Here’s what the company said: The Fisker Ocean brake system uses both friction braking and regenerative braking. In December 2023, Fisker responded to customer feedback and issued an Over-the ...

Through its Kinetic Energy Recovery System (KERS) this race car is able to capture energy that's usually lost to braking heat, and store that energy in a flywheel system for later use. Under ...
