I have a F10 520d SE with sports auto, this gives me the options of normal, sport and sport + settings. I tend to use sport the most with only the chassis option ticked which gives me a better steering feel. Now yesterday I used sport+ for the first time. I checked in the idrive and you can't configure sport+ so what exactly does sport+ do? Does it turn the traction control / stability control off / down
I did a 100mile journey home last night down the M6 and half the journey in sport and the other half in sport+. In sport+ the car feels much more planted and stable, throttle is instant and is much much more fun to drive.......why?
Thanks
