I have always had a great deal of respect for the Ford development engineers, but I have never actually owned a Ford!
When I was 'requested' by Tom Walkinshaw to head up the Jaguar XJ220 development, moving from a nice cosy job in motorsport, I had a couple former Ford guys to help me. Their last project had been the 4x4 Sierra Cosworth.
I learned a great deal from their methodology of road car development and one of the first questions I was asked was what did I want to do about CCD?
I knew what OCD was, but CCD turned out to be Customer Correlated Durability. Ford had developed a program of testing based on real usage of their huge customer base and the development testing reflected this well.
My problem was we had a whole bunch of deposits on cars but no real idea what customers would do with their 220's. In the end and given the compact timescale (in roadcar terms) of the project we formulated a program of accelerated durability run mainly at Millbrook, and something I named SAD.
Simulated Autobahn Durability ran the car through some really high speed (up to 180mph) testing with some heavy braking incidents and sections of low speed for the inevitable road works. The experience of the two Ford guys was a great help in successfully completing these programs.
