Audi Q5 vs Lexus RX

What's the difference?

It might be a late return to the PHEV game for Audi, but it’s an impressive one. Everything great about the Q5 remains - dynamically engaging, responsive powertrain - but you get the added benefit of electric power.

This could be the car to prove that plug-in hybrid medium SUVs don’t have to be bland family transport. If the Q5 is anything to go by, going green can be downright fun!

So, is the latest Lexus RX good enough to stay, or should it sashay away?

In almost every single way except accessibility (the cheapest is now $15K more expensive, remember), the newcomer is hugely better than the model it replaces, with a level of sophistication and refinement – as well as comfort – that the underwhelming predecessors just could not manage.

And, yes, while there is tech shared with the Toyota Kluger (as there's always been), RX #5 looks, feels and drives much more like a large luxury SUV should.

Speaking of which, few rivals can match the family-friendly RX's combination of customer service, glamour and opulence.

Our verdict then? This Lexus has gone from being a drag to one of the queens of the BMW X5 class. RX... Shantay, you stay!

The second-generation Q5 has been around for six years, and it was very much an evolution of the original, but it still looks attractive in the metal. You couldn’t call it edgy, but it is handsome.

Both PHEV body styles get the S line exterior package as standard, which adds a unique honeycomb grille, S line bumpers front and rear, Audi Sport wheels and it borrows the rear spoiler from the SQ5.

While many will favour the swoopy Sportback body style, I think the Q5 is at its most arresting in SUV body style, bathed in the gorgeous 'District Green Metallic' paint. Stunning.

Inside, only the Sportback gains the S line interior, which includes a leather three-spoke steering wheel with multifunction, shift paddles and hands-on detection, Nappa leather upholstery with contrast stitching, and aluminium inlays. The SUV seats are leather-appointed. 

It’s fair to say Audi’s interiors have modernised since the launch of this Q5 in 2017, but it’s still hard to fault. The multimedia screen jutting out the top of the dash is a little old school these days, but the materials and quality are top notch.

They used to say that the revolution will not be televised.

At first glance, the same also applies with this fifth-gen RX, since all the big changes are largely out of view.

Precisely how different it looks depends on which angle you're looking at it from.

Observing nose-on, the RX's front tracks and body are wider and it boasts a new Spindle Body grille design which is meant to have a 3D effect, but is quite fussy to some eyes. And this is meant to carry on through to all future Lexuses, by the way.

Yet, in profile, the newcomer is hard to distinguish from the old one, with its returning floating roof C-pillar motif, which looks quite sleek. Yet the wheelbase has been stretched, which results in 60mm more interior space, and that benefits overall proportions as well as occupants.

Some reckon the strip tail-light design and clean surfacing make the rear the RX's most arresting angle.

Note that Lexus has dropped the old RXL seven-seater model – it didn't sell very well. A replacement is coming but it won't be anything like the new RX. Stay tuned to CarsGuide for more on that in the not-too-distant future!

As - predominantly - a family hauler, the Q5 has always done well in the practicality stakes. And adding a plug-in hybrid powertrain hasn’t changed that. Although you do lose some boot space compared with the petrol models - but more on that in a bit.

Up front, the Q5 has plenty of nooks and storage slots in the console, including a longer shallow slot to hold phones. The central bin is deep enough and the door bins can swallow big bottles and more. Housing the phone charger on the top of another storage spot in the console works as it can be hidden by the larger storage lid for security.

As the Q5 is older than some of Audi’s fresher models, there are physical buttons for things like air conditioning, seat heaters, and controls for drive modes and other vehicle functions.

It might not look as schmick as having a screen to house everything, but from a practicality and safety perspective, it’s welcome.

This approach also extends to the multimedia system which is fairly simple to navigate with a logical menu. Audi’s system gets a tick, as does the digital cockpit - something the brand pioneered.

While the leather appointed seats in the SUV are nice, the quilted Nappa leather seats in the Sportback are much more luxurious. And the ‘Rotor Grey’ colour scheme is simply beautiful. They offer more than enough support in the front row and they are comfy without being super plush.

There’s ample leg and headroom in the front row.

That is the same for the second row. So much headroom even with a panoramic sunroof. And behind my 183cm (six foot) driving position, there was room to spare in front of my knees. It’s such a good size.

