Perodua statements a category-major gasoline usage figure of 18.9 km for each litre. Even so, as you will notice inside the video clip previously mentioned, it even now behaves like a standard CVT on comprehensive throttle cases, where it retains on to an incredibly substantial rev (in between 5,500 to 6,000 rpm) beneath really hard acceleration. It doesn't simulate any equipment alterations like certain newer CVTs from Toyota and Nissan.
