The Mercedes-Benz F-125! Fuel Cell Plug-in Hybrid is designed to celebrate the company’s 125th anniversary, much like the Maybach Edition 125. The Mercedes-Benz F-125! concept model is designed to envision the future of Mercedes-Benz luxury cars. The Mercedes-Benz F-125! Fuel Cell Plug-in Hybrid has gullwing doors and runs on four-electric motors with energy draws from the hydrogen fuel cells. The combined output of four electric motors is about 231 horsepower. Mercedes-Benz claims that the F-125! concept can accelerate from 0-62 mph in merely 4.9 seconds and with a top speed of 137 mph. Not bad for a 231-hp powertrain. What is more amazing about F-125! concept is that it has a driving range of about 620 miles before refueling the 7.5-kg hydrogen fuel tank.
