THE full hybrid LS 600h limousine from Lexus has been upgraded with more advanced technology and extra passenger comfort.

Already one of the most luxurious cars on the market, the revised range now centres on the five-seat LS 600h L long-wheelbase model equipped with a Rear Seat Relaxation Package.

Lexus has made the pack available as an option for five as well as four-seat models aimed at providing an unmatched travelling environment.

The package equips the left hand rear seat with an electrically adjustable ottoman foot and thigh rest and an adjustable massage function that can replicate techniques from Shiatsu to acupressure.

The seat is fitted with cushion airbag and, to give a clear view, the front passenger headrest can be electrically folded down, while all rear seats have an electric recline adjustment.

And there's now a more sophisticated climate control system that monitors the passengers' body temperature for more effective control of the cabin environment.

 For the four-seat version, a fixed centre console is provided with a built-in cool box, DVD and CD store and a retracting and adjustable wood inlaid tray.

The advanced headlight system is further improved with the adoption of automatic high beam operation. A sensor in the rear view mirror detects on-coming traffic, street lights and vehicles ahead and automatically switches the headlight high beam on and off as conditions require.

Also improved - by 12.5 per cent - is the performance of the LS 600h's electronically controlled brakes.

The 2010 car also gains new LCD dashboard instrumentation and improved "butterfly" design headrests, while all versions of the car now benefit from the Rear Seat Upgrade Package, which includes four-zone climate control, rear side airbags, electric sunshades on the rear doors, electrically adjustable rear seats with memory settings, lumbar massage and integrated air conditioning.

Prices are from £87,440 for the LS 600h L, though the same model with the relaxation package costs £96,645.
