In Houston my city mileage has been averaging 18.9 mpg and my highway mileage just recently to Dallas averaged 28.7 mpg at an average speed of 74 mph with the cruise control on most of the way.

 

I've gotten 28.7 with my top up doing 60-65, same conditions with the top down I was only getting about 25. City: I get about 20 mpg.

 

I average 30mpg on the highway cruising at 130kmkh (85 mph). This car is definitely a hwy car in terms of efficiency with the torque and the tall 6th gear.

 

21 in town and 28 on the highway.

 

daily driver: im getting 25.25 doin the 100% accurate test.


* take your miles from last fill up and divide that by the amount in gallons it took to just fill up

 

yeah I wouldn't base my mpg on the digital read out it's sometimes off by as much 1 mpg (still pretty accurate).

 

600km on a full tank

 

REVIVED THE POST!! Haha sorry, I was also curious. I just bought my 05 Touring a/t (I know, I know...) in Dec. this year. Left it at my folks house until winter clears out up north so haven't done much Hwy driving.

However, when I first got it, of course I was a little punchy with the gas as well as was dealing with 5o clock traffic : 9mpg
Regular city driving: 19.5

I then located the sport shift and was driving in 3rd around my hometown at about 35mph and was averaging 34mpg according to the computer until I hit a red light not far down the rode from where I reset it. It was a long light and it dropped to 26...

Edit: Didnt realize the "ZR" part... Im a coupe
