Getting straight out of the RX and into the MX is a reminder of how safe, comfortable and flabby modern cars are. The MX-30 ...

EV advocates argue efficiency closes the gap, but **energy density dictates engineering constraints.** An ICE vehicle’s range ...

The traditional Wankel is limited to 12:1, the liquid piston x-engine is not. That’s why they can run diesel, like in their XTS-210 compression ignition engine. Still, it’s not perfect.

I have already written about LiquidPiston and its XTS-210, but Avadi's idea is even more striking: it is a reciprocating engine that works as a rotary. Imagine an ICE with a single piston.

Rotary engines gained niche appeal and status with the Mazda RX-7 sports car, first launched in 1978. Mazda continued to prove the true potential of rotary engines by winning the Le Mans 24-Hour race ...

All-new type of gas engine offers incredible power-to-weight U.S. firm Avadi – using a Quebec inventor's design – has developed a sort of "rotary piston" ICE that could revolutionize small engines ...

Pistonless rotary engines are the engine family to which the Wankel engine belongs. These engines do not use reciprocating pistons that travel back and forth within a cylinder.
