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 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.
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.
Further development of the Lexus Hybrid Drive system has been revised to meet Euro V exhaust emissions standards, but with no change to the car's performance: the combination of the 5.0-litre V8 petrol engine and 165kW electric motor produces a maximum 439bhp and 520Nm of torque, giving nought to 62mph acceleration in 6.3 seconds. CO2 emissions are 219g/km and combined cycle fuel economy remains 30.4mpg (figures provisional prior to UK homologation).
The revised model is distinguished visually by a new four-bar grille and front bumper with redesigned air intakes and foglamps. The headlamps have a new running light design and are finished in Lexus hybrid blue, giving the car a distinctive appearance befitting its flagship status.
In the cabin the instrument binnacle has been revised to include a new full colour, TFT LCD display. A new meter design features a three-ring analogue dial with a central speedometer, a tachometer and coolant temperature gauge to the left, and a fuel gauge and hybrid system indicator to the right. A display in the centre of the speedometer can be customised to display vehicle information, turn-by-turn navigation instructions and hybrid system status.
Both front seats are equipped with new, inflator operated active headrests. Activated by a signal from the airbag ECU in the event of a rear impact, the inflator slides a piston into the headrest, unlocking a mechanism that projects the headrest forwards and upwards, reducing the risk of whiplash injury.
In common with its sister Lexus models, the Lexus LS 600h is adopting a new hard disc drive (HDD) navigation system with the 40GB capacity, giving Europe-wide coverage with traffic information data capture in each country.
The 19-speaker Mark Levinson Premium Surround Sound System fitted as standard in the Lexus LS 600h gives 7.1-channel surround sound on selected CDs and DVDs. It is now DAB ready (DAB audio will be available as a centre-fitted accessory) and provides USB and audio jack plug connection for fully controlled use of portable music players, and Bluetooth with an audio streaming function.
It also provides a new 'sound library' function, using the navigation system's HDD to transfer and store music files from CD up to 10GB capacity - the equivalent of about 2,000 music tracks.
The revised Lexus LS 600h features a new, automatic high beam system. A camera sensor in the rear view mirror detects oncoming traffic, street lamps and vehicles travelling ahead and automatically switches the headlamp high beam on and off according to driving conditions.
