Car part the Brits call a "wing" (6)

I believe the answer is:

fender

(Other definitions for fender that I've seen before include "Boat impact protector" , "Ship's protection against impact" , "Feature of vehicle from 24 [US SAY]" , "Guard, around a fireplace perhaps" , "Ship's side protector" .)

I've seen this clue in The New York Times.
