Audi S3 vs Lexus RC350

What's the difference?

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

If you’re a buyer that thinks with their head, the RC 350 F Sport is the obvious choice when compared to its direct rivals.

After all, it looks great (at least to these eyes), feels luxurious in more ways than one, and is unrivalled when considering value-for-money.

But, if you think with your heart instead, it’s clear it is isn’t on the same level dynamically and therefore doesn’t feel as sporty to drive as its name suggests.

So, don’t let its sports car classification fool you, the RC 350 F Sport is more of a grand tourer, or a comfortable cruiser, to be precise, and an underrated one at that.

The S3 Sportback may be a small car, but its S design features, like the stylised blackout grille, matrix LED headlights, and 19-inch alloys with red brake calipers, give it a distinctly athletic and fun-loving vibe. It’s compact, but definitely not diminutive and carries serious road presence. It’s hot hatch meets fun-size.

Inside, the S3 looks fabulous. Integrated ambient lighting, a sharp dashboard treatment and a driver-focused cockpit all lend it a premium feel.

The front seats look properly sporty with their integrated headrests, and the quilted Nappa leather upholstery feels great, especially with the eye-catching red contrast stitching.

As for technology, it’s as high-end as you’d expect with a 10.1-inch touchscreen multimedia display and 12.3-inch digital instrument cluster taking centre stage.

The only drawback? No sunroof. Combined with the black headliner and compact cabin, it can feel a little gloomy at times. Still, it’s a cabin you’ll enjoy spending time in.

Looking at the RC 350 F Sport, it’s hard to imagine how it became so anonymous on the road, whether you love it or hate it.

Up front, its striking design simply cannot be ignored, with its unique mesh 'Spindle' grille insert demanding attention.

Either side of it are the LED headlights and boomerang-style daytime running lights, which, again, cannot be missed.

Around the side, the RC 350 F Sport has all the hallmarks of a classic coupe, including a swoopy roofline, and looks all the better for it.

The 19-inch alloy wheels wrapped in a mixed set of Bridgestone Potenza tyres are particularly arresting thanks to their sporty 10-spoke design.

That said, the rear end is arguably the RC 350 F Sport’s best angle, at least universally, thanks to its crisp LED tail-lights and chunky bootlid.

The bumper below is also a looker, even with its fake side air intakes, while its diffuser insert is flanked by a pair of chrome exhaust tailpipes.

Inside, the RC 350 F Sport isn’t quite as good, with most of our criticism directed at the 10.3-inch central display, which is powered by an average multimedia system made worse by an incredibly fiddly touchpad controller. The physical shortcut buttons on hand are but small mercies.

Thankfully, Apple CarPlay and Android Auto support is now standard, so a better user interface is literally in your pocket… but you still don’t have a touchscreen to work with.

The RC 350 F Sport’s button-controlled 8.0-inch digital instrument cluster is much better, even if it’s more like a multi-function display due to its limited functionality.

While the centre stack and console designs are undoubtedly showing their age, there’s no doubting this is a premium model thanks to the selection of high-quality materials used throughout the cabin.

In our test vehicle, black leather-accented upholstery with (very cool) 'Tuscan Sun' yellow accents, piping and stitching covers the sports steering wheel, gear selector, sports seats, armrests, door inserts, knee rests and the instrument cluster. So, almost every touch-point.

Pleasingly, soft-touch plastics are used for the upper and middle dashboard as well as the door shoulders, with hard plastics only found on the lower dashboard, door bins and rear seat divider.

As per other Lexus models, the RC 350 F Sport has nice rose-gold accents on its steering wheel, gear selector, front air vents and centre console, while specific Naguri aluminium trim adorns its dashboard and door inserts. And there are also steel pedals.

Like most hatches, the front row enjoys the most space. While it’s cosy, it never feels cramped. The seats are firm yet comfortable, thanks to their adjustability and expandable under-thigh supports. Access is fairly easy with wide door apertures, though the low seating position might earn a few grunts, especially from taller folks.

Storage up front is well sorted, with a glove box, a small centre console, a dedicated phone cradle and a couple of cup and bottle holders. It’s about what you'd expect for a car this size, but it's enough to keep things tidy.

There are plenty of charging options, with two USB-C ports in each row and a wireless charging pad up front.

The multimedia system is intuitive and easy to use. The touchscreen is responsive, and wireless Apple CarPlay connected without fuss and stayed connected all week. Wireless Android Auto is available, too.

Built-in sat nav is clear, and I love the way directions pull through to the digital instrument panel. The Sonos sound system? Pretty darn good. My son and I had more than one mini-concert on the school run.

As for the rear row, it definitely reminds you this is a small car. At 168cm, I found it on the cramped side of cosy and my husband just laughed when I asked him to try it! The wheel arch also cuts into the door aperture, making access a little awkward. Best to think of it as occasional adult seating. But given the size, that’s no surprise.

Amenities in the back are decent with a couple of map pockets, cup and bottle holders, as well as a fold-down armrest, those USB ports and rear temperature control (but curiously, no fan control). The seats are comfortable enough, but space is limited. Realistically, it’s best suited for two passengers, not three.

