As the best-selling nameplate for one of the most revered premium brands in the United States, the Lexus RX crossover SUV is an extremely important vehicle in the Japanese automaker’s lineup. It’s also something of a pioneer, introducing hybrid technology to the premium sector many years ahead of most rival brands. Arriving for the 2006 model year, mid-way through the lifespan of the second-generation RX, the RX 400h was way ahead of its time.
Two decades later, Lexus offers three distinct RX hybrid SUVs. The RX 350h is the least expensive RX hybrid in the current lineup, while the RX 500h is the high-performance offering. Buyers who want the longer pure-electric range of a plug-in model can choose the RX 450h+ Plug-In Hybrid.
Whatever the version, the Lexus RX offers a comfortable ride and a luxurious interior filled with technology. An extended-length RX L model was available for a few years, but its comparatively small third row wasn’t big enough for regular use. The Lexus TX took on the role as the brand's proper three-row luxury SUV from the 2024 model year.
Our guide to the Lexus RX Hybrid looks at the model’s history over the years, the best and worst versions to buy, and how much buyers can expect to pay. The RX Hybrid was introduced as part of the second-generation RX range, so the model generations are one behind the wider RX range—check out our Lexus RX buying guide for more.

Frequently Asked Questions
Which Lexus RX Hybrid years are the best?
The Lexus brand has a well-earned reputation for reliability, and RX Hybrid crossovers have proved reliable across all four generations. Nonetheless, newer, low-mileage models are likely the best bets. Buyers wanting a plug-in crossover will have to look for an RX 450h+ model. These are relatively new and therefore still on the pricey side.
What are the worst Lexus RX Hybrid years?
Since there haven’t been any particularly unreliable Lexus RX Hybrid models, the nameplate’s “worst” years are its first three, only because the RX 450h that replaced the original 400h is a better overall vehicle.
Is a used Lexus RX Hybrid a good deal?
Yes, the Lexus RX Hybrid can be a good deal on the used market. Vehicles wearing the Lexus badge tend to hold their value well, but second-gen RX Hybrids from 2010 to 2015 can be found for well under $20,000. The third-generation RX Hybrid, which was built between 2016 and 2022, also represents a solid deal in the $25,000 to $30,000 range.
A used Lexus RX Hybrid with reasonably low mileage should be reliable for years to come. We suggest potential buyers take a test drive of both the vehicle and its infotainment system, which, for many years, used an odd mouse-like knob that takes some getting used to.

Lexus RX Hybrid Generations
Lexus RX Hybrid Fourth Generation (2023-Present)
Lexus completely redesigned the best-selling RX luxury crossover for the 2023 model year. It rode on a new platform that was stiffer and lighter than the one it replaced, and although overall exterior dimensions remained roughly consistent with the previous generation's, interior space was up due to a longer wheelbase and a little more width. Powertrain options also changed dramatically. In place of the bread-and-butter RX 350’s V6 was a 2.4-liter turbocharged four-cylinder producing 275 horsepower.
The RX 350h—the lower-case letter signifying a hybrid powertrain—was also all new for the fourth generation, with a naturally aspirated 2.5-liter four-cylinder engine and electric motor combination that combined for standard all-wheel drive (AWD) and a total system output of 246 hp. Although down on power compared with the non-hybrid version, the RX 350h’s EPA-estimated fuel economy ratings of 37 mpg in the city, 34 mpg on the highway, and 36 mpg combined beat its more powerful sibling’s ratings of 21 mpg city, 28 mpg highway, and 24 mpg combined.
Buyers looking for a blend of power and efficiency could opt for the 2023 RX 500h F Sport Performance AWD SUV. Its 2.4-liter turbo engine and front motor, along with an 80-kW rear electric motor, produced a combined 366 hp and 406 pound-feet of torque. Even with all that power on tap, the RX 500h returned 27 mpg combined. As an added bonus, the RX 500h is the only version with standard four-wheel steering, which cuts its turning circle down to match that of many small hatchbacks.
Lexus used the debut of its fourth-generation RX to launch the nameplate’s first plug-in hybrid powertrain. The addition of a large-capacity 18.1-kWh lithium-ion battery pack allowed the RX 450h+ to travel up to 37 miles per charge on electric power. A recharge of the battery took about 2.5 hours on a 240-volt outlet, but a regular 120-volt outlet could also be used when necessary. Due to its revised plug-in powertrain, the RX 450h+ was more powerful than the RX 350h that used the same engine, with total system output coming in at 304 hp.
