Lexus RX vs Audi Q5

What's the difference?

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.

The third-generation Audi Q5 in TDI quattro form is a competent if unremarkable all-rounder that would tick most boxes for private or commercial use. Whether it’s the best buy of the 21 brands and 34 models that compete in Australia’s congested ‘Medium SUVs over $60K’ segment, only a customer can decide after weighing up its many alternatives.

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 Q5 TDI quattro rides on a 2823mm wheelbase and is 4717mm long, 1900mm wide and 1662mm tall with an 11.9-metre turning circle, so it’s a comfortable fit for metropolitan car parks. It has sophisticated five-link suspension, four-wheel disc brakes and electric power-assisted steering.

The third-generation Q5 features fresh styling with its prominent grille treatment the most noticeable feature. Overall, the standard S line exterior has an athletic look, which is optimised by our example’s larger 20-inch wheel option which nicely fills the wheel arches.

The interior has an open and airy feel, enhanced by the contrasting dark grey/pearl beige upholstery and panoramic sunroof options.

There are lots of soft-touch surfaces, exposed stitching and satin chrome highlights, plus (unfortunately) piano black surfaces on the dash and console which shine like mirrors when clean but can quickly turn opaque with unsightly fingerprints during everyday use.

Good design can be seen in the prominent ledge created by the dash inlay at the base of the central touchscreen, as you can comfortably rest the base of your palm on it to steady your index finger when using the touchscreen while driving, which is much easier and less distracting than trying to do this without such support.

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 Q5 TDI quattro weighs almost two tonnes (1955kg kerb weight) which when deducted from its 2595kg GVM rating leaves 640kg of load capacity, which for either work or play is ample for up to five adults plus luggage of which up to 75kg can be carried on the roof.

It’s also rated to tow up to 2000kg of braked trailer but Audi does not publish a maximum legal weight for the car and trailer combined (not unusual in this vehicle segment), so we can’t confirm if it can carry its full in-car load capacity when towing its maximum trailer weight.

The expansive ‘Digital Stage’ multimedia screen spans about two-thirds of the dashboard’s width, above a decent sized glove box and another compartment to the right of the driver’s knee for small items.

Driver and front passenger also have access to a bottle-holder and bin in each door plus there’s a 12V socket, two USB-C ports and a wireless phone-charging pad in the centre console, which also provides two cupholders and a storage box with padded lid that doubles as a comfortable elbow rest.

The rear bench seat offers adequate space for tall adults, given I’m 186cm and when seated behind the driver’s seat set in my position I have about 40mm of knee clearance and about the same dimension in head clearance, even with the optional sunroof.

It’s less comfortable in the centre seat obviously, with feet either side of the transmission tunnel and knees together between the front seat backrests. Shoulder room is tight for three adults, which is tolerable for short trips but a maximum of two would be ideal for longer treks.

Rear passengers get a bottle-holder in each door plus elastic net pockets on both front seat backrests. The rear centre seat backrest also folds forward to reveal two cupholders and the rear of the centre console has adjustable air vents and a pair of USB-C ports, plus third-zone climate control adjustment.

The fully carpeted rear luggage area is equipped with another 12V socket plus tidy bag, first-aid kit and four load-anchorage points. The rear section of the load floor is hinged, which when opened reveals a large underfloor storage compartment.

With the rear seat upright, this luggage area offers more than half a cubic metre of load volume. And with the seat folded flat this expands to almost 1.5 cubic metres, with a large flat floor suitable for carrying everything from a mountain bike to flat-pack furniture.

Our test vehicle is the Q5 TDI quattro which comes standard with a turbocharged 2.0-litre four-cylinder diesel engine, seven-speed automatic and all-wheel drive for a list price of $87,600.

That’s around the same spend as a Lexus NX 350H F Sport +Ep1 Hybrid AWD ($87,900) or Mazda CX-60 P50E Azami PHEV ($87,050). The NX and CX-60 are also the strongest-selling model ranges in the ‘Medium SUVs above $60K’ market segment where the Q5 competes.

