In a bold move that proves the combustion engine still has life left, Porsche has filed a patent for an 18-cylinder W-shaped engine. The design is nothing short of audacious, signaling that the German automaker continues to explore the extremes of performance and innovation—even as the industry shifts toward electrification.
This newly patented engine isn’t just another concept—it’s a mechanical statement. Porsche’s engineers have envisioned a space-optimized layout capable of delivering immense power in a surprisingly compact package.
A True W-Shaped Masterpiece
Unlike previous “W” engines, such as Bugatti’s W16, which essentially combines two narrow V8 banks sharing a single crankshaft, Porsche’s design is a genuine W-configuration. The patent describes three banks of cylinders—each bank potentially featuring six, five, or even three cylinders—arranged in a true W pattern.
This setup allows Porsche to achieve an 18-cylinder engine that’s roughly as long as a straight-six, compact yet capable of monstrous output. It’s an elegant fusion of performance and practicality, reflecting Porsche’s unmatched engineering prowess.
Intelligent Airflow and Cooling Design
Porsche’s engineers focused heavily on thermal efficiency and air management. The patent outlines a clever intake and exhaust routing system:
- Exhaust gases are expelled between and underneath the cylinders.
- Air intakes sit on top, where airflow is cooler and cleaner.
This separation minimizes frictional losses and prevents heat transfer between intake and exhaust systems. In Porsche’s own translated words, this configuration ensures that “fresh air to be sucked in cannot heat up via wall heat.”
Cooler air leads to denser oxygen intake—and more power.
Turbocharged Triple Threat
As if 18 cylinders weren’t enough, Porsche’s patent suggests the engine could accommodate a turbocharger per bank—meaning up to three turbochargers in total. A triple-turbocharged W-18 engine promises a unique balance of low-end torque, top-end power, and responsiveness, all within a relatively short engine block.
If realized, this would be one of the most advanced and compact high-displacement engines ever conceived for a road car.
Will It Ever See Production?
While enthusiasts are already dreaming of an 18-cylinder supercar, Porsche might never build this engine. Automakers often file patents to protect intellectual property rather than preview production models.
However, recent trends show Porsche’s commitment to keeping combustion alive. The upcoming ultra-luxury SUV will now debut as a hybrid instead of an EV, and the next-generation 718 is confirmed to retain gas-powered options. That leaves room—at least theoretically—for a radical new internal combustion design to make its way into the lineup.
The Spirit of Innovation Lives On
Whether or not Porsche’s W-18 ever roars to life, this patent is proof that the company’s engineers remain as ambitious as ever. At a time when the industry is pivoting to electric powertrains, Porsche continues to refine and reimagine the art of combustion.
An 18-cylinder, triple-turbo, space-optimized W-engine might sound like an engineer’s fantasy—but with Porsche, even the wildest dreams have a habit of becoming reality.
