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.

Mercedes AMG and Cigarette Racing debut 2,220-HP electric motor boat

Take the Mercedes-Benz SLS AMG E-Cell, stretch it and take off the wheels then make it float and you've basically got the just-unveiled Cigarette AMG Electric Drive Concept. Powered by an all-electric powertrain that offers 2,200 horsepower and 2,213 pound-feet of torque (and uses "numerous components" taken from the not-quite-as-yellow SLS AMG Coupé Electric Drive), the sleek concept is being called the "world's most powerful electric drive powerboat." What that means is a top speed of over 100 miles per hour from four 60-kWh lithium-ion batteries and two banks of six liquid-cooled, permanent-magnet synchronous electric motors. And the 240 kWh of total energy should provide plenty of juice out on the water.
Launched (but not literally) at the Miami International Boat Show today, the Cigarette AMG Electric Drive Concept is the result of a partnership between Mercedes-AMG and Cigarette Racing. The boat is 38 feet long (much longer than the 15-foot SLS) and is plastered with AMG branding on the sides and top of the bow above the matte chrome yellow paint (officially called AMG Electricbeam mango). Two 220-kW chargers can refill the batteries, dockside, in about seven hours.
The idea of a powerful electric boat is nothing new (Henrik Fisker talked about a plug-in hybrid watercraft late last year), but this is the first time we've seen Mercedes put its EV technology on the water. Anyone who's afraid of driving an EV in the rain should take note. Check out the complete press release below.

Mercedes was set to sell version of Nissan Titan, now Infiniti might instead

Mercedes-Benz Titan. Mercedes-Benz Frontier. Mercedes-Benz pickup truck. None of these things roll off the tongue particularly well. We'd like to think that's the reason Daimler opted to kill the idea of rebadged Titan and Frontier pickups from corporate ally Nissan. In reality, the execution before the Frankfurt Motor Show was due to more complicated issues.
Yes, Mercedes, byword for German luxury, style and quality, would have slapped a three-pointed star on a pair of Japanese pickup trucks that have failed to resonate with consumers in the world's largest truck market. That slapping of badges isn't much of an exaggeration, at least on the outside. According to the report from Road & Track, the truck's front clip would have been tweaked, but beyond that, the sheetmetal would have been unchanged. The interior would have received a more thorough going-over by the team at Mercedes, while the suspension and noise, vibration and harshness tuning would have also received significant attention.
The trucks would have ended up being sold through the light-commercial branch of Mercedes-Benz - the same folks that will happily sell you a Sprinter van - had the deal gone through. Issues arose, though, first with the engines. Mercedes wanted a wider range of powertrains to allow it to tune models for specific markets, while Nissan said it couldn't engineer the wide variety of engines that MB wanted to drop under the hood. For the smaller truck, meanwhile, MB was interested in a hybrid or plug-in variant, according to R&T, although this was also shot down by Nissan.
