My 2009 Ford Focus Trend 1.8 MT (already at 5,000+ odometer reading) is consuming between:
1) City driving: 9.7 km/liter to 10.7 km/liter normally running between 80kph to 130kph
2) Highway driving: 13.7km/liter-15km/liter running between 100kph to 180kph (SCTEX)
To attain an optimize the fuel consumption (from Ford manual), you should be running between 1,500 rpm to 2,500 rpm.
They are advertising that Ford Focus can attain 16.7km/liter. I think this is attainable if you will fully maintain a speed of 80kph-90kph without aircon, hehehe
