A red 2009 Chevrolet Camaro sits under a light tan tarp in the center of an unmarked design studio in suburban Detroit. General Motors doesn't want visitors to this studio, tucked away in a supplier's factory far from GM's main design centers, to learn too much about plans to accessorize the Camaro.
Still, an observer can see the outline of a huge wing on the trunk lid. Designers are sculpting in clay a set of aerodynamic lower body panels with a finned lower fascia where the exhaust pipes exit under the rear of the car. With these accessories, the Camaro takes on an even more sinister look.
GM's designers here are creating many of the items that eventually will turn up at dealerships to be sold to buyers wanting to make their new vehicles unique. A lot of new-car buyers want to do that.
