Mercedes-Benz F 125! Hydrogen Fuel Cell Concept 2011 E4Matic 313 cv 220 kmh 0-100 kmh 4,9 s

(from Mercedes-Benz Press Release) As a highlight marking 125 years of the automobile, Mercedes-Benz is presenting a visionary outlook on future technical developments in the luxury segment. The Mercedes-Benz F125! research vehicle anticipates future trends and prepares the way for implementation of an innovative premium concept for large, luxurious automobiles.
In the F125! 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 F125! as the latest technological visionary goes a whole step further, by more than two generations to the year 2025 and beyond.
"With the F125! we want to show that large, comfortable and safe saloon cars have an excellent future, partly because they are able to operate with no emissions. The legend that is the S-Class will continue into the future thanks to intelligent solutions that always have the customer's needs in mind," says Prof. Dr. Thomas Weber, member of the Board of Management of Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. "The new research vehicle illustrates and underlines this claim to leadership with innovative ideas and traditional Mercedes strengths in the areas of design, safety, comfort and performance."
Innovative ideas reaffirm the claim to leadership in the luxury segment
The Mercedes-Benz F125! 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.
On this basis the Mercedes-Benz F125! 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 F125!:
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-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 which allow convenient access to the four seats. In this way the Mercedes-Benz safety philosophy and in particular the decisive principle of the rigid passenger cell developed by Béla Barényi in 1952 are being concertedly taken forward for the future of individual mobility.
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 Mercedes-Benz F125! 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.
