Nine of the 10 Formula 1 teams have confirmed they have brought new parts for this weekend’s French Grand Prix.
Haas, which originally planned to bring a significant upgrade for their VF-22 to this race, delayed that upgrade to next week’s round in Hungary.
McLaren and AlphaTauri have declared the most extensive revisions to their cars this weekend. AlphaTauri’s upgrade is largely focussed on improving the car’s performance in medium and high speed corners, where the team has been at a disadvantage compared to its rivals in recent races.
While McLaren have also brought performance upgrades this weekend, they also have an eye on reliability. While several teams have new cooling options for what is expected to be two hot weekends in France and Hungary, McLaren have also revised their rear wing design to address a reliability concern.
Some teams have also indicated other changes to their cars which do not appear in the details issued by the FIA. The Ferrari-powered teams have a new clutch design which is intended to improve their starts. Mercedes also have a visibly different nose design this weekend.
Here are the car updates declared by each team for the French Grand Prix.
Mercedes
Floor Edge
Reason for change: Performance – local load
Difference: “New rear reduced curvature floor edge ahead of rear tyre.”
Description: “Reduces local floor load by reducing the local camber improving flow into the diffuser, which in turn increases diffuser load.”
Front Corner
Reason for change: Circuit specific – cooling range
Difference: “Addition of internal louvres local to front brake duct exit.”
Description: “Improves how the brake disc cooling flow exits the front cake tin, increasing mass flow through the disc and hence cooling.”
Red Bull
Floor Fences
Reason for change: Performance – local load
Difference: “Revised fence geometries extending to the floor edge”
Description: “The fence layout has changed to re-distribute the local pressure distributions to improve load whilst maintaining the flow stability.”
Rear Corner
Reason for change: Performance – local load
Difference: “Revised upper wing cascade.”
Description: “A revision to the upper winglet cascade to gain local load without disruption to lower wing cascade or the adjacent brake duct exit.”
