rear anti sway bar = better mileage?

[Lewis]

Put on the rear bar for better road holding - but as I'm driving I feel the bar is also helping my mileage. I can get around turns with less understeer scrubbing off speed- thereby needing less acceleration to get back up to speed on the next straight - thereby saving energy IMO.

What a nice little extra- maybe the bar will pay for itself during the life of the car!:smile:

[auxmike]

This was the first extra I bought for the car. The car is real tight now on turns. Too bad it was'nt made standard.
I also added the TRD exhaust, another worthy addition.....:thumbup:

um..........................no.

if anything, it is allowing you to drive more aggresively=worse mileage. im not saying it is a bad addition. the yaris is decidedly a poor handler through turns with all the body roll, so im sure its worth it for that alone.

[guzziknight]

I guess it's all a matter of perspective. I came out of a Civic Sedan, prior to that a PT Cruiser, and the Yaris S Sedan I got handles far better than either one of those, even without the sway bar, which is my next purchase for the car.

maybe it does help a little, like conserving cars momentum through a turn instead of loosing speed to get the turn in. Lol a good excuse to have it on my mods list.

[JBIZZ]

Most mods = better gas mileage

:laugh:

yeah, like wider, stickier rubber, right?

turbos/superchargers give you better mpgs :laugh:

yeah, if you stay out of boost... :confused:

[supmet]

The logic is sound. I'd be surprised if you even saw one extra mpg from this, and unless you know what your doing with alignment and tires you're gonna pay out much more in tires than your saving in not having to accelerate. But that's pretty much on par for most hypermiling techniques :D

[Lewis]

I should add that I'm 62 years old and that I wanted the antisway bar for increased stability, not faster speeds through turns. So I really do think it's saving gas because to feel the same level of confidence (stability) on a turn, I need to slow down less, thereby saving momentum and gas in needing to accelerate less to regain my speed. Sure if you use the bar to drive more aggressively it will end up causing you to use more gas but that it's me at 62 years old.

Lewis:

At 62 years of age should you still be driving? :biggrin:

Just messin' with ya. I turned 60 yesterday, and it blows my mind that I am really that old.

sure beats the alternative Tom

That's what they say, Lewis. :smile:

Hmmm...got me thinking about throwing one on.

[Tamago]

this thread actually carries credibility in y'all's eyes?


























bbbbbbbbbwwwwwwwwwwwwwwwwaaaahahahahahahahahah













that being said, rear swaybar is a good mod. but srrsly? for mileage? lol

[JBIZZ]

:laugh:

yeah, like wider, stickier rubber, right?

lol, no like lightweight pulley kit, aluminum flywheel, CAI/SRI, axle-back muffler, lighter wheels, torque dampener, tighter/lighter springs (for less hobby-horsing), weight reduction, Maybe even a Limited slip differential.

The lightweight NST pulley kit brought my MPGs from @ 30 to 35

[Tamago]

your lighter wheels will have to wear stock-sized tires to help with fuel mileage. which means your yaris will now look silly as all hell.

True. I've currently got the 7-spoke toyota alloys & have no clue what they weigh. I'd like to upgrade in the future though.

[Tamago]

i see ur local to my shop. you interested in hub spacers with free installation?

Possibly, What I really want is a turbo!

[JBIZZ]

Awesome! How much would a turbo set up like yours run me? Do you have a business shop or are you a hobbyist?

[cali yaris]

^ LOL.

He has a turbo kit he was running successfully on his xA. Now he's selling it - it would require some modifications but probably would work just fine on a Yaris.

He makes stuff, sometimes designs stuff (::cough cough:: paddle shifter), and is super knowledgable -- and regularly arrogant. An asset to the forum... most of the time.

How'd I do? :biggrin:

[uncleyaris]

the topic, Sway = road hugging, not gas savings

[blazing blue]

I thouht the torsion bar eliminated the need for a sway bar...correct me if im wrong.