The 2023 Lexus RX 350h lineup started with the base AWD version that came standard with 19-inch alloy wheels, three-zone automatic climate control, heated and power-operated front seats, faux leather upholstery, and a 9.8-inch touchscreen infotainment system that supported wireless Apple CarPlay and Android Auto. The RX 350h Premium trim level added extras such as a sunroof and roof rails, wood interior trim, ventilated front seats with memory positioning, a wireless smartphone charger, and front and rear parking sensors. Premium+ models gained upgraded interior lighting, a higher-quality leather interior, and a larger 14-inch infotainment system.
The RX 350h Luxury trim level gained 21-inch wheels, synthetic suede interior trim, perforated leather seating surfaces, and a head-up display. The 2023 RX 350h lineup concluded with the F Sport model that looked sportier but didn’t have any additional power. In addition to unique exterior styling, the RX 350h F Sport featured 21-inch wheels with a gloss-black finish, an active suspension system, unique front seats and steering wheel, and faux leather upholstery. Oddly, the F Sport reverted to the smaller 9.8-inch display but kept the Luxury trim’s head-up display.
The only trim level offered for the 2023 RX 500h was called F Sport Performance. It came loaded with pretty much all the options available on lower-grade RX models, but again the 14-inch infotainment system was an extra-cost option.
Regardless of trim level, all fourth-generation Lexus RX models came standard with the Lexus Safety System+ 3.0 suite of safety tech. Included in the package were a Pre-Collision System designed to detect imminent contact with something ahead, Proactive Driving Assist that could gently brake or steer the RX when necessary, Lane-Departure Alert with Steering Assist, Lane-Tracing Assist (lane centering), Road-Sign Assist, All-Speed Dynamic Radar Cruise Control with Curve Speed Management, and Intelligent High-Beam headlights.
The Lexus RX 450h+ Plug-In Hybrid came later than other variants and was badged as a 2024 model. It included the features in the RX 350h Luxury trim level, which meant it came with the superior 14-inch infotainment screen. There weren’t any other significant changes for the 2024 model year.
Lexus introduced a new RX 500h Black Line Special Edition package for 2025 that came with black exterior elements, orange brake calipers, and 21-inch split-five-spoke wheels. Inside, the Black Line was, predictably, trimmed in black leather highlighted by gray stitching. The RX 350h got a new F Sport Design package for 2025, which included an updated grille and front fascia, along with gloss-black 21-inch, 10-spoke alloy wheels.
For the 2026 model year, Lexus added an Appearance Package with blacked-out exterior elements for F Sport models that emulated the previous year’s Black Line Special Edition model and a wireless phone charger became standard across the lineup.
At the time of writing, pricing for the 2026 Lexus RX 350h started at $54,275 including destination and extended to $73,310 for the RX 450h+ Plug-In Hybrid Luxury model. Used prices for this latest RX Hybrid model start at about $41,000, which will bag a car with about 50,000 miles on the odometer.
Lexus RX Hybrid Third Generation (2016-2022)
An all-new Lexus RX 450h debuted for the 2016 model year with much more angular styling, a large spindle-shaped front grille, and heavily contoured body sides. While it was a ground-up redesign with a longer wheelbase that provided more interior space inside, RX qualities such as a quiet and comfortable ride, a well-crafted interior, and strong fuel efficiency remained intact.
The RX 450h combined a 3.5-liter V6 engine and two electric motors to offer 308 hp and 247 lb-ft of torque. RX Hybrids equipped with the Lexus E-Four all-wheel drive system received an extra electric motor to power the rear wheels. There was no direct connection from the engine up front to the wheels in the back in AWD models. Fuel efficiency was solid at 31 mpg in the city, 30 mpg on the highway, and 30 mpg combined for FWD models. AWD RX models got 30 mpg in the city and 28 mpg on the highway but were still rated at 30 mpg combined.
From 2016, a new F Sport package was offered on RX 450h models with AWD. As well as a more aggressive exterior appearance with 20-inch wheels, the F Sport kit included adaptive variable suspension and a Sport+ drive mode setting that adjusted the steering feel and suspension tuning.
Inside, base RX 450h models were equipped with an 8-inch infotainment screen, but most RX Hybrids benefited from a larger 12.3-inch unit. Lexus’ Remote Touch Interface controlled functions using a knob on the center console that moved around like a computer mouse, although many users found it less intuitive than a touchscreen.
