Here is what I posted when I had both of them side by side. I did put 205/60-16 Yoko Advan on my 9th Gen (as in pictures a few posts above) and that made it considerably better to drive in all aspects. If you get a 9th Gen do spend on tyres and rims.
Copy text as per my old I.D::::
I have a 2009 8th Gen driven 120000 but very well Honda Maintained and still drives like a 2012 8th Gen, and i also have a 2013 9th Gen driven 25000. Both Prosmatec which i drive alternately on different days and mood. Therefore i am going to provide you my comparison.
Acceleration: at first the 9th Gen did feel it's slow but first few thousand Kilometres it was fine. To be honest they both are equally fast and not that different.
Grip & Stability: 9th Gen is no where near 8th Gen. The 8th Gen is by miles a better car in this area. The stability of 8th at 200-km/hr is equal to 9th at 150-km/hr. 9th scares you.
Brakes: the movement and response of brake paddle in 9 is abrupt and hard while 8 is slightly soft. But the Grip factor makes overall braking experience better in 8th and 9th doesn't feel good due to grip.
Comfort: 9th is better than 8th around this area. It feels softer on potholes while the 8th was hard
The softness and added clearance in 9th has given it comfort but compromised grip & stability. Obviously for that it would have been hard and low which the 8th Gen. Gets very expensive for a car maker to provide a suspension which does both jobs good. But since its a Civic so they had to give either of the two.
Interior: The 9th feels much better, a bit more charming and further more futuristic.
Fuel Economy: Yes 8th is a guzzler and 9th is much better with fuel economy.
The 8th Gen had a hydraulic Power steering but 9th has Electronic. So 8th feels more responsive as it acts natural all the time but 9th steering feels a bit less accurate.
This change in steering is also a major reason for fuel economy aling with some engine tweaks. The hydraulic steering has a direct load on engine so consumes a few percentage of fuel with that load.
At the end of the day it's actually hard to decide which is better. Both have positive and negative points. But the 8th gen feels better overall in terms of drive. I have more inclination towards it specially when i have to travel on the motorway, its a bit more precise to control. I prefer taking 8th Gen on my trips.
The fulcrum accelerator pedal of 8th rising from the floor is much comfortable for foot as compared to low budget hanging pedal of 9th. Looks like in certain areas they degraded 9th Gen purposely to find excuses for giving a better 10th gen and cash the success they developed of 8th Gen to sell 9th as people would trust them.
The 9th is not a bad car but 8th gen was truely a car that was "Reborn"
Hope this long story (my opinions and some may differ) isn't boring
