Discover how Mercedes’ innovative F1 hybrid system works, featuring advanced cooling, dual electric motors, and groundbreaking battery technology for ultimate performance.
Mercedes Unveils the Secrets Behind Its F1 Hybrid Tech
Mercedes has pulled back the curtain on its Formula 1 hybrid system, offering an unprecedented look at the technology powering its dominance on the track. With powertrain development frozen until the upcoming 2026 regulation changes, the team is revealing how its sophisticated system functions, providing a rare glimpse into F1’s engineering marvels.
Inside Mercedes’ Hybrid Powertrain
At the core of the system is a combustion engine paired with two electric motors, a high-capacity battery, and cutting-edge power electronics. The first motor, known as the MGU-H, is integrated into the turbocharger. It harnesses energy from exhaust gases and provides instant boost to the engine when the battery allows. This complex component will be retired in 2026 due to its development challenges, which F1 believes have deterred new engine suppliers.
The second motor, the MGU-K, operates in conjunction with the gearbox. It delivers power directly to the rear wheels and captures energy during braking. Unlike the MGU-H, this motor will remain a critical part of the regulations post-2026.
Advanced Battery and Cooling Systems
Mercedes’ video delves into the intricate details of the hybrid system’s battery pack. Composed of approximately 200 individual cells, likely in the 21700 format (21mm in diameter, 70mm long), the battery is housed alongside the inverters and power electronics in a single unit. The entire assembly is cooled by an advanced dielectric cooling loop, developed by title sponsor Petronas. This specialized coolant is electrically non-conductive, ensuring safety and efficiency even in the event of leaks.
A Rare Look Behind the Curtain
Mercedes’ in-depth explanation provides a unique educational resource for those curious about the engineering intricacies of F1 hybrid systems. The detailed focus on components like cooling loops and power electronics offers fans a new appreciation for the complexity of these vehicles.
A Challenge to the Grid
While Mercedes’ transparency sets a high bar, the revelation raises curiosity about how other teams address similar challenges. The innovation and ingenuity across the grid would undoubtedly offer diverse approaches to hybrid powertrain design, further enriching the sport’s technical allure.
This rare insight highlights the advanced technology driving Formula 1’s hybrid era while leaving fans eager to see how the upcoming 2026 changes will shape the next generation of race cars.
