Hood Scoops:

Draw a closed curve in top view to define one scoop area. Mirror the curve and position both over the hood.



Select the car body faces below the curve. Trim the curve with the selected faces. (Don’t trim with the entire car otherwise you’ll cut through the bottom.)

Scale each scoop panel to reduce length by 13” and width by 5". Resize the Z dimension to reduce the curvature (verify in side view) to better match the curvature of the hood.

Center the panels within the openings, then position them just a little toward the front of the car.

In side view, rotate the panels so they drop toward the front of the car. First, reposition the pivot point of the rotate tool to the rear of the panels.

Select edges of scoop and edges of corresponding body opening.
Blend with G2 Continuity and Bulge = 0.25

The images below show the Pivot point moved to the rear of the scoop panels to allow the panels to swing down:







Hood Scoop Grill:
In top view draw a closed curve for the hood scoop grill. Perform Curve > Project to map the curve onto the hood scoop. Be sure the curve has a good size radius on the ends because we need room for the fillet that comes later. Mirror the closed curve onto the opposite hood scoop.



Extrude the projected closed curve a couple of inches (with Both Sides checked). This will be our cutting object.



Select the car body and perform Boolean > Difference using the extraction as the object to subtract. The result is a new surface in the solid car body. Assign a unique Style to this hood grill surface.

Select the surface and Extrude 0.6” (with Both Sides and Cap Ends checked). The result is a solid.



Select the bottom face of the blue solid and Fillet 0.2” with Shape = Const Dist.
Select the car body and Boolean > Difference the blue solid.



Select the hood grill top edge and Fillet 0.34” with Shape = Const Dist.
