2023 Lexus RX: your questions answered

All-new Lexus RX 500h

Introducing the all-new, fifth-generation 2023 Lexus RX, a completely reinvented model that opens a new chapter for the original luxury SUV. With over 3.5 million sold worldwide since its launch in 1998, the pioneering RX has become a Lexus best-seller over the last two decades and will be pivotal to the brand’s Lexus Electrified strategy.

Three electrified variants are available in Europe. The core model for the UK is the RX 450h+ featuring Lexus’s benchmark plug-in hybrid electric technology. With the new RX 350h, Lexus introduces an efficient alternative to smaller diesel and petrol powertrains. And for those drivers looking for more exhilarating performance, Lexus offers its first turbocharged hybrid model, the RX 500h, which comes with DIRECT4 drive force control.

What are the model grades?

Model grades vary slightly across the new RX range, with each equipment level having been carefully chosen to reflect buyer preference. Both the RX 350h and RX 450h+ begin with the well-specified Premium Pack, which customers can choose to enhance with either a Sunroof, Plus Pack, or Plus Pack with Panoramic Roof options. F Sport Design and F Sport Design with Panoramic Roof come next, which adopt powerful exterior styling details from the F Sport model to the established Premium Plus specification. The luxurious Takumi sits at the top of the grade structure.

Due to its performance-oriented nature, the RX 500h is exclusively available in F Sport grade, though this trim level can be additionally enhanced with a luxurious Takumi Pack.

All-new Lexus RX 450h+

Together with the recently launched NX and newly revealed RZ, RX will help build the ‘Next Chapter’ of the Lexus brand. These three models represent the strongest offensive yet by Lexus in the D-E Premium SUV market, the heart of the company’s business.  

How much does the Lexus RX cost?

The latest on-the-road prices and monthly finance options for the all-new Lexus RX range can be found on the Lexus UK website.

What powertrains is the 2023 Lexus RX be available with?

2023 Lexus RX 500h: a game-changing performance hybrid with DIRECT4 

  • 2.4-litre turbo-hybrid engine with six-speed automatic transmission and DIRECT4
    • Output: 366bhp/371 DIN hp/ 273kW
    • Torque: 645Nm
    • 0-62mph: 5.9s
    • CO2: 182-189g/km 
    • Fuel consumption: 33.2-34.5mpg

The game-changing new RX 500h is Lexus’s first turbocharged hybrid, developed to provide high-end electrified performance. 

Using a completely new hybrid architecture comprising a 2.4-litre turbo engine and six-speed automatic transmission, it delivers 366bhp. The front electric motor is positioned between the combustion engine and the transmission (which has a clutch on both sides), enabling great flexibility in power delivery.  

There is also an 80kW e-Axle, a compact, modular package housing a motor, gearing and an ECU, located between the rear wheels. Its compact dimensions help secure more space in the cabin and load compartment. 

Power delivery is controlled by DIRECT4, an exclusive new Lexus drive force technology which recently debuted on the RZ 450e. This intelligent system constantly balances the power and torque between the front and rear axles in any driving situation, automatically and seamlessly shifting the drive force between the two axles in milliseconds – more precisely than any mechanical system could.  

DIRECT4 communicates a better feel between the road and steering wheel and delivers improved handling stability and driving dynamics at high speed. Importantly for the RX 500h, it also enhances ride comfort with instant torque that helps control body movement.  

In line with the model’s high performance, the front brakes have opposed callipers. Dynamic Rear Steering (DRS) determines the optimum steering angle for the rear wheels. 

2023 Lexus RX 450h+ : the first plug-in hybrid electric RX

  • 2.5-litre plug-in hybrid electric powertrain
    • Output: 302bhp/306 DIN hp/ 225kW
    • Torque: 572Nm
    • 0-62mph: 7.0s
    • CO2: 24-26g/km 
    • Fuel consumption: 235.4-256.8mpg

Lexus drew on its electrification expertise to produce the RX 450h+ plug-in hybrid, which it believes will be a logical step-up for many of its current RX 450h customers. Expected to be the best-selling RX model in the UK and Western and Central Europe, it features a four-cylinder 2.5-litre hybrid engine and a rechargeable lithium-ion battery with 18.1 kWh capacity. An additional rear electric motor enables full-time all-wheel drive.  

The plug-in system produces 302bhp and is expected to deliver 0-62mph acceleration in around seven seconds. Overall, it offers roughly the same output as the outgoing RX 450h, but with more torque and faster acceleration. With more of the power coming from the electric motors, driving feels effortless yet refined. It will also give significantly lower fuel consumption and emissions. Lexus’s target CO2 emissions (WLTP combined cycle) are than 26g/km with fuel economy of less than 235.4mpg. 

