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.

Highlights from the Goodwood Festival of Speed, including the McLaren P1 and a Ford Transit running the hill

The sole purpose of this post is as a time-waster, and since you shouldn't have to work to waste time, we've done it for you. In the numerous videos below you'll find cars that have lately been in the news tramping all over the grounds of Lord March's estate in Goodwood, England.
There's the McLaren P1 heading up the hill, the Jaguar Project 7, then a casually-driven Porsche 917 followed by an even-more-casually-driven Porsche 956, topped off by a Porsche 936 that is anything but casually driven. The next round is the flame-spitting Peugeot 405 T16 Pikes Peak from Climb Dance, a camera mounted on the Peugeot RCZ R after it showing you what the whole, uninterrupted run up the hill looks like. For a real head-turner, we couldn't embed it but there's Andy Reid blasting up the hill in a Ford Transit Supervan with a Cosworth 3000 V6 engine.
The modern racing contingent has Allan McNish doing the hill in the Audi R18 e-tron quattro he used to win Le Mans and Lewis Hamilton making lots of tire smoke in the Mercedes-AMG Petronas MGP-W02. For comparison, that's followed by Nick Heidfeld's record-setting run up the hill in 1999 in the McLaren MP4/14 . The classic racing contingent is headlined by 71-year-old Giacomo Agostini on an MV Agusta.

Mercedes has already booked 30k orders for new S-Class

When Toyota snags 30,000 Corolla orders over a three-month span, it's entirely possible we're in the midst of a global economic collapse and that the end is nigh. That's because the scale for Toyota is so very large. Mercedes-Benz, on the other hand, operates on a much smaller scale, particularly when we talk about its higher-end models, like the S-Class.
In 2012, Mercedes sold 65,000 of its flagship sedans in Germany and the EU. That's 178 units per day, for 365 days. Based on that, you can imagine the excitement at Stuttgart when it accepted 30,000 orders for the new S-Class in just three months. That's an average of 333 per day on a continent with a notoriously shaky economy. Now, admittedly, this enthusiasm could wane as the refitted S-Class becomes more common and Mercedes achieves market saturation in Europe's many chauffeur and livery services, but Mercedes isn't choosing to look at it that way.
"The new S-Class has already jumped back into the lead in terms of new vehicle registrations in Germany and its neighboring European countries," Mercedes-Benz head of sales and marketing, Ola Kaellenius, said in a statement last week.
