To me the slalom runs are the ultimate test of a REAL sports car, as it shows the handling of the car. Its nice to have rapid acceleration, which any vehicle under 4.5 seconds will feel impressive, but doing a slalom, or driving on a super curvy mountain road with 90 to 180 degree switchbacks and turns, you will immediately feel the handling abilities of your car....the ultimate test for an onroad sports car.
I'd be so so happy if the Taycan handled better than the 911 GTS
But I really think that the weight of the battery pack won't help Porsche. It handles really well, but I think it would help them to really become radical with weight saving
