The December holiday period has a way of changing how you interact with a car. Journeys are longer, routines are looser, and expectations shift from efficiency to comfort and ease. Spending four uninterrupted weeks with the Lexus RX 450h+ offered a rare opportunity to understand not just how it drives, but also how it fits into everyday life when the pace slows, and the kilometres quietly add up.
Receiving a vehicle for an extended test is always a bit of a lottery. Sometimes it is expected, sometimes it is overdue, and every now and then it is a genuine surprise. Taking delivery of the Lexus RX 450h+ at the beginning of December fell squarely into the latter category. A full month with a premium plug-in hybrid SUV over the festive season is not something one takes lightly.
There was also a personal element to this test that made it more meaningful than most. I have always had a soft spot for the Lexus RX. Over the years, our family has owned three examples, each quietly reinforcing the model’s reputation for comfort, durability, and a sense of calm that very few SUVs can replicate. The RX has never tried to shout the loudest in its segment. Instead, it has consistently gone about its business with an understated confidence that tends to grow on you the longer you live with it.
A BRIEF RX BACKSTORY IN SOUTH AFRICA
The RX has been part of the South African luxury SUV landscape for more than two decades, arriving at a time when the idea of a premium crossover was still finding its feet. Long before electrification became fashionable, Lexus positioned the RX as a refined alternative to traditional executive sedans, and later as a pioneer in hybrid technology. South Africa was an early adopter of Lexus hybrid models, and the RX has played a central role in that journey, becoming something of a poster child for the brand’s electrified ambitions.
Today’s RX range reflects how far that thinking has evolved. The current lineup consists of six derivatives, spanning conventional hybrid power, plug-in hybrid technology, and performance-focused options. Introduced to the local range about a year before this driving test, the RX 450h+ sits near the top of the tree, below the RX 500h F Sport and F Sport Black Edition. For my money, it represents the sweet spot of the range. It balances power, performance, efficiency, and price in a way that feels truest to the RX ethos.
ELECTRIFICATION LEXUS STYLE
At the heart of the RX 450h+ is a familiar Lexus formula, albeit one that has been significantly evolved. The plug-in hybrid system pairs a 2.5-litre petrol engine with electric motors and a lithium-ion battery pack, delivering a combined output of around 227 kW. Power delivery is smooth, progressive, and entirely unflustered.
Over the four weeks I spent with the RX, I covered just over 1,400 km. In that time, the onboard computer barely budged from an overall fuel consumption figure of 7.4 l/100 km. That is a remarkable result for an SUV of this size and weight, and it speaks volumes about how well Toyota and Lexus have refined their hybrid systems over the years. Simply put, they remain the benchmark in standard production vehicles.
Charging the RX is refreshingly straightforward. Plugging it in at home quickly becomes part of the routine, and for city use, the system makes a lot of sense. The claimed electric-only range of 66 km is optimistic, though, particularly in typical city conditions with traffic, air conditioning, and the occasional heavy right foot. That said, even a more realistic real-world figure still allows for meaningful electric driving during the week, with the petrol engine stepping in seamlessly when needed.
SIMPLY EFFORTLESS
One of the RX’s enduring strengths has always been its ride quality, and the 450h+ does nothing to tarnish that reputation. The suspension strikes an excellent balance between compliance and control, soaking up poor road surfaces without ever feeling floaty or disconnected. Long-distance cruising is where the RX truly shines, with low noise levels, excellent seat comfort, and a general sense of isolation from the outside world.
Performance is more than adequate, with strong mid-range response and confident overtaking ability. While it is not chasing outright pace figures in the way something like the Volvo XC60 T8 does, the Lexus delivers its performance in a far more relaxed and predictable manner. Even compared to larger, more powerful options such as the BMW X5 xDrive50e, the RX never feels out of its depth in everyday driving. It simply goes about its work quietly and competently.
SETTING THE TONE FOR COMFORT
If there is one area where the RX 450h+ truly excels, it is the interior. This is a tour de force in modern Lexus design. Sumptuous, refined, and elegantly executed, the cabin manages to feel both welcoming and special every time you climb aboard. The leather seats are beautifully comfortable, with heating and ventilation up front, and they remain supportive even after several hours behind the wheel.
The attention to detail is unmistakable. Materials feel expensive, surfaces are soft to the touch, and everything you interact with has a reassuring sense of quality. The Bowers and Wilkins sound system is a standout feature, delivering rich, immersive audio that turns even mundane journeys into something to savour. Rear seat passengers are well catered for too, with their own climate control and generous levels of space.
Onboard technology works as it should, which sounds like faint praise until you consider how often that is not the case in this segment. The infotainment system is intuitive, responsive, and free of unnecessary gimmicks. Lexus has clearly focused on usability, and it pays off in day-to-day driving.
There is also that intangible Lexus aura that’s difficult to quantify but easy to feel. It is a sense that the car has been engineered with care and consideration, rather than simply assembled to meet a specification sheet.
WHEN PRACTICALITY TAKES A HIT
Spending four weeks with any car has a way of revealing its flaws, and the RX 450h+ is no exception. While it is difficult to fault on ride quality, performance, or efficiency, practicality does take something of a hit. The reason lies squarely with the plug-in hybrid powertrain.
Unlike its internal combustion-only and standard hybrid siblings, the RX 450h+ houses its larger battery pack beneath the boot floor, occupying the space normally reserved for a spare wheel. As a result, the spare wheel is strapped into the boot itself. Its awkward size and placement reduce usable luggage space by at least 40% when the rear seats are in use. In a vehicle of this class and price, that is a meaningful compromise.
One should not have to choose between luggage capacity and something as crucial as a spare wheel. It is an awkward solution, and one that detracts from an otherwise well-resolved package. That said, context matters. The RX is far more likely to serve well-to-do families in urban environments than to be used for long-distance travel with a full complement of passengers and luggage. In that scenario, replacing the spare wheel with a puncture repair kit could be a pragmatic solution, reclaiming much of the lost space.
SAFETY AND SERENITY
Safety is, as expected, of the highest standard. Lexus equips the RX with a comprehensive suite of driver assistance systems that operate unobtrusively in the background, providing reassurance without constant intervention. Over the course of my time with the car, these systems worked seamlessly, contributing to an overall sense of calm and confidence behind the wheel.
There is peace of mind in knowing that you and your passengers are well protected, and Lexus continues to set a high bar in this area.
No car is without its quirks, though, and the RX 450h+ has one feature that divided opinion among my passengers. The electrically operated interior door handles replace traditional lever handles with push buttons. It is a clever idea in theory, but in practice it takes time to adjust to, particularly for first-time occupants. More than once, I found myself explaining how to exit the vehicle.
It feels like an example of technology for technology’s sake, rather than a genuine improvement in usability. Thankfully, it is a minor irritation in the grand scheme of things.
LAST WORD
By the time the RX 450h+ was collected at the start of the new year, it had woven itself very much into my daily routine. It delivered a magnificent driving experience, blending comfort, efficiency, and refinement in a way few rivals match. Compared to sportier alternatives such as the Jaguar F-Pace P400e, the Lexus prioritises serenity over sharpness, and that feels entirely appropriate for its character.
Power delivery is smooth and predictable, the hybrid system works brilliantly, and the overall ownership proposition makes a compelling case. The RX 450h+ may not be perfect, but it captures the essence of what the RX has always stood for in South Africa. Quiet excellence, delivered with confidence and class.
For those who understand that true luxury is often found in how a car makes you feel over time, rather than how it announces itself on day one, the RX 450h+ remains a deeply satisfying companion.
