Audi R8 vs Lexus RX350

What's the difference?

The Audi R8 V10 RWD and V10 Performance Quattro have their own personalities. I'm a big fan of the lower-powered rear-wheel drive car, but the Performance is the ultimate here with better brakes and that 330km/h top speed. Either way the R8 is a true supercar, but one that doesn't have to be driven gingerly as though something may break off.

The RX is a big SUV that doesn't always look, or drive, like one, and – in 500h guise especially – can put a smile on a driver's face, too.

Gone are the cabin quirks and the polarising design elements (well, mostly...), and in their place you'll find a solid, premium-feeling family offering without much in the way of drawbacks.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

Lamborghini styling can look over the top, McLarens can sometimes appear delicate and fragile, and Ferraris seem to be everywhere, and even for me, begin to blend into one.

The R8, though, looks exactly how an Audi supercar should look – understated, tough and serious. Have you seen that Audi advert with the R8 on a dyno not wearing any pants? That sounds ridiculous but Google it because it sums up what the R8 is – a real car with a raw race car underneath, that's meant to be driven comfortably on the road and hard on a race track and the styling indicates that intent with little in the way of fanfare.

Well, there is that big window at the back which shows off the engine and the 'side blades' that surround the large vents carved into the side of the car to cool the engine.

The latest update has taken the design from the second-gen car which arrived in 2016 and added a new grille, front bumper, door sills and vents in the rear bumper. It's a more angular, sharper, and busier design with more vents and winglets than ever.

The R8 V10 RWD and R8 V10 Performance are close to identical in their styling. You can pick the Performance by its gloss carbon front spoiler, side sills, mirror caps and rear diffuser. The RWD has gloss black elements instead.

Which looks best: the Coupe or Spyder? That's a personal thing, but I reckon race cars need to have a hardtop roof, so it's the coupe for me, please.

Built using the 'Audi Space Frame' which weighs only 200kg, the R8 is 4426mm long and just 1240mm tall, but at 1940mm across it has a wide, planted stance.

Honestly, the Lexus RX looks far more powerful, and cohesive, in the metal than it does in some photos, and in the right colour (we're fond on the deep black or the copper-rose hues), it looks downright fetching.

That Predator-shaped front-end is massive, but the way the Spindle grille kind of bleeds in the body work at the nose of the vehicle is a neat trick, and the whole design ethos gives the RX a sportier, more modern, and more intimidating, energy from almost every angle.

Perhaps the most clever element though is the wave-like design piece that links the rear window with the boot, somehow managing to shrink almost-five-metre SUV (visually, at least), and leaving the RX looking more sporty than hulking.

The door handles are cool, too. They’re fixed, and you just touch them to open the door, with a similar system used once inside to get out again.

Inside, Lexus has gone for a clean, modern-feeling space, and, thankfully, there isn't a Remote Touch trackpad in sight. Instead, you can choose between two screen sizes – 9.8- or 14.0-inch – which kind of dominate the dash, while the air-con controls are digital and interactive, too.

It must be said, though, some interior treatments feel far more special than others, and while Lexus in Australia isn't spilling on specifics for our market just yet, the top-spec models will almost certainly feel more plush than the cheaper ones.

The R8 is a two-seater supercar and practicality isn't high on its 'to do' list with limited cabin storage in the form door pockets almost as small as my jeans pockets, two cupholders hiding under a trapdoor in the centre armrest, a hidey hole in front of the shifter containing a wireless charger and two USB ports and the glove box.

As for the boot – there are two: one in the nose with a 112-litre cargo capacity and another behind the mid-mounted engine with 226 litres.

Room for people, well you and a friend, is excellent. I'm 191cm (6'3") tall with a 2.0m wingspan and found the footwell deep and spacious, while head and shoulder room is also good.

The entire RX range now rides on Lexus' GA-K platform, which is lighter (-40kg), more rigid, and offers a lower centre of gravity (-15mm) than the model it replaces.

