Why have a sport button?

I think the Sport button is useless. Why did BMW have to incorporate that button? Why couldn't they just have the car respond more crisper without having to press the button?

Now I can't stand driving the car without the sport button depressed. It feels slow. I know it doesn't add power, but response is much more direct and quicker.

To convince the KoolAid drinkers that they are getting something by pushing the button.

The only purpose I see fit is that it makes heal/toe slightly more responsive on the street. I don't even use it on the track

I find it works well on the track, but makes the car undrivable on the street since the throttle response is so sharp any serious bumps cause the 'bucking bronco' to rear it's head.

Why does the M3 do the "bucking bronco" thing at times?

So basically it's more on driver error than anything else. I've never had this "bucking bronco" syndrome before. Only when I launch hard and mistime the clutch release I'll stall the car completely.

But then again, I've been driving nothing but stick for the last 20 years. So maybe experience is on my side. Or maybe some of us just can't handle an "M". lol

I've only noticed this when my seat is not properly adjusted throwing off my body mechanics and preventing my foot from being secure, planted and stable on the throttle. That's why as much as possible I never let anyone drive my car. I hate having to adjust the seat again.

But other than that, I love how crisp the car reacts to your every input on sport mode.

I hate that...sometimes even in 2nd. Non-sport mode will do it as well some of the time. I have learned to just shift up when that happens or release the gas completely.

I've never noticed this "bucking bronco" thing you guys are talking about. The more I read into it, the more I get confused. Was this ever a problem when our cars were brand-new??? I really do think this is inexperienced driver error or there is some maintenance issue with your cars that needs to be addressed. lol

I don't get the bucking bronco, although I did get it a few times when I first got it when coming to a complete stop and then starting off, since your in first it's a lot more sensitive, but I only turn it on when I'm about to get on the highway or if I'm aggressively driving.. But for the most part I keep it off for doing my usual drive for here or there.

But going from driving with the sport button on, and then turning off makes the car feel absolutely dead for a minute till you get used it to it lol

Typically this is a manual trans issue, not SMG. The bucking bronco with experienced drivers will come from undulations in the road starting off in first gear. It is a wave effect. Inexperienced drivers it is caused from lack of muscle control with the pedal.

Sport button is useless especially when you change to lower mount fixed back seats where your foot angle is changed. Only useful for heel toe as mentioned above.

I am a pretty experienced driver, the bucking happens because of sport mode mostly and DBW over compensating.

I like the feel of sport mode.

I've always thought of the Sport Button as the pour-twice-as-much-fuel button.
