Why is the sound so loud in M mode?

The reason why the sound is so loud in M mode is because manual upshifting has not been performed. Below is an introduction to M mode: 1. Introduction: M mode refers to a setting on the full manual camera function dial. 2. Function: In addition, the function dial of a full manual camera also has P, A, and S modes. Generally, digital cameras refer to P, A, and S as partial manual functions, while M is called the full manual function. 3. Method: M mode can also refer to a gear position in cars with manual-automatic transmission. This means it can shift automatically or manually. By moving the gear lever to the M+M- symbols, pushing the lever towards M+ will increase a gear, while pushing it towards M- will decrease a gear.

The louder sound in manual mode is mainly because in M mode, the engine maintains higher RPM before shifting gears, unlike automatic transmissions that upshift early for quietness and fuel efficiency. At higher RPM ranges, the combustion process becomes more intense, and mechanical noise increases, allowing you to clearly hear the engine roar and feel the power surging. This design is intended to give drivers more precise control over acceleration and deceleration, especially when climbing hills or during rapid acceleration, where manual operation can extract maximum torque at the cost of increased noise, which doesn’t harm the engine. Those accustomed to the quietness of automatic mode might find M mode a bit unfamiliar at first, but after driving it a few times, they’ll appreciate the sense of control—the louder sound even adds a thrilling, race-car-like excitement.

When using the M mode, the increased noise is actually due to the transmission responding more sensitively. The system follows your commands to delay the shift points, allowing the engine RPM to climb higher before shifting to the next gear. Higher RPM naturally makes the engine roar louder, with vibrations and sound waves intensifying several times over, making the car feel more aggressive. This is intentionally designed by engineers to let you utilize high-RPM power output for sustained acceleration when overtaking or taking sharp turns. Automatic transmissions shift early for smoothness and fuel efficiency, but manual mode sacrifices some comfort for driving excitement. If the noise bothers you, try easing off the throttle or switching back to automatic mode. New cars generally don’t have issues—the amplified sound is just normal performance release.

Shifting to M mode makes more noise, mainly because the engine RPM increases. In automatic mode, the transmission intelligently shifts gears at lower RPMs for quietness and fuel efficiency; but under manual control, it follows your command to delay upshifts, often keeping RPMs above four to five thousand, which amplifies engine noise. This actually enhances the car's responsiveness, giving you a greater sense of control, especially during quick acceleration in the city or high-speed overtaking. After driving it a few more times, you'll get used to it—the noise isn't a problem but a characteristic. Just make sure the engine oil and exhaust system are in good condition.
