I really don't want to be that guy that doesn't even try to look for an answer in an already existing thread... But after a straight hour of searching, I think it's time to just start a quick thread.. I currently own a 335i m sport and was wondering if the suspension lowered a few mm when driving mode is switched to sport +, (I'm aware of the stiffening characteristics) I was just curious about the lowering of the vehicle for better CG/handling when this mode is engaged. Bear with me guys, it's my fist beemer and I love everything about it, just trying to get familiar with all the bells and whistles.

I don't believe the F30 has that feature. From my understanding, if you have Adaptive Suspension, the mode settings changes the dampening ("stiffness"), but does not lower. If I am not mistaken, I don't think any F30 has option for air suspension.

I think the Mercedes C class has air suspension (Airmatic?) which can adjust the ride height.

[Humdizzle]

the car doesn't lower at all. the dampers stiffen up if you got the adaptive suspension option.

Not making fun of you or disrespecting...…...just educating.....

Thanks for the clarification 👍

*notes taken* lol thanks

The Beemer - Bimmer terminology thing is pretty common when talking about BMW's & most people are unaware of the correct usage.

I only knew about because back in the day I had a Beezer (BSA) Lightning.

are you sure you have adaptive suspension? if you don't, then sport/sport+ don't do anything for your suspension. throttle mapping/boost targets change and the steering feel changes, and that's it.

Boost targets don't even change. There's no more power, just a more sensitive pedal.

A prior vehicle i had, a Grand Cherokee Overland had that feature. It would drop 2" in sport/highway mode... was pretty cool!

I mean, I'm pretty sure. Is there any way of finding out for sure without taking the car out for a ride? I feel like the suspension stiffens up when I swap to sports mode.

Actually, my apologies. I'm an imbecile. I have the m sport package.

You're correct. BMW F30 is dampening only.

It does also change stability control behavior. The car definitely allows more rotation in Sport+ over Sport. Fooling with the settings during a track stint makes this very clear.

how do you think they get the pedal to be more "sensitive"? your fuel maps and boost maps change.

check your vin and see if you have adaptive suspension. you can be m-sport and adaptive.

yes, that's true. sport+ relaxes some of the stability control, but that's fairly obvious.

Your throttle position sensor could change, which would make it seem faster due to increased throttle responsiveness, but that would have no effect on fuel and boost mapping.

+1 My JB4 allowed adjusting the throttle sensor on the 335is & my handheld programmer does the same on the COBRA.

In both cases I softened the throttle to give me more throttle control for feathering during launch.

Yep. Same as all the ebay piggybacks. It just makes your pedal more sensitive to create a feeling of more torque. so pushing 10% on the throttle pedal in comfort is really 1% throttle opening (creating that feeling of deadspace ), whereas it's the full 10% in sport mode. The goal is to provide a smooth, soft acceleration from a stop with optimal fuel efficiency. It's also what allows rev matching/rev hang since the actual throttle position is all controlled electronically. Throttle by wire ftw.

[uncleruckus]

Most "sport mode" in cars only change throttle sensitivity and does not alter boost settings.

Some cars (e.g. Porsche) do have a "overboost" function which actually alters the max boost for certain time (e.g. +2 psi for 10 seconds).

Yup. Focus ST is another example of a car with an overboost function.

For our cars, Sport adjusts only the throttle response output, not the actual PSI or fuel mapping.

[torkles]

guys. i'm not claiming there's an overboost function. the reason the car feels faster in sport mode with the gas pedal pushed less than in comfort is because the computer is asking for more boost/fuel at that throttle position than it does in comfort mode. this is how cars work.

do yourself a test - on a private highway somewhere, in comfort mode, push the throttle in so that you are slightly accelerating. then, without moving your foot or downshifting, push the button in to sport mode. you'll feel the car start accelerating faster. and if you log it, you'll see there's more boost. throttle position has to translate to actual engine parameter changes in order for there to be 'more throttle response'.
