I wasn't aware 6th gear was so short on the current model; it is certainly not ideal. We'll have to see if Subaru has reworked the 6th gear ratio to fix this. Addressing it by going to a taller final drive is not the solution. In addition to the loss of acceleration this would engender, it would reduce a driver's opportunities for shifting at high revs without violating speed limits (just ask Cayman owners).

What do You predict on 1/4? Around 14.2s?

If we use Car and Drivers 14.8 sec 1/4-mile for a baseline, probably more like ~14.5 seconds. Of course very driver, tire, and launch pad dependent...

Only 0.3 improvement? I'd guess almost 30hp, 50nm more and MPS4 would give better results than 0.3s....

In WGDR5 on MotorTrend 160hp MX5 did 14.5 at ~94mph, Car and Driver got 180hp MX5 to 14.5 at 95mph. BBR MX5 with 190hp does 1/4 in around 14.3 so I guessed it may be closer to that/slightly faster.

Not sure if they will change it from the updated 4.3

On 18 inch rubber at 4.3 final, its almost a wash with v-max on the 17inch 4.1 OG. You will just be getting there quicker

And, of course, there is no way to know at this point, just thinking out loud.

Good questions and here's another:


If you're parked with engine off and turn on accessory to listen to music, will you still hear the sound of the engine? Sort of like if a tree falls in the forest and no one hears it, did it still make a sound...

18" rubber is same diameter as 17"...

I've posted this before, but assuming same trans ratios, whether they go with 4.3 (kinda doubt it) or 4.1 (most likely?) or 3.9 (still more torque to wheels vs. current model), it's gonna have more thrust from any speed vs. '17-'20

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.

They could certainly reverse course if they want that 0-60 number to look better. But as you say... if they are thinking straight, this shouldn't be something they put their money on, and they certainly didn't on the 2017+ refresh.

The rest of the gearing is fine, but I've always wanted sixth gear to be taller. Sixth gear is a cruising gear. It never made sense to me that it turns the same RPM in 6th at 70 as my 30 year old Celica does in 5th.

I have never had a problem with the short 6th in my 2018. I love it. Feels great in every gear, and it is more of a true sports car after all. Not sure that there would be any real benefit in lengthening 6th gear. I get 35-38 mpg cruising at 3500 RPM. I don't see much of a difference at 2500-3000 RPM - and to obtain that much difference, 6th gear would need to be a good bit longer. In my opinion, it would be inconsistent and I would hate it. Currently, all the gears shift in perfect line one after another, feeling consistent at shift points, etc. A long 6th gear would have a much greater drop in RPM when shifting from 5th and would bog the car down heavily. Certainly an opinionated statement, but I could care less for a "cruising" gear in a sports car like this.

They may go back to 4.1 coz of emissions and fuel raitings.

For me stock 4.1 was way to long given the moderate power and torque dip, it felt like it didnt want to rev. Stock it feels way worse than base Cayman987, it has long gearing too but has some power and nm to back it up. I went to 4.67 MFactory and there are days I think I should have gone to 4.88, I actually rarely reach 180kph+ speeds (no need) and I dont do longer trips. So having even more torque and faster revving would probably be even more fun on daily. Having said that I'd like to have agressive 1-5 and longer, cruising 6th.
Supra (I know, 8gears at) is also geared agressively, it reaches same in-gear speeds (1-5) as my 86 which was suprising for me given its power and over 500nm of torque.

On GR86 I'd go with 4.67 at least, maybe even 4.88 for autocross setup and short, technical tracks. Shorter gearing wakes this car up for real and new one wont be an exeption.

The twins just aren’t intended for the 0-60 crowd, it will go for an Ecoboost Mustang or equivalent, so it’s hard to see Subaru or Toyota running the “better numbers” ploy, but who knows.

Please - please - please I hope they do not go to 3.9 just to improve 0-60 times.... And yes, I do understand that 3.9 might be an advantage for some people on some tracks. I am running 4.56 on my 2013, and I think 4.3 would be wonderful on the 2022.

That's fair and to each their own. But I've spent some time on and off the track and outside of (maybe) COTA or Spa, you never have a reason to be in 6th gear. I don't think I went above 4th on the 'Ring. Meanwhile, this car is a great "Baby-GT" and I've done plenty of road trips where it would be nice to turn a few less Rs over the long haul. With the added torques, there should still be plenty of oompf for casual passing, and if you need more, the downshift if right there. I also don't think you'd see any significant bogging between 5 and 6. You can comfortably shift to 6 at 40mph right now; so maybe you wait until 45 instead?

It all depends on whether they tweaked the gear ratios or not.
