What RPM's are you americans getting on Auto trans?

[BMGYaris]

if anybody has installed a tachometer on your auto trans id really love to know what RPM's you are getting cruising at 60, 70, 80, and 90 mph

i pretty much always drive highway, lots of country here, and I'm always at 80, sometimes 90....im getting about 26 mpg. im thinking it must be bringing down some pretty high RPM's at 80 since that is my usual cruising speed if im not passing, so some of that info would be awesome.

Well driving at thoes speeds will destroy your fuel mileage.
Back off to the speed limit and you mileage will increase a huge amount.
The car was designed as a comuter car not an open road speedster, it was geared for optimal MPG around 55 mph.

My Canadian Automatic

100kph = 62mph = 2600 rpm
120kph = 74mph = 3100 rpm
130kph = 80mph = 3400 rpm
140kph = 86mph = 3700 rpm

I look at it this way,when I want speed,this car will do it,and still be good on gas,when I want to save alot of money,I slow down.

yeah thos rpm's posted above are right on with what i have been seeing :)

[vodkalush]

same here. My RPM's used to be lower around 65mph = 2500rpm but after changing my driving style it seems to have jumped to around 26-2700 rpms.

Do you think that the car is kind of adjustable according to your driving style?

Ill check mine on the way to work today,Ill post about 8:00pm est.

well the thing is, is that I've changed my driving style to a less agressive one but my RPMs went up.:iono:

[BMGYaris]

so i guess just going by the rpm's then the 74 mph is probably going to yield a pretty decent balance between speed and mpg? what do you guys think? ugh, im going to hate slowing down, wish i could own two cars:) oh, and wouldnt the rpm's be pretty different with the 1.3 and 1.5? or roughly the same?

[vodkalush]

remembering back to my trip to boston, 110mph = 4100rpm

and has anyone else noticed that on longer trips if you stay a constant speed on a flat surface that your rpm's drop (nothing big mind you). I'm talking like a line/bar.

[eco]

60mph=2560rpm
65mph=2802rpm
70mph=2980rpm
75mph=3196rpm
80mph=3459rpm
90mph=3869rpm

[BMGYaris]

60mph=2560rpm
65mph=2802rpm
70mph=2980rpm
75mph=3196rpm
80mph=3459rpm
90mph=3869rpm

Thats a little encouraging. I'm afraid because this ismy first car that over 90 in, I sortof over did it on my first 100 mile road trip i took. i bought it with 8, took it home pretty slow, so by the time i drove it back to college it probably had, maybe 50 miles on it. I didnt gun it, but the manual didnt have a top speed and there was no tach, so i drove most the way 80-100 and one timei hit 110 just to see if i could.... That tank i got 29 mpg even though they hadnt fixed the alignment and the front tires were 4 psi underpressure i soon found out. and now this last one i havent gone over 80 mph, dont gun it, and i have gotten 24 mpg...so i am very scared if i hurt my car....but maybe if it was under 4k rpm's most the way it is something else causing such unbelievably low mpg

[eco]

That is very low,I gun mine all the time,have 7.5" width tires,go over 100 alot,mostly 85,and still get 35-37mpg on average,but Ive heard that the CAI,and lowering the car,and lighter rims,and better exhaust,bigger headers,bigger intake manifold,and some others,all will help in giving better fuel milage if you dont have a lead foot.
