Button under gas pedal

I have it on my manual too. Gives it an extra kick if you go all the way on the accelerator and compress it

All it does is turn off the aircon/ancillaries momentarily to give you maximum engine power. The difference is barely perceptible really.

BMW, Audi and Mercedes all have these. There's the foot to the floor then there's more weirdly, if you fully depress the pedal you'll notice a little bit more this gives a full open body throttle.

Is this not simply the speed limiter override?

Pretty much.

It just lets the car know you want full power and allows it to override the other systems until you let it go.

The biggest different you can feel is when you set engine to ECO mode and then use this kick-down.
It overrides ECO mode and provides you as much power as possible.

With ECO mode full throttle without kick-down is still some kind of "slow full throttle".
