Lexus RX300 vs Lexus RX

What's the difference?

The Lexus RX300 is luxurious but affordable, making it great value and superbly comfortable, with a high level of fit and finish. Fear not about the four-cylinder engine being small – it makes plenty of grunt and handles daily duties perfectly well.

Which would you go for: An entry level Lexus RX300 or a top-of-the-range Mazda CX-9? Tell us what you think in the comments below.

It’s hard to look past the value equation of the RX350h Luxury 2WD when comparing it to almost all its competitors. The pricing is on point, but there are some features missing.

However, there are very few (if any) rivals with a true hybrid powertrain (sorry, mild hybrids do not count), so the RX will capture buyers looking for environmental credentials and efficiency without going full EV.

The drive experience is much better than before and it’s all wrapped up in a very stylish package. The Lexus RX should not be ignored.

I've mentioned the Spindle grille and its jewellery-like appeal, and even the sharp edges of this SUV make the RX300 look like a carved gemstone, but I'm not the biggest fan of this vehicle's proportions. I think the door-to-window ratio is a bit off. There's just too much door for my liking.

That said, I'm intrigued by the craftmanship, the attention to detail and the use of materials, which make this SUV both pretty and intriguing.

The cabin mixes the plushness of cushioned surfaces on the dash and the armrests  with pleasing design elements, like the swooping aluminium trim, which zig-zags its way from the instrument cluster to the passenger's side of the centre console.

The giant media display is impressive, but the functionality is awkward, to say the least, but more on that in the practicality section below.

The Luxury is the entry grade into the RX model and so comes with smaller wheels than the F Sport and Sports Luxury above it, but it does score roof rails, dual chrome exhausts, a roof-top spoiler and rear privacy glass.

How big is the RX300 Luxury? The dimensions show it to be 4890mm long, 1895mm wide and 1690mm tall.

How do the looks compare with rivals such as a Jeep Grand Cherokee, a Mazda CX-9 or a Land Rover Discovery? Hmm, each has its own distinctive styling, with the Jeep having brutish American looks, the Discovery boasting prestige British off-roader personality and the Mazda an elegant air that's way beyond its price point.

So why haven't I mentioned the Mercedes-Benz GLE or BMW X5? Because they're at least $20K more than the RX300 Luxury, which costs around $72K. If, however, you can stretch the budget to an RX 350 Sports Luxury then you will be crossing the $100K threshold into Benz and Bimmer territory. So let's talk about price.

Across its five generations, the RX has held significant visual appeal - especially the still-handsome second-gen version that was the first RX sold Down Under. The first-gen model skipped Australia.

The new model that launched in 2023 is a clear evolution of the car that came before, but it’s been softened and sharpened in the right areas, giving it one of the most appealing designs in its segment.

The proportions and design elements like the squat stance, unique C-pillar treatment, slimline headlights and nicely sloping roofline give it a sporty look.

In fact, I reckon it might be the best looking Lexus available today - not including the jaw-droppingly beautiful LC coupe and convertible, of course.

The interior is modern and feels like an evolution of Lexus’ previous cabin design - but elevated. The gloss black section of the dash helps here.

Levels built into the dash break up the bulk, but the interior is very grey. It could do with a dash of colour.

The synthetic leather seat trim doesn’t look premium. If you want a more expensive feeling RX, you need to pay more for a higher grade.

The RX300 is a five-seater SUV and, while it would be even more practical if there was a third row, the cabin is impressively spacious.

Have a look at my photo of the entry to the RX300's back seat – that's a big doorway  for a car. Parents will understand the value of wide-opening doors and these ones made it easy for my child to climb into his car seat and for me to buckle him up. Head and legroom in the back seats are also good, even for me at 191cm tall, while the flat floor makes it easy to 'scoot' across from one side to the other.

There are two cupholders in the fold-down centre armrest in the back and small door pockets, but storage up front is better, with huge pull-out door pockets, two more cupholders and a large centre-console bin.

