My boxy & short-geared xB is only good for 41 mpg @ 60 mph, & 49 mpg @ 50 mph. I've managed 60 @ 60 with a Prius, but I can't even get close with the xB. I have to P&G to top 50 mpg with my xB on highway trips. Those of you who aren't aerodynamically challenged are very fortunate.

Another test
Had to do a 27 mile drive today so I did a different test. Could I maintain a 60mph average while keeping a 60+ mpg average without engine off coasting? In the previous test I had used light EOC and got as high as a 66.7 mpg as a one-leg average of my test route. Forn this test, I allowed myself only engine on pulse and glide (55-65mph) and reasonable drafting whenever possible. I only got an opportunity to draft for a couple miles, and I followed the 2 second distance rule. The terrain was hilly. There was a fairly significant crosswind. The results:

You averaged 59.8mph... Epic fail. Just kidding. Great job!

Doing two way average runs over flat ground with the cruise set at 62 this weekend, I got an average of 53.8 from the on board computer corrected at -7%.
To achieve 60@60 I'll need some significant aero mods... The car is pretty much stock right now, except lowering springs and higher tire pressure. I'll be checking out your mod thread for ideas, but I won't be disconnecting the alternator!

I use the Ultra Gauge. I think it is the slightly older one. Mine displays 6 readouts at a time. Newer ones display 8, I think. But whatever gauge you are using, you need to calibrate the distance and the fuel usage measurements. Still, guys with experience here will tell you that only the MPGuino is really accurate as to fuel use because it monitors the injectors directly (using voltage signals, I think).

Good luck with the aeromods! You have a modding thread?

How recently, basjoos? I went to your fuel log & it looks like your last entry was 2 years ago. ???? Did the aerocivic break down, or?
