2026 Lexus TX Specs
The three-row luxury SUV segment is defined by a single, critical metric: usable space. For Riverside families, a vehicle's exterior footprint must be manageable for parking at the Victoria Gardens or Galleria at Tyler, while the interior volume must accommodate adults comfortably in all positions.
The 2026 Lexus TX is engineered specifically to solve this geometric challenge. Built on the rigid Global Architecture-K (GA-K) platform, the TX optimizes its 116.1-inch wheelbase to deliver class-leading third-row livability without the unwieldy bulk of a truck-based SUV. This technical breakdown analyzes the precise dimensions, cargo capacities, and physical specifications of the 2026 model.
Exterior Dimensions & Footprint
The 2026 TX measures 203.1 inches in length (203.5 inches for F SPORT grades), placing it squarely in the "Goldilocks" zone, significantly larger than the RX for superior utility, yet more agile than the body-on-frame LX 600.
Crucially for Southern California drivers, the 78.3-inch width ensures stability on the I-215 while remaining narrow enough for standard garage bays. The 116.1-inch wheelbase pushes the wheels to the corners, maximizing the interior floor plan and reducing overhangs for a composed driving posture.
| Dimension | Specification |
|---|---|
| Overall Length | 203.1 in (Standard) / 203.5 in (F SPORT) |
| Overall Width | 78.3 in |
| Overall Height | 70.1 in |
| Wheelbase | 116.1 in |
| Track Width (Front/Rear) | 67.4 in / 67.8 in |
| Ground Clearance | 7.9 in |
Interior Volume: The Third-Row Advantage
Lexus engineers prioritized the "third-row experience" during the TX’s development. Unlike competitors where the rear seats are strictly for children, the TX offers 33.5 inches of third-row legroom. This creates a viable seating position for adults, aided by a slide-assist mechanism that tilts the second-row seats forward for effortless ingress and egress.
The cabin utilizes a stadium-style seating arrangement to ensure visibility and airflow for all passengers, supported by dedicated third-row climate vents.
| Row | Headroom | Legroom | Shoulder Room |
|---|---|---|---|
| Front Row | 41.5 in | 41.6 in | 60.0 in |
| Second Row | 40.2 in | 39.5 in | 59.0 in |
| Third Row | 37.2 in | 33.5 in | 57.4 in |
Cargo Capacity & Utility
Utility is the primary reason for choosing a TX over an RX. The vehicle offers 20.2 cubic feet of cargo space behind the third row, enough to accommodate seven carry-on suitcases without folding a single seat. This is a critical engineering achievement, ensuring that full passenger capacity does not negate cargo capability.
For maximum utility, folding the second and third rows reveals a cavernous 97.0 cubic feet of volume with a flat load floor, ideal for hauling larger items.
| Configuration | Volume (SAE) |
|---|---|
| Behind 3rd Row | 20.2 cu. ft. |
| Behind 2nd Row | 57.4 cu. ft. |
| Behind 1st Row (Max) | 97.0 cu. ft. |
Performance Specifications
While dimensions define the space, the powertrain defines how that mass moves. The TX 350 employs a high-torque turbo engine designed to move the vehicle's 4,575-lb curb weight with authority, utilizing an 8-speed transmission to keep the engine in its optimal power band.
| Key Technical Specs (TX 350 AWD) | Value |
|---|---|
| Curb Weight | 4,575 lbs |
| Fuel Tank Capacity | 17.8 Gallons |
| Towing Capacity | 5,000 lbs |
| Turning Circle | 38.0 ft |
Whether you are evaluating the TX for its garage fitment or its ability to haul the team to a tournament, the specs confirm that this SUV is designed for real-world utility.
