Metalcrafters operates out of a small industrial strip in Fountain Valley, a short drive from Disneyland. Using the sketchbooks and other data as a guide, more than 20 departments work together to produce a concept.

Representatives from Metalcrafters met weekly - sometimes daily - with Chrysler representatives via videoconference.

Once they unloaded the clay model from the moving van, workers made a mold by covering the clay with fiberglass and epoxy resin. From that epoxy mold, they constructed a carbon-fiber body. Some parts of the vehicle, such as the fenders and hood, were molded separately. They used sheet metal to join the carbon-fiber body to a chassis derived from two donor vehicles.

By October, the vehicle was ready for the "dry fit" review. It would be Vardis and Wilkins' first chance to see the fully built vehicle. Joining them would be Sgalia, engineering chief Quigley and Kornilov, the engineer.

A big grin spread across Vardis' face when he entered a walled-off area of the Metalcrafters workshop. There sat the Trailhawk, lighted up and covered in silver primer. "It looks so muscular. I can't believe how powerful the stance is," he said. Wilkins' first reaction was that this would be a "dynamite concept." Said Sgalia: "We need a sign: No Wimps."


Nicho Vardis prepares for a review by DaimlerChrysler CEO Dieter Zetsche by applying tape to simulate door cuts and other openings on the vehicle.
Ignoring the din of welding and hammering outside the temporary walls, the team got to work. For the next few hours team members examined the vehicle inside and out. They crouched down to the floor. They climbed on ladders.

Some people think designing is just about drawing, Vardis told an observer. "It's a physical job."

Before long, the designers began placing pencil marks and neon-green dot stickers on the primed surface to mark areas that needed work. Thin strips of electrical tape indicated spots that had to be resanded.

Drawing on his sculptural skills, Vardis started adding clay to the side mirrors, which were deemed too small.

Wilkins had come armed with his sketchbook and a legal pad filled with notes. He climbed onto one of the exposed-foam seats and compared his specifications for the interior with the real thing.

Very little had to be changed. "I think it is very close," Wilkins said. "It exceeded my expectations. If you've only ever seen it in data, there are so many opportunities to have gotten things wrong. Fortunately, there are no major areas where we've miscalculated."

Epilogue

The modifications needed turned out to be relatively minor. In the next few weeks, Metalcrafters would complete its work, including painting and upholstery.

In November, Sgalia and Quigley made one last trip to Metalcrafters. This would be the final chance to make corrections. Fortunately, aside from refinement in the body paint, little needed to be done.

About a week later, the vehicle would be presented to LaSorda, along with other concepts, at Chrysler's Pacifica design studio in Carlsbad, Calif. In the ensuing weeks would come photo and video shoots for media kits.

The vehicle is now ready for its close-up. More than a year after Vardis and Creed first visualized it, the Trailhawk is scheduled to debut today, Jan. 8, at the North American International Auto Show.
