After few leaked photos, the Mercedes-Benz F125 Concept was unveiled today at the 2011 Frankfurt Motor Show, marking firm’s 125th anniversary. As we told you yesterday, the F125 Concept is powered by four electric motors installed near the wheels, capable to deliver a continuous output of 170 kW (231 hp) and a peak output of 230 kW (313 hp).
This enables the F125 Concept to sprint from 0 to 100 km/h (62 mph) in 4.9 seconds and has a top speed of 220 km/h.
Despite the impressive performances, the car needs only 0.79 kilograms of hydrogen per 100 kilometres (= 2.7 litres diesel equivalent). Regarding the range of the car, Mercedes-Benz says that the F125 Concept can travel up to 1000 km, but only 50 km can be under battery-electric power.
The F125 Concept has a fuel tank integrated into the floor assembly, which has a capacity of around 7.5 kg of hydrogen. This means less installation space, and more space for the passengers. What is more interesting is that the concept uses an advanced lithium-sulphur battery, which has a storage capacity of 10 kWh and is installed behind the rear seats.
Luxury cars aren’t typically seen as green, zero emission individual automotive options, but the Mercedes Benz F125! shows it is possible. The Mercedes-Benz research and development team implemented innovative concepts and systems that have yet to become available but have been shown to work. Preliminary tests promise a great future based on these technologies, which seem easily adaptable for tomorrow’s production automobiles.
These innovations include:
- The logical next step in fuel cell drive technology development, combined with the plug-in technology.
- All new more lightweight and powerful lithium-sulphur batteries developed by Mercedes-Benz in conjunction with further advancement of lithium-ion technology and development of lithium-air batteries.
- Ground-breaking tank technology featuring the structure integrated hydrogen composite storage unit.
From these underlying technological concepts, the Mercedes-Benz F125! was designed as an ultramodern four-seat premium saloon powered by a potent, zero-emission electric drive system derived from the company’s fuel cell technology developed for production levels. This project makes use of super-efficient, cutting-edge storage, drive and body shell construction along with exclusive display and control systems. Design-wise, the vehicle also adapts the well-known Mercedes aesthetic in an expressively futuristic manner. With regards to its performance and abilities, the standout features are:
- Absolutely zero emissions with a maximum range of 1000 km, providing daily reliability, top notch performance and premium-grade comfort.
- A body shell constructed from a hybrid of advanced, lightweight materials, including extensive use of fibre-reinforced plastics and an optimised combination of high-strength steel, aluminium and carbon fibre for excellent weight reduction and enhanced safety.
- Robust door construction with crash-responsive protective systems that eliminate the need for B pillars and utilise wide gull wing doors to facilitate easier access to all four seats.
- These construction design principles represent the Mercedes Benz safety commitment as illustrated by the adaptation of the rigid passenger cell concept originally developed in 1952 by Béla Barényi that continues to be improved for future automobiles.
- A powerful lithium-sulphur battery boasting a 350Wh/kg specific energy density at cell level, allowing significantly higher recuperation rates as it works with e4MATIC all-wheel drive system.
