my understanding which could be wrong IS, reducing space from your car and the road reduces the amount of air turbulence from under the car which would increase drag.

Maybe some how you really did reduce CD and that would be good enough explanation for me.

Drive like an old woman.

I'm at only ~240 miles or so but so far my MPG is 13.4 :x Seems odd -- I don't drive it THAT hard. But I know driving style has a lot to do with MPG

i just really wanted to know because i picked mine up last friday and i only have 200 miles on it right now. Ive been driving it a little hard but not too bad and my mpgs came out to be 16. I thought it was going to be around 19 or so.

True city driving (constant stop-go from stop sign to stop sign) will get you about 15-16 mpg. If you're solely on the highway, without a car directly in front of you, and doing about 70mph, you'll see about 22-24 mpg. The guys who get the higher numbers for city are actually driving along at a constant pace for a fair amount of time (it should be called 'sprawling suburbs' instead of 'city'). The 30+mpg numbers on the highway are either slightly downhill trips or readings people see when they're slipstreaming behind a semi-truck. The Z doesn't ever get a true 30mpg.

And the worst mpg I've seen is at the track with just 6 mpg.

+1000.... last night, I was trying to find the Z's mpg sweet spot with that lil meter. This is what I learned. From a light. Whether crawling off a red light or taking off like a bat out of hell you get the same result on the meter, except when u launch quick, you get up to speed fast so you spend less time wasting gas.

on the highway I noticed the best mileage is between 55 and 80. So take your pick on what speed you want to be at. It all gets you around 23-24mpg's. But if you use CRUISE CONTROL? There is where you will save an enormous amount of gas.

Last night in low traffic, I used CRUISE in the city at 50mph and was getting around 22-24 city.
(I have radar and most speed limits are 40-45mph, on huge wide low trafic roads. Tx is designed this way. Do not try in major cities with lots of people sharing the streets with you.)
On the highway I did 80 in a 70 on the left lane on cruise and was receiving a range of 22-30 mpg depending on terrain changes...

So if you want to save the most gas mileage, use CRUISE as often as possible. Get off the line fairly quickly to come to speed. Don't smash but don't crawl.

This is something I will definately preach more than practice. Its hard to save gas in a car this fun.

12 mpg is impressive

Stop caring about fuel economy when I bought the Z... that's NOT why I bought it!
