Limitations? Like other CVTs and regular transmissions, the D-CVT is can only manage a certain level of torque, which can be approximately a hundred and fifty Nm. Daihatsu suggests its transmission is optimised to be used in all versions from mini (kei vehicles) to vehicles with motor capacities of around one.5 litres.
For more figures, the organization suggests that the gap in between the centre of your input and output pulleys in the transmission is simply 136 mm, whilst the space between the centre on the transmission’s enter and output points is just 168 mm, both of those claimed for being the smallest in the world.

CVTs involve inspection of metal belts; oil alterations close to each individual 60k miles. DCT clutch packs may have alternative about 100k miles.
The pulleys are connected by a belt. The main pulley is linked to the engine. The secondary pulley is connected to the generate shaft. Each individual pulley can grow and deal at the same time as a result of its moving sections.
