The Difference in Usage Timing Between M Mode and S Mode

[HZoe]

S mode represents the sport mode of a car, suitable for situations such as climbing hills or overtaking; M mode switches to manual mode, which is also applicable for hill climbing, but M mode is only available in vehicles with a semi-automatic transmission. By moving the gear lever to the right, the transmission will automatically switch to manual mode. Below are the relevant introductions: 1. Usage of S mode: When the car is in S mode, the engine operates at a high RPM. Under high RPM, the fuel injection volume increases significantly, leading to higher fuel consumption. Although the driving speed of the car will increase momentarily, prolonged use with delayed upshifting will impose a greater load on the car's transmission, thereby causing wear and tear. 2. Usage of M mode: During driving, M mode represents the semi-automatic transmission, where M stands for manual mode, including M+ and M-. Simply put, it allows for both automatic and manual gear shifting. M+ and M- are only equipped in models with semi-automatic transmission. If the gear lever is positioned between the M+ and M- symbols, pushing the lever towards M+ will increase a gear, whereas pushing it towards M- will decrease a gear. 3. Usage in overtaking situations: When overtaking, you can immediately switch to S/M mode, manually downshift to utilize the transmission's low gear with a large gear ratio, outputting high torque to rapidly increase the engine RPM. This enhances the car's acceleration performance, reduces the time needed for overtaking, and improves safety.
