When it comes to driving a car, sometimes we need to rely on our bottom gear - the gear providing the most torque and power in order to navigate steep inclines or rough terrain. However, there are a variety of different terms used to describe this gear, depending on the car and the region. Some call it the first gear, while others use the term low gear or granny gear. Off-roading enthusiasts may refer to it as the crawler gear, while truck drivers may use the term bulldog gear. Regardless of what you call it, having a reliable bottom gear is essential for safely navigating challenging driving conditions.
