A detailed look at how two of Australia's most popular SUVs compare on price, running costs, safety, and everyday livability.
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Price Breakdown
The Hyundai IONIQ 9 starts from $119,750 before on-road costs, while the Lexus GX opens at $119,950. That makes the Hyundai IONIQ 9 the more affordable entry point by $200.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $131,725 and $131,945 respectively.
The Hyundai IONIQ 9 qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Lexus GX, as a petrol model, does not qualify.

The Hyundai IONIQ 9 stands out with panoramic roof, V2L, Bose audio and ambient lighting that you will not find on the Lexus GX. Which feature set matters more depends on your daily routine and priorities.
Drivetrain

The Lexus GX responds with a Petrol making 262kW and 650Nm, paired to a 10-speed auto driving the rear wheels.
The Hyundai IONIQ 9 has the clear power advantage at 314kW vs 262kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
