MPG will improve over time. Mine is much better than it was a week ago -averageign @ 18 I was averaging @ 15

 

Like most Nissans seems like the difference between normaly city driving, and gentle freeway driving is enormous, in terms of MPG. I get about 17mpg in mixed city/freeway driving, but easily 25mpg doing a steady cruise on the freeway. Just seems like the MPG plumets once you dip even half-way into the pedal.

 

i'm getting about 18 19mpg right now granted i am still shifting only at 4k rpms still breaking in..

 

I'm at 2700miles. Going back and forth to work I average a solid 18. Last night I did a quick 45min freeway trip (45min there, 45min back). With the cruise control, I was getting around 26mpg at 65mph.

 

not too bad i guess....i was still hoping for better...like around 28mpg on hwy range

 

Gearing seems a bit excessive, but only in the higher gears. The lower gears seem comparable to most other cars. Comparing to my wifes TL....

Redline:
TL: 6800 Redline
G35: 7500 Redline

First gear @redline:
TL: ~45mph
G35: ~45mph

5th Gear RPMs at 70mph:
TL: ~1900
G35: ~3000

Granted my G will pull harder than my TL without needing to downshift, but my G still downshifts into 4th all the time anyway, so why not have 5th geared for better cruising and MPG? Our TL gets 30mpg@80mph. Nothing beats humming along @ 85mph/2300rpm.

 

What's the top speed on the TL?

I think (for some reason) Infiniti is concerned with achieving a 150-155mph top-speed. Car&Driver timed 0-155 in the 6MT G37S at 36 seconds. Maybe they are trying to "compete with bmw" ? That sort of high-end speed usually requires fairly evenly-spaced, aggressive gearing.

I'm guessing Acura is not as concerned with this...

 

I had never been able to get 20 MPG or more in my everyday driving:

60% - Smooth Highway
10% - Stop and Go Highway
30% - City

But i just took a long trip (300 mile one-way). On the way there, in a good amount of rain and avg speed of 80 mph i got 19.8 MPG

On the way back, in sunny conditions i got 20.9 MPG with an avg speed of 80 mph as well. However, i had about an extra hour of travel time here because of horrendous traffic in NY and NJ Turnpike. So when i wasn't stuck in traffic, i was doing at least 85mph.

Would love to see what i could get on a nice long drive in sunny weather with no traffic. My guess is ~25 mpg.

btw i have almost 6,000 miles on my G now.

 

Top speed on the TL is way up there too (150ish), BUT it will take much longer to get there.

Who drives at top speed?

Frustrating if that's why the G has such low gear ratios, only to achieve better marketing props. Meanwhile the rest of us cruise at 3500 rpms daily.

 

I agree. Or better yet, I wish they would just add another gear but leave 1-5/1-6 as-is.. keep their marketing props but give us a nice long cruising gear at the top.

 

I had an 04 TL 5AT
It pulled okay in 4th all the way to redline at approx. 105mph? (it's been a while) but when it shifted to 5th, the party was OVER! It seemed like it would have taken an awful long time to reach its top speed...

 

For the return trip, w/cruise control at 65mph (6mt), the computer said 27.7mpg for about 45miles.

 

That's the best I've seen yet, MT or AT.