Also, the rear seats have some bucketing so passengers will feel a little spoiled. There’s also knee-level air vents, map pockets, two USBs and a 12-volt port, a fold-down armrest with cupholders and ISOFIX points on the outboard seats.

The rear row folds 60/40 and there’s decent room in the boot, which has a power operated tailgate. 

Given some of the PHEV hardware sits directly under the boot floor, it’s little surprise that the SUV version (465 litres) loses 55L of space compared with the petrol-powered 45 TFSI.

Similarly, the Sportback (455L) drops by 45L. Also, despite the swoopy roofline, the Sportback only loses 10L of cargo space compared with the more practical looking SUV.

Those PHEV bits also mean there is no spare wheel - only a tyre repair kit.

At nearly 4.9 metres, the RX is deceptively long, and that pays dividends inside, while a larger and roomier cabin are the main beneficiaries of that stretched wheelbase.

Step inside, and you're greeted by a modern, attractive and functional dashboard that looks and feels upmarket – even in the least expensive version. This isn't always the case with luxury SUVs. You're not aware of corners being cut or cheap materials. It all seems really well crafted.

Sumptuous front seats provide loads of squishy, cushy comfort as well as adjustability to help find the right driving position for you. Taller people can now sit lower down if they like, meaning it's less cramped for them now. In fact, most occupants will find the RX pretty spacious up front.

Lexus has also worked hard to right other previous wrongs as well.

While not especially pretty or distinctive, the instruments are clear and informative, providing a wide array of driving, vehicle and multimedia data as required. That old intimidating tech-overkill presentation has been binned. Mercifully.

For example, the central touchscreen now features shortcuts for the most often-used items, so you're not forever diving into menus and sub-menus for climate control, navigation, audio, vehicle settings or phone access. And there's now a 'Hey, Lexus' voice control function to further aid useability.

Other plus points up front in the latest RX include an excellent audio system, extremely effective yet unobtrusive ventilation, and loads of storage – whether in the decently sized glovebox, beneath the vast centre armrest or within the deep door pockets.

And while they might need a moment to get used to, the e-latch electric door handles soon become second-nature to operate. And they provide a potentially life-saving extra bonus.

Speaking of which, there's even more surprise and delight to help you connect with the RX emotionally. It isn't all about wearing sensible shoes in here.

For instance, the big 14.0-inch touchscreen looks and feels contemporary yet is wonderfully user-friendly. It actually invites you to play around with it. The dashboard's horizontal themes create a sense of width and space that's... freeing. There are far fewer buttons than before, down from 81 to 50, though they're also still around for vital functions like audio volume control. And on some grades, the varying ambient lighting choices include exhilarating, relaxing and arousing.

But while this interior is a huge step forward and one of the most appealing aspects of this latest RX, there are some misfires remaining.

Chief among them is the infuriating cruise control buttons with their new-fangled 'capacitive touch' tech, which is fiddly to use and alarmingly distracting. This is a throwback to the infernal mousepad controller found in older models.

The same applies to the camera-based rear-vision mirror found on higher grades, which can induce nausea at a single glance. Did Lexus actually test this on humans beforehand?

Moving to the rear seat, it's clear the company did put the family first, with that stretched wheelbase and extra legroom it liberates. Your 178cm tester found ample headroom, legroom and kneeroom sat behind a front seat set up for them. Meanwhile, the cushion is well padded and the (reclinable) backrest comfy.

Amenities include face-level air vents, climate controls, USB ports, a centre folding armrest with cupholders and storage, overhead lighting and grab handles, deep door pockets and a decent view out.

Overall, that premium feeling up front continues out back too.

And great news for family car buyers – the latest RX's has a larger boot, it now measures in at 612 litres (and expands to 1678L with the rear seats folded down), and comes with a long, flat floor with some storage underneath.

Note, though, that only the F Sport has a temporary spare wheel – the rest make do with a tyre repair kit.

Like everything in life these days, it costs more to get into an RX.

In fact, some $15,000 more, because the old 2.0-litre four-cylinder turbo-petrol RX300 is gone, replaced by the new RX350h hybrid as the new base entry-level model.

But Lexus says there's more than enough extra features to offset the price hikes.

As before, there are three established grade levels available: Luxury, Sport Luxury and F Sport.

Exclusive to the 350h, the base Luxury 2WD kicks off from $87,500 (all prices are before on-road costs). It mates a 2.5-litre four-cylinder petrol engine with an electric motor and battery pack, that drive the front wheels. A second electric motor on the back axle turns it into AWD for $4500 more. That's known as the e-Four system.

