Mercedes-Benz has unveiled its F 125! research vehicle, which the company says is a concept showcasing what a large, luxurious automobile will look like in 2025.

The F-CELL plug-in hybrid has a range of 1,000 km, and features, among other things, the use of a revolutionary hydrogen storage technology, a lithium-sulphur high-voltage, high-energy battery as well as e4MATIC-all-wheel drive with four wheel electric motors and individual torque control at each wheel. The car also pioneers battery charging by induction.

The four-seater concept has a bodyshell of innovative, lightweight hybrid construction with a high proportion of fibre-reinforced plastics and a mix of carbon-fibre, aluminium and high-strength steels. A high-strength construction with crash-responsive protective systems within the doors allows the omission of B-pillars, and the car utilises wide gull-wing doors to offer easy access to the four seats.

The F 125!’s hydrogen tank is integrated into the floor assembly, and has a capacity of around 7.5 kg of hydrogen. Compared to the high-pressure tanks in use today, the tank here requires less installation space as opposed to current tanks, which need to be cylindrical in shape.

Meanwhile, the advanced lithium-sulphur battery envisaged for the F 125! has a storage capacity of 10 kWh and is installed behind the rear seats. Combining the fuel cell drive system with the innovative lithium-sulphur battery offers up to 1,000 km of travel, of which up to 50 km can be under battery-electric power alone. The battery can be inductively charged at “intelligent” charging stations, and the convenient charging process can be monitored by smartphone.

The fuel cell stack in the car provides the power for four powerful electric motors installed near the wheels – the modular e4MATIC system, which also uses improved drive components from the SLS AMG E-CELL, generates a continuous output of 231 hp and a peak output of 313 hp. It’s all good enough to propel the F 125! to 100 km/h in 4.9 seconds and a top speed of 220 km/h.

The interior features a control and display concept based on touch, speech and hand-gestures, making for a car which the driver is able to interact with – the gull-wing doors can also be opened and closed by hand-gestures.

Elsewhere, attractive displays using 3D and projector-beam technology are to be found, as are next-generation, substantially networked telematics that allow internet-based voice control, integration into social media and extensive remote control of vehicle settings and entertainment functions. Occupants will always be online and connected through an @yourCOMAND cloud-based infotainment system.

The car also features innovative assistance systems such as Advanced Driving Assist, which allows lane-changes on multi-lane, one-way roads, and in a further development stage will even offer automatic overtaking manoeuvres.
