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.

F1 cancels season-opening Australian Grand Prix over coronavirus

Workers pack up in pit lane after the cancellation of the Australian Formula One Grand Prix in Melbourne, Friday. / AP   MELBOURNE, Australia — As thousands of fans queued to get into the Australian Grand Prix, seemingly unperturbed by the coronavirus pandemic, the Formula One teams and drivers were packing up to leave. The rapid spread of the virus left organizers with little choice Friday but to cancel the season-opening race, particularly after McLaren withdrew because a team member tested positive for the COVID-19 illness and following heavy criticism from six-time world champion Lewis Hamilton. The two practice sessions that usually showcase what the teams have been improving in the off-season were less than two hours from starting when the decision was publicly announced. Principals of nine F1 teams and organizers met overnight and “concluded with a majority view of the teams that the race should not go ahead," a joint statement by FIA, motorsport's governing body, local organizers and F1 said. “It's been a very fluid situation," F1 chairman Chase Carey said. “We're all disappointed not to have it, but I think we've made the decision we had to make." “It's not like it came out of the blue," Carey told a news conference beside the F1 paddock that ended in light rain. “A week ago, when teams started traveling here, we felt it was the right decision (to stage the race). Clearly the situation changed in the interim." Practice, qualifying and Sunday's race were all scrapped, casting doubt over the Bahrain Grand Prix which is scheduled to be held next week and the Vietnamese GP, scheduled for April 5. Authorities in Bahrain have already said no fans will be allowed into the circuit. Carey said a decision on whether or not to go ahead with the the race would be made in coming days. The Chinese GP has already been postponed from April. Hamilton used the first official news conference with F1 drivers in Melbourne to say he was shocked that organizers planned to proceed with the Australian Grand Prix, which regularly attracts more than 300,000 people over four days. McLaren's decision to withdraw was ultimately the catalyst for the cancellation. That person and 14 other McLaren team members have been placed in quarantine in a Melbourne hotel for 14 days. Hamilton's Mercedes-AMG Petronas team said it sent a letter to the FIA and F1 requesting the cancellation and had commenced preparations to leave before the decision was publicly announced.

2015 Monaco F1 Grand Prix race recap [spoilers]

Lewis Hamilton came to Monaco with a new three-year deal with Mercedes-AMG Petronas and a vow to not let anything, including any "mistakes" by teammate Nico Rosberg, stand in the way of his best qualifying effort. Mercedes reportedly made it rain with a 100-million-pound deal, and Hamilton made it rain right back with his first pole position at Monaco. Rosberg did make a mistake but this time it was behind Hamilton, which meant he stuffed-up the qualifying attempts of rival drivers like Sebastian Vettel. So Rosberg starts second, 0.342 behind Hamilton but 0.449 ahead of Vettel in the Ferrari. Daniel Ricciardo thinks he should have been third, but a communication error with his engineers left him in the wrong engine setting for his final hot lap, so by the very first corner he'd lost the time he would have needed to get higher than fourth on the grid. The second Infiniti Red Bull Racing of Daniil Kvyat slots in behind him, ahead of the second Ferrari of Kimi "Not A Very Happy Day" Raikkonen, who just can't get it going lately. Sergio Perez did for the Sahara Force India what the car can't do on its own, which is grab a top-ten qualifying spot. Toro Rosso rookie Carlos Sainz had qualified eighth but missed a call to the weigh bridge, so he's been slapped into the pit lane. Pastor Maldonado in the Lotus inherits his eighth place, ahead of rookie Max Verstappen in the second Toro Rosso, and Jenson Button in the McLaren. Button only got up there because of two penalties: for Sainz, and Romain Grosjean who had qualified 11th but took a penalty for a gearbox change. Want to know how hard it is to do better on race day than in qualifying at Monaco? Even the never-say-die Fernando Alonso said, "Monte Carlo is a train of cars on Sunday, the race finishes on Saturday afternoon." Well obviously, he didn't take Max Verstappen's seek-and-destroy tactics into account. The young Dutchman had made passing look like a real option in Monaco, getting past Maldonado at St. Devote on Lap 7 after a bit of argy-bargy on Lap 6, then taking advantage of blue flags to slink past teammate Carlos Sainz and Williams driver Valtteri Bottas while hiding in Sebastian Vettel's slipstream. He tried the same move on Romain Grosjean on Lap 65, but Grosjean locked him out. Verstappen lined up the Lotus driver over the following laps, then looked like he slipped to the inside at St.
