Lexus has added the 'Advance' trim level to its RX450h line-up, sitting at a higher grade than the current 'Luxury'.

Advance adds a new set of styling features, including a new, deep front bumper and LED headlight units. The lights benefit from Lexus's I-AFS auto-adaptive system, moving in line with the steering to give better illumination at junctions and through bends.

The specification also includes new seven-spoke 19-inch alloy wheels and the choice of either a fixed panoramic roof or an electric sunroof.

The standard equipment list includes Smart Entry and Start; dual-zone climate control; leather upholstery; heated, eight-way adjustable front seats; heated, auto-diming and folding door mirrors, automatic windscreen wipers; and rear privacy glass.

On-board connectivity and infotainment are included in the Lexus Premium Navigation system, 12-speaker audio pack, DVD player (single disc) and DAB tuner. The system also provides a rear-view camera and Bluetooth for hands-free calls and audio streaming.

The RX 450h's full hybrid powertrain uses a 3.5-litre V6 petrol engine and a powerful electric motor, producing a maximum 295bhp, enabling nought to 62mph acceleration in less than eight seconds. Thanks to a second electric motor on the rear axle, the system can automatically deliver all-wheel drive performance when conditions require extra grip.

Lexus's update has improved fuel economy and low emissions: official combined cycle figures are 44.8mpg and 145g/km.
