I'm sure the reason for shaping the engine's sound digitally rather than through mechanical design is all about the bottom line, the costs for the design, materials, and production of even a sound tube these days would far exceed those for a software sound app. Personally if it's a choice between the unappealing sonic character of the current engine and a more pleasing if artificially augmented sound I will live with the latter.

Don't worry guys! There are ways to raise the rev limit so you, yes you can find out why Subaru didn't!

I like the sound of the car, but I have headers, catback and lots of boost. I have heard a lot worse from 2L engines.

I noticed you have a 2017. I didn't like the stock sound of my 2013 much (even with a Perrin catback), but I actually enjoy it now with the 2017 OEM header and intake sound tube delete. From 4000-7400, it sounds really good IMO.

I agree with his comments about not getting a turbo. However, his engine torque / weight comparison raised an eyebrow:
Quote:
Also, he based his comparison a on crude preliminary marketing plot. Not criticizing him for that (we've all bench raced), but it's worth noting that what we get in the real-world could be quite different. Lastly, complaints about the torque dip are overblown, in my opinion (though obviously it's nice to see them smooth it out a bit). Of course, I'm one of the few who liked the drift-happy Primacy HPs, so what do I know?

If Toyota and Subaru are thinking straight, the gearing on the new model will remain as-is, rather than using a taller final drive ratio. By keeping the current ratio the performance gain from the new engine will not get diluted - which is important, given all the complaints about low power and slow acceleration piled on the current model. Choosing to use a longer ratio would be a very poor marketing decision.
The mid-cycle refresh brought a shorter final drive ratio to improve performance, and there's no feasible reason for Toyota and Subaru to reverse course now. Any improvement in fuel economy a taller ratio might offer would be marginal (and arguably not of importance to this buyer segment). And given the minuscule contribution of BRZ/86 sales to the companies' overall vehicle production that improvement would make no real difference to their fleet mileage numbers anyways.

The electronic exhaust sounds would almost certainly have some interconnection or perhaps even be built into the head unit. So:
1. Will replacing the factory head unit neuter the electronic exhaust? 2. Will the electronic exhaust create any problems when replacing the head unit? And, of course, there is no way to know at this point, just thinking out loud. |

Still, until the car is released and tested, we won't know how much faster it'll be (a few tenths in the quarter mile wouldn't surprise me).

"The 2.4-liter naturally aspirated engine redlines at 7,000 RPM and delivers a 15-percent increase in torque." Also, 184/156 = 18% increase in peak torque, but as displacement increase suggests it's up by 20% throughout most of the rev range, and less bumpy. Quote:

I understood why it was there (my gas mileage now demonstrates its loss), but it was still rough. Quote:

A taller 6th gear would be welcome. I agree that they should not touch 1~5, but with the added low-end torque, running at 2700 or so @ 60mph in 6th is overkill. Not sure what if any milage gains they would see if it was in the 2~2400 range. Regardless, the larger engine will make short-shifting around town less of a pain for those who want to maximize fuel economy.