Although it wasn’t standard across the entire RX lineup, the Lexus Safety System + suite of active safety features was available. The package included Pre-Collision System with Pedestrian Detection, Lane-Departure Alert with Steering Assist, Intelligent High-Beam lights, and All-Speed Dynamic Radar Cruise Control. Blind-spot monitors with rear cross- traffic alert were also available.
For 2017, Lexus made its forward-collision warning, lane-keep assist, high-beam assist and adaptive cruise control functions standard across the RX 450h lineup. The Lexus Enform Connect smartphone application was added in 2019.
Lexus updated the RX Hybrid’s styling for the 2020 model year and retuned the suspension. The infotainment system was upgraded, too, with a slightly more intuitive trackpad and touchscreen interface for the 12.3-inch screen. Apple CarPlay and Android Auto were new for 2020, although a wireless charging pad didn’t come until 2021. An optional Black Line appearance package was offered for the 2022 RX 450h, which would be the final year for the hybrid model’s third generation.
Buyers can pick up high-mileage examples of this generation of RX Hybrid from about $19,000, but should expect to pay at least $28,000 for one with less than 70,000 miles on the clock.
Lexus RX Hybrid Second Generation (2010-2015)
The Lexus RX Hybrid got more than just a name change for the 2010 model year. What was previously known as the RX 400h became the RX 450h due to its new powertrain that combined a 3.5-liter V6 engine and a pair of electric motors. Overall output was up to 295 hp, an improvement of 27 hp over the previous model. Fuel efficiency also increased, with EPA-estimated ratings of 32 mpg in the city, 28 mpg highway, and 30 mpg combined for FWD models or 30 mpg city, 28 mpg highway, and 29 mpg combined with AWD.
A new EV Mode was adopted for 2010, which allowed the RX 450h to hit speeds up to 30 mph using only electricity, although in reality the gasoline-fueled engine kicked in to help fairly often. Lexus’ mouse-like Remote Touch interface for the infotainment system also debuted in 2010.
While 18-inch alloy wheels were standard for the 2010 RX 450h, a Sport Package swapped those to 19-inch units and included a retuned suspension setup for a sportier experience. A Premium Package with leather seating surfaces, a sunroof, and power liftgate was also available. The Comfort Package added adaptive headlights and front seats with heat and ventilation, while a Luxury Package came loaded up with nearly all the goodies Lexus had to offer in 2010.
The Sport Package only lasted one year, and was discontinued for 2011. Lexus’ spindle-shaped grille first appeared on the RX Hybrid line for 2013, though it was fairly mild compared with some of the subsequent designs. A Sport mode that tightened up the RX 450h’s reflexes was also added in 2013. The 2014 model year would be the final one for the second-generation Lexus RX Hybrid.
Shoppers can find mega-mileage examples of this RX Hybrid for $7,000 or less, but should budget at least $15,000 for one that’s covered no more than 80,000 miles.
Lexus RX Hybrid First Generation (2006-2009)
When Lexus launched the RX 400h for the 2006 model year, the well-appointed premium crossover was the first hybrid vehicle from a luxury brand in the United States. This first-generation RX Hybrid (part of the second-generation RX range) added power and increased fuel efficiency in one stroke. Based on the RX 330 SUV, it used a 3.3-liter V6 engine mated to multiple electric motors to produce 268 hp. That was 38 hp more than the RX 330’s V6 engine. Those ponies were sent to either the front or to all four wheels through a continuously variable transmission.
The EPA estimated that the 2006 RX 400h would return 28 mpg in the city, 25 mpg on the highway, and 27 mpg combined. With all-wheel drive, those numbers dropped only slightly to 27 mpg city, 25 mpg highway, and 26 mpg combined. Compared with the 19 mpg combined rating of the AWD RX 330, the RX Hybrid was significantly more fuel-efficient.
Lexus cut down the number of standard features for the 2007 model year in an effort to make the RX Hybrid a bit less expensive and therefore attainable to more buyers, but very few changes came to the RX 400h until it was replaced by the RX 450h for the 2010 model year.
There are plenty of used RX Hybrids of this era available for less than $5,000 and many have covered more than 200,000 miles. That’s an advertisement for Lexus reliability right there. Cars with under 100,000 miles on the clock start at about $9,000.
