Audi Q5 vs Lexus RX350H

What's the difference?

The new Q5 does a lot right even if it doesn’t feel as resolved from behind the wheel as I had expected.

It catapults one of the oldest premium SUV nameplates into this decade, and all three of its launch powertrain options are great, so you can’t really go wrong.

Each features the smoothness and efficiency of genuine hybrids backed by punchy turbo combustion thrills, while the increase in standard kit across the entire range is notable at a very reasonable price increase.

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.

Proportionally, the new Q5 is quite a departure from its curvaceous predecessors, thanks to a more chiseled bodyline and stronger flares over its wheelarches. While this makes it the biggest stylistic departure for the Q5 ever, embracing its all-new PPC (Premium Platform Combustion) underpinnings, its stylistic motifs are still somehow very familiar.

The traditional Audi grille is maintained, although has been modernised with a geometric pattern and integrated highlight pieces depending on styling package, and even the light profiles manage to be somewhat familiar despite their twinkly new customisable LED elements and contemporary slimline appearance.

A closer look only makes the car feel more contemporary, with strong contours around its face and bumpers, which were absent from its more plain-looking predecessors.

In addition, the brand tells us the Australian market in particular has one of the highest levels of uptake of large wheels, so it offers a range of designs to choose from on the options list, many of which are on the larger side, despite the standard wheel being 19 inches.

The interior is where the biggest changes are. While Audi interiors have been familiar for the longest time, the new Q5’s interior appointments feel dropped directly out of its Q6 e-tron electric alternative.

The result is a completely re-thought approach to the interior design, which is now dominated by huge touchscreens as well as a collection of contemporary shapes and mouldings that transport the Q5 into the current decade.

Still, elements of familiarity are present. The seats feel like Audi seats, the materials are as you’d expect for the brand and the wheel is backed by familiar switchgear.

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.

While the interior might feel as modern as they come, it also brings with it some of the pitfalls of contemporary design themes.

The most obvious is the over-reliance on touch panels for controls. The most egregious example is the lack of physical buttons for the climate control, which is interacted with via a permanent part of the touchscreen, but it doesn’t end there.

On top of this, there are capacitive gloss finish panels for the steering wheel controls, and even a capacitive panel in the door to control the mirrors and lights. It all looks swish, but isn’t the best to use compared to just… buttons.

Apple CarPlay worked flawlessly in my time with various versions of the car, and the stock software is fast and crisp. Interestingly the digital instrument cluster is the most plain version of Audi’s usually stellar virtual instruments yet. Without the big animated cluster dials it used to have it feels a bit less fun to look at.

Adjustability and space is great for front passengers, as is the amount of visibility on offer, plus the seats are as comfortable as ever in all grades.

Storage is ample in the cabin, with big bottle holders in the centre console, large pockets in each door, and a halfway decent centre console. The phone charger sits tucked away at the front with the USB-C outlets and a volume dial.

The back seat is less impressive. The Q5 never had the most spacious second row in this mid-sized segment, but it’s disappointing to see this new-generation car hardly improves on the formula. It’s spacious enough for me at 182cm tall behind my own driving position, with enough room for my knees and airspace for my head, but it’s certainly not as spacious as many rivals. In addition, the centre position is compromised by a huge rise in the floor, making it a hard pitch for an adult to sit there.

On the plus side, there’s plenty of amenities with bottle holders in each door, a further two in the drop-down armrest, netted pockets on the backs of the front seats, and an entire third rear climate zone with touch panel temperature control and physical air vents. There’s also two USB-C outlets.

One trade-off for the small second row is a large boot. It measures 520 litres with five seats up, or 1473L with the second row down. It also comes with a few neat things like a net and sliding cover.

Unfortunately, while there’s a small amount of underfloor storage, there’s no spare wheel, with Audi only offering a tyre repair kit.

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.

Here’s where things get interesting. Despite featuring three carryover engine options, the Q5’s big upgrade is the introduction of a hybrid system.

The brand calls this technology MHEV+, which I think is underselling what the system can actually do. Normally a mild hybrid (MHEV) system consists of higher-voltage electrics to assist auxiliary systems and take a small amount of load off the engine, or provide a more robust stop/start system, but this new Audi tech consists of an 18kW/230Nm electric motor placed after the seven-speed transmission that can motivate the entire vehicle under electric power for small periods. It can recapture up to 25kW of energy and is supported by a 1.7kWh battery pack.

The three engine options supported by this include the base TFSI 2.0-litre four-cylinder turbo front-wheel drive (150kW/340Nm), the mid-spec TDI 2.0-litre four-cylinder turbo diesel (150kW/400Nm) exclusively in all-wheel drive, or the SQ5’s 3.0-litre turbo-petrol V6 (270kW/550Nm).

There’s no disappointments here. All powertrains feel up to the task, and for those of you waiting for an all-wheel drive base petrol or a plug-in hybrid, the brand assures us both are on the way soon.

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).

All engine options are also relatively efficient, although the total fuel reduction from the introduction of this new MHEV+ hybrid technology is surprisingly small. Audi says it saves up to 0.74L/100km and 17g/100km of C02, which doesn’t sound like a lot for a system that can pull the whole car.

Regardless, fuel consumption is 5.7L/100km for the TFSI 2.0L FWD petrol, 5.4L/100km for the TDI 2.0L AWD diesel, or 7.6L/100km for the 3.0-litre petrol V6 SQ5. The emissions are also relatively low for a premium SUV.

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.

To drive the Q5 is familiar in some ways and less familiar in others. The initial impression is good, with each variant being relatively quiet on the road, offering a nice adjustability and driving position, with great visibility around the car.

The new powertrain options are all a joy to pilot, with all feeling punchy and smooth-shifting through the seven-speed auto. This smoothness is helped along by the introduction of the new MHEV+ tech, which can push the car along at reasonable speeds without needing the engine to assist.

It might not be quite as punchy as some other hybrid systems in terms of overall assist, but it’s certainly better than other systems we’ve seen on the market that barely help with driving or smoothness, and end up being a cynical emissions-saving device. It’s nice to see this tech is a step forward for the brand.

The familiar Q5 driving points are mostly intact, too, with the most notable upgrade being the ride comfort. This car is much more adept at dealing with road imperfections than its predecessor, with a softer suspension response.

This having been said, I expected more from this ground-up new platform. Each version of this Q5 I sampled felt less dynamically engaging than its predecessor. The usually sharp Audi steering tune feels a bit disconnected in this new car, with a little bit too much electrical and software assist, and the suspension, while more comfortable, isn’t as engaging in the corners.

It, too, lends the car a disconnected feeling over undulations and corrugations, giving the new Q5 an overall less resolved feeling from behind the wheel than I would have liked. The previous car was a bit sharp, but at least it was consistent in the way it responded to the road.

The previous car started to feel old towards the end of its run. Previous Audi owners will enjoy how this new car catapults the nameplate into this decade in terms of its cabin ambiance and general demeanour, it would have just been nice to see the consistency return, too.

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.

Audi continues to offer its fairly standard five-year and unlimited kilometre warranty with five years of roadside assist and this is paired with the option of a five-year service plan.

This costs an additional $3520 ($704 per year) for the 2.0-litre variants, or $3560 ($712 per year) for the 3.0-litre V6-powered SQ5. Servicing is required every 1500km or 12 months.

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.