There's a wireless charger in the hidey hole in front of the shifter, plus six USB ports on board - the rear passengers have two of their own in the back of the centre console and the rest are up front.

The second row doesn't come with climate control, but the directional air vents back there got a workout over the 40C days we had over summer.

The RX300's boot has a cargo capacity of 506 litres, measured to the top of the second-row seat back.

Now,  the media system. Yes, it's a tech thing, but I'm calling out it out as impractical. The functionality of the trackpad used to navigate around the screen is frustratingly awkward. I think 12 swear words in a row came out of me on one occasion (no child on board, obviously), just trying to use the sat nav. The layout of the display menu is also confusing and non-intuitive.

The RX is a five-seat only proposition in this generation - the previous model had a seven-seat option - so if you need a third row you can look at the Lexus LM people mover or massive LX 4x4 SUV, or at any number of other three-row lux SUVs like the Volvo XC90 or new Mazda CX-90.

That doesn’t mean the cabin isn’t practical. 

Up front the seats offer excellent comfort levels and ample upper body support, but not a lot of hip support.

Lexus has changed up the door handles for the new RX and it can be complicated - initially.

The interior handles bamboozled every new person that got in my press car over the three week loan. But once you realise it’s a simple push of the thumb on the handle’s thumbpad and a gentle push, it all makes sense.

Lexus calls the electrically activated door handles an ‘e-latch’. Is it tech for tech’s sake? Probably. 

I recently reviewed the Lexus LM and commented on how much I like Lexus steering wheels and that’s true of the RX, too.

It has clearly identifiable controls and feels nice in your hands. Thankfully, the cruise control buttons are housed on the wheel too, so no annoying stalk on the wheel.

There’s plenty of space across the front row so you should avoid the awkward driver-passenger elbow bump on the centre armrest.

Under the armrest is a huge central bin that opens on the driver and passenger side. There’s also a big covered storage nook forward of the shifter and another ledge above that, as well as a sizeable glove box. 

The doors have ample storage room for bottles, but the space is almost too wide. My bottle slid around when driving so I had to lay it down.

The centre console houses two big cupholders with adjustable depth in one of them. Clever touches like this and the central bin add to the appeal.

As with the Lexus LM, I am a fan of the new Lexus multimedia set-up. It has an easy-to-navigate menu along the side, easy wireless Apple CarPlay connection, and visually appealing graphics.

It’s a world away from Lexus’ previous system. That frustrating touchpad is, thankfully, in the bin.

I quite like the gear shifter with its unusual gate and even the indicator feels and sounds premium.

Small rear windows make for a rear three quarter blind spot, but visibility is otherwise good.

On a side note, the RX has very strong air conditioning - perfect for an Australian summer.

Jumping into the second row, there’s plenty of space all around and no shortage of head, leg, knee and shoulder room. Although foot room under the front seats is tight.

As with the front seats, the rear row offers comfortable seating. Kids should be happy back there.

There’s only a small transmission tunnel so middle-seat legroom is good. And in great news for passengers, the rear backrests recline. 

Lowering the 40/20/40 split-fold rear seats for more cargo space is done via a lever on the side of the outboard seats, or by a button in the boot area. There are ISOFIX clips on the two outboard seats.

Other amenities in the second row include map pockets, two USB-C ports, knee-level air vents, climate control, and a pull-down armrest with pop-open cupholders.

Open the power tailgate and you’ll find cargo space of 612 litres with all seats in place, or 1678L with the second row stowed.

That’s a decent amount of space but not class leading. The Mercedes-Benz GLE has 630L and the VW Touareg can swallow 810L.

There’s no under-floor storage because that’s where some hybrid hardware is housed. You will find audio speakers, nice carpet, a cargo blind, two 4.0kg hooks and three top tethers. No spare, only a tyre repair kit.

