I recently acquired a Vitz 2009 model with 1.0L engine. It is fitted with 185/70 tires. After my first fill up, I drove it 493 km till the last fuel bar started blinking. I refueled the car and the amount of fuel was 34.5 L.
So 493/34.5 = 14.28 km/l
The drive included 150 km on Motorway M2 (of which around 70 km were at the speed of around 140-150 km/h rest drive was 110-120 km/h). remaining 343 km were in Lahore including a traffic jam of around 1 hour.
Is it good fuel average? I have refilled today and lets see what it gives this time around.
