It is named to celebrate the th anniversary of Mercedes-Benz. Powered by an electric motor at each wheel creating a rear-drive biased four-wheel drive "e4MATIC" system. The batteries are provided energy by a hydrogen fuel cell located between the front wheels. The first generation W was introduced in , the second generation model W appeared in late and the third generation model W was launched in

Most of its technologies are still under development. They call it the F After all, it was the Benz Patentwagen that came first. It suggests that the pace of evolution will be brisk: The F is an electrically driven, hydrogen-fuel-cell—powered, full-size luxury sedan with the range of a diesel, and it is just two model cycles away from the current S-class.

The light is artificial; there are no windows. More stunningly, it opens via two giant gullwing doors. Entry into the front and rear is as easy as falling into a recliner—it ought to be; there are no B-pillars in the way. At first glance, the car looks like a coupe, or at least a hatchback. But the overall envelope, with its low greenhouse, fast roofline, and crouched stance, suggests that the S-class, long the staid burgher of the luxury-sedan world, is about to get seriously sleek.

The biggest change may be that, after more than a century, the classic framed grille disappears, replaced by six gill-like slats topped with chrome bars. The interior seats only four. Its driver-oriented cockpit includes 3-D displays, a cloud-based telematics system, and an asymmetrical rear-seating concept. The driver gets his toys, too: Besides voice-controlled systems navigation, e-mail, internet access , other functions are triggered by hand gestures.

Swiping a hand quickly to the right turns on the wipers; pointing a thumb to the right engages the right-hand turn signal; and lifting a hand horizontally raises the temperature. Even so, outputs denote a rear-wheel bias: The front motors are capable of 67 horsepower and 55 pound-feet of torque apiece, while each rear motor is rated at horses and pound-feet.

Peak horsepower is ; continuous output is An advanced lithium-sulfur battery is packaged vertically behind the rear seats.

With a kWh capacity and an energy density of Watt-hours per pound, this battery beats current lithium-ion mass efficiency by a factor of two. But instead of storing the hydrogen for the fuel cell as a cryogenic liquid or as a high-pressure gas, it contains the hydrogen within a metal-organic framework MOF material.

This highly porous crystalline substance has more than 24 million square feet of surface area per pound. Mercedes says the F will consume hydrogen at a rate of 2. That, apparently, is what the next 13 years are for. Thanks to its reduced weight and linear power delivery, the series-production F will need only 4.

This could get expensive.

Mercedes-Benz F125 Concept

The F ! In the F ! 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. 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 F !
