The Lexus LS 600h, the full hybrid Lexus flagship, gains a range of technological and styling improvements for the 2010 model year, changes that have been unveiled for the first time at the 2009 Frankfurt Motor Show.
With redesigned seating, updated equipment, a new ECO driving mode and new brakes, the Lexus LS 600h and the long wheelbase Lexus LS 600h L achieve advances in comfort and driving dynamics.
Lexus Hybrid Drive system
The full hybrid Lexus Hybrid Drive system that powers the Lexus LS 600h has a new ECO mode, which modifies the throttle action and performance of the air conditioning system to support fuel-efficient driving.
The relationship between movement of the accelerator pedal and system output is automatically controlled, reducing response to aggressive inputs to improve fuel economy and promote smoother driving. The load on the engine is also reduced under acceleration, which also helps improve fuel efficiency.
When the outside temperature is 20°C or higher, the air conditioning system automatically selects its air recirculation mode to reduce power consumption. The blower airflow is reduced when set to "high" and operation of the supplementary electrical heating system (the PTcompact heater) is stopped, further cutting the amount of power used. Also, the system will not signal for an increase in engine speed to boost power when the vehicle is at idle.
Repackaging of the full hybrid system's battery into two sections of six and 14 modules has reduced its overall size and freed up more luggage space in the boot.
