    Why, according to the EPA, does the 2001 auto GT get better fuel mileage than a 2001 manual GT?

    2001 GT Auto: 29/36
    2001 GT Manual: 28/33

    sorry dude, your figures are wrong. check and you will see that GT Auto Gets 27/34 and GT manual get 28/34.

    I agree -- the car looks better without the spoiler, because the lines of the car are resolved without interference. It looks absolutely sharklike without the spoiler (and it's cheaper to boot!) If I were to add a spoiler, I'd add an aftermarket, adjustable spoiler like the prototype had.

    Most modern cars have ECUs that cut off the fuel supply when decellerating - meaning that you actually use less fuel when engine braking than when you kick it into neutral and let the engine idle. Switching your car out of overdrive in stop-and-go traffic will do two things: calm your nerves by not having to brake as often, and give you better mileage. That's why that little button is there!

    It's also great for setting your suspension for those 90-mph sweepers!

    It has to be realized that fuel injection is different from carburetors in this respect: Take your foot off of the gas. On a carbureted car, the engine will still suck a relatively large amount of gas in, based on the current rpm. On a fuel injected car, you take your foot off of the gas, all gas flow is cut off except for the amount needed to idle.

    Its been a while since I talked about carburetors, but I believe that is a reasonable synopsis.

    Just purchased my Celica GT. Got the 5 speed, with UP,AW,CF,CK,RF, and SR in
    Spectra Blue Mica for $20,000 out the door. I pick it up Wednesday. Can't wait!

    I'm thinking of getting 16" custom wheels with the Kumho ECSTA Supra 712 tires.
    Not sure whether to get them now, or wait a year and run the stock tires on the
    15" alloy wheels. (Probably comes with the Dunlop Sport 4000.) Ideas? Comments?

    What about getting a little more horsepower? Is the custom TRD air filter worth the extra bucks? Thanks!

  • denniswadedenniswade Posts: 362
    Any effect it has would be at the high end, and it might actually hurt you on the low end. Save your money.

    On the other hand, if you want to spend a little cash, get a little more power and a really neat exhaust note, get the TRD muffler -- it is sweetness personified, and it will halp you enjoy that wonderful engine as you're winding it to redline.
  • jk111jk111 Posts: 125
    spoiler is useless on a celica anyways. The new agressive spoiler I talked about is at least twice as high as the current OEM spoiler, maybe a good 7 inches off the back.. reminds me of the supra spoiler some what.
  • alex18talex18t Posts: 117
    isnt the change with a K&N so small with loss of low and and gain of high the you barely notice it? i can understand an inatake and exhaust, but you think an airfilter will have real affects? I'm not callin you a liar or anything of the kind, i'm just wondering since i put a K&N in my car and felt no difference either way.

    and you bought your celi with no spoiler? that's awesome. they dont have any cars at the dealers without spoilers where i am. i probably would have opted for no spoiler had i seen one with and without side by side. the pictures look so good without it. looks more mature and less boy racer-ish. maybe when i get some expendable money in the future i'll treat myself with a repaint and spoiler removal.

    It was darned difficult to find a Celica without a spoiler. I have never seen another one without, except for my own.

  • gambit293gambit293 Posts: 406
    I don't know who's right or wrong, but I got my numbers from the EPA website (

    Furthermore, I noticed these figures in a dealer lot, on those spec-sheets they have on the windows. I was looking at a manual and auto right next to each other. I asked the dealer why the auto had better mileage than stick; she had no idea.

    Could be that the EPA messed up on their website.
  • sergeissergeis Posts: 134
    I don't have spoiler on my GT. I actually wanted a spoiler, but all they had with spoiler were GTS.

    denniswade - the engine braking may be saves gas if you actually _want_ braking. If you have a slight slope through which your car could simply roll in neutral at ~constant speed - then switching to neutral saves gas, the difference is just too big to be accidental (30 instead of 25 mpg). This time I am changing driving habit - accelerating as hard as I wish, but still switching to neutral when I get to cruising speed and there is a slope.

