I have done a long drive on this weekend:
KMs: 242 ( 80% long and 20% city drive)
Tank to Tank filling: 10.67L (2300)
242/10.67=22.68/L
New swift is giving excellent fuel avg with medium foot as well. i do have heavy foot but this time i tried to remain calm as much as possible but still i drove the car with heavy foot many times. Car stability was excellent, breaking was good and shocks were acceptable. overall very good experience Masha'Allah
