M Sport Button

I wish we had an M engineer on this forum.

Why? To ask why the button doesn't do more? It changes the input required on the throttle for the throttle position at the engine end.

In normal mode you press the peddle down 20% you get 20% throttle, all the way up to 100% pressed gives you 100%.

With Sport button on you press the peddle 20% you get 30% throttle, 40% gives you 70%, 50% gives you 100%. - all numbers are for illustration etc, this isn't actual figures etc.

It does not change steering (we don't have elec steering on M), it doesn't change dampers (we have normal simple oil filled dampers), it doesn't change ESP (you can always get some slip with TC on), it doesn't change gear change speed (we have a stick) - it's only there because the marketing boys asked for it!

I have never seen anything (from an official source) that says otherwise.

Keep your knickers on. To ask why put a useless button in an otherwise pretty uncompromising car. Would have made sense to hold off the ESP further/ change engine mapping etc.

Like your thinking! One press and a nice frothy cup of fredo cappuccino pops out.

Yeah hold a constant throttle on and press it... might get a bit of acceleration as it magnifies the input from the throttle to be less proportional.

I never get that, and have to release the throttle slightly and reapply to get any effect.

However when I switch off the sport mode the engine revs drop instantly and the car slows slightly.

Same here... When pressing the sport button nothing happens. When I release the throttle and press it again I feel a small difference is throttle response (that's it).

It does not change steering (we don't have elec steering on M), it doesn't change dampers (we have normal simple oil filled dampers), it doesn't change ESP (you can always get some slip with TC on), it doesn't change gear change speed (we have a stick) - it's only there because the marketing boys asked for it!

IMO the button is useless... It would be nice if the button chanced the DSC in a more sporty mode.

its completely useless, your right the only thing this car needs is a relaxed DSC mode, instead of on or off.

Still when im at the track driving with this off is scary but huge fun.
