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 CLA stars in sweeping short with supermodel Karlie Kloss

The Mercedes-Benz CLA earned itself a spot on our list of the top five unveils of the 2013 Detroit Auto Show, and for good reason. The German luxury compact is the first small car from the Silver Arrow that looks suitably premium inside and out. Nowness.com has turned out a new video of the CLA featuring super model Karlie Koss in the lead role. We aren't entirely sure what the premise is, but from what we can tell, it looks as if the CLA comes to life and proceeds to be a giant jerk.
After Koss stops to take a closer look at a white horse, the CLA gives the supermodel the old stop-and-go treatment before leaving her on the side of the road. Eventually, the sedan makes nice, but Koss has to ride shotgun instead of taking the controls herself. You can check out the video below to see for yourself.

Leaked dealer docs say Mercedes-AMG GT S to start at $129,900

The 2016 Mercedes-AMG GT exists as one of the most hotly anticipated European sports coupes to come along in quite some time. Offering some beautifully swoopy styling and a twin-turbocharged 4.0-liter V8 with 503 horsepower and 479 pound-feet of torque in S trim, there's really not much to dislike about it. However, until now, the price of this gorgeous German remained a mystery. According to a leaked letter to dealers obtained by Jalopnik, pricing for the 2016 GT S model allegedly starts at $129,900, and the coupe reportedly comes standard with a Nappa leather interior, Collision Prevention Assist Plus, Mercedes' COMAND infotainment system, Parktronic and Burmester sound system. The document also says more info about specific option pricing would be released in a few weeks. We've already compared both trims of the GT to the venerable Porsche 911 because the coupes seem like such natural competitors. Knowing the possible price adds one more factor to consider, though. In terms of performance, the GT S basically slots just below the 911 Turbo. However, if this amount is correct, then the starting cost is about $20,000 less than the turbocharged Porsche. While on paper the Mercedes lags somewhat in acceleration and power, it also arguably offers buyers a bit more style. This is definitely turning out to be an interesting fight between these two Germans. Related Video:
