dude , you don't 'have' to mash the accelerator to the floor every time you drive it. ( although it is fun sometimes)
Its variable,
Take her out driving around on some back country roads. Let her get use to it. She will love it. Good solid feel to the steering wheel, something happening when you hit the accelerator. None of that 'cvt' junk.
My wife loves our Scat Pack. She drive it in automatic, and motors around.
Its all good. well I do have to calm her down when she is entering the on ramp on the interstate. I tell her its merge, match speeds, but she thinks its Daytona ! LOL
I don't know about 'dialing it back' although you can like 'slidd' says. She will be disappointed in it then.
Just take her out driving,

Have a good one !
