RPM In N Question, Please

[Bob]

Hello,

Have a 2009 Buick LaCrosse.

I have probably not looked at this recently, but when I put the
gearshift into either N or P, and depress the gas pedal to the floor,
the indicated RPM never goes above 3,500.

Is this normal ? If not, what might it indicate ?

I "seem to" remember that it would go to about 6,000 when I did this
previously, but I may be wrong about that.

Car seems to drive normally.

Thanks for help, as always,
Bob

Situation Normal. ECU limits no load rpm to 3500-4000 on most cars.
I forgot why.

Sounds like normal torque management. I saw something similar on
my '96 Mercury Sable.
