people who think that when these 660cc cars dont do more than 11-12 then whats the use of it , its only names 660cc ,the car can easily compete with local 1000 cc because of the power it has , n then these are auto cars , 660cc category was only made to carter the parking issues in japan they should be in limited size n limited engine , they were never made to do wonders in mileage , a 1000cc vitz gives around 10km while a new premio 1500 cc gives 12-13 easily does that mean vitz is bad , bigger the engine the car will run in lower rpm n u`ll get better mileage
