The Vios actually weighs lighter than the City ler...Vios at 980 Kg and City at 1,000+ Kg..but i must admit.. the rear of the City feels light when ur attempting corners but it very nice to drive in. Vios on the other hand does not feel stable at high speeds..seems very fragile once u hit a certain speed. however, this may vary from different drivers hehe..just my own opinion. perhaps a change of rims wud do the trick?
