Regulations for the next generation of power units are still being discussed. In 2026, Formula 1 will witness an important turning point in the engines, with a significant increase in electric power, which will move to nearly three times the current values, but above all with the development of alternative fuels that are neutral with carbon dioxide and greenhouse gases. On the other hand, the MGU-H will disappear from the power units, The second alternator is directly coupled to the turbocharger unit. The MGU-H is activated by a turbine, which is in turn powered by exhaust gases, allowing the heat energy normally circulated in the exhaust to be recovered, and converted into an electric form to recharge the battery.
Claudio Lombardi, former head of Ferrari’s engine division with an important past also at Lancia, was recently analyzed on the pages of FormulaPassion.it The different aspects of the 2026 regulations. While appreciating some points, and above all the approach with the energy flow cap and the transition to alternative fuels, Lombardi was highly critical of the removal of the MGU-H: “On the other hand, what is very negative and I am clearly objecting to is the cancellation of the MGU-H. Formula 1, the highest expression of motorsports that could have an impact on standard mobility, is abandoning the search for enthalpy recovery from exhaust gases. I am totally against it, considering that we are one step away from the mass application of devices of this type, which were borrowed as an idea from Formula 1. I refuse to think that a factory like Audi will not succeed in a few years to reach the levels of competition, especially with such This restrictive regulation. If only MGU-H was the problem, it would have been possible to put all participants on an equal footing in 2026 and then leave everyone’s developments on that component open. Technically, this is a negative thing“.
Also thanks to the use of the MGU-H, modern Formula 1 combustion engines have transformed efficiency 32-33% From the latest V8s derived so close to 50% With V6s turbocharged. Removing the alternator of the second engine will inevitably lead to a loss of power, since part of the heat remaining in the exhaust will no longer be recoverable. “I still insist on engine performance, which means enthalpy should not be unnecessarily thrown into the exhaust”Contact Lombardy. “Denying the possibility of sustaining MGU-H means wasting energy, which goes against everything we talk about in today’s world, where we try to save energy. The regulation banning MGU-H is ridiculous and goes against the principles of the European Community Committeesas well as a factor that may decide the premature termination of a heat engine”, The engineer concluded.
