It’s all info and figures at this point, as Daihatsu suggests the split gears allow the gear ratio array of the D-CVT to get extended on both minimal and large sides from five.3 to seven.three. To the small aspect, it's an increased range of small ratios to handle acceleration, whilst on another conclude, significant ratios allow it to be much better suited for large-velocity cruising.
