Pure progressive performance

For this, real-world cars are put to the test. Hand-built for testing purposes only, attribute prototypes (AP) are created to assess how well different parts function separately and how they go together. In building AP cars, most of the assembly is done manually. While in the manufacturing phase, production cars will be assembled on automated production lines. Learn about the process of assembly, function, and testing of AP cars in Episode 8 of the documentary series "From Concept to Car."