Boot space is quite practical. The wide opening and manageable load lip height make it easy to slide items in and out. It offers 325L of space, less than its key rivals, but expands to 1145L with the rear seats folded flat. The handy 40/20/40 split also adds versatility. Under the boot floor, you’ll find a tyre repair kit.

Hope you’re not expecting the RC350 F Sport to be the first word in practicality, because it’s not.

Measuring 4700mm long (with a 2730mm wheelbase), 1840mm wide and 1395mm tall, the RC350 F Sport is a decently sized coupe, but that doesn’t mean it’s spacious. Hell, it’s hard to get into it the first place, let alone out.

We are of course referencing the token second row, which is cramped at best. In fact, behind my 184cm (6.0ft) driving position, there is no toe-room nor headroom. Yep, if you’re around my height or taller, get used to burying your chin into your chest.

Thankfully, legroom is better but still limited to less than two centimetres, while foot space is compromised by the unusually tall transmission tunnel. And in case you were wondering, even the first row is on the tighter side.

Beyond the central air vents, you’d think rear occupants would be cheered up with cupholders, a fold-down armrest and USB ports at the very least. Well, they don’t get any of that, with a couple of coat hooks the only amenities on offer.

And don’t forget that being a four-seater, there are only two seats in the second row, so this is definitely not a ‘family car.' That said, there are two ISOFIX and two top-tether anchorage points for child seats, so you can theoretically take a couple of younglings with you on a trip.

In-cabin storage options are very limited, with the glove box small in size and mostly taken up by the manual, while the central bin is useable but somewhat occupied by two USB-A ports, a 12V power outlet, and an auxiliary input.

And whatever you do, only bring up to two drinks with you, as beside the pair of cupholders next to the gear selector, there is no other place to officially store extras. Yep, the front door bins are only good for storing very short and narrow items.

The boot is a different story, with a decent 374L of cargo capacity, and it can be expanded by stowing the 60/40 split-fold rear bench, an action that can annoyingly only be performed in-cabin via the manual release latches.

That said, the boot’s tall load lip makes unloading bulkier items a little trickier, while getting them onboard in the first place is complicated by its wide but short aperture. At least there are four tie-down points on hand to secure loose loads?

Priced from $78,636 plus on-road costs, the RC 350 F Sport commands $3000 and $8000 premiums over its lower-output RC300 and lower-spec Luxury siblings.

In terms of rivals, the RC 350 F Sport significantly undercuts the best-selling Mercedes-Benz C 300 Coupe ($89,000) but is about on par with the Audi A5 40 TFSI Sport Coupe ($78,900).

Standard equipment not already mentioned in the RC 350 F Sport includes rain-sensing wipers, power-folding side mirrors, satellite navigation with live traffic, digital radio, an 835W Mark Levinson sound system (with 17 speakers), keyless entry and start, dual-zone climate control, power-adjustable front seats with heating and cooling, a power-adjustable steering column and an auto-dimming rearview mirror.

Yep, it’s loaded, which is very good news. What isn’t, though, is its foot-operated park brake. Sure, the RC is six years old, but electric park brakes were well and truly a thing in 2014, so it’s quite an annoying quirk.

The RC 350 F Sport only has two options: a $2500 power-operated sunroof and $1500 premium paintwork, both of which were fitted to our test vehicle, with the latter taking the form of 'Graphite Black.'

The S3 Sportback wears the quattro badge proudly, meaning it’s all-wheel drive and it pairs a tweaked seven-speed automatic transmission with a 2.0-litre turbocharged, four-cylinder petrol engine.

This update brings a bump in performance over the previous model, including the addition of a rear torque splitter. Power is now up to a gutsy 245kW and 420Nm of torque, launching the S3 from 0 - 100km/h in just 4.7 seconds. That’s proper hot hatch territory.

The RC 350 is motivated by a lusty 3.5-litre naturally aspirated V6 petrol engine that produces 232kW of power at 6600rpm and 380Nm of torque from 4800-4900rpm.

For reference, the RC 300 uses a 2.0-litre turbo-petrol four-cylinder unit that develops 180kW at 5800rpm and 350Nm from 1650-4400rpm.

Either way, these outputs are exclusively sent to the rear wheels via a well-sorted eight-speed torque converter automatic transmission with paddle-shifters.

This combination helps the RC350 sprint from a standstill to 100km/h in about 6.1 seconds while on the way to its electronically limited top speed of 230km/h.

The S3 Sportback has an official combined fuel consumption figure of 7.9L/100km and a 55-litre fuel tank, giving it a theoretical driving range of up to 696km.

Its key rivals hover around similar numbers, so it's right on the mark for the segment. After a mix of long-distance drives and my usual urban errands, my real-world figure came in at 8.0L/100km - very close to the claim, which I’m pretty happy with.

The RC350’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.1 litres per 100 kilometres, while its carbon-dioxide emissions are 212 grams per kilometre, but both claims are a little keen.