All-new Lexus RX 450h+

The battery’s size and capacity and Lexus’s electrification know-how combine to deliver an EV driving range of around 40 miles (target figure, pending homologation) and enable all-electric driving at speeds up to 84mph. Crucially, high efficiency is maintained when the battery charge is depleted, as the vehicle then switches seamlessly to its self-charging hybrid system. 

2023 Lexus RX 350h: efficient fourth-generation self-charging hybrid 

  • 2.5-litre self-charging hybrid electric powertrain
    • Output: 242bhp/245 DIN hp/ 180kW
    • Torque: 355Nm
    • 0-62mph: 8.0s
    • CO2: 143-150g/km 
    • Fuel consumption: 41.1 – 42.2mpg
    • Performance data provisional/tentative pending homologation 

The new RX 350h is characterised by the improved smoothness and efficiency of its fourth generation self-charging hybrid electric system. This 2.5-litre petrol drivetrain provides 242b hp and 0-62mph acceleration in 8.0 seconds, performance comparable with the current RX 450h, while at the same time producing lower emissions. It will be a strong alternative to competitors with small-displacement engines and ideal for customers who prioritise comfort and efficiency.  

What is ‘Next Chapter’ Design?

Moving towards electrification, the designers undertook the challenge of incorporating the new ‘spindle body’ design identity into the new RX, achieved through stronger integration of the grille. This expresses a sense of the car’s electrified power and low centre of gravity. More compact, sharper headlights, air intakes and a wider track (+15mm) consolidate the stable, confident look.  

To achieve a bolder stance, the designers created a sleeker front-to-rear posture, extending the bonnet, lengthening the wheelbase by 6mm and lowering the roofline by 10mm. Lending the car a coupe-like feel, the signature black rear pillar (Lexus’s ‘floating roof’) is now more three-dimensional in appearance, while the sweeping character line and large 21-inch wheels heighten the dynamic feel. 

The triple LED headlights are sleeker, sharper and more horizontal in alignment. The design is accentuated by L-shaped daytime running lights. At the rear, the single-line Lexus signature tail lights underline the RX shape, while the wider track (+50mm) emboldens the stance and road presence. The introduction of the “LEXUS” badging on the tailgate creates a clean and contemporary look. 

Accentuating the RX’s sporty credentials, the F Sport version will be visually distinguished by the design execution of the grille, skirts and aerodynamic front and rear bumpers. In Western Europe the F Sport grade will be exclusive to the RX 500h performance hybrid model. 

What is the interior like on the 2023 Lexus RX?

Lexus developed the Tazuna cockpit concept to provide a more focused environment for the driver. Having first appeared in the new NX and RZ, it is now adopted for the new RX. Taking its name from the Japanese word for using reins to control a horse, Tazuna ensures direct yet intuitive control: information sources such as the multimedia screen, multi-information display, single-dial meter, centralised gauges and head-up display are grouped so their content can be read with minimal eye and head movement.  

All-new Lexus RX 450h+

“A powerful blend of Tazuna cockpit design and luxury SUV spaciousness, with materials like high-quality leathers and Takumi-crafted suede embossed with the Lexus ‘L’, is exactly the kind of bespoke look we aimed for when designing this new interior,” explains RX Interior Designer Jota Kusakari. 

The designers sought to create a minimalist, yet intuitive and thoughtful interior space. The front seats have been redesigned to offer top-class accessibility, excellent support and heating/ventilation. To provide proper ergonomic support around the waist, the sides of the seats have been given concave shape.  

One of the highlights of the new RX is the availability of a leather-like interior trim that does not use animal products, created in response to growing demand from vegan and other eco-conscious consumers. The synthetic leather is used for the seats, steering wheel and shift knob, with a choice of colours.  

All-new Lexus RX 500h

An expression of the Lexus omotenashi hospitality, the Lexus Mood Selector allows the RX’s ambient lighting to be adjusted to suit the mood or the drive from a palette of 64 colours and 14 bespoke themes. 

There is both ample luggage space and five luxury seats with excellent legroom. An increased couple distance (1010mm, +10mm compared to the previous model), new seat designs and more intelligent packaging have made the cabin feel more spacious. The luggage compartment has been made easier to access with a 30mm reduction in the loading height and is 50mm longer, thanks to intelligent tailgate design. The longer length and rear seats which split-fold 40:20:40 help accommodate bulkier items such as skis and surfboards. 

A new e-latch system electronically controls the door release operation, making it smoother and more convenient.

