Why Use First Gear for Starting?
2 Answers
Starting a car in first gear allows the clutch to operate in its optimal state. This is because first gear provides the highest torque, which is ideal for moving a stationary vehicle. Below are some relevant introductions about car starting: Precautions for Car Starting: On special road surfaces such as icy, snowy, or muddy slippery roads, second gear can be used for starting. This prevents excessive torque from causing wheel spin, which could make the wheels sink deeper. Second gear starting, with its relatively lower torque, is suitable when the car does not require or should not use too much torque to transition from a stationary to a moving state. Car Starting Method: Depress the clutch fully, engage first gear, pause for one second at the half-clutch point, and then apply the throttle. This achieves the best state of semi-engagement and quick acceleration, thereby protecting the clutch's lifespan.
I remember when I first started driving, I always found it troublesome to use first gear for starting. After driving for a while, I realized that first gear has the largest gear ratio, which amplifies the engine's power to easily propel the wheels, especially when going uphill or carrying heavy loads. If you start directly in a higher gear, the car often shakes or even stalls. Back when I was a novice, I got scolded by my instructor for this. In city driving with frequent stops and starts, using first gear not only ensures a smooth and fuel-efficient ride but also reduces engine stress, maintaining stable performance. On slippery winter roads, first gear provides more traction, preventing wheel spin and making driving safer. From an economic perspective, first gear efficiently converts energy, saving a bit on fuel right from the start, which adds up significantly over daily use.
