MPG of the freeway at 70mph?

[blanthony]

Just wondering what most ppl are getting at 70mph on the freeway. I feel the car handles just fine but want to know what type of MPG to expect at that speed.

Terrain and weather will have an effect, also, whether or not you're running the A/C.

I was getting high 30s & low 40s on my recent lap of the eastern US, with the cruise control set at ~70 (anywhere from 68 and change to 72 and change indicated on the GPS; my speedo reads about 3mph slow).

We averaged around 47 MPG at 70-75 mph on one of our trips up to Buffalo.

The buffalo trip must have been no-AC.

check our fuelly.com - you wont find exact mpg at 70mpg, but you'll find the average mpg of many smart drivers (including many on these forums). Probably best to look at users from your area, as terrain can have an affect. For example-don't take my lower MPG's as a sign of what you'll get--I live in a place with many stop signs and steep hills.

[jefferios]

At 70, mostly flat with AC and or a window down, 37-40 like others.

15-17mpg but don't take it from me, I'm still driving a land yacht.

But once I did get 30mpg in the Envoy. Downhill on the Interstate with cruise set to 75mph.

I suppose I could push the smart to the limit...

We do 75% highway driving and get 41 to 43.
