Rush by committee to produce instrument panel (9)
I believe the answer is:
dashboard
'instrument panel' is the definition.
(dashboard is a kind of instrument panel)
'rush by committee' is the wordplay.
'rush' becomes 'dash' (dashing is a kind of rushing**).
'by' says to put letters next to each other.
'committee' becomes 'board' (board is a kind of committee).
'dash'+'board'='DASHBOARD'
'to produce' is the link.
(Other definitions for dashboard that I've seen before include "Part of estate, maybe" , "What has controls in place" , "Instruments found here" , "control panel" , "Car's instrument panel" .)
