RXh Performance

The 2013 RX 450h features a 3.5-liter V6 Atkinson-cycle engine that works differently than conventional engines to convert more of the energy generated during combustion into mechanical energy. It also features a hybrid battery that is lightweight and remarkably compact. As a result of these advancements, the RX 450h produces a combined 295 horsepower [1], provides instantaneous torque and features a class-leading 30 mpg fuel-economy rating [2].

The RX 450h includes innovative systems that contribute to efficiency and a fuel-economy rating that surpasses that of an average four-cylinder midsize sedan. One of these systems is an Exhaust Heat-Recovery system that captures a portion of the exhaust gasses generated during startup and uses them to help warm the gasoline engine. On cold days, this can significantly reduce the time it takes for the RX 450h to reach a point where it can shut off the gasoline engine and function on battery power alone, by up to 15 minutes in some cases.
