Mercedes left the paddock buzzing in Miami after Kimi Antonelli stormed to his first Formula 1 pole position during Sprint Qualifying, becoming the youngest driver in F1 history to start from the front in any format.
But the teenager’s success wasn’t just about talent — it came on the back of key aerodynamic developments to the W16 that appear to be unlocking performance at just the right moment.
While the Miami International Autodrome has traditionally favoured cars with efficient straight-line speed and stability in medium-speed corners, Mercedes arrived prepared.
From the first and only practice session, the W16 looked hooked up — and that was no coincidence. The Brackley team introduced a lower ride height configuration for Miami, giving the car more ground effect without overloading the rear axle.
Low-downforce rear wing proves key to W16 pace
Mercedes also ran a new rear wing setup with reduced drag, aimed specifically at circuits like Miami. The updated design featured a shortened movable flap, engineered to decrease drag and improve overall top-end speed without compromising mid-corner balance.
The result was a cleaner aerodynamic profile that worked in harmony with the lower chassis setup.

This configuration allowed Mercedes to keep their rear tyres in the optimal temperature window — a problem Ferrari and others have struggled with in similar trim. The stable tyre performance was further complemented by a decision to focus on longer runs during practice.
Both Antonelli and George Russell skipped soft-tyre simulations to concentrate on understanding degradation and fuel load behaviour on the medium compound, which has been rebranded from the more fragile 2024 soft.
In Sprint Qualifying, the W16’s improved efficiency was evident. Antonelli delivered a lap time of 1:26.482, edging out Oscar Piastri by just 0.045s.
Behind them came Lando Norris, Max Verstappen, and George Russell, showing that Mercedes were able to extract maximum performance without relying on tyre peak or gimmicks.
This marks a turning point for Mercedes, who had struggled early in the 2025 season to consistently challenge McLaren and Red Bull. The engineering efforts, led by a reshaped aerodynamic department, appear to be yielding real dividends — especially in circuits where drag efficiency and mechanical grip are critical.
Antonelli’s composure and raw speed may have grabbed headlines, but it’s the quiet progress in Mercedes’ technical direction that could prove more meaningful over the coming rounds.
