Few days back i bought an unregistered toyota vitz 2008 1000cc. I can swear it is not giving me more than 8.9km/l economy. Firstly i thought it was because i kept the air conditioner on all the time but then i tried without the ac and still the same result and i dont drive aggressively at all, seriously i just cruise at 40km\h max in the city with no sudden accelerations and the rpm below 2000. I had the air filter checked it was clean and did not need replacement, i changed the oil, got the car tuned up but no change. I also own a Honda City 2011 mannual i-vtec and that 1300cc car with much more power than the vitz gives me averagely 13-15km\l in city and 23km\l long. I am planning to visit toyota showroom in Islamabad tomorrow and if i get any improvement i will post but till today my vitz is giving less than 9km\l although, theoretically with only 1000cc and continuous variable transmission(CVT) this car is supposed to give more than 15km\l.
Plus the car is in stock condition, i haven't installed bigger tyres or any other performance upgrade that might ruin fuel economy. Any one who knows a solution to this problem is very welcome to share their thoughts.
