Audi S3 vs Lexus RX500H

What's the difference?

There are plenty of historical instances where a particular model within a broader range manages to hit the absolute sweet spot even though it’s not the fastest or most expensive variant. Porsche’s GTS specification across various models is a great example of this.

And at the risk of being proven wrong when the all-new RS3 comes along later this year, this car, the S3, might just pull off that feat.

Yes, the new RS3 will be more powerful and will offer even more grip and sporty flavour, but it will also be more expensive. And we defy anybody to drive the S3 and say that it lacks dynamism in any single area.

It’s also a magnificently balanced car with the right amount of attention paid to every aspect of its trim and performance. That, in essence, is where that `balanced’ label originates and even though it’s felt most in the actual driving experience, it permeates throughout the entire vehicle.

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.

Perhaps the most striking thing about the styling of the new Audi is just how similar it looks to the old model. Okay, this is not a new thing with Audi which has made a point of not throwing a handsome design into the dumpster in pursuit of new for new’s sake.

As such, the exterior lines are taut and typically Audi clean and, with the latest LED headlights and a refinement of the Audi trapezoidal grille, the look is fresh and crisp without being a novelty act.

Inside, the virtual dash display and large, relatively flat centre console almost amount to anti-styling. Or it would if the rest of the deal wasn’t so sharply angled towards a philosophy of less is more.

Again, this is classic modern-era Audi where the game is to make a complex layout look as simple as possible. The face-level air vents also seem to have borrowed a little Lamborghini (part of the Audi family) DNA.

I particularly like the new shift-by-wire gear selector which is a nifty looking switch but works just as intuitively as a conventional shift lever. New tech meets old muscle memory, I’m calling it.

It's worth mentioning (again) just how good Audi’s customisable dashboard display is. With sharp, clear graphics and the ability for the driver to prioritise the information on display at the time, the S3’s display is still about the best in the business.

Overall, ergonomics have always been a long-suit of this brand and there’s been a clear intention to follow that tradition this time around.

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 SUV owners are often quick to tell you that they bought their car for its interior space, the truth is sometimes different. And without the huge wheel-wells and suspension towers of a high-riding SUV, the conventional hatch or sedan often has an advantage.

Certainly, there’s no lack of room in the S3 and the hatchback version has a wide hatch opening to make loading easier. The sedan, however, is a full 150mm longer than the hatch and that extra is all behind the rear seat.

So the boot is actually very useable with a capacity of 325 litres. Audi claims the same 325 litres for the Sportback, but that figure jumps to 1145 litres with the rear seat folded flat.

The rear seat in either variant is handily split 40/20/40 and there are storage nets on the back of each front seat, luggage nets in the cargo area and 12-volt outlets in both the centre-rear and luggage compartment. Even floor mats are standard.

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 a lot of the extra currency demanded for the S3 goes. Forget the 1.5-litre engine in the base-model A3, and instead move to the two-litre four-cylinder as seen in the A4 40 TFSI. Then, add extra turbo-boost (up to 1.8 bar thanks to an efficient intercooler) different variable valve timing protocols, and a direct fuel-injection system with a specific calibration and the potential to create injector pressures of up to 350 bar, and you have the S3’s powerplant.

Maximum power is 228kW at anywhere from 5450 to 6500rpm, and maximum torque of 400Nm produced in a broad range between 2000 and 5450rpm.

Transmission is a seven-speed dual-clutch unit driving through all four wheels as per Audi’s Quattro mantra, although it’s important to note this version of Quattro is the simpler, arguably less pure, on-demand system where the car behaves as a front-drive platform until the all-wheel-drive system is required to step in.

That said, with 228kW under its wheels, that’s a fair bit of the time. And compared with previous systems, this one takes more notice of driver inputs and wheel-speed to be less reactive and more active.

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.

Audi quotes an official combined cycle fuel consumption figure of 7.4L/100km for the A3 Sportback and 7.3 litres for the sedan.

