In highway patrol pony car parlance, SSP initially stood for Special Service Police when applied to the mighty 1982 Mustang. After evaluating a 1979 Camaro Z28 for an 18-month period, the California Highway Patrol asked The Ford Motor Company to deliver several Mustang notchback coupes for testing. The Ford Crown Victoria sedan was heavy duty enough for police duty, but it was underpowered and couldn't serve as a high speed pursuit vehicle. This is why the CHP had tested the Camaro Z28 and wanted to evaluate the Mustang. For whatever reason the CHP didn't select the Z28.
