The normal corolla does not have a turbo at all. Besides the turbo, the GR Corolla has a completely different engine, different transmission, all wheel drive, limited slip transaxle and differential, and completely different suspension.

They should not have called it a Corolla at all. It's nothing like a Corolla.

> Corrola

Corolla.

And I suspect Toyota put a little more effort than that into the GR.
