Audi Q5 vs Lexus RX500H

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.

The Lexus RX500h F Sport Performance certainly gave a solid driving performance this week. I was comfortable behind the wheel and enjoyed the luxe features up front. I feel that it's missing some luxe items in the back seat and some of the family storage options that other large SUVs can have but otherwise, it suited my family’s needs. The fuel efficiency was quite surprising for a hybrid, so this gets a 7.0/10 from me.

My son really liked the panoramic roof and his high seating position. So, he gives this an 8.0/10.

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.

The RX is a deceptively large SUV, at first glance the sporty tailoring might make you think it’s the smaller NX sibling but park it and you’ll see how it fills up a space!

It’s 4890mm long and 1920mm wide but the compact 1695mm height is what causes the misdirection.

Let’s get straight into some of the obvious design changes. The iconic ‘spindle’ grille design has been flattened at the top with a new body panel. It’s a design choice that makes the bonnet look more bulbous than sporty but that’s pretty much all I don’t like.  

It was a great choice to lift and level out the sloping of the bonnet because it looks a lot more purposeful now. There’s lots of sporty elements too with the black 21-inch alloy wheels and faux-mesh intake vents at the front and rear. Plus, I’ve always been a fan of the floating roof effect that’s created by the black panelling that shoots from the C-pillar to the rear.

It’s not just the exterior that’s been revamped. The interior now boasts a massive 14-inch touchscreen multimedia system, up from the 12.3-inch screen from the previous generation. The gear shifter is now an e-shifter and the dashboard has been ‘stepped’ to make it feel like you’re being tucked into the cockpit. There’s new ambient lighting inside too, designed to make the interior feel like a luxury lounge.

All round, they’ve nailed the ‘luxury’ aspect.

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.

Sometimes you can forget how many luxury items this car has because they've been sprinkled around too sparsely.

For example, front passengers definitely enjoy the most this car has to offer. The legroom and headroom are both great, while the luxe factors feature heavily with the heated and ventilated seats and heated steering wheel. It’s great that there is dual-climate control up front and ample individual storage on offer.

The driver has a lot of technology within easy reach – the 14-inch touchscreen multimedia system is simple to use and has built-in satellite navigation. You can pull the directions into the head-up display and there’s still a healthy mix of physical dials on display. The wireless Apple CarPlay was easy to connect to and there’s also wired Android Auto, Bluetooth connectivity and digital radio (which was good in the city, terrible in regional areas).

Front passengers are absolutely spoiled when it comes to charging options, too. You can choose between an USB-A port, three USB-C ports, 12-volt port and a wireless charging pad!

When I reviewed the smaller NX sibling, I struggled with the e-latch door handles but finally got used to them on this model (I even like them!). My six-year-old found them to be frustrating at times and if the groans from my family members are to be believed, they weren’t impressed either but I do think it came down to it being a ‘user’ issue!

The backseat is comfortable and perfect for my 168cm height but taller passengers may feel a little cosier. The seats are set in a stadium setting, which does make you feel like you’re teetering in corners but my son loved the high position.

You can comfortably fit a couple of child seats back there but it might be a squeeze for three. The wide door apertures do make it easy to fit a child seat and to bend down to buckle them in.

Individual storage is limited to just map pockets, two cupholders and skinny drink bottle holders in the doors. The amenities never quite make it to luxurious either but I did like seeing two USB-C ports and retractable sun blinds.

The boot space is decently sized at 612L but the aperture is sloped, which means you might struggle to fit some bulky items. It has a level load space and it’s easy to access the temporary spare tyre. The powered tailgate with kick-function is super quick and handy too. 

There are six models for the RX and the 500h Sport Performance completely replaces the previous 450h model as ‘top dog’.

As with most things, the purchase price has shifted upwards with a hearty $126,000 tag (before on-road costs). However, it’s still almost $10K more affordable than its nearest rival, with the X5 at $139,900 and the GLE at $135,200 (all before on-road costs).

