What is the standard for matching engine speed with gear?

[LaGiselle]

The standard for matching engine speed with gear is approximately 1000-1500 RPM at 10 km/h, suitable for shifting to second gear. When the speed reaches 30 km/h, it's appropriate to shift to third gear. At 40 km/h, shifting to fourth gear is recommended. When the engine speed is around 2500-3000 RPM, shift to fifth gear. Driving Modes: Launch Mode: Maintain the engine speed at around 4000 RPM. At this point, the torque output is at its maximum. When the clutch is released, the car will launch with the strongest burst of power, and the drive wheels may slightly spin. However, if the throttle is well-controlled, idling can be minimized as much as possible. Cornering Mode: If the throttle is opened too wide during a turn, high-powered rear-wheel-drive cars may experience tailspin or even spin out, so the speed should not be too high, depending on the horsepower. For a front-wheel-drive car like the 206, even with the throttle pressed, there's no issue at higher speeds, as front-wheel-drive cars have better directional correction capability. Snow/Ice Mode: Avoid skidding as much as possible. Apply less throttle when starting, or even start at a near-idle speed. In lower gears, the speed generally should not exceed 3000 km/h.
