fast,the original VW Rabbit/Golf was tested with different rear shapes.
* The as manufactured car is Cd 0.42.
* Same car with 23-degree hatch slope is Cd 0.40.
* Same car with 28-degree hatch slope is Cd 0.44.
* Same car with 10-degree hatch slope is Cd 0.34.

If you place the Rabbit under the Aerodynamic Streamlining Template,the 10-degree hatch happens to fit the Template exactly.

If you were to extend the back of the Festiva no more than what VW did at the hatch,and 'relax' the roof slope such that it fit the Template,you might expect a similar benefit.You'd bring the sides in too as WeatherSpotter has done on his tail.
