Looking for a fuel efficent car for the wife. Will be used to bring kids to school, grocery, church etc.. Almost sure na pure city driving. She has a driver so I'm getting a base model manual tranny.

I know that we are only speculating on the Avanza but since its a 1.3 vvti, can I assume consumption will be similar or at least close to the vios? I know it is heavier and if fully loaded will seat 7 people. We are a family of 4 plus yaya and driver. I do have a 10 seater van pero gas guzzler so i'd rather not use it. Its used for highway and when we are all together. Vios is lighter and will seat 5. I'm guessing price will be similar. I'm pretty sure vios will have more promos.

I'm a bit concerned that Avanza might be under powered. Its supposed to be 89 hp and around 1085 kgs. Ok ba power to weight ratio nito? vios is supposed to have 85hp and curb weight of 930kg. So Vios has better power to weight ratio. Problem is I do not know what is the acceptable power to weight ratio. I can do the math but the numbers have no meaning.

So which one is better suited for my needs.
