That's the Mission E Cross Turismo concept which was presented in 2018.
As you can see it looks quite like the Taycan.
When I talk Taycan and not Mission E, I like to call it Sport Turismo like the nomenclature of the Panamera.
I was referring to the window line. It will be exactly like the Cross Turismo. Which is the Sport Turismo on stilts... If you remove the 2 lights on the hood, and the plastic around the wheels, you get the final product.
