New Mercedes Unimog debuts to the cheers of little boys everywhere [w/video]

The Mercedes Unimog, the superhero villain of the off-road world that's just waiting to make the jump to Transformer, has been completely upgraded for its new generation. There are ten models, expanding the range and getting new designations across the traditional all-terrain series and the implement-carrier series. Panoramic cabins get more visibility, multifunction steering wheels and better dash clusters, improved HVAC and a three-mode central tire inflation system. Outside, there are new items like LED headlights and daytime running lamps in the bumper, roof-mounted windshield wipers and a front-camera monitor for the implement carrier.
The new engine lineup is compliant with Euro VI, featuring four- and six-cylinder BlueEfficiency engines putting out anywhere from 156 horsepower to 354 hp. Powerplant placement has also been tweaked, the chassis members getting a revised curve to place the engine a bit further back and lower, maintaining off-road clearance and lowering the Unimog's center of gravity. The new location of the engine means the cabin has more room, and the wheelbase is shorter. Combined with a higher turning angle, the Unimog has a smaller turning radius than before.
The implement carrier gets what's called a "synergistic traveling drive," the bonus being that drivers don't need to stop in order to use an attachment - a hydrostatic transmission works with the regular manual transmission at up to 31 kilometers per hour for seamless switching.

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 says it's tops in luxury sales for 2012, not BMW

It turns out that Mercedes-Benz North America has legitimate claim to being the top selling luxury nameplate in the US in 2012.
While sources such as Autodata had put BMW in the top spot, registration data from R.L. Polk shows that Mercedes customers registering new vehicles topped the Bavarian automaker in the most recent calendar year. Polk says Benz posted 274,123 registrations, compared with BMW's 268,498.
In terms of sales posted, BMW had bested Benz 281,460 to 274,134. But sales are recorded somewhat inconsistently from automaker to automaker. Some book the sales as soon as they are shipped from factory to dealer. There is perennial gamesmanship between the two German rivals, and the sales numbers suggest that BMW pushed out some extra sheetmetal to dealers in the last four weeks of the year.
