Mercedes vs Ferrari telemetry comparison reveals SF-25 weaknesses | Singapore qualifying. Mercedes W16 turns limits into strengths at Marina Bay.

George Russell (Mercedes W16), race start 2025 F1

The comparison between George Russell, pole-sitter at Marina Bay, and Lewis Hamilton, the best Ferrari finisher in sixth, delivers a clear lesson: the Mercedes W16 turned its limits into strengths, while the Ferrari SF-25 remains trapped by mechanical and aerodynamic stiffness.

Sector 1 – Controlled aggression

The first sector of Marina Bay, up to the braking zone of turn 7, is traditionally the fastest part of the lap, with short straights and sharp braking. Here, Mercedes’ character is evident: Russell maximizes traction out of turns 3 and 5, maintaining a constant throttle that stabilizes the car before fully committing. The W16’s speed graph (blue line) is smoother, while Lewis Hamilton’s SF-25 (red line) shows micro-instabilities on throttle release, causing a less stable exit and weaker traction.

In terms of throttle and RPM, George Russell delays full throttle gradually and smoothly, whereas Lewis Hamilton experiences sharper spikes, reflecting the SF-25’s difficulty in mid-corner support. By the end of sector 1, Russell has already gained nearly three-tenths thanks to cleaner control and superior stability.

Ferrari suffers from higher mechanical stiffness and a too-aggressive front response under low-speed braking. The W16, with a front suspension setup likely exploiting more anti-dive, manages load transitions better without inducing understeer.

Sector 2 – Traction and balance dominance

The central sector, technical and twisty, is the true test of drivability. Between turns 8 and 14 lies the heart of lap time. Mercedes built its pole advantage here, also aided by Max Verstappen being slowed by Lando Norris during his final flying lap.

George Russell maintains cleaner exits in nearly every corner, with constant throttle application. Lewis Hamilton frequently has to lift or modulate throttle, especially out of turns 10 and 13, as the SF-25 tends to “push away” the rear. Mercedes delivers hybrid power smoothly to the ground, while Ferrari loses energy to wheelspin and minor corrections. RPM graphs also highlight Mercedes’ stability, with fewer fluctuations and linear throttle response, enabling Russell to shift early and maintain torque through short straights. Lewis Hamilton, conversely, requires micro-corrections, losing valuable tenths.

Gear usage also differs: George Russell uses a shorter mapping in second and third gear for better low-end push, while Hamilton remains in higher gears to reduce slippage, indicating a more sensitive rear end. The delta time shows Russell gaining another two-tenths, reflecting confidence in corner entry and traction. Ferrari shows structural limits: too stiff in mechanical balance and cautious in power delivery. W16 has found the balance: stable downforce, optimized thermal management, and a chassis that follows the driver’s rhythm.

Sector 3 – Efficiency and residual traction

The final sector, from the long back straight to the last chicane, emphasizes efficiency and tire management. Russell consolidates his advantage here. Peak speeds before and after turn 14 are almost identical, but differences arise in hybrid energy use. Russell applies throttle smoothly and steadily out of turn 14, while Lewis Hamilton “snaps” the engine torque, creating micro-traction losses. Mercedes maintains impeccable power progression, balancing delivery and aerodynamics.

The final delta stabilizes at -0.530s, with most gains in sectors 1 and 2, consolidated in sector 3. This highlights not only raw performance but also W16’s consistency and grip retention. The SF-25 struggles with a more unstable rear and reduced thermal efficiency in the rear tires.

Mercedes vs Ferrari: lessons to learn

George Russell’s pole at Singapore is more than driving brilliance: it reflects a Mercedes that understands and adapts. Where the W15 in 2024 was nervous and unpredictable, the W16 demonstrates technical maturity, balance, and controlled traction. A project can adapt and excel even on challenging tracks like Marina Bay.

Ferrari must learn from this growth. The SF-25 remains slow over a single lap and too stiff for high-grip, right-angled circuits. The W16 shows the way forward: smoother responses, less extreme load, and a chassis that “listens” to the driver. But for 2025, it may already be too late, with focus shifted to 2026. Maranello has effectively conceded, and minimal improvements are expected for the remaining races.

Singapore, with its luminous, suffocating embrace, revealed a truth: technical victories arise from harmony, not raw power. Mercedes found that harmony at Marina Bay; Ferrari, which arrived with hope, continues to struggle with ineffective setups and penalizing technical choices. Leclerc hinted at one persistent SF-25 issue: ride height.
