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.

Lewis Hamilton wins British GP, slashes Vettel's lead to 1 point

SILVERSTONE, England - Lewis Hamilton won his home British Grand Prix for the fourth year in a row on Sunday, while a penultimate-lap puncture slashed Sebastian Vettel's championship lead to a single point. The Briton's drive from pole to flag on an overcast afternoon was lonely, uneventful and dominant - in complete contrast to his Ferrari rival's afternoon - with Mercedes teammate Valtteri Bottas finishing 14 seconds behind to secure the one-two. "The support has been incredible this weekend. I am so proud I could do this for you all," said Hamilton, who threw himself into the fans for some crowd surfing after the podium celebrations. "The team were faultless this weekend, Valtteri did an incredible job as well, so it's the perfect weekend for us." Far behind in his wake, as Hamilton cruised to a 57th career win and soaked up the applause from an army of flag-waving fans, came sudden drama. Vettel, who had battled on worn tires but looked like securing the final podium position until the blowout, finished seventh after an emergency pit stop with a shower of sparks from the wheel rim. "There was no sign of that happening," said Vettel over the team radio. "There were vibrations but I had it for 20 laps and it didn't get massively worse. The tires didn't look great but they never look great." The German's Finnish teammate Kimi Raikkonen, who had been second before also being hit with a late puncture that sent Bottas and Vettel ahead of him, took third. At the halfway stage of the 20-race season, Vettel has 177 points to Hamilton's 176 with Bottas on 154. Hungary, a circuit where the Briton has won five times before, is next up. Hamilton became only the third driver, after his late compatriot Jim Clark and Frenchman Alain Prost, to win the British Grand Prix five times and the first to take four successive victories at Silverstone. Clark won four in a row in the 1960s, but one was at Aintree and another at Brands Hatch. Red Bull's Max Verstappen finished fourth, ending a run of retirements, with Australian teammate Daniel Ricciardo fifth after fighting through the field. Germany's Nico Hulkenberg was sixth for Renault and Force India pairing Esteban Ocon and Sergio Perez were eighth and ninth with Brazilian Felipe Massa securing the final point for Williams. Jolyon Palmer's miserable run continued, with Britain's only other driver on the grid failing to make the start after his Renault broke down on the formation lap with a brake failure.

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.