[koala286]

so i just want to make sure here i was thinking of ordering a sway bar for my gf's new yaris.

so no yaris comes with a rear anti-sway bar? this seems rediculous to me as its not a truck and belongs on the road only.

so if i get one any recommendation for brand? TRD, Hellwig... what do you guys think?

[Morgan]

there are lots of threads here... check out the TRD bar, its cheap, easy to install and does a pretty good job - but I'm slightly biased. There are other brands just use the search tool :smile:

[Loren]

FWIW, my first reaction was "huh?"... but, IF the OP is making use of the improved handling offered by a rear swaybar by simply carrying speed through turns, thereby slowing down less and having to accelerate less... there IS potential for improved MPG.

Odds are, you could do the same thing WITHOUT the rear bar, just with more body roll and less confidence. You really don't get into an understeer condition unless you're dive-bombing a turn way too fast or trying to accelerate too hard through the turn... conditions that a conscientious hypermiler would never put themselves in, anyway.

[2+2]

So, is your mission to convince your significant other that it's a good investment that will pay dividends with fuel savings?

I'll cosign. Sure, sure, you'll save tons of money and the fact that the car is more fun to drive is just a coincidence. :thumbup:

[Loren]

Heh. The average person drives about 10k miles per year. If we assume that the Yaris is capable of 40 mpg (it is) and that adding a rear swaybar, one can carry more momentum through turns and potentially gain 2 mpg (not likely, but it's a number... let's roll with it), then you're using about 5% less fuel. If we further assume that fuel costs are $2.50/gallon... that average person will save about $30/year by installing a rear swaybar and taking corners more "briskly".

So... in theory, maybe you could recoup the money in 4 years. :wink:

[BailOut]

Just like nearly every other "fuel saver mod", even if it manages to save some fuel it will be such a small amount that it would never cover the cost of the mod itself, nor be enough to offset the resources and energy used to create, ship and install the mod.

I suppose the same could be said of the entire vehicle as well. :iono:

Don't know how much increased tire wear would cut into that, with or without a sway bar.

[Lewis]

When I started this thread I thought to myself - could it?- it seems to help me hold my speed with less throttle through turns which should in theory result in better mpg. But be assured I got the bar to actually reform our medical system. I was getting a weak stomach from all the leaning and pitching from the stock Yaris- the rear bar really cleared it up. So now President Obama- you really don't have to do that health care reform thing you've been working on- my Yaris rear sway bar solved both that pesky energy situaion AND our health care crisis!

Next - getting my rear sway bar to solve global warming and to cure cancer..........stay tuned!

Might be the best mod of the century :-)

[Loren]

I'm convinced.

[docB]

What sway bar did you add Lweis? I leased this car so anything I would add needs to come off easily.

[advocate]

All sway bars install the same and in under 10 minutes by a knowledgeable person. The thicker the bar the more roll resistance that is added. But obviously for you hypermilers, thicker = weights more = slightly less MPG. So take it for what it's worth.

There are 19mm, 22mm, and 23mm swaybars for the Yaris.

[cali yaris]

There are only 19mm and 23mm as far as I know. TRD is 19mm.

UR 19mm = 12 pounds
UR 23mm = 15 pounds

[why?]

Ouch!!! So much for getting one of those.

[Loren]

Conventional wisdom says that a Yaris loses about 1mpg for every 100 pounds that is added to it. So, a 12 pound swaybar would maybe take away .12 mpg.

Honestly, I do think that slowing down less for turns (that you'll be able to do more confidently after adding the swaybar) would make AT LEAST that much of a difference.

[why?]

You are right for normal peoples, and if i were to even think about any type of racing it would prolly be a must add. But I am kinda nuts, and am planning on removing the rear interior pieces for weight reduction soon. Just a bit lazy, lol.

As for corner confidence, I love that rear end stepping out, that stuff is just fun. Drifting is my type of entertainment. Speed up into the corners, don't slow down!

lol losing control because you're too fast into a corner and you hit the grass is kinda nuts. I need to learn more about drifting.
