Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

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.
