Speed: 68-75 mph (using cruise)
Distance: 306.2 mi
Fuel: 6.201 gallons
psi: 29 front & 29 rear (yeah, it was low)
Tire: oem w/ ~27k miles
AC: on for ~ 2hours
Temp: 85 at start --> 65 at end
Mods: none
Load: driver only
Stops: 1 for dinner

I only wish I had a SGII to tryout hang-time pulse-n-glide.

-SC

p.s. After this wonderful achievement my gf drove the car in 30/70 (city/hwy) setting... and got only 33mpg. WTF!

i believed you, i did hit 55mpg over 70mph once. Now my average is about 37-39mpg which is 70-80mph on highway 70% hw and about 30% City driving.
Last week i took my yaris to myrtle beach from Buford GA to Myrtle Beach SC is 350miles trip, the road are flat terrain, hardly any traffics.
1. I left around 5pm filled up the whole tank, i drove by myself from GA to SC with 1 big bag in the back seat, and my laptop bag messenger with 12" sub woofer in the trunk plus cooler, clothes.....so basically it's pack. I did use CRUISE at average of 60-78mph never pass 80mph, i stop at the gas station when it's hit 300miles on my car to fill up my gas again and i did 37mpg average.
2. On the way back from SC to GA myself with all the bags, cooler..... plus 2 more persons and their bags. i have to say that i did 80-90mph on my way back just want to get home soon and followed the traffics, it's was daytime.
I was surprised that i got 41mpg when i filled up my gas today. No lie or bs here. I think it's more about about weather, gas brands, your foot, Traffics.....that make a big dfferences in MPG.
