Mercedes-Benz F125

The Mercedes-Benz F125, written F 125! by the maker, is an electrically driven hydrogen fuel cell concept car unveiled at the 2011 Frankfurt Motor Show and named to mark the 125th anniversary of Mercedes-Benz. It is a five-metre two-door coupe with front gullwing doors that open onto both the front and rear seats. Each wheel has its own electric motor, giving a rear-biased four-wheel drive system called e4MATIC, with 50 kW at the front and 100 kW at the rear and a total peak of 230 kW. The motors draw on a 10 kWh lithium-sulfur battery mounted upright behind the rear seats, which a hydrogen fuel cell between the front wheels keeps supplied with energy. The maker claimed 4.9 seconds from rest to 100 km/h and a top speed of 220 km/h.
