Audi RS4 vs Renault Duster

What's the difference?

What a way to send off this generation of Audi RS4 and RS5. The extra focus courtesy of those trick coil overs and drama from the exhaust plus the sharper gear changes deliver the best Audi has done with these RS products. 

There are some compromises, with the suspension favouring outright control over low-speed comfort. It’s also true that the current BMW’s M3 and M4 are more impressive, but when the products are nearly seven years fresher than Audi’s, what do you expect? 

Plus, those looking for a more restrained and polite fast executive sedan (or wagon) will gel with the Audi’s sophistication. There aren’t many of these Competition Plus RS4 and RS5s coming to Australia and they are impressive visually and from behind the wheel. It’s a fitting way to send off the current generations.

The Renault Duster 4x4 Evolution (manual) is a driver’s car. Lots of fun for day-to-day duties and a real visceral experience if you like to have a few laughs on loose-dirt and gravel tracks. And it’s adequately capable for off-roading adventures. It also has more than its fair share of cheeky charm.

Obviously it’s not anywhere near the most capable off-road vehicle available. That’s not what it’s intended to be. But it’s one of the most fun to drive on- and off-road.

And for $36,490 (excluding on-road costs), you’ll still have cash enough for a set of all-terrain tyres and some accessories.

The RS4 Avant’s 'Progressive Red' metallic helps the black milled 20-inch alloy wheels pop. Its stance is hugely purposeful with wheels tucked right up in the blistered arches courtesy of the lowered ride height — it's how the Avant would have looked in a design sketch.

The visual bulk of the long-roofed RS4 gives it the sort of proportions motoring journalists love to wax lyrical about, even if plenty of buyers still prefer coupes or lifted SUVs. 

The RS5's more flowing, elegant lines match well with the Navarra Blue paint work, silver-accented wheels and conventional leather-appointed seats within. 

Both cars have effectively identical front cabins reflecting Audi’s classy and sleek design language. The integration of technology is pretty good and the RS4’s additional red styling pack really makes it feel sporty within.

From the outside, the Duster 4x4 Evolution has that special ‘something’ that draws your eye. It’s unassuming, yet somehow eye-catching.

It’s a chunky little AWD with ‘Renault’ across the front grille and its raised stance gives the Duster a rugged presence.

Hard angles and nifty touches, such as the concealed rear door handles on the C-pillar, add to its funky exterior.

The Duster’s interior continues the minimalist theme with hard plastic surfaces everywhere – including the dash and door armrests – and black and grey cloth upholstery, all amid a neat but uncluttered layout.

The 10.1-inch multimedia touchscreen , angled slightly towards the driver, dominates up front and caps off what is an unpretentious, functional cabin.

The RS4's cabin is excellent, with a good mix of physical buttons and responsive touchscreens for control. There’s enough storage space for this kind of vehicle, with good door bins and well-sized cupholders in the centre as well as USB-C and -A charge points. 

Audi’s multimedia system is friendly though the large touch targets and dark background aren’t as crisp as those fitted to the latest rivals. The screen isn't as big, either, measuring 10.1 inches for the multimedia item. The RS4 supports wireless Apple CarPlay and Android Auto.

That said, Audi’s 12.3-inch digital driver’s display with bright and poppy mapping software and generous customisation remains right at the head of the pack. 

There is a panel of switches below the touchscreen for climate control, physical selection of the five-or-so drive modes and a collection of helpful buttons on the perfectly-shaped and sized leather-appointed steering wheel.

It lacks F1 or DTM wow-factor compared to the C63 and M3 with their easy-access driver mode buttons and toggles on the steering wheel but the RS4's restrained looks will resonate with those that prefer a bit more elegance inside. 

Neither the RS4 nor RS5's back seats are designed for those over about 175cm. The RS4’s roof is a little higher so it is good enough for most adults but the RS5’s sloping profile compromises things. It has two individual buckets compared to the RS4’s three-wide bench. 

Rear seat passengers get air vents, an individual climate zone, bottle holders in the doors, USB charge points and ISOFIX attachments for the outboard seats, with matching top tethers in the seat backs.

The Audi RS4’s boot is a generous 505L with under floor storage and a netted area on the driver’s side. Folding the 40/20/40 split-fold bench increases space to 1495L. That said, the RS5’s 465L is still very good, though it is not quite as practical in the real world. 

