almost every 660 JDM micro-van is as lazy as Snail. 1. because it is a CVT transmission, 2. it is for intercity commuting not for highways, 3. with aircon engaged almost 20% of engine power is dragged by the aircon compressor.
There is no solution to make a 660 JDM micro-van to become squirrel let alone competing to be a rabbit. live with it, it is your own choice to spend almost nearly a million for 660 cc junk. There was no harm doing some effort to locate a PKDM Corolla or Swift in that price bracket
