This is how it's done in Django 1.10. Just override get_form and return add_form when object is None:

class FoobarAddForm(forms.ModelForm):
    class Meta:
        model = Foobar
        fields = ['some_field',]

@register(Foobar)
class AdminFoobar(admin.ModelAdmin):
    add_form = FoobarAddForm

    def get_form(self, request, obj=None, **kwargs):
        defaults = {}
        if obj is None:
            defaults['form'] = self.add_form
        defaults.update(kwargs)
        return super(AdminFoobar, self).get_form(request, obj, **defaults)
