When Method 1’s floor impact revolution first got here into impact at the start firstly of the 2022 season, the purpose was easy: Permit for nearer, higher racing.
By attempting to provide chasing drivers extra of an opportunity in opposition to the dreaded ‘soiled air’ impact – the invisible drive discipline that stops drivers from getting shut resulting from aerodynamic disturbance on their very own vehicles – there must be extra alternatives for drivers to try overtaking strikes and, thus, enhance the standard of racing.
For over a decade main as much as 2022, the game had relied closely on the divisive Drag Discount System to assist in giving drivers a greater likelihood to overhaul. Allowed solely in pre-determined sections of the monitor and solely when inside one second of a rival automobile, DRS has produced many a whole lot of passing strikes through the years, however, as many would argue, at the price of driver talent. In spite of everything, why try a daredevil dive to catch an opponent unaware, when you may sit and wait till the DRS zone to press a button after which breeze by on the straight.
For the beginning of F1’s new floor impact period, DRS remained at it had been the earlier season in 2021. The reasoning was not simply to assist present a direct comparability between new vehicles and previous, however as a result of the shift to underbody-dominant downforce meant much less overbody drag than with the 2021 vehicles. As such, the pure slipstream impact of following behind one other automobile on a straight was lowered, with a weaker tow probably making it tougher for drivers to get by on straights.
Nevertheless, the FIA’s head of aerodynamics Jason Somerville advised that the brand new technical rules may ultimately result in the demise of DRS.
“I believe DRS, for us, is a really tune-able function,” he stated throughout an interview with Peter Windsor. “It’s very circuit-dependent and it may be dialled out and in.
“I believe most of us really feel, longer-term, we’d very very like to try to part DRS out if we are able to. However we didn’t assume that was essentially going to be the appropriate factor to do in a single day for these rules.”

Two-and-a-half years into the brand new rules, there may be lastly an finish in sight for DRS – however not beneath the present guidelines. Whereas the overtaking assist will likely be changed with a brand new ‘handbook override’ energy unit enhance when the revised V6 turbo energy models come into impact in 2026, it’s going to proceed to be a serious a part of racing till then.
That isn’t to say that DRS has remained unchanged over the previous few seasons. Whereas the system nonetheless operates in the identical means, the FIA has made some minor tweaks to a few of the zones round a number of circuits on the calendar in latest seasons.
Nearly all of circuits have seen some modifications to their DRS activation zones within the floor impact period in comparison with their closing races with the earlier technology of vehicles. Suzuka, Shanghai, Monaco, Montreal, the Crimson Bull Ring, Silverstone, the Hungaroring, Circuit of the Americas, Interlagos and Yas Marina have all had their DRS activation zones untouched for the reason that begin of 2022 – though these closing three tracks are but to host their rounds this yr. Whereas each Albert Park and Singapore have each seen important modifications to their format in recent times, they’ve retained the very same DRS activation lengths within the areas of the tracks that weren’t modified.
A handful of tracks have seen at the least one in every of their DRS zones prolonged for the reason that begin of 2022. After the return of the Dutch Grand Prix for 2021, the second and closing DRS activation level on the monitor was moved from the exit of the ultimate banked nook to the beginning, permitting drivers a larger profit when pursuing a rival on the run to Tarzan firstly of the lap. The ultimate DRS zone main onto the pit straight at Mexico Metropolis was additionally prolonged by 158 metres for 2022, whereas Qatar’s sole zone was prolonged for its return to the calendar in 2023.
This yr, two circuits have had DRS zones lengthened in a bid to try to present higher passing alternatives. The primary was at Monza, the place the DRS zone on the pit straight was moved over 100m nearer to the exit of the ultimate nook. Baku additionally noticed its personal zone alongside the pit straight prolonged earlier than September’s race, nevertheless, this was merely reverting the change made the earlier season, when it was shortened by 100m.

Apparently, there have been extra circuits the place DRS zones have been lowered by the FIA within the floor impact period in comparison with the earlier generations of vehicles than tracks the place they’ve been prolonged. The ultimate zone in Bahrain was lowered by 80m in 2023 and remained that means this yr, with 70m additionally chopped off the DRS zone alongside the pit straight at Jeddah. After its inaugural grand prix in 2022, the Miami circuit had two of its three DRS zones shortened, whereas the ultimate one on the pit straight was stored because it was.
This yr, Imola and Barcelona additionally noticed one zone barely lowered on every monitor. Nevertheless, the most important shock was maybe Spa-Francorchamps, which had its most important DRS zone alongside the Kemmel Straight trimmed by 70 metres. That appeared to have an effect on overtaking within the race, with solely 25 on-track overtakes in 2024 in comparison with the earlier season with an extended DRS zone alongside Spa’s longest straight.
However whereas DRS zones are getting smaller extra usually than they’re getting longer, there’s additionally extra of them. The 2021 season noticed a grand whole of 46 DRS zones over the 22 rounds on the calendar, rising to 49 for 2022 after which 50 final season. By the primary 18 rounds of the championship, drivers have had a complete of 42 DRS zones at their disposal – a better price than any of the earlier three seasons, helped by fourth zones added to each Albert Park and Singapore.
Assuming that every of the ultimate six rounds retains equivalent DRS zones to final yr, that can convey this yr’s whole to 54 zones over the 24 circuits – simply barely fewer on common than 2023.
It’s clear that the system will stay in use liberally till these present rules are changed after subsequent season. Will the FIA’s objective of “nimble” vehicles succeed the place the 2022 designs failed? The actual fact they’ll embrace a substitute for DRS signifies they count on not.
