Mercedes-Benz F 800 StyleFebruary 22, 2010
The F 800 Style is a concept for a Plug-in Hybrid luxury car with CO2 emissions of 68 g/km, or it can also be powered by a fuel cell.
In Plug-in Hybrid drive form, it comes with a V6 petrol engine with an output of 300 hp and a hybrid module with an output of 109 hp, giving a total power output of 409 hp.
The lithium-ion battery can be recharged either at a charging station or a household power socket and the F 800 Style can run exclusively on electricity and therefore without generating any local emissions.
Mercedes claims that the car has the same driving performance as a car with a V6 petrol engine even when operating in electric mode, due to the torque of the system. It can also manage 0-62 mph in 4.8 seconds and a top speed of 150 mph.
When in electric mode, the F 800 Style can run purely on electricity for around 20 miles and has a top speed of around 75 mph.
Mercedes-Benz will begin series production of the S 500 Plug-in Hybrid with the introduction of the next-generation S-Class.
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 electric module of the F 800 Style is completely integrated into the housing of the 7G-TRONIC 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 centre of gravity, and ensures maximum safety in the event of a crash.
The hybrid system can be expanded in various ways, depending on performance needs – it’s possible to combine hybrid modules and batteries of different performance ratings with fuel-efficient, high-torque petrol and diesel engines, ranging from mild hybrids to Plug-in Hybrids.
The F 800 Style also comes as a variant equipped with an electric drive based on fuel cell technology. The vehicle’s electric motor develops around 136 hp as well as strong torque of around 290 Nm. The fuel cell chemically reacts hydrogen with oxygen onboard the vehicle, producing water vapour in the process as the only emission.
The components of the fuel cell drive are taken from the range of e-drive modules, which Mercedes-Benz has developed for a variety of different electric vehicles. These components are already being installed in the limited edition B-Class F-CELL. The F 800 Style has rear-wheel drive, in contrast to the B-Class F-CELL. The same components are also installed in commercial vehicles, such as the new Citaro fuel cell bus, which is equipped with two of the F-CELL systems used in passenger cars.
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 against 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.
All of the components of the F 800 Style’s alternative drives (Plug-in Hybrid or fuel cell drive system) are installed in space-saving ways in the engine compartment and the gaps within the chassis. Each of the drive systems takes up comparatively little space for the installation. This applies in particular to the electric drive with fuel cell. All fuel cell components have been downsized; as a result, the entire interior space is preserved and offers room for five occupants.
Other technology in the F 800 Style includes a map that shows the remaining possible travel radius during electric vehicle operation as a 360° depiction, and at speeds of up to about 40 km/h, a Traffic Jam Assistant function can drive the car for the driver.
