What does 4wd-auto mean?
2 Answers
4wd means four-wheel drive. There are three modes for four-wheel drive: 4wd-eco (two-wheel drive mode), 4wd-auto (automatic four-wheel drive mode), and 4wd-lock (four-wheel drive lock mode). Below is an introduction to 4wd-auto: In 4wd-auto automatic four-wheel drive mode, the four-wheel drive system adjusts the torque distribution between the front and rear axles based on the traction of the front and rear wheels. This mode can be used at both high and low speeds. When driving on unpaved or slippery roads, this mode can be used to improve driving safety and stability. However, compared to two-wheel drive mode, four-wheel drive mode will increase fuel consumption.
After driving for so many years, I often get asked what 4wd-auto means. It's actually the automatic version of four-wheel drive, meaning the vehicle system automatically determines whether road conditions require switching to four-wheel drive mode. For example, on rainy days or muddy roads, it responds immediately when the wheels slip; on normal roads, it saves fuel by using only two-wheel drive. This feature is very practical on the SUV I drive. I remember last winter when it suddenly snowed in the mountains, it automatically switched and stabilized the car, preventing an accident. Although the fuel consumption is slightly higher, the safety factor is much greater. I recommend everyone prioritize this feature when choosing a car, especially for those who often travel. It can work with the stability control system to enhance the overall driving experience.
