And we're LIVE at Show in Detroit, MI.

If you're here this week, come find us at Booth #34016.

XPONENTIAL brings together the global leaders in autonomous systems and robotics and it's exactly the community we build for. The autonomous systems world has a fundamental problem: platforms need more power in a smaller package, especially for UAS applications. That's what our X-Engine was designed to solve.

Our rotary engine platform, built on the patented High Efficiency Hybrid Cycle™ (HEHC), can be up 5–10x smaller and lighter than an equivalent diesel piston engine. But ours runs on diesel, jet fuel, biofuels, and more.

American-made power, built for the next generation of unmanned systems.

Right now, we're advancing an eVTOL prototype for a UAS field-demonstration program under our $35M U.S. Air Force STRATFI contract, and progressing Army SBIR work on hybrid-electric propulsion systems. The potential applications span UAS propulsion, portable power generation, and vehicle APUs.

Detroit, let's talk engines. 🔩

We're excited to be featured in the The Wall Street Journal for our novel take on the rotary engine and it's numerous hybrid-electric system applications.

Just another example that the future isn't combustion vs electric, it's combustion enabling electric where batteries can't reach.

The rotary engine makes a comeback for cars and drones as gasoline gains popularity as a complement to electric motors.

Our engineers see things through form concept ideation, through design and simulation, and all the way through to testing.

Here's two engineers running calibration sweeps for the XTS-210 engine we're building for the U.S. Army's Ultra-Compact Mobile Command Post program. It's part of their CATALYST SBIR initiative, designing power systems that can actually survive in the field.

There's nothing quite like seeing the prototype coming to life as we harden and stress test it on the road to deployment!

When one of the world's leading powertrain engineers says your project is "genuinely compelling," you know you're onto something extraordinary.

Powertrain International sat down with our new VP of Engineering, Vincenzo Perrone, to explore how LiquidPiston is reimagining rotary engines from first principles.

From fuel flexibility to Atkinson-cycle efficiency gains, we're solving problems the traditional Wankel couldn't.

As Vincenzo puts it: "There is virtually no scientific literature available: there is no established baseline. Every day, we write a new chapter."

110+ patents. Fuel agnosticism. Power reimagined.

We're beyond excited to welcome Vincenzo to the LiquidPiston team!
