Ford – Probe V
The “80-20 Rule” states that the last 20% of development of a product, activity or organization takes 80% of the total effort expended. There is no scientific basis for the 80-20 Rule. There is only the empirical experience of thousands of managers, developers, athletes, engineers, artists and businessmen who have coped with it in work and life. It’s a good bet that Dennis Connor, Chuck Yeager, Robert McNamara and Sir Edmund Hillary all would recognize and acknowledge the 80-20 Rule. It applies to the Ford Probe series, too. Probe V is the final advance in that series of aerodynamic concepts. It achieved a 10% reduction in drag coefficient, achieving 0.137 to Probe IV’s 0.152. This tiny, but very significant, 10% reduction in drag required building a whole new concept to achieve it.
