The LS 600h benefits from over a decade of leadership in hybrid technology to offer breathtaking performance. Its innovative Lexus Hybrid Drive intelligently marries a precision-engineered, 5-litre direct injection V8 petrol engine with a high output electric motor to produce stunning results. With a combined power output of 445 DIN hp, acceleration reaches 0 – 100 km/h in only 6.1 seconds and is utterly seamless. Fuel consumption has been reduced considerably to 8.6 l/100 km. And CO2 emissions are just 199 g/km – far below what might be expected from a car of this class. In addition, the LS can also be switched to ECO mode – re-tuning the throttle and onboard climate control to conserve fuel and reduce emissions even further.
The ‘brain’ of the LS is an advanced Power Control Unit (PCU), which oversees the energy management of this unique, full hybrid engine. When in Electric Vehicle (EV) mode, the car produces zero CO2 or NOx emissions, will use no petrol and is almost completely silent. The PCU defaults to this mode when you first switch on the engine or are proceeding at low speed. But as you speed up, the petrol engine seamlessly kicks in and the two power sources work in harmony. At faster speeds, the powerful electric motor is used to provide a smooth and instant surge of torque when accelerating. The compact, hybrid battery never needs to be re-charged as kinetic energy is harnessed when braking or decelerating. This is then converted for storage in the battery.
The LS benefits from a permanent All Wheel Drive system that provides enhanced traction to cope with even the most demanding driving conditions. Its Hybrid Drive transmission houses an electric motor, generator power, power split planetary gear mechanism and motor-speed reduction gearing in one, lightweight compact casing, no bigger than a conventional automatic gearbox.
All in all, the LS600h is a technological achievement that could only have come from the peerless automotive ingenuity of Lexus.
