A look at the SF70H’s diffuser - note also the extreme angle of the crash structure tail.

As the Mercedes mechanics conduct a front wing change, it exposes the detail under the nose, including the large v-shaped ‘S’ duct inlet.

Flo-viz applied to a new diffuser being tested by Ferrari on the first day of the post GP test. The central portion of the diffuser is now sinuous, having previously been squared off.

Renault continue testing with a new front wing that was run during the lead-up to the Hungarian GP. Huge kiel probe arrays were also mounted behind the front wheels of the RS17 to collect data on the wake being shed.

McLaren continuing to run the triple-element T-wing and revised monkey seat introduced a few days ago for the Hungarian GP.

Toro Rosso's lower-hooped T-Wing, first seen in Baku, features its own reverse swan-neck support and seems oddly angled down - which is likely done in order to work the rear wing harder. A pitot tube has been mounted ahead of the endplate louvres too, as the designers look for more data on their behaviour.
