Miles up winding drive (7)

Ross

I believe the answer is:

impulse

'drive' is the definition.
(I know that impulse is a type of drive)

'miles up winding' is the wordplay.
'winding' indicates an anagram.
'miles'+'up'='milesup'
'milesup' is an anagram of 'IMPULSE'.

(Other definitions for impulse that I've seen before include "Impel us with sudden urge" , "Maybe unthinking urge" , "Instinctive motive" , "Miles up (anag)" , "Chew" .)

I've seen this clue in The Sun.
