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:

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.

Audi introduces Q7 E-Tron 2.0 TFSI in Shanghai

Audi made a name for itself with its Quattro all-wheel-drive system, and is rapidly expanding its range of E-Tron hybrids. And now it's bringing the two together for the first time with the new Q7 E-Tron 2.0 TFSI. The company's first vehicle to combine a turbocharged engine, hybrid assist and all-wheel drive, the Audi Q7 E-Tron 2.0 TFSI boasts all the enhancements wrought on Ingolstadt's new flagship crossover, but with a range of over 633 miles – nearly 33 of them on electric power alone. The powertrain pairs a 2.0-liter turbo four with an electric motor that combine to deliver 367 horsepower and 516 pound-feet of torque. That's said to be enough to send the hybrid luxury crossover to 62 in 5.9 seconds and on to a top speed in excess of 136 miles per hour, while boasting fuel efficiency of a claimed 94 miles per gallon. Unfortunately, however, the Q7 E-Tron is earmarked only for specific Asian markets – namely China, Singapore and Japan. So don't count on seeing this hybrid crossover in US showrooms any time soon – at least not in this specification. Ingolstadt, 2015-04-16 Great class, minimal emissions – the new Audi Q7 e-tron 2.0 TFSI quattro - First TFSI plug-in hybrid with quattro all-wheel drive - Best-in-class: up to 53 kilometers (32.9 mi) electric range - Maximum efficiency with hybrid management and heat pump - Available for Asian markets The Audi Q7 e-tron 2.0 TFSI quattro marks the first time that Audi has combined a TFSI plug-in hybrid with quattro all-wheel drive. Audi developed it specially for Asian markets (China, Singapore and Japan). It is sporty, comfortable and at the same time supremely efficient. It accelerates from 0 to 100 km/h (62.1 mph) in under six seconds while consuming just 2.5 liters of fuel per 100 kilometers (94.1 US mpg) according to the measurement method specified in China for plug-in hybrid vehicles (PHEV). Audi is presenting the Q7 e-tron 2.0 TFSI quattro at Auto Shanghai. According to the measurement method specified in China for PHEVs, the large SUV can cover up to 53 kilometers (32.9 mi) solely on the electricity stored in its lithium-ion battery – quietly, powerfully and with zero local emissions. Total range is 1,020 kilometers (633.8 mi). The Audi Q7 e-tron 2.0 TFSI quattro will be available beginning in 2016. Sporty power and minimum consumption The Audi Q7 e-tron 2.0 TFSI quattro has sporty power.
