Mercedes F800 Style concept (2010) first pictures

This is the new Mercedes F800 Style, a stunning concept car that the Germany company will unveil at the 2010 Geneva motor show next month. The exterior previews the next CLS (and Mercedes’ future design language) while under the skin there’s all sorts of clever tech, from the next generation of HMI control systems to plug-in and fuel-cell powertrains. Mercedes calls it a ‘multi-drive platform’, and the F800 Style is built to take both hydrogen fuel-cell and plug-in hybrid powertrains, with the former offering a range of 375 miles and the latter allowing for 19 zero-emissions miles.
