So I've been looking at videos and reading barely understandable auto-generated translations.
There are two things that have stuck out so far, and neither will probably surprise anyone.
1 - The GR86/BRZ have different clutch engagement or accelerator pedal feel.
2 - The GR86 has been been made to oversteer a lot.
Its the second one I'm a bit more worried about - because its not like the BRZ seems unable to kick its read out, it just seems like the GR86 is willing to lose it with very little power.
While I do think that the current model BRZ/86 on performance tires needs more power, particularly the BRZ, I don't think either will need to tune more oversteer now that it has more power.
edit - was watching this one posted earlier.
Now it might well just be tires (I think I made out the word *edit goodyear* while one guy was riding in the GR86), or I might just be seeing things and thinking that 'sex party with still stiffness' means something entirely different.
I'd love it if anyone who might speak Japanese can give us a summary of what's being said about the driving differences...