    BTW, how does swithing OD off save gas at stop sign? It is in the first gear anyway.
  • coupe2001coupe2001 Posts: 100
    we have the same car, i added 17" wheels with 215/45 tires, TRD exhaust, and K&N filter. I'm not sure about performance gains cause i added this stuff at 500 miles on the odometer, and didn't push the car to redline till 3000, but im getting killer gas mileage on 87 octane. I've posted great number before, but my last highway trip was 36.8 MPG (211 miles on 5.72 gallons). I cruised between 65 and 75 mph on and off interstates. My tires are slightly taller than stock.
  • 1kgwxman1kgwxman Posts: 9
    Thanks for the info. I decided on 16" wheels with 205/50/16 Kumho Supra 712's.
    I'll give up a little performance for a bit less jarring ride. (So many potholes in Michigan.)

    If I add the TRD exhaust, I think I'll just wait until the first muffler/tailpipe goes.

    I doubt I'll get that kind of gas mileage. I usually cruise between 75-85 mph depending
    on traffic.

    Thinking of adding those HID Xenon headlights/brights/fogs. Anyone else install them?
  • dimitardimitar Posts: 4
    I have noticed the same thing - very good highway mileage, but poor city mileage.
    I have the GT manual and I get 23-24mpg for pure city driving - lot's of stop & go - pretty much from first to third gear and back again.
    And yes, it really helps if you cruise in neutral.
    Plus this way you don't have to worry about clutch etc, just breaking. Pretty cool.
    By the way, what is the considered breakin time for the Celica?
    Mine still has only 500 miles on it and I can't wait to be able to drive it without worrying about the engine.
  • denniswadedenniswade Posts: 362
    You are exactly right -- the loss of low end and gain at high end is so negligible, the only benefit is the appearance when you lift you hood. If that makes you happy, go for it!

    And unfortunately, no -- my wife's car does have the spoiler. She wanted it and it's her car. I would've saved the money and liked it better without it.
  • alex18talex18t Posts: 117
    yea the K&N made me bond with my car a little. lol

    i put in some 100W eaglite xenon bulbs in my hi, lo, and fogs. they look pretty good and did increase my vision a little on very dark roads. i had them for about a week or 2 now so i cant tell you how long they last. kinda annoying to install them though. especially the fog lights. if they blow i'll replace them once and if i get another dud i will just put the stock bulbs back in. no important difference in vision, i'll just lose that bluish-ness. One kinda cool thing i noticed was the my head light assembly is blue durring the daytime when you look at it from the front because of the blue high beam bulb reflecting off the inside of the headlight. pretty cool looking on my carbon blue car. i bought some xenon parking light bulbs that should be hear next week to complete the whole xenon look of the car at night. I'll let you know if my headlights melt and turn brown. i dont want to think of the bill for that. i think that kind of stuff is rare though.
  • alex18talex18t Posts: 117
    do any of you get a lot of valve tick from your engine? i can hear plenty from inside the car. is it normal? what causes it?
  • 1kgwxman1kgwxman Posts: 9
    Good luck with the HID lights, Alex.
    Funny, I remember a pinball machine from the 1980's called, "XENON". lol!
  • sergeissergeis Posts: 134
    1kgwxman, how did you measure 5.72 gallons with such precision? If you just filled a full tank, then it was easy to get it wrong by 1/2 gallon, add it to your number and you get 34 mpg. Or subtract and get even better mpg. I got 34-35 on a high way trip ~600 miles long - which for 0.5 gallon precision gives 34.5 plus-minus 1 mpg (at 72-80 mph). I wasn't impressed, I get 26.5 mpg on Grand Marquis, which is almost twice heavier and has 8 cylinders. The manual states that GT can do up to 40 mpg, 34 being average for highway. The cartest program also predicts 40 mpg for Celica (highway). And for larger wheels it predicts 2.2 mpg more, which is about the gain you actually saw. The bigger wheels must give you better economy, but they also must slow your 0-60 down by few tens of a second.
  • alex18talex18t Posts: 117
    the valves on the 1zzfe, are they controlled by mechanical or hydraulic components?
  • gambit293gambit293 Posts: 406
    I'm the proud owner of a 2000 Black GT-S. I only got it around a month ago, and it still has less than 2000 miles on it.

