The verdictOur take

The DCF85M is the McLaren F1 limited edition of the ATOMIC DCF850, a cosmetic re-skin with identical mechanics: 205Nm, 3-speed Precision Drive and the same compact 100mm body. It offers no performance gain over the standard tool, just the livery and collectability. We rate it one for the look only; for the same capability, buy the standard DCF850.
