Key Points:
- With an estimated 37 miles of electric-only driving, the RX 450h+ is practical for daily commutes without gas, but it’s price jump above the RX hybrid is hard to justify.
- The RX’s strengths include ride comfort, refinement, quietness, and efficiency.
- The plug-in system works does what it promises, making it an easy transition for buyers not ready to go fully electric.
To plug in or not to plug in, that is the question
The RX has been the brand’s best-selling model for decades. There are now gas, HEV, and PHEV versions, the latter two separated by nearly $20,000. That’s a lot of moolah just to get electric-only driving capability. The 2026 Lexus RX 450h+ might be a hard sell, as a result. Sales figures reveal that the RX hybrid outsells the PHEV about tenfold. The fact that the RX 450h+’s powertrain is the same one found in the Lexus NX PHEV and the former Toyota RAV4 Prime (both with more electric range than the RX 450h+) makes the astronomical price even more of a head-scratcher.

As the plug-in hybrid version of the RX lineup, the 450h+ is a special flavor that caters to the needs of very particular customers. They want all luxury, style, and amenities of the Lexus RX, but they want to save on gas (and trips to the pump), all the while paying through the nose for this trim. You get high style, sure, but you can still get that with the regular hybrid version.
My test vehicle had a base price of $71,860. Standard feature highlights included all-wheel drive, 21-inch aluminum alloy wheels, triple-beam LED headlights, power-folding and heated outside mirrors, Semi-aninline leather trimmed heated and ventilated power front and rear outboard seats, wood and leather-trimmed heated steering wheel, multi-zone climate control, 14-inch touchscreen display, head-up display, thematic ambient illumination, panoramic glass roof, and Wireless Apple CarPlay. Options included a Panoramic View Monitor, Traffic Jam Assist, a Mark Levinson premium audio system, Advanced Park with Remote Park, power liftgate with kick sensor, and a digital review mirror. The total price, including $1,450 destination fee, came to $76,145.
Exterior and Interior Styling – 9/10

The RX is now in its fifth generation, having been fully redesigned for the 2023 model year. It’s easily the most refined design the model has ever seen. The body is muscular but elegant, complex but cohesive. The frameless grille is now handsomely integrated into the front fascia. Those diamond shapes look like they’re floating because they’re connected to thin, black vertical pieces that vanish into the dark background. Arrow-shaped DRLS are integrated into the headlight clusters.

The doors are deeply sculpted, and the fender trim has prominent creases. The multi-spoke 21-inch wheels fill the wells properly. The most noticeable design element is the floating roof, and it’s perfectly executed here with a long, sweeping line that extends from the A-pillar to the D-pillar. The design elegance continues with the full-width wraparound tailights that look like wings. The liftgate is simple, but it still manages to be thematically consistent with the front end’s converging lines.

The RX 450h+ Luxury’s cabin is awash in beautiful surfaces and textures. Every color choice comes in Semi-anline leather with suede trim, and the look is particularly stunning in the ivory-like Macadamia color. Scalloped suede door trim and the matching fabric speaker covers look and feel sumptuous. The coloring mates nicely with the matte Ash Bamboo trim that shows up on the dash, center console, and steering wheel.

Everything in the RX 450h+ Luxury’s cabin looks and feels top-tier. Clean lines, premium materialls, artistic surfaces, and properly integrated screens give it an interior that’s commensurate with the price. It’s the brand’s best cabin, now that the beautiful LC 500 coupe is no more.
Driving Experience – 8/10
Amos Kwon
The RX 450h+ is pure Lexus when it comes to time behind the wheel. It’s quick but not sporty, smooth but not powerful. The RX 450h+ pairs a 2.5-liter four-cylinder engine with three electric motors juiced by a 18.1-kWh battery pack. All-wheel drive is standard, and the rear wheels are driven by just electric power. Combined system output lands at 304 horsepower, which is more than adequate for a vehicle focused on daily usability rather than outright speed. While that’s more than the RX 350 Hybrid’s 246 horsepower, it falls well short of the RX 500h’s 366 horsepower.

