As one tester put it after several hundred miles behind the wheel: “I didn’t want to give the keys back after putting several hundred miles on a shimmering silver RX 450h+ in aptly named Luxury trim.” That sentiment captures the SUV’s appeal better than any spec sheet ever could.
Electrified Simplicity With Real-World Strength
At its core, the Lexus RX 450h+ combines a 2.5-liter naturally aspirated inline-four engine with dual electric motors and a lithium-ion battery pack positioned under the rear seats. The result is a combined output of 304 horsepower delivered to all four wheels, with the rear axle driven exclusively by electric power.
Performance is brisk without being aggressive. Lexus quotes a 0–60 mph time of 6.2 seconds and a top speed of 124 mph, but the real story is how seamless the acceleration feels in everyday driving. Electric torque fills in the gaps left by the non-turbocharged engine, giving the SUV an effortless surge, especially at highway speeds.
It’s not trying to be a sports SUV—and it doesn’t need to be. Instead, it prioritizes smoothness and predictability.
Electric-First Driving With Hybrid Safety Net
The plug-in hybrid system is where the RX 450h+ shows its strongest character. On a full charge, Lexus estimates up to 38 miles of electric-only driving, a figure that makes short commutes and daily errands possible without burning fuel.
In real-world use, the reviewer noted: “I saw close to 40 miles of all-electric range on a full charge.” That’s enough to make electric operation the default mode for many drivers, especially those who can charge at home.
Charging is also straightforward. A Level 2 setup can replenish the battery in roughly 2.5 hours, making overnight or workplace charging practical rather than inconvenient.
Once the battery is depleted, the system transitions into hybrid mode, where Lexus claims up to 35 mpg combined—an impressive figure for a 304-horsepower luxury SUV.
Built for Calm, Not Chaos
The driving dynamics reinforce the RX’s relaxed personality. Steering is described as “quick and direct, with reasonable heft,” giving it enough precision for highway stability while remaining light enough for tight urban maneuvers.
Ride quality is where the SUV truly stands out. Even with large 21-inch wheels, typically a compromise for comfort, the suspension absorbs imperfections with surprising composure. As the reviewer noted, “It’s one of the most pleasant rides around.”
This is not a vehicle designed for sharp corner carving or aggressive driving. It’s tuned for long-distance comfort, low fatigue, and an almost hushed driving experience.
A Cabin Designed Like a Private Lounge
Inside the Lexus RX 450h+, Lexus continues its focus on craftsmanship and sensory comfort. Semi-aniline leather seats, both heated and ventilated, set the tone, while a 14-inch touchscreen anchors the dashboard with wireless Apple CarPlay and Android Auto support.
The materials elevate the experience further. Bamboo trim stretches across the dash and doors, and a suede-like headliner adds an unexpected softness overhead. The effect is intentional: a cabin that feels closer to a modern lounge than a traditional SUV interior.
One description summed it up neatly: the materials created a “resort-like feel every time my hand brushed across it.”
Optional upgrades in the test vehicle included a 21-speaker Mark Levinson audio system and a digital rearview mirror that streams live footage from the rear camera. Driver assistance systems also help maintain lane position on highways, though they stop short of full hands-free capability.
The only criticism inside the cabin centers on the digital instrument cluster, which can feel overly dense. The reviewer described it as “information overload,” making it difficult to quickly isolate essential driving data.
Space That Works Without Compromise
Practicality remains a strong suit. Rear passengers benefit from generous legroom and wide-opening doors, making entry and exit easy even in tight parking spaces.
Cargo capacity stands at 29.6 cubic feet behind the rear seats, expanding to 46.2 cubic feet when folded flat. Notably, these figures remain unchanged across the RX lineup, including the plug-in hybrid variant.
In short, electrification hasn’t come at the expense of usability—a key advantage in this segment.
Luxury With a Price Tag to Match
With an as-tested price of $76,965, the Lexus RX 450h+ sits firmly in premium territory. Standard and optional features bring it into direct competition with other luxury plug-in hybrid SUVs, but Lexus differentiates itself through refinement rather than flash.
The verdict from long-term time behind the wheel is less about numbers and more about emotional impression. It’s a vehicle that doesn’t demand attention but earns appreciation through consistency, comfort, and ease of use.
And as the reviewer concluded: “No wonder I still miss its presence.”
