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:

VW uses NorCal Forest to make e-Golf carbon neutral

On the one hand, it's just a forest. There are beautiful redwood trees and clean air, cool, quiet creeks and hidden wildlife. You know, a forest. The kind that have existed for millions of years. On the other, it's a carefully managed collection of natural resources that lets companies pay money to make their products more beneficial to the environment. Welcome to the Garcia River Forest. For our purposes, the Garcia River Forest is interesting because of its connection to Volkswagen. Its young redwoods are helping Volkswagen create something almost unheard of in the automotive industry: a (mostly) carbon-neutral car. The 10,000-foot overview of how this works is as follows: when you buy the electric car, part of your money goes to support three carbon offset projects. These projects (the one in the Garcia River Forest, the Big River And Salmon Creek Forests in California, and the McKinney Landfill in Texas) have put a price on the value of not letting more carbon get into our atmosphere. The calculations come in the form of credits per metric ton of CO2 and VW has paid enough money to cover the emissions it generates during the production and distribution of the e-Golf as well as the charging for around 36,000 miles of driving. VW worked with 3Degrees, a provider of carbon offset services, to calculate the amount of greenhouse gas (GHG) emissions that each e-Golf will be responsible for, from the factory to the driveway. The Garcia River Forest location is managed by The Conservation Fund (TCF). VW originally announced the carbon-neutral program back when it revealed US details for the e-Golf, in August 2013. Stuart Gardner, project manager at VW of America for the Golf family, told AutoblogGreen that the idea for the carbon offset came from the way VW understands plug-in vehicle buyers. "At Volkswagen, we strive to be leaders in e-mobility and developing alternative powertrains and we realize that, when someone buys an electric vehicle - the e-Golf, for example - they are doing more than just buying an electric vehicle," he said. "They are buying a lifestyle and they want to engage in this lifestyle." VW is not releasing the specific amount of the purchase price of each e-Golf that is directed to the Garcia River Forest (or any other carbon offset projects).

Watch Chris Harris in the electric VW ID.R waste a McLaren 720S

The Volkswagen ID.R doesn't have much in common with a McLaren 720S, other than the fact that they are both performance-crazed cars. One gets its power from batteries, the other from gas. One uses electric motors, the other a twin-turbocharged 4.0-liter V8. One is a halo prototype vehicle, the other is a road-legal supercar available for purchase. So when Chris Harris and "Top Gear" decided to "race" the two against each other, it was more of a demonstration of the VW's unreal capabilities than any sort of real competitive faceoff. In episode five of Top Gear's 28th season, which just aired February 23, the trio of Harris, Freddie Flintoff and Paddy McGuinness welcomed Youtuber KSI on the show and ventured out on a luxury sports car road trip with an Aston Martin, Porsche, and Ferrari. Separately, Harris took to the track to test out Volkswagen's golden egg of the moment, the ID.R. As VW fully launches into its electric-vehicle push, the ID.R is meant to exhibit what battery-electric technology is capable of. With two electric motors, one on the front axle and one on the rear axle, the 2,425-pound ID.R has four-wheel drive and makes a claimed 670 horsepower. As Harris notes in the video, the ID.R. was not built for a specific regulation-bogged racing organization or competition, and thus, it's only held back by the rules of Mother Nature and Father Physics. Since the car's debut, it has been annihilating records around the world, including at Pike's Peak, Goodwood, the Nurburgring, and Heaven's Gate. Chris Harris didn't set any records in the ID.R., but he certainly showed how outrageous this machine is. The 710-horsepower 720S can go from zero mph to 62 mph in less than three seconds, and the ID.R has a sizable lead within that same time. Again, this wasn't an instance of test-and-conclude, it was a show of perspective. The ID.R is a race car, so even though the 720S is one of the best supercars in the world, it never stood a chance.
