What MPG are you getting at 70 mph?

I do around 41.7mpg doing 70 on the freeway.

I'm also in Minnesota, and regularly drive down I35 at 70mph. I have a manual transmission.

In the late summer/early fall I was doing about 40-41mpg, with the factory tires. Two weeks ago, with winter tires (aired up to 50psi) and with temperatures at varying between 5 degrees and 20 degrees, I was getting about 38.5mpg.

Like others have said, the car is great for around town/lower speed highways. I wish there were a higher gear for interstates.

I'm getting 39 - 44 mpg US with cruise set at 110km/hr (68.35mph) in temp ranging from -5 to -25°C on winter Dunlops with my CVT.

Added Note: I leave the air cond. in auto mode so it's pretty much always on even in winter.

I have my tires at 35 psi all around. Still on the stock Enslaves. I average between 39-41 mpg according to the gauge. I usually average about 270ish on a full tank with commute averaging around 70mph. Not bad considering the high amount of traffic going through the cities + the cold weather.

I live in Florida, my tire psi is about 34 and we always have AC on and the tempature is about 80-90f I get 34mpg driving 80mph on the highway and some local driving. 260-270 miles per tank

Freeway/Interstate travel is the Mirage's mighty downfall. MPGS plummet due to the idiocy of not having a 6th gear for 70+ cruising. I can document 39-41 mpg at 70+ speeds, 80k miles worth. With a 6th gear, I'm convinced my avg would be a solid 5 mpgs better

...I get 34mpg driving 80mph...

Do you have a CVT or 5-speed? My 5-speed rarely sees over 60mph...lol. I can't imagine this thing at 80. That would have to be around 4,000 RPMs in a 5-speed car?

[25Plus]

What would be the problem with 4000 RPM?

If you are driving the same gear, the crankhaft will turn exactly the same numbers on a given distance, no matter the speed or RPMs. It´s only a question of the design of the motor, if this would be harmful. It may be better than driving with 800 RPM all the time...

A taller gear won't overcome the additional aerodynamic drag of increased speed. When it comes to fuel economy, speed kills.
