Sports mode - Engine wear, fuel economy ?

[unreall_23]

I notice the engine running at higher rpms when sports button is on. Just wondering if this is more wear and tear on the engine? Also will I get worse fuel mileage?

As far as the engine is concerned sports mode is the same as a more sensitive throttle. Back off on the gas a bit and your wear, tear and mileage should be identical - then again, if you have the sport button pressed you probably aren't driving for maximum mileage.

all sport mode does is remap the throttle.

You did mention if your car is an automatic or not. I know on the E39 sports with an automatic and the sports package that the computer was set to hold each gear a little longer than a non-sport version. On my old E34(540,auto as well) when it was in Sport mode the shifts were delayed much longer than in economy mode as well.

So maybe there is more to sport mode than just the throttle re-map???

Some additional info from the BMW literature. Again, the transmission changes will only apply to automatics.

Dynamic Driving Control (Sport button)
activates the Sport driving mode for quicker
engine response on demand, reduced
power-steering assist, and an additional
Sport mode in models with optional
STEPTRONIC automatic transmission.


Dynamic Driving Control provides Normal and Sport settings for throttle, steering and
(if vehicle is so equipped) STEPTRONIC transmission.

The only way the sport button should have any effect on the RPM's is if you have an auto. In an automatic/SMG the sport button changes the shift program.

The sport button changes
*the throttle response (all Z4 models)
*the power steering assist (all but M)
*the shifting on non-manual transmissions.

The only effect it might have on the car long term is maybe worse mileage, but that's only if you have a heavy foot.

i was also wondering the same thing. ('07 sport/auto trans here)

and i also notice when i press the sport mode. the throttle response is not as delayed and much more quicker.

sport mode = fun!

sport mode = addicting!!

i TRY my best not to use it in city driving, but getting on the freeway?
Weeeeeeeeeeeee

Ok mine is a 6 speed step. I don't stomp on the gas or anything in sport mode, but just feels unhealthy with the rpms always around 3-3500 or so?

That's fine. This engine was designed to be operated at high revs. 3k is absolutely not an issue.

I find the sport throttle mapping too sensitive, and don't use it.

Same. I'm more likely to turn the traction control down.
