Mercedes-Benz S63 AMG officially teased in mini video

The followup to the Mercedes-Benz S550, the S63 AMG, will sport a biturbocharged V8 that will likely turn out around 550 horsepower. The new engine is probably the 5.5-liter, biturbocharged V-8 that's been popping up in everything from the ML63 to the E63 AMG. The front fascia is more aggressive, which shouldn't come as a surprise, while a meaty exhaust setup can be found out back.
We managed to pick all that up from a short, 17-second video posted by MB. The original video that unveiled the S63 AMG has since been pulled down, making this YouTube clip the best look we now have at the new super sedan, at least until the Germans give up the goods for real.
Be sure to check out the video below, along with our original posting on the S63 AMG.

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 B-Class Electric Drive gets official US launch

It's finally time to plug in the first production Mercedes-Benz-branded electric vehicle in the US. The Daimler division, which also sells a few of its battery-electric Smart ForTwo vehicles here in the states, has officially launched sales of the Mercedes-Benz B-Class ED. Even better, the US will be the first market in the world to give the general public access to the new plug-in. As with many other EV debuts, the flyover states will have to wait a bit. Mercedes-Benz is only selling the B-Class ED in 10 coastal states, including California, Oregon, New York, New Jersey, Maryland and Maine, and hasn't said anything about when a broader release might happen. Earlier this month, the US Department of Energy rated the B-Class electric with an 87-mile single-charge range, which is comparable to that of the Nissan Leaf and BMW i3. The other shoe dropped, though, when it was revealed that the model has an 84 miles per gallon equivalent rating, which is about 30 percent less then both of those other EVs. The culprit for the model, which puts out 177 horsepower and has a base price of $41,150, is its heavier curb weight. Check out Autoblog's "First Drive" impressions here.
