Anatomy of an F1 power unit
The 2014–2025 hybrid power unit: a 1.6-litre V6 that made a thousand horsepower and passed 50% thermal efficiency by refusing to waste anything — not the exhaust, not the braking, not even the turbo's spare breath.
F1 stopped calling it an engine for a reason. The combustion V6 is one component of six that trade energy back and forth: two motor-generators, a battery, a turbocharger and its cooling all work as one machine. Follow the blue pipes for air, orange for exhaust, and the dashed teal wires for electricity.
This is the layout that defined the hybrid era. Its cleverest part, the MGU-H, was also its most expensive — the 2026 regulations removed it and roughly tripled the MGU-K’s electric power instead. To understand why that rule mattered, you have to see where the MGU-H sits: dead centre of the turbo shaft.