The Luxury is far from basic. Standard features include LED headlights, three-zone climate control, electric and heated front seats, keyless entry and start, electric door handles, synthetic leather trim, a 14.0-inch touchscreen with sat-nav, DAB+ digital radio, Android Auto, wireless Apple CarPlay, 12-speaker audio, 'Hey, Lexus' voice control, six USB ports, 40:20:40 split rear seats with auto fold, electrically adjustable steering column, a powered tailgate, roof rails and 19-inch alloy wheels.

There's also plenty of advanced safety kit. Check out the safety section for more details.

Next up is Sports Luxury, available on the 350 (which basically swaps out the hybrid tech for a 2.4L turbo) from $105,900 and 350h hybrid from $111,900.

Keep in mind that, from here on in, every RX comes with AWD.

Sports Luxury equals plush, since it ushers in goodies like bi-LED three-projector headlights with auto high beams and washers, 360-degree surround view monitor, variable suspension damping for a comfier ride, a heated steering wheel, a head-up display, heated/vented front seats, slicker leather, extra fancy front seats, 21-speaker premium audio, wireless smartphone charger, power reclining/folding rear seats with heating/ventilation, rear sunshades, ambient lighting and 21-inch alloys. Active Noise Control is also featured on the RX350.

If you want your RX to be a bit sportier, then there's the F Sport in 350 turbo guise from $99,900; it adds uprated brakes, kick sensors for that powered tailgate and more, but loses the Sport Luxury's power folding/heated/vented rear seat, heated wheel and a few other minor items.

There's also an 500h F Sport Performance. From $126,000, this is the RX range-topper for now. Based on the 350 F Sport, it adds a hybrid setup with two electric motors to the 2.4L turbo – a first for any Lexus or Toyota in Australia, as well as rear-wheel steering and an artificial exhaust note piped through the sound system.

Finally, on the base Luxury, Lexus bundles desirable features like leather, a sunroof, vented front seats with driver's side memory, easy-access entry, a head-up display, fancier digital instrumentation and wireless phone charger in an Enhancement Pack.

Starting from $5100, it's like upgrading from Business to First Class travel. There are other option-pack bundles across the range as well.

So, is the new RX good value for money? Undercutting most rivals while not scrimping on features, it's hard to argue otherwise.

The Q5 pairs a 2.0-litre four-cylinder turbo-petrol engine - found in many VW Group products - with a plug-in hybrid set-up that includes a lithium-ion battery pack and an electric motor.

The total system output is 270kW of power and 500Nm of torque, which is impressive. In fact, it has more power - but a little less torque - than the SQ5 performance flagship. 

It drives all four wheels thanks to Audi’s quattro all-wheel drive system, and does that via a seven-speed dual-clutch automatic.

As per the Toyota RAV4 hybrid, the RX350h uses a 2487cc 2.5-litre four-cylinder petrol engine producing 140kW of power at 5200rpm and 239Nm of torque from 4300-4500rpm.

Combined with a 134kW/270Nm synchronous permanent magnet electric motor and nickel-metal hydride battery, it drives the front wheels via a continuously variable transmission (CVT). Maximum system power is 184kW.

The sprightlier E-Four option adds a second electric motor on the back axle to provide AWD. It betters the 2WD's zero to 100km/h sprint time of 8.1 seconds by 0.2s.

Next up is the RX350, which swaps out the hybrid tech for a 2393cc 2.4-litre turbo unit, pumping out 205kW at 6000rpm and 430Nm from a low 1700-3600rpm, while driving all four wheels via an eight-speed torque-converter auto. Its 0-100km/h time is 7.6s.

Finally, there's the RX500h hybrid, combining the 350's 2.4L turbo (producing 202kW at 6000rpm and 460Nm from 4300-4500rpm) with two electric motors (one on each axle) and a unique six-speed auto, for a combined 273kW. It's rapid too, reaching 100 in just 6.2s.

Oh, by the end of 2023, the RX450h+ plug-in hybrid electric vehicle (PHEV) will also be part of the line-up.

On all models, suspension is the tried-and-tested MacPherson-style struts up front and a multi-link rear arrangement. The RX's platform is new, sharing the TNGA Toyota New Global Architecture with the Camry, RAV4, smaller NX and – you've guessed it – the latest Kluger.

