Sport button

[Marlon]

Am I correct in thinking that the sport button in my 3.0si just alters the throttle response, or does it also alter the steering too?
I know it doesn't alter the suspension or the power delivery.

I'm Sure it Makes the Steering heavier/ tighter

I believe it is just throttle response it changes Marlon

Hi,
Just throttle response and turns down the amount of power assistance on the steering.

Throttle response and tightens the steering electronically. Makes it feel "stiffer"

Interesting about the power steering; if that's the case then it's best to have sport mode off in city driving and parking so that you have the full assistance of the power steering. I'm using mine as a daily drive now, so whereas before I would always put the sport button on I'm now questioning using it all the time.

As said, more sensitive throttle, and reduced power steering assistance.

On an auto it also adjusts the gearbox to hold a higher gear than normal, and I think (though not 100% sure) that it changes the gear ratios too.

On SMG it also makes the gear change quicker

It also gives an extra 150BHP and changes the setting in the E Diff.!!

In stop/start traffic I find Sport a pain as you have to be uber sensitive with your foot not to use too much throttle and it's much easier to drive more smoothly in normal. As soon as you're on the move I like Sport for the extra steering weight and easier downshift blips. It's also good at higher speeds like on the motorway where you only have to move your foot a fraction of what you would in normal to speed up. Lazy but useful.

As said above.

Adjusts throttle map (essentially just less travel from idle to WOT).
Makes steering stiffer (except M).
Adjusts shift points for the auto.

I prefer more travel on the pedal so never use it. Would actually prefer a linear map and I've yet to see if I prefer the steering on track mainly due to the throttle sensitivity.

Bing -
It can't change gear ratios as they are fixed tooth gears. What it does do is change the up and down shift points to more aggressive settings for performance not economy.
It's actually therefore more often in a lower not higher gear.
(sorry)

Thanks for all the responses fellas, I'm now fully enlightened

Not strictly true...you can electronically alter gear ratios, we use a device in drag racing, that bolts to the rear of the transmission, its alters the gearing for street driving at the push of a button. We can go from a 5:10 final drive to a 2:30 for the foad, company called gear vendors make the unit.

Sport button doesn't do that - though would be fun :lol:

So the sport button helps you lose weight as well. Must press it one day. :lol:

I think mine must be broken

That's all actually what I meant in my head, but got completely wrong - I should re-read my posts, or simply not bother :lol:

Bing,
there is a device that can do that, and im sure BMW have the means to be able to do it too in their Mtech whatever gear system

Totally true for the Z4 that we are discussing.

Agree though you can get all sorts of crazy stuff in specialist markets.
My Jeep transfer case can change to high or low independantly on front and rear axle. Means my rear wheels can be going faster than the front. Useful to turn around in mud... Try that on a road car
