Latest style of gear shift (4)
I believe the answer is:
rage
'latest style' is the definition.
'rage' can be an answer for 'style' (rage is a kind of style). I am not sure about the 'latest' bit.
'gear shift' is the wordplay.
'shift' is an anagram indicator.
'gear' with letters rearranged gives 'RAGE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for rage that I've seen before include "Cult - passion" , "Violent anger, maybe on road" , "Craze, fad" , "Terrible temper" , "Uncontrollable anger" .)
