In an automotive landscape increasingly leaning towards electrification, Ferrari remains steadfast in its thermal roots. The prancing horse has recently filed a patent for a Y-configured 12-cylinder engine, a surprising setup that could redefine certain standards. This bold choice, far from being trivial, raises crucial questions about the future of sports powertrains.
A Tradition Revamped
As emissions regulations tighten and taxes penalise polluting vehicles, Ferrari persists in developing its iconic 12-cylinder engine. At first glance, one might think this type of engine is destined for extinction. Yet, the brand continues to integrate it into its lineup, notably in the 12Cilindri model, much like Lamborghini with its Revuelto. The shift to hybrid technology is now essential to prolong the life of thermal engines, but Ferrari has chosen to start from scratch to design an entirely new architecture.
Drawing on decades of experience with various V12s — including the flat engine of the 1980s Testarossa — Ferrari has recently submitted a patent application to the US Patent and Trademark Office (USPTO) for a Y-engine, a novel configuration that warrants attention.

The Y-12 Engine: How Does It Work?
While W engines from the Volkswagen group may seem exotic, Ferrari’s Y12 takes originality a step further. In this configuration, the two banks of cylinders are not physically connected. They could almost be considered as two inline six-cylinder engines operating simultaneously. Each has its own crankshaft and valve timing. The exhausts are directed inwards and converge towards the rear, forming a Y shape when viewed from above. This layout makes it impossible to install a conventional gearbox.
The primary purpose of this engine is clear: it will solely serve as a power generator to recharge batteries intended to power electric motors that drive the wheels. An interesting aspect is that both engines can operate simultaneously but at different RPMs. To satisfy motorsport purists, this innovation is accompanied by a virtual transmission inspired by the S+ Shift of the Honda Prelude. An unexpected comparison that shows Japanese technology can sometimes be compelling.

A New Engine: Why Bother?
In principle, a V6 or V8 could have fulfilled the same role as this Y engine while saving on development costs. However, the choice of a Y engine is not trivial. This architecture offers several advantages: its wide base and tapered top not only optimise under-bonnet space but also improve weight distribution. By moving the weight of the engine block forward, it also frees up more space at the rear of the vehicle for better suspension and effective aerodynamic elements.
That said, for now, it remains unclear which model will host this Y12, or whether its integration is imminent. The mere fact that a patent has been filed does not guarantee that vehicle development is already advanced.

A Look to the Future
This Y engine could mark a turning point in how Ferrari envisions its future models. By combining a well-established tradition in the brand’s DNA with an innovative approach to environmental challenges, the Italian firm could appeal to thrill-seekers while adhering to ecological standards.
In this quest for balance between performance and sustainability, Ferrari seems determined to prove that even in a world where electric power is taking precedence over thermal, there is still room for bold and original technical solutions.
In Summary
- Ferrari is developing an innovative Y-configured 12-cylinder engine.
- This architecture aims to serve as a generator for hybrid systems.
- The banks of cylinders operate independently, each with its own crankshaft.
- Integration into a future model remains uncertain.
- Ferrari seeks to blend tradition and innovation in the face of ecological challenges.
