Don't mind the zero-emissions Mercedes fuel-cell car behind the invisible curtain (eyes-on video)
Mercedes wanted to make a dramatic statement about how its new B-Class F-Cell car passes through the environment without leaving a trace, so it placed it behind an invisible LED curtain. We wanted to (not?) see that for ourselves at the Paris Auto Show, so took a quick tour of the magic LED cloak and the technology behind it. It doesn't work quite as well in a show hall as it did when we first saw it in its natural habitat, but the system was still a fun way to show off Merc's green ambitions. It works by passing video from behind the car taken with a Sony video camera through a laptop to a 200 x 300 resolution LED curtain. That makes the car blend in with its background, which is what such a car would do in the real world as far as its emissions go -- apart from a little water, of course. See the video below for the complete technical explanation.
Mercedes F-Cell World Drive gets off to an inauspicious start
Circling the globe on hydrogen power sounds like a bit of a challenge, what with the lack H2 pumps and all, but Mercedes-Benz set off to show that it could do just that -- with the help of a mobile filling station, natürlich. It's the F-Cell World Drive, and unfortunately, things got off to something of a bad start with two cars running out of fuel on the very first leg of the journey, one with Autoblog's Michael Harley at the wheel, no less. This first leg apparently began with a trip down an unrestricted bit of the Autobahn and, well, it seems the drivers of the cars decided to see what the little green B-Class F-Cells could do. The answer is 110mph, and of course moving along at this rate of speed did little for their range. The two cars came up 20km short of their first planned refueling stop, heavy right feet resulting in consumption of 1.5Kg of hydrogen per 100km distance -- roughly equivalent of 45mpg and way less than the 71mpg equivalent the cars usually manage. We're told day two, when drivers kept the speed to around 70mph, progressed much more smoothly, with both cars covering their expected legs without issue.
