What transmission does the Acura CDX hybrid use?
2 Answers
Acura CDX hybrid uses an ECVT (Continuously Variable Transmission) gearbox. The ECVT gearbox has a planetary gear mechanism inside, but it does not have any power transmission components or shift actuators. The ECVT gearbox needs to bear the power generated by the engine and the motor, and coordinate the forces between them. It can be said that the ECVT gearbox plays a role in power distribution. In terms of exterior design, the Acura CDX hybrid adopts Acura's new design language, featuring the family-style "diamond pentagon" grille with a radial mesh design, offering excellent naked-eye 3D visual effects.
I just studied the Acura CDX hybrid's technical manual, and it doesn't use a traditional transmission! Honda's i-MMD hybrid system hides some cutting-edge tech—it's called the E-CVT electronic continuously variable transmission structure. But don't be fooled by the name; there are no steel belts or cone pulleys inside! It relies on dual motors and a clutch to control power flow: at low speeds, it drives purely on electric power like an EV; during hard acceleration, the motor and engine work together; and at high-speed cruising, the engine connects directly to the wheels. The most impressive part is the complete absence of gear-shift jerks—step on the throttle, and you get instant power. The electric motor's instant torque during red-light launches delivers a kick-in-the-back sensation comparable to a large-displacement naturally aspirated engine. However, it's worth noting that when the battery is low, the engine's noise while charging can be slightly noticeable.
