A published patent application is a delayed window, not a product. Under the US rules an application typically surfaces about 18 months after it is filed, so reading a company's recent publications is reading where its engineers were spending time a year and a half ago — useful precisely because it predates anything the company has shipped or announced. On March 26, 2026, the published record added a Ferrari application that is worth following the cash behind, because it is not the kind of filing the marque's combustion history would predict.

US20260088737A1 claims a method for controlling the electric motors of a road vehicle whose powertrain comprises a pair of independent electric motors, each mechanically connected to a single wheel of an axle. The claimed efficiency step alternates which of the two motors is doing the work rather than splitting the load:

The method of controlling the electric motors can comprise a motors-efficiency maximisation step that provides for alternately activating only one electric motor of said pair of electric motors, causing it to temporarily deliver the entire mechanical power and/or drive torque momentarily requested to the powertrain.— Method for controlling the electric motors of a road motor vehicle, US20260088737A1

The application is classified in B60K and B60L — the electric-propulsion families — and the architecture it describes, one motor per wheel with software arbitrating torque, is a building block for an electric drivetrain rather than a tweak to an engine. Taken alone it is one filing. Read against the rest of Ferrari's recent published cluster, it stops looking like an outlier.

The cluster is mostly about heat

The clearest pattern in Ferrari's recent publications is thermal management — the problem that grows when propulsion becomes electric and a pack, an inverter and a cabin all need separate temperature control. US20260158850A1 claims a motor-vehicle conditioning circuit whose second heat exchanger uses a phase-change material that switches between solid and liquid phases to exchange latent heat with the conditioning fluid. US20260152042A1 describes a multi-circuit motor-vehicle cooling and cabin-air system, with a cooling-fluid circuit, a passenger-compartment air circuit and a heat-transfer-fluid circuit thermally coupled together. Two thermal-system filings in the same recent window, both at the vehicle level, indicate development effort aimed at moving and storing heat rather than at the combustion process that traditionally generated it.

A third filing widens the picture toward energy capture. US20260155775A1 claims a road vehicle with a roll-up photovoltaic panel that moves between a retracted position inside a housing on the outer body and an extracted position extending along the passenger compartment or body — an on-body solar concept classified in the H02S photovoltaic and B60L electric-propulsion families. Solar-on-body is a niche idea, but its presence in the cluster is consistent with a research program thinking about vehicle-level electrical energy, not just the engine bay.

What the filings point to, and what they don't

Set the records side by side — per-wheel electric motors with torque arbitration, two vehicle-level thermal-management circuits, an on-body solar panel — and the cluster points to R&D directed at electrified propulsion and the heat and energy management that come with it. For a company whose brand and revenue have rested on internal combustion, that is a meaningful direction to read in the filings, and it is the kind of signal that an ~18-month-delayed publication record is well suited to surface. The aerodynamic and structural filings in the same recent window — an aerodynamic vent duct through a frame absorption beam (US20260159168A1) and a door-frame longitudinal beam defining an aerodynamic conduit (US20260159182A1) — show the body and aero work continuing in parallel, so the electrification filings are an addition to the program, not a wholesale pivot the record can confirm.

The limits matter. An application is a disclosure, not a granted claim and not a shipping system; the per-wheel-motor method may never reach a road car, and the company's published filings are only the subset that has surfaced under the 18-month rule. What the record supports is narrow and factual: in its recent publications, Ferrari has been filing on electric-drivetrain control and on the thermal and energy systems that surround it. For a desk that reads applications as a forward indicator of where development capital has been pointed, that cluster is the signal — not a forecast of the next model, but evidence of where the engineering hours went.
