by New Porsche Hybrid Technology
Porsche has patented a hybrid system that uses a compact axial flux motor. These new engines are lighter and more powerful compared to radial flux ones. Similar technologies are already being used in hybrid models from Ferrari, Lamborghini, and McLaren.
Current Achievements and Future Developments
The new 911 Carrera GTS T-Hybrid and 911 Turbo S models have received positive reviews for their outstanding performance and use of innovative hybrid powertrains. However, Porsche is not resting on its laurels and, as recent patent applications show, is already working on a more advanced hybrid system that could be lighter and more powerful.
Currently, Porsche’s hybrid models, including electrified versions of the Cayenne and Panamera, are equipped with a radial flux electric motor integrated into the housing of the eight-speed PDK transmission. A patent application filed with the World Intellectual Property Organization indicates that Weissach engineers are researching an even more advanced system using an axial flux motor located between the engine and the gearbox.
Advantages of Axial Flux
Axial flux motors in the automotive industry were developed by the British company YASA, which is now owned by Mercedes-Benz. Their motors are also used in cars such as the Ferrari SF90 and 296 GTB, as well as the Lamborghini Revuelto and Temerario. McLaren uses these motors for the Artura models and the W1 hypercar. The latest YASA axial flux motor, introduced this year, produces 1005 hp, is just three inches thick, and weighs only 28 pounds.
Unlike competitors, Porsche does not plan to use motors from YASA and appears to be developing its own versions. This is a complex task, but given the advantages they offer, the company believes the investment is worthwhile.
Technical Features and Prospects
The patent application states that the motor will be housed in its own casing and designed to work exclusively with a two-speed transmission. As experts note, the updated cooling system will help maintain the optimal temperature of the electric motor.
It is unknown when this technology will be ready for series production, but it could allow Porsche to retain the naturally aspirated flat-six engines used in the 911 GT3 and GT3 RS models without resorting to turbocharging. Previously, Porsche confirmed that future generations of these cars will use electrification or turbochargers.
The development of hybrid technologies at Porsche demonstrates how automakers are adapting to environmental and performance requirements. The use of axial flux motors could become a key step in reducing weight and increasing efficiency, which is particularly important for sports cars where every kilogram matters. This innovation also highlights the trend towards in-house development of critical components, allowing companies to control the quality and uniqueness of their products.
