The designers at Honda’s advanced design studio in Pasadena decided to take advantage of the packaging flexibility afforded by a fuel cell powertrain and mounted it mid-ship driving the rear wheels. Using the vertical flow fuel stack mounted behind the driver and an electric motor between the rear wheels, the FC Sport is a three-seater in the style of the McLaren F1 where the driver sits in the middle of the car with the two passenger seats on either side and further back. The FC Sport is strictly a styling study right now, but we wouldn’t be surprised to see a fully functional version at some point.

By the middle of the next decade Mercedes-Benz wants its entire lineup to be able to operate entirely free of petroleum. The German giant is working on a variety of technologies that will help provide crude oil free transport such as battery electrics, fuel cells and highly efficient internal combustion engines that can operate on biofuels. Mercedes has recently been letting European journalists sample some of these new powertrains at a test facility in Spain.

The F700 concept that debuted last fall in Frankfurt is powered by a turbocharged DiesOtto engine. The DiesOtto is Mercedes’ branding for a combined HCCI and spark ignition engine that provides nearly the same efficiency as a diesel without the need for the expensive after-treatment systems. This and conventional diesel engines can run on biofuels and Mercedes hopes to launch the DiesOtto in production by 2010. Mercedes is also currently field testing electrically-driven vehicles with both batteries alone and fuel cells each of which they also plan to launch at the beginning of the decade. While it may well be that all Mercedes models in 2015 will be capable of running petroleum free, the reality is that many - if not most - will still be using fossil fuels much of the time. That may come in the form of coal for electricity, natural gas reformed into hydrogen, or petroleum fuels blended with biofuels. But you have to start somewhere.
