Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.

VW CFO Hans Dieter Potsch nominated as new board chairman

The search for a successor to Ferdinand Piech has come to an end as the Volkswagen Group has nominated a new chairman. The Executive and Nomination committees of VW's Supervisory Board have put their weight behind one Hans Dieter Potsch, who currently serves on the company's management board as its chief financial officer. He's expected to continue in his current role until November when an extraordinary general meeting of the supervisory board can be called to confirm his nomination and a replacement CFO can be found to take his place. As you may recall, the chairmanship of the Volkswagen board fell until recently to Ferdinand Piech, grandson of Ferdinand Porsche and one of the principals of the Porsche family that holds over 50 percent ownership in Volkswagen through Porsche Automobil Holding SE. Piech went head to head with VW CEO Martin Winterkorn and ultimately lost. Piech resigned and Winterkorn is about to have his term as chief executive extended through the end of 2018. In Piech's place, former union head Berthold Huber was named as interim chairman, but is now referred to in the statement below once again as deputy chairman instead. An Austrian native, Potsch is an industrial engineer by training. He started his career at BMW where he ultimately served as group controller, and subsequently served as CFO and as chairman at a number of German corporations. Potsch joined the VW management board in 2003, initially without portfolio, and soon assumed the financial portfolio – a role he has held until now. In 2009 he took on the additional role of chief financial officer at the Porsche holding company, whose supervisory board representatives are the parties proposing Potsch's nomination as the group's new chairman – even though he is not, strictly speaking, one of their own. In a related development, it appears that Julia Kuhn-Piech will be leaving her board seat sooner than expected. The departing chairman Ferdinand Piech opposed his niece's nomination to the board in his place, and now she'll apparently be stepping down to make way for the family's new choice of chairman.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
