F 800 Style

Efficiency paired with elegance: pioneering executive saloon with “green” technology and avantgarde designMercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicle

  • A new take on the “fascination and responsibility” concept
  • Multi-drive platform for plug-in hybrid or fuel cell
  • Generously sized interior for five people and compact exterior dimensions
  • Intelligent display concept with focus on “electric driving”
  • HMI with cam touchpad for intuitive and reliable control
  • Traffic Jam Assist function for enhanced convenience and safety

Mercedes-Benz presented the F 800 Style research vehicle at the 2010 Geneva Motor Show. The F 800 Style research vehicle shows the future of premium cars from a new perspective: the one-off five-seater executive saloon combines efficient drive technologies with unparalleled safety and convenience features as well as an emotive design idiom, which interprets current Mercedes-Benz styling in line with the brand’s hallmark attribute of refined sportiness. With an exterior length of 4.75 metres, the F 800 Style offers a generously-sized interior incorporating intelligent seating, control and display concepts. Another world-first for large saloons is the all-new, exceptionally flexible multi-drive platform, which is suitable for electric drive with fuel cells, enabling a range of almost 600 kilometres, as well as for a plug-in hybrid that can drive for up to 30 kilometres solely on electricity. Both variants of the F 800 Style make locally emission-free mobility possible for a premium car, while at the same time being ideal for everyday driving and providing a dynamic driving experience.Mercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicle

“We are dedicated to reconciling our responsibility for the environment with practical customer benefit in an exciting car,” says Dr Thomas Weber, the Daimler Board of Management member responsible for Group Research and Mercedes-Benz Cars Development. “The new F 800 Style research vehicle combines this commitment to providing the leading innovative drive concepts with our traditional Mercedes strengths in the areas of design, safety, comfort and outstanding performance.”

Within the compact 4.75-metre long exterior of the F 800 Style, all of the components of the vehicle’s exceptionally efficient and environmentally compatible alternative drive systems (plug-in hybrid or fuel-cell drive system) are installed in the engine compartment and in the gaps within the chassis to save space. Each of the drive systems takes up comparatively little space. This applies in particular to the electric drive with fuel cells, which has been enhanced by Mercedes-Benz to be compact and powerful. The front end’s compact package was made possible by the consistent downsizing of all F-CELL components. As a result, the entire interior space is preserved and offers plenty of room for five occupants.Mercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicle“For many decades now, our research vehicles have been turning pioneering concepts into reality and thereby setting future trends. We set a course in the large touring saloon segment in 2007, when we unveiled the F 700,” says Professor Herbert Kohler, Head of E-Drive & Future Mobility and Chief Environmental Officer at Daimler. “Characteristic features of the F 800 Style include innovations whose development is already close to the series production stage. 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.”

F 800 Style with plug-in hybrid:  outstanding performance and CO2 emissions of 68 grams per kilometreMercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicle

In combination with the powerful plug-in hybrid drive system, the F 800 Style is a dynamic expression of the “fascination and responsibility” concept. Its drive unit consists of a V6 petrol engine developing around 200 kW (272 hp) with next-generation direct injection, a hybrid module developing around 80 kW (109 hp) and a lithium-ion battery which can be recharged either at a charging station or a household power socket. Thanks to its powerful and high-torque hybrid module, in the city the F 800 Style can run exclusively on electricity and therefore without generating any local emissions. Because it also provides high torque right from the moment it starts, the vehicle delivers the same level of performance as a car with a V6 petrol engine even when operating in electric mode. The F 800 Style with plug-in hybrid can run purely on electricity for up to 30 km (19 miles). The F 800 Style research vehicle therefore marks a further important step in the development of a market-ready plug-in hybrid. Mercedes‑Benz will begin series production of this technology when the next-generation S-Class is introduced.Mercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicleThanks to its efficient drive system and a CO2 bonus for its battery-electric driving mode, the vehicle has a certified fuel consumption of 2.9 l/100 km (81.10 mpg/US, 34.48 km/l) of petrol , equivalent to low CO2emissions of 68 grams per kilometre – six grams per kilometre lower than the Vision S 500 Plug-in HYBRID. Yet the F 800 Style with plug-in hybrid still delivers performance on a par with a sports car (0-100 km/h in 4.8 s, top speed of 250 km/h/155 mph). When driven in electric mode, the F 800 Style has a top speed of 120 km/h/75 mph, and can thus also meet practically every requirement associated with long-distance driving.

As is the case with the Mercedes-Benz S 400 HYBRID introduced in the summer of 2009 and the Vision S 500 Plug-in HYBRID, the powerful electric module with an output of around 80 kW (109 hp)in the F 800 Style is integrated in the housing of the 7G-TRONIC seven-speed automatic transmission. The lithium-ion battery in the new research vehicle is located underneath the rear seat bench, where it takes up little space, creates a low centre of gravity and ensures maximum safety in the event of a crash.Mercedes-Benz F 800 Style research HYBRID Fuel-Cell vehicleThe electric drive components in the F 800 Style with plug-in hybrid once again demonstrate the versatility of Mercedes-Benz’s modular hybrid system, which can be expanded in various ways, depending on performance needs and the area of application. On this basis, it is possible to combine hybrid modules and batteries of different performance ratings with fuel-efficient, high-torque petrol and diesel engines. Examples range from the current mild hybrids all the way to plug-in hybrids that enable exclusively electric driving over long distances. When developing the F 800 Style with plug-in hybrid, the Mercedes engineers particularly focused on improving the possibilities of driving exclusively with electricity in urban traffic. As a result, the F 800 Style offers even higher power reserves in e-mode than the Vision S 500 Plug-in HYBRID. The F 800 Style can therefore easily master all kinds of city traffic while producing no local emissions. With the powerful hybrid module, the top speed of the F 800 Style with plug-in hybrid has been increased from 75 km/h to 120 km/h (47 to 75 mph) in electric mode compared to the Vision S 500 Plug-in HYBRID. Furthermore, it emits 68 grams of CO2 per kilometre, compared to the latter vehicle’s 74 grams per kilometre.
