Case Studies

When Mark Gerisch decided to make the Romulus Predator a true supercar--an exciting, aerodynamically sleek vehicle with a top speed in excess of 200 mph--he knew he needed to update the traditional methods he had been using to build replicas of classic cars.

The Predator started as a collaboration between Gerisch and Ron Sims, a GM stylist, that resulted in a clay model of the Predator body. Wind tunnel testing showed the design to be aerodynamically viable, so the work of refining the shape of the car began (see Fig. 6.38). Instead of building multiple physical models to visualize changes, the clay model was digitized and transformed into a surface model using ICEM Surf.
