F125! Research Vehicle

The environmentally responsible Mercedes-Benz is capable of handling any traffic with zero-emissions

With its powerful, wheel-mounted electric the Mercedes-Benz F 125! Research is a particularly dynamic demonstration of the “fascination and responsibility”. Thanks to generous performance reserves it effortlessly with any traffic – with no emissions whatsoever.

its electric drive system on highly advanced Mercedes-Benz cell technology, the F 125! particularly satisfying and sustained pleasure. The electric power for the is generated on board by a chemical between hydrogen and oxygen, or from the efficient recuperation of energy. The only emission from the chemical reaction is water vapour. Total range is at the same level as a diesel car. The high potential of the electric drive in the F 125! once again the versatility of the highly scalable, E-Drive system from

Intelligently conceived vehicle

In the new Mercedes-Benz research vehicle, the cell stack is centrally under the bonnet at the front, the compact electric motors are near the wheels in the front and axle areas. The composite reservoir in the area of the centre between the front seats and the assembly, has a capacity of around 7.5 and is ideally protected against the of accidents.

Metal Organic the hydrogen reservoir of the future

Organic Frameworks (MOFs) are solid bodies which of numerous, always identical components and can be very variably put on a modular basis. They are up of nodal points known as Building Units (SBUs). The elements between these points are formed by organic known as Linkers. This principle allows solid with extremely large surface areas, which in provides the basis for an enormous storage capacity.

High storage capacity low volume and great flexibility

“inner” surfaces of up to 10,000 sq. m. per – the current status of research – MOFs attractive for numerous they are suitable as gas cleaners for cells, for example, and also – as for the F125! – as a storage medium for in this case hydrogen. can be used as pressurised containers bar), but for a higher storage also as low temperature tanks at 77 K -196 degrees Celsius), considerably above the 20 K boiling of hydrogen. These attributes and the variability of the MOF’s shape an installation position suited to the requirements. This means future MOFs can be flexibly in the body structure. Key advantages of solution:

Less installation thanks to better adaptability more scope for packaging and room for the occupants.

The low installed is conducive to a low centre of gravity, a positive effect on handling and dynamics.

Full integration into the structure ensures the best crash and operating safety.

battery with a high density

The lithium-sulphur battery behind the rear seats has a capacity of 10 kWh. It can be inductively at “intelligent” charging stations, and the charging process can be monitored and using a smartphone. The principal of lithium-sulphur technology, whose in vehicles still requires research, is the high specific density of the cells. Compared to batteries this allows compact but highly efficient storage. When designing the F the developers worked on the assumption by the time of its introduction into production, this battery will be capable of energy up to 350 Wh per kg. This would represent a doubling of current performance. The potentials of this technology are the subject of basic research, and are difficult to assess at present.


All in all, the F 125! represents a important step towards the maturity of a fuel cell car in the luxury class. With research vehicle, Mercedes-Benz is completely new future ways to large and luxurious automobiles are marketable, environmentally friendly and compatible.

Touring saloon sports car genes

The use of four motors has a number of advantages in of driving dynamics. Mercedes-Benz has delivered an impressive demonstration of the potential residing in this design with the battery-electric SLS AMG super sports car, rear-end module was developed for the F 125. The new front axle provides a visionary outlook on the of electric drive systems the front axle. The chosen of the drive components allows weight distribution, and also – to active torque vectoring – the assignment of power to each wheel.

Apart from optimal traction at all times, the all-wheel drive with its yaw-damping improves handling at high speeds. During cornering, however, wheel-specific allows a metered increase in the yaw with an improved steering and less steering effort. drive configuration also highly efficient energy at each wheel, cross-wind avoidance of load-change responses and even more controllable when cornering, without the for ASR (acceleration skid control)

Ride comfort at the highest

110 years after the invention of the passenger car, the Mercedes of 1901, Mercedes-Benz is once presenting a trailblazing, visionary concept – this time in the of a sporty and comfortable touring with an emission-free F-CELL HYBRID system. The concept future technological trends, a vehicle architecture to suit.

The F is the first electric car to feature an air and continuous damper adjustment. The is an optimal balance between comfort, driving dynamics and use of The system also allows the suspension height to be adjusted as a of speed and vehicle status – to improve the aerodynamics at fast speeds.

Optimal traction and driving are ensured by active torque at the front and rear axles. The gears at the front and rear accelerate the vehicle comfortably and interruptions in tractive power, up to the top speed. One technical highlight of the system is special compensation of moments in the front axle, almost entirely eliminates and recuperation influences on the steering, and reduces pitching.
