Hungary saw the final update to what effectively amounts to a B-spec version of the MP4-30 introduced at the British round by McLaren - a small twisted fin under the mirror, to better channel airflow to the rear of the car.
From Austria onwards McLaren have heavily evolved their car, with the short nose being introduced there. At Silverstone the new package comprising a front wing, bargeboard and diffuser moved the car on, and now this.
This latest piece appears to complete the programme, which has been inspired by incoming aerodynamicist Peter Prodromou.