The RX is wider (+25mm to 1920mm), lower (-10mm to 1695mm), but no longer (still 4890mm) than the outgoing model. But Lexus has lengthened the wheelbase (+60mm to 2850mm) to earn some extra backseat space for rear riders.

And it must be said, there is lots of room for backseat riders. Sitting behind my own 175cm driving position I had more than enough knee room, and enough head room, and a general feeling of airy spaciousness.

Elsewhere you get the usual practicality perks, with two cupholders up front, two more in the pull-down seat divider that splits the rear seat, and there are two ISOFIX attachment points in the back seat, too.

Charging is handled by a four USB ports, and depending on the trim/spec balance Lexus in Australia shoots for, you should at least find vents with temp controls for backseat riders, too.

Lexus is yet to confirm the luggage space specs for the new RX, but given it’s only being offered with five seats, and that there’s been no change to the vehicle’s length, you can expect a fair bit of room for bags in its auto-opening boot.

This is an arbitrary seven out of 10, here. Because we don't yet know how many trim levels the new RX will launch in, how much each will cost, or what you'll get for your investment.

What we do know is that the RX will launch with three powertrain options: an all-new turbocharged hybrid, a second, more conventional hybrid, and a turbo-petrol engine. There’s a plug-in hybrid version available overseas, but we ain’t getting it. Or at least, not yet.

In terms of specific trims and equipment levels, you’ll need to wait until closer to the RX’s launch in early 2023 for the full skinny. But you can expect a choice between a 9.8-inch or 14.0-inch central touchscreen with wireless Apple CarPlay and Android Auto, an eLatch door system with fixed handles that unlatch at the push of button inside and out, as well as more high-tech safety kit (thanks to Lexus Safety System 3.0) than you can shake a radar at.

There are two grades in the Audi R8 range – the entry-point R8 V10 RWD which has rear-wheel drive (RWD), and the R8 V10 Performance Quattro which has all-wheel drive (AWD).

Both obviously have V10 engines, it's a naturally aspirated 5.2-litre petrol unit (so no turbos here), but the RWD makes less power and torque at 397kW and 540Nm, while the Performance produces 449kW and 560Nm.

The V10 is mounted behind the driver's seat but ahead of the rear axle making it mid-engined car. The engine even has its own window and you can see it in there with its face pressed up against the glass.

There are two body styles as well – the Coupe and Spyder (convertible, roadster, just another word for a retractable soft roof). We'll get to the prices in the next section, but let's talk about the more interesting numbers such as top speeds.

The V10 RWD in coupe form can reach 324km/h and the Spyder can hit 322km/h while the V10 Performance Coupe and Spyder are both a smidge quicker at 330km/h.

Those are all go-straight-to-jail speeds in Australia, so if you're tempted to fact check my numbers then do it on a racetrack. Audi holds excellent track days – I've done them and you'll not only get to drive the R8 as fast as you can, the instructors will help you improve your advanced driving skills, too. Do it, it could save your life.

Acceleration from 0-100km/h is rapid – 3.7 seconds and 3.8 seconds for the V10 RWD Coupe and Spyder respectively, while the V10 Performance Coupe and Spyder can nail it in 3.2 seconds and 3.3 seconds.

The V10 engine has a cylinder-on-demand feature which can shut down five of the cylinders while cruising on a motorway, say at 110km/h. It's a fuel-saving system, but keep in mind this V10 loves petrol and lots of it – I've hidden that all the way down the bottom of this review.

Shifting gears in all R8s is a seven-speed dual-clutch automatic transmission.

Let’s start with what we’re not getting at launch. Internationally, there's a new plug-in hybrid variant that pairs a 227kW hybrid system with a 18.1kWh lithium-ion battery for an EV driving range of more than 65kms, but fight though Lexus in Australia did, it couldn't secure the model for our market at launch. It wants it though, and badly. So watch this space. 

Instead we get three options, including the RX 350h, which pairs a 2.5-litre petrol engine with Lexus' existing hybrid system to produce a total 180kW and 316Nm. It's paired with a constantly variable transmission and will be offered in two- or all-wheel drive.

