The Mercedes AMG Formula 1 team's 2017 season has been a successful one thus far and, three and a half years after making its debut, the Mercedes-AMG Formula One Power Unit has achieved a conversion of more than 50% during dyno testing in Brixworth.
Basically, it now produces more power than waste energy, a remarkable milestone for any Hybrid, let alone a flat-out racing engine.
In the video below Owen Jones, Head of Performance & Control at Mercedes-AMG High-Performance Powertrain discusses how significant 50% thermal efficiency is in the racing.
The recent dyno tests showed a 1.6-litre turbocharged V6 scored in excess of 50% thermal efficiency; more than half of available energy in a fuel is now doing useful work, not simply being wasted as heat and nose. Many engines only achieve around 35% thermal efficiency.
Owen says Mercedes spent a lot of time on the fundamental thermal dynamic principles such as the gas exchange processes and combustion.
The best part of it all is that the powertrain will end up on the road. The Mercedes-AMG Project One will feature the version of the engine detailed in the video, so be sure to take a closer look.
