Sports vehicle tours in escapade (5)
I believe the answer is:
caper
'escapade' is the definition.
(I've seen this in another clue)
'sports vehicle tours' is the wordplay.
'sports' becomes 'pe' (Physical Education).
'vehicle' becomes 'car' (car is a kind of vehicle).
'tours' is an insertion indicator (to tour can mean to go around).
'pe' going into 'car' is 'CAPER'.
'in' is the link.
(Other definitions for caper that I've seen before include "that may be cut by the energetic?" , "Pickle ingredient" , "Escapade with an edible bud?" , "Frolic - sauce!" , "Frolic - bud used in cooking" .)
