Petrolicious profiles mustard 1972 Mercedes-Benz 280 ready to go anywhere

The Mercedes-Benz sedans of the '70s and early '80s are certainly attractive models, but with their hard lines, the four-doors really don't have the graceful curves usually associated with a beautiful car. Instead, it's much more accurate to call these classic Germans handsome. The W114 chassis especially has a powerful stance about it with an upright grille dominating the front and long, flat surfaces elsewhere. Petrolicious takes a look at one man's journey to restore one of these posh vehicles in its latest video. Bernard Bredehorn grew up in the back of his grandparents' W116-chassis Mercedes 280 SE, and when he eventually got a classic of his own, Bredehorn ended up with a 1972 Mercedes 280. However, the sedan was in need of a complete restoration and sat for years in a friend's garage buried under parts. Bredehorn eventually excavated the car and brought it back to life in a very '70s shade of mustard yellow. Petrolicious shows why this classic Mercedes is now happy eat up many trouble-free miles on Germany's roads.

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.