That difference is a bit of a mystery given the sedan is heavier (by just five kilograms) until you consider that the combined figure includes freeway running, at which point the sedan’s extra 150mm of length and different rear diffuser may be the aerodynamic deal-breaker.

The Sportback emits 170 grams of CO2 per kilometre (166 for the sedan) and with the 55-litre tank fitted, both variants should have a range of around 750km between fill-ups.

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.

Some cars take a few minutes at the wheel before they start to get chatty. Not so the S3. From the moment you grab the lovely leather tiller, haul it into gear and give the perky little turbo-motor a squeeze on the throttle, the Audi is making all the right noises and giving clear, precise feedback on its every move.

Sometimes, cars with lots of tyre, lots of all-wheel drive grip and the sort of sharp steering fitted here, can start to feed back so many responses that it becomes difficult to know which one to respond to.

Not the S3, which seems tuned to a keener driver’s priorities (as it should be, of course). As a result, the steering feedback is distinct from what the rest of the front end is doing and everything else going on is clear, quantifiable and designed to improve the experience.

That even extends to the soundtrack which, Audi told us does not use any electronics to improve it beyond amplifying the engine-bay harmonics which use the windscreen and scuttle as their 'speaker.'

Combined with the active exhaust system, this car honestly sounds like a five-cylinder engine (I opened the bonnet to count the spark plugs to make sure it wasn’t. It isn’t.)

If you’ve ever driven a five-cylinder Audi or a V10-powered R8 (two in-line fives, really) the tune will be a familiar one. Lovely, and – again - such amazing attention to detail.

The 2.0-litre engine runs fairly high boost levels, but that doesn’t seem to have affected the way it storms off the mark. Neither does the dual-clutch transmission contribute any delay, provided you haven’t managed to stand on the brake and throttle at the same time (as many left-foot brakers might).

At that point, the driveline goes into sulk mode and will force you to wait a heartbeat or two before full power is restored. This can be an issue when trying to dart across a busy intersection or merge into a traffic flow.

It’s not a new thing to Audis, but remains an annoyance to those of us who equate having two pedals with having two feet.

The driver-selectable drive modes fitted to the S3 are interesting inasmuch as they actually make a meaningful difference to the way the car operates. They alter the transmission shift points, the throttle sensitivity, steering weight and damper settings.

'Comfort' mode will be the default for most owners, and while 'Dynamic' does sharpen up the dampers ever-so-slightly beyond an acceptable day-to-day level of firmness, it also adds weight to the steering feedback.

Frankly, I don’t think it needs it and simply adding resistance feels like a token gesture. And since the steering has a (non-negotiable) variable rate in the first place, bigger inputs equal a bigger proportionate change of direction anyway.

The damping control is now the more sophisticated magnetic-hydraulic type where hydraulic pressure varies the valving rather than the simpler, previous system of energising an electro-magnet to alter the viscosity of the damping fluid.

This more finite control system has allowed more 'bandwidth' as Audi puts it, between Comfort and Dynamic damper settings.

While the auto mode is almost prescient, it’s not actually pre-emptive but rather takes into account suspension deflection, wheel-speed and driver inputs to come up with a combination of settings to make the most of the situation.

And if you really want to fiddle, you can choose 'Individual' and create an overall setting that combines bits of Comfort and Dynamic with a smattering of 'Efficiency' thrown in.

Toggle down to Dynamic and throw the S3 at some bends and it soon emerges as a pretty gripped-up piece of equipment. The front-drive bias is not really noticeable, but then neither is the transition where the computer begins to engage the rear multi-plate clutch to turn the rear axle into an active participant.

There’s certainly no lack of grip at any stage of a typical corner, and even the odd unexpected damp patch poses no awkward questions. Perhaps the biggest grumble would be the tyre roar at highway speeds, but that’s often the price of performance rubber.

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 has finally had to cave in and extend its warranty to match its competition. So, any new Audi sold after January 1 this year moves up to a five-year/unlimited kilometre factory warranty; a big step up from the previous three years of cover.

S3 buyers can also opt for Audi’s five-year service plan which costs $2580. Servicing is set down for every 15,000km 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.
