DIRAVI
DIRAVI is the name given by Citroën to its proprietary power steering system, first seen in 1970.
==Name==
DIRAVI is an acronym for "Direction à rappel asservi" literally meaning "steering with controlled return" more accurately described in English as "power steering with power assisted return". In the UK, it was marketed as VariPower and in the U.S. as SpeedFeel.
==Purpose==
This was the first commercially available variable assist power steering arrangement, allowing the motorist power assist when parking, but recognizing that less steering assistance was needed at high speed. This feature
