Innovation
Innovative technology stretches a gallon of gas further than ever before. The revolutionary Lexus hybrid system combines an advanced internal combustion engine and electric motor technology, all managed by intelligent electronic control systems. This helps increase fuel economy along with reducing CO2 emissions. Increased performance, less gas: Lexus hybrid technology isn't just an important moment in the history of luxury vehicles. It's the beginning of a whole new history altogether.

Regenerative Braking
Regenerative braking is an advanced feature that allows the electric motor to act as a generator when braking. It captures kinetic energy that normally would be lost during the vehicle's deceleration, and converts it into electric energy. This energy recharges the battery, further increasing the hybrid system's efficiency. The regenerative braking system is especially effective during city driving, where repeated stopping is common.

Electronic Control Unit
Essentially the "brain" of the hybrid system, the Electronic Control Unit (ECU) manages the power flow between the generator, battery and motor. By constantly monitoring various driving conditions, the ECU allows the transmission to get optimal power and fuel consumption from the powertrain.

Planetary Gear Set
While the ECU is the "brain" of the hybrid system, the planetary gear set manages the physical interaction between the engine, electric motor and generator. The Planetary Gear is ingenious in its ability to seamlessly harness and transmit power from the high-speed electric motor, enabling a more compact, as well as more powerful motor. Because of this leap forward in efficiency, the gear should enjoy much longer life, and result in fewer frictional losses and quieter driving.

Continuously Variable Transmission
Performance is further enhanced by the amazing Continuously Variable Transmission (CVT). Unlike typical automatic transmissions which have a fixed number of gear combinations, the hybrid's CVT allows for virtually unlimited combinations, maximizing the powertrain's efficiency and allowing the driver to enjoy a smoother, jolt-free acceleration that can't be experienced with conventional transmissions; and yet the CVT does not require more maintenance.
