I'm not a fan of diesels, anyway, though some over here are. Power/weight like you suggest, it just isn't there. But a highish boost 1.5 gasoline engine, could make upwards of 300hp and be quite efficient, no?
Im not a fan of diesel either, but 90hp and low CO2 would equal zero engine taxes in Norway. A little inexpensive chip would give a 116D extreme bang for the buck in terms of power..

Really hate the idea of a "sport mode" that just increases throttle opening per foot position, basically only makes it harder to modulate!

Unless this "sport mode" is something else...
Cars like the new 1,3,5-series ("F"-code cars) have a button that normaly have these 4 modes:
-Eco Pro
-Comfort
-Sport
-Sport+

This little mode changing button can change the following aspects of the car:
-Engine mapping (engine response, and maybe even a little change in power)
-Throttle pedal response
-Steering response (I think it basically just changes the weight of the steering. But it depend on the options)
-Suspension
-Automatic gearbox

-If you have a car with normal suspension, not adaptive (sport) suspension. It will not change suspension. You can have normal m-sport suspension without any electronic stuff.
-Manual gearbox will not be affected by the electronic button
-Steering, if you go for the normal steering it will not be affected by electronics. Not sure if every country have that option though. There are two "options" you can get on the steering.
So, if the car is made as simple as possible. The little driving mode button will only change engine response and throttle pedal response.

You have a traction control button with two modes:
DTC, press and its into traction mode. Nice for snow and stuff i believe.
No DSC (if you hold the button for 5 sec). Problem is, this is basically comfort mode (with E-diff) and no stability control. Why on earth would they make it go into "comfort mode" when you turn for the DSC compelety off?

-Eco Pro
-Comfort
_____DTC (traction mode, -comfort setting)
-Sport
-Sport+ (same as sport, but with less traction control, you can get a LITTLE sideways
_____NO DSC (sideways fun and do whatever, but with comfort driving dymanics)


So, lets say you want to do some track driving.
Sport+ = Great for going fast, but not a proper track-mode since electronics can interfer if loosing grip. Useless for sideways fun and drifting.
DSC OFF= You can now go sideways and do whatever you want. But not good for the track with sluggish throttle response/engine mapping. AutoX would be useless if you were competing. You would loose acceleration out of every corner..

That is how it is with current cars as far as I know..Im not sure if this is a problem all over the world, nor if the M135I work that way. I know the M135I can adjust some mode stuff that you can not on the normal cars.. So its better, and maybe even it can be adjusted perfect..
Proper M-cars should work fine..

I know there is a ton of stuff that is possible to get reprogrammed with a computer, free software and some OBDII cable. But not sure if anyone have found out that stuff yet.. The cars are still quite new, and the more hardcore people will probably just buy M-cars. It is certainly something Im going to check if buying a new "f"-series BMW.

Those things are what can be problems with modern cars, and a thing that might get worse in the future.. Coding/programing may be something that gets normal in the tuning process for enthusiats.. who knows..
I know there are people in germany who are quite good at it.
There are even pure "coding/programming" forums for BMWs. So there is hope, and help, and some cool stuff that can be done...

Previous 1-series just need an LSD, turn of DSC and your good to go.. But its heavier and not as good as the new models in most aspects..
