370z MPG VS V8
 

I have been doing some searching on this forum on people's average MPG's, and it seems like the usual is anywhere between 21-24. This just seems strange because I see pictures/forums of people in cars like the V8 ford mustang's who can average up to 25 MPG on the freeway, and it has a bigger engine than the Z.

This just doesn't seem to make much sense. Does anyone have an explanation for this?

does the cylinders shut down on the stang's v8 like on the vettes?

maybe that's how they're doing it? not sure.
i never really cared about mpg on my Z.

Why are you comparing average MPG of the 370z to the Highway MPG of the Mustang? Compare highway to highway. EPA MPG of 370Z is 19-26, 22 combined. Mustang V8 is 18-25, 20 combined. So it really doesn't get better mileage.

i drive mine hard and also in a bit of traffic daily. plus drag strip runs here and there and my avg. MPG is 19. that is amazing for the way i drive and also the fact that i am not on the highway that often.

I was just saying that it seems like most people average 24 ish on the HWY in their Z and some people with V8's get almost the same if not better.

Just an interesting observation I thought

There are several factors such as drag, power to weight ratio, gearing, etc. With the V8, I'm assuming such cars benefit with taller gearing. Our cars have shorter gearing for faster acceleration, but it sacrifices a bit of mileage. I'm only speaking off the top of my head so don't quote me lol.

Anyhow, I'm pushing at least 450 whp and my average combined MPG is around 22. :)

Lies i get 14.1mpg.

solution: driver mod :tiphat:

In my opinion, worrying about mpg when driving a sports car is sort of like worrying about rearranging the deck chairs as the Titanic is sinking. It is pointless.

:bowrofl: (i mean no disrespect to the people that passed away)

The modern V8 takes the MPG test well. I wonder if I could drive to get this type of result? Nope. Never.

what? is it still "too soon" for a titanic joke?

:shakes head:

:icon17:

Oh yeah.

Our car: ~2400rpm 6th gear @65mph
Stang GT500: ~1300rpm 6th gear @65mph
Vette: ~1400rpm 6th gear @65mph

My pop's C6 can get dang near 30mpg at a steady 65mph cruise (not that any of these cars are usually cruised at 65).

I think the 370 could use a taller 6th, it certainly has the torque.

I guess this happens because people buy V8 Mustangs and then putt down the highway in 6th gear at 55 mph getting 25 MPG. The Z definitely gets better mileage than a Mustang GT driven in a likewise manner.
