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.

Daimler rebuffs Geely offer to buy stake

HONG KONG/BEIJING - Daimler AG has turned down an offer from China's Geely to take a stake of up to 5 percent via a discounted share placement, as the German automaker has long been reluctant to see existing shareholdings diluted, sources with knowledge of the talks said. A stake of that size would be worth $4.5 billion at current market prices. Although Daimler declined the offer, it told Geely it was welcome to buy shares in the open market, the sources added. Carmakers in China have embarked on a flurry of dealmaking, as they scramble to boost production of electric and plug-in hybrid vehicles ahead of tough new quotas to be imposed by Beijing, which wants to reduce urban smog and lower the country's reliance on oil. People with knowledge of Geely's thinking said the company was keen to access Daimler's electric car battery technology and wanted to establish an electric car joint venture in Wuhan, the capital of Hubei province. Geely, which also owns Swedish car maker Volvo, is still hopeful it can secure a deal in some form over the coming weeks, they added. The two automakers met in Beijing in recent weeks at Geely's behest. There, the Chinese firm, formally known as Zhejiang Geely Holding Group, offered to take a stake of between 3 percent and 5 percent if Daimler would issue new shares at a discount, the sources said. It was not immediately clear what kind of discount for the shares Geely had in mind or whether Geely was interested in buying the shares on the open market. A spokesman for Geely declined to comment. A spokesman for Daimler said the company was "very happy with our shareholder structure at present", but added that it would welcome new investors with a long-term interest in the company. Shares in Daimler were up 1 percent in early Wednesday trade, in line with the broader market.DAIMLER ALREADY TIED TO BAIC, BYD Geely, which has a market value of some $32 billion, is the leading domestic brand in China with a 5 percent market share, according to an analysis by Nomura Securities. A stake of 5 percent would establish it as Daimler's third-largest shareholder behind the Kuwait Investment Authority and BlackRock, who hold 6.8 percent and 6 percent respectively, according to Reuters data.

Petrolicious shows Mercedes 280SL as architecture in motion

While still an absolute beauty today, the design of the pagoda-roof W113 Mercedes-Benz SL was revolutionary when it debuted. Moving away from the soft curves of the previous SL models, the all-new generation brought an upright, angular shape that was as much architectural as automotive. In the latest video from Petrolicious, owner and architect Daniel Monti expounds on the inspiration that he gets from his 1969 280SL's fantastic styling. The roof is the most famous design feature of this generation of SL. Look at the top from the front or back, and you can see a gentle, downward arc that evokes the look of a pagoda. That one styling element is also a fabulous counterpoint to a vehicle that is largely more angular than curvaceous. Petrolicious wonderfully illustrates how some of the SL's form-follows-function design aesthetic can be found in the architect's work in this video's heaping helping of mid-century modern goodness.
