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.

Lewis Hamilton takes pole as Mercedes speed stuns rivals

MELBOURNE, March 16 (Reuters) - Formula One champion Lewis Hamilton blazed to a record-extending eighth pole and sixth in succession at the Australian Grand Prix on Saturday to lead Valtteri Bottas to a Mercedes sweep of the front row of the grid. Hamilton struggled with a brake problem during the frenetic final session at Albert Park but edged his Finnish team mate by 0.112 seconds with a searing second lap of one minute 20.486 seconds that set a record at the lakeside circuit. The one-two punch by Mercedes left Ferrari and their championship rivals stunned, with Hamilton's chief challenger Sebastian Vettel, who qualified third, more than seven-tenths of a second off the five-times champion's pace. "Oh man, I'm shaking it was so close out there," Briton 34-year-old Hamilton said after extending his pole record to 84 on a warm, sunny afternoon in Melbourne. "Coming from winter testing, we had no idea where we would be. We were hoping to be where we are ... Valtteri did an exceptional job out there, it was very close." Hamilton matched Ayrton Senna and Michael Schumacher for the record number of poles at a single race track. Senna took his eight at Imola, with Schumacher dominating the Suzuka circuit. Four-times champion Vettel, bidding for a third successive win at Albert Park, was separated from his new team mate Charles Leclerc by fourth placed Max Verstappen of Red Bull. It would have felt like 'deja vu' for Ferrari, having trailed Mercedes by nearly seven-tenths of a second in qualifying at last year's race. "Certainly Mercedes are the clear favorite," Vettel told reporters with a touch of resignation. "I'm certainly surprised (by their pace), I think everybody is, probably even themselves." "I think, there is still a bit of margin (to improve) but certainly the gap is there today, and it was a surprise," the four-times champion told reporters. "We didn't expect it coming here but now it is that way. ... Obviously there is a lack somewhere, because we are too slow – but didn't feel like it." German Vettel's new team mate Charles Leclerc qualified fifth fastest behind Red Bull's Max Verstappen but the highly regarded 21-year-old was harder on himself than the car. "I'm not happy with myself. I didn't do the job in Q3, which is a shame," said the Monegasque, who locked up in turn one of a "messy" second lap.

Daimler could sell off Li-Tec's EV battery business

Five-plus years may have been about enough time for Daimler AG to know whether it wanted to be in the battery-pack production business. The Mercedes-Benz parent may stop making electric-vehicle batteries and ultimately sell its Li-Tec battery-cell factory in Germany within two years, according to Bloomberg News which cites Manager Magazin. The beneficiary may be LG Electronics, which would likely take over battery-production duties for models such as Daimler's Smart ED battery-electric vehicle. Daimler is taking a number of steps to improve profit margins, which are thinner than those of its German rivals like BMW. Like its German competition, the company has lagged behind companies such as Nissan, Renault and Tesla Motors in terms of aggressively pursuing growth via plug-in vehicle sales. Daimler spokesman Hendrik Sackmann, in an e-mail to AutoblogGreen, would only say that the battery business is growing "rapidly" and that Li-Tec is developing "according to our plans." "Regarding Li-Tec, we are working on a concept for the future line-up," he added. "The battery cells for the successor of the Smart electric drive won't be provided by Li-Tec." Daimler in 2008 launched Li-Tec as a joint venture with Evonik, though Daimler recently put plans together to buy out Evonik's 50-percent share of Li-Tec, Bloomberg reported last month. Evonik's role was manufacturing electrodes and separators for batteries. Daimler also said last fall that it was looking to cooperate more extensively with Tesla in regards to electric vehicle development. The two companies first said they'd work together in 2009.