Being fitted with roof rails makes for sleek integration of roof racks for the RS4 to slip roof pods, bike racks or whatever else you might choose to take on a trip away.

The interior in Evolution trim matches the Duster’s no-nonsense adventure-focussed approach. It’s spartan but user-friendly.

The front seats are manually adjustable and the cloth upholstery looks like it’s hard-wearing and likely able to cope with the utter messiness of life.

I had trouble getting my phone to work via the 10.1-inch multimedia unit, but otherwise I have few complaints about the system as it’s easy enough to operate. There’s a wireless-charging pad below the screen. There are also two USB-C charging ports up front and two for rear-seat passengers, as well as two 12-volt sockets one in the front and another in the rear cargo area.

There is a mix of physical buttons and on-screen controls to operate various in-cabin functions, such as air-con.

For storage there is a glove box, a deep centre console, two cupholders, and a small shelf for your pocket clutter.

The second-row seats are roomy enough for two adults or three teens across the row and while passengers there have access to two USB-C charging ports and air vents, there’s no fold-down centre armrest.

The rear cargo area is accessed via a manual tailgate and is claimed to offer 358 litres of cargo volume when the rear seat is in use and 1424 litres when the second-row seat is stowed away.

Payload in the Duster Evolution 4x4 is listed as 503kg. The cargo area has a light, cargo hooks and a 12V socket. This Duster has a 215/70 R16 spare stored underfloor.

The 2026 Renault Duster is available as a 4x2 (automatic) or 4x4 (with a six-speed manual) in two trim levels – the Evolution and the Techno – with a choice of a turbocharged 1.3-litre four-cylinder engine (for the 4x2) or a turbocharged 1.2-litre mild-hybrid three-cylinder engine (for the 4x4).

Our test vehicle, the 4x4 Evolution, has a manufacturer suggested retail price of $36,490, excluding on-road costs.

Standard features include a 10.1-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a wireless smartphone charger, 7.0-inch digital instrument cluster, six-speaker Arkamys sound system, dual-zone climate control, 17-inch alloy wheels, Continental Cross Contact 215/65 R17 tyres and a 215/70 R16 spare.

There’s also a range of accessories available including Rhino Rack and Thule storage platforms and racks.

Exterior paint choices include the no extra cost 'Solid White' as well as 'Khaki Green', 'Pearlescent Black', 'Terracotta', 'Cedar Green', 'Sandstone' and 'Shadow Grey'. All metallic or premium paint adds $750 to the Duster’s price.

Audi’s 2.9-litre twin-turbo petrol V6 has seen plenty of use across performance products from Audi and Porsche, including the Macan S and Audi S6. 

In the RS4 and RS5 Competition Plus, it develops the same 331kW (at 5700-6700rpm) and 600Nm (at 1900-5000rpm) as the regular car. This makes it an extremely flexible engine that delivers predictable punch anywhere in the power band.

That said, it lacks the explosive character of BMW’s twin-turbo inline six — the figures are only 15kW and 50Nm higher on paper yet the M3’s response is that much more ferocious. 

Audi’s RS division has tried to capture a bit more emotion, retuning the eight-speed torque converter automatic transmission for crisper shifts. This also benefits the RS4’s 0-100km/h sprint time, which falls two tenths to 3.9 seconds in Competition Plus guise. 

The V6 breathes a little easier, too, with a different exhaust. Audi says the extra sound is down to 8.0kg less sound deadening in the car.

There’s more resonance at idle that does feel tiring sitting in traffic idling but the trade-off is a brawny mid-range baritone that develops into a shrill bark approaching the redline.

The Duster 4x4 Evolution has a 1.2-litre three-cylinder turbo-petrol engine with a 48V mild-hybrid system (producing 96kW at 4500rpm and 230Nm at 2250rpm) matched to a six-speed manual gearbox.

As I said earlier, a new small 4x4 SUV with off-road capability and a manual gearbox is refreshing.

This Duster has an all-wheel drive system and the little 1422kg SUV can do the 0-100km/h sprint in a claimed 11.94 seconds.

The Audi RS4 wagon is rated to use 9.5L/100km in ADR combined cycle (urban/extra-urban) consumption testing while the slipperier RS5 returns 9.4L/100km in the same test. 