    However, I'm still new with stick. And I'm not used to high-reving engines like the Celica's. Furthermore, the Celica's engine is really loud; I'm not used to that also.

    I have enough experience that I don't stall as often any more, but I'm still slower than I'd like, especially driving from a stop. Consequently, I often find myself lagging behind slower cars and lots of (what I assume are) automatics.

    What speeds (or RPM) do you all normally shift at? When starting from a stoplight, are you normally in 2nd by the time you're past the intersection? I'm talking about in "routine" driving; I'm certainly not good enough to try to race anyone.
  • coupe2001coupe2001 Posts: 100
    i just filled the tank like everybody else does to compute mpg. I question the half a gallon difference. Pretty sure it allot more accurate than that.

    The Celica Owners Manual doesn't list EPA predicted MPG. Why you ask? Because the owners manual is for all of the Celica models. It doesn't know which model you have. I checked it as well and couldn't find anything on EPA MPG. Please tell me which page it's on.

    I can definitely tell you that it's not 40 MPG highway.

    WWW.TOYOTA.COM says EPA MPG for Celica 5 speed is 34 MPG. My window sticker says 33 MPG HIGHWAY. It is nowhere near 40 MPG.

    You say that larger tires account for 2.2 MPG more. That's crazy! By comparison the stock tire has 819 revolutions per mile, why my size has 838 revolutions. 19 extra revolutions per mile doesn't equal 2.2 miles. In fact, it's considerably less than 1 mile.

    Your automatic GT is rated the same for EPA HIGHWAY 34 MPG. congratulations! you are getting the EPA number.

    I question the slower 0 to 60 as well. My tires may be slightly taller, but they grip better than stock which is needed with a 5 speed.

    My setup (K&N, TRD, 17" wheels) is great for MPG and Performance. I know it would take any automatic GT, and be door to door with any stock auto GT-S.

    Hi, Coupe2001,

    Hey, I figured that I would argue with you here, too. ;)

    Actually, I just have some questions about what you said in your last post. You mention that your tires make more revolutions per mile (RpM (to avoid confusion with RPM (revolutions per minute))) than stock, but you also say that your tire is taller. If your tire makes more RpM, wouldn't that mean your total tire size (rim + tire) is smaller than stock?

    A smaller tire will increase acceleration and a larger tire will decrease acceleration (as long as all other variables (i.e. wheel weight) remain the same). The reason for this is because when you change the tire size, you change the effective gearing (i.e. the amount of times that the engine rotates to cause the wheel to rotate). To provide an exaggerated example, let's say that you put tires on that are half the size. As you accelerate, the torque sent to the street is effectively doubled (because the engine spins twice as much to move the car the same distance), but you have to shift gears when you are going only half as fast (because the engine spins twice as much to move the same distance :)). Additionally, if you incorrectly assume that the speedometer is still correct, the acceleration would seem even faster since it would read 60 mph even though you are only traveling 30 mph.

    Of course, that being said, for most sensible tire size changes, the difference in acceleration would be negligible, and may even be worse due to other factors (that I was ignoring above) like the wheels being heavier, rotational inertia being greater, etc. Also, 0-60 times wouldn't change significantly because you would have to shift gears more often to get to the same speed.

    This would affect actual MPG as well. Since the engine would have to rev higher to maintain the same speed, actual MPG would decrease with smaller tires. Apparent MPG might not change, though, because the miles measured on the odometer would be greater than the actual miles traveled, so when you do the calculation (miles/gallons) the artificially inflated mileage would increase the apparent MPG, even if the actual MPG is less.

    So, in conclusion, I have, um, proved that I am full of it. Heh. The different tire size does affect acceleration and gas mileage, but not significantly enough to care about.

