So I am just at about the six month mark and had some questions that I probably should know the answer to but don't

First I know that in sport plus the engine takes longer to warm up, but is that also true of sport?

Second, is it just me does the car feel more true/direct/connected in MDM mode? I feel like going around corners in MDM mode is more fun, but is there an actual technical reason for this?

Third, does the car feel more naturally aspirated in sport as compared to sport plus? I initially used to always put the car in sport plus but then I switched to sport to avoid some of the annoying (to me) exhaust sounds of sport plus and I swear the car feels more boosty,laggy to me in sports plus, it feels more like a turbo car than in sport, or is that just me?

Fourth, is there a difference in sound (other than louder over run pops and bangs) in sports plus vs sport? I can't seem to detect any real difference other than the pops and bangs being more pronounced.

and finally with winter looming, what is the best drive mode for the white stuff, mdm or full traction control?

I look forward to hearing from the knowledgeable group on here that sometimes admittedly make me feel like a non car person

Car takes longer I believe because in S+ the the cooling fans kick on

Some traction nannies are turned off in MDM, and yes it defineately feels more realistic to me at least. I am always in MDM

I dont feel its laggy in S+, maybe a bit to responsive. I find S to be the every day happy medium. I use S+ only when driving in the twisties, where I need very quick throttle responses.

Sound: Perhaps slight difference but not much. I feel like the sound is correlated more to the outside and engine temps versus the two modes.

For the winter, I plan to be in the same drive modes...S and MDM. Just putting on winter shoes

so the cooling fans don't kick in in sport?

They do, but not right away. Put your car in S+ and you'll notice the fans kick on right away even if the car is cold, and stay on. It is a very noticeable sound when your windows are down.

They do but not until later. In Sport +, you can practically hear them engage as soon as you flip the switch. Thats because the car assumes you are about to do some heavy driving.

This. The oil temp will drop a bit in sport + if it’s all warmed up I believe.

Full stability on is pretty boring, the car stays very planted in my experience. MDM for any sort of driving near the limits. If you’re really going for it in an arguably stupid way, MDM will even get in your way a bit.

With respect to Econo vs Sport vs Sport+, it's really easy to see the operating temperature difference if you're cruising on the highway. Set the cluster to display oil temp, drive in Sport+ for a while, the oil temp stays at a solid ~190F, if you switch to Econo mode, oil temp will increase to ~215F. Drop back to Sport+ and temp drops back to 190.

The cooling strategy is just different for oil and coolant temp between the 2 modes, and the fan is one piece of the puzzle.

I can't recall Sport temp behavior nearly as much. Rarely use it (I'm in Sport+ ~90%, and 10% in Comfort). i do seem to recall Sport acting more like Comfort mode though in terms of temperature.

Could the exhaust flaps closed in economy mode cause more restriction, higher temps, and faster warm up?

Also,
yes full DSC on seems to restrict corner entry and corner exit a bit. Hard to describe but the car feels more willing to be pushed hard in MDM mode. And that's without trying to kick the tail out.

darn it, I was hoping there was no reason not to go right into sport as i find efficiency mode completely kills the life of the car in sound and responsiveness

I do have to agree with you on this but I can definitely say I like being able to get on the autobahn throw it in efficiency mode while cruising and be able to hold a conversation or listen to music.

I drive it in Efficient when driving it first thing, but only for a couple of miles. Weather is warm and there's no need to baby it after that. Now, in the dead of winter I'll probably give it a couple of more miles.

absolutely it has its place for highway cruising, but that's kinda where I'd like to limit it to...those first five minutes of city driving in efficiency are torture

At least on my commute, both efficiency mode and sport take the same time to warm up. Sport+ takes longer. In both efficiency and sport, when in fully warmed up the oil temp is one or two small clicks past the first large bar; in sport +, the oil temp stays on the first large bar.

Yes, MDM is the best mode when having some fun. I programed my M2 button to be in MDM.

I have not noticed this...

I think you're probably correct...

Sorry, I live in Arizona...

Efficient mode has one purpose: To get the oil temp up faster, so you can put it in Sport+

This is good news, you have saved me from the dullness of efficiency driving in the city!

but according to Kevinm, in fact there is no difference between sport and efficient in terms of warm up time.

I should test this myself but driving 10-15 minutes in the city in efficient is a hard pill to swallow!

While that's probably true from a cooling system standpoint, however, Efficient mode tends to keep the revs lower (well, you can shift manually at any revs) and better for the engine while its cold, so the preferred mode at cold start

[veenut28]

In my completely unscientific testing, the difference in engine warm up time is negligible between Efficient and Sport plus. And definitely not enough to keep me in Efficient once I'm out of my neighborhood in the morning.

I've been spending more time in Sport too. I find it more satisfying than Sport+. The throttle response is more linear, so that I can feel an appreciable difference between 25% throttle and WOT. In Sport+, it's hard to floor it since even a little bit of throttle input sends it.

Haha! Sorry, I was being slightly facetious.

I just meant to say that I don't really use Efficient mode at all for most of my driving. I use it mainly as that initial period for warming up, that's all. And yes, it is very possible that Sport and Efficient times are similar, but I haven't checked myself.

95% of my driving is either Sport or Sport+ with MDM.

I agree here. I am doing more Sport driving as well. The throttle, especially from a standstill, can be jarring in Sport+.