The Q5 TDI quattro’s standard equipment includes 19-inch alloys with 235/60 R18 tyres but no spare (repair kit only), sporty 'S line' appearance package, matrix LED headlights with configurable signatures, LED tail-lights with dynamic indicators, an electric tailgate with gesture control (wave your foot under the rear bumper to open), heated/auto-dimming exterior mirrors and more.

The interior has power-adjustable and heated leather-appointed seating, three-zone climate control, a leather-rimmed steering wheel with paddle-shifters and multifunction controls, colour ambient lighting, matt brushed aluminium inlays, 360-degree camera view, speed sign recognition, eight-speaker audio system, inductive phone charger with adaptive cooling, combined 11.9-inch OLED driver instrument display and 14.5-inch OLED colour multimedia screen with wireless Apple/Android connectivity and more.

Our test vehicle is enhanced with numerous options including Navarra Blue metallic paint ($2000) plus the ‘Premium Package’ comprising head-up display, Bang & Olufsen 3D premium sound system, colour interior ambient lighting with dynamic interaction light, USB interfaces with higher charging capacity and acoustic glazing for the front door windows ($5400).

It’s also equipped with the ‘Style Package’ that bundles 20-inch Audi Sport alloy wheels (wearing 255/45 R20 tyres on our example) with a black exterior package and privacy glass ($4900).

On top of these extras there’s an optional panoramic sunroof with tinted glass and electric tilting/opening/retractable sunshade ($3500) plus 'natural brown walnut trunk' dash inlays ($600) and a pearl beige upholstery package which is a no-cost option (NCO).

So, when you add the combined cost of all these goodies ($16,400) our test vehicle’s list price crosses into six-figure territory at $104,000.

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).

The turbocharged 2.0-litre four-cylinder diesel engine meets tough Euro 6 emission standards using AdBlue and produces 150kW of power between 3800-4200rpm, with 400Nm of torque on tap between 1750-3250rpm.

It’s paired with Audi’s latest hybrid diesel-electric technology which can add up to 18kW of power and 230Nm of torque to these figures, while also allowing short periods of pure electric driving for low-speed manoeuvring and parking.

The seven-speed torque converter automatic offers the choice of sequential manual gear-changing using the steering wheel paddle-shifters, along with selectable drive modes to optimise Audi’s iconic ‘quattro’ all-wheel drive technology.

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.

Audi claims official combined average consumption of 5.9-6.8L/100km and the dash display was claiming 6.5 at the completion of our 364km test, which comprised our usual mix of suburban, city and highway driving with up to five adult occupants and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was 9.1L/100km which is still within the usual 2.3L/100km discrepancy between official and real-world figures. So, based on our test figure, you could expect a realistic driving range of around 700km from its 65-litre diesel tank.

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.

There’s a comfortable and spacious driving position as you’d expect, with ample seat and steering wheel adjustments combined with a large left footrest to enhance support.

It exhibits solid build quality and good driving dynamics, from its nicely weighted steering to its supple ride quality that optimises the Q5’s sprung weight to flatten the bumps.

Acceleration from the turbo-diesel engine comes in a smooth surge that benefits from the extra input of the electric hybrid system, which combined can deliver more than 600Nm of torque. However, at times we detected a slight delay in response when accelerating hard from standing starts or low speeds.

The automatic transmission shifts sweetly between its seven ratios and the all-wheel drive transmission delivers reassuring traction.

We also trialled the different drive modes, with ‘Dynamic’ providing the most energetic response, particularly when using the paddles in manual-shift mode. However, we spent most of our test in the ‘Balanced’ default setting, as it provides the best compromise between ride comfort and performance for everyday use.

Comes with a fresh five-star ANCAP rating (tested 2025) and comprehensive passive and active safety features including nine airbags, AEB, active front assist, blind-spot monitoring, exit warning, rear cross-traffic alert, front park assist, speed sign recognition, a 360-degree camera view including kerb view function and more. The rear seat has ISOFIX child seat anchorages for the two outer seating positions and top tethers for all three.

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.

The standard warranty is five years/unlimited km, which is shorter than rivals like Kia's EV5 with seven years. Scheduled servicing is every 12 months/15,000km whichever occurs first. Audi offers an upfront five-year service plan that covers the first five scheduled services up to five years/75,000km for $3520, or an average of $704 per service. This plan includes five years of roadside assistance.
