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.

XCAR marks 20-year anniversary of Senna's passing with Mercedes 190E Cosworth

While the automotive world is focusing on the twentieth anniversary of Ayrton Senna's death, there was much, much more to the legendary driver than his untimely passing at the 1994 San Marino Grand Prix.
XCAR has the story of a younger Senna, who, by a stroke of luck, found himself matched up against a veritable dream team of nine Formula One champions, not to mention a cadre of German touring car aces. A "probably still pissed (drunk)" James Hunt, hard-driving Niki Lauda and future champion and rival Alain Prost, were in attendance for the one-off, spec race, which was put on by Mercedes-Benz, in honor of the opening of the Nürburgring's Grand Prix circuit. And Senna was on hand with the explicit goal of besting them all.
Each driver was handed a lightly modified, but brand-new 190E 2.3-16 Cosworth, a car that can best be though of as the distant ancestor of the lovable C63 AMG. As for the race itself, well, it was sort of like an introduction of what the sport could come to expect from the Brazilian.

Cadillac, Daimler execs take swipes at Tesla

Despite the financial ties between Daimler and Tesla Motors, at least one Mercedes exec thinks the electric automaker doesn't have a bright future. And over at Cadillac, the message is that Tesla doesn't pose a threat but offers the luxury arm of General Motors more of classroom experience. The Mercedes story runs like this. Mercedes-Benz USA president and CEO, Steve Cannon, said at the New York Auto Show last week that Tesla has "no network" and only offers "little shops that don't have service capacity." He also said: "Folks are buying a Tesla now because they're kind of cool, but if you're a Tesla buyer, you have to have multiple cars. With Mercedes, you have a whole network. You've got no worries. ... Tesla is great, but you've got plenty of well-established brands that mean luxury, like Porsche or Mercedes-Benz, and how long do you think we're going to wait and let Tesla be out there alone [selling premium electric cars]?" "Treehuggers do not buy new luxury cars" – Uwe Ellinghaus For Cadillac's global chief marketing officer, Uwe Ellinghaus, Tesla's EV success represents little other than "a great opportunity and a learning exercise for all of us, and will help us traditional manufacturers to think twice about electric mobility." He added that, "I am not afraid of Tesla. ... There is no willingness to really sacrifice on the traditional qualities of a luxury car. These are not cars for treehuggers, as treehuggers do not buy new luxury cars." Ellinghaus made the comments during a panel discussion at the 2014 Automotive Forum. Perhaps the lesson of Tesla's offer of free Supercharging to Model S owners is what led to Cadillac to recently announce a deal with Chargepoint that gives ELR drivers access to that company's 16,500 charging stations. Read more details on that below. Cadillac and ChargePoint Bring EV Customer Luxury Driving Experience World's largest, most open electric vehicle charging network available to ELR drivers 2014-04-16 NEW YORK – Cadillac today announced a partnership with ChargePoint, the largest and most open electric vehicle-charging network in the world.
