so don’t write it off as less than GR Yaris.
It absolutely is less than the GR Yaris. Period. Clearly you don't know the entire story of the GR Yaris?
They started with their Rally car program and built it into a street car. HUGE difference. It's pretty crazy what they did, actually. It's also not built on the Yaris line. It's built on a GR Yaris-only line that was built (from scratch) for the purpose.
This will be an off the shelf Corolla made into a "rally" car.
But yea....with ~300HP, 6 speed manual and AWD...it would still be a hoot! I'm definitely not saying it won't be fun.
But the GR Yaris is special.
