Was this the performance upgrade that Akio Toyoda wanted from the GR86? When your look at the GR86's horsepower numbers to the BRZ's there's a 4 horsepower difference in favor of the GR86.

Toyota GR86 - 232 horsepower (235 metric hp)
Subaru BRZ - 228 horsepower

No, its not what you think.

In Japan the BRZ and GR86 are both 173kw (232hp, 235ps).

The US spec of the BRZ was 228hp. We don't know if that remains accurate (they are estimates) and we don't know what the GR86 will be in the US.

The most probable outcome is that the US version of the GR86 is exactly the same as the BRZ, just as they are in Japan.

I would assume both the GR86 and BRZ would have the same power output. Will probably be differentiated with tuning setup.

Do you think market specific equipment relating to emissions might why the GR86 is slightly higher?

The GR86 and BRZ are probably slightly higher in japan due to the premium fuel quality. Its 100 RON in Japan.

I could be wrong, it might be emissions related - I mean the BRZ spec sheet in the US says the car is 13.5:1 compression and this one says 12.5:1 compression, that's not something I expected to see.

If I had one wish it was that Toyota and Subaru made there cars flex-fuel though, it annoys me that I'll need to get the car chipped to have that.

I hope so, I don't want to lose on power, even if it's only a couple more.

And assuming the 86 has 4 more horsepower than the BRZ do you honestly think that's going to make a difference that anyone would notice? In 2017 Subaru and Toyota upped the FA20 engine from 200 to 205 HP in the manual version. But what made the car feel fractionally more lively was the final drive ratio change. And as I said it was only very slightly better. It did not get rid of the torque dip. The engine still sounded a bit rough. You still had to rev the hell out of it to get power. So 232HP if this happens to be on the US version of the 86 will do absolutely nothing on its own. Had Toyota upped the horsepower to 245 on the 86 we would certainly feel a difference. Yet you would still have to change the gearing to take advantage of the extra HP.

the extra 4 hp, if that's even accurate for the US market won't make any real difference. Except bragging rights,

@Blighty where did you see the 12.5:1 vs 13.5:1 compression ratio stats?

Good point.
It won't matter much in the end anyways when comparing stock vs. stock. The only differences we should feel when driving are more in the suspension setup and other chassis related things.

I will bet they are 100% identical. Any handling differences would be down to shocks, springs, bushings, and sway bars. I think they wear the same tires.
