The 3.5-liter V6 Atkinson-cycle engine is able to convert more of the energy generated during combustion into mechanical energy than conventional engines. This innovative system contributes to low emissions and enhanced fuel efficiency.

The RX Hybrid captures, cools and reuses exhaust gas, reducing emissions and providing best-in-class fuel economy. A portion of these gasses is used to warm up the engine, significantly shortening the time it takes the RX to reach a temperature at which it can function on battery power alone.

The RX Hybrid is the first hybrid vehicle to feature Intelligent Shift Control, a system that can estimate whether you are traveling uphill or downhill and automatically provide the optimal engine response. Or you can manually shift for greater responsiveness and maneuverability.
