If you go back a few pages you will actually see my comments about the F10 design. It wont , repeat WONT be a smaller F01 nor will it be a return to the E39. The F10 like the F01 is an evolution of the current car in this case the E60. The front grille will not be as large proportion wise as the 7er and the headlights will sit above the grille in a similar shape to the E60.
At the rear there is no L shape like the F01 but the cut out in the sloping bumper is there but the overall shape is more like the E60 wrapping around the rear wings but not as wide as todays car which cuts off at the rear screen.
