I have a 2007 Nissan Versa 6MT.

I drive 120 miles each day, mostly highway except for 30 miles of stop-n-go. For the first 6 months, I drove normally, tracked each tank and got 30 mpg.

I bought a Scan Gauge last month and am trying to achieve better mileage by slowing down, drafting, coasting, cruise control, etc. So far, I'm getting 34 mpg.

I am on a quest for better mileage, but Versa manual trans is geared to steeply.

I just figured out how to get mileage image into my signature.

Nice job! What is your RPM at speed in 6th gear? What is the speed you usually drive on the highway?

From http://autoreview.belproject.com/item/93, the tires are P185/65R15, for a circumference of 6.40 feet.
6th gear: .8108
Final drive: 3.9333
total: 3.189

tire rev/mile = 5280 / 6.40 = 825
engine rev / mile = 825 * 3.189 = 2631

rpm @ 60mph = 2631
rpm @ 70 = 3069

*Whew!*

It is a bit short, you're right.

Thanks, Andrew!

That looks comparable to what I see on my tach in the Elantra. You should be able to pull some nice results out if you are aggressive enough with your techniques. :)

Don't forget to pump up those tires to max sidewall air pressure and if you have not already, be sure to read Beating the EPA - The Why’s and how to Hypermile. (http://www.cleanmpg.com/forums/showthread.php?t=1510)

Welcome to the site. I'm very interested in what you get out of the Versa as I have a similar vehicle (Toyota Matrix). Good luck with it.

The cvt trans has a much better ratio, but I like the control of the manual.

I've done the calculations and I'd like to have a 2.27 final gear made for this car instead of the 3.933. Then I can select the proper gear for the job. Looks like it will cost over $1000 to build. This is on hold for now.

I have been cruising at 61 behind the trucks (who are technically speeding). Sometimes I get a rogue truck going 68 and I jump behind.

The tires are pumped up to 40 psi. It seems low for the tire, but that's what the sidewall max is.

The big gain for this car is drafting. It's kindof a brick. I rarely let the tps go over 15% while accelerating and shift around 2200 rpm.

With this car as I suspect with many, there is a direct tradeoff between speed and mpg.

Will lowering the car 1-1.5 inches gain anything in mpg?
How about removing or replacing the side mirrors?
What about thinner tires/wheels?
What other hardware changes can be made to make this better?
Does anyone have any real before/after data?

Check out the pulse and glide technique. Thats were your going to see the big numbers (40+).

Does P&G really work (or is it practical) on a highway at speed on level ground?

On the same 150-mile highway route in my Civic:
43mpg - 65mph cruise control
57mpg - 55-70 P&G
75mpg - 45-60 P&G

Yes, it works.

Andrew, was that P&G with FAS? I've only been doing NICE-ON in mine on the highway because of the reboot time...
