Lexus Hybrid Drive
BENEFITS
A Powerful Statement
Lexus Hybrid Drive is an advanced gas-electric hybrid system that delivers significant environmental benefits without sacrificing power or performance. In fact, Lexus Hybrid Drive produces more horsepower than a standalone gasoline engine of equal size.
Three Operating Modes
Depending on power requirements, Lexus Hybrid Drive operates in three modes - electric motor only, engine only, or engine and motor combined. Whether working alone or in conjunction with the engine, the powerful motor(s) minimize engine use to significantly reduce harmful emissions and increase fuel efficiency.
Responsive Performance
Lexus hybrids deliver an exceptionally quiet ride and smooth, responsive acceleration. The Lexus Hybrid Drive system switches so seamlessly between operating modes that changes during acceleration or deceleration are virtually undetectable.
Fuel Efficiency
Lexus Hybrid Drive vehicles are significantly more efficient than their non-hybrid counterparts. While fuel consumption is lower for both city and highway driving, city driving requires less fuel because the electric motors are often used exclusively at low speeds.
Lower Emissions
Lexus Hybrid Drive vehicles offer significantly lower emissions than non-hybrids powered exclusively by comparable gasoline engines. Our ever-improving hybrid technology delivers reductions in both airborne pollutants and greenhouse gases.
HOW IT WORKS
Starting and Take-off
- Only the electric motors are used to initiate start-up and driving at low speeds.
- As the vehicle moves off, power is sent from the battery to the electronic control unit.
- The electronic control unit sends power to the front and rear electric motors.
Cruising
- At cruising speeds, the front wheels are driven by the engine and the motors.
- A power split device splits engine power between the wheels and the electric generator. The power distribution is controlled for maximum efficiency.
- The generator sends power to the front motors, and when necessary, recharges the battery using surplus power.
Accelerating
- The engine provides power as it would when cruising, but receives additional power from the front and rear motors.
- Engine power is also directed to the generator, which is able to redirect surplus power to electronic control unit.
Regenerative Braking and Battery Power
- Kinetic energy produced during braking is captured and sent to the electric motors.
- The kinetic energy is sent as electrical energy from both motors to the electronic control unit.
- Electric energy is then returned to the battery from the electronic control unit.
