Daimler boss says fuel cell vehicles will be disappointing for at least 10 years

Daimler AG CEO Dieter Zetsche is pretty confident about the imminence of self-driving cars. Hydrogen fuel-cell vehicles? Not so much. He didn't even get into the possibility of self-driving fuel-cell vehicles, but we're okay taking future technologies one at a time. Zetsche, in an interview from the Detroit Auto Show last week, said the automotive industry is about a decade away from avoiding disappointing experiences with production fuel-cell vehicles, In Auto News says. Zetsche was quick to note that the Mercedes-Benz parent entered into a fuel-cell partnership with Ford and Nissan early last year in an effort to split costs and speed things along, with the expectation that the group would develop something together by 2017, but even that won't be able to smooth things out fully. Toyota and Hyundai have said they'd have their own production vehicles on the road sooner than that. Multi-corporation-partnerships notwithstanding, Zetsche bemoaned the high costs, lack of vehicle volume and minimal refueling infrastructure as the proverbial roadblocks to more rapid development and adoption of fuel-cell vehicles. As it is, the US has just 10 publicly accessible hydrogen refueling stations, eight of which are in Southern California, according to the US Department of Energy. As for autonomous automobiles, Zetsche was more upbeat. Daimler already has what it calls the "Distronic" cruise control system that includes an automatic braking feature and has successfully driven a car 60 miles with "with relatively modest adjustments to the existing onboard technology."

New Die Hard movie wrecked 132 cars in $11 million chase scene [w/video]

It would seem the act of dying hard brings with it lots of wanton destruction of the four-wheeled kind. According to John Moore, director of A Good Day To Die Hard, starring Bruce Willis, There were 132 (cars) that could never be used again. Another 518 required a lot of work. And damn right there were some good cars there... That's the fun of it."
Please join us in one great big collective sigh. Done? Okay, let's continue.
"With Die Hard it's about how audacious the action is," says Moore. "So you have to drive over a Lamborghini. An actual one. And yes it hurts me. I'm a car fanatic." Yeah. Sounds like it hurt really bad... though not as bad as the final tally after all the carnage had been counted: "Someone showed me the numbers on the car chase and soup to nuts, you put it all together it was like an $11 million sequence."

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.
