Help from mileage simulator?

I was just looking at the local weather and noticed that I'm in for a nice headwind on the way home today. This started me thinking about which of my typical routes would get better MPG, and which would use less fuel.

Would someone with one of those Prius mileage Simulator programs be willing to plug in some numbers for me and let me know what the mileage is likely to be for each of 3 scenarios? Thanks in advance.

General info:
74 deg. F.
Dry pavement
50% humidity
Tires at 44/42 psi
No A/C or heat
Headlights off
Starting elevation 818 ft
Destination elevation 597 ft

Scenario 1:
Cruise control set at 46 mph with 20 mph headwind from 0 deg.

Scenario 2:
Cruise control set at 46 mph with 20 mph crosswind from 90 deg.

Scenario 3:
Cruise control set at 55 mph with 20 mph headwind from 45 deg.

Any other significant variables I've forgotten to add?

Edit: I'm not sure that it matters, but I forgot to mention that Barometer is should be about 29.5 in. (maybe slightly higher 29.54 in.?)

 

Mostly good assumptions. I'm not sure what should be included in the weight variable, but aside from things the car came with (spare tire, cargo cover, floor and cargo mats), the only added weight in the car is me, less than 200#. As you mention, I doubt this will make a significant difference.

Thanks for the info.

In case you're curious, based on the info you provided, I'm looking at a choice between:

31.5 miles @ 51.268 MPG for a total of .614 gallons used
and
22.5 miles @ 41.32 MPG for a total of .545 gallons used.

So I can get a better "score" on my MFD MPG display but use more fuel, or I can pull my MFD MPG "score" down, but use .07 gallons less.


I suppose I could drive the 45 deg. offset wind at 46 mph but on that road I'd really be getting in the way of other drivers. The headwind to crosswind
route provides lanes for passing.

Either way, I'm headed out now. Thanks again.
