The issue for the hood angle would be at the leading edge,not the cowl area.If you'll go the the FLOW-IMAGES thread you'll find many wind tunnel images which illustrate acceptable flow over the windshield in spite of cowl ventilation induction.
The article might mention that the entire car has a bubble out in front of it.This can be clearly seen in any wind tunnel photo.
