Experience:
we have a 2013 civic so we are very bad at comparing because we just have a very good reference to compare to. Anyhow seat height is high, ride is bit stiff. Ride is better than swift but Handling of swift is better. Boot space is enormous. Petrol tank capacity is miserable.
Fuel economy:
Depends on how you are driving, where are you driving, and when are you driving.
E.g
LOCAL
1.it gives me 14-15 on expressway (1400 hrs and 2000hrs)
2. It gives my brother 16-17 on expressway 1700hrs and 0400hrs)
MOTORWAY
1. Around 15-17 kmpl 04 passengers. Around 100 kph
