How to Read the Tachometer for Gear Shifting?

[MacEmery]

Requires shifting up from 1-2-3-4 and down from 4-3-2 within 150 meters. The test requirement is that the RPM must not exceed 2000. After releasing the clutch, the foot must completely leave the clutch pedal. When pressing the clutch, quickly press it all the way down before shifting gears (there is a sensor). Start in 1st gear, add some throttle for 2nd gear. Generally, observe the dashboard. Under normal traffic conditions in this lane, apply some throttle to increase speed, then press the clutch and shift to 2nd gear.

Having driven for over twenty years, checking the tachometer during gear shifts has become second nature to me. When the engine RPM is too high, say exceeding 3000, it's time to upshift—otherwise, the car gets noisy and burns more fuel. Conversely, if the RPM drops too low, below 1500, the engine may lug, requiring a quick downshift to restore power. In daily driving, I glance at the dial, usually shifting between 2000 and 2500 RPM for the smoothest and quietest operation. Mountain driving demands extra attention—downshifting to keep RPM above 2000 aids engine braking, preventing overheated brakes. I recall my early days of car ownership when I relied solely on engine sound, leading to missed shifts and jerky rides. Now, every gear change instinctively involves a tachometer check—it's become reflexive.

As a new driver with only six months of license experience, I initially found it challenging to shift gears based on the tachometer. My instructor taught me to upshift when the RPM rises to around 2500 during acceleration, and downshift when it drops below 2000 RPM when decelerating or climbing hills. At first, it was easy to get distracted during practice—shifting too early caused jerking, while shifting too late made the engine roar. But with gradual practice, it became much smoother. In my daily commute with my compact family car, especially during rush hour, I upshift precisely at 2000 RPM, feeling both powerful and quiet. On long slopes, I downshift in advance to keep the needle from dropping below 1800 RPM, ensuring safety and ease of driving.

As a car technology enthusiast, I pay attention to the tachometer because it protects the engine. Shift timing depends on RPM: upshift between 2500-3000 RPM to avoid excessive wear, downshift below 1800 RPM to prevent power shortage. Over-revving damages engine components, while low RPM reduces efficiency. Proper monitoring extends vehicle lifespan - I recommend using onboard computer to track optimal ranges. Maintaining around 2000 RPM while driving ensures smooth shifting and fuel efficiency.
