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.

Race recap: 2016 Bahrain Grand Prix was everything good and bad about F1

Nothing was as it seemed heading into Bahrain. We were told team bosses had nixed the qualifying experiment that flunked every test by every measure in Australia, but that didn't happen. The FIA didn't give the teams the option of a wholesale return to the old format, the governing body only held a vote on whether to revert back to the old format in Q3 but stick with elimination gimmicks in Q1 and Q2. McLaren and Red Bull dissented, denying the chance for hybrid rounds. We're surprised none of the smaller teams voted against since elimination qualifying is hardest on them. Given the chance to fix the system again in Bahrain, Formula 1 failed again. The FIA and Bernie Ecclestone don't want to go back to the old system – because the race promoters don't want to go back to the old system – so all we know for sure is that there will be more meetings. We also thought Fernando Alonso would race in Bahrain after being given medical clearance, but a follow-up scan by the FIA showed fractured ribs and a damaged lung, ruling him out. And we thought Ferrari might have the pace to conquer Mercedes-AMG Petronas this year – and they might yet, but not on Saturday. That's why the Bahrain race began with another Mercedes one-two, Lewis Hamilton ahead of Nico Rosberg, Ferrari drivers Sebastian Vettel and Kimi Raikkonen behind. The Australian outback is plagued with rabbits, which must have something to do with how Daniel Ricciardo keeps pulling them out of his helmet; the Aussie got his Red Bull up to a surprising fifth on the grid. Williams drivers Valtteri Bottas in sixth and Felipe Massa in seventh would need to get him out of the way quickly to show what the car can do after an unsatisfying race in Australia. Nico Hulkenberg lined up in eighth for Sahara Force India. As proof the qualifying format failed again with its sophomore attempt, the last five minutes of Q2 were disappointing. Hulkenberg had the track completely to himself for his quali run, the only two cars on track after him were the Williams duo who weren't setting a time, but getting a set of soft tires ready to start the race on. As for Q1, the only reason for on-track action in the last three minutes was because Hamilton flubbed his first timed run. Romain Grosjean continued Haas F1's fruitful start to the season with ninth place, ahead of Max Verstappen in the Toro Rosso closing out the top ten. At the end of a long red light to start the race, Rosberg claimed his right to victory before Turn 1.
