Default What makes the LS1 get such good gas mileage?

This is assuming an M6. Here's my take.... 18-22 MPG is average for most cars (sedan, 2 door, sports). At least this is what i think is average (i could be completely off). The LS1 is a fairly large engine w/ 8 cylinders which i would ASSUME would gobble up fuel like mad w/ the amount of output it can create (and the way we often tend to drive it).... so why such good gas mileage and at the same time and still be a beast of a performance vehicle?

I mean, 22-25 MPG in the city seems amazing to me for such a powerful engine but 31 on the highway is a bit more believable due to the tall 6th gear. Any takes? Am i just that out of the loop when it comes to MPG and we actually DON'T get the good of mileage? Or is it true?

i have had my m6 z28 for about a week, and am averaging about 20mpg to the tank, but that is with romping on it a good bit, and some city driving

I have an auto and have averaged 31 mpg a few times (all highway). Mixed driving averages 22-28mpg

I'm fairly sure it's due to the tall gearing and aerodynamic shape

The car is very streamline has good gearing and lots of power so you never have to downshift even going up a huge hill in 6th with the ac on. It takes minimal power to keep it going and i am at like 1,400rpms at 65mph in 6th where a camry orsomething would be aroung 2,600 or so

It gets good gas mileage because of the power to weight ratio. It like putting a big motor on a skate board, its not going to use alot of fuel to move it.

In conjunction with double clutching of course...

I seafoam on a regular basis as well as keeping my engine tuned up and I get exceptional gas mileage...Thats my secret to success



Lack of mods might also play a factor

How the hell are you guys getting such good gas mileage?

I typically get 12.5 - 13.5mpg with 90% city driving. My car has really been sucking fuel for the past year. I used to get 18-19.5mpg 80% highway 20% city 2 years ago when I worked further away, but that still isn't nearly as high as you guys have been getting.

BTW, I have an A4 with 3.23 rear and I don't romp on it much.

My car with the turbo, hot cam, and 4.10's I would still get 26mpg on the highway, and about 16-18 in town depending on if i beat on it or not.

Powerful, yet efficient fuel injected engine, coupled with a moderately low weight, and and the right combination of gearing (6th gear + ring & pinion). I am thinking 6th gear is a 0.5 ratio, isn't it?

our motors were, "touched by God" and the gas mileage is just his work.
