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.

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.

Five B-Class F-Cells go from SF-LA using public hydrogen stations

California's hydrogen islands in Los Angeles and San Francisco finally got the bridge they needed to become the "Hydrogen Highway." With the completion of a permanent public station in Coalinga built by FirstElement Fuel, 205 miles north of LA, 183 miles south of SF, fuel-cell-vehicle owners can complete the road trip without worry. Mercedes-Benz did just that with five B-Class F-Cell customers, spending three days covering 1,000 miles and filling up only at public permanent stations in Burbank, Coalinga, West Sacramento, and Emeryville. Mercedes says there are ten stations in California now, but more than 40 are scheduled to open in 2016, and about ten more every year after that through 2023, when there should be 123 open stations. The company's US fuel-cell fleet is 70 strong and has covered more than two million miles in the five years they've been on the roads here. On average that means each car has driven just 5,714 miles per year, but that number should go up now that they can stretch their hydrogen stacks. The press release below has more information. Nearly 1,000 fuel cell electric miles: Crossing California on Hydrogen - Five Mercedes-Benz B-Class F-CELL complete emission-free drive from Los Angeles to Northern California while only filling up at public hydrogen stations - "California Hydrogen Highway" is connecting the dots - U.S. F-CELL customers have accumulated over 2 million miles since 2010 Stuttgart, Oct 27, 2015 - Mercedes-Benz B-Class F-CELL customers ventured beyond Southern California last week for the very first time, while only filling up at existing public hydrogen stations along the route from Los Angeles to San Francisco. The opening of a new hydrogen station in Coalinga along the I-5 corridor made this opportunity possible. A team driving five B-Class F-CELL refilled at four permanent hydrogen fueling stations located in Burbank, Coalinga, West Sacramento and Emeryville, accumulating nearly 1,000 miles over the course of their three day trip. Three F-CELL customers were accompanied by a team from Mercedes-Benz Research and Development North America based in Long Beach. The purpose of this unique road trip was to highlight the growing hydrogen station network and to show that the vision of the California Hydrogen Highway is becoming reality. Early adopter Loki Efaw who has been an F-CELL driver since 2011 believes fuel cells are the future: "I don't want a car that only takes me to work and back before I have to plug it in.
