Automatic Mode question after downshift
Happy Saturday everyone!
Last night I had a dream that I was cruising down the highway in my non- z51 in “my mode” when a mustang GT approached me and asked to do a drag race from 60 MPH. In this dream I agreed and although I was in drive mode I held the left paddle so it could downshift to 3rd gear. When we started moving i didn’t realize I had to shift myself from 3 -> 4 even though I was still in drive and not manual because I thought it would naturally upshift at redline.
The next time I have a dream about racing someone on the highway would there be anything I can do to ensure I can manually downshift in drive mode but the car will still shift itself once I floor it? Thanks!

- When in auto mode and you over ride it the DCT will stay in manual mode which means you bumped off the rev limiter when your car did not up shift automatically. If you paddle down for a hard pull you must be ready for an almost instantaneous upshift. The car will revert to auto in about 10 seconds long after you hit the rev limiter!

have never really used Z mode because I felt the other modes have what I need covered. Can I set Z mode to be able to automatically shift for me in the scenario I posted on?

Z mode is fully customizable. set engine, trans, braking, etc to "track"...suspension to "tour" or "sport" for street use

"The C8 has two manual modes. If you pull a paddle while in Drive, you get a temporary manual mode, which automatically times out, or can be exited sooner by holding the upshift paddle. In this mode, the car will automatically upshift at redline. If you press the M button in the center console, you get full manual mode. There's no time out, and the car won't upshift at redline."

It's not clear why a manual down shift (in any mode) while in Auto mode would hit the rev limiter ..... But it does unfortunately. This would be a great improvement to have a setting for this!! Porsches will shift and not hit the rev limiter, not programable.

The driver modes won't effect whether or not the DCT upshifts at redline. Using the M button on the console puts the DCT in permanent manual mode and it will bounce off the rev limiter. However using the paddles puts it in temporary manual mode. In temporary manual mode it is supposed to automatically upshift at redline.

Tons of mis-information here ! In the ops dream he was driving along in auto when the Mustang pulled up and obviously wanted to race.
The op correctly wanted to be a gear or 2 lower BEFORE the start just as you would with a stick. Being in track or Z mode would have caused the car to downshift AFTER the start while the Mustang was already in max acceleration. In the given scenario unless the Mustang wants to give you a few seconds to "setup " only thing you can do is pump the down paddle a couple of times till you are at optimum powerband and then mash the pedal being ready for an instant manual paddle upshift before red line. Having the car down shift a couple gears in Z mode or not After the start, although only taking a few tenths of a second will not be conducive to a win.

BANG BANG 1 OR 2 DOWNSHIFTS WITH PADDLE THEN MASH THE ACCELERATOR and almost instantly do a paddle upshift before hitting rev limiter
If that doesn't work nothing else will !

Absolutely false..On the street I leave my car in auto almost all the time and override with paddles all the time. Unless I stupidly try to downshift to "over redline" or up shift to a "severe lugging situation" the computer does not even think of overriding my commands. An average passenger would not even know when I am shifting versus the computer. I have done this thousands of times over 2 years so please do not try to tell me I'm wrong!

I would..
hit Z mode, and punch the gas.
It will pick the proper gear faster than you can pull that downshift when you hit the go peddle. ...
Track mode will change the suspension setting to too hard for the street. .. Z mode can set the engine/shift to track mode. ...

You don't hit the downshift paddle after you hit the gas you do it before. when you hit the gas the car is already in the correct gear and nothing is faster then that. In the ops scenario the race starts when he hits the gas, in my scenario the car is setup before the go signal so is faster since the car needs to do nothing, down shifts have already happened!

To exit Temporary Manual Paddle Shift mode
do one of the following:
• Hold the + paddle for more than one second.
• Drive at a steady speed without
manual shifts or aggressive cornering for
several seconds.
• Lower vehicle speed to 6 km/h (4 mph)
or less.

But if you just mash the pedal to the floor in auto mode, the car will still downshift without you having to hit the paddle. It might lag a bit compared to using the paddle, though.
