Ferrari's sidepod and engine cover bodywork which is made from one much larger piece, rather than smaller sections as done elsewhere on the grid.

The brake duct design on the Ferrari SF1000 features a two-piece drum, improving the airflows path as it travels across the face of the assembly and out through the wheel rim.

The Haas VF20's floor section ahead of the rear tyre has a different finish, as the team look to improve stability in a region where multiple slots and holes could easily cause it to be damaged.

As a comparison a similar area on the Mercedes W11. Note how they use more horizontal sections to bridge the gap in the middle of the deflector panel.

The Mercedes W11's rear wing assembly and single element T-wing. Also note the single bladed element between the rear wing pillars, above the exhaust. This just helps to tidy up the flow coming off the engine cover before they're influenced by the exhaust gasses.

The Williams FW43's floor has metalwork stitched into the floor around the tyre squirt slots, in order that the floor doesn't flex too much and close the gap, reducing their effectiveness.
