2026 Lexus UX 300h Technical Specifications
Deep Dive
The 2026 Lexus UX 300h is engineered around a high-strength global architecture platform. By utilizing aluminum for the side doors, fenders, and hood, alongside composite materials for the tailgate, Lexus has achieved a highly rigid structure with a low center of gravity. This translates to precise handling and a refined cabin experience.
Below is a detailed breakdown of the technical specifications, hybrid architecture, and interior dimensions that define the 2026 UX 300h.
Fifth-Generation Hybrid Architecture
The UX 300h is exclusively available with a hybrid powertrain. The system utilizes a compact, 60-cell lithium-ion battery. Lexus engineers strategically positioned this battery underneath the rear seat to preserve cargo capacity and optimize weight distribution.
The front electric motor generates 83 kW. On models equipped with the E-Four all-wheel-drive system, a permanent synchronous motor is added to the rear axle, providing an additional 30 kW of output. This rear motor delivers near-instantaneous drive force in low-grip scenarios.
| Performance Metric | Specification |
|---|---|
| Engine Configuration | 2.0L In-line 4-cylinder |
| Hybrid Battery | 60-cell Lithium-ion (222V Nominal Voltage) |
| Total System Output | 196 horsepower |
| Front Motor Max Torque | 151.9 lb-ft |
| Rear Motor Max Torque (AWD) | 62.0 lb-ft |
| 0 to 60 MPH Acceleration | 8.0 sec (FWD) / 7.9 sec (AWD) |
Interior Dimensions and Cargo Capacity
Despite its compact exterior footprint, the UX 300h offers a carefully packaged interior. The seating configuration accommodates five passengers. The hip-point is optimized to make entering and exiting the vehicle effortless.
- Front Headroom: 37.28 inches (Normal Roof)
- Front Legroom: 42.05 inches
- Rear Legroom: 33.13 inches
- Cargo Space (SAE): 17.2 cubic feet
Handling Riverside Terrain
The UX 300h features a minimum running ground clearance of 6.3 inches. This specification is crucial for urban environments. It provides sufficient height to clear steep driveway approaches and minor road debris while maintaining a low enough profile to reduce body roll during cornering.
The suspension setup consists of MacPherson struts in the front and a trailing arm double-wishbone configuration in the rear. This engineering allows the UX 300h to absorb the uneven pavement found on historic Victoria Avenue while remaining planted and stable during higher-speed transitions on the I-215 interchange.