The PHEV’s battery capacity is 17.9kWh and that ensures the Q5 has an electric driving range of up to 55 kilometres on the WLTP protocol. 

Audi says the average daily commute of an Australian is 35km, so technically many people could get to work and back using electric power only.

It might not sound like a huge amount, but it’s more than the 41km offered by the BMW X3, although it doesn’t come near the Lexus NX’s 87km claim.

Energy consumption is rated at 23.9kWh/100km, and the official fuel consumption figure for the Q5 is 2.0 litres per 100km - bettering the X3’s 3.2L/100km figure but not as frugal as the Lexus (1.3L).

It has a 54-litre fuel tank and emits 45 grams per kilometre of CO2.

The Q5 PHEV has a Type 2 plug and comes with a charger to add more juice at home.

It has an AC charging capacity of 7.2kW and it will take two and a half hours to fully charge using a home wallbox charger. You can also plug it into a regular wall socket at home and it’ll be charged up in about eight hours, or overnight. It's not capable of DC charging.

No shocks here.

The RX350 turbo slurped 11.0L/100km over our launch drive route, which took in both peak-hour traffic jams and rural highway runs, compared to 9.6L for the 500h hybrid turbo and just 6.4L for the 350h hybrid.

So, how do these compare to the official figures?

Well, quoting the pretty-lax NEDC numbers, the 350 should average 8.7L, the 500h a frankly surprising 6.5L while the 350h shines at just 5.0L in the 2WD and 5.4L for the AWD version.

The corresponding carbon dioxide ratings are 114g/km (RX350h 2WD), 123g/km (350h AWD), 197g/km (350 turbo) and 148g/km (500h).

Technically, then, the most economical RX, the 350h 2WD, can average 1300km per (65L) tank! The 350h AWD can achieve about 1200km, the 500h about 1000km and the 350 turbo just 776km (using a bigger 67.5L tank).

Both RX hybrids can drive silently in electric-only mode stepping off the line, at low speeds or when coasting along, and that's really impressive. Less so is every RX's thirst for more-expensive 95 RON premium unleaded petrol.

The Q5 has always been the driver’s pick among its peers - specifically the BMW X3 and Mercedes-Benz GLC. You could argue a Porsche Macan is more engaging and you’d probably be right. But of those immediate German rivals, the Q5 takes the cake.

Adding a PHEV powertrain and the circa-300kg of extra weight that brings should impact dynamics - but somehow, it doesn’t. 

First of all, the Q5 PHEV can do the 0-100km/h dash in just 5.3 seconds which is hot hatch territory. 

But the really impressive thing about this Q5 is how well it handles, despite that extra weight. The battery pack is housed under the boot floor, and Audi engineers have done a bang up job in ensuring it retains that dynamic prowess it's known for. 

We drove on some delightfully twisty roads in the Gold Coast hinterland for this launch event, and the Q5 didn’t miss a beat.

It maintained composure when pushed into tight corners, and had plenty of grip. And the electric urge coming out of those corners - providing you have battery charge left - only helps the experience.

Typically sharp Audi steering is indeed present and welcome.

Riding on 20-inch Audi Sport alloy wheels, and with a sporty bent, you’d think the ride quality would be impacted. But that was another pleasant surprise.

The Q5 soaks up corrugations with the standard suspension set-up, and the tyres have a decent sidewall. So no unpleasant sharp bumps detected.

The cabin is reasonably well insulated from most outside intrusion as well.

If you've owned any previous-generation RX, you'll definitely recognise most if not all of their good points, like ease, smooth-road and low-speed refinement, and complete reliability and dependability.

But now the Lexus has gained a far, far broader range of talents and capabilities. And that's a direct result of the series switching to the TNGA platform, like most of its brethren (and Toyota cousins).

Let's begin with the most exciting edition, the flagship RX500h F Sport Performance.

This is the brand's first hybrid turbo, and it's a cracker. Electrified for silky quietness when stepping off the line, the internal combustion engine (ICE) takes over seamlessly as soon as you need to really get moving, providing a rich, torquey shove as required.

While not BMW X5M fast, it's rapid all right, and satisfyingly responsive to your right foot. The whoosh is accompanied by an artificial (albeit quite nice) exhaust note, that's a bit turbine-like, to let you know you are or are about to break the law speeding.

