Does it ever stop??....plus de flap? - Page 4

the question seems to come up quite frequently, and the responses are often varied and erroneous.
1. does the sport button change the engine map?

No, it only changes the responsiveness of the electronic throttles, so that less input with your foot on the accelerator pedal yields more output from the throttles than when in normal mode.

2. does it add power when the sport button is pressed?

No, although the car seems to feel invigorated, again you are only getting more fuel into the engine with less effort from your foot.

3. my petrol mileage seems lower when i drive in sport mode?

Yes, yes it does.
actual mileage may vary, it is likely that you will consume fuel at a faster rate with sport mode on.

I fully agree with it regarding the feeling and behaviour of the car with Sport Button. I noticed also the raising of consumption.
One important thing for me : it is less safe to drive with Sport Button "ON" in the moutains. The car is less easy to control...almost dangerous on very small moutain road.
Then, for me, the removal of the flap is a perfect adding of a driving without Sport Button "ON".

To me sport on gives the most accurate representation of a cable operated throttle pedal. Not too many years ago I had a Lotus Elise running throttle bodies that were functioned with a good old fashioned throttle cable. Sport on mirrors this the best. With sport off I find there is an unnatural dead spot in the first 1/3 of the travel. I guess this helps prevent any jerky throttle inputs and makes motorway cruises easier.

As an aside I do feel the SMG is sharper with sport on. Perhaps it's just in my head.

It certainly feels that way with DSC off and 'S6' selected

My experience also.

Sport on permanently, sod the MPG.

Agree. Having owned and used extensively two M cars with throttle cable can say sport mimics them perfectly. I even put sport on to move the car 15 foot back into the garage. Just bought an E46 320d sport touring as a daily smoker (it's Silver Grey as well

) it's throttle is probably more responsive than sport off

While sport mode doesn't add power or change timing, it is a bit more complicated than that. In addition to having a more aggressive throttle map, sport mode also allows the engine's torque to ramp up more rapidly.

Forgive my ignorance but wouldn't mean torque earlier in the range more power aswell?

When I say it lets the torque ramp up quicker, I mean in term of time, not the rev range. So while you might technically make more power for a fraction of a second, the end result will be the same. What is different is the responsiveness.

Wow i am impressed, i thought its just some gimmicky feature that makes the throttle way too twitchy.
I shall use it way more from now on. Thank you for clearing that up.

Do you know if the normal m3 shares the same behaviour?
Apart from the function of the flap, of course?
