Regenerative Braking

Another option is the Regen on Accelerator Pedal mode where regenerative braking is activated when the driver eases off the accelerator pedal. This system allows the vehicle to slow down and recover energy without the driver needing to press the brake pedal, a feature often referred to as one-pedal driving.

However, it is not considered full one-pedal driving since, at low speeds, the vehicle will keep rolling until it comes to a stop by itself.
