The "Impossible" 106 MPG Engine That Broke Physics: Why Did Detroit Destroy It?

The "Impossible" 106 MPG Engine That Broke Physics: Why Did Detroit Destroy It? Why was the most fuel-efficient family powertrain in American history quietly pulled from production just as the rest of the world began trying to copy it? For the past decade, drivers across America have been told that the internal combustion engine is headed straight for extinction. But while public attention was focused entirely on battery-electric range anxiety and charging grid debates, American engineers and physicists were running secret military tests, breaking 100-year-old thermodynamic limits, and radically redesigning gas engines from the ground up. In this deep dive, Engine Autopsy investigates the secret renaissance of combustion technology—from valveless opposed-piston semi engines and inverted rotaries that run on vodka, to crankshaft-free linear generators and the 106 MPGe American engineering marvel that Detroit built, proved, and mysteriously killed. Are we witnessing the death of gas engines, or are range-extended powertrains (EREVs) and ultra-high-efficiency combustion systems about to dominate the next generation of American highways?
