What is the Toyota eFour?
2 Answers
Detailed introduction about Toyota eFour is as follows: 1. Toyota has introduced two new four-wheel drive systems, namely the on-demand four-wheel drive system for fuel vehicles and the E-Four electric four-wheel drive system for hybrid models. In the future, Toyota will deploy 4WD systems based on 3 structures and 8 different versions for models including passenger cars, commercial vehicles, and hybrid vehicles. Toyota expects that by 2030, 70% of its vehicles on sale will use the new four-wheel drive systems. 2. The new on-demand four-wheel drive system is called the Dynamic Torque Management AWD system (Dynamic-Torque-Vectoring-AWD) by Toyota. Although the name includes AWD, this new four-wheel drive system is still only an on-demand four-wheel drive system, but with more optimizations in torque distribution.
I once drove my friend's Toyota e-Four, which was a hybrid RAV4. This e-Four actually refers to Toyota's electronic four-wheel drive system, featuring a separate motor on the rear axle to drive the rear wheels. Normally, it runs on front-wheel drive for fuel efficiency, and intelligently activates the rear-wheel assist only when encountering slippery conditions like rain or when climbing hills. Unlike traditional four-wheel drive systems that consume more fuel, it offers much better stability than regular front-wheel drive vehicles. The most noticeable feeling when driving is the lack of wheel slip on wet, slippery curves, and significantly better traction in snow compared to my neighbor's CR-V. Toyota has equipped this system on many hybrid models, including the RAV4 and the Wildlander hybrid version.
