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.

Here's today's round of auto plant closures in response to coronavirus

More automakers have shuttered factories, as businesses everywhere work to slow the spread of the Covid-19 coronavirus — and as the pandemic slows sales and disrupts parts supply chains. On Friday, the following closures were announced: • Volvo will close its factories in Sweden and the United States from March 26 to April 14. Volvo's U.S. facility, in Charleston, South Carolina, makes the S60 sedan. Its assembly plant in Torslanda, Sweden, turns out the XC90, SC60, and V90. Other Swedish facilities make engines and component parts. A Volvo factory in Ghent, Belgium, that builds the XC40 and V60 closed earlier this week and is expected to remain offline until April 6. Volvo's four factories in China have been reopened after a shutdown earlier this year. • Jaguar Land Rover announced that it will suspend production at its assembly plants in the UK over the coming week. The shutdown is expected to last until April 20. Elsewhere, production continues at the company's factories in India and Brazil, and JLR's joint-venture plant in China reopened at the end of February. • Bentley is closing its factory in Crewe, England, for four weeks, effective today. • Bugatti has put its atelier in Molsheim, France, on hiatus. No date was given for when assembly of its supercars might resume. • Mercedes-Benz on Monday will shut down its SUV factory in Alabama and its van assembly plant in South Carolina. Both will remain closed for a minimum of two weeks. Tesla yesterday revealed that it will suspend operations at its Fremont, California, vehicle assembly plant next week, on order from local officials there. Yesterday's factory closure announcements also included the U.S. assembly plants for Toyota (until April 6), Volkswagen (through March 29), Subaru (through March 29), and Hyundai (no time period specified). They join GM, Ford, Chrysler, Honda, Nissan, and Harley-Davidson, which earlier this week announced the suspension of production at their facilities.

2015 Australian Grand Prix all about grooves and trenches [spoilers]

We can't remember the last time 90 percent of the action in Formula One had nothing to do with cars setting timed laps. Yet that's was the situation at the Australian Grand Prix, continuing the antics from a scarcely believable off-season with blow-ups, driver and team absences, a lawsuit, and a clear need for some teams to get down and give us 50 pit stops. Nothing much has changed from a regulation standpoint, and at the front of the field nothing has changed at all. Lewis Hamilton in the Mercedes-AMG Petronas claimed the first position on the grid like someone put a sign on it that read, "Reserved for Mr. Hamilton;" teammate Nico Rosberg was 0.6 behind in second, Felipe Massa in the Williams was 1.4 seconds back in third. Sebastian Vettel proved that Ferrari didn't do another Groundhog Day routine this off-season, slotting into fourth. His teammate Kimi Raikkonen was not even four-hundredths of a second behind, ahead of Valtteri Bottas in the second Williams, Daniel Ricciardo in the first Infiniti Red Bull Racing, and rookie Carlos Sainz, Jr. in the first Toro Rosso. Lotus, now powered by Mercedes, got both cars into the top ten with Romain Grosjean in ninth, Pastor Maldonado in the final spot. However, even though the regulations are almost all carryover, in actual fact, everything has changed this year. Mercedes is even faster. Renault is even worse. Ferrari and Lotus are a lot better. Toro Rosso is looking like anything but a junior team. And McLaren is – well, let's not even get into that yet. Furthermore, this weekend was shambles: 15 cars started the race, the smallest naturally-occurring grid since 1963. Manor couldn't get its cars ready before qualifying. Bottas had to pull out after qualifying when he tore a disc in his back and couldn't pass the medical clearance tests. The gearbox in Daniil Kvyat's Red Bull gave out on the lap from the pit to the grid, and to give misery some company, the Honda in Kevin Magnussen's McLaren blew up on the same lap. When the lights went out, Hamilton ran away and was more than a second ahead of his teammate at the end of Lap 1. The advantage disappeared, though, because behind him, at the first corner, we got our first pile-up. As Raikkonen drove around the outside of Vettel at the right-hand Turn 1 it looked like Vettel, going over the kerbing, hopped to his left and bounced into Raikkonen.
