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.

Wingsuits are somehow involved in new season of 'Top Gear'

It's a shame that Matt LeBlanc is leaving "Top Gear," but there's a bit of solace in the situation: There's still one more season of him as frontman. BBC just released the new trailer for series 26, and it shows LeBlanc, Chris Harris and Rory Reid getting into all sorts of shenanigans around the globe. "Top Gear" announced LeBlanc's imminent departure back in May 2018, but he still had to finish one more season before leaving. Thus, the upcoming series will be his last, and it looks like he'll go out in a whirlwind of dust, bent metal, water spray and burnt rubber. The trailer shows everything expected from a season of the storied automotive show (well, everything except Hammond, May, and Clarkson, if you're one of those people). There will be precision driving, dubious stunts, name-calling and gobs of stunning videography. In the short one-minute clip, there are flashes of numerous attention-piquing vehicles. The new Bentley Continental GT, a Bentley Le Mans racer, Porsches, Ferraris, the Aston Martin Vantage, and the Mercedes-AMG GT all make appearances. And for some random fun, the boys are seen in wingsuits (doubtful it's actually them), and playing polo in some three-wheel rickshaws (before wrecking said rickshaws). We'll update with more information as soon as we know when the show will start.

Leno shows off his current project cars

When your car collection grows to the enormous size of Jay Leno's, adding the usual muscle cars or European exotics loses the allure. It becomes necessary to start taking the things in weird directions. Leno is proving just that with his latest tour of many of the ongoing projects currently happening in the garage. With everything from Harley-Davidson generators to '50s hot rods on display just in this short video, there's something any fan can love. The place is like an automotive wonderland. For most people any one of these projects would be an absolute dream. For example, Leno has a copy of a one-off Mercedes-Benz racecar transporter that is nearly ready to drive. Another project hasn't even started yet but already seriously piqued our interest. Leno obtained a very ratty 1966 Volvo 122S wagon, but rather than just a restoration he's has a plan to get a V8 with a flat-plane crank from Volvo performance specialists Polestar. Another project on the way should provide a significant upgrade in performance, while still being quite green. Leno's team has already rebuilt the frame and wooden body from a 1914 Detroit Electric, and with that work done they've started dreaming of a modern drivetrain for it. One proposed candidate for the swap has been to install motor from a Nissan Leaf and a bank of lithium-ion batteries.