We weren’t able to run accurate or particularly relevant fuel figures on the event but the trip computers showed around 12L/100km in both RS4 and RS5. 

While these numbers are high compared to your average passenger car, the Audi is more efficient than BMW's rivals, and gets remarkably close to the hybrid C63 in the real world.

The fuel tank is quite small for this kind of vehicle at 58 litres. That limits the RS4’s theoretical driving range to 611km. 

Unsurprisingly, the Audi RS4 and RS5 require 98 RON premium unleaded petrol. 

Official combined cycle (urban/extra-urban) fuel consumption is 5.7L/100km.

On test, we recorded 6.7L/100km but we did do a half-day of light off-roading.

This Duster 4x4 has a 55-litre fuel tank so, going by that on-test fuel figure, you could reasonably expect a driving range of about 820km out of a full tank.

The turbocharged 1.2-litre mild-hybrid three-cylinder engine requires 95 RON premium unleaded petrol.

The time allocated to driving the RS4 Avant Competition Plus was fairly limited and we were sadly unable to sample how the highly adjustable coil over suspension performed where it makes most sense — on the racetrack. 

Still, winding country roads between Sydney and the Southern Highlands served up some challenges, demonstrating how the Competition Plus pack changes the character of the RS4 and RS5. 

The only real negative is comfort, specifically over those horrible plastic speed bumps that litter shopping centre car parks. With adaptive dampers, carmakers can set programs for these kinds of obstacles to soften and stiffen the clever shocks at just the right time. Not so the Competition Plus pack cars, which ride these bumps harshly.

That about does it, though, and everything thing else is a net benefit. The steering system addresses some criticism of the earlier RS4s. Further than a retune, the Competition Plus gets a new rack, that is non-progressive with a fixed ratio of 15:1 (instead of 13.3:1) and 2.4 turns lock-to-lock. The reactions to each input feel a hint more faithful. 

When above 40km/h the coil overs come into their own. Even though the RS4 rides firmly it doesn’t constantly jiggle over small bumps. Over sharp-edged hits, the suspension rounds the hits off so, while you feel them, there’s a sense of control and sophistication. 

Having speed limits to contend with means it is essentially impossible to find the limits of grip of the 275/30R20 Continental SportContact 6 tyres on the road and there isn’t much body roll, either.

The RS4 is still rewarding, though, getting up on its toes just enough through a series of bends to feel engaging. It gives an impression of being quite light and at 1820kg it is now considered featherweight next to rivals.

The RS4's Quattro all-wheel drive system favours the rear wheels when driving normally (60 per cent rear) and can send up to 85 per cent of the drive to the back axle. 

The tweaked electronically-controlled rear limited-slip differential amplifies the throttle steer-ability of the RS4, giving you the confidence to squeeze the gas on exit. 

It helps that the Competition Plus bucket seats are a little thinner and set closer to the floor giving you more feedback. This is the key differentiator between the RS4 and RS5 we drove — the buckets make the car feel alive. 

Strong brakes are made up of 375mm front rotors clamped by six-piston calipers. Optional carbon ceramic brakes with larger 400mm front rotors help save 6.5kg and, if you plan to use the RS4 on track, are a smart buy along with a set of Pirelli P Zero Corsa semi slick tyres ($850). 

Really, though, neither the RS4 nor RS5 are the perfect car for the track. They are plenty capable and fast on the road with just enough fun, reward and character thrown in to keep you coming back for more.

My kids are learning to drive in a manual because I reckon being able to drive a manual vehicle remains an important skill to have. I only own manual cars at this point in time and it’s nice to see new cars with manual gearboxes haven’t been done away with just yet.

This all-wheel drive adventure machine is light at 1422kg and punchy, working through a turbocharged 1.2-litre mild-hybrid three-cylinder engine (producing 96kW at 4500rpm and 230Nm at 2250rpm) and a six-speed manual gearbox.

It’s sporty, with precise steering, crisp throttle response and nicely controlled ride and handling. And it’s a whole lot of fun to drive on sealed surfaces.

Throwing it around corners at (legal) speed is a barrel of laughs and driving on fast loose-dirt tracks is damn good for rally-style hilarity, all with the gruff backing track of this little AWD’s tractable petrol engine. Driving the 4345mm long, 2069mm wide and 1650mm high Duster feels like you’re punching a go-kart around a track, in a good way.

