunk.
Other enhancements that come with this Panamera's extra syllable include carbon-ceramic brakes and the entirety of Porsche's active chassis systems, including Porsche Dynamic Chassis Control and Porsche Active Suspension Management. The performance goodies come standard, but that doesn't mean the Panamera Turbo S is cheap.

Watch the Porsche 911 R rip through the mountains

A few days ago, the top-tier driver's Porsches, the 911 GT3 and GT3 RS, were the only game in town. Both are exclusively equipped with the technically excellent PDK, a dual-clutch gearbox virtually without equal. Of course, lots of folks, including Porsche die-hards, wanted to do it themselves, even if human shifts came at the expense of milliseconds of shift time. Porsche listened. You read all about the new 911 R two days ago when it was announced (if not, watch the video and then dive into the particulars at that link). It's an unabashed gift to that vocal minority. The folks that wanted a manual GT3 got one, and it's better than that. It's a throwback to the original 911 R, stripped of weight and unsightly aero bits like the massive rear wing of the GT3. There's even houndstooth-patterned cloth on the sport seats. It's a brilliant homage, without being overly retro. But how does it sound, and look in motion? See for yourself. We humbly suggest minding where the drool lands. Related Video: Porsche Coupe Performance Videos 911 porsche 911 r 911 r
