What is the difference between ECVT and CVT?
2 Answers
The differences between ECVT and CVT are: 1. Different structures: ECVT consists of planetary gears and two electric motors; CVT is composed of two sets of pulleys and transmission belts, oil pumps, torque converters, actuators, sensors, and control computers. 2. Different power solutions: ECVT is the electric transmission mechanism of Toyota's strong hybrid solution, capable of achieving electric drive, continuously variable transmission, and energy recovery; CVT is an ordinary mechanical continuously variable transmission. Both ECVT and CVT are types of transmissions, and their functions are: to change the transmission ratio to expand the range of torque and speed changes of the drive wheels, adapt to frequently changing driving conditions, and allow the engine to operate under favorable working conditions.
ECVT and CVT sound like siblings, but they drive quite differently. I've tested many cars, and CVT is a regular transmission that relies on physical belts and cone pulleys to change gear ratios. During acceleration, sometimes the engine roars loudly but the speed increases slowly, often giving a rubber-band effect with noticeable jerks. ECVT, on the other hand, is specifically designed for hybrid vehicles, like the Toyota Camry Hybrid. It uses motors and planetary gears with electronic control for shifting, making the entire process smooth and seamless with lightning-fast response, especially when accelerating from a stop at traffic lights. ECVT is also highly efficient and energy-saving, capable of recovering energy to save fuel, resulting in a quieter and more stable driving experience overall. Although ECVT comes at a higher cost, the long-term fuel savings and environmental benefits make it a worthwhile investment. Personally, I believe ECVT holds greater advantages in the trend toward hybrid vehicles, significantly upgrading the daily driving experience.
