The FIA has set the direction for the new engine regulations for the 2021 Formula 1 season, with a larger engine development costs on the top of the poster.
The 1.6-litre turbo V6 hybrid power unit of the formula, which was introduced in 2014, will remain, but with some key changes.
More strict parameters for the design of internal engines are designed to reduce the development costs for engine manufacturers and to “discourage the extreme designs and operating conditions”, while the “high-level” new settings of external told by the FIA to provide teams with a “plug-and-play motor/chassis/transmission swap capacity”.
The dimensional parameters for the turbocharger will also be specified.
In addition, the power unit of the MGU-H to the element, which recovers the thermal energy of the exhaust gas, will be deleted. This will not only reduce the cuts, but also to make the engine more relevant for hybrids, road cars, something F1 has long searched for.
During this time, the MGU-K of the element, which converts the kinetic energy of braking into electrical energy, and then deploys the framework of the acceleration, will be more powerful, with a focus on tactics manual deployment of the additional power of the part of the driver.
The power of the energy storage units will also be standardized for all vehicles, the pursuit of cost reduction.
The new rules also allow for the maximum rev limit to be raised by 3000rpm in an effort to improve the engine sound of something that has been heavily criticized since the hybrid engines have been introduced.
The cost reduction is seen as a key to develop the engine manufacturers in the world of sports. Currently, there are just four: Ferrari, Honda, Mercedes and Renault, but Porsche seems eager to join, while Aston Martin has also expressed interest on the condition that the cost of restrictions are okay. Aston Martin is yet to comment on the FIA announcement.
More details on how the cost reduction will be achieved are yet to be announced by the FIA, but the sport organization of the body views this as an objective and will continue to work on the issue in the course of the next year. Input power teams, engine suppliers and outside experts is all be used to write full proposals.