Being a top model means you enjoy the perks of many features coming as standard, like electric front seats with lumbar support, heated and ventilated front seats, heated steering wheel, panoramic sunroof and leather accented seats and trim.

It even has real aluminium inserts for the accents and a new for 2023 digital rear-view mirror.

The only luxe factor that it doesn’t have, but should for a flagship model, are heated and ventilated outboard seats in the back row.

Other features include some decent tech, like wireless Apple CarPlay and wired Android Auto, three-zone climate control and a premium Mark Levinson sound system but more on that below.  

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.

There is only one engine for the top model and that’s a 2.4-litre, four-cylinder turbo-petrol hybrid offering. It has a combined max power output of 273kW.

This replaces the old V6 hybrid engine from previous models but I found it to still be punchy. In fact, it’s claimed that you can do 0-100km/h in as little as 6.2 seconds.

It’s an all-wheel-drive and features a cool – eAxle … meaning the car is a bit clever with its power distribution using the electric motor to power the rear axle and the petrol engine to power the front. You can notice the gear changes with the six-speed auto transmission but overall, this combination delivers a solid performance.

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 fuel figure is 6.5L/100km and that’s up by half a litre on the previous model. Real-world testing saw my figure at 8.3L, and I was disappointed with the efficiency. There are more efficient options out there that I would consider if the ‘hybrid’ part of the model’s name was what interested you.

With the 65L fuel tank and based off the official combined figure, you should be able to get a 1000km driving range … but based off my experience, I would expect a little less than that.

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.

My first thought when I drove this was that it doesn’t drive like a big car. It has nice sporty handling – it feels firmly positioned on the road and the steering is responsive.

There’s a definite sense of power but it’s lazy. You have to get firm with the accelerator but it performs well when you push it.

There’s an interesting duality at play here because, despite this, it’s not sluggish - I’m just as confident on the open-road as I am zipping across traffic in this.

The suspension is adaptive and feels springy. It handles cornering quite well but I’m not as firmly seated as I would like. My husband said the same from the passenger side.

The cabin is extremely quiet and peaceful until my kid gets into the car. Then it’s 20-questions in 20-seconds. But otherwise, the new active noise cancelling this model has, works.

I really love the 11m turning circle – parking this in a rat-warren car park was simple. The 360-degree view camera is easily in my top three for camera tech that I’ve used and I like how the car ‘disappears’ when you’re manoeuvring. It makes it easier to navigate a tight spot and not get distracted. Large SUVs can sometimes feel daunting to park but not this one.

The RX has a full suite of safety features that are always great to see on a large SUV, like: LED daytime running lights, lane keeping aid, lane departure alert, blind spot monitoring, rear cross-traffic alert, 360-degree view camera, front and rear parking sensors and dynamic parking guidance.

A cool highlight is the 'Safe Exit Assist' which will alert you via the dash if the car has sensed an oncoming obstacle when you go to exit the car. However, Lexus goes further and if the obstacle is still present and you try to open the door, the car will LOCK your door and stop you from exiting. Pretty neat!

The autonomous emergency braking with forward collision warning has car, pedestrian and cyclist detection (operational from 5.0 – 80km/h and up to 180km/h for car detection).

It achieved a maximum five-star ANCAP safety rating from testing done in 2022. However, this model used to have 10 airbags but now only has eight. I do like that it now has the front centre airbag.

There are ISOFIX child seat mounts on the outboard seats and three top-tether anchor points. You may get lucky with three skinny child seats but two will fit best. A 0-4 rearward facing child seat can be installed but will encroach on front passenger comfort, especially if they’re tall.

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 ownership terms have been improved too with the RX now coming with a five-year/unlimited km warranty term, which is more in line with the market standard.

It has a five-year/75,000km capped-price servicing plan and services cost $695, which is $100 more than the previous model. Even with the price hike, the servicing costs aren’t as expensive as others in the class. 

Servicing intervals are reasonable at every 12 months or 15,000km – whichever occurs first, which is good.

Lexus recommends a minimum of 95 RON petrol for this model.
