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.

Zetsche's CEO tenure extended through 2016 at Daimler

There appear to be two takes on Daimler CEO Dieter Zetsche having his contract extended for three more years, to 2016. A report in The Detroit News quotes the chairman of Daimler's supervisory board, Manfred Bischoff, talking up the stability at the top, "With today's extensions of the contracts of Dieter Zetsche and Thomas Weber, we are maintaining the important continuity at the top executive level." Bischoff also stated that that Zetsche has a plan to "further enhance Daimler's overall performance."
Over at Reuters, though, the three-year extension was seen as a lack of complete confidence in Zetsche's plans, since his contract was supposedly meant to be extended by five years. A spokesman said the board decided to extend executive contracts by only three years if the person was 60 or would turn 60 during the contract, but that was news to observers. Zetsche wants to make Mercedes-Benz the top selling luxury manufacturer globally by 2020, but has fallen to third place behind Audi and BMW. It hasn't held the top spot 2005, and investors judged it valued at half that of BMW at the end of 2012 once Daimler's truck business was subtracted.
Analysts cites the fact that Daimler stock hasn't bested its rivals but twice in twelve years, and that the company revised its profit target downward last year by nearly one billion euros, warning of stagnant earnings this year and will miss its original margin target for 2013.

Test drive the Mercedes SLS AMG Electric Drive with Chris Harris

It's hard to not like the Mercedes-Benz SLS AMG GT. The all-aluminum coupe is fitted with a wonderful naturally aspirated 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque. Not only does the burly combustion engine launch the two-seater to 60 miles per hour in less than four seconds, but it does so with one of the world's greatest exhaust soundtracks as it roars, burbles and cackles down the road.
But what happens when Mercedes-Benz takes away the V8 and its accompanying fire-burning song? Stripped of one of its most appealing assets, does the SLS lose its soul?
Chris Harris recently had the opportunity to take the Mercedes-Benz SLS AMG Electric Drive for a track spin in Europe. Sans gasoline, but with four electric motors providing a combined 740 horsepower (737 pound-feet of torque), all-electric all-wheel drive coupe uses sophisticated torque vectoring and a multi-mode operating system to put oversteer - drifting! - back into the equation. Fun? You bet. See for yourself, below.
