When in the Sport mode, my AT downshifts aggressively when I'm braking hard. And the harder I brake, the more aggressive the downshifting gets. The result is that the engine RPM's are kept high, as if in anticipation of the driver braking hard for a turn, then stomping on the throttle coming out of the turn. The engine is kept in the power band.

So yes, in this example, the engine is adding some braking, along with the brakes themselves. To me, it all seems to fit together quite seamlessly and makes spirited driving enjoyable. The car seems to know what I want, then delivers. Quickly.

What about long descends?

Would it still be wise to downshift for a 45 min downhill? I'm thinking of a road trip and remember there are some mountainous regions going from BC to CA.

You have eight gears to choose from. Just select one that stops the car from running away without constant use of hard braking but which doesn't over-stress the engine. Personally, I wouldn't want to exceed 4000 RPM for very long. With an 8AT there has to be a "sweet spot" where you can keep both the car and the engine from over-speeding without over-taxing either the revs or the brakes.

No need to drive like it's 1698. Leave it in D and let the car do the work. Or throw it in S and drive it! Or M and do a little gear rowing

So S gear would be the same as m gear....s1 lowest, etc?

The amount of misinformation in this thread is mind boggling.

No, S mode is more a more aggressive shift mode where it tries to keep you in the higher rev ranges (where the powerband is) rather than D where it shifts to a higher gear to save gas.

Putting it in S makes no difference to shifting if you have the car always in Sport+ though, right? It would be nice to be wrong on that lol

Yeah, and now someone is probably going to go off a cliff somewhere after heating up their brakes from trying to keep speed going downhill for 45 minutes because he didn't want to "drive it like it's 1698 [???]". There's a reason why they check the temperature of your brakes in mountains.

Two completely different things. The Eco/Comfort/Sport/Sport+ settings affect drivetrain, suspension and steering functions. They do not influence gear settings.

The Eco/Comfort/Sport settings absolutely do affect gear settings. In fact, driving in sport+ will prevent the transmission from shifting into 8th gear automatically, and other shift points are also affected.

also sport+ will hang the current gear at a high rpm were the other modes would auto change into the next gear.

Sport will do the same, i.e. there is no difference in throttle response between Sport and Sport+.

Shift points seem about the same rpm with sport+ compared to sport+ and the shifter in S

Much as I'd like to be able to make my car even more fun to drive with a simple gearstick click, it isnt necessary to do this?

I know that to launch you need sport+, shifter in S and traction disabled.

Well, That's a great chart, but I wouldn't use it as gospel. Kudos for the owner doing such extensive testing though.
In my 2016 (as opposed to his 2014) I've found that with the DSC off and in DS sport shift mode the shift RPM, kick-downs, shift-speed, and exhaust burble are as aggressive or more so than in Sport+ mode. One of these days at a club meet we're going to do a side by side comparison. I know Anthony235 thinks I'm crazy, Ok he knows I am... but I can still have a somewhat valid point!!

dsc off does not have same throttle response or burble as loud as in sport or sport +. dsc off is comfort throttle mode.

I have no muffler with a catless DP, very easy to tell the difference in sound.

the m2 burbles louder when you when you hit the dsc button for some reason, not our cars.
