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.

Vision Mercedes-Maybach 6 to debut in Monterey

Mercedes surprised the car world last week when it teased an enormous, Maybach-badged coupe concept. Now we have a name and a debut date. Mercedes released the info in a second teaser image posted to its Facebook page. Called the Vision Mercedes-Maybach 6 – "Vision" equals concept and "6" denotes the length in meters – the new two-door will debut at Pebble Beach on Thursday. So yeah, here's another reason to get excited about Monterey Car Week. As for the teaser image, it's a head-on shot as opposed to the profile view that Mercedes released last week. The new view supports our theory that the super-skinny mirrors are cameras, and the shot also reveals new styling touches. The most noticeable are the very thin, un-Mercedes-like headlights – they flank a prominent, heavily polished waterfall grille that marks a significant departure from recent Mercedes products. A traditional Mercedes hood ornament sits above the grille's small "Maybach" designation. Kicking up the exposure in Photoshop doesn't reveal too much more detail – unlike last week's profile image – aside from a set of chrome strips that run along the sides of the hood. Autoblog's Monterey Car Week crew ships out for the left coast soon – expect more on the festivities, including the Vision Mercedes-Maybach 6's debut, later this week.
