Ferrari Patents Radical Dual-Inline-Six EREV System to Create Next-Generation V12 Hybrid

Everyone assumes the traditional V12 engine is facing an inevitable, quiet death, regulated out of existence by global emissions mandates. The common wisdom dictates that supercar buyers will simply have to accept silent, battery-heavy electric vehicles or heavily compromised plug-in hybrids. But newly uncovered patent filings from Maranello prove that assumption wrong. Ferrari is not abandoning its signature twelve-cylinder wail; instead, it is completely redefining what a V12 engine actually is.

According to United States Patent and Trademark Office filings, Ferrari has designed a radical new powertrain that deconstructs the V12 into two separate inline-six engines. For the prospective supercar owner or collector, this represents a massive shift in what they will actually be buying. You aren't purchasing a traditional combustion car, nor are you buying a standard EV. You are buying an Extended-Range Electric Vehicle (EREV) where the gas engines serve entirely as onboard power plants.[1][6]

The mechanism is a pure series hybrid. Unlike the current Ferrari 296 GTB, where the V6 engine physically drives the wheels alongside an electric motor, this new dual-inline-six architecture has zero mechanical connection to the drivetrain. The engines are literal gas generators. Their sole job is to spin, create electricity, and feed it to a floor-mounted battery pack and high-powered electric motors mounted on the rear axle.[1][5]

For the buyer, this solves a critical problem: the heavy, numb feeling of a pure EV. By relying on a series hybrid system, Ferrari can use a much smaller, lighter battery pack than a traditional electric hypercar. The dual inline-six engines provide the sustained energy needed for track days or long grand tours, eliminating range anxiety while keeping the vehicle's center of gravity remarkably low.

But the engineering layout is where the patent truly breaks from tradition. Rather than sharing a single engine block and crankshaft like a conventional V12, the two inline-six engines are mounted independently. When viewed from above, they form a "Y" or "V" shape, angled between 20 and 30 degrees apart.[2][4]

To prevent the two massive electrical generators from fighting for physical space inside the "V", Ferrari's engineers designed the system so that one engine faces forward and the other faces rearward. This allows the generators to sit on opposite ends of the engine bay, optimizing the internal packaging.[2][6]

This Y-shaped configuration isn't just an engineering flex; it has direct implications for the car's physical footprint and aerodynamic profile. By narrowing the rear of the engine bay, designers can channel air more efficiently over the rear diffuser. For the driver, this translates to higher downforce and better high-speed stability without relying on massive, drag-inducing wings.

The most pressing question for any Ferrari purist, however, is the emotional experience. A Ferrari without its signature sound and shifting visceral punch is a tough sell at a half-million-dollar price point. Because generators operate at steady, efficient RPMs rather than revving up and down with vehicle speed, a standard EREV would sound like a droning locomotive.[3][4]

Ferrari's patent directly addresses this fear with a system designed to digitally recreate the traditional sound and feel. The vehicle's computer will artificially spike and drop the RPMs of the gas generators as the driver accelerates, simulating the physical jolt and auditory rise-and-fall of a traditional dual-clutch transmission. The driver pulls a paddle, and the engines instantly change pitch, even though no physical gear was shifted.[3][4]

Furthermore, because the two inline-six engines are not mechanically linked by a single crankshaft, they can operate asynchronously. The engine control unit can run the left bank and the right bank at completely different speeds simultaneously.[3][5]

By carefully tuning the exhaust pulses through a shared, valve-controlled exhaust pipe, the system tricks the human ear into hearing the complex, harmonic wail of a classic naturally aspirated V12. The exhaust valve modulates gas flow based on how many units are active, managing both the catalyst temperature and the acoustic profile.[2][6]

There is still uncertainty about when, or if, this exact architecture will reach a production assembly line. Automakers frequently patent wild concepts that never see the light of day. However, the sheer detail of this filing—down to the interconnected lubrication circuits and the specific Atkinson cycle combustion methods—suggests this is far more than a theoretical exercise.[1]

If realized, this technology fundamentally changes the supercar market. For collectors, it creates a new category of vehicle: the digital-analog hybrid. It preserves the sensory drama of internal combustion while delivering the instant torque and emissions compliance of an EV. For the broader automotive industry, it proves that the transition to electrification does not have to mean the death of mechanical soul.
