In other words, it now produces more power than waste energy – a remarkable milestone for any Hybrid, let alone a flat-out racing engine.Owen Jones,Head of Performance & Controls at Mercedes-AMG High Performance Powertrains, explains how it works.
The unit responsible for the Mercedes’ F1 engines, discusses how significant 50 percent thermal efficiency is in the racing.Thermal efficiency is a potential energy burned in gasoline. Engines, therefore, must extract and as much useful work, or power, from fuel as possible.
One of these aids the engine in driving the rear wheels while the other is used to spool up a turbocharger.The best part is that this same powertrain will end up in the road car!
