There’s just three races remaining after this weekend’s Sao Paulo Grand Prix but the development race is showing no sign of slowing down.
McLaren has a new rear wing in Interlagos, one of just two teams with new parts.
The constructors’ championship leaders have a circuit-specific upgrade for the nuances of a circuit with long straights and a tight infield—features that require compromising downforce across the lap.
McLaren
| Updated component | Primary reason for update | Geometric differences compared to previous version | Brief description on how the update works |
| Rear Wing | Circuit specific -Drag Range | Redesigned Medium-Downforce Rear Wing | Suitable to the isochronal of this circuit, a new rear wing assembly has been designed, increasing overall wing efficiency over the existing medium downforce wing. |
| Beam Wing | Circuit specific -Drag Range | High Downforce Beam Wing | As required by the difference in rear wing design, a new beam wing, suitable for the new medium downforce rear wing mainplane and flap has been designed to maximise overall load generated by the assembly. |
| Beam Wing | Circuit specific -Drag Range | Low Downforce Beam Wing | To complement the new rear wing assembly and to extend the range of circuits where the achieved load and efficiency is suitable, a less loaded beam wing has been designed. |

| Front Suspension |
Performance -Mechanical Setup | New outboard suspension pick up points | The new OB suspension provides more freedom in our mechanical setup. Re-optimized suspension fairings around this kinematics and the latest front wing are part of the update. |
| Beam Wing | Circuit specific -Balance Range | Tandem Beam wing | A new beam wing configuration which increases the efficiency of the beam wing system has been brought to this event. |
