Monaco GP 2026 — Weekend annex

The Circuit de Monaco is 3.337 km over 19 corners — the slowest and narrowest track on the calendar, essentially unchanged in layout since 1929. It is the only venue with a tunnel taken flat-out at racing speed (~290+ km/h at the exit before the Nouvelle Chicane). The Fairmont (Grand Hotel) hairpin is the slowest corner in all of Formula 1 (~45-48 km/h). Race lap record: Lewis Hamilton, 1:12.909 (2021, Mercedes). Historically one DRS zone (2011-2025) on the start/finish straight; from 2026 DRS no longer exists and — see below — active aero does not operate here either.

For Monaco, the FIA mandates a circuit-specific engine map named 'Rev 1' (the standard everywhere-else map is called 'Base'). Under Rev 1, the MGU-K's 350 kW peak deployment must start tapering from 200 km/h and reach zero electrical deployment by 300 km/h — so cars get no full electric deployment at high speed, including the tunnel exit. This is tighter than the universal 2026 'Base' taper, which only ramps down from 290 km/h to zero at 355 km/h. The goal is to cap top speed at Monaco's high-speed sections (tunnel) for safety. Overtake Mode is the one residual: with it active a driver still gets roughly +150 kW at 300 km/h, tapering to zero by ~310 km/h — so there is a small electric boost available, but never the full 350 kW at speed.

Monaco 2026 is the first race of the season with no Straight Mode zones at all: active aero does not operate, and cars run with closed (high-downforce) wings for the entire lap. Two reasons: the FIA requires a Straight Mode zone to last more than ~3 seconds and Monaco has no straight long enough; and the tunnel-exit braking zone has too little run-off to allow a low-drag/high-speed configuration safely. Note Overtake Mode (the ex-DRS overtaking aid) technically still exists at Monaco, but in 2026 it is delivered as electric boost, not wing movement — and that boost is heavily capped here by the Rev 1 map. So there is no wing-based straight-line aid; the lap is run on fixed wings.

For the 2025 Monaco GP, F1 trialled a one-off rule forcing the use of at least three sets of tyres of at least two different compounds — a de-facto mandatory two pit stops, intended to inject strategy into a circuit where overtaking is nearly impossible. It backfired: teams gamed it by deliberately backing up the field to open cheap pit windows. For 2026 the WMSC-ratified sporting regulations delete the Monaco-specific tyre-usage clauses from Section B. Free strategy returns — drivers must still use two compounds in dry conditions (the standard season rule), but the second mandatory stop is gone.
