Former F1 driver takes pole position in shade (6)
I believe the answer is:
sienna
'shade' is the definition.
(I know that sienna is a type of shade)
'former f1 driver takes pole position' is the wordplay.
'former f1 driver' becomes 'Senna' (Ayrton Senna, 1960-1994).
'takes' is an insertion indicator.
'pole position' becomes 'I' (I resembles 1 - pole position can mean first place).
'senna' going around 'i' is 'SIENNA'.
'in' is the link.
(Other definitions for sienna that I've seen before include "Earth colour, may be burnt" , "Italian city and brownish pigment" , "colouring" , "Type of earth used as pigment" , "Medieval Tuscan city" .)
