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.

Recharge Wrap-up: Nissan reveals GT-R LM Nismo, NRG plans eVgo expansion

Nissan has officially revealed the GT-R LM Nismo LMP1 car. The hybrid Le Mans racer uses a biturbocharged 3.0-liter V-6 up front to power the front wheels, plus a kinetic energy recovery system for an extra boost. Football fans likely caught a glimpse of the car in Nissan's With Dad commercial that aired during the Super Bowl, but the company has a couple more videos that show the car off quite well provided below. "This is innovation that excites," Says Nismo president Shoichi Miyatani. "Sustainability is at the top of our agenda, and the technical regulations for Le Mans give us the freedom to pursue new ideas in this area." Read more at Green Car Congress, or in the press release below. The NRG eVgo charging network now operates 120 DC fast charging stations in California. 60 of those are "Freedom Stations," offering both CHAdeMO and CCS charging cables, and 52 more of these are in the works. NRG plans to expand the eVgo network to 25 US markets in the next two years (up from the current 10), including chargers in Tennessee, as well as linking cities along the near entirety of the East and West coasts.

As of now, the Supercharger network extends as far north as Edinburgh, southwest to Exeter, and to Maidstone in the southeast, which is just up the road from access to mainland Europe through the English Channel Tunnel. Tesla operates more than 1,600 Superchargers worldwide at over 300 stations, with 129 stations and more than 670 Superchargers in Europe. Read more at Hybrid Cars.

Mercedes teases IAA Concept for Frankfurt

Mercedes-Benz is being coy about the IAA Concept you see above. The Germany automaker admits its name is short for Intelligent Aerodynamic Automobile, but isn't letting out much more. In a very short statement, Mercedes describes the IAA as "two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design." Does that mean the IAA points the way forward for the next version of the brand's shapely CLS, which it also refers to as a four-door coupe? Probably, but we're not sure where the "Intelligent" part comes in. Will it be an electric machine that presages a competitor to the Tesla Model S? We'll just have to wait and see. One thing is for certain: The Mercedes IAA looks sleek. While the details of its design are shrouded in strategically placed shadows, we can clearly see a double-bubble roofline that flows seamlessly into a graceful hatch that reminds us of the Audi A7, which isn't a bad design to borrow cues from. The overall shape of the Intelligent Aerodynamic Automobile makes it look like bodywork shrink-wrapped atop the chassis as tightly as possible. We're keen to take a look at the IAA ourselves, and that's going to happen rather soon. Mercedes promises a debut at the Frankfurt Motor Show in the early afternoon (Eastern). Stay tuned. The Mercedes-Benz "Concept IAA" (Intelligent Aerodynamic Automobile) is two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design. World premiere.
