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:

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

Audi's CEO might not have known of VW emissions scheme

There's been no shortage of finger-pointing when it comes to finding people to blame for the Volkswagen diesel-emissions scandal that broke last September. One rather powerful executive, however, appears to have escaped blame. That would be Audi CEO Rupert Stadler, whose company sold about 85,000 diesel vehicles with emissions-cheating software, Reuters says, citing people familiar with the process. US law firm Jones Day questioned executives at both VW and its Audi unit and has found no evidence that Stadler was complicit with the plan, which involved programming Volkswagen-made diesel engines to produce artificially low emissions when the vehicle was being smog-tested. In Audi's case, the engine type in question was the 3.0-liter V6 diesel. Officials with both VW and its Audi unit declined to comment, according to Reuters. That engine was used for the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year, in addition to the VW Touareg and Porsche Cayenne. Audi also sold the VW Group 2.0-liter four-cylinder in the A3 from 2010 to 2013 and 2015. VW has reached an agreement with US regulators concerning that engine, which is also not connected to Stadler. Last month, German newspaper Bild am Sonntag published specifics on how the 3.0-liter diesel cheated the emissions-testing process, including records that the motor was programmed to shut of its emissions-control equipment after 22 minutes of running, or about two minutes longer than typical emissions-compliance testing. Audi said last November that it would work on a software update for the V6's emissions-control system that would be submitted to both the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA), but the VW unit hasn't reached any settlement with US regulators implying that a solution was agreed upon. Volkswagen's settlement with the EPA will cost Europe's largest automaker as much as $15 billion in the form of buybacks, lease buyouts, vehicle repairs, and investments in zero-emissions technology. VW sold about a half-million vehicles in the US that contained the so-called "cheat" software.
