How Monza introduced oval-like slipstream racing to F1

The 2026 Italian GP at Monza showcased both the best and worst of F1's yo-yo racing style. Several examples of 2026 regulations changing racing at 24 circuits, but Monza's slipstream festival was most dramatic. New term yo-yo racing: cars complete overtakes with battery but can't break away or hold position as energy depletes. 53-lap Monza most extreme, cars in packs unable to break due to huge tow on long straights boosting electric overtake mode, allowing slower cars to stay with front car. Most obvious with Red Bull's Max Verstappen, lacking power unit to challenge Mercedes for win, but slipstream and 2026 energy deployment kept him with George Russell for long time. Briton unable to break away, became sitting duck whenever Verstappen passed. Verstappen said he didn't enjoy it when people drive by like turtle, overtake mode promising but hard to defend when leading. Even with VSC, boxing better tires, overtaking still too powerful for defense. Oscar Piastri and Lewis Hamilton lost touch before mid-race VSC, formed pocket, same for Lando Norris and Pierre Gasly. Veteran oval drivers trade lead, but on F1 road course harder. Russell and Verstappen cost each other time for Kimi Antonelli spectacular comeback. Andrea Stella: Not easy to complete overtake and move on with regulations. Took time for Lando to pass Gasly and close gap. Entertainment but issues for quicker cars if not front grid. Fred Vasseur: Race pace okay-ish, main issue top speed and overtaking impossible to attack or defend. Attacking drains battery, next straight loses position. Stella: Very busy optimizing strategy and setup for new racing style dominating conversation on energy-hungry circuits. Managing power unit and battery key. Slipstream with faster car struggles to pull from slower. Could make half second difference per lap. Monza 2026 remembered as most relevant race with new regs, high execution quality. Mercedes had step advantage. Antonelli only one bucking pack trend, marched from 19th. Did hard work early, ran as high as sixth after lap 6 restart for unlikely win. Progress due to Mercedes energy deployment, but only one moving groups shows credit. Aggressive but meticulous overtaking. Differentiator ability through traffic. Lewis did it before, Kimi has shown. Driver and car one, nothing stops.