There’s also a turbocharged 2.4-litre petrol engine on offer in the RX 350, good for 205kW and 430Nm, and paired with an eight speed automatic and AWD.

But the powertrain I really, really like lives in the RX 500h F Performance, and pairs a 2.4-litre turbocharged petrol engine with an electric motor up front, and a second at the rear axle, for a total of 273kW and 551Nm.

The all-new hybrid system has been designed with turbocharged engines in mind, and features a single electric motor at the front, and a bigger rear motor, with the latter able to provide real driving power to the rear tyres - and contribute to a sprint to 100km/h of just 5.9secs.

Lexus calls it an 'eAxle' motor, and it can deliver some 76kW to the rear tyres. It pairs with a 'DIRECT4' all-wheel drive system which the brand says improves "handling, controllability, and feel."

Fitting, then, that it features on the RX 500h F Performance, which also introduces a new go-fast tier for the Lexus brand (though one you can expect to see more frequently in the near future), and which sits between the existing F Sport and the top-tier, full-fat F models.

The brand says things like bigger brakes, performance components and the highest power outputs will be reserved for the F Performance models. And so it is with the RX 500h F Performance, which welcomes six-piston front brakes, adaptive variable suspension, dynamic rear steering and 21-inch wheels.

That's like asking how many calories are in this pavlova that I'm about to push into my mouth? Seriously if you're asking then you shouldn't be eating it – or driving the R8.

But just for the record, according to Audi the RWD R8 uses 12.0L/100km in Coupe form and 12.2L/100km in Spyder guise after a combination of urban and open roads, while the AWD R8 of course will use more at 13.4L/100km for both Coupe and Spyder.

Let’s start with the pure-petrol RX 350, which will sip a claimed 8.8 litres per hundred kilometres on the combined cycle, and will demand premium petrol. The RX 350h is more fuel efficient, demanding 6.4 to 6.7 litres per hundred kilometres on the combined cycle.

But the most impressive is the RX 500h, which Lexus says will need 8.2 to 8.5 litres per hundred kilometres — making it more efficient than the petrol-powered RX 350, despite producing an extra 68 kilowatts of power and 121 newton metres of torque.

A race circuit is the best place to test the performance of an Audi R8. I've been lucky enough to have done this in the past, but for this update of the R8 the Australian launch was held on public roads and included a convoy of RS models such as the RS 6 Avant, RS 7, RS Q3 and TT RS.

Even then I think I was 'stitched up' because I began the day in the R8 V10 Performance Coupe but spent almost the entirety of my allocated time in roadworks at 40km/h before swapping to an RS Q3.

So, while I can't honesty comment about the dynamics on this updated R8 V10 Performance Coupe I can tell you that having driven every iteration of the R8 since 2012 that it's a weapon, with helicopter-like visibility out of that large front window.

If, like me, you think turbos are 'cheating' (superchargers are fine), then you'll love the linear power delivery of the R8's naturally aspirated V10, and while I love front-engined sportscars, nothing beats a mid-engined car for the feeling of balance and lightness in the nose while having the sound of thousands of explosions going off just behind your back.

Having AWD is not just great for acceleration and perfect traction from Audi's quattro system, I think it's a good safety feature in a supercar, and while only your judgements can stop things going pear shaped, the system will be there to help on slippery roads.

The following day was different. I was in the R8 V10 RWD, the country roads were superb and while it wasn't a racetrack it was enough to get a hint of the capabilities of the RWD R8.

While the R8 V10 RWD feels the same to sit in with the same great view, it feels different to drive than its faster sibling, in a good way. First there's the noticeable power difference – more than 50kW and 20Nm less – but also the lack of AWD makes the front end feel more pointable, and the car feel more like a traditional sportscar that pushes from behind rather than pulling from the front. Less power, but more fun.

The RS cars in our test convoy were all awesome machines, but stepping out of even the RS6 Avant and slipping down into the R8 cockpit was like getting into a UFO – it's so far ahead dynamically of any other Audi that all I could do was laugh like an idiot. Corners which were making an RS 7 really struggle, were handled effortlessly by the R8. And in a straight line it's a bullet in a barrel.

