How many rpms does your FRS idle at ?

I never go past 3k rpms.

So many thanks

Ok, but that didn't answer my other questions. How long are your trips (is the engine getting fully warmed up for most of the trip, or are they short trips done mostly with the engine cold)? Also, when you say city driving, how fast are you going most of the time? Lots of speeding up and slowing down, or fairly constant speed? Finally, what kind of fuel consumption are you seeing out of your Celica? That was also a pretty efficient car, with half the horsepower and 500 pounds less weight than the GT-86, so it isn't actually surprising that it would be getting similar (or slightly better) gas mileage. I wouldn't expect it to get wildly better gas mileage though.

Also, you have a manual, right? You say you are short shifting it, but how much gas are you using? It can actually use quite a bit of gas to be flooring it while lugging the engine - it's better to let it rev a bit more (3500-4k) and use 60-70% throttle if that's what you're doing. That having been said, if all of your driving is in the city (and especially if it is primarily short trips), you will get bad gas mileage. There's really no way around it (and pretty much any other modern car would be similar, except perhaps a hybrid).

dssence - Ummm..... You DO know that you have a mileage calculator built into the car right?

Change the settings on the dash and quit trying to calculate it using the fuel gauge.
Or better yet, get a droid phone, an OBDII bluetooth module and the "torque" app, and it will track all of that for you.

To complain about the gas mileage in a sports car of this caliber that gets greater than 30MPG is asinine.

Maybe you should buy a prius.
At least you would still have the same tires.

So you say it's better to keep it over 3500 but less than 4k? I'm most of the time below 3k, check what I said to vincent. About driving habit.

I know about the dash calculator built in . And no when I bought this car I bought it cause it was my dream car come true in all it's glory. I didn't think about being cheap on fuel nor anything like that. But having an old car like a 1979 celica liftback being more efficient than this car it quite not acceptable for me ( I know I know it's doesn't weight that much and everytinhg). You may agree or not with my posture but that my thought.
I wasn't looking for the greatest car on efficiency terms like a prius. But it never came to my thought I would be going through this tedious issue.

You don't need to do many kilometers. You just need to have the car warmed up and get to cruising speed.

Like the other poster suggested change your display to show mileage and you will know right away if there is a problem.

As an example, if I am cruising at 120 km/h my mileage is around 7l/100km assuming I'm not passing or going up a hill. However, when I am stuck in a traffic jam averaging 5km/h and barely getting out of first gear I get 13l/100km or worse.

By the way I saw a video on youtube with a guy , with some sort of external lcd display showing some information about gallons left digitally. I assume that was connected to the OBD port.
So what's the best OBD bluetooth device , and OBD usb . ?links from amazon to avoid buying something crappy.

I don't have cruise control on my toyota 86 FT. BUt I do understand your principle, take it to a cruising speed value.. and keep it like that.

It all depends - you're probably best off keeping revs under 3k or so and only using 50-70% throttle, but that may not accelerate fast enough in the city. If you have to accelerate a bit faster than that would give, I would say revving it up a bit more (as I said, 3.5-4k) would be preferable to flooring it while you're lugging the engine at 2.5k.

Also, you will probably get slightly improved mileage as it breaks in, but I wouldn't expect it to be a magic cure-all or anything. The reality is, you're driving in the city. You won't get good gas mileage (and you still never answered my question about the length of your trips).

Sorry about hte length of the trips.. now that much 10k , 20km not that much . short trips.

That hurts your mileage too then - the engine is spending a lot of its time cold, where it isn't very efficient. It also could explain why you're getting better mileage out of your Celica - I would bet that it warms up faster, so it's spending more of its time up to temperature, which really helps efficiency.

No way the engine it's warmed up before I go out with my car. In fact it revs and does the automatic warming and then sits at the normal idle value and keeps idling there.

What's a km?

Wait - are you starting the car and letting it idle until it warms up before you drive it?
