The new Vios still uses the same 1.5li (1NZ-FE) and 1.3li (2NZ-FE) engines from the previous gen Vios. Fuel consumption should be more or less similar.

Toyota Vios (1st gen)// 1.3 li VVT-i (2NZ-FE) //m/t // 16.8km/li
Toyota Vios (1st gen)// 1.5 li VVT-i (1NZ-FE)// a/t // 15.34km/li

I'm guessing those results are from mixed highway and city driving, with more mileage covered in the highway.[/quote]

Gen 2 Vios is 100kg heavier than gen 1 Vios, thus fuel consumption may vary. I hope gen 2 Vios users will post their FCs and also Yaris users. I'm contemplating on Vios E or Yaris MT as P13K lang yun difference sa price.
