Mercedes-Benz’ F800 Style research vehicle is showing the future of premium automobiles from a new perspective, as the five-seat premium sedan combines highly efficient drive technologies with unparalleled safety and convenience features and an emotive design idiom, which interprets current Mercedes-Benz styling in line with the brand’s hallmark attribute of refined performance.
The F800 Style has a spacious interior full of intelligent seating, operating, and display concepts. Another unique feature of the large sedan is an all-new multi drive platform, which accommodates electric drives with fuel cells (enabling ranges of almost 375 miles) as well as the use of Plug-in Hybrids that can drive for up to 18 miles solely on electricity. Both variants of the F800 Style therefore make locally emission-free mobility possible at the level of a premium-class automobile, while at the same time being fully suited for everyday driving and providing a dynamic driving experience.

F800 Style with Plug-in Hybrid
In combination with the very powerful Plug-in Hybrid drive system, the F800 Style is a very dynamic expression of the concept of “fascination and responsibility.” Its drive unit consists of a V6 gasoline engine with an output of 300 hp with next-generation direct injection and a hybrid module with an output 109 hp so that it delivers a total power of around 409 hp. The lithium-ion battery with a storage capacity of >10 kWh can be recharged either at a charging station or a household power socket.
Due to its efficient drive system and a CO2 bonus for the battery-electric driving mode, the vehicle has a certified fuel consumption of only 2.9 liters of gasoline per 100 kilometers. This corresponds to extremely low CO2 emissions of only 68 grams per kilometer. However, thanks to its outstanding efficiency, the F800 Style equipped with a Plug-in Hybrid nevertheless has a driving performance comparable to a sports car (0-60 mph 4.7 s, top speed of 155 mph). When in electric mode, the F800 Style has a top speed of 75 mph, thus meeting the needs associated with long-distance driving.
Like the Mercedes-Benz S400 HYBRID introduced in the summer of 2009 and the Vision S500 Plug-in Hybrid, the powerful electric module (approx. 80 kW) of the F800 Style is completely integrated into the housing of the seven-speed transmission. The lithium-ion battery in the new research vehicle is located underneath the rear seat, where it takes up little space, creates a low center of gravity, and ensures maximum safety in the event of a crash.
The electric drive components in the F800 Style with the Plug-in Hybrid once again demonstrate the versatility of Mercedes-Benz’ extensively scalable modular hybrid system. The hybrid system 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 gasoline and diesel engines. Examples range from the current mild hybrids all the way to Plug-in Hybrids that enable pure electric driving over long distances. In developing the F800 Style with Plug-in Hybrid, the Mercedes engineers specifically focused on improving the pure electric driving in urban traffic. Thanks to high power reserves, the F800 Style in e-mode easily masters all kinds of city traffic while producing no local emissions. With the new hybrid module, the top speed of the F800 Style with Plug-in Hybrid has been increased to 75 mph in electric mode compared to the Vision S500 Plug-in Hybrid. At the same time, it emits only 68 grams of CO2 per kilometer, compared to the latter vehicle’s 74 grams per kilometer.
The F800 Style with electric drive and fuel cell technology
The F800 Style also offers clean driving pleasure in the variant equipped with an electric drive based on fuel cell technology. The vehicle’s electric motor develops around 136 hp as well as a strong torque of approximately 214 lb-ft. The fuel cell generates the traction current by chemically reacting hydrogen with oxygen onboard the vehicle, producing water vapor in the process as the only emission.
The new Mercedes-Benz research vehicle has the fuel cell located in the front, while the compact electric motor is installed near the rear axle. The lithium-ion battery is located behind the rear seats and is protected as well as possible against the effects of accidents, as are the four hydrogen tanks. Two of the tanks are located in the transmission tunnel between the passengers, while the other two are underneath the rear seat.
F800 Style with further innovations for more comfort and safety
In addition to a multi-drive platform that is unparalleled for large sedans and the combination of different alternative drive technologies, the F800 Style features many other technological innovations, such as a new multi-function display concept and a human-machine interface (HMI) with a cam touchpad. The display shows many additional functions not typically found in conventional instrument clusters. The F800 Style’s display concept focuses for the first time primarily on electric driving functions.[wzslider height=”400″ lightbox=”true”]