The Performance has the better brakes: 380mm ceramic discs with six piston calipers up front and 356mm discs with four piston calipers at the rear. The RWD has steel discs – 365mm with eight piston calipers up front and 356mm discs with four piston calipers in the rear.

Keep in mind if you are planning on track days, you'll find the ceramic discs costly to replace, and beside the stopping power of the steel ones is excellent.

And yet, on pot holed course bitumen the ride is a lot more comfortable than you might think and having driven the Performance in traffic it's a much nicer place to sit than the claustrophobic cabin of a McLaren 570S. You could honestly use the R8 daily.

Right, let’s cut to the chase here. I like the way the all-new RX family drives, pretty much across the board. If that’s all the information you want or need, feel free to check out here and move on to the next sub-heading.

Still here? Ok, then let’s go a little deeper.

None of the powertrains on offer feel under-powered in the RX range, which is a good start, but they all do their jobs a little differently. 

The RX 350 is probably the most familiar, with a traditional automatic and that well-known petrol-powered punch. It’s not the most powerful engine on offer here, but it’s more than enough to get the RX up and moving — but, for mine, it can feel a little thrashy (or like it’s straining a little too hard), when you really start to push it, but such is the price you pay for a four-cylinder engine pushing a large SUV.

Next up is the RX 350h, which Lexus reckons will be the best-selling model in Australia. Lexus and Toyota have been doing hybrid powertrains for some time now, and the system fitted to the new RX is predictably solid-feeling, though it too has its drawbacks – namely that the constantly variable transmission can drone on and on under constant acceleration, and even the commendably insulated cabin can’t block it out completely.

So if this is a Goldilocks’ scenario, then the just right has to be the RX 500h, which blends its powerful powertrain with a traditional-feeling automatic to deliver plenty of performance and a tight, engaging drive experience that makes it feel as though the big SUV is somehow shrinking around you from behind the wheel, courtesy of the best performance kit (brakes, adaptive suspension, etc).

But to be honest, no matter the RX, the thing that really stands out here is its on-road dynamics. The car doesn’t really wobble about, there’s not much in the way of body roll, and it feels tight and confidence inspiring, no matter the model - but especially the rear-wheel-steering equipped 500h.

The RX also does a commendable job of locking the outside world outside of the cabin. Where you want it to be a calm and sedate family hauler, it can be that. But it can also put a smile on your face on the right road, too.

And that, I think, is something to be celebrated. And also not something we’ve come to associate with Lexus over the years. But that’s now beginning to change. Long live F Sport Performance, then.

The Lexus RX welcomes the brand's Lexus Safety System 3.0 setup, which means more high-tech kit than you can shake a radar at.

What appears where on the Australian lineup remains to be seen, but internationally the RX will offer things like Advanced Park, remote parking from your smart phone, Safe Exit Assist that will actually prevent you opening the doors should the cameras detect pedestrians or cyclists, and Pre-Crash Safety, which scans intersections for bikes, people or cars, and activate alarms and the brakes should it sense a collision.

That, and things like Front Cross-Traffic Alert, active cruise, Lane Departure Warning and Lane Tracing Assist, road-sign recognition and Lane Change Assist, should see Lexus shooting for a five-star ANCAP safety rating.

The R8 is covered by Audi's three-year, unlimited kilometre warranty which not only falls behind in duration compared to mainstream brands but also its direct rival Mercedes-Benz which now has five-year, unlimited kilometre coverage.

Service intervals are every 12 months or 15,000km but unlike other Audi models there isn't a three-year or five-year plan available.

The Lexus family is covered by a five-year, unlimited-kilometre warranty, which is about bang-on in the premium-vehicle space. 

While servicing details are yet to be confirmed, the previous RX required a trip to the service centre every 12 months or 15,000kms, and it will fall under the brand’s capped-price servicing program, and the Lexus Encore program, which offers all sorts of perks to owners.
