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:

TRANSLOGIC 148: Audi A3 Sportback E-Tron

We get an early drive of Audi's first plug-in vehicle for the U.S. market, the A3 Sportback E-Tron PHEV. Part of Audi's all-new A3 lineup, the Sportback E-Tron boasts an estimated electric driving range of about 30 miles at speeds up to 80 miles per hour. Find out what the future holds for Audi and their E-Tron vehicles.

Audi TT offroad concept wirelessly charges E-Tron quattro powertrain

Audi has been diving deep into the concept ideas pool for a while now, with out-there auto-show-only vehicles like the off-road Nanuk Quattro Concept (last year's Frankfurt Show) and the TT-previewing Allroad Shooting Brake (Detroit earlier this year). The automaker has also been hinting at wireless charging through its work with WiTricitiry and the Urban Concept Sportback from Frankfurt 2011. The latest evolution of these ideas is the brand-new Audi TT offroad concept show car, which makes an appearance at the Beijing Motor Show this weekend after being teased earlier this month. Putting wireless charging into an off-road body makes little sense at first glance - after all, if you're heading out into the wild, you'll be lucky enough to find a standard outlet - finding an in-ground induction pad will be near-impossible. Thankfully, we don't need to worry ourselves with this sort of logical conflict, since this is once again an auto show study. The powertrain is capable of 408 hp and 479.2 lb-ft of torque as well 123 MPGe. And that means interesting powertrain details, like a plug-in hybrid E-Tron quattro powertrain that uses two electric motors (one rated at 40 kW for the front axle, the other at 85 kW for the rear) and can even dispense with the plug part thanks to Audi Wireless Charging technology. The powertrain is capable of a total system output of 408 horsepower and 479.2 pound-feet of torque as well as a provisional fuel efficiency of over 123 miles per gallon equivalent. All with the ability to hit 100 kilometers per hour (62 miles per hour) in 5.2 seconds and a top speed of 155 mph. All-electric range is pegged at 31 miles thanks to a 12-kWH lithium-ion battery. More details than you can shake a stick at are available below. Audi says the TT offroad concept, which blends both coupe and compact SUV, could be a preview of "a new model in a future TT family," so if you've been hoping for another entry in the growing crossover coupe segment, tell Audi you'd like to see this in the real world some day.
