Lexus will debut the all-new IS 350 and upgraded IS 250 models along with pricing at the Australian International Motor Show (AIMS) this October.

The two models will deliver all-new styling and features across the range including a new aggressive frontal treatment, new wheel and tyre package, along with new safety and comfort refinements.

IS 350 will also debut Lexus' F Sport moniker, with F Sport models featuring unique sports-tuned suspension, wheels, spoilers, unique interior and exterior features and F Sport badging.

Meanwhile all IS models equipped with high-intensity discharge (HID) headlights gain LED daytime running lights across the range.

On the environmental front, Lexus' 2.5-litre V6 petrol engine featured in the IS 250 variants now meets overseas Euro 5* emissions regulations.

Lexus chief executive Tony Cramb said AIMS was a great opportunity for Lexus to introduce IS 350."AIMS coincides with the introduction of new IS 350 and IS 250 to our dealers, so from Lexus' point of view it's fantastic timing," said Mr Cramb.

"With IS 350's combination of specification, price and power we are certain it will impress consumers.

"The refresh across the range gives IS greater visual presence and really lifts the vehicle.

"Lexus will also take the opportunity at AIMS to introduce two other models yet to be launched locally," Mr Cramb said.

*Lexus IS models comply with international Euro 5 regulations - these may differ to local legislation which is yet to be announced.