In our real-world testing, we averaged 12.2L/100km, which is far cry from the above, given our result came from 180km of driving that was heavily skewed towards highway stints over city traffic.

For reference, the RC 350’s 66L fuel tank takes 95 RON premium petrol at minimum.

The S3 Sportback sounds as mean as it looks, and it delivers on that promise with effortless grunt. Acceleration is immediate, with plenty of power on tap when you need it. It’s just fun all around.

The lowered sports suspension and wide tyres do bring some extra noise into the cabin, even at lower speeds. You might find yourself repeating things to rear passengers now and then, but it never feels overwhelming.

Steering and suspension are on the firmer side, so yes, you’ll feel the bumps but the payoff is sharp, responsive handling. Quick lane changes and winding coastal roads are where this car shines.

Visibility is about what you’d expect from a low-slung hot hatch. The pillars don’t obstruct the view, but sitting beside a towering SUV at the lights can make you feel a bit... compact.

Cornering is a strong suit, thanks to the car’s wide stance and AWD system. It feels confidently planted in most conditions. That said, I noticed the occasional wobble through the rear frame on rough sections in heavy rain.

Its compact size makes parking a breeze, especially with the help of multiple sensors. The reversing camera is crisp, but at this price point, the lack of a 360-degree camera view feels like a missed opportunity.

The RC350 F Sport is actually pretty good to drive – so long as you understand what it’s about.

Think of it more as a comfortable cruiser than a sports car and you’ll forgive it for some of its shortcomings. Yep, it is that relaxing to drive.

While the F Sport’s suspension (independent double-wishbone front and multi-link rear axles with adaptive dampers) does have a sports tune, it still serves up a comfortable ride on most surfaces.

Naturally you can play with the five drive modes (Eco, Normal, S, S+ and Custom) on hand to increase its stiffness and therefore improve handling, but the difference between soft and ‘hard’ is negligible, so don’t bother.

Either way, the F Sport does have a noticeable habit of picking up sharper road edges, such as nasty potholes, and it's particularly prevalent at the rear. That said, it doesn’t detract from its luxuriousness all that much.

Where the sportiness really comes to the fore, though, is via the F Sport’s electric power steering system, which has a variable ratio.

As well-weighted as this set-up is as standard, you’ll find it hard to forget how sharp it is on turn-in. Among several factors at play, the obvious one is the F Sport’s rear-wheel steering system, which is better executed than most.

This technology turns the front wheels in the opposite direction to the rears at lower speeds but in the same orientation at higher velocities.

The result of the former? A mid-size coupe that feels like it has a short wheelbase, with the improved manoeuvrability especially noticeable in car parks. Conversely, the latter lends itself to greater stability when you need it.

And it’s a good thing it is the way it is, because the RC 350 F Sport has a kerb weight of 1740kg, which is not exactly sports-car light. This heft is a felt when cornering hard, even though body control is pretty strong overall.

Handling performance is also enhanced by the rear Torsen limited-slip differential, which helps improve grip upon corner exit, at which point the RC 350 gets to show off its straight-line abilities.

The V6 engine is buttery-smooth, but you really need to stick the boot in to fully enjoy it, with it only really starting to come alive when engine speeds are above 3000rpm.

That said, it’s easy to appreciate this character trait around town, where the RC 350 is truly unfazed. Take it onto the open road, though, and acceleration is more than pleasing.

The automatic transmission is a great dancing partner here, serving up delightfully smooth gear changes. It’s also surprisingly responsive, perhaps too responsive, as it can be quite fussy in city traffic, shuffling up and down ratios in quick succession.

Biggest gripe, however, is the digitally enhanced sound the RC 350 produces. Sitting inside, the noise being pumped in is satisfying, but you can’t help but acknowledge the aural deception at play.

Neither ANCAP nor Euro NCAP have issued a safety rating for the RC range, although the mechanically related IS line-up received the maximum five stars in 2016.

Advanced driver-assist systems in the RC 350 include autonomous emergency braking (with pedestrian detection), lane-keep assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, a (low-resolution) reversing camera and front and rear parking sensors. Yep, the only major thing missing here is steering assist.

Other standard safety equipment includes eight airbags (dual front, side, curtain and knee), anti-lock brakes (ABS), electronic brakeforce distribution (EBD), brake assist (BA) and the usual electronic stability and traction control systems.

Audi backs the S3 Sportback with a five-year/unlimited kilometre warranty, which is on par with its European rivals. A five-year pre-paid servicing plan is available for $2890 which is cheaper than pay-as-you-go and reasonable for the class.

For those looking to go the extra mile, the 'Audi Advantage' package lets you extend the warranty and capped-price servicing by an additional two years, which represents solid value overall.

Servicing intervals are every 12 months or 15,000km, whichever comes first.

As with all Lexus models in Australia, the RC 350 comes with a four-year/100,000km warranty and four years of roadside assistance. Both offers are a year behind that of fellow premium brands Mercedes-Benz and Genesis.

The RC 350’s service intervals are every 12 months or 15,000km, whichever comes first. A three-year/45,000km capped-price servicing plan is available, costing $495 per visit, which is not too bad at all.
