Mercedes F125 Concept
The F125! Concept is designed to give the rich and powerful of the mid-2020s an advance look at what their big Mercedes-Benz sedan will be. Skipping not one but two generations forward along the hypothetical S-Class timeline, the F125! is powered by an unconventional plug-in hybrid powertrain: when the power the car sucked from an outlet runs out, a hydrogen fuel cell kicks on to generate power. Hydrogen is stored in a tank integrated into the body as a structural component, a feat not feasible today but something Mercedes-Benz claims will be possible in 2025.
