Hi CL,

While me and one of my colleague were talking he told me that the Lexus IS was on a Toyota Corolla frame. I didn't know if this was true so I didn't comment but I am now curious if this is true? Does anyone know? Is the Corolla a water down IS like how people say the Camry is a water down ES?

 

Been discussions on this already, the IS is based on the GS platform, those who say its an upgraded Corolla don't know what they are talking about

 

Hence why the GS is always released before the IS

 

NOT a corolla frame. That person has NO idea what they are talking about.

Like the others have said - IS is based of the GS ...

 

had the same argument with my co-worker that drives a jaguar. about the platform then went on about the layout, he thought the IS and most Lexus cars were front wheel drive.

 

The IS and GS are based off the awesome RWD Toyota Mark X in Japan. Tell your colleague to go read a book

 

The Corolla shares about the least with the IS of any car in Toyota's lineup. They are in no way similar, other than being about the same size.

Funniest thing I heard today.

 

the chassis code of the two is different...

 

Lol!! Yes, and QC and manufacturing process is between a Lexus and Toyota is different!

 

That doesn't necessarily mean they aren't common designs though. The IS/GS/LS/Mark X, etc. all have different chassis codes, even though they share a lot in common. (For example).

Gotta laugh at the dummies that think the ES is a re-badged Camry like the Cavalier / Sunfire. Starting out on the same platform is miles away from being a re-badge.

 

IS actually is on a Tacoma frame, true story

 

Thanks for the reply. Does anyone have a link to this that I could read up on?

 

A link talking about the differences in design between a Corolla and an IS? Not really, no. You'd have to research the suspension and frame designs of both models, but a few quick points:

In a Corolla the engine is mounted transversely (sideways), IS is longitudinally mounted (lengthwise).
Corolla is front wheel drive, IS is rear wheel drive (or AWD with a transfer case mounted behind the transmission).
Corolla front suspension is a McPherson strut setup, IS uses a double wishbone design.
Corolla rear suspension is a torsion-bar semi-independent axle beam, IS uses a multilink independent rear suspension.

Other than things like switches and bolts, they share nothing in common. I can post some diagrams and dimensional differences if you'd like.
