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-Benz G500 4x4 is a 6x6-2 [w/video]

In terms of truly badass off-roaders, it doesn't get much cooler than the Mercedes-Benz G63 AMG 6x6. After all, the thing has three axles powering six wheels, not to mention an AMG-tuned V8 that makes the truck pretty much unstoppable. Call it an exercise in excess, if you will, but we call it super cool. And now, at the 2015 Geneva Motor Show, Mercedes is showing off a slightly less outrageous version of its insane off-roader, called the G500 4x42. And by "slightly less outrageous," we pretty much mean, "with one fewer axle." Sure, there have been some other changes, too – namely under the hood, where the AMG's twin-turbo 5.5-liter V8 has been removed in favor of a new, twin-turbo 4.0-liter V8, good for 422 horsepower and 450 pound-feet of torque. Off road, this thing should be a freaking beast. It can ford depths up to 39 inches, the approach angle is 53 degrees, departure is 54, and the breakover is 47. Talk about all-terrain. Plus, it looks freaking cool, with 22-inch wheels on 325/55-series tires (which can be swapped for a set of 18-inch wheels on 37-inch beadlock tires). We even love the lime green paint it wore upon debut, and are kind of sad the Geneva showcar is painted in this less-awesome silver. Either way, it's certainly a creation to behold. Check it out. Near-series show car G 500 4x42: The G-Class Squared Stuttgart, Feb 21, 2015 -- Only a G-Class can be better than a G-Class. This is the credo followed by the developers with the Mercedes-Benz G 63 AMG 6x6, and they are now stepping up a gear with the G 500 4x42. The basic recipe for this overcomer of everything is simple: take the superior all-wheel-drive powertrain including portal axles from the 6x6 – take away one axle – and blend it all with a newly-developed variable chassis and the series-production G-Class body. A large pinch of V8 power with 310 kW (422 hp), a set of 22-inch 325/55 R 22-sized wheels, carbon-fibre body parts and then just gourmet ingredients from the seductive designo Exclusive range for the interior – and the 5-star menu for all off-road enthusiasts is ready. A new addition to the extreme G-Class model family: the G 63 AMG 6x6 has a model brother in the form of the G 500 4x42. The near-series show car is a new highlight in the superlative-rich history of the G-Class and blends all the advantages of the model series.

First official shot of Mercedes S-Class Coupe leaks out

With the official debut for the Mercedes-Benz S-Class Coupe expected tomorrow, it shouldn't be a surprise that some clicky fingers have already managed to uncover an official image of the car before the unveiling. Outside of this sole image, though, there's precious little detail on the new car.
First posted by Autofilou and then picked up by WorldCarFans, the production S-Class Coupe isn't far off from the concept car we saw a few months back in Frankfurt. Like the concept, the leggy production model appears related, albeit distantly, to the S-Class Sedan. The hood and front fascia are longer and lower, befitting of a two-door, while the character lines in the profile are more pronounced. Obviously, the beltline and slim, B-pillarless greenhouse are coupe-only items. We can't see any details on the back of the car, although it does appear that the long hood has a correspondingly short rear deck.
We'll have all the details on the official replacement for the CL-Class when it makes its full debut tomorrow. Until then, what do you think of this lone image? Does it appear that Mercedes has got it right? In terms of design, where would you rank this with the departing CL-Class? Have your say in Comments.
