The 2025 Lexus GX is a petrol SUV with AWD and seating for 7. It belongs to the Gen 3 generation. The 550 Overtrail is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured 550 Overtrail version develops 349 hp and 649 Nm (479 lb-ft) of torque. Its listed 0-100 km/h time is 7.0 seconds, which is responsive rather than outright performance-focused. Top speed is listed at 185 km/h (115 mph). Its power output is about 27% above the peer average. Its acceleration is close to the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 11.2 L/100km. Fuel-tank capacity is 87.0 litres (23.0 US gallons). Recorded CO2 emissions are 256 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 4,955 mm (195.1 in) in length, 1,980 mm (78.0 in) in width, and 1,870 mm (73.6 in) in height, while the wheelbase measures 2,850 mm (112.2 in). Cargo capacity is listed at 521 litres (18.4 cu ft), expanding to 1,865 litres (65.9 cu ft) with the rear seats folded. The cabin is configured for 7 occupants. Listed curb weight is 2,495 kg (5,501 lb). The recorded braked towing capacity is 3,175 kg (7,000 lb). That cargo volume is about 8% below the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
The model range
The recorded line-up consists of Premium, 550 Overtrail, and Overtrail. Across the range, the specifications span 349 hp and 6.5 s to 7.0 s, while listed starting prices run from $65,975-$70,665. Drivetrain, battery or engine choice, wheels and market equipment can all change the final figures, so the version table should be used when choosing between them.
In perspective
Compared with nearby petrol SUV models from the same period, the 2025 Lexus GX is strongest on towing capacity and power, while price and cargo capacity stand out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
