INFINITI QX80 Vs. Lexus GX: Here's How They Compare
An INFINITI QX80 vs. Lexus GX comparison is perhaps the most comprehensive way to determine which type of luxury SUV is for you. While the Lexus GX offers enticing features, the INFINITI QX80 has the edge in engine performance, size, standard safety options, and available amenities. At West Houston INFINITI, we want to ensure your garage is fitted with only the best option for your family, so let's explore how the INFINITI QX80 leaves its lasting impression.
INFINITI QX80 at a Glance
- Stronger, more fuel-efficient V-6 engine, creating 450 horsepower
- Elegant and refined exterior with a sturdy throughline
- More spacious interior, with up to 97.1 cubic feet of cargo space and 43.8 inches of front-row legroom
- An absolutely enchanting feature lineup, such as the dual 14.3-inch infotainment displays and standard Surround View Monitor
Lexus GX at a Glance
- A strong V-6 engine, but it only creates 349 horsepower

The new INFINITI QX80 takes on the competition with ease, thanks to a carefully crafted 3.5-liter twin-turbocharged V-6 engine. Providing more horsepower and torque than its competitor, the INFINITI SUV is also more fuel-efficient than the Lexus GX when considering baseline configurations. Plus, while the Lexus GX has a higher maximum towing capacity, several of its trims (including the Luxury level) have significantly lower capability than the INFINITI QX80, which can always handle 8,500 pounds.3
INFINITI QX80 vs. Lexus GX Design
How about the bodies these engines are stored inside of? The Lexus GX boats a rather simple design, with a blocky, boxy appearance that seems durable but appliance-like. Its plain body style is far from unwanted, but a straightforward model like the Lexus GX isn't guaranteed to turn heads.
The INFINITI QX80 is another story. Slight curves accentuate the INFINITI model's exterior, creating an aerodynamic shape that complements the more expressive grille and headlights. Durability is key, but unlike the Lexus GX, the INFINITI QX80 adds more prestige through exterior elements.
INFINITI QX80 vs. Lexus GX Dimensions
| INFINITI QX80 | Lexus GX | |
|---|---|---|
| Seating Capacity | 7-8 | 5-7 |
| Length | 211.2 in | 197.1 in |
| Width | 83.3 in | 83.2 in |
| Height | 76.6 - 78 in | 75.4 - 77.2 in |
| Wheelbase | 121.1 in | 112.2 in |
| Legroom (1st / 2nd / 3rd) | 43.8 / 39.2 / 32.9 in | 41.2 / 36.7 / 37.9 in |
| Cargo Space (Trunk / Max) | 20.4 / 97.1 cu ft | 10.3 / 76.9 cu ft |
Compare INFINITI QX80 and Lexus GX size, and you'll quickly see who comes out on top. The Lexus GX scores a win with third-row legroom, but the INFINITI QX80 easily conquers the conversation with more first- and second-row legroom. Enjoy more trunk and overall cargo space in the INFINITI QX80, as well as an eight-seat configuration – absent from the Lexus GX.
Lexus GX vs. INFINITI QX80 Interior
The final stop of our 2026 INFINITI QX80 vs. 2026 Lexus GX comparison looks beyond numbers to investigate the cabins of these prestigious models.
Look first at how the INFINITI QX80 prioritizes your comfort. A 14-speaker Klipsch® sound system creates premium ambiance and is easily adjusted via a pair of 14.3-inch infotainment touchscreens standard on all INFINITI QX80 models. A dual-occupant memory system lets your family enjoy rides without having to remember seat adjustments. Your second-row seats will be heated across all levels, and unbelievable comforts, such as Blind Spot Intervention and a 3D Around View Monitor, will support your safety.
Available features across the four INFINITI QX80 trims go even further to embolden your experience: a Head-Up Display, for example, can be found standard at the LUXE level, a 24-speaker Klipsch® sound system is standard on the SPORT, and the AUTOGRAPH brings in incredible comforts such as an open-pore ash wood trim with metal inlays.
When it comes to the Lexus GX model, it's also considered a luxury SUV, but it lacks notable features in its standard and available equipment, making it seem much less comprehensive than the INFINITI equivalent. Take, for example, the sound: the Lexus GX comes standard with a 10-speaker sound system and upgrades to a 21-speaker system with its Luxury trim – the most expensive member of its lineup.
A Panoramic View Monitor only becomes standard on the second-level Premium+ trim. For screen space, the Lexus GX does have a 14-inch central touchscreen, but only a single one. Heated second-row seats are also only standard on the Premium+ trim. The Lexus GX does have more flexible seats with 10-way adjustable seating, but even then, the INFINITI QX80 offers early access to massaging seats.
Both SUVs in our INFINITI QX80 vs. Lexus GX guide have advantages, but the INFINITI QX80 consistently outpaces the Lexus model for luxury-end features.
