Luxury carmaker Lexus is set to break into new sales territory with customer deliveries on target to surge beyond an unprecedented 9,000 vehicles for the year.

Official figures show Lexus sales have risen 4.9 per cent to 8,561 passenger cars and SUVs so far this year - its highest total ever to the end of November.

These results have propelled Lexus to within just 130 vehicles - or less than one week's sales - of the record total of 8,691 sales achieved by the brand in 2015.

Lexus has benefited from a nationwide trend towards SUV purchases.

Demand for the Lexus NX and RX Lines has increased by 15 per cent each this year, while its flagship LX Line has experienced growth of 50 per cent.

In just its second full year on the market, the NX Line has become the second Lexus SUV to surpass 3,000 sales in a year.

Lexus passenger-car sales are also contributing to the brand's success. The company's most accessible hybrid passenger car, the premium CT 200h, has gained almost 24.7 per cent this year, achieving its best result since 2012. The GS Line has also accelerated, with sales increasing by more than 60 per cent.

Lexus Australia chief executive Peter McGregor said the brand had been able to achieve significant sales success through the strength of its product and dedication to customer service.

"Lexus is proud to be achieving record-breaking sales, which are a direct reflection of innovation and excellence - both in our vehicles and for the Lexus ownership experience," Mr McGregor said.

"The arrival of engaging new product lines, including the recently updated IS Line, will help Lexus maintain its momentum into next year."
