Well....I tried!
Not that wheel spin is something I want...but I thought I'd give it a try.
DTC on...power breaking...nothing.
I think the weight and xDrive prevents any wheel spin on the Gran Coupe.
I definitely have a good amount of lag. When I'm at full stop and I hammer down on the accelerator, the car sits idle and hesitates for a fraction of a second. After having tried different scenarios, it seems nothing can circumvent this.
Even when driving along and I need to suddenly accelerate, if I hammer down the car will hesitate before launching itself
