Limits? Like other CVTs and usual transmissions, the D-CVT is can only manage a certain quantity of torque, which is up to a hundred and fifty Nm. Daihatsu claims its transmission is optimised to be used in all designs from mini (kei vehicles) to cars with motor capacities of as much as 1.five litres. Since kei vehicles are restricted to 660 cc by regulation, which has a max output of 64 PS (sixty three hp), the D-CVT is more than up on the undertaking. As for your 1KR-VET from the Ativa, it makes ninety eight PS (ninety seven hp) and 140 Nm, which happens to be properly within bounds of the info lebih lanjut D-CVT, Hence the pairing is perfectly throughout the limits. So, the effect on driving working experience? To summarise, the D-CVT must give easy acceleration up to medium speeds, but with greater fuel use as well as a quieter travel at higher speeds.
