A sporty exterior design

A plug-in model with 37 miles of electric driving range

A longer driving range with both fuel and gasoline

Great power and acceleration

Roomy interior

A 14-inch infotainment touchscreen is available

Panorama roof available with a power sunshade

A high-end Mark Levinson Audio System

Heated and ventilated front and rear seats

A radar active cruise control system with co-pilot assist

A low speed hands free traffic assist driving system

Heads Up Display (HUD)

Wireless Apple Carplay

An optional digital latch with safe exit is designed to prevent the door from opening and warn of motorists and cyclists approaching

The optional digital rearview mirror increases one field of vision

Wireless phone charging

A high level of safety driving aids

An advanced optional automatic parking system

A variety of driving modes


The front fascia is still somewhat polarizing

A complicated infotainment system requires voice activation to control many of the functions.

Driver’s seat needs more back support

The layout and design of the digital instrument cluster and infotainment system needs to be thoughtfully integrated into the vehicle like in the Genesis and Audi brands.

No front wheel drive model on the 450h

The vehicle rides firmer than one would expect from Lexus

Towing capacity is significantly lower than other RX gasoline only models

Verdict: Unlike Mercedes-Benz and Volvo, Lexus has taken a cautious approach in terms of electrifying its brand. In 2023, Lexus added its only fully electrified vehicle, the compact RZ. The RZ shares a platform with Toyota and Subaru. And now the larger RX is making its push toward electrification.

Unlike the smaller RZ, which is all-electric, the RX like the compact NX and TX, is now available in a plug-in configuration. This means for many buyers, who are somewhat hesitant about jumping in the all-electric world, they will have the best of both worlds, gasoline and electrification.

On a full charge, the peppy 304-horsepower RX can achieve upwards of 37 miles, before the gasoline engine kicks in. When the gasoline engine takes over, the RX plug-in can achieve over 500 miles of non-stop driving, before needing to refuel and/or recharge. We’re still waiting for, a federally operated website, to release their finding on the mileage.

For comparison sakes, Lexus’ RX 350h luxury trim, which has a 619-mile driving range, according to, has a starting price of $61,000. While the horsepower in the RX 350h is somewhat underwhelming, the peppy RX 450h, which is a plug-in, starts out the gate near $71,000. At $71,000, this makes the RX the most expensive RX to date.

On the hand, when comparing the RX plug-in to its direct competitors, the Volvo XC60 Recharge and BMW X5 sdrive50e, we notice a drastic difference in the price. The Volvo XC60 and BMW X5 sdrive50e offers a 36-and 39-mile driving range, respectively. The Volvo and BMW has starting prices at $59,125 and $74,095, respectively. 

Moreover, Mercedes-Benz is the only automaker who has a fully electric vehicle in the midsize luxury segment, the EQE 350. Out the gate, the base EQE is priced at $79,050.

There is also the compact Genesis G70 Electrified to consider. The luxurious all-electric vehicle has a starting price under $68,000. 

While the price point of the RX 450h is more aligned with the BMW X5 xdrive50e, which are both plug-ins, we can only imagine the price point of the RX once the model becomes all-electric.

Outside of the electrification, the current generation RX, which debuted during the 2023 model year, mirrors that of the plug-in. Our test model offered a firm ride and all of the latest luxury accoutrements one has come to expect from the luxury brand. As in other Lexus models, we were somewhat frustrated by the subscription-based navigation system and the audio system. Lexus is counting on the users to rely on the inconsistent voice-activated system to operate the infotainment system.

With that said, will those seeking an electrified Lexus be willing to pay for the plug-in, which qualifies for federal incentives, steer toward the RZ, which offers heavy incentives, are just steer clear of the plug-in and/or possibly seeking out a non Lexus brand. Time will tell, while Lexus takes more of a cautious approach to electrifying their vehicles.

Plug-In Competition: BMW X5 xDrive50e and Volvo XC60 Recharge
