Engineering goals are typically rooted in addressing the functional needs of a product. While these engineering goals and specifications can be important in consumers' buying decisions, many times the first impression of the product comes from judgments of the product's aesthetic form. For this reason, this paper set out to study how well human judgment of performance based on a car's shape correlates with the actual measured performance of the car's shape, and what features of the car's shape most influence this judgment. More specifically, participants were asked to rate how aerodynamic, sporty, fuel efficient, and rugged a computer generated car design appeared to them, and these ratings were analyzed against the actual aerodynamics of the vehicle as well as key indicators of sportiness and cornering stability such as center of gravity and wheel stance. The inter-rater consistency of human judgments was also studied.
