Mercedes-Benz F125! gullwing fuel cell concept leaks ahead of Frankfurt

According to Omni Auto, the F 125! concept showcases M-B's design direction for the 2025 CL-Class. It's unknown if the German automaker intends to make a production CL that's fueled by hydrogen, but if the German automaker does, then Omni Auto says its likely that the setup featured in the F 125! that will be used. In this case, that means four electric motors cranking out a combined 231 horsepower. That level of grunt allows the F 125! to hit a top speed of 137 miles and zip from 0 to 100 km/h in 4.9 seconds. According to Omni Auto's leaked information, Benz says the F 125! consumes 0.79 kilograms of hydrogen per 100 kilometers and that the stylish coupe can travel up to 1000 km on a full tank.

As you can probably tell, the F 125! draws styling cues from the automaker's F800 Style concept, a four-door sedan that debuted at the 2010 Geneva Motor Show. However, the prototype F 125! features a chassis made from a mix of carbon fiber, aluminum and plastics along with a unique carbon fiber tank to hold hydrogen at 700 bar. The gullwing's 10-kWh lithium-ion battery pack allows the 125 F! to travel approximately 31 miles before activation of the on-board fuel cell is required.
