Mercedes-Benz F 125! research vehicle
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.

Innovative ideas reaffirm the claim to leadership in the luxury segment

A high-strength construction with crash-responsive protective systems within the doors allows the omission of B-pillars, as well as the use of wide gull-wing doors.
The F 125! demonstrates how completely emission-free, individual mobility might be realised in the luxury segment in the future. The researchers and developers at Mercedes-Benz have incorporated already well-proven concepts and technologies which are not yet available today, but for which basic research has shown great future promise, and therefore a realistic chance of implementation in future series-production cars.
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.

A retractable 17-inch display is installed on the front passenger side, and this is fully controlled by hand gestures. In this way a rear passenger can select his personal film programme with no physical contact.
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.
