Daimler chairman agrees with German Greens on reducing emissions

Daimler Chairman Dieter Zetsche spoke at a Green Party congress in Germany earlier this week and said he agreed with the party's urge to dramatically cut transportation-based greenhouse-gas emissions by expanding plug-in vehicle sales, Reuters says. Zetsche stopped short of backing the Greens' suggestion to ban gas- and diesel-powered vehicles by 2030, though. The man must keep his job, after all. Zetsche did say that reducing greenhouse-gas emissions from the transportation sector was "necessary," and his company has made plans to do just that. Daimler representatives said at the Paris Motor Show earlier this year that Smart and Mercedes-Benz both planned to debut more than 10 electric vehicles within the next decade, and that plug-ins may account for as much as 25 percent of Mercedes-Benz's sales by then. Moreover, Dr. Thomas Weber, Head of Group Research and Mercedes-Benz Cars Development, said in June that Mercedes could be selling as many as 100,000 EVs a year by the end of the decade. Last month, Mercedes-Benz announced that its EQ electric-SUV concept would go on sale by 2020, and that the Bremen factory that's producing the model will broaden its plug-in vehicle production further. Zetsche's cautious support notwithstanding, the German government appears to be doing its own part to reduce emissions from the country's light-duty vehicles. Earlier this year, Germany enacted a plan that provides as much as 4,000 euros ($4,270) in perks for people who buy new electric vehicles, with German automakers agreeing to foot about half of the estimated $1.4 billion bill. German lawmakers had also floated the idea of a 10-year moratorium on electric-vehicle taxes for cars purchased before 2020.

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.

Formula 1 seeking independent engine supplier

Formula 1 could get a new engine supplier in the near future, if Bernie Ecclestone and the independent teams gets their way. According to Autosport, the FIA is soon to open the contract up for bids, and there are already several manufacturers that have expressed interest. Currently Mercedes, Ferrari, Renault, and Honda supply engines – both to their own premier teams (Red Bull and McLaren for the latter two) but also to other teams like Williams, Sauber, and Toro Rosso. Because the new turbocharged V6 hybrid power units cost those four suppliers so much to develop, they're charging their customer teams big bucks – around $20-30 million per season – to provide the engines. These costs are much higher than the $10 million or so it used to cost to purchase a V8 engine under the previous regulations. Ecclestone figures it's time to bring in another supplier who will not run their own team and not play favorites, but will supply engines to private teams at a lower cost. There are already a number of potential suppliers under consideration. One of them is said to be Cosworth, which has a long history in the series stretching back to 1963. The British firm stepped back between 2007 and 2009, returned in 2010, and dropped out again after 2013. The development could be of particular benefit to Red Bull, which has been unable to find an engine supplier and could be forced out of the series as a result. The team has long been powered by Renault, but that relationship has grown sour. And the other three engine manufacturers have not been forthcoming in offering an alternative arrangement for the team.
