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-Benz V-ision e Concept ups the plug-in hybrid van game

The various V-Class vehicles from Mercedes-Benz don't get a lot of press around here, but when the German automaker brings something as unusual as the Concept V-ision E (yes, there's a dash in the name) to the Geneva Motor Show, we're happy to make an exception. The standard powertrain V-Class was first unveiled in Geneva last year and it returns in 2015 as a decidedly Daimleresque take on a plug-in hybrid van with a whole heap of cool new technology under the hood. C'mon, you know you want a luxury plug-in hybrid van. Well, if you think you don't want a van like that, listen to the specs and maybe you'll change your mind. It's got an all-electric range of up to 31 miles (if you're going no faster than 50 mile per hour), roughly 78 miles per gallon equivalent (based on the stated fuel economy of 3.0 liters burned per 100 kilometers) and a top speed of 128 mph. That should be plenty to get the basketball team to the tournament on time and in style. The powertrain has a total system output of 333 horsepower thanks to a four-cylinder engine and a 90-kW electric motor. If those numbers sound vaguely familiar, that's because Mercedes said it's "the same advanced drive system" as what's found in the Mercedes-Benz C 350 e, even though some of the performance figures differ. Stylistically, Mercedes has pulled no punches, adding two sun roofs, a real wood floor, nappa leather and executive seats along with something shiny and silver called "designo titanium alubeam" paint. In short, this is an everything-and-the-kitchen-sink approach to PHEV design, and we like it. It's just a concept, though, so don't go asking to buy one just yet. Instead take a better look in the gallery above and dream of going to the auto show prom in a van like this. V-Class concept car with a PLUG-IN HYBRID drive: Mercedes-Benz Concept V-ision e - Higher Performance at Lower CO2 Emissions Stuttgart, Mar 03, 2015 At the Geneva International Motor Show the Concept V-ision e from Mercedes-Benz presents a preview of the great variety of development potential offered by the V-Class. The concept vehicle combines environmentally friendly performance with the lightness of modern luxury. The most advanced PLUG-IN HYBRID technology available ensures extremely powerful propulsion in the model, as the highly efficient drive-system duo consisting of a gasoline engine and an electric motor delivers total system output of 245 kW (333 hp) and system torque of up to 600 Nm.

Daimler and Volvo could jointly develop internal combustion engines

BERLIN — Luxury German carmaker Daimler and Volvo, owned by China's Geely, are considering cooperating to cut the costs of developing combustion engines, a magazine reported on Sunday, citing unnamed company sources. The Automobilwoche weekly cited a Volvo manager as saying there were initial talks with Daimler, but no concrete plans, while a company spokesman said it was too early to talk about firm projects, although it was not excluding anybody. A Daimler spokesman said the company's cooperation with Geely, which owns a 10% stake in the German carmaker, was developing in a positive way, but declined to comment further. Global tariffs, accelerated by a trade war between China and the United States, as well as higher investment requirements for electric and autonomous vehicles, are forcing carmakers to seek new ways to cut and share costs. In October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply in-house brands and also potentially others with next-generation combustion and hybrid engines. Automobilwoche said this new division would start operating by the end of March, which could be a possible starting point for cooperation with Daimler, while a further step could be a partnership to develop electric power trains. Geely and Daimler have said they plan to build the next generation of Smart electric cars in China through a joint venture and the two companies are also cooperating on a premium ride-hailing service in China. Geely bought Volvo Cars in 2010 from Ford, allowing the Swedish brand to operate on an arms-length basis. But in recent years, it has deepened cooperation between the two brands. Volvo already supplies engines to some Geely-branded vehicles, sharing technology through Geely's Lynk brand. Both companies share and develop common vehicle platforms.
