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.

Aston Martin tipped for F1 return with Red Bull, Mercedes

Aston Martin could be plotting a return to Formula One for the first time in over half a century. And not as a backmarker, either. That is, at least, if the latest rumors materialize. While most automakers that participate in F1 do so as either a team owner (like Ferrari and Mercedes) or as an engine supplier (think Renault or Honda), the rumored Aston Martin deal would take a different approach. According to Autosport, the proposal would have the Red Bull Racing team run Aston Martin branding – but not its engines. Those would be provided by Mercedes, just like the engines in the British marque's upcoming slate of road cars. In that regard, the deal would not be unlike the one which Red Bull currently has with the Renault-Nissan Alliance, which sees the team running Renault engines and Infiniti branding. Andy Palmer was a pivotal figure in brokering that unusual arrangement when he was working for Carlos Ghosn, and is now tipped to be brokering a similar deal in his new capacity as Aston Martin's CEO. Though Aston has found glory in sports car racing (including Le Mans and its various associated series), it was never much of a contender in grand prix racing. It competed in a handful of races in 1959 and 1960, but never achieved results worth bragging about. Aston was rumored to be plotting a return when David Richards sat as chairman of the company, having run Aston's racing program as well as Honda's F1 team previously. Those rumors, however, never materialized. Whether this time 'round gains any traction remains to be seen - Aston Martin declined to either confirm or deny the reports when reached for comment by Autoblog. Red Bull has been growing increasingly dissatisfied (and increasingly vocal about its dissatisfaction) with Renault engines over the past couple of seasons. Though the two parties won four back-to-back world titles together, things took a noticeable step backward after the new turbo engine regulations took hold for the 2014 season. Nissan/Infiniti and Red Bull are contracted to continue collaborating until the end of next season. After that is when the new Aston deal could take hold, and Mercedes is reportedly keen on the idea so that it could add another customer to its F1 engine supply business and offset the costs of development. That could effectively prove the end of Renault in F1 (at least for the time being). Aside from Red Bull, the French automaker currently supplies only that outfit's sister team Toro Rosso.

Mercedes plotting E-Class Maybach, next A-Class for the US?

Mercedes-Benz has opened 2015 by hinting at a host of new products. Dieter Zetsche nudged the idea that there'll be a Maybach-branded SUV. AMG chief Tobias Moers told Motor Trend that "We want to be seen by the public on the same level as the other sports car maker in Germany" when asked if his crew was working on a car to rival the Porsche 918 Spyder. That and a few other tidbits have people thinking that we'll eventually see some sort of celestial AMG supercar. The latest handful of hints came from Mercedes USA CEO Steve Cannon during an interview on the marque's move to Atlanta. Cannon told Automotive News that we'd "see more from the Maybach brand," leaving the impression that there "could" be an E-Class draped in the superluxury trim. If such came to pass, there's plenty of pricing room between the E and the S-Class to slot a higher trim in. The top non-AMG E-Class starts at $62,350, the S-Class opens the bidding at $94,400. Even if you slapped the E-Class with the $23,000 premium it takes to make an S600 a Maybach S600, you've still got plenty of breathing room between the midsized and full-sized sedans. At the antipodal end, Cannon told AN that we could get a front-wheel-drive Mercedes smaller than anything here right now. That leaves the A-Class, since we've already got the B-Class. Getting the next-gen A-Class here would help with CAFE numbers, and since it will be built in the new factory in Aguascalientes, Mexico it won't have far to travel to get here. We're told it won't be like the current car, however; Cannon said, "The A-Class will change from what you have seen and from what you are used to." We hope that's a good thing, because we really like the current car. Related Video:
