Old user, NEW CAR 2013 Subaru STi
 

Hey everybody,
i've been MIA from this forum for about a year, but i've still been waving the "ecomodding flag."

I've finally saved up enough money to buy my dream car 2013 World Rally Blue Subaru STi.

However, it's time to retire my old ecomodding project "AeroSol.

I know the STi is not known for MPG, but im always up for a challenge. Future eco mods include Scangauge II and weight savings. EPA estimates are 17 city and 23 highway with 20mpg combined. Long as i can AVERAGE 22-23 COMBINED mpg...i'll be happy.

I dont see many STi's on here, therefore, once i get a scanguage II, i plan on starting an "STI log" to document the effects of mpg based on the following:

1) base mpg (this will be really fun ;))
2) folding in side mirrors
3) mpg in "intelligent vs Sport mode vs Sport# mode"
4) does the adjustable Center Diffrential have an impact on mpg?
5) anything else i can think of

Hopefully this will be a useful reference for the tens of Sti owners out there wanting to get good MPG>

Anywho, i just wanted to show the new whip :)

I'd love to own an STi someday (or a Subaru in general), but I sure wish they were a bit more efficient.

sure they are efficient...the new imprezas and foresters can get 34mpg highway due to losing weight and cvt transmissions. Granted, 34mpg is nothing to get excited about in our Ecomodding community :p

HEY HEY HEY. There is nothing wrong with taking a dream car and maximizing performance (mpg)!

And being a standard, you can do a kill switch- mega mpg
You can close off most of your openings if you want- big mpg
(Although you lose the performance of a colder engine bay, you gain the aero benefits- to me this balance out, but utilizing a turbo for power, it may hurt your performance more than a NA vehicle)
After market should be huge- easy to get the boy racer parts that actually work.

Plus, lowered expectations yield higher performance by %. 39 mpg here is nothing for any Toyota, but for me it's 77% above EPA. You should be able to easily see highway mpg in the city, even having fun.

wow! i've noticed your last 3 tanks have jumped up to 37-39mpg...in a ROUCHE MUSTANG!

What do you think was the biggest contributor to your gains? kill switch?

it'll be interesting to see your mpg gains with the lower grill block installed.

Actually, the lower grille block was installed on

I got off my butt and did the lower after I was pulled over for not having a front tag, OSP gave me a letter so I could get out of it for a while, but they said they have to crack down more. So, I "adjusted" my plate to stay in the center. I am not doing images yet because my plate number is on it, but it will be visible soon.

Kill switch nets me 3-5, I am going with. It is WAY more useful in the warm air. I use it more sparingly, so if I can not coast a decent distance, I do not use it- I also speed carefully- 4 over in 45 mph or less, and 8 over in 55 mph or more, so my pulse and glide is rarely used, more so with hills- I am also very attentive of traffic, so if there are a lot of cars, or potential issues, I don't use it. In winter, the coast distances are considerably less.

This current tank, is the nicest tank I have ever driven. I have only revved my engine at three or four Camaros or challengers, and only 100% throttle zero to 70 redlined once.

It's amazing how easy 30 mpg was w/o a kill switch and having loud exhaust/fast accelerating, and how extremely difficult 40 mpg is with being very careful lol.

I guess kill switch is most of it, but its in combination with the warm weather improving my coasts- and less fuel needed to get up to speed to get to other coasts. I also have spent less time on the highway lately, and 70 mph WRECKS my fuel economy. As Ford proved, she loves the 40-50 mph range.
