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.

13-year-old boy swipes dad's Mercedes, drives across Europe

After an argument with his adoptive parents that resulted in them taking away his mobile phone, an angry 13-year-old boy ran away from his home in Italy and headed straight to Poland to meet his biological sister. But instead of taking the train or hitching a ride, like most on the run, the young man (an accomplished go-kart racer and car enthusiast) grabbed the keys to his father's Mercedes-Benz and jumped behind the wheel for an impromptu road trip.
With less than 200 euros (about $270) in his wallet and a passport in his pocket, the youngster managed to put more than 500 miles between himself and his distraught parents, crossing two international borders in the process, before German police nabbed him just shy of the Polish border. According to reports, the vehicle was tracked - it wasn't his driving that alerted authorities to his location.
Reunited with his mother and father, who traveled to Germany to retrieve both their son and the vehicle, the young man apologized and acknowledged his error. As a result of his actions, social workers will increase checks on the family and we can be sure his parents are now hiding the keys.

Experience the New York Auto Show by drone

The Autoblog team recently returned from wildly running around the Javits Center to cover all the news and debuts at the New York Auto Show. Sometimes, it's nice to take a more serene look at the exhibition floor, though, and the event's organizers are providing that exact opportunity by flying a drone through the hall. Combined with the down-tempo music, this clip feels like a form of automotive meditation. If you're going to miss the show in the Big Apple, the drone also provides a good overview at the exhibition floor, especially at the stands from Lexus, Buick, Dodge, Mercedes-Benz, Toyota and BMW. Plus, it's a fun way to see some vehicles from a completely different angle than they ever appear on the road.
