This episode of The F1 Racing Narrative breaks down how modern Formula 1 hybrid power units actually work, and why the sport moved to these ultra‑efficient 1.6L V6 turbo-hybrids in the first place.Luke unpacks the key components of today’s power units — from the internal combustion engine and turbocharger to the MGU-K, MGU-H, battery and control electronics — and explains how they work together to deliver over 1,000 horsepower while using far less fuel than previous eras.We then dive into how energy recovery works on track, what drivers feel behind the wheel, and how teams balance performance, efficiency and reliability under the current regulations.Finally, we look ahead to the 2026 power unit rules: the removal of the MGU-H, a much more powerful MGU-K, sustainable synthetic fuels, and what all of that will mean for engine manufacturers, racing strategy, and the future of Formula 1.If you’ve ever nodded along when commentators mention "deployment", "harvesting" or "mode strat" without really knowing what’s going on under the engine cover, this one’s for you.
