Thanks a bunch guys,
On highways, this is the most stable model ive ever driven of civic. Its steering gives excellent feedback of road. But the comfort level is not that exceptional nor its that much bad.
RPM
On 120kph the rpm is 2200 in D mode
and it reaches 3000 after 170+.
Averages
In the city, it gives 8-10 km/l where as on highway it has given upto 15km/l with AC. Otherwise 14 km/l is must!!! The game is of rpm. We usually drive on 140+ hence we get 14km/l or a bit lower otherwise if one drives at 120, 15km/l is must.
