What is the W gear in an automatic transmission car
1 Answers
Automatic transmission W stands for the snow mode. Here are the specific details about the automatic transmission W gear: 1. Although the snow mode of the automatic transmission W gear can save fuel to a certain extent, it is not recommended for prolonged use because driving at low speeds can easily lead to severe carbon buildup, which will ultimately affect the vehicle's overall power performance. 2. The automatic transmission W gear can be used for starting on slippery surfaces, as the wheel torque is equivalent to that of second gear, which helps prevent slipping on wet or icy roads. It is also possible to drive in W mode, but high-speed driving is not recommended. In this mode, the engine torque is restrained and does not quickly reach its peak, thereby reducing the likelihood of wheel spin and skidding when driving on snow and effectively preventing side slipping. 3. For automatic vehicles equipped with an ESP system, the 'snow mode' of the automatic transmission W gear is by no means a simple second-gear start. After testing, when the snow mode is activated in an automatic transmission, the vehicle's power output is effectively controlled in real-time within a range suitable for snowy conditions. The ESP body stability system, ABS anti-lock braking system, and ECU vehicle computer system work together based on wheel speed and steering wheel angle, using specific programming to ensure more perfect coordination of the vehicle's driving power.
