Hybrid Modes

Parallel Mode
The gasoline engine works together with the electric motor to both provide power to the rear wheels. This depletes the battery pack over time.

Conventional Mode
The vehicle is entirely driven by the gasoline engine. The electric motor spins but does not add or take away torque from the drivetrain.

EV Mode
The electric motor provides all the propulsion for the vehicle. The engine is de-coupled from the drivetrain with the clutch so it does not waste any energy.

Regenerative Mode
The electric motor slows the vehicle down by reversing the torque direction during braking. The first part of the brake pedal travel of the Formula Hybrid vehicle is entirely devoted to regenerative braking; only after this point are the mechanical brakes engaged. Unfortunately this creates two distinct regions of brake pedal feel, but it allows the driver to very precisely control his power usage for the endurance event.
