Land Rover Range Rover Sport vs Lexus GX

The Sport opens at $183,751 driveaway against $130,715 for the GX Luxury, both on August 2026 pricing. Where the Lexus tops out at $144,054, the Sport's twelve-derivative ladder climbs to $378,001. The premium buys the tested five-star file, the air suspension and the engine range. It does not buy seats: every Sport carries five, while the GX Luxury and Sports Luxury carry up to seven. Nor does it buy standard low range at entry, which the Lexus fits to every grade. The gap is honest money for polish and provenance, not for capability hardware.

The Lexus, and it is the side costing $53,036 less at entry on August 2026 pricing. Two of its three grades, the Luxury and Sports Luxury, carry up to seven seats with a third row rated for occasional use; the off-road-focused Overtrail deletes it and seats five. Every Range Rover Sport is a five-seater; Land Rover reserves the third row for other models in its range. So a family that needs even part-time seven-seat capability has one side of this page to shop.

The Sport is the one with a certificate. Its five-star ANCAP rating, from 2022 testing, covers the range with sub-scores of 85 per cent adult occupant, 86 per cent child occupant, 84 per cent safety assist and 69 per cent for vulnerable road users. The GX carries no ANCAP rating at all: it has never been tested, and it does not inherit the five stars of the related Toyota Prado. That is an absence of evidence rather than evidence of weakness, and the Lexus fits nine airbags and the full assist suite standard. But a buyer who wants the tested file has exactly one option here, and it is the Land Rover.

They split on philosophy. The GX builds the hardware in: a low-range transfer case and locking centre differential on every grade, full-time four-wheel drive and a fixed 220mm of clearance, with the Overtrail adding all-terrain rubber as the dedicated bush grade. The Sport meters its hardware by trim, with the twin-speed transfer box optional on the entry Dynamic SE and absent on the SV family, but its air suspension lifts it to 283mm of clearance and 900mm of wading when raised, and its approach and departure angles of 33 and 29.8 degrees clear the GX's 26 and 22. Standard capability belongs to the Lexus. The Sport claims the higher peak, but only with the twin-speed box and the suspension raised.

Both ranges headline the class-standard 3,500kg braked, and both make you check the fine print. In the GX range the Luxury and Overtrail carry the full 3,500kg rating while the Sports Luxury drops to 3,130kg on its larger wheels. In the Sport range the diesels and petrols tow 3,500kg, but the P460e plug-in hybrid gives up 500kg. Unbraked is 750kg everywhere. The Sport publishes a 350kg tow-ball limit; no comparable GX figure has cleared our verification yet. Pick the grade for the van first, then the badge.

The running costs lean the Land Rover's way. The Sport's core diesels claim 7.3L/100km, where the GX's twin-turbo petrol V6 claims 12.3L/100km with no hybrid option for Australia, a position Lexus has stated openly. Servicing widens it: the GX costs $695 a visit on a six-month, 10,000km cadence, about $6,950 over five years on August 2026 pricing, while our data holds no published Sport servicing total for a direct comparison. Warranty is a tie at five years with no kilometre cap on both; roadside assistance runs five years with the Land Rover and three with the Lexus.

At the point most buyers enter, the Lexus. Its 260kW and 650Nm twin-turbo V6 outguns the Sport's core D300 and D350 diesels, which peak at 258kW and 700Nm, and the entry D300 claims a brisk 6.4 seconds to 100km/h regardless. The Sport's answer is range: a 338kW plug-in hybrid, the 390kW P530 and the 467kW SV family sit above anything Lexus offers the GX in Australia. At the entry money most buyers spend, the GX wins on power. Everything above is the Sport's alone, because the Lexus range simply stops.

Both things are true. Australian reviewers frame the 260kW GX against the Land Rover Defender, the other boxy luxury off-roader with genuine hardware, and that comparison lives on its own page here. But buyer behaviour adds this pairing: the GX and the Range Rover Sport are cross-shopped as the two ways to spend serious luxury-SUV money on something that can actually leave the bitumen. The Defender contests the GX on hardware and image. The Sport meets it on refinement and badge reach. If your shortlist has the GX on it, the honest move is reading both matchups before signing anything.

Run the brief, not the badge. If it includes a third row, standard low range or keeping $53,036 on August 2026 driveaway pricing, the GX Luxury is the answer and the decision is short. If it reads refinement first, the Sport's air-sprung ride and tested five-star file justify the climb, and the D350 grades make the strongest case with 700Nm and 7.3L/100km claimed. The GX asks you to accept the missing certificate, the thirstier V6 and $6,950 of five-year servicing. With the Sport, the concessions are the money and the seat count. Both are genuine off-roaders wearing luxury clothes, which is precisely why this pairing keeps showing up in the same driveway deliberations.
