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:

Next Audi A8 to drive itself up to 37 mph

Audi has been publicly, loudly, working the autonomous angle for years - it was working on Shelley, the autonomous TTS that would climb Pikes Peak in 27 minutes, way back in in 2009. Parent company Volkswagen had been working with Stanford University on autonomous vehicles for five years before that, and the same program collaboration would take the lead in Audi's efforts here. Where are we now? Well, a convoy of Audi A7s just drove journalists from San Francisco to the Consumer Electronics Show in Las Vegas, with "piloted driving in 100 mile stints." On the highway, the "piloted driving" A7 works up to 70 miles per hour and can change lanes, pass other cars, accelerate and brake on its own. A report in Autoweek says public adoption of the technology will continue with the next-generation A8, which will be able to navigate on its own up to 37 mph, make its way through traffic, find a parking spot and park itself. Over time, capabilities will be added - like a higher mph limit - as the technology and the legal issues are fine tuned. The A7 that just did the SF-to-LV run doesn't work in cities, only on highways, so it appears Audi is kicking this off with the abilities demonstrated in an A6 Avant last year at CES. That car had a Traffic Jam mode that only worked in dense traffic and up to 40 mph, but when in operation, it allowed the driver to watch a movie or conduct a videoconference. We have a feeling those two bits of icing won't be included in the fourth-generation A8, though. We'll be late to the party when the big sedan comes; Audi says it will go on sale by the end of 2016, but the US isn't expected to get it until 2017 as a 2018 model.

Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.
