2026 Lexus TX 350 vs. 500h vs. 550h+
Battle of the Powertrains
Selecting the right 2026 Lexus TX is not merely a choice of trim levels; it is a choice between three distinct engineering philosophies. Lexus has tailored the TX lineup to offer three unique driving characters: the turbocharged utility of the TX 350, the performance-hybrid agility of the TX 500h, and the electrified efficiency of the TX 550h+ Plug-in Hybrid Electric Vehicle (PHEV).
For Riverside drivers, the difference lies in how you plan to use the vehicle. Whether navigating the daily commute on the 91 Freeway or towing a boat to Lake Perris, understanding the mechanical nuances of these three powertrains is essential to making the right investment.
The Contenders at a Glance
Before dissecting the engineering, here is how the three powertrains compare on paper.

TX 350: The Turbocharged Foundation
Best For: Maximum value and traditional towing utility.
The TX 350 is the only model in the lineup available with Front-Wheel Drive (FWD) or a traditional All-Wheel Drive (AWD) system. Under the hood, it utilizes a 2.4L Turbocharged Inline-4 engine featuring a center injection system for stable combustion.
Crucially, this engine is paired with an 8-speed Direct Shift automatic transmission. Unlike a CVT, this transmission uses a wide gear range and close ratios to provide the rhythmic, stepped shifting feel that many traditionalist drivers prefer. It delivers 317 lb-ft of torque low in the rev range (1,700-3,600 rpm), making it highly capable for merging onto highways or pulling a 5,000-lb trailer.
TX 500h: F SPORT Performance Hybrid
Best For: Drivers who want sport sedan engagement in a three-row SUV.
The TX 500h is available exclusively in F SPORT Performance grades, signaling its intent. It swaps the 8-speed transmission for a high-torque 6-speed automatic integrated with a parallel hybrid system.
The engineering headline here is DIRECT4 All-Wheel Drive. This system uses a high-output eAxle (electric motor) on the rear wheels to adjust front-to-rear torque distribution instantly, from 100:0 to 20:80. When entering a corner, it biases the front for stability; on exit, it shifts power to the rear for exhilarating acceleration. This is paired with Dynamic Rear Steering (DRS), which turns the rear wheels slightly to tighten the turning radius at low speeds and enhance stability at high speeds.
TX 550h+: The Plug-in Hybrid Flagship
Best For: The daily commuter who wants zero-emission city driving.
The TX 550h+ is the most powerful and efficient model in the lineup. It combines a smooth 3.5L V6 engine with high-output electric motors and an 18.1-kWh lithium-ion battery pack mounted beneath the floor.
This setup generates a massive 404 total horsepower, propelling the three-row SUV from 0-60 mph in just 5.9 seconds. However, the real advantage is the 33-mile all-electric range. For many Riverside residents, this covers the daily round trip to work or school without burning a drop of gasoline. Once the battery is depleted, it functions as a highly efficient hybrid, delivering an estimated 29 MPG combined.
Choose the TX 350 if:
You want the lowest cost of entry and prefer the feel of a traditional 8-speed automatic transmission over a hybrid system.
Choose the TX 500h if:
You drive spiritedly. The combination of DIRECT4 and Rear Steering makes this large SUV feel surprisingly nimble on winding roads like Reche Canyon.
Choose the TX 550h+ if:
You have access to charging at home. The ability to drive 33 miles on electric power alone provides the quiet luxury of an EV for daily errands, with the V6 engine ready for long-distance road trips.
