Sport button on 2012 Roadster S

Should there be a noticeable difference in performance when during acceleration the sport button is activated?
The green light comes on but I'm wondering if the circuit has a fuse?
I assume a message triggers a response from the ECU but I can't trace the circuit from the Haynes manual.

Just quicker throttle response

I believe the only difference (apart from unnecessarily heavier steering) is throttle response.

Certainly I can't feel any more power in mine.

the sport button does not make extra power nor does it change the suspension settings

it stiffens the steering by reducing power assist, changes the throttle pedal to throttle body relationship to give more throttle plate movement from less throttle pedal movement, turns on the pop and burble (not on all models/years) and if you have an automatic, changes the shift patterns both for up and downshifts

Pressing the SPORT button, its a manual shift, does cause a noticeable small jolt as if its going into kick down, only small but noticeable so it obviously does do something to boost the performance.
Then once engaged it does feel sportier and acceleration is definitely better at the lower revs.
So whether you are supposed to feel anything I dont know, but I can in mine.

I believe the small jolt is a result of the more immediate throttle response and is not an indication of more power.

Yes, in a manual car all that happens is that for 50% accelerator pedal movement, you get 75% (or whatever - more than 50%) throttle opening with the sport button pressed.

So it makes the car seem 'sportier' if you drive gently. If you use full throttle by (shock, horror) pressing the accelerator pedal all the way down, the sport button doesn't do anything. But lots of drivers never, ever use either full throttle or full revs, so they are impressed by how 'sporty' the button makes the car feel. It ought to be called the 'little old lady' button.....

I seem to remember seeing a Top Gear some time ago where The Stig did a lap in a car with the sports button activated and another lap with it de-activated - the lap time was almost exactly the same!!

It all comes down to how far you press the pedal on the right!!
