Well I finally had a chance to get my ZR out on the road this weekend. We went up to Flagstaff to visit (& feed) our son who is going to school up there.

I put about 300 miles on the car. Phoenix is about 1,500 feet elevation & Flagstaff is about 7,000 feet. Pretty decent elevation gain. It was all freeway driving and I kept it between 75-80 all the way (except for the slowpokes going up the hills in the left lane).

When I got home my trip computer showed 24.5 MPG and I calculated it manually at 24.2 MPG. I will admit that I am not one of those 'spirited' drivers, but I seldom let anyone pass me this weekend. All in all I was very pleased with the mileage... and it is a GREAT ride on the open road.

 

That's pretty good MPG. I've been able to get 27 MPG doing a steady 70-75 on fairly level highway and as "bad" as 23 MPG in weekday commute traffic.

 

I get about 19 mpg around town and 24 mpg on the highways.. I get the same in my G35 Sedan...

 

I drive that route a lot visiting in-laws in phoenix. Lots of winding turns going up and down flagstaff.
