This car is not that heavy, i have another, mk1 fabia and they have similar weight and similar power while the older one have a little more torque and more displacement, both weight around 1000kg, the 1.0mpi is the lightest configuration.The worst scenario for my car is two adults, two children and some luggage and for now it handles it great, if i need to haul some more weight i have another vehicles, it is solely for transporting people and for most of the time its just my wife and one child. What i want to achieve is to have lower rpm at around 120kph since i dont se any reason to go faster with this car and sitting around 4k rpm for extended period of times doesnt seem healthy for the engine imo. Adding to that, this engine seem pretty happy on 5th gear at 2000rpm which is around 60kph thats why i think 3rd and 4th gears are useless, with a little longer second gear i might as well change to 5th and dont downshift for most of my driving. It is more of a theoretical question if it is possible at all and if yes, and not with that much hassle, a thing to consider while my clutch finally gives up (200kkm and original clutch). And also little lower rpms at 90-100kph where this car spends most of its life would be nice and from what i researched so far 6 speed from 1.0 tsi have ratios that i would consider acceptable (6th gear would be used very rarely but it would be nice thing to have on a flat highway). Also i dont really bother with changing gears as the car suggest on a display, i am a driver with 15 years of professional experience and know when the car is struggling and i am almost sure that little lower rpms at higher speeds are not something this little engine wouldnt handle. I plan to keep this car for a while and switched from a larger diesel because of poor fuel economy.