The Duster’s suspension deserves a mention here because this package, including an independent multi-link set-up at the rear, yields a firm but well-balanced overall feel.

Its tight turning circle makes it supremely easy to accomplish quick manoeuvres without fuss and it’s also a cinch to park.

Visibility from the driver’s seat is somewhat reduced through different angles to the rear and back along the vehicle’s side, but you get used to that. It doesn’t help that the camera view is muddy looking on the screen.

Those niggles aside, did I mention it’s fun to drive?

It’s not too shabby in low-speed off-road scenarios, either. The Duster is similar to Subaru’s Crosstrek and XV or the Jimny, in that this Renault’s intended use is not as a hardcore rock-crawling beast, it’s not engineered for that sort of thing.

The Duster's all-wheel drive system is well calibrated and quietly effective at detecting wheel-slip and delivering a smooth response. Driven with care, this AWD SUV is capable of off-roading at a level that will surprise some.

It has a 4x4 terrain control system with five modes – 'Auto', 'Eco', 'Mud & sand', 'Snow' and 'Off-road' – as well as a hill descent control system. None of these are engineered to turn the Duster into an off-highway mongrel but they ensure it's able to cope with mild to less-mild off-roading.

The Duster’s ground clearance (212mm) and off-road angles (31-degree approach and 36-degree departure) make it better suited to tackling off-road terrain of the light-to-moderate variety rather than door-sill deep mud holes and the like.

For reference, the Suzuki Jimny has 210mm of ground clearance and approach and departure angles of 37 and 49 degrees. The Crosstrek has 220mm of ground clearance, and approach and departure angles in the off-road-focussed Wilderness of 23.5 and 25.5 degrees.

But it’s still very capable if driven with consideration and well within the limits of its physical dimensions and off-road traction control.

Light off-roading (well-maintained gravel roads and dirt tracks in dry conditions) is fine because that’s well within the Duster’s capabilities and it results in little to no wear and tear on the vehicle.

While the Duster can handle short bursts on firm-packed sand (which I test here), sand-driving puts extra stress on any vehicle, and AWDs don’t have a lot of ground clearance, so they’re prone to bellying out on tall crests in between deeper wheel ruts on a beach.

My advice? Avoid anything beyond a well-maintained dirt track in dry weather and don’t take on any ‘4WD/ high ground clearance only' tracks, prolonged sand-driving or rock-crawling. Anything more rigorous than that and you risk damage to the vehicle’s underbody at a minimum, and mechanical damage and personal injury at worst. You’ve been warned.

The Duster’s off-road capabilities could easily be further enhanced with a set of decent light truck all-terrain tyres but, be aware, even aggressive rubber won’t turn it into a gung-ho off-roader.

For the record, it has unbraked trailer towing capacity of 750kg and braked towing capacity of 1500kg. Maximum towball download is listed as 75kg.

A bonus for Duster owners is that it can be kitted out for adventure via either Renault’s range of accessories – including all-weather floor mats, roof box, roof racks etc – or through Australia’s aftermarket industry.

The Renault Duster 4x4 Evolution (manual) does not have an ANCAP safety rating because it has not been tested.

Standard safety gear includes six airbags, AEB, driver attention alert, lane-keep assist, lane departure warning, traffic sign recognition, rear parking sensors and a reversing camera.

The Duster range does not have adaptive cruise control (only regular ol’ cruise control) or rear cross-traffic alert.

The rear seat has two ISOFIX points and three top-tether child-seat anchorage points.

Audi covers the RS4 and RS5 with a five-year/unlimited kilometre warranty which is now the expected norm across the premium part of the market. 

A five-year service plan can be pre-purchased, costing $3630 for both models with maintenance due annually or every 15,000km. 

After the five-year warranty period, owners can choose to extend the service packaging and warranty for two extra years at a cost of $4260. This can be done twice, extending the warranty up to nine years.

A five-year/unlimited-kilometre warranty with five years of roadside assistance applies to the Duster. That's average for the mainstream market.

Servicing appointments are set at 12 months/30,000km intervals, whichever occurs soonest.

Capped price servicing applies to the first five services with a total cost calculated at $2475 for the all-wheel Duster, with an average per-service cost of $495, which is getting up there for a car in this price bracket.

Renault has more than 70 dealerships across Australia.
