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. Because Mercedes has managed to shrink the size of its F-Cell (fuel cell) componentry, the F800 can squeeze the fuel cell or plug-in hybrid powertrains into the engine compartment and (says Mercedes) the gaps within the chassis. And there’s still room inside for five.

The plug-in version of the F800 Style has a next-generation, direct-injection 299bhp 3.5-litre V6 petrol engine, mated to an 80kW hybrid module that’s integrated into the seven-speed gearbox. There's also a lithium-ion battery with over 10kWh of storage capacity, and the F800 can reach 75mph in electric mode – it manages 155mph with petrol power – and return 68g/km.

The all-electric version features a 100kW motor that develops 214lb ft and is powered by a hydrogen full cell and lithium-ion batteries. The technology is a development of the system found in the B-class F-Cell, though adapted for the F800’s rear-drive layout.

Merc promises we’ll see more of the both alternative powertrains in production cars soon. 'Characteristic features of the F800 Style are its innovations, whose development is already close to the series production stage,’ says Professer Herbert Kohler, Merc's chief environmental officer. ‘This is true not only of the electric drive with fuel cells but also of the Plug-in Hybrid, whose components were taken from our modular system for electric and hybrid vehicles.' Expect an S500 Plug-in Hybrid version of the next-gen S-class.
