What is b gear in hybrid?

In hybrid vehicles, the "B gear" or "engine braking" mode is a setting that is typically found in the transmission or drive mode selector. When the B gear is engaged, the electric motor and gasoline engine work together to slow down the vehicle. This process reduces the amount of wear and tear on the brakes, as the engine and electric motor generate resistance and help to slow the vehicle without the need for constant braking.

The B gear also provides a more aggressive regenerative braking characteristic to recapture more energy from the brakes. This excess energy can be used to charge the battery and enhance fuel efficiency. While the B gear may not be necessary for everyday driving, it can be useful for steep descents, slow-moving traffic, or when driving on slick roads.

In summary, the B gear in hybrid vehicles helps to improve braking performance, along with reducing wear and tear on the vehicle's brakes. It also enhances energy efficiency by using the electric motor to slow down the car and capture regenerative braking energy.
