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.

How could a lifted Mercedes-Benz G63 AMG be more awesome? Add an axle

We are fully confident in saying that this will be the most amazing thing you see all day. First of all, it's a Mercedes-Benz G-Wagen - in AMG spec, no less. And it's being shown off in high-definition video glory, blasting through the desert, jumping over sand dunes, and generally being awesome. But here's the kicker: It has six wheels. Three axles. And they're all driven. Holy $%!#.
Under the hood is AMG's usual 5.5-liter twin-turbocharged V8, and total output is rated at 536 horsepower and 560 pound-feet of torque. That's impressive and all, but do keep in mind that the G63 6x6 weighs in at 8,322 pounds or, you know, the weight of two E-Class sedans. Combine that with its 18 inches of ground clearance, 37-inch tires and five locking differentials and you've got a vehicle capable of, well, everything you've ever imagined or will ever imagine for the rest of your life.
But the goodness doesn't stop once you open the doors. Oh, no. This thing is fit for a king - or a sheik, more appropriately - with ultimately luxurious seating for four. The rear bench seat has been removed in favor of two bucket seats with a fixed console in the middle, and the rear seats have been moved back beyond the usual B pillar to allow for more legroom.