What is the Lexus Driving Signature?

Each RX model delivers the Lexus Driving Signature in its own way, supported by the quality of the shared platform and different powertrains. The common thread is to provide superior comfort and linear, direct responsiveness, giving all drivers control and confidence at all times. 

The new RX uses Lexus’s GA-K platform, similar to that which underpins the new NX, but with a different set-up. The rear has been completely redesigned to extend the wheelbase and accommodate additional cross members and suspension braces that increase rigidity. This increased rigidity has allowed the suspension to be more accurately tuned, improving both performance and comfort.  

The new platform has enabled a 90kg reduction in the car’s weight and a lowering of its overall height by 10mm, contributing to a 15mm lower centre of gravity. The wheelbase is longer by 60mm within in an unchanged overall length; the yaw rate has been reduced. The tracks are wider – +15mm at the front and +50mm at the rear – which, with up to 21-inch wheels, gives the RX a more confident stance and grip.  

To save weight, Lexus used advanced materials such as 2GPa high-tensile steel for the centre pillars and aluminium for the wings and bonnet. The new structure also includes 1180 MPa steel for the rocker reinforcement and 1470 MPa steel for roof rigidity.  The new multi-link rear suspension delivers better lateral stability and anti-squat characteristics, enabling a substantial hike in performance. Capable of handling higher levels of torque, it also substantially reduces noise and vibration.  

While ensuring Lexus-like quietness inside the cabin with sound-damping and vibration reduction measures, engineers and craftspeople created sounds to add a sense of power and performance. They also perfected the opening and closing sounds made by the doors.

Is there a new multimedia system on the 2023 Lexus RX?

The new RX delivers advanced connectivity that is both faster and more stable, providing the latest multimedia technology, “always connected” services and the convenience of over-the-air updates. With smartphone navigation, vehicle commands, multimedia functions and cloud connectivity, there are about 100 ways for the driver to interact with their vehicle. 

A 14-inch touchscreen, one of the largest in the RX’s class, is fitted as standard. As well as the anti-glare screen there are buttons to access the most frequently used functions. Graphics are presented in HD for excellent visibility in all lighting conditions, while the system’s CPU operates 3.6 times faster than the current one. 

Alongside an embedded navigation system, the new RX also provides cloud services as standard (in markets where the service is available). The car’s DCM (data communication module) provides always-on connectivity, with access to live information on traffic events, accidents and road conditions.  

The new multimedia system includes a smart voice assistant, ‘Hey Lexus’. that responds to questions and commands given in a more natural style of language. Easy smartphone integration is provided as standard – wireless for Apple CarPlay and with a wired connection for Android Auto. A wireless charging tray is available, with 50 per cent quicker charging performance. 

All-new Lexus RX 450h+

In addition to established Lexus Link remote functions such as driving analytics, hybrid coaching, fuel level monitoring and “find my car” function, new functions are available for the RX 450h+: monitoring the level of battery charge, scheduling charging and a charging timer. The app also allows remote locking and unlocking of the vehicle, opening the tailgate, operating the climate control and activating the hazard lights so the RX can be spotted in a car park. 

High-grade versions of the RX come as standard with a new 21-speaker Mark Levinson Premium Surround Sound audio. Developed by Lexus’s exclusive audio partners, the system is optimised for the car’s interior architecture.  

What is ‘Advanced Driver Support’ on the 2023 Lexus RX?

Lexus introduces many advanced human-centred technologies in the 2023 RX to enhance comfort, convenience and life on board, reinforcing the spirit of omotenashi hospitality. The RX can be specified with a digital rear-view mirror which gives the driver a wide, unobstructed field of vision, using real-time images from the car’s reversing camera.  

All-new Lexus RX 500h

For easier driving in confined spaces, the Digital Panoramic View Monitor uses cameras to capture a live 360° view around and a pre-recorded view under the car (the cameras now benefit from automatic cleaners). It also creates a virtual 3D image of the RX, showing the vehicle as if seen from above.  

An Advanced Park system is also available, developed from that on the Lexus LS flagship saloon. It provides automated control of the steering, shift operation and braking and uses the car’s array of four cameras and 12 ultrasonic sensors to gain an all-around picture of the immediate surroundings. It will also recognise up to three regularly used parking spots.  

 The new 2023 RX benefits from next-level active safety and driver assistance systems featured in the latest generation of Lexus Safety System+ with upgraded functions and increased scope for accident risk detection and prevention.  

The improvements include further expansion of the Pre-Collision System’s ability to detect motorcycles and other objects in the car’s path. It can also recognise collision risks with oncoming traffic or crossing pedestrians when making a turn at a junction. Its detection response is quicker and the ability to avoid an impact is increased by Emergency Steering Assist.  

