nissan use JATCO which is their own transmission, proton use cheap china brand punch CVT which is wet clutch transmission and it still been updated. current version is VT2+. the old FLX/persona using VT1. original IRIZ using VT2, while saga VVT, persona VVT, MC1 IRIZ using VT2+. some people said the new one might use VT3 but its just rumors. recently some journalist said saga facelift might using 4AT from korea
if not mistaken, proton starts with VT2, then into VT2+ which comes with improvement in terms of NVH, and the good thing (depends on how you put it) for proton is they continuously improves their ECU & TCU which improves the efficiency and operation of the cvt, as well as the throttle mapping. SOmething that Perodua doesn't bother to do on their cars. Not sure whether their tuning is already optimized, or they don't bother (since they sell so many vehicles already, no need to improve alreayd to secure for sales), or daihatsu doesn't give them support (i believe Perodua is like Proton during mitsubishi engine era, whereby they have no authority over ECU tuning).
For VT3, it is meant for Proton turbo models, the difference between VT2 and VT3 is the torque handling capacity, one of the reason of Proton CFE engine having a soft turbo is because of the shortfall of VT3 CVT where it only able to handle 220Nm max. Hence proton make the CFE engine to have 205Nm output.
Yeah, heard about the rumor of 4AT as well, if the 4AT is efficient enough it maybe not losing out too much of fuel efficiency compare to the Punch CVT.
Sorry for the OOT though.
Anyway, will really like to see peordua using cvt on their models, i wonder when perodua will implement cvt. it surely able to bring the fc to be even better.
