Well, it takes more than small details to bring 0.48 down to 0.30.
But maybe the 0.48 model did not take this in account:

I don't understand why anyone thinks 0.48 is a thing. It's way better than any truck sold today, no cooling package, smooth underside and a kamm back. The styling isn't that different to my 84 Celica and that managed ~0.34 in the 80's - the 'all curves' 94 model only managed 0.32. Today's 'full size' Euro vans manage 0.30-0.36 with a completely square rear.
Hucho shows how much gain can be made just by moving an inch here and there, so unless the 0.48 model is from CAD data it's meaningless. All the model proved is that the roof peak isn't the aero nightmare that it first appears.
