A crawler or low-selection gear mode optimizes DCTs for that specialized prerequisites like torque modulation expected in treacherous off-street disorders. CVTs absence the Regulate essential in slippery traction-challenged scenarios.
This can be attained purely due to the split gears, as there’s no need to have to make pulleys more substantial for just a wider gear assortment ratio.
Welcome to 50 percent three of our deep dive sequence into your Perodua Ativa (typically called the D55L), the place the most crucial focus this time is to the transmission that might be utilized by the compact B-section SUV.

over. At reduced to medium speeds, the belt travel is absolutely engaged, but at higher speeds, the D-CVT’s clutch pack provides the gear drive into Procedure, relieving the belt push.
