What other cars are there, like the EVO besides the sti, mazada speed??
Will a tune help the mpgs?

 

The R32 gets 18/23. The STI and Speed6 are also similar in mpg. The S4 sedan is 13/20. A 335xi is 16/25. The Evo is right in the middle of all these cars.

As far as will a tune help, that's well beyond my abilities

 

lol, I though I was looking at a damn SUV sticker.

 

remember those are based on the new mileage rating system. Most cars went down in rated mpg, even if they where the same mpg as last year.

"Toyota's Prius hybrid saw a dramatic decline, too. Under the new system, the 2007 Prius gets 48 mpg in city driving and 45 mpg on the highway. Previously, the EPA said the Prius returned 60 mpg in city driving and 51 mpg on the highway. Toyota noted that mileage ratings for competing vehicles will drop, too. "

It probably gets much better real world mileage if you use the cruise and do mostly highway. My IX MR gets 28mpg when I'm doing all freeway, and that's significantly better than what it was originally rated for The new 2008 ratings are slightly artificially low since they are now accounting for more aggressive driving that most people do now-a-days. In 2006 numbers the X would probably be rated more like 18/25 or so. Bah! Razorlab beat me to it.

The MR should have much better ratings than the GSR (6-speed, plus the DSG-type transmission) probably no less than 17/24 and maybe a tad more on the new ratings.

A tune will also help since all turbo engines are run rich from the factory to keep them from "blowing up". Everyone knows you can lean them out a bit safely and eek more gas mileage out (plus get better performance!).

Stripping weight will always help too.

Don't they test these ratings with a car full of passengers?

 

i'm sure the 14/20 mpg rating (under the new system) on the Evo 8 and 9's don't bother the owners.

This article is from 12-12-07, but it states that the GSR gets 16/22 & the MR gets 17/22. Woo Hoo! 1 MPG better!

 

it does, since a 7.0L 505 hp Z06 vette is better... gtr should br similar....

coefficent of drag is high, doest help

 

Meh I could care less about Milage I get on my X... I bought it to have fun on the way to and from work and everywhere else enbetween. Gas it meant to be burned!

 

Pretty much agreed. If you want gas mileage, get a car built for gas mileage like a smart car or a fit. otherwise step on the gas and drive the damn car like you have a pair.

 

You are considering a 30k-40k performance car and care about the price of gas? You have to be f'in kidding me. My truck gets 9 around town for the average, 16 on the freeway and I couldn't give a **** about the price of gas. If you can't afford it why even consider it? AWD, Heavy, small motor lots of power, there's a huge list of why the gas mileage is what it is, it shouldn't be better and as MANY have pointed out similar cars get around the same.

 

I'm glad I'm not the only one who knows this. Given the posts in this thread and the fact people continue to whine about the "less efficient" X it may take a few years for people to understand this...

 

+1 to bfdd.

 

A tune did improve the mileage on my Evo VIII quite a bit, so there is no reason it couldn't help with the X. The real area for improvement would be at those partial throttle and small boost builds that are currently running the car really rich. 9:1 AFR's are kind of ridiculous imho, but we will eventually be able to get this tuned out. Well hopefully.

Other then that, I have been using the trip computer to track current MPG estimates and adjusting driving habits accordingly. Ive been able to average around 28 on the hwy, but you have to not mind losing speed going up a hill Its kind of a little mini meta game while driving.
