Why are most of the hybrid car designed with a hatchback design rather than normal design?
Just maybe the hatchback has become 'normal'. I think it may also be easier to produce the rear edge that is needed for minimising drag and designers of hybrids are inevitably focuses more on reducing energy consumption
I agree with Aleš: One main target to implement hybrid drive is to reduce fuel consumption. In this way, the design of many hybrid cars has to consider measures, which reduce driving resistances. Besides lowering rolling resistances and the reduction of weight, the reduction of aerodynamic drag has an important impact on the driving resistances of a car, especially at driving speed above about 50 km/h. Due to its advantageous shape in general, hatchback design gives the possiblity to reduce aerodynamic drag.
