design analysis , numerous generations of prototype vehicles are made and tested . Such testing is actual field perform

ance testing which simulates actual use and forseeable misuse .

Improvements are integrated in succeeding generation proto types . Similarly further testing is performed on preproduc tion units to ensure the model is designed to the current state of the art for safety , reliability and performance .

Exhaustive quality control efforts are performed on produc