The range-opening RX350h Luxury 2WD petrol-electric hybrid starts at $86,904, before on-road costs, and for that amount, the standard specification list is healthy. But it doesn’t include everything.

As well as a long list of standard safety gear (see section below), the RX350h comes with three-zone climate control, heated and eight-way adjustable power front seats, electric steering wheel adjust, rain-sensing wipers, a 14-inch multimedia set-up with wired Android Auto and wireless Apple CarPlay, digital radio, sat nav, a 12-speaker audio system, five USB-C (and one USB-A) ports and more.

It is missing a few items, however, that should be standard, such as a head-up display and wireless device charging. Those features are available as part of an options pack - or 'Enhancement Pack' in Lexus speak.

For $5000 more you get those two things and a panoramic sunroof, ventilated seats, a more digital instrument cluster and other goodies. 

You can opt for an all-wheel drive version of the 350h and that adds just over $3500 to the price. If you want the same powertrain but more gear then you’ll need to step up to the $110,575 Sports Luxury.

There’s also the petrol-only RX350 in F Sport and Sports Luxury guise, as well as the flagship RX500h F Sport Performance hybrid that tops out at $124,675.

Looking at the opening price of some of its rivals, Lexus has most of them beat.

The Mercedes-Benz GLE300d starts from $144,900, the BMW X5 xDrive30d is $134,900, Porsche Cayenne starts at $138,700 and the Volvo XC90 B5 Ultimate Bright kicks off from $100,990.

Only the Volkswagen Touareg 170TDI ($89,240) and Jaguar F-Pace P250 R-Dynamic ($83,700) are close on price.

The RX300 has a 2.0-litre four-cylinder turbo-petrol engine making 175kW and 350Nm, with a six-speed automatic transmission. This peppy four-cylinder gives the RX300 a completely different feel to the lethargic-but-powerful oomph of the RX350 and its naturally aspirated V6, even though it doesn't make a great deal more grunt, at 221kw and 370Nm. There's a difference in fuel consumption, too – find out how different below.

Is the RX300 all-wheel drive? Nope, it's a front-wheel drive. Only the RX350 and RX450h are AWD.

Powering the RX350h is a series parallel hybrid system consisting of a naturally aspirated 2.5-litre four-cylinder petrol engine, a front-mounted motor and a nickel-metal hydride battery. 

Lexus doesn’t provide combined torque outputs for the hybrid, but total power for the system is pegged at 184kW.

This drives the front wheels only via a continuously variable transmission (CVT).

Lexus says the RX300, with its 2.0-litre four-cylinder turbo-petrol engine, should use 8.1L/100km of premium unleaded after a combination of open and urban roads. My own testing over 375.4km - taking in motorways, city and suburban call-of-daycare drop-off-duties - had our RX300 using 11.79L/100km, measured at the petrol pump. The real-world results almost always exceed that of the manufacturer's claims so you can expect the V6-powered RX350, with its claimed 9.6L/100km, to have a much higher mileage again after the same kind of usage.

The official combined cycle fuel consumption figure for the RX350h 2WD is 5.0 litres per 100 kilometres, with CO2 emissions of 114g/km. You won’t get figures like that in a petrol or diesel competitor.

Over three weeks of mixed city, country, urban and freeway driving, I recorded 6.8L/100km which is not too bad given some of my spirited driving. The trip computer said 7.0L which is close to my figure.

The RX350h takes premium unleaded petrol and has a 65-litre fuel tank, so expect a range of around 950km based on our real-world consumption number.

Good seats are the start of a good driving experience and I've not met a Lexus that doesn't have superb pews – from the uber luxury models, such as the LS500 and ES300, to sports cars such as the RCF or LC500, they all have supportive and comfy ones. Lexus somehow manages to  combine the comfort of a lounge chair yet still holds you firmly, all while placing you in a great driving position. The RX300 is no different. Large enough to fit me and my 191cm frame, yet bolstered enough to feel snug.

