George Russell reckons System 1’s sliding scale for aerodynamic testing ought to be based mostly on factors, relatively than by place, because the allocations for aero simulations had been reset after the Austrian GP.
System 1’s aerodynamic testing rules dictate the quantity of wind tunnel time and computational fluid dynamics (CFD) capability that can be utilized for an “aerodynamic testing interval” (ATP) of two months, based mostly on championship place.
It is a sliding scale, the place the staff that finishes first within the championship begins a brand new season with 70% of the baseline allowance, in 5% increments as much as the 115% multiplier for ending tenth, in an effort to create nearer grids.
That is reset in the midst of the yr per the championship order on 30 June, which adopted the outcomes of the Austrian Grand Prix.

Mercedes has benefitted from this rule; after ending second in final yr’s championship, it started the yr with 75% of the baseline allowance of aerodynamic testing for the primary three ATPs, however its slip to fourth within the constructors’ standings lifts the staff to 85%.
Because of this the Brackley staff receives 32 extra wind tunnel runs, eight extra hours of “wind-on” time (when airspeed exceeds 15m/s), 200 extra allowable geometries, and 40 hours extra of wind tunnel occupancy. The staff additionally receives a rise of 0.6MAuh within the metric used for CFD laptop useful resource used.
Pink Bull stays on the 70% multiplier because it continues to go the constructors’ championship, whereas Ferrari and McLaren transfer as much as the 75% and 80% brackets.
RB has moved from the 105% multiplier to the 95% bracket because it goes beneath the baseline due to its enhancements this season, whereas Haas has misplaced probably the most. After ending final in 2023’s championship, the American staff was working to the 115% allowance, nevertheless it has now moved to the baseline after taking seventh within the championship from Alpine at Austria.
Alpine and Williams have each gained 10% of their earlier allocations, as Sauber has gained 5% because it sits backside of the constructors’ standings up to now.
The FIA’s technical rules defines the geometries – or restricted aero check geometry – as any illustration of a automotive or a subsection of a automotive to be examined. Making use of a change to their dimensions or to the boundary properties inside is taken into account a brand new geometry, so groups have to be sparing with what number of they use.
Wind tunnel occupancy counts the time that the velocity in a wind tunnel is 5m/s or over, and thus consists of the wind on time. The MAuh pertains to a system outlined within the rules, and consists of processor energy, processor cores, and time for a CFD solver to compute.
Per the desk above, the sliding scale is a inflexible multiplier given to a staff based mostly on championship place, however Russell contends that the multiplier ought to be associated to factors.
Presently, Pink Bull sits on the prime of the championship with 355 factors, over 1 / 4 of the factors scored by all groups. The Briton says that if the multiplier was based mostly on the share of factors, these with a a lot smaller haul might catch up far more rapidly.
“The wind tunnel factor is admittedly good, nevertheless it’s based mostly on positions in the meanwhile, relatively than factors,” Russell outlined.

“Pink Bull have been double the quantity of factors than the second place staff of constructors [in 2023], they usually get the identical distinction in wind tunnel discount as second or third.
“Mercedes to Ferrari final yr, there was solely three factors totally different so perhaps if it is based mostly on variety of factors scored relatively than precise place of a championship, that might assist the staff to catch up faster.”
The present ATP – the fourth of this season – lasts for 10 weeks relatively than the usual eight to incorporate the summer season shutdown. The ultimate two ATPs will cowl the ultimate 16 weeks of the yr between them as much as 31 December, earlier than the allocation is once more reset to 2024’s last championship order.
