2014 Mercedes-Benz C63 AMG Edition 507 still lights our fire

The current Mercedes-Benz C63 AMG may be in the autumn of its years, but it's still one of our very favorite sport sedans. Ever. Yes, its paddle-shift transmission may not always follow orders, but with stupendous levels of thrust from its charismatic naturally aspirated 6.2-liter V8, ebullient rear-wheel-drive dynamics and that noise, we frankly don't care that it's getting on a bit.
As a sendoff of sorts for the current generation, Mercedes-Benz has just introduced a new Edition 507 model at the Geneva Motor Show, with 507 horsepower and 450 pound-feet of torque - an increase of 56 horses over the standard car. Mercedes credits the substitution of low-mass internals from the SLS AMG gullwing for the power bump, a tactic shared with the AMG Development Package upgrade that has been subsumed by this Edition 507. 0-60 is quoted at 4.1 seconds and top speed at 174 mph.
The Edition 507 borrows its aluminum hood from the C63 AMG Black Series Coupe, along with spidery new 19-inch wheels in either titanium gray finish or matte black with shiny rim flanges. As seen on our gallery car above, a sports striping package is also featured, as are glossy black grille, daytime running lamps, spoiler and mirror caps.

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.
