Lexus IS riding on Corolla chassis???

Lexus IS riding on Corolla chassis???

Have anyone of you saw the new IS?, well guess what, its also a 9thgen Corolla chassis and RWDorAWD, 2.5-3.5L engine. I am guessing the older one has an 8th gen chassis. Tell me if its true? and its a pretty nice car for going into formal parties I'm buying the IS250 6spdMT rather than G35 even though it has more power.

i thought the new IS is riding on the GS chassis and extact same front end suspension components w/ the GS also....

its as short as the corolla9

the last body style was riding on a corolla chassies... well the 9th gen rolla was riding on the IS chassies... I don't know about the new one tho...

I assume the 9th gen rolla and the 1st gen IS don't share any suspension parts, though, right? They may be the same chassis, but that doesn't mean it would be easy to convert a 9th gen to RWD, just for anyone thinking about it.

I would love to know where you guys are getting this information, because it makes no sense...

suspention parts are diffrent than drive train parts... but yeah the 9th gen and IS are diffrent in everything except for chassies...

I used to work at a lexus dealership.. when I was bored I would read the tech manuals back in the shop...

Yeah, I realize the diff between suspension and drivetrain. Just making a comment.

sweet shit...

I'm going to say I don't believe it (either gen). Where did you get this information?

Lets get the list going that challenges that claim. The IS has a hump for the drive shaft, the drivetrain is not transverse, the IS has independent rear suspension, the IS is a slightly larger car. I honestly believe there is little chassis wise that is similar.

you guys are all wrong. the old IS rode on a modifiy supra platform on the old official altezza website. the new IS rides on the new Toyota Crown Platform along with the New GS. the 9th Corolla rides on the Vista Platform which is discontinue now. the New Corolla platform will be on the new Toyota Chassis

There you go.

The cars use the same 10,12,14,17mm bolts though, hahaha.

so are you saying that the tech manuals that the Lexus techs use to fix the cars is wrong too...

What are the chassis codes specified in the shop manual? Lets bust em' out.

The 9th gen Corolla is a ZZ(E) chassis (models 120-3,130,131). If im not mistaken the Previous Altezza/IS should be a SXE/GXE chassis while the Supra is a JZA chassis. I don't yet know the code for the new GS/IS which are said to share some underpinnings.

Toyota used the 9th gen chassis for the late Celica (ZZT) and a little for the MR-S (ZZW).

don't rember off the top of my head.. this was over a year ago... and in saying that.. I could also be wrong.. but as far as I rember they are the same chassis or VERY simaler...

no. toyota modifiy platform to suit each needs. for example the cressida is based off the supra platform along with the 1st gen IS. the Xb and Xa is based off the echo platform. each platform is made to accept certain engine. like the is, gs, cressida, supra, crown can use the 2jzgte motor. the echo platform can use any nz series platform and so on. but as far as manual toyota makes them model specific. even if they ride on the same chassis. the New IS shares many compoenets with the GS/Crown/Mark X.

yes exactly they are modifiy from the Vista Platform. therefore the chassis code is different.

Well, anything is possible, but I think theres too many differences in setup to make them too similar.

Toyota likes to share parts as much as they can without hurting the cars identities. Some chassis are different on powertrain equipment alone. The ZZ chassis uses 1zz and 2zz engines and the Supra uses a 2JZ engine (JZA chassis). Side-note, that doesn't apply to all of the codes

I don't think there's a possible way of the new IS riding in the new chassis seems kinda weird to me though but I dk might be true...

Ah I see... same ish chassis with mods... made to accept diffrent engines... ok...

the new IS rides on a new chassis. its stated by toyota in japan.

nm, im not going to bother. toyota has about 3 major platform. thats all i'm going to say. the IS is rwd so itll get a rwd platform the corolla is fwd so itll get on of the other two fwd platform. thats all im going to say.

well the IS300 chassis code would be JCE10, that mean the chassis is a (CE) not (E) like corollas

sooo.. some give me the gist of this thread. have anyone called bs yet?

I got called on... my info was in my heasd for a year and I was wrong...

SO ITS A GS THEN! and I actually raced one GS when I went to play golf last week its about the same size as the Corolla only wider and has I think a 4-6 inch longer wheelbase and ITS A FAST AS HELL LEXUS! he got me good.

AND IM AM REALLY GOING TO BUY THE NEW IS250 RWD6spdMT even though it sucks gas like the IS350
Because 350 only has a 6spdAT.and the only mod i would do when i buy it next year is the aluminum pedals and change the Exhaust to HKS or maybe it will be too loud.

Someone explain this to me..."chassis" "Unibody"

a chassis is basically the frame. like the AE/ZZE Corolla. it has an E chassis, the JZA/MA Supra has an A chassis, Aristo/GS has a S chassis, Mark II/Cressida has a X chassis. so they're all frame designation.

Unibody is the type of frame. all cars/suv like the highlander, Harrier/RX have a unitized body constuction which means its a one piece design.

Trucks and most heavy SUV like the 4runner, land crusier, tacoma have a nonunitzed body meaning that there are two frames bolted on.

Thank You, I understand what you're saying, but now I'm more confused about this thread as a whole.

We're just trying to see if the Corolla and the IS are based on the same basic structure. As far as I know they are not.

All you need to know is:
1) Cars use a unibody as their basic structure. The body and frame are one piece.

2) Trucks use a frame and then their bodies are put on top of that.

The picture below is of an old corvette, but old cars had a separate body and frame like modern trucks do. Notice how there's a frame that supports the suspension and drivetrain.



When you lower the body on top of that, you have your finished vehicle.
