Mercedes-Maybach Pullman stretches its way to Geneva

Mercedes-Benz is known the world over for producing luxury automobiles, but even among Benzes there's a hierarchy. The S-Class sits at the top of the Mercedes range, the Maybach at the top of the S-Class, and what you see here sits at the top of the Maybach line. It's the new Pullman limousine, and it arrives on the 50th anniversary of the original. Stretching a massive 21.3 feet, the new Mercedes-Maybach Pullman is even longer than the previous Maybach 62 by a full foot, and a good 3.5 feet longer than the standard-wheelbase Mercedes-Maybach S-Class, or two feet longer than the G63 AMG 6x6. In other terms, it's over a foot longer than the Rolls-Royce Phantom EWB, and the better part of a yard longer than even the Cadillac Escalade ESV. Heck, you could just about fit Benz's other flagship, the Mercedes-AMG GT, inside the new Pullman's 14.5-foot wheelbase. As if that's not enough, it also stands 3.9 inches higher than a standard S-Class to the benefit of its imposing presence and interior space. Should you be so fortunate as to be graced with an invitation to step inside, you'd find an interior entirely clad in leather with four seats: two recliners and two fold-down seats facing backwards. Those principal rear seats can recline between 19 and 43.5 degrees and offer an extensive array of individual adjustments to cater just-so to the occupants' individual preferences. Ingress and egress are enabled by larger rear doors that open in front of – instead of next to – those rear seats to enhance the privacy of the traveling dignitaries, who will be able to monitor the state of affairs through the analog thermometer, speedometer and clock mounted in the roof liner. They'll also enjoy privacy thanks to the electrically operated glass partition wall with an 18.5-inch monitor mounted in front of it and a choice of Burmester sound systems. Long the favorite of heads of state and captains of industry, the new Pullman will be unveiled at the Geneva Motor Show now just weeks away. We don't doubt that Mercedes will offer its customers a choice of engine options (as long as they're capable of motivating the new Pullman's assuredly substantial heft), but most suitable to the task will of course be the 6.0-liter twin-turbo V12 with its 523 horsepower and 612 pound-feet of torque.

Mercedes Vision Tokyo Concept is a minivan for millennials [w/video]

Mercedes-Benz believes that the next generation of drivers would much rather interact digitally with their machines than actually be behind the wheel. To satiate the desires of these tech-obsessed passengers, the company reimagines the minivan as a rolling, autonomous lounge called the Vision Tokyo Concept. The silver lozenge debuts at the 2015 Tokyo Motor Show. With its rounded edges, plentiful glass, and satiny Alubeam paint, the Vision Tokyo looks like a minivan from the high-tech future out of a William Gibson story. Up front, the windshield wraps all the way around, and the side glass is screen-printed in silver for privacy. The massive grille is illuminated and can even show the sound pattern of the music playing inside. Meanwhile at the rear, red LED lights surround the oval window. While the exterior is fairly minimalist, the Vision Tokyo puts its biggest emphasis on pampering the five passengers inside. They enter through a massive gullwing door in the concept's side, and rather than traditional rows of seats, there's a wraparound couch. Once comfortable, occupants can use LED screens on the walls, and in a truly sci-fi touch there's a holographic entertainment system in the center. Should someone actually need to drive, a seat can also deploy from the couch, and a steering wheel slides into position. Riding in this metallic chariot at least isn't too bad for the environment. The powertrain combines a hydrogen fuel cell and batteries capable of inductive charging. In total, the combo would offer a claimed range of 609 miles – 118 miles purely on electricity and 491 miles from the H2. That kind of driving distance should keep the digital party inside rocking for quite a wild night. Check out the high-res image gallery above and the video below. And for more, stay tuned for our live coverage from the Tokyo Motor Show. Mobile club lounge for young, urban trendsetters Mercedes-Benz Vision Tokyo: Connected Lounge Stuttgart/Tokyo. The Vision Tokyo is the latest trailblazing spatial experience to come from Mercedes-Benz: its monolithic structure, futuristic design idiom and unique lounge ambience in the interior define it as luxurious, young and progressive – thus making it a fitting tribute to the sophisticated megacity and trendsetting metropolis that is Tokyo.

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.
