Mercedes-Benz F 125 @ Mercedes-Benz S-Class @ 2025

The F 125! research vehicle demonstrates the future of emission-free individual mobility in the luxury segment.
Researchers and developers have also drawn on fledgling technologies which showed a great deal of promise at the basic research stage.

The F 125! research vehicle anticipates future trends and prepares the way for implementation of an innovative premium concept for large, luxurious automobiles. In the F 125! Mercedes-Benz rigorously follows its vision of emission-free driving with hydrogen power, underlining the potential of H2 as an energy source for the future. While previous Mercedes-Benz research vehicles have "looked ahead" by roughly one vehicle generation - seven to eight years - the F 125! as the latest technological visionary goes a whole step further, by more than two generations to the year 2025 and beyond.
The Mercedes-Benz F125! is an electrically driven, hydrogen fuel cell concept car unveiled at the 2011 Frankfurt Motor Show. It is named 125 to celebrate the 125th anniversary of Mercedes-Benz
The 197 in (5.00 m) long car has two Gull-wing doors and provides access to the four seats.
Powered by an electric motor at each wheel creating a rear-drive biased four-wheel drive "e4MATIC" system. The front motors provide 67 bhp (50 kW; 68 PS) and the rear 134 bhp (100 kW; 136 PS) with a total peak of 308 bhp (230 kW; 312 PS) electric motor, powered by a 10-kWh capacity lithium-sulfur battery located in a vertical position behind the rear seats. The batteries are provided energy by a hydrogen fuel cell located between the front wheels.
The F125 has a claimed acceleration time to 62mph in 4.9 seconds and a top speed of 220mph
The decisive innovations are:
A logical further development of the fuel cell drive system in combination with plug-in technology
Revolutionary tank technology: the structure integrated hydrogen composite storage unit.
Lighter and more powerful batteries, in this case based on lithium-sulphur technology, which Mercedes-Benz is examining in parallel with further development of the current lithium-ion battery and research into lithium-air technology.
On this basis the F 125! was created as an innovative four-seater luxury saloon with a powerful, emission-free electric drive system based on the fuel cell technology developed to series production maturity by Mercedes-Benz. This study combines pioneering and highly efficient storage, drive and bodyshell technologies with unique control and display concepts. The research vehicle also presents itself with an expressive design which transfers the classic Mercedes design idiom into the future.
Highlights of the F 125! :
Completely emission-free mobility with a range of up to 1000 kilometres, full day-to-day suitability, superior performance and first-class comfort.
A bodyshell of innovative, lightweight hybrid construction with a high proportion of fibre-reinforced plastics and an intelligent mix of carbon-fibre, aluminium and high-strength steels, which allows a significant weight reduction while offering a further considerable improvement in safety.
A high-voltage lithium-sulphur battery with a specific energy density of 350 Wh per kg at cell level, which allows considerably higher recuperation rates in combination with the e4MATIC all-wheel drive.
A control and display concept based on touch, speech and hand-gestures makes the F 125! a true "companion" with whom the driver is able to interact flexibly and effortlessly. The gull-wing doors of light-weight CRP construction can also be opened and closed by hand-gestures.
Highly attractive displays using 3D and projector-beam technology to open up new visual possibilities.
Next-generation, substantially networked telematics allow internet-based voice control, integration into social media and extensive remote control of vehicle settings and entertainment functions.
Innovative assistance systems for lasting driver stress relief, e.g. Advanced Driving Assist for semi-autonomous driving.
Trailblazing exterior and interior design based on a completely new saloon architecture.
