The F-Cell Roadster Concept, built by 150 trainees working on the project for more than a year now, is the combination of state-of-the art technologies with the history of Daimler-Mercedes. So the car might look pretty historical from those large spoke wheels similar to those found on the 1886 Benz Patent Motor Car, but features some fairly modern touches like the SLR scissors doors.
Inside applies more of the "retro-futuristic" theorem. Where it might have a fully-wooden floor, the sporty leather bucket seats are made of carbon-fiber. The F-Cell Roadster Concept is also controlled with drive-by-wire technology, and a joystick takes the place of a conventional steering wheel.
However, concerning the drive-train, it's all highly-sophisticated future-generation technology, nothing to do with retro. F-Cell stands for fuel-cell, that is emission-free. So the fuel-cell is actually the engine, that has zero emissions. With a power rating of 1.2 kW the F-CELL Roadster Concept reaches a top speed of 25 km/h (15 mph) and has an operating range of up to 350 km (217 miles). So, it won't be rolling showrooms any time soon.
This was just a design study-case for the trainees to work them off a bit. But it shows what Mercedes is planning for the next 10 or even 20 years time.
