Mercedes-AMG Petronas F1 Team has officially revealed the first glimpse of its 2026 Formula 1 challenger, dubbed the W17 E Performance. The unveiling marks the beginning of a new era for the team, aiming to capitalize on the significant regulation changes set to redefine the sport.
The W17 aims to propel Mercedes back into title contention after a period where they haven't been challenging for the top spot. The new regulations for 2026 encompass substantial changes to both the chassis and engine, promising a more level playing field and an opportunity for teams to showcase innovation.
One of the most significant aspects of the 2026 regulations is the revised power unit configuration. While retaining the turbocharged 1.6-liter V6 internal combustion engine, a key feature since 2014, the Motor Generator Unit – Heat (MGU-H) will be removed. Conversely, the Motor Generator Unit – Kinetic (MGU-K) will see its output increase dramatically to 470 bhp (350 kW) from 160 bhp (120 kW). The internal combustion engine's power output will decrease to 540 bhp (400 kW) from 850 bhp (630 kW). The new power units are expected to recover twice as much electrical energy as before and will utilize a fully sustainable fuel developed by Formula One.
In addition to the power unit changes, the 2026 cars will feature revised dimensions and aerodynamics. The wheelbase has been reduced to 340 cm from 360 cm, and the width is now 190 cm, down from 200 cm. The minimum mass has also been reduced by 30 kg. The cars will feature new active aerodynamics on the front and rear wings, with the drag reduction system (DRS) being replaced by a new overtake mode. Downforce will be reduced by approximately 15% compared to the 2022-2025 generation of cars.
Mercedes' W17 sports a revised livery, retaining the black and silver scheme with Petronas green accents. A notable addition is the Microsoft logo, reflecting a new multiyear partnership aimed at driving innovation through Microsoft's cloud and AI technologies. The team's driver lineup consists of George Russell and Kimi Antonelli.
Toto Wolff, CEO and Team Principal of Mercedes-AMG Petronas F1 Team, emphasized the importance of innovation and focus in response to the new regulations. He highlighted the team's commitment to long-term development of the power unit and sustainable fuels in collaboration with Petronas. Wolff also expressed excitement about the partnership with Microsoft, stating it would enable faster insights, smarter collaboration, and new ways of working.
However, ahead of the 2026 season, concerns have emerged regarding potential loopholes in the engine regulations. There is apprehension that Mercedes and Red Bull may have found ways to exploit engine compression ratios, potentially gaining a performance advantage. This has led to discussions with the FIA to seek clarification and ensure fair competition.
Despite these concerns, Mercedes is determined to return to title-contending form in 2026. George Russell has expressed his loyalty to Mercedes and his belief that the team provides his best chance of winning a World Championship. The W17 is scheduled to hit the track for pre-season testing in Barcelona, where its performance will be closely monitored.