Acceleration is smooth but not authoritative. That said, 0-60 mph happens in just under six seconds. It just doesn’t feel that quick, and it announces the effort with CVT droning and a loud four-banger. This is not a sporty powertrain, but it’s never harsh or jerky. The CVT prioritizes efficiency and smoothness over engagement. Drivers expecting crisp gear changes will not find them here, but those who value a relaxed, linear feel will appreciate how unobtrusive the drivetrain remains in normal use. As expected, there’s body roll, but the RX 450h+ remains balanced. It’s clear that this is a straight-line, highway cruiser, not a carver.
Electric Range and Efficiency – 8/10
Amos Kwon
The biggest draw of the RX 450h+ is its electric-only capability. 37 miles of range means weekdays of commuting without gas when it’s combined with nightly charging. For drivers who can charge at home, it is entirely possible to go days or even weeks without visiting a gas station. Longer weekend trips won’t cause any anxiety because when the battery is depleted for EV use, it defaults to standard hybrid mode with regenerative braking.
Amos Kwon
The 2026 Lexus RX 450h+ comes equipped with a 6.6 kW onboard charger that can fully replenish the battery in about 2.5 hours when plugged into a 240V Level 2 charger, or roughly 7.5 hours using a standard 120V household outlet. It’s good to know you don’t have to get a Level 2 charger installed if you’re going to plug in the RX 450h+ as soon as you get home from work. Of course, that’s negated if you need to drive the kids around to their activities every night, as I do.
Comfort, Space, and Usability – 9.5/10
Amos Kwon
Inside, the RX 450h+ feels truly premium. While the look is more subdued than, say, BMW, the level of comfort isn’t diminished at all. Materials are soft and well-finished throughout, with careful attention paid to textures, panel gaps, and vital touchpoints. The front seats are superb. Lexus has done a masterful job balancing cushioning, support, backrest width, and seat cushion length. Hours in the front seats result in zero discomfort or fatigue.

Rear-seat passengers enjoy ample legroom and headroom, though space is competitive rather than class-leading. The huge panoramic glass roof opens and also lets in gobs of light. The battery placement slightly impacts cargo capacity compared to non-plug-in RX models, but the cargo area remains more than sufficient for everyday needs, groceries, and weekend trips. Noise isolation is excellent. In electric mode, the RX glides along quietly, and even when the gas engine is running, sound intrusion is kept to a minimum during steady driving.
Technology and Infotainment
Amos Kwon
The RX 450h+ features a large central touchscreen that serves as the hub for infotainment and vehicle controls. This top trim level comes standard with the Lexus Interface 14-inch high-resolution color screen. Wireless Apple CarPlay pairs quickly, and the system is responsive and intuitive, even if you don’t use phone mirroring. There are two big climate control knobs with integrated temperature displays, and there’s a physical audio knob, too. Although we would prefer physical controls for seat heat and ventilation, as well as for drive modes, the touchscreen system is pretty good.

I’m starting to get used to Lexus’s D-pad style steering wheel controls for audio and cruise control, but there’s definitely a learning curve. The pop-up screens show up on both the head-up display and the instrument cluster. Place your finger on the desired section of the pad, and then press and click for the function execution. You still have to divert your eyes, but you will, eventually, get used to it.

The electronic door handles take some getting used to. Those new to this setup will get confused at first. Just press the textured divot, and the door opens. In case of system failure, just pull the handle two times to get out. My kids had to show their friends what to do, a necessary violation of personal space as they reached in front of the confused kids to let them out.
Driver assistance features are comprehensive, including Automated Emergency Braking, Full-Speed Adaptive Cruise Control with Curve Speed Management, Lane-Keeping Assistance, Blind Spot Monitoring with Rear Cross-Traffic Assist, Intuitive Parking Assist with Auto Brake, Pre-Collision with Pedestrian Detection, and the optional Advanced Park with Remote Park. It’s a strong set that bolsters the already solid IIHS Top Safety Pick rating.
Final Verdict
The 2026 Lexus RX 450h+ is a thoughtfully executed plug-in hybrid that focuses on comfort, refinement, and style without rewarding driving dynamics. That said, it delivers the proven Lexus formula. Its electric range is genuinely useful, its ride quality is excellent, and its interior quality reinforces its premium price and position. You just have to figure out if you want to pay the substantial price increase for the all-electric range. It’s going to take a lot more than your period of ownership to make up the price difference in fuel savings. I say opt for the Luxury trim of the regular RX 350 Hybrid.