Enhancements have been made to the Adaptive Cruise Control so that it now more quickly recognises traffic cutting in front and, in conjunction with upgrades to Lane Trace Assist, follows a more natural line through bends. The ACC has also been expanded to respond to more signs and commands, including warning signs and STOP signs. 

While Lexus Safety System + is fitted as standard on all European models, owners of higher-grade models can choose an Extended Safety Package. This includes Lane Change Assistance (LCA), which provides automatic lane change steering on the motorway and Front Cross-Traffic Alert, which uses radar monitoring to warn the driver of traffic approaching from either side. 

A feature new to the RX, Pre-Collision System with Active Steering Assist, determines when there is a high possibility of collision with a pedestrian ahead or with an object. If the system also determines that it is difficult to avoid the collision with brake control alone – but that it might be avoided using steering control –Active Steering Assist is deployed, in addition to braking and the triggering of an alert. 

Proactive Driving Assist helps maintain a safe distance to cars in front – even when cruise control is not engaged – and it helps the driver to avoid pedestrians and obstacles. 

The Driver Monitor uses a camera mounted above the steering wheel to constantly check the condition of the driver. It can slow or stop the car if driver doesn’t react to alerts. 

The RX’s e-latch electronic entry and exit system are linked to the car’s Blind Spot Monitor to provide a Lexus-exclusive exclusive Safe Exit Assist function. This prevents the door from being opened if cars or cyclists are detected, approaching from the rear. Lexus estimates this system can help prevent more than 95 per cent of the accidents caused by inadvertent door opening.

  1. What protection is designed for the 450h+ catalytic converter? Previous models have had easily accessible CCs just under one side.

      1. If the vehicle has not been bought it wont yet have a reg but the question stands – what
        has been done to protect against cc theft?

        1. Hello Mark, thanks for your question.

          You can have a CATLOC installed at your Lexus Centre, as a protective measure against Catalytic Converter theft. We would recommend contacting your Lexus Centre to discuss fitment of this.


          1. So Lexus has made no attempt to design out this costly and (if theft happens, inconvenient too) flaw in the latest generation RX? Doesn’t say much for Lexus and its commitment to customer satisfaction does it?
            Is there a diagram you can share of the exhaust and cat setup in the new 450x+?

          2. Hello Mark, thanks for your comment.

            We have sent you an email with the diagram, as requested.


        1. Hello John, thanks for providing this information.

          Our Technical team have advised us that this vehicle’s catalytic convertor is placed under the exhaust manifold.

          This makes it much more difficult for thieves to commit theft and strengthens the car’s security.


  2. Does the Lexus 450h+ use the lithium ion battery for hybrid driving when there is insufficient charge for pure EV driving?

    Is there a separate nickel-metal hydride battery?

    What voltage is the petrol engine starter motor and is there also a 12v battery?


    1. Hello Richard, thanks for your question.

      Our Technical Team have advised that the vehicle uses a lithium ion battery. The homologated EV driving range is 42 miles, with all-electric driving possible at speeds up to 80mph.

      In answer to your final question, there is no starter motor but there is a 12v battery.


  3. Hi, I am thinking of buying a new RX 450h+ Takumi, I do not have a registration number.
    I think the new seats are a great. I am told that it drives even better than the previous version.
    I wonder if you could help me with the following:
    What protection is there against catalytic converter theft please?
    Is the car vulnerable to the CANBUS theft mode by accessing electronics via the front nearside wheel arch please?
    Is it possible to purchase a Takumi version with 19” wheels rather than the standard 21” wheels?
    Thank you for your help.

    1. Hello John, thanks for your interest in the Lexus RX.

      Modern vehicles invariably come with a high level of built-in security but as with any model in our range, we would always recommend extra measures to protect your car from theft. Here are our top recommendations for improving car security to reduce the risk of becoming a victim to crime: https://fal.cn/3wm1C.

      In regards to your question about the wheels, from standard, the Takumi only comes with 21″ wheels, however, you can get 19″ wheels as an accessory.


      1. Hi, Thank you for the information.

        Please is there a brochure or similar for the 2023 RX with comprehensive information on it, similar to the detailed document on the NX?

        On the Lexus site there is no document with very detailed information.

        Thank you

          1. Hello John, thanks for your question.

            The brochure for the Lexus RX is the link that we provided in the previous comment. This lists the different specifications across grades of the new RX.


