What is the difference between automatic four-wheel drive and full-time four-wheel drive?
1 Answers
Automatic four-wheel drive and full-time four-wheel drive differ in the following aspects: 1. Different structures: Compared to full-time four-wheel drive, the structure of automatic four-wheel drive is simpler. Due to its unique structure, automatic four-wheel drive is more suitable for models with a front transverse engine and front-wheel drive platform. This makes it possible for many SUVs or four-wheel drive sedans based on this platform to be equipped with a four-wheel drive system. 2. Different power transmission: Currently, most automatic four-wheel drive systems are limited by their inherent structural defects when transmitting power between the front and rear axles, unable to deliver more than 50% of the power to the rear axle. This results in a smaller adjustment range for active safety control compared to full-time four-wheel drive.
