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.

Mercedes considering Audi Allroad rival

The Audi Allroad is something of an anomaly in the automotive world. Its competitors are limited to the recently released Volvo V60 Cross Country and perhaps the far cheaper Subaru Outback. The lifted premium wagon hasn't exactly done great for Audi, only selling a few hundred examples each month. Its best sales year was 2013, and even then, only 5,300 left US showrooms. Despite these limited prospects, word from Australia is that Mercedes-Benz is looking at launching its own competitor to the Allroad. "We are looking at every single niche, so we are studying this [Allroad] at the moment, but it is not confirmed," Matthias Luhrs, VP of sales and a member of the product management at MB, told Motoring.com.au. "We are looking obviously at C-Class and E-Class, but no confirmation at the moment." Fortunately, Luhrs recognizes that the Allroad isn't exactly a smash in the US. "In the US, no matter how long, short, high ... they don't like station wagons," Luhrs said, while adding that the Allroad concept is "developing quite successfully" in Italy and southern Europe. And for those hoping for a lifted C- or E-Class sedan, Luhrs also put the kibosh on that, saying, "We are not studying that." So what does this tell us? Well, it's still far from a sure thing that Mercedes will launch a lifted C-Class or E-Class Estate. And even if the company does go ahead with it, like the rest of the brand's long roofs (E-Class aside), don't expect to see it on US roads.

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.
