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.

Meet Buster, this 1968 Porsche racecar transporter from Mercedes

If you're thinking about Porsche and Mercedes-Benz when it comes to motorsports, your first thought is probably on the two German brands battling on the track. However, for decades, whenever Porsche's factory team went to compete, a custom Mercedes was right along with them hauling the racecars. These days the truck lives in the Brumos Collection in Jacksonville, FL, and goes by the nickname Buster. However, its story goes back to 1968 when Porsche ordered two commercial vehicles from Mercedes and then handed them over to a Stuttgart-based outfitter for customization. The results were these racing transporters that hauled models like the 917 and 956 until the '80s. The other survived, too, with a place in Porsche's collection. Well-known racers in their own right, Brumos scooped up the transporter in 2003 and have kept driving it to vintage racing events. The interior now boasts the signatures of many of the great drivers from the era of this historic truck. Watch the video for the whole story on the Mercedes with a whole lot of Porsche inside.

Germany says nein to EU ban on new fossil-fuel cars from 2035

BERLIN (Reuters) - Germany's government will not agree to European Union plans to effectively ban the sale of new cars with combustion engines from 2035, Finance Minister Christian Lindner said on Tuesday. In its bid to cut planet-warming emissions by 55% by 2030 from 1990 levels, the European Commission has proposed a 100% reduction in CO2 emissions from new cars by 2035. That means it would be impossible to sell combustion engine cars from then. European Parliament lawmakers backed the proposals this month, before negotiations with EU countries on the final law take place. Speaking at an event hosted by Germany's BDI industry association, Lindner said there would continue to be niches for combustion engines so a ban was wrong and said the government would not agree to this European legislation. Lindner, a member of the pro-business Free Democrats, which shares power with the Social Democrats and Greens, said Germany would still be a leading market for electric vehicles.
