All 10 Formula 1 teams have brought updates for their cars to the first race after the summer break.
McLaren has revealed the most extensive upgrade for its car based on information supplier to the FIA. They will test a new rear wing, revised floor and front suspension on their MCL36.
Mercedes will also continue their efforts to steadily improve the competitiveness of their W13. They have brought more changes to the car’s floor as well as the front and rear wings. As is the case for most teams at the high-speed Spa-Francorchamps, the latter is targeted at reducing drag to improve top speed.
Championship contenders Ferrari and Red Bull have also brought new parts for their car. The latter have refined the shape of their rear suspension in order to reduce drag.
F1 teams’ updates for Belgian Grand Prix
Mercedes
Front Wing Endplate
Reason for change: Performance – flow conditioning
Difference: “Reprofiled wing tip elements as they run into the endplate.”
Description: “Improved flow over wing tip by reducing pressure peaks, reducing losses and improving flow to the rear of the car.”
Floor Fences
Reason for change: Performance – local load
Difference: “Floor fence alignment adjustment.”
Description: “Better fence alignment through more conditions, improving the flow that feeds into the floor vortex system and improving local downforce.”
Floor Body
Reason for change: Performance – flow conditioning
Difference: “New reduced chord floor edge wing.”
Description: “Reduced wing chord reduces wing load, this in turn improves flow into the diffuser increasing both floor and diffuser downforce.”
Rear Wing
Reason for change: Performance – drag reduction
Difference: “Reprofiled flap and wing tips.”
Description: “Efficient reduction in wing load which is appropriate for the circuit in Spa where lower drag wing levels are optimum.”
Red Bull
Coke/Engine Cover
Reason for change: Circuit specific – cooling range
Difference: “Mildly re-profiled sidepods.”
Description: “Respecting existing split lines of surrounding parts, the sidepods have been altered to gain cooling range with reduced consequences when opened.”
Rear Suspension
Reason for change: Performance – flow conditioning
Difference: “Rear suspension shroud re-profiled”
Description: “Without any structural alteration, the rear lower wishbone shroud has been re-profiled so as to reduce the local aerodynamic losses downstream.”
