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.

Ferrari's Vettel sets lap record and take pole position for Chinese Grand Prix

SHANGHAI – Ferrari made Formula One rivals sit up and take notice after an ominous show of speed in qualifying for Sunday's Chinese Grand Prix. World championship leader Sebastian Vettel took pole position with a lap more than half a second faster than that of Valtteri Bottas, the fastest of the two Mercedes drivers in third place. The German's best time of one minute, 31.095 seconds – a Shanghai circuit record – turned up the heat on a chilly afternoon with Finnish team mate Kimi Raikkonen joining him on the front row. "We thought coming into today that we would be fighting for the pole position," said Bottas, whose reigning champion team mate Lewis Hamilton qualified fourth after aborting his final flying lap. "But it was definitely out of reach today, there was nothing in the lap that we could have gained that much." "I don't know if we can challenge, we're half a second behind today," added Hamilton. "We were quicker in the race in the last race (Bahrain) but they (Ferrari) were able to hold on. They will probably do the same tomorrow." Dominant isn't a word that has been used to describe Ferrari since they chalked up five straight drivers' titles and six consecutive constructors' crowns with Michael Schumacher, but they were imperious on Saturday. The front row lockout was their second in a row after Vettel beat Raikkonen to pole last weekend in Bahrain. "Ferrari were just way too quick," said Red Bull's Max Verstappen, who was fifth fastest but a hefty 0.701 seconds off Vettel's pace. "Somehow they've found a turbo button on the straight because they are really quick and still in the corners they are reasonably quick." Verstappen's Red Bull teammate Daniel Ricciardo added, "Ferrari has had really good pace all weekend and I can't say honestly now that we're going to have their pace tomorrow, but Mercedes definitely look within reach." Ferrari's speed had already stunned rivals after Friday's opening day of practice pointed to a close battle, even if Hamilton was top of the timesheets. With temperatures plunging on Saturday, the scarlet cars seemed to come into their own. Vettel, who holds a 17-point lead over Mercedes rival Lewis Hamilton after winning in Australia and Bahrain, is looking good for a hat-trick. No driver has ever won the season's first three races without being crowned champion that year, and the last Ferrari driver to do it was Schumacher in 2004 when he was at the peak of his powers and won the opening five.

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.
