On my first trip I averaged 26.2 mpg on a trip from Waco TX to Longview TX. This was a 60/40 hw/cty mix. Car has 1,450 miles at the time. Shell 93 octane and I did not beat on it but on the open stretches I ran 75-80 mph.

Those are great numbers. My best so far is 24.3 mpg on long distance runs to Northern California averaging 80mph. Are you calculating it by: Miles Driven/Gallons filled?

i get 25-26 mpg cruising at ~ 75 mph. cruising at 55 mph, i have even got 30 mpg. these numbers are regurgitated by the trip info computer, not sure how trustworthy it is.

My around town and mixed driving gets me between 20 and 23MPG. I think that is really great for a car with this Fs potential. It's better than my G35 was.

I get about 16.7L/100km (~14 mpg) on my first 2900km (1800 miles). However, I treat my gas pedal as an on/off switch rather than a variable ;)

I've gotten 26mpg as well with tons of freeway driving and not going over 75mph. I usually average 18-22 mpg with mixed driving.

Mine stays around 15mpg in suburban driving. Mostly because of all the stop signs and lights I have to pass getting to school, o and minivans cutting me off.

My wife drove my neice back to Waco from Longview and she is a little lighter on the go pedal and got 28mpg. This was going the long way down I20-I35S. 240miles/8.5 gallons=28.23 mpg. I love this car!

My MPG have been pretty poor, ever since I got the car. I'm averaging 16-17mpg combined driving, and most of that is highway. Part of this maybe that when I'm on the highway, I'm usually doing about 75 to 80mph...okay, mostly 80mpg :p . But would that make such a huge deal on knocking down the MPG than if I was doing 70mph?

I'm glad you said this, because this is exactly what I am getting for mileage, 16.8 avg lifetime to be exact. I also run mostly highway and cruise at 80 mph. But in my case, it's the first 1200 miles, so maybe it will improve now that its broken in a bit.

This week has been raining so I have been avg 20-22mpg. I usually avg about 17mpg on mixed city/hwy driving conditions, majority of it being highway. When i feel a little spirited, I avg about 15mpg with sport mode on. Suprisingly with the car being under 2k rpm most of the time, even between 70-80mph, like some of you have mentioned, the mpg keeps climbing!

All highway when going 70-75mph the whole time I get 26-29mpg.

All highway when going 80mph the whole time I get 24-25mpg.

I get an average of 315 miles on a full tank when I drive all highway.

Street I drive ridiculously sometimes so I ignore the mpg.
