Petrolicious shows Mercedes 280SL as architecture in motion

While still an absolute beauty today, the design of the pagoda-roof W113 Mercedes-Benz SL was revolutionary when it debuted. Moving away from the soft curves of the previous SL models, the all-new generation brought an upright, angular shape that was as much architectural as automotive. In the latest video from Petrolicious, owner and architect Daniel Monti expounds on the inspiration that he gets from his 1969 280SL's fantastic styling. The roof is the most famous design feature of this generation of SL. Look at the top from the front or back, and you can see a gentle, downward arc that evokes the look of a pagoda. That one styling element is also a fabulous counterpoint to a vehicle that is largely more angular than curvaceous. Petrolicious wonderfully illustrates how some of the SL's form-follows-function design aesthetic can be found in the architect's work in this video's heaping helping of mid-century modern goodness.

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 releases US-spec 2014 Sprinter details

Last week, Mercedes-Benz released the details for the updated 2013 Sprinter intended for global markets, but this week it has announced what changes are being made to the US-spec version of the van for the 2014 model year, including the Freightliner model. As expected, most of the changes made to the European model will be present on the 2014 Mercedes-Benz Sprinter when it goes on sale in the US, which is expected to be this fall.
The biggest difference between the Sprinter announced last week and the one headed to our shores is what is found under the hood. While European Sprinters will come with diesel engines and offer the availability of a supercharged four-cylinder gasoline or CNG engine, US Sprinters will still offer the 3.0-liter V6 BlueTEC diesel. This year's Sprinter now comes standard with a new base engine, the 2.1-liter four-cylinder BlueTEC diesel. This smaller engine will produce 161 horsepower and 265 pound-feet of torque, and will be paired to a seven-speed automatic transmission; the optional 3.0 V6 puts out 188 hp and 325 lb-ft of torque, and will be mated to a six-speed auto.
Fuel economy for the new Sprinter has not been announced, but Mercedes-Benz has made numerous changes with the goal of improving efficiency. To this end you'll find a new, low-friction rear axle and the optimization for the generator, fuel pump and power steering pump.
