Re: Mileage comparo: 1.3L Vios vs 1.3L Avanza vs 1.3L Sentra
Vios should lead the economy contest, being lower and shorter than the Avanza better engine technology than the Sentra, and lower weight than both. The Sentra, I think, should come second being lighter and more aerodynamic than the Avanza. I suspect the Avanza 1.3 will head the Lite Ace way, underpowered and undertorqued for a 7-passenger vehicle that would result to slow performance and/or not-so-good fuel mileage.
My friend's Vios 1.3 did as much as 17 km/liter, but economy runs should yield even better results.

No, RWD doesn't necessarily make a difference in economy. Compared to FWD, it's a bit heavier with the driveshaft in place, but the weight is better distributed. 4WD is another story though.

former sentra gx(m/t) owner. fuel consumption is 14-15 km/l highway driving with conservative driving (80-100km/h). Medyo malakas sa gas pag city driving( 7-8km/l) mabigat kasi body.
