Recharge Wrap-up: Porsche 911 hybrid possible, Ecocruise EVs coming soon

The next-generation Porsche 911 could use hybrid power, according to Porsche CEO Matthias Muller. "There is no reason against it and we will see if we have some reasons to do it," Muller says of the model due around 2018. He also suggests that hybrid technology could eventually make its way into all Porsche model lines, but that the Boxster and Cayman would first get four-cylinder versions. Muller cites carbon emissions and "sportiness" as reasons to use hybrid power, pointing to the 918 Spyder as a good example of both. Read more at Car Advice. A B-Class F-Cell from the Mercedes-Benz fleet has hit a benchmark of 300,000 kilometers (about 186,411 miles) in everyday use. The achievement won Daimler an "f-cell award" for hydrogen fuel cell technology and innovation. The 300+ fuel cell cars in the Daimler fleet have driven a collective 9 million-plus kilometers (more than 5.5 million miles). The information gathered from this testing is being used to improve development as the company looks toward expanding commercialization of fuel cell cars. "We have clearly demonstrated that the fuel cell electric drive is ready for the road," says Professor Herbert Kohler of Daimler. "The last hurdles we will overcome in intensive cross-industry and cross-border teamwork." Read more in the press release below. A company called Ecocruise has new EVs coming out soon. Along with electric scooters and service vehicles, Ecocruise develops street-legal neighborhood electric vehicles like the three-wheeled EZip-3, the four-wheeled EZip-4, and the fun looking Cruser Sport (see a prototype in the video below). The EVs are scheduled to go on sale in January of 2015, which is right around the corner. Ecocruise was started after the founder of Kasea Motorsports decided to switch to electric vehicles with the goal of offering providing affordable emissions-free driving. Learn more about Ecocruise and its vehicles at the company's website. The new EU Fuel Quality Directive (FQD) does little to discourage dirty fuels like tar sands and coal-to-liquid, says Transport & Environment (T&E). The FQD requires suppliers to reduce greenhouse gas intensity for transport fuel in the EU by six percent by 2020. The much-delayed FQD doesn't do as much as it could, though, say critics, and it doesn't label dirtier fuel sources as such despite the urging of scientists. T&E, an organization focused on cleaning up EU transport, blames Canada, the US and Big Oil.

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.
