The upcoming changes to Formula 1 power unit regulations could represent good news for Audi. If Audi’s MGU-K has been slightly lacking in terms of outright power delivery, the new limitation on the electric component could help partially reduce that gap. While Audi’s first Formula 1 power unit has earned positive feedback, its current package still does not match the peak power levels of the leading manufacturers.
According to internal sources, Audi had already started developing prototype versions of its 2027 power unit specification several months ago, with the clear objective of overtaking its rivals. The development priority is straightforward: extracting more energy from the internal combustion engine to compensate for the reduction in electric power imposed by the revised regulations.
In absolute terms, Audi’s power unit is not far from Ferrari’s, but some important differences are emerging in how energy is delivered. Audi appears to have less effective energy deployment and, compared to other manufacturers, suffers from a tendency toward less immediate response in the early phases of acceleration.
This is where Ferrari has benefited from its decision to use a smaller turbocharger, giving the Scuderia sharper launch response and quicker low-speed reactions. Audi, by contrast, appears to have favoured an engine map focused more heavily on high-end power output, sacrificing some initial responsiveness in the process.
That engineering choice also creates another characteristic. Audi seems to perform at its best in very high-speed sections, where its power unit delivers impressive performance, but gives away some responsiveness during acceleration phases compared to rivals like Red Bull, which is widely regarded as particularly effective in transitions and short bursts of peak power.
The regulatory shift reducing the influence of the hybrid system will help close part of the gap created by the MGU-K deficit, but it does not solve the more fundamental issue of internal combustion engine power output. For that reason, Audi’s 2027 power unit project will focus specifically on addressing that weakness.
Increasing the ability to extract, deploy and manage more performance from the internal combustion engine will be the central target of the next phase of technical development.
In short, Audi starts from a respectable foundation, but not yet one that matches the best manufacturers in terms of peak power and responsiveness. The 2027 regulation changes offer a real opportunity to relaunch Audi’s competitiveness—provided development delivers an internal combustion engine capable of closing those remaining performance gaps.
