CG cars assault us from all angles, whether we know it or not. These days, much of what we see in car spots on television is created from bits of data, not bits of ore. No matter, the renderings are still labor-intensive to produce. For spots, the animators are often working with CAD files provided by the manufacturer's engineering department. The ability to create a CG car out of thin air is a boon to the concept-rendering community as well. An obvious example of CG's capability is the recent Superduty Superbowl ad. Less obvious use of CG can be found in Jeep's "Bigger, Deffer" spot, where the entire Wrangler is assembled out of 0's and 1's.
French digital a rtist extrodinaire Gabriel Rabhi has harnessed processor cycles to create an Audi A7 out of pure conjecture. Of course, there is no such thing as an A7 (yet), but rumors abound. Rabhi created the car as a skill-building exercise, to get a better handle on modelling techniques for complex objects. The multiple facets of an automobile's structure and skin are time consuming and often difficult to model. Cars are created almost entirely out of complex curves, and the only way to geometrically model such an organic form is by using NURBS curves. If it sounds complex, that's because it is.
