Hmm. I wouldn't think the OS would be a factor, but perhaps it could be. I am on Windows 10. By the way, if you are interested, I wrote a script to turn off the telemetry and unnecessary services. Every time Windows did an update, it would reactivate it's crap, so I made something that automatically turned it all off again. Anyhoo, if you use a debloater and my script, it actually changes Windows 10 into something more reasonable.

Yes, fresh install kind of fresh. If you are on Linux, Safari or Opera are good choices.

Wow. The best I ever got from my grille block was 5%, and that was with something that I felt was unsafe to actually use. The grille block I settled on was around +3.5% mpg.

For the wager, yes. My actual goal is 70 mpg unladen with Champrius 4.0. I'm hoping to get high 60s by redoing the front, and then to refresh some other mods I already have to push me over the 70 mark. That would mean that once I dump in all my camping gear I should get mid 60s at 65 mph.

It's been a long time since I read about the areo civic, but if I remember right, the custom shaped nose cone vs the mostly (or fully) blocked off stock nose was good for like 5% difference.

That's everybody's understanding... because they haven't seriously considered modding the front as a whole unit. I'm not going to be doing what basjoos and everyone else has done. I'm trying something brand spanking new which I believe will be much better.

On v3.0, the boat tail got me +20% mpg. On this last version, it netted me +15%. It's pretty substantial.

The prius doesn't seem to do well for high speeds vs low speeds, I suspect it's because of the CVT setup with the electric motors and battery requirement (more drive line losses than a manual trans at high speeds), it really shines at low speed and 40mph and under auto engine off coasting and such. Can your car hit 65mpg at 65mph, I think you'll get close. At such high speeds, it might be better to remove the solar pane or rework the boat tail so it's flush, the leading edge and tunnel effect I think creates a lot of drag, even dropping it down flat and reworking the front and rear edges I think could see some reasonable gains.

Crazily enough, on the previous boat tail, the solar panel had negligible impact. If it reduced mpg I couldn't tell. I think it was because it was so well oriented with the airflow. On this version, I don't know. The v3.0 was flat and straight from above. The v4.0 version is more rounded and tapers in all directions. So the back edges of the panel are probably interfering with airflow.
Before all my car troubles, v3.0 got 66 mpg at 65 mph unladen. That's why I'm pretty optimistic I can achieve my claimed numbers; I've already done it before.

The Gen II Toyota Prius has a 0.26 drag coefficient stock, not 0.24. My previous version was around 0.21, and my goal is 0.185 Cd (good guesses!).
We'll see how things stack up against the Aerocivic once I'm done. Onward!
