Yep
It's probably helpful to look at the other design derived from the same original designer - Porsche
Most Porsches, particularly pre-2000 have a similar profile of a sharp bonnet to windscreen transition and forward glasshouse that allows 3D flow around and over it, yet the aerodynamically superior porsches consistently have either a more gradual glasshouse/tail incline (less verticle energy in the airflow) or a larger dead area at the rear.
The second seems easier to achieve, probably with a horizontal deflector
