In this warm weather, I cruised 250 miles Tuesday and Wednesday on the freeways here and averaged 64.xx mpg. My speeds varied from 55-60mph. With a few more good aeromods, maybe my long sought goal of 60/60 cruising (60 mph and 60 mpg) is almost in reach.

At a steady 60 MPH my Fiesta will push just past 50 MPH.

MPG MPH MP?

Congrats! 60 at 60 is Gen 2 Prius territory.

I have a saying for my Firefly: "70 at 70". But that's MPG (US) at km/h.

My stock Fit is 50 @ 50, so your result is impressive.

Very nice!

60@60 is about what the TDI manages. Having a 6th gear helps

What RPM are you at going 60 mph? Do you contribute your success to the aeromods or the long VX gearing, or a mixture of everything?

I've got to repair my HX transmission and I have been thinking about just swapping it for a VX instead of repairing. Right now I am at 2250 RPM at 60 mph. I have slightly taller tires than stock.

I'm around 1950rpms at 60mph. The '93 CX transmission is without doubt a big factor, but I follow the idea of getting a bunch of small benefits from multiple mods--weight, engine, and aero--together and "stack" them up until it equals a big difference. The biggest benefits seemed to come from deleting the power steering and the alternator. Deleting 200+ pounds in weight from the car. Pumped up tires. And the airdam and grill blocking. I think the WAI helps too--or at least my testing suggested it did.

I did very little hypermiling, by my standards, on this trip. So the engine kill switch was less significant than usually. I held steady throttle as much as traffic or hills permitted. At some stretched the instant MPG reading would cross 70. At others it would be under 60. I did some mild drafting, one or twice cut the engine, coasted in neutral down the rare large hills or when traffic piled up in front of me.

Warm weather helps a lot. I won't get this number in the winter.

Need more aeromods!

70@70 below 1000 ft elevation and 75@75 above 2000 ft elevation in the aerocivic. The mileage improves with altitude.

Way cool. Thanks. It's a fun ride these days, but I want that last measure of economy. Want to get to 60/60.
