GR86 GR86 - The “Auto Zone”

[James-UK]

So despite telling TUK Online I didn’t want my car until 01.03.2023 and being assured that was fine it’s now in Hull Where it will be staying until 01.03.2023 , at least I should have a definite date to collect it

The new plate really mean that much to you?

Yes , plus holidays , building work, car to sell and y weather it’s only going to sit in the garage

Looking forward to the reports and if the box blips on down shifts with more revs on the engine.

It will do. The previous gen did. You need it in 'manual' mode of course to do this.

I thought it would I’m expecting to use 2/3 quite a bit on some nice twist local B roads

I have just found the Auto Zone

Just 350 miles or so for me at the moment, so pottering around. It all feels very smooth, but have booked the Javelin Cadwell winter sprint on Feb 12th and Brands Hatch on 23rd, so will be able to see what it is like on track.

Did you see the comfort/normal/sport modes for the ACC? Have only tried normal so far and it accelerates faster than I would normally, sport sounds a bit aggressive

 

[Ersakus]

Currently running in so I did not try sport or manual mode too much. They make me go above 4K rpm easily

The AT rev matches in all modes. Only once it denied low gear. Not sure but it was 1st or second on an A road. That low of a gear would have hit high revs I think and the computer said no

Exactly why AFAIK there are no wrecked engines in the US cars fitted with the 6AT , “Money shift please - Computer says NO”

The old AT transmission let you over-rev though, so don't know if that's still a feature.

So lets say I was in third and hit the RPM limmiter, it wouldn't auto change up when I was in manual mode. It would let me continue to over-rev to max rpm. Is that still a thing?

Fyi - you auto boys gonna hate me, but to me the manual is so much better NO RAGRETS

 

[Ersakus]

There is a video of a manual gt86 on nuerberg ring I think, basically this young lad puts the car in 1st or second by mistake and the car span, the front of the car was destroyed and he was happy to be alive. For track use one needs to be careful with gear changes.
I think the auto saves us from doing lethal changes. Also auto rev match prevents slips and spins. I have no problem with that at all!

I am still to try after run in period

 

[cc3]

Happy with the auto seems a decent box. Throttle response instant. Good fun and a great package.

If you are on the rev limiter then you are not over revving the engine you are simply at the max safe working limit with the margin of safety that the engineers designed in

Having driven the manual I’ve absolutely no ragrets/regrets or otherwise with my choice

 

[Swizzle]

I've started to raise my rev limit as the 1000 mile mark get closer, just need to get out of london traffic!

Yeah I don't mean over-revving. But the cool thing about the GT86 auto was it didn't automatically force the upshift... a lot of cars do. So I'm hoping for your sake that the GR box is the same, im sure it is.

Let me know

 

[Ersakus]

Yes I think it is the same as before so far.
It holds the gear and you can rev it up.

But that's not over revving is it? That's just hitting the limiter, the same as you would do in a manual car. There's no harm done because you have a rev limiter. I did it a couple of times when I reviewed the manual. But it won't let you down shift if it thinks the revs will be too high. It can be a little tight with that. I've only driven an auto GT86 (with turbo) once and that was on track. The gearing is a little long on the auto I found.

Edit: just read your reply. Doh.

 

[Ersakus]

The gt86 auto would hit the rev limit and fuel would be cut to reduce the revs in manual mode (to protect the engine I assume). It is an unpleasant experience when fuel gets cut. A rude message to the driver to shift up! In D or sports mode it would bounce off the rev limiter and shift up immediately.

Once I’m out of run in period I will test the gr. I assume it will do the same.

 

[Swizzle]

Im run in, faux rev limiter off, sport mode, manual, 2nd gear downhill slip road and, the traction kicked in at 6k
I decided maybe today wasn't the best time to try it as its barely been above freezing and poodled home, the back end kicked out leaving the exit slip road
Tried up and down the box on the way, pretty sure it does blip as there was no real kick of engine braking,
Sport mode definitely gives more piped in sound but i think hitting mute on the stereo turns it off
Roll on spring

 

[PaulT]

What we might find is that the downshifts are quite conservative, ie. rev up to maybe 4-5000 rather than 7000. This means you don't get so much engine braking, but on the plus side it is less likely to lock the rear wheels.
