370z MPG VS V8

DIGItonium · 07-21-2014, 10:20 AM

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.

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.

Good post. Personally, I prefer the shorter gearing for the Z as it's a mountain/twisties kind of car more so vs the other two. So giving up a few mpg's on the highway has never been a concern for me.

Wait a minute, I live on a frickin island.....what's a highway??

The point of this thread wasn't to worry about MPG..

I had an 04' S4 that only got around 16 MPG combined, and I loved every second of it.

I was just making an interesting observation how certain V8 cars manage to get the same if not better MPG than the Z. Simple as that.

I think you don't know us very well if you did not fully expect this thread to wander off into the hinterlands of non-sequitors and random observations.

You'll learn over time.

Yeah I guess I should have figured anything to do with MPG is a dangerous topic..
