First Gear

First gear, also known as low gear, is the initial and most powerful gear in a vehicle's automatic transmission. It is designed to deliver maximum torque, which is essential for getting a vehicle moving from a standstill, especially on an incline. When you put your car in drive, the first gear speed is what propels the vehicle forward with the greatest force.

Driving in first gear is a common practice for overcoming the inertia of a stationary vehicle and is also useful for maneuvering at very slow speeds. It provides the initial burst of power needed to start the car's movement, with the transmission then shifting to higher gears as the vehicle's speed increases. This powerful first gear torque is fundamental to the operation of a car's transmission.
