VQ's (3.0,3.5 3.7)s have never been that fuel efficient especially the 3.5 and 3.7. Having had 6 cars with it in them, it is what it is.

+1 also they are very reliable engine.

ALRIGHT EVERYONE.

POST YOUR AVERAGE CITY/HIGHWAY MPG and how it compares to the previous cars you've owned :rolleyes::rolleyes:

Beleeve it or not, I got 22.25 MPG HIGHWAY on I-55 - STL to CHI n bak, ~575 miles w/4.36 final drive. :eek:
And this is calculated by the ole skool method, difference in mileage divided by gallons fueled, not the ECU guesstimate. LOL! The ECU stops displaying a range when ur close to empty anyway, how fok'n worthless nIssan! :thumbsdown:

Maybe it's just me but why buy a Z if you're worrying about the gas mileage. That's like complaining about the inability to rotate tires...

OP was not complaining about gas mileage, just made an observation and asked for an explanation.

Now onto his 2nd question. My prior car 04 G35 Coupe with auto trans, average 17, mostly city. Current Z is a 6mt with same type of driving, getting 16.5, was only about 15 until exhaust got changed.

:tiphat::tiphat:

Thank you for actually reading my post!

Damn! Acceleration must be brutal.

Previous, lets see. Toyota Paseo, never calculated, but easily 30+. Tiny lightweight car, tiny 4 Cyl.

'99 Accord, 29 MPG.

'09 370z, 23 MPG

'04 Cobra, 16 MPG

'12 Focus, 33 MPG

'14 370z, 22.5 MPG, so says the gauge. I need a tune!

OK...read the post...sure....easy...

V8s make more torque than Nissan V6s...therefore, their gearing can be made for interstate driving to = or beat V6 gearing MPG...It's all in the tranny/final drive ratios...

I drove my 09 from NY to FL avg mph 73.4 avg mpg 28.4

09 Sport with more than a few mods. I avg around 22 in town and on the highway was pushing 40mpg. That's if all hwy. As you can see my avg speed was ummm up there. Beats driving a Prius at any mpg.

My 05 Frontier Nismo gets 15.9 regardless. Same with 4wd or 2wd. Used to be 16.9 but got knocked slightly when I went to 17" wheels and BF Duratrack meaty tires. Still happy with that considering. Can't live in CO without a mountain/winter truck.

I get 90+ mpg if I go downhill and in neutral lol.....

In all seriousness I get 21 city and 25ish highway.
