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 takes VW Westfalia Camper idea upscale with new Marco Polo

Earlier this year, Mercedes-Benz revealed the new V-Class. Slotting in below the popular Sprinter, the new V-Class replaced both the Viano and Vito upon its debut at the Geneva Motor Show. But Mercedes isn't quite done with it just yet. At the upcoming Caravan Salon in Düsseldorf, Germany, Mercedes will reveal the Marco Polo - a versatile, stylish and decidedly contemporary take on the classic camper van.
Named after the famous Italian explorer, the Marco Polo was converted by Westfalia, an outfit which you might more closely associate with classic VW camper vans but which Daimler absorbed over a decade ago. Offering, according to the press release below, "a maximum of opportunities to be independent, free and spontaneous," the Marco Polo sleeps four thanks to the rear bench that electrically folds flat into a bed and the second berth under the pop-top. The flexible interior is decked out like you'd expect a modern Mercedes to be, with ambient LED lighting as well as wood, metal and piano black trim.
It's got an onboard kitchenette with two gas burners, a sink and fridge with a 10 gallons of fresh water and an even bigger waste tank. All that gear is shlepped around by a choice of four-cylinder turbodiesel engines ranging in output from 136 to 190 horsepower. The relatively compact form boasts a turning circle similar to a full-size sedan and a height designed to fit into most garages and car washes. All of which just might make us reconsider the appeal of traveling by camper van.

Mercedes-Benz releases stunning first images of 2014 S-Class

The all-new 2014 Mercedes-Benz S-Class, designated W222, is one of the most highly anticipated debuts of its model year. Every generation of the flagship sedan has broken new ground in technology and innovation for the entire industry, and the German automaker appears determined to raise the bar much further with its latest arrival as it promises to deliver "the best automobile in the world." Mercedes-Benz has just released nearly two dozen interior images of the new sedan, showing off style in design, craftsmanship in execution and pioneering advancements in technology.
Unlike all previous generations - the first S-Class officially arrived in 1972 - the 2014 model completely discards a traditional instrument cluster and replaces it with two high-resolution color displays in 8:3 format with a screen diagonal of 12.3 inches (the outgoing model's gauges were a mix of digital and analog). The left unit displays traditional analog gauges (digitally, of course) while the right unit is reserved for infotainment and comfort settings with the automaker's all-new mBrace2 - a cloud-based entertainment and information delivery system that is rolling out this year.
