Has anyone (in these reviews or elsewhere) published an acceleration test for the 2020? Ideally someone who also tested a prior year 10th gen Si. I still haven't seen anything concrete regarding the impact of the final drive change. I've read some comments along the lines of "it feels a little bit faster" but I'd like to see some actual data, if it exists.

Making the gearing shorter will definitely increase acceleration, but will affect top speed. Many 2020 owners are reporting that at 70 mph their rpms are are nearly at 3000 while 2017-2019 don't see this rpm until around 80 mph. They will also see more power at cruising speeds because of the smaller gearing

Reading The Drive's review they had the same complaint Alex on Autos did. That new final drive helps with passing power but the high speed highway drone is a bit annoying.
Funny enough, the main knock against the updated 2020 Civic Si is the only mechanical change Honda made: That final drive gear ratio. The previous 4.11:1 setup allowed the Civic Si to hum along at 75 mph in sixth gear with the engine turning below 3,000 rpm, while the new 4.35:1 ratio has it droning around 3,500 rpm. That sounds like a small difference until you're subjected to it for a few hours straight. The extra passing power is noticeable, but so is the 2-mpg penalty versus the 2019 model. We're pretty sure Civic Si buyers didn't mind dropping to 5th or 4th gear for a left lane surge anyway.

It should not run at that high RPM till around 80 mph. My 2018 would just hit 3K rpm around 80, the 2019 has the same gearing

I feel like the difference in RPM is being exaggerated, although I don't mean to downplay the negative effect of an extra 100-200 rpm at cruising speed.

The 17-19 Si sits at ~2,250 RPM at 60 mph. With the 6% ratio change the 2020 will sit at ~2,380 RPM at 60.

This translates to the 17-19 sitting at ~3,000 at 80, and the 2020 sitting at ~3,175 at 80.

Not even a 200 RPM difference, whoever the reviewer was that said it sits at 3,500 RPM at 75 needs to go for an eye appointment..... Or upshift to 6th instead of cruising in 5th.

Yes, I understand that...this is the impact a final drive change should have on the gearing (better acceleration/penalty at top end, and associated mpg considerations). But I'm wondering about actual impact/numbers. Nobody has published 0-60 for the 2020?
