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:

Audi E-Tron Sportback Concept previews 2019 production model

Audi has revealed the E-Tron Sportback concept it has been teasing ahead of Auto Shanghai. The all-electric model, the automaker says, previews a production model slated for 2019. Audi will launch an electric SUV with a driving range of 311 miles in 2018. "Following close on its heels, in 2019," says Audi Chairman Rupert Stadler, "comes the production version of the Audi E-Tron Sportback – an emotional coupe version that is thrillingly identifiable as an electric car at the very first glance." The E-Tron Sportback is powered by three electric motors – one on the front axle, and two on the rear ­– providing a total 320 kW (429 horsepower), with a boost mode that ups that output to 370 kW (496 hp). It's capable of a 0-62 mile per hour sprint of 4.5 seconds. A liquid-cooled 95-kWh lithium-ion battery provides 311 miles of driving range (on the European cycle). The concept features Audi's singleframe grille, with an illuminated four-ring logo. The front of the car is shaped for optimal airflow, and the dip in the hood also gives it a uniquely sporty look. Its front fascia integrates lighting that not only illuminates the road, but can project animations or provide communicative signals to other drivers or pedestrians. Its 23-inch wheels are imposing, giving the car a muscular stance. Side mirrors are replaced by slender cameras, which improve airflow and provide a better view of the car's surroundings, helping to eliminate blind spots. By revealing the E-Tron Sportback concept in China, Audi is acknowledging the significance of the country's electric vehicle market. "There are already about 150,000 charging stations in the country, with another 100,000 due to come on stream by the end of 2017," notes Audi Board Member for Marketing and Sales, Dr. Dietmar Voggenreiter. "We are well equipped for this rapid growth. In the next five years we will be offering five E-Tron models in China, including purely battery-powered vehicles with ranges well in excess of 500 kilometers (310.7 miles) such as the Audi E-Tron Sportback."

Audi's fastest cars won't catch your drift

"I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." – Stephan Reil Drift modes are popping up in sports cars all over the world, but Audi Sport development boss Stephan Reil refuses to have anything to do with them, insisting they're a waste of time and tires. So if you want to show off with a wild-looking, tire-smoking, perfectly controlled drift in an Audi Sport model, you will have to brush up on your car control, not your button pushing. "No drift mode. Not in the R8, not in the RS3, not in the RS6, not in the RS4," Reil said. "I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." That seems a bit like Reil and his team are missing a trick that is proving popular with enthusiast buyers and isn't technically difficult to do. It's also a whole lot safer than holding down the skid-control button for long enough to switch off all the electronic safety nets, which Audi Sport will actually let you do. "You can do it yourself [drifting] with the ESP off, if you hold it [the button] for three seconds," Reil challenged. "Then it will not intervene for you even when it [the car] is fully out of control, because that's what you asked it not to do. "You wanted the full control by pushing that button. You got it." Almost every fast car, from Ford to Ferrari, now comes with (or soon will) a drift mode so drivers can just stomp on the gas and turn the wheel to instantly look like rally stars. The dangers of do-it-yourself drift control (which our forefathers used to call "driving") make up most of the moral defense for the companies that use the computer-controlled versions. While critics have called drift modes irresponsible, proponents argue that it is far safer than switching off all the safety nets, because there is still a level of skid-control safety behind it. "Drift control is a lot safer than just turning everything off," BMW M chief Franciscus van Meel said during the launch of the M550i xDrive. "The drivers can enjoy the car on a track but it still has another level of safety to catch them if they make a mistake."
