I'm on the same page here. In manual mode you can slightly bog a gear if you wish not to have light switch power coming out of a turn too.

ah maybe. I've been using Track with PTM Sport 1 or 2.

Hmmmmmmmmmmmmmm well only one way to find out...will need to schedule another track day!!!

I agree with Stephen and TheRealJA105. Going up a gear sometimes helps with smoother application of power. Also for tracks with a good bit of elevation change the A10 downshifts in some spots that really seems to upset the car and it seems to really overflow the car in certain places too. It does seem to get a good bit hotter when it shifts itself. I’m sure the car is quicker leaving it to shift itself but i don’t feel I can be as smooth and things don’t seem as predictable when it’s not in manual mode. It’s still a blast either way and if I were on a flatter track I probably would just let it do it’s thing.

I leave it in Drive using PTM Race, but I have found if you are late on throttle on corner exit, then it will sometimes downshift right when you get on throttle (HELLO!).



The key is to not drive like Ms. Daisy.



The ratios on the A10 are too close and you shift all the time if you do it yourself. You'll be faster letting it shift since it keeps you in the power band constantly. It also gives you limited engine braking (nothing like a manual).


Edit: The track config may play a part in the awkward shifting. The 2 - 2a -3 set of corners looks similar to where I've experienced issues. I just took up my corner entry speed 5 mph. Problem solved!

I will need to try it again and as I start to feel more comfortable with the track, my personal capabilities and the car I am sure everything will work out better. It probably had a lot to do with my braking or lack of which is why the car was having trouble figuring out what gear it should be in...as my technique increases I am assuming it can only get better transmission wise.

Plus because I was not in a PTM mode per say I am wondering also if that had anything to do with it?

Every dual-clutch driver I know at tracks here in CA, driving cars like GT3/RS, M4, GT-R, 488, McLaren 675 and 720s, AMG GT, etc. all use the paddles and believe they get faster laps shifting manually. These people are in the fastest 10% at our HPDE events, and nobody leaves it in auto mode. It seems like the experience with the A10 is different, is it because of the 10 speeds and gear ratios?

[Stephen12ZL1]

I believe most of the "all over the place" scenario is due to the track configuration and driver hesitation. If you are driving harder with more confidence, "D" may be a better choice. At VIR, the elevation and weird off camber areas may cause grief when using GM's shift algorithm in "D". Car and Driver used "D" for Lightning Lap but for a 20-25 min session in traffic...paddles would be likely preferable. If your track is generally clear then by all means send it in "D"!

That is a good point.. When I'm driving the track hard it stays in the gears much longer.

Well, I mean your second words said it....apples to oranges to nectarines.

On the track that I go to I let the auto do the shifting and I couldn't be happier. I came from a Gen 5 ZL1 manual and I can heel toe as well... The A10 is better than I am. However if there ever was a complaint it would be the downshift from 4-3. At times that shift really upsets the chassis.

I like how i said i'm on the same page and my post literally started a new page

I have the A8 so you might be correct about those extra ratios, but i still like to know exactly what gear i'm in. Fact it will keep the trans cooler, fact you can run lower rpms when you want, and fact if a shift upsets the car it's your fault. I tried auto a few times and it did seem to shift when I didn't want it to and it affected my driving style. Maybe i could get used to it and go faster though.

I finally got to the tracks this past weekend (Sebring) with one of the local Porsche clubs (Suncoast). The car had 1040 miles on it. Went out first session just Kind of cruising(PTM / Race) left the car in drive and turned a 2:29.3. As some mentioned a little inconsistent when shifting. Went out the next session and stayed in manual shift mode. I did have some trouble with shift points and bumped it off the limiter 3 or 4 times per lap and managed to run a couple of laps in the low 2:27’s. The last session I ran had a better feel for the car. I left in in drive a ran it pretty hard. Leaving it in Drive was the trick the shifted much faster and harder than I had thought it would, when braking hard the car down shifted perfectly and consistently. This is my first automatic and I could not be happier. I ran 5 of the 7 laps in the 2:25’s with a best of 2:25.0 . The Air temp was 96* and the car never missed a beat. With cooler weather and some stainless brake pads I confident the car will go sub 2:20 at Sebring which is pretty damn fast. The only thing done to the car this time out was change the brake fluid. This car is fun and fast.

I was at auto club speedway and in the laps where I was learning the track, driving 70%, it kept jumping between sport shift and regular. It annoyed me so I just switched it to manual mode. But when in aut it was shifting a lot due to it randomly dropping back to normal mode even under 70% throttle. Didn't try auto in later sessions so not sure if driving harder made a difference. I was in track mode ptm1 then 2. Switched to track later.