    Sorry for wasting your time. :)

    I just got my 2001 Celica GT. Overall, I'm very happy with my purchase.
    A few niggling things like some scratch marks on the rubber trim around the windows will be taken care of, since the vehicle was delivered from a different dealer in Ohio, who had the car on their lot for much of the winter. (Car was built 12/00.) I suspect when the car was brushed off from snow or ice, that these marks popped up.

    I'm eager to press the gas pedal, but for now will baby the vehicle for the first 2000 miles.
    Will suck on the highway, since the dealer said I should stay below 3,000 RPM and 60 mph.

    One thing I did notice which Toyota Motors should remedy, is the cheesy cheap plastic dash.
    My old '89 Corolla had a nicer one. Toyota should replace it with something a bit more
    classy. On the plus side, I've already seen heads turn, especially from younger drivers.

    All in all, I think I'm going to enjoy this one!
  • denniswadedenniswade Posts: 362
    The GT-S has VVTLi technology that kicks in hard at about 6000 rpm - redline for most cars, but the point at which the GT-S engine starts to really make power.

    Don't be afraid to rev the engine, even while you're breaking it in -- just don't hammer on the thing for the first 500 miles or so. After that, feel free to abuse it -- it's made for it, and it's the only way you'll get the power out of it.

    Also, learn to shift with a light touch, so you feel the gates. It's not a Mopar with a Hurst shifter, and if you muscle it, you can wind up grabbing the wrong gear and zing the engine or the gearbox.

    It's a great car that deserves your attention and respect. Driven properly, it will reward you way beyond your expectations.
  • sergeissergeis Posts: 134
    coupe2001, I was confused - thought your wheel+tire were taller than stock. Since they are almost the same size (2% smaller), then there should be no difference in 0-60, unless you let them slip (with auto it is almost impossible), then you get some gain from better grip. I would still put considerable error margin for your mpg, especially if you filled your tank using different pumps. I am not saying your mpg is worse than you estimated, it might be also better. It is just that when I saw your precise 5.72 gallons I expected that you used some sophisticated measurement method. I can fill my tank at one station, and then drive a mile to the next and get another half a gallon in, but it does not mean my car makes 2 mpg.

    Indeed, Celica's manual does not have 40 mpg - sorry - it was on the sticker of my GT - it gives big numbers 27 and 34 mpg, and then below something like:

    ...results reported to EPA indicate that the majority of vehicles with these estimates will achieve between
    28-40 mpg (highway)
    22-32 mpg (city)

    Text was in small letters, numbers were bigger.
    Better numbers (40/32) are there to make you happy, the lower limit (28/22) is there to make them not responsible if your car does not live up to your expectations.
  • coupe2001coupe2001 Posts: 100
    i got the numbers backwards. my car tire is 819 revolutions per mile and stock is 838 revolutions per mile. that would give my tire a slight advantage. i used the tire calculator at
  • coupe2001coupe2001 Posts: 100
    yeah, i know that i can drive to a gas station even 50 yards away and get more gas in the tank, even a 1/2 gallon. The term is called "topping it off". I never do that. When the pump shuts off, im done pumping. simple as that.
  • gambit293gambit293 Posts: 406
    Thanks for the tips. I've seen your postings around the Townhall, and your technical knowhow is impressive.

    I've already mishifted before, though not recently. Also, I was going pretty slow, so I don't think it did too much damage.

    Do you routinely take off in 1st gear in the 6000 rpm range? I guess I'm trying to get a sense of scale. Right now I either wonder if I'm staying in low gears too long, and thus straining the engine; or else I wonder if I'm shifting up too fast and thus wasting the potential power range. Most people say, "You can tell when to shift when the engine gets loud," though I assume this applies differently to the celica's loud engine.
  • guitarzanguitarzan OhioPosts: 759
    Average shifting: Shift at 3500. Going up a hill, shift at 4000. Down a hill, 3000. That's your daily driving. Having lots of fun? Take it to redline, it won't hurt.
