Restrictions? Like other CVTs and standard transmissions, the D-CVT is can only cope with a specific amount of torque, which is as many as one hundred fifty Nm. Daihatsu says its transmission is optimised for use in all models from mini (kei vehicles) to cars with engine capacities of nearly 1.five litres. Since kei cars and trucks are restricted to 660 cc by regulation, by using a max output of 64 PS (sixty three hp), the D-CVT is in excess of up on the activity. As with the 1KR-VET from the Ativa, it can make 98 PS (ninety seven hp) and 140 Nm, which happens to be very well inside of bounds of the D-CVT, Hence the pairing is effectively throughout the limitations. So, the impact on driving knowledge?
