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.

Daimler buying 12% stake in Beijing Auto

Daimler and Beijing Automotive are officially going steady, with the German company set to take a 12-percent stake in the Chinese brand tomorrow. The two are already tied up in a Mercedes engine plant in Beijing, of which BAIC will increase its stake in, from 50 to 51 percent. Daimler will also get two seats on the Chinese company's board. BAIC may also gain the ability to produce cars on Mercedes-Benz platforms, according to Automotive News Europe.
The investment in BAIC comes ahead of that company's initial public offering, according to a report form Bloomberg, which indicates the deal will be inked tomorrow in the Chinese capital. According to the report, if the circumstances are right, BAIC may turn around and invest in the Germany company "soon."
It's not entirely clear just how much the 12-percent cut is costing Daimler, although it seems reasonable to assume that, as it's ahead of the IPO, the parent company of Mercedes is getting a bit of a bargain.

Dartz promises own 6x6 G-Class with golden shishas and a dining room

So you didn't really think Dartz Motorz was going to let the limited-production, 544-horsepower Mercedes 6x6 G63 AMG go without a challenge, did you? Picking up the gauntlet as only Dartz can, the Russian dream-makers have come up with the Sahara G-eopard, supposedly a special request from a buyer to make one of the 'standard' six-wheelers "more opulent and insane."
That means the vehicle from the factory gets extended by about a foot (30 centimeters), coach doors in the rear, a "yacht floor" and air conditioning that runs on its own power source, Asanti 24-inch Gold Bullion wheels and a water dispenser with Russian diamonds, which the owner will need to fill the golden shishas (hookahs) in the portable smoking room. That's right, you heard the man: a portable smoking room. Where the occupants will retire when they're finished in the portable dining room. Of course.
Yes, it will even have leopard spotting painted onto its nano-coating, and so much more. You can check out the press release below from the source. Try not to be jealous.
