I was watching The Topher review the 6MT Supra and his take away was that there is no reason to shift that car - in or out - of third gear when driving on backroads; the power is just always there, unlike more “fun” manual cars like the BRZ86, Cayman, Miata, etc. where you have to hunt for power.
There’s simply no reason to downshift, left alone upshift without reaching outlandish speeds. He argues this takes the entrainment factor out of the manual transmission, and that the 8ZF makes it more fun if you want to bang through gears. It sounds like the M2 will suffer the same problem.

What a bunch of BS. I had a C7 7 Speed Vette and I can still run through the gears in tight mountain road. You can be in 2-4 gears depending on how high you want to rev out your car. On a Brz, you will have to do more shifting that's for sure. On a higher powered car with longer gears, you can get away with less shifting or staying in one gear but you can still run through the gears. You have the options.

Probably best to envision the thrill you’ve had in the past when driving in the backroads.
Are you driving balls out or taking it pretty tame with somewhat increased entry and wot exits? Engagement from a 6MT makes it a drivers car for me. It can change one day, but the nostalgia and thrill is priceless. If I envision auto giving me thrill, it’s from the upshift sounds, not from the shorter gear ratios or quick shifts (as you can still feel delays with the ZF). So if I have to go wot and upshift, I’m probably going way too fast in this car to enjoy the nice backroads where I’m better off at a track. Real question: Coming from 6MT driving habits on fun cars, does it feel off to have rpm’s hang high while decelerating in auto? I naturally look for extra shifts up/down. |

I have about 1700 miles on my G87.
If you are pushing it on some fun twisties I have found I bounce around between 2, 3, & 4. If you’re stuck in 3rd I say you should find better roads. |

Most of the roads around me are extremely twisty. Very few opportunities to drive a 450 horsepower car wide open throttle or close to the limit. Nature of mountain driving.

While it’s true the gearbox is a wide ratio one, with longer gears than sporty small cars with lower power, you still need to shift more in this car.
To put in perspective, you’ll have to shift a BRZ or Miata way more often because of shorter gears, but the S58 requires way more gear changes than an N55, for example. I assume this to be the case for the B58 too, since those engines will have a lot of power in the low RPMs. In the S58 you have to hunt for power in the right range, above 4k RPM. So I don’t think the comparison with the Supra is apples to apples, to answer your question. That’s not to say a BRZ or Miata will require more shifts still. Look at the Thottle House review of the M2 in 4th gear at low speeds. You’d be shifting to second there. Sometimes that’s 2 gear shifts down. Which is pretty fun. I’ve never had a car that required first gear downshift, and the S58 does… it’s fun. The 1st gear is very short though. As to the comment of “you’d have more fun banging through gears with an automatic”, I guess to each their own, but to me, 1 single gear change in a manual is more fun than 20 in a flappy paddle… pushing buttons is not changing gears, in my view. And the old adage is true for the reviewer: if you are on the fence or compare manual vs auto, get the auto. |

The point is you can still run all the gears as you please. Just because you can stay in one gear doesn't mean you will. Part of the fun of driving a manual is gear shift. I can drive my C7 on the highway with just 5th but I still use 4th, 6th and 7th just for the fun of shifting when i feel like it. |

So yes, sure, there are totally going to be roads where you would drive in third gear all the way. If you are in twisty spots where you don't want to get sideways, such as the side of a mountain, it makes sense to stay in higher, less torquey gears. Edit: I would personally not limit drive on the side of a mountain, but I'm not here to judge lol. |

Its very manageable. You can stay in second and step out a little in a corner or stay in second past fifty and red line and chirp 3rd.

in theory, yes you can use 3rd gear for any sort of driving where you'll be 15-90mph or whatever the redline is at. but if you want the most performance you will be shifting.
the supra is different because it has a broader powerband and less weight than the S58 cars. It has an identical 5-60mph to the G82 manual. G82 is lighter and more power than the G87. i've never found a ZF8 that was fun to shift. so there's that part too. the downshifts are laggy. i'd rather have a dct or shift myself so i can at least feel something. I'd still go manual for the M2. Get a mild tune to wake up the low end, autosolutions ssk, and ucp to improve the shift feel.

I guess you could just leave it in 3rd, but it will be slower and less responsive than shifting. And at that rate, why not leave it in 4th or 5th? There is enough torque to accelerate in those gears. I'm pretty sure that there will be plenty of reasons to work the gearbox in the G87. -Nick |

I spent most of my break in miles in 3rd, 2nd, and 4th. The video I posted was primarily 3rd and 2nd.
Do with that info what you will.

C&D posted the ratios for the 6MT.

Damn, wish we had speed in gear for the old cars to compare. The ratios/final drive are the same, but the redlines are different and the rear tire circumference is probably different as well.
Edit: I did math. G87 Rear tire circumference: 83.9 inches F87 rear tire circumference: 82.6 inches |

Looks similar to the 135i N55. And you’re right, higher engine speed. But older E9X/E8X will hit 62+ in second gear, and will have gear to go to 300km/h (the 177mph above is just a limiter).
