What gear should be used when driving uphill?

[MacHarper]

When driving uphill, the appropriate gear depends on the steepness of the slope, the vehicle's performance, and the climbing speed. Here are the relevant guidelines: 1. Manual transmission vehicles going uphill: The gear selection should consider the climbing power of your specific vehicle. Each car has different climbing capabilities. For gentle slopes, 4th gear may be sufficient - the key is to make proper judgment about the slope in advance and master the coordination between clutch and accelerator. This represents an economical, fuel-efficient and safe driving technique. 2. Automatic transmission vehicles going uphill: For most slopes, D (Drive) gear is adequate. The principle of automatic transmission is that after stopping, the vehicle always starts in 1st gear, then upshifts according to power demand and speed. Similarly, it will downshift sequentially based on power requirements and speed, hence the name 'automatic transmission'.
