2017 FT-86 More power for manual but not for automatic transmission

[nikitopo]

Final drive or gearing ratios don't change the engine's crank horse power. The only reason I can imagine for the 5hp difference were issues in the emissions. They had to program the engine in the auto to be more conservative.

You lazy uninspired, ah fuck it....

Well from Subaru's website it seems pretty clear that only the manuals get the power bump, and that it's a result from a retune. This is directly from their site.

Direct-Injection SUBARU BOXER® Engine
The direct-and-port-injected 2.0-liter SUBARU BOXER® engine has been retuned to provide up to 205-hp. Coupled to a close-ratio 6-speed manual transmission with revised ratios, BRZ offers enhanced mid-range responsiveness to your back road adventures.

So maybe it sounds like the torque dip is being addressed? Or did I not read that right?

It sure sounds like it

I don't know this actually takes me back to my original theory that both get the HP but the MT also gets a tweak. The Toyota one said something similar (to lazy to go find it) but it was all in one sentence. This is clearly two separate statements.

"The direct-and-port-injected 2.0-liter SUBARU BOXER® engine has been retuned to provide up to 205-hp. " "Coupled to a close-ratio 6-speed manual transmission with revised ratios, BRZ offers enhanced mid-range responsiveness to your back road adventures."

I could be placing to much importance on their grammar and punctuation but I keep wavering on whether it is one or both. Had total gone over to the MT only camp until this quote appeared and now I am wondering again. Eventually it will be 100% confirmed one way or the other and I can sleep again.

I get that but why would they say up to 205? Instead of 205?

Ah shitt!!!!
I am back on the other side of the fence.
Went to the Subaru press release to check wording and it is VERY clear. I can finally end my flip flopping.

"The BRZ 2.0-liter SUBARU BOXER engine receives several internal updates for friction reduction including new valves, camshaft and cylinder heads. Accompanied with a new aluminum intake manifold and redesigned exhaust manifold for increased air flow, the engine output in models with the 6-speed manual transmission is increased to 205-hp and 156 lb-ft of torque. Also, a lower final drive ratio from 4.1 to 4.3:1, paired with the standard Torsen® limited-slip differential, improves acceleration on models with manual transmission. "

It makes no sense to manufacture two different, nearly identical, engines at the same time. They might only be talking about the manual transmission because they updated the manual transmission.

That was my thought as well but it is very clear in the release (no idea how I didn't see that release before) so I guess that is what they have done.

Which is confusing to me. Toyota is not known for doing things inefficiently. Subaru used to make randomly different cars in small numbers, but they haven't done that in a long time.

Awe definitely helps clarify that! Not sure how I missed that part as well.

In before someone bitches about it not being turbo for the upteenth time.

It makes it seem as if the tune is the reason for the power increase in the manual. That would make much more sense than a different engine.
