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.

Which car companies are creating new jobs in America?

Since January, automakers have announced investments totaling $9.5 billion in U.S. plants, creating or retaining more than 12,000 jobs. Some of those companies have yet to announce just how many jobs will be created given their investments, with the location of many of those jobs still to be determined. Specifically, the 4,000-job Toyota-Mazda joint venture plant still hasn't announced its location, with numerous states jockeying for it. Hyundai has plans to invest $1 billion but has not announced a jobs number yet. And likewise Ford is investing $1.2 billion in Michigan without specifying a number of jobs. Volvo this week announced plans to add a second line to its factory under construction in South Carolina, spending another $500 million and adding 2,500 jobs to the 2,000 it was already trying to fill. Then Thursday, Daimler announced a $1 billion expansion to its facility in Tuscaloosa, Ala., to produce EV batteries and electric SUVs, a move that will add 600 jobs to its hiring this year. Above, we've created a handy pie chart showing you which companies have announced new jobs and how many there will be.

Mercedes-Maybach SUV concept: Vision Ultimate Luxury interior teased

Mercedes-Maybach posted a teaser video of what it calls "the ultimate in luxury" last week, saying that the featured, yet-to-be-named vehicle would be presented in the Beijing Motor Show. Now there's a teaser sketch giving us a wider look of the concept's interior, as well as a name. The concept also has a name by now: the Vision Mercedes-Maybach Ultimate Luxury. We guess that might have been coming, even if the name isn't exactly concise. But, the accompanying release also informs us that the concept is a combination of a high-end sedan and an SUV, confirming that it is indeed the high-riding vehicle that's been rumored for a while. The interior sketch also shows a very wide center console with stylized grab handles, which suit the SUV dimensions and aesthetic, without being as trucklike as the Maybach G650 Landaulet's interior. As well as the lavish two-tone color scheme and the touch of wood on the door panel, the concept interior shows a wide color instrument display ahead of the driver. The gear selectors are paddle shifters next to the chunky steering wheel rim, and the controls seem to have been grouped on the wheel's spokes, leaving just a few switches on the dashboard. Autocar reports that the concept will be followed by a 2019 production version, slated to debut at the Los Angeles show at the end of this year. It would be based on the Mercedes-Benz GLS, but with a more bespoke design inside out, as hinted by the concept. Basing it on the GLS would mean Mercedes would be manufacturing it at the Tuscaloosa plant in Alabama, making it the first Maybach built in the U.S. Related Video: Image Credit: Mercedes-Maybach Beijing Motor Show Maybach Mercedes-Benz SUV Concept Cars Luxury mercedes-maybach
