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 Vision Tokyo concept shows us our lazy future

The first autonomous vehicles to hit the road will likely look much the same as the ones we drive currently. But as self-driving technology evolves, so too will the shape of the vehicles themselves. And this is what Mercedes figures that future could look like. The Vision Tokyo concept, so named for the show now ongoing at which it's been unveiled this morning, is an odd yet forward-looking shape, rendered in Alubeam silver and glowing blue. Power comes from a hybrid hydrogen fuel cell and inductive electric charging system that give it a theoretical zero-emissions range of over 600 miles. One look at the lozenge-like shape should tell you that the design is all about the interior space. The driving station – should it be needed – offers a clean dashboard with HUD-only instruments and a central driving position with unobstructed view through the wraparound windscreen. The cabin is clearly focused, however, on the lounging occupants more than on the driver. Accessed via a single, giant gullwing hangar door, the approach is closer to that of a mobile lounge space than a traditional automotive interior, with a wraparound sofa, some manner of high-tech 3D game projected in the middle, and a wide infotainment screen on the inside of the door. The concept clearly foretells of a different future – one that demands less of the driver and offers more relaxed comfort. So while the driver within us grows concerned at his numbered days, the rest can't help but be strangely intrigued. Scope out the live images from the floor of the Tokyo Motor Show and share your thoughts on the concept in the Comments section below.

Mercedes A-Class next up for facelift

This is the coming Mercedes-Benz A-Class, and in case the paucity of camouflage didn't make it clear, it won't look much different the one that's been on sale for all of two years. Caught in Sweden braving the temperatures, its exterior updates aren't expected to go much further than a reworked face that brings it in line with the recently updated B-Class, including a new grille, headlights and taillights, and bumpers. The cabin is where most of the work is being done, to give it a better punch against the BMW 1 Series. A tweaked dash cluster, better fabrics and materials, the eight-inch tablet-style nav/multimedia screen, and ambient lighting should join the party. The updated range of B-Class engines should also make the jump into the A. A photo caught at a dealer meeting in Barcelona last year makes us pretty sure it will be introduced at the Frankfurt Motor Show in September this year. Until then, there are spy shots to peruse.
