Comparing the 2025 Lexus TX and 2025 Lexus GX: Engine, Capacity, Interior Space

The 2025 Lexus TX and GX represent fundamentally different approaches to three-row luxury SUVs. While the TX prioritizes modern efficiency and passenger comfort through unibody construction, the GX delivers traditional body-on-frame durability with genuine off-road capability. Understanding their powertrain options, interior dimensions, and cargo flexibility helps determine which Lexus SUV aligns with your driving needs.

These distinct philosophies shape every aspect of design and engineering. The TX maximizes interior volume and fuel efficiency for daily family use, while the GX's robust frame provides the foundation for serious towing and trail adventures.

Engine Performance and Efficiency

The powertrain options reveal each vehicle's core purpose:

The GX 550's twin-turbocharged V6 generates substantial torque for towing and off-road challenges. Full-time four-wheel drive comes standard, enhanced by a Torsen limited-slip differential that maintains traction across varying terrain. This single powertrain option simplifies the GX lineup while ensuring consistent capability.

The TX offers two distinct powertrains. The TX 350's turbocharged four-cylinder balances performance with efficiency, achieving 10.3L/100km while producing adequate power for most driving situations. The TX 500h hybrid elevates both performance and efficiency, delivering 366 total system horsepower while achieving an impressive 8.6L/100km—making it the efficiency leader among full-size luxury SUVs.

Interior Space and Passenger Comfort

Interior measurements highlight the TX's passenger-first engineering:

The TX's architecture creates notably more passenger space. Third-row legroom stands out with 851mm—41mm more than the GX provides. This difference transforms the TX's third row from occasional use to genuinely comfortable adult seating. Second-row passengers also benefit from 70mm of additional legroom, enhancing comfort during extended trips.

Shoulder room measurements further demonstrate the TX's spacious cabin. The TX provides 1,524mm front, 1,501mm second-row, and 1,460mm third-row shoulder space. The GX offers comparable front-row width but falls behind in rear passenger areas, affecting three-across seating comfort.

Cargo Capacity and Versatility

Storage capabilities vary dramatically between models:

Cargo volume strongly favors the TX. Behind the third row, the TX offers 572 litres—nearly double the GX's 292 litres. This advantage continues with seats folded, where the TX provides 487 more litres than the GX. Maximum cargo capacity reaches 2,747 litres in the TX versus 2,178 litres in the GX.

However, towing reverses these advantages. The GX's 4,111 kg rating doubles the TX's 2,268 kg capacity, positioning the GX as the clear choice for substantial trailers, boats, or recreational equipment. Body-on-frame construction and the powerful V6 engine enable this impressive capability.

Practical features enhance both vehicles' utility: 

• GX: Standard 120V/400W cargo outlet, available cooling box on Overtrail models 
• TX 500h: Optional 1,500W inverter on select trims for powering larger devices
• Both models: Multiple USB ports throughout cabin for device charging

Choosing Your Ideal Lexus SUV

Your driving priorities determine the optimal choice. The TX excels for families prioritizing passenger comfort and fuel efficiency. Its superior third-row space accommodates adults comfortably, while the hybrid option delivers exceptional efficiency for daily commuting. Choose the TX when interior refinement and modern technology take precedence over maximum capability.

The GX serves buyers requiring serious towing capacity or off-road confidence. Its traditional construction handles demanding tasks while specialized features like crawl control and multi-terrain select conquer challenging terrain. Adventure enthusiasts and those with heavy-duty requirements will appreciate the GX's robust engineering.
