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.

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.

Here are 12 electric pickups in the works

With the unveiling of the GMC Hummer EV, the list of planned electric pickups is expanding. Legacy automakers like Ford and Chevy have theirs coming, as do startups like Tesla, Rivian and Bollinger, as well as some lesser known brands. Here are all the electric pickup trucks we know to be in the works, along with a few that are being discussed or mulled over. GMC Hummer EV The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos We’ve seen it now, and itÂ’s the business. The GMC Hummer EV comes out swinging with 1,000 horsepower from GMÂ’s new Ultium electric powertrain program, a wealth of off-road features, a removable roof, Super Cruise and the revival of the Hummer name. WeÂ’ll see the first ones on the road next fall. Tesla Cybertruck Tesla Cybertruck at the Petersen Museum View 14 Photos Tesla revealed the Cybertruck last year with, ahem, unique styling, a number of powertrain options and a claimed range of up to 500 miles. It has a compressed paper dash, a ramp for the bed, and “shatterproof” windows. It has already racked up hundreds of thousands of reservations. It will be built in Texas. Rivian R1T 2021 Rivian R1T View 15 Photos EV startup Rivian revealed its R1T electric pickup toward the end of 2018 with a claimed 0-60 time of 3 seconds and a towing capability of 11,000 pounds. Preproduction began in September 2020 at RivianÂ’s factory in Normal, Illinois. Bollinger Motors B2 Bollinger Motors B2 side outdoors View 31 Photos BollingerÂ’s B2 electric pickup is a Class 3 off-roader with retro styling, removable roof panels, and a unique “frunkgate” with a pass-through down the center of the vehicle. It was created with both enthusiasts and workers in mind, with features that can get it to remote places (portal axles, hydro-pneumatic suspension) and to get things done (room for 40 2x4s, equipped with eight 110-volt outlets and one 220-volt outlet). Bollinger also plans to make the B2 Chassis Cab available for fleet customization. Ford F-150 Electric Electric Ford F-150 Towing View 9 Photos WeÂ’ve known this to be in the works since early 2019. Since then, details have trickled out. Back in June, Ford announced its F-150 Electric would be coming within two years. WeÂ’ve seen it pull a million pounds worth of train and trucks, heard it will have more power than any other F-150, and seen its LED-laden front end.