  4. Is it possible to get a lightweight spare wheel for the new RX plug in hybrid with 21” wheels?

    Is there a supply problem with a tow hitch for the new RX 450h+?

    There is no registration number


    1. Hello Richard, thanks for your comment.

      Our Accessories Team have advised that there is currently no spare wheel available for this vehicle.

      In regards to your second question, due to supply issues, a tow hitch is not available for the RX.


  5. Hi. My new RX 350h premium plus due in June does not come with a spare tyre. A company that provides space savers has offered one to fit this car. The car comes with 21” alloys 235/50 r21 as standard. Can you confirm if a space saver will fit in the boot floor. The dimensions are 155/85R19 for the space saver. There appears to be a large block of plastic or foam to remove in order to fit a spare. The tyre repair kit is useless as it means the tyre cannot be permanently repaired and must be replaced. It also cannot seal a tear and a chronic oversight for our travels round Europe where a spare is essential. Can you also please advise availability of a tow ball for a bike rack which is essential to fit at the point of delivery. Please also advise that the spare will fit.

    1. Hello Martin, thanks for your question.

      A space saver spare wheel is not available for the Lexus RX. We cannot advise on accessories from other suppliers.

      Tow bars are available for this vehicle. We would recommend contacting your Lexus Centre regarding this, in order to modify your order.


  6. Hi, I have an RX450h+ with a tow bar fitted upon which I use a cycle carrier.. I’m surprised that when the tow bar is installed and the lighting circuit is enabled that the reversing emergency brake and the reversing sensors are not automatically deactivated. I need to manually deactivate them and then reactivate when the carrier is removed.
    Can I please propose that a future software update would automatically deactivate the two systems when the lighting circuit is activated?

    Regards Kevin

    1. Hello Kevin, thanks for your comment.

      We value your feedback greatly and wish to thank you for this suggestion. We will pass this on to the relevant teams.


      1. Hello and thank you for your reply. I have a further enquiry; my car was delivered in May but I am still awaiting the additional keys (second and card keys). My dealer doesn’t know when they will arrive. Can you help please?

        1. Hello Kevin, thanks for getting back in touch.

          You’re very welcome for the reply, we value any feedback you have for us greatly.

          Unfortunately, your Lexus Centre is best placed to advise on the availability and ordering of additional keys. They will have the most up-to-date information for you. We understand this can be frustrating and thank you for you patience.

          Please let us know if you have any further queries.


          1. Hello again, I have a further question please.
            I use the Road Sign Assistance driver aid and set the notification method to Visual. I have also set the Excess speed notification level to 5mph, however the excess speed warning is still triggered at only 1mph over the speed limit. Can you please explain why this would be and exactly what the Excess speed notification level setting is for if not to allow a small margin of overage without triggering the warning?
            FYI I have also asked my local dealer/centre but they experienced the same result as me in a similar Takumi and have not been able to get an explanation yet.
            Regards, Kevin

      1. My question of 20th November has now been answered by Lexus Europe following a message I sent directly to Lexus customer service. I’m disappointed that it has taken this long for you to respond.

  8. Hello, I purchased a Lexus RX 500h from Glasgow on August 3rd. The local center in Glasgow mentioned they don’t have any updates and advised me to check directly with Lexus regarding the availability of my second car key, key card, rear rubber mat, and mud flaps. Could you please provide me with an update on when I can expect these items?

    1. Hi Vinay, thank you for getting in touch.

      The availability of these items is on a case by case basis. Please confirm your registration number so we can check on this.


      Lexus UK

        1. Hi Vinay,

          Your second key is now available to order under campaign code YHG14. Please get in touch with your local Lexus Centre to arrange and the team will also be able to check on the other elements.


          Lexus UK

          1. Thank you for your response. Will I also be receiving a keyless card (fob) along with the second key? I wanted to inquire about the rear floor rubber mats. I was provided with fabric ones, which are challenging to maintain during rainy and snowy weather. After conducting online research, I found that they are not available in any stores (Lexus RX500h 2023). I need them urgently.

          2. Hi there,

            Your local Lexus Centre will be able to look into the options now available. Although, we can confirm that we currently do not manufacture rubber floor mats for the rear of this model at the moment.

            We will pass your feedback onto our Accessories Team.


            Lexus UK

  9. Hi
    Can you please confirm if a detachable tow bar with 13 pin electrics is available for the RX450h+ with a Premium Plus pack. I am considering purchasing this model but need to confirm I will be able to tow my caravan with it.

    1. Hi Trevor, thanks for your comment.

      We have previously had struggles in sourcing towing hitches, however this is now resolved.
      Your local Lexus Centre can help run through the specification options suitable for towing.