Additionally, wearing 21-inch wheels and tyres, there's an exceptional amount of road grip, for safe, planted handling and roadholding. This applies to all the latest RXs, actually. But – and despite its 100-150kg weight penalty compared to lesser versions ­– the 500h feels the most athletic. Basically, it does what the tin says it should.

The flipside? While the adaptive dampers do smooth out most bumps, it can get a little jittery over some surfaces. And it is prone to some tyre noise intrusion over some bitumen. Yet, compared to former big-wheeled RX, the 500h's ride is comfy enough.

Next up is the RX350. This is basically the 500h with the same four-pot turbo engine but minus the electric motors and battery, so it benefits from a 155kg mass saving. And that's immediately obvious in its better high-speed agility.

However, while the engine loves a rev, the lack of electrification and all that meaty torque it brings is always noticeable, meaning the driver has to always mash the accelerator for overtaking to be over quickly. And as a result, the 350 can sound a bit noisy. Otherwise, for normal commuting and point-to-point travel, this is fine. Unremarkable but supremely capable. You'll miss the hybrid oomph, though. And the economy.

Finally, there's the RX most people buy – the 350h. Yes, there's a RAV4 engine and motor(s) stuffed in haute couture, but this is so much more than that. Performance from a standing start is always brisk, with speed piling on with delightful ease if you so desire, and there always seems to be some muscle left in reserve for instant manoeuvres – whether going fast or slow.

The whole experience is seamless, easy and muted. Only when you floor the throttle does the powertrain whine, but it's not that sort of SUV.

Plus, wearing the 21-inch wheels and with the adaptive dampers, the 350h steers, corners and rides well enough, being both skilful and accomplished, if not especially involving, let alone thrilling.

What we're saying is that the base hybrid proposition is good enough to wear the Lexus badge. The RX has finally come of age, dynamically speaking. And about time.

At the time of publishing, there's wasn't an ANCAP crash-test rating for the latest Lexus RX. But the old one tested back in 2015 managed the full five-star result.

We're expecting a similar outcome, especially due to the RX's stiffer, stronger and lighter body, along with a slew of fresh safety related features.

These include better autonomous emergency braking (AEB) performance, with improved pedestrian and cyclist detection, avoidance braking, lane-keep assist, blind-spot monitoring and adaptive cruise-control capability technologies. The latter now features full-stop/start and low-speed following ability – great for slow traffic jams.

Note there is no data on AEB operating parameters at the time of writing. 

Also present are auto high beams, road sign recognition, front/rear cross-traffic alert, reverse parking cameras, all-round parking sensors, tyre pressure monitors and 'Safe Exit Assist' – which won't allow doors to open if passing cyclists or pedestrians are in danger of being struck.

There's also 'Intersection Turn Assist' (providing early brake activation if required), 'Emergency Steering Assist' (extra steering assistance to help keep the vehicle in its lane) and 'Emergency Driving Stop System' as standard across the range – along with a digital rear-view mirror on some grades.

You will also find eight airbags (providing coverage to all outboard occupants, also taking in dual-front occupant knees and a centre item to stop lateral head strikes), as well as Lexus Connected Services with – among other features – an SOS button or automatic emergency services notification with vehicle co-ordinates should the driver be incapacitated following an accident.

Finally, anti-lock brakes with brake-assist and electronic brake-force distribution is also standard, along with stability and traction control systems. Lexus provides three rear-seat child-seat tether anchorages and two ISOFIX latches.

The Q5 comes with Audi’s five-year/unlimited kilometre warranty. This was an increase on its previous term that Audi announced at the start of 2022. The PHEV is also covered by an eight-year/160,00km battery warranty.

Service intervals are every 12 months or 15,000km, whichever comes first, and Audi offers a capped-price service plan for five years that costs about $3500 all up. That’s a little pricer than BMW and Volvo’s plan.

Lexus now offers a five-year, unlimited kilometre warranty with roadside assistance.

Furthermore, hybrid versions of the RX include a 10-year, unlimited kilometre battery warranty.

Service intervals are at 12 months or 15,000km, whichever comes first.

The RX offers three years and 45,000km of capped-price servicing, with each one costing owners $695 – that's pretty competitive for a luxury brand.

So is the first-rate ownership experience. Amongst other benefits, there's Lexus' 'Encore' aftersales subscription program; free for the first three years, it includes myriad offers and services including discounted petrol.

Plus, owners can have their cars picked up remotely and returned washed, and with free use of a loan vehicle delivered to their door.