As for performance, the RX300, with its four-cylinder turbo-petrol engine with its six-speed automatic, is responsive and a bit hyperactive feeling. It's a very different sensation to piloting the RX350, which has a V6 and delivers its grunt in a more linear and lethargic fashion. Having driven both back-to-back I'd say the V6 and its eight-speed auto suits the RX personality better, but the 300 is a car that would have had a school report card that read: "Lots of potential, but lazy".

That said, plant the right foot and the RX350 will get the message to hurry up and can do the 0-100km/h sprint in eight seconds flat. The RX300 is keen but can't match it, with  a time of 9.2 seconds.

Either way, the ride comfort is excellent, although body control could be better - the speed bump and roundabout route I take to do the preschool drop off caused it to  get the wobbles, but give the RX300 a motorway and it'll cruise beautifully.

Forward visibility is good but vision through the tiny rear-quarter window (it's even smaller than it looks) while reverse parking isn't great.

The old RX was competent and even nice to drive but not a patch on the likes of the BMW X5. The new-gen RX improves on that in a big way.

It offers solid acceleration from a standing start. Lexus says 8.1sec from 0-100km/h - without giving you chills. The sportiest RX is the 500h Performance hybrid and that covers the same distance in 6.2sec.

The transition from electric power to petrol propulsion is more evident in this model than it was in the LM350h people mover I tested recently - the RX is a little noisier. The CVT doesn’t help this, offering up an uninspiring engine note.

It is, however, a much more fun car to push into tight bends than the previous RX. It remains reasonably flat in corners, and pulls out of tem with ease, but can’t compare to the dynamics of the dearly departed IS sedan.

The 19-inch tyres have large sidewalls and as a result soak up harsh bumps on the road. The non-adaptive suspension is tuned for better dynamism, meaning the ride quality is on the firm side.

The front-wheel drive RX lost traction for a second on a sweeping uphill section of my drive route, but the electronic traction systems otherwise kept the big SUV in check. 

But around town in urban areas, there is very little to complain about behind the wheel of the RX350h.

The RX comes packed with standard safety gear and the SUV was awarded a maximum five-star crash safety rating from ANCAP in 2022.

Just some of the inclusions are auto emergency braking with pedestrian (day/night), cyclist (day/night) and motorcyclist (day) detection, intersection assist, emergency steering assist, driver monitoring, lane keeping aid and lane departure warning, adaptive cruise control, front and rear parking sensors, blind spot monitor (including stationary) with rear cross-traffic alert and safe exit assist to avoid 'dooring' incidents. 

I must say, Lexus’ (and parent company Toyota’s) driver assistance tech has come a long way.

In the early days of the pandemic during a rare non-lockdown period in Melbourne, I drove from Melbourne to Sydney in the previous-generation Lexus RX200 Sports Luxury.

The lane keeping system and adaptive cruise control were shockingly underdone. The cruise control would simply stop working when you encountered even a slight downhill section. 

Not anymore. The new, smoother lane keeping set-up uses subtle wheel adjustments, unlike the ping pong effect of the previous RX, and the cruise system is now very much in control of the speed.

The Lexus safety suite now operates without too much intervention and is hard to beat among its key rivals.

Lexus recommends servicing the RX300 annually or every 15,000km, with the first three services capped at $595.

The duration of Lexus's factory warranty is four years/100,000km, which is a bit longer than BMW and Benz's coverage, but behind the five-year/unlimited-kilometre warranties of the mainstream brands.

The RX350h is covered by a five-year, unlimited-kilometre warranty, and the servicing schedule is every 12 months or 15,000km.

There’s a capped-price servicing plan lasting five years and it will cost $695 per service. That's significantly less than some rivals like the Mercedes GLE.

The RX is covered by the 'Lexus Encore' loyalty program and includes complimentary service loan cars, fuel offers as well as discounts and other offers with Lexus partners.
