No, they programmed it that way to be quicker. If it feels "even more sporty", great. But the intention is to get from here to there (or around a circuit) in less time. The extra second or two that you save in a 11 to 15 corner circuit is significant to some folks.

OK, tested last night. At full throttle, both PDK Auto and Manual modes tested. Plus, I upped the tire pressure to almost high performance instead of comfort setting I was at.

It was better, but still not how I'd like it. The shift seems a tiny tad quicker now than yesterday, but I can't call it crisp like it is in Sport. And there still is a lot of squatting and twisting in the rear, almost like the diff doesn't know what to do with the torque. No such hassles in Sport mode.

That being said, roads are not completely level where I drive, plus temperatures are down (not freezing yet but below 7°C) to were I should drive on winter tires but I'm still on Pzeros.

I think I'm going to wait until spring comes along, leave SportPlus alone for the time being, when temps go up test again, and if I'm not happy I'm going to the dealer to have it checked !

As it is now, I don't like how SportPlus shifts. It doesn't feel safe, and it can't be good on the hardware. Bring on the M4 for a testdrive damnit, grrrrrrrrr ! And this BMW statement/thought is maybe a smoke screen for my mind not to tell me, "you should have gotten a manual"

And Jeezus, who on earth decided on the kickdown button. It just does a kickdown, even when I'm in Manual mode. DO NOT do that, stupid car, I don't want to die ! So bloody annoying !

That being said, there is a clear pressure point where you have to push through to get to the kickdown button. I wonder if, technically, this last position is 99% throttle and the kickdown button 100% throttle ... OR ... if that last pre-kickdown position is 100% throttle and the kickdown is 100%+kickdown .. very minute difference, but a difference nevertheless !

In manual mode, sport + shifts very, very smoothly when I use it (yesterday for example). Sport + in auto mode is another matter altogether but only when downshifting. But I can see where running in traffic that varies and is constantly just over or just under the shift point will be pretty jarring with the back and forth at the top of the range. Finally, when the temperature gets cold these stock tires loose a lot of grip and make the ride harsher and less controllable; definitely not the time when I press the performance of the vehicle.

Hmmm, I think I would take a tech for a drive and see if everything checks out. The way you are describing things it's hard to tell if everything is as it should be.

I have described the Sport Plus shifting as,.... Someone inside with a sledge hammer. Mine BANGS out the shifts like it's ***** to the Wall racing. I always considered it normal, even at Watkins Glen the race 911's bang the gear changes. I do not use Sport Plus around town. I think it is suppose to be designed for the Track. Not casual around town driving. That is how/what it is designed for...IMO...
