Four-wheel drive structure GAC Toyota-Willanda

● Four-wheel drive structure

　 　 Although they are all hybrid models, the four-wheel drive structure is completely different. Wilanda adopts Toyota’s E-FOUR four-wheel drive system, and the rear axle has an independent motor to provide power output for the rear wheels. Different from the traditional four-wheel drive, its front and rear axles are almost independent, with the advantage of fast response and the disadvantage of limited torque provided by the motor. This four-wheel drive system is used in many hybrid models of Toyota. According to our previous experience, its off-road capability is very unsatisfactory.

　 　 Let’s take a look at Honda CR-V, which adopts the traditional timely four-wheel drive form, and transmits power through a group of electronically controlled multi-disc clutches, while the inter-wheel slip is limited by ESC. In theory, this four-wheel drive system can transmit up to 60% of the power to the rear wheels. From the structural point of view, its actual performance should be better than Willanda.
