Fashionable article on NE racetrack feature (7)
I believe the answer is:
chicane
'racetrack feature' is the definition.
(a double bend in a race track)
'fashionable article on ne' is the wordplay.
'fashionable' becomes 'chic' (I've seen this before).
'article' becomes 'a' (indefinite article).
'on' means one lot of letters go next to another.
'chic'+'a'+'ne'='CHICANE'
(Other definitions for chicane that I've seen before include "Series of bends of motor-racing track" , "Short section of sharp bends on a motor-racing track" , "Sharp double bend as obstacle" , "Double bend obstacle on racing track" , "This bridge hand might not make one" .)
