Mercedes GPS exposes Ferrari SF-26 flaw that slows Charles Leclerc and Lewis Hamilton in every turn. Ferrari SF-26 weaknesses laid bare by Mercedes data.

Data collected from the first two rounds of the 2026 Formula 1 season in Australia and China has revealed a significant weakness in the Ferrari SF-26 under traction, especially when compared to the dominant Mercedes W17. Analysis from GPS telemetry shows that this deficit is consistently costing Lewis Hamilton and Charles Leclerc valuable lap time in nearly every corner.

The 2026 season has started as a clear two-horse race, with Mercedes and Ferrari setting the benchmark, while teams like McLaren and Red Bull have struggled to consistently challenge for podiums. George Russell and Andrea Kimi Antonelli have delivered a perfect opening to the season for Mercedes, firmly leading the drivers’ standings and establishing the Brackley team as the team to beat.

George Russell currently leads Andrea Kimi Antonelli by four points at the top of the standings thanks to victories in the Australian Grand Prix and the F1 Sprint in Shanghai. Andrea Kimi Antonelli secured his first Formula 1 Grand Prix victory at the Chinese GP, but he had finished second in Melbourne and only fifth in the Shanghai Sprint, leaving a slight gap in overall points.

Charles Leclerc battled fiercely with George Russell in Australia, challenging for the lead of the race, but strategic decisions by Ferrari under the early virtual safety car meant he ultimately finished third. Meanwhile, Lewis Hamilton earned his first podium for Ferrari in China, finishing third in the Grand Prix and also taking third place in the F1 Sprint, signaling that the seven-time world champion is regaining confidence in the SF-26.

GPS telemetry highlights Ferrari’s traction deficit under acceleration

According to Auto Motor und Sport, GPS data from Australia and China shows the Mercedes W17 consistently generates superior traction under acceleration, giving George Russell and Andrea Kimi Antonelli a decisive advantage over Lewis Hamilton and Charles Leclerc. While the Ferrari SF-26 allows the Italian team’s drivers to match Mercedes through initial turn-in phases and even appear competitive in medium-to-high speed corners, the W17’s superior grip means Mercedes can pull away in every acceleration zone.

At the Albert Park circuit, Charles Leclerc finished 15.519 seconds behind George Russell, while Lewis Hamilton ended the Chinese GP 25.267 seconds adrift of Andrea Kimi Antonelli. Qualifying times also reflected this gap, with the Ferrari pair posting slower sectors by 0.809s and 0.351s respectively. GPS telemetry pinpoints that the primary time loss is in the traction phase out of corners, where Mercedes is able to maximise exit speed more efficiently.

Ferrari upgrades aim to close the gap in traction and tyre management

Ferrari engineers are working on several aerodynamic and mechanical upgrades designed to limit the SF-26’s traction disadvantage. These upgrades aim not only to recover lap time lost under acceleration but also to improve tyre wear, an area where Mercedes has shown clear superiority. Managing Pirelli tyres effectively has allowed George Russell to pull away mid-stint in China, even after initially struggling with traffic and battling both Ferrari drivers after the safety car.

The telemetry shows that while Ferrari can compete through corner apexes, the W17’s traction allows Mercedes drivers to accelerate earlier and maintain higher exit speeds. This creates a cumulative advantage over the course of a lap and ultimately the race. For the Maranello team, closing this gap will be critical to challenging Mercedes consistently throughout the 2026 season.

Japanese Grand Prix: a critical test for Ferrari’s traction upgrades

The upcoming Japanese Grand Prix at Suzuka represents the first major test for Ferrari’s planned upgrades. Lewis Hamilton and Charles Leclerc will need to extract every ounce of traction from the SF-26 to match the lap times of George Russell and Andrea Kimi Antonelli in qualifying. With Suzuka’s mix of high-speed corners and technical sequences, traction out of every turn could prove decisive for both grid positions and race pace.

Mercedes’ ability to maximise corner exit speed remains a key factor in their dominance, and unless Ferrari can significantly improve traction under acceleration, the SF-26 may continue to lose ground in critical phases of every lap. The upgrades being tested in Japan will therefore be closely scrutinised by engineers, pundits, and fans alike, as Ferrari aims to reduce the W17’s advantage and keep the championship battle alive.
