M gear is the manual mode of automatic transmission models, while S gear is the sport mode of automatic transmission models. The relevant introduction of automatic transmission cars is as follows: M gear is the manual mode in automatic transmission models. When shifted to M gear, the driver can manually control the upshift or downshift of the transmission without stepping on the clutch, and the engine will not stall, just like in automatic mode. M+ is for upshifting, and M- is for downshifting. M1/M2/M3 displayed on the dashboard represent the 1st/2nd/3rd gears in manual mode. The number of gears in M mode depends on the number of gears in the automatic transmission. For example, a 7-speed M gear has 7 gears. M gear is very useful in scenarios such as overtaking, going up and down slopes, driving on slippery roads due to rain or snow, taking curves, and high-speed driving. For example, using M- to downshift during overtaking can provide high torque, allowing the vehicle to accelerate quickly in a short time. In S gear (sport mode), the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer time. This allows the car to run at low gear and high RPM for an extended period, resulting in greater torque output and acceleration. Sport mode can increase the engine's power output in a short time, achieving instant acceleration.

Does Idling Consume More Fuel?

Vehicle idling does consume more fuel. The following are the reasons related to idling: 1. The air intake of the car is affected: During idling, the air intake of the car is affected. At this time, the car cannot inhale enough air for fuel combustion. In this state, the energy released by incomplete combustion of gasoline is far less than the heat generated when the car has sufficient air intake. However, the engine still needs to provide the energy required for the normal operation of various parts of the vehicle, so more gasoline is consumed. 2. Torque and fuel injection increase: During idling, the engine must be ready to respond to the driver's starting operation. When starting the car, it changes from a stationary state to a moving state, so the engine needs to exert greater torque than during normal driving. The amount of fuel injected by the fuel injector will be slightly more than during normal driving. Additionally, the engine speed increases during starting, which also increases fuel consumption.
