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.

2016 Mercedes-AMG GLE63 S Coupe 4Matic brings big power to go with massive name

Mercedes-Benz hopped into the luxury crossover coupe market with both feet with the recently debuted GLE-Class Coupe. While the existence of beauty in this segment is still up for debate, the Merc really gives the BMW X6 a direct competitor. With the newly unveiled 2016 Mercedes-AMG GLE63 S Coupe 4Matic, the engineers from Affalterbach are now also turning their sights on their rivals from BMW's M division. Don't let the name fool you. The GLE63 AMG Coupe eschews the twin-turbo 4.0-liter V8 from the C63 AMG in favor of an even bigger power source. This crossover uses the company's thundering 5.5-liter twin-turbocharged V8 with stop/start that pumps out 577 horsepower and 561 pound-feet of torque – 10 hp and 8 lb-ft more than the X6 M. The deep well of muscle means the sprint to 62 miles per hour takes just 4.2 seconds; faster than you can say the coupe's mile-long official name. The AMG Speedshift Plus 7G-Tronic seven-speed automatic gearbox routes all of that grunt to all four wheels with a 40:60 front/rear split. The styling of this beast gets a special nod from AMG by being the first CUV from the company to get its A-wing grille. Even if the rest of the design can be polarizing, this portion looks fantastic. The airfoil in the bumper is supposed to look like a stylized A, and from some angles, the wing almost appears like its just floating there. Each side of the GLE63 features black wheel arch flares, and around back there's a small lip spoiler on the tailgate. It's complimented by a new rear apron that has air outlets at each corner, integrated tailpipes and a diffuser in the center. Being a Mercedes-AMG, buyers sit in the lap of luxury inside. The seats are covered in Nappa leather with AMG crests on the headrests. The performance brand's moniker can also be found on the three-spoke steering wheel, and the instrument panel even gets covered in black Nappa. Obviously, if this isn't enough for potential buyers, Mercedes has a ton of options on hand. They include performance-oriented items like a sport exhaust system, 22-inch wheels and carbon fiber engine cover, but there're also more opulent choices like the fragrance mister and a high-end Bang & Olufson sound system. Scroll down for all the details on the much more powerful GLE Coupe. The new Mercedes-AMG GLE63 S Coupe 4MATIC Driving performance reinterpreted Affalterbach/Detroit.

Recharge Wrap-up: Daimler spending big for fuel cells, Ford Go!Drive experiment advances

Ford's Go!Drive experiment is entering its beta phase in London. The project, which is one of the automaker's global smart mobility experiments, uses a mobile app for on-demand carsharing of Ford Focus Electric and Ford Fiesta vehicles. The beta phase involves increasing the number of available vehicles from 20 to 50, and collecting new data from users. The program offers one-way rentals and guaranteed parking, with no membership fees and a cost of 26 cents per minute. Ford hopes to get 2,000 drivers involved in the program.

The company expects cost savings "in the range of hundreds of millions of euros until 2020," while maintaining its workforce of 18,700 employees and adding 150 vocational training positions. The upgrades will allow the plant to become a center for building more efficient engines, hybrid powertrains and fuel cell systems. "Alternative drive systems are an important element of our future mobility," says Mercedes-Benz's Markus Schafer. "Their share of automotive production is set to steadily rise over the next few years, complementing our highly efficient engines within the portfolio. This is what we have laid the groundwork for today." Read more at Reuters, or in the press release below. The Department of Energy is providing $20 million in funding for the development of more efficient high speed industrial motors and drives. Ditching old motors and gearboxes for ones that use integrated power electronics could help decrease the energy consumption of the industrial sector, which currently uses more than 25 percent of the electricity generated in the US. The projects being funded will reduce losses and decrease the size of drive systems used in industries like petroleum refining and natural gas, which could affect the lifecycle efficiency of transportation fuels.
