At better speeds like while highway cruising, the CVT is at its maximum doable ratio, which could even now lead to the motor currently being at a superior rev issue that isn’t excellent for gasoline economic system. A person approach to extend the gear ratio choice of a CVT is by increasing the dimensions of your pulleys, Despite the fact that This can be counterintuitive In the event the unit should be smaller.

It doesn't simulate any equipment alterations like specific newer CVTs from Toyota and Nissan. Now this is something users must get used to, especially if they’re coming from a traditional torque converter automated like Perodua’s personal 4AT.

It’s unclear, on the other hand, In the event the Perodua version will feature exactly the same functionality. CVT is the best way ahead for Perodua
The Command program also can modify the equipment ratio determined by the driving force’s preferences, which include sport mode or eco method.
Lead to: Rattling noises can happen due to free or ruined elements within the transmission or maybe the bordering parts. This could be some thing so simple as a free heat protect or a more critical difficulty within the CVT.
