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:

eGarage video features Helmuth Bott's personal Porsche 959 prototype

"We thought we were going to build a super-911," said Peter Schutz, former CEO of Porsche AG of the development of the Porsche 959. That was before it started getting expensive. At that point, Helmuth Bott, Porsche R&D director got frightened. Costs ballooned because of the all-wheel drive, sequential turbocharging and other technology Porsche had never even thought about when it set out to build a 911 to compete in Group B. Schutz continued, "The amount of resources we were committing got totally out of hand." Instead of pulling the plug, Bott doubled down and drew on the strength of his brilliant team to build a car whose impact is still echoing aross the industry.
"It's probably one of our most prized possessions" says Don Leatherwood, Director of the Brumos collection where Dr. Bott's personal prototype resides, and where Frazer Spowart went to see the car and create a video for eGarage. Check out the sights and sounds of the 959 before it was the 959, and get personal takes on the car from Hurley Haywood, Peter Schutz and Don Leatherwood. Keep reading to see the video.

Will the Mission E be the world's first must-have EV?

The Porsche Mission E concept was recently green-lit for production and has a tentative production date just before the end of the decade. With the recent onslaught of all-electric technology, the question remains: Which automaker will release the first must have all-electric EV? Tesla has clearly gained experience in testing the worldwide appetite for luxury, six-figure EVs, having sold its 100,000th vehicle in just three years and six months. But it remains to be seen if automakers can truly manufacture the ultimate green driving machine. Audi has shown its R8 e-tron but acknowledged that it will be produced in only limited quantities. On the other end of the spectrum, vehicles like the Chevy Bolt and BMW i8 are being produced for mass consumption, but will they satisfy the enthusiast who is looking for more than a commuter car? Tesla's Model S has certainly raised eyebrows and collected accolades with "ludicrous" level straight-line performance, but how well will the vehicle stand up to long-term ownership for enthusiasts? Porsche has dismissed any notions of autonomous driving in its vehicles, suggesting that it will try to stay close to its high-performance roots. This would seem to suggest that despite all the forecasted performance cred of the Mission E – 582 horsepower, 0–60 in 3.5 seconds, and a 310-mile range – potential buyers may not be getting the latest and greatest in gee-whiz-bang autonomous technology. And while Porsche has offered that future iterations of its 911 and 718 may in fact use hybrid-assisted drivetrains, the execution of a true, mass-produced, all-electric sports sedan remains to be seen. One thing is for certain, unlike start-ups like Tesla, the larger, more established manufacturers have larger budgets and more time to invest in R&D. Consumers have raised expectations from the more mature automakers in terms of reliability and the overall finish of their products. The arrival of the Mission E production car may introduce us to electric sports sedans that emphasize performance over efficiency while still eliminating its carbon footprint.
