Renault Duster vs BMW M4

What's the difference?

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.

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

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 M4 CS is familiar in all the right ways, but definitely looks significantly jacked up compared to its lesser siblings.

Part of that is the extensive use of carbon everywhere, from its bonnet panels to its roof, front lip, side skirting and boot spoiler. But also because of its super-muscular angles and creases, including the huge dome in its bonnet.

Also exclusive to this M4 CS is the light treatment, with the front LEDs lighting up with yellow highlights the brand says are supposed to be reminiscent of GT racing cars.

At the back, the rear lights are flush with fibre optic lighting, lending a flowing and unique light signature that looks epic at night.

Inside, it's a sea of carbon, with the lightweight racing seats, the dash inserts and the centre console all lined in it. It is a perfectly finished space, though, and one that's also flecked with red, including a 12 o'clock band on the thick-rimmed steering wheel, the seat backs, the contrast stitching and the paddle shifts.

Be warned, though, it takes some acrobatics to climb into or out of the CS. The seat bottoms have these super high edges that double as grab handles, but require some awkward contortions to navigate.

In short, it looks angry, this M4 CS, inside and out.

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.

It all boils down to how you classify practicality in a car like this. I mean, the basic stuff is all there – it's got two doors, four seats and a boot capacity of 440 litres.

It measures 4801mm in length, 1918mm in width and 1399mm in height, and room for front seat riders is good, but less so for anyone you squeeze into the back. There are even ISOFIX points for a child seat.

But if you consider practicality the practical pursuit of performance, then the M4 CS has plenty of perks.

We're talking a $254,900 entry price for the M4 CS, which – despite my attempts at justification – is a lot. Remember, the regular M4 is $168,700, and the M4 Competition is $186,500, so we're talking a sizeable premium here.

BMW justifies that price increase in two ways. The first is scarcity, with the M4 CS limited to just 50 examples in Australia. And the second is by dialling up every aspect of the M4's performance to terrifying levels.

The engine outputs are up, the weight is 20kg down, there are better brakes, better seats, a louder exhaust, a stiffer chassis – it goes on and on.

We'll get to some of the performance stuff in a moment, but here's what else your money buys you with the M4 CS.

It starts outside with staggered alloys, 19-inch up front and 20-inch at the rear, wrapped in track-ready rubber. There's also hi-po 'M Compound' brakes with red calipers, lightweight carbon racing seats that are heated up front, an Alcantara-trimmed steering wheel, the 'M Carbon' exterior package with carbon bonnet and roof, adaptive 'M Suspension' and a titanium exhaust that howls like the winds of hell.

The less performance-focused stuff is similar enough to the other M4 models including a 12.3-inch centre screen with digital radio, Apple CarPlay and Android Auto, a second 14.9-inch screen that handles your driving data and a head-up display. There's also twin-zone climate control, Merino leather upholstery and ambient interior lighting.

But all of that is secondary, really. This is about performance, specifically of the brutal kind.

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.

BMW has found yet more grunt lurking in its trusty 3.0-litre 'M TwinPower' six-cylinder petrol engine, with the M4 CS now pumping out 405kW and 650Nm.

That's a decent jump from the 390kW and 620Nm served up by the M4 Competition, and a giant leap from the outputs of the 'base' M4 – 353kW and 550Nm.

Predictably, then, the CS is the fastest of the lot, knocking off the run from 0-100km/h in 3.4 seconds, compared to 3.5 and 4.2 in the Competition and M4, respectively. The top speed is also dialled up to 302km/h.

All that power is channeled through an eight-speed automatic and sent to all four wheels on demand, with the help of an 'Active M Differential'.

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 M4 CS is fitted with a 59-litre fuel tank, which – given the BMW's official fuel claim of 10.2 litres per hundred kilometres – should deliver a driving range on a full tank of 541 kilometres.

But... BMW also says the regular M4 – you know, the one that makes 52 fewer kilowatts and 55Nm less torque – uses 10.1L/100km, so do with that information what you will.

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 hardest and angriest M4 of all time is, perhaps unsurprisingly, hard and angry. This is a race track specialist, but because I don't happen to own one of those, my first experience with the barking (and barking mad) M4 CS was navigating my way back from BMW's inner-city dealership.

Like it or lump it, you're going to read some Porsche comparisons here, because you're talking not too far off base 911 Carrera money, and suddenly I find the two Germans doing battle for a spot in my dream garage.

First things first, the BMW won't be much chop for daily driving for most people. Happily, I have a sickness for uncomfortable sports cars. It tells me that no compromises have been made in the pursuit of punishing performance.

A good thing, too, because the BMW, at city speeds, can be punishing. Everything feels heavy, the seats aren't overly comfortable – especially the hard bits that tend to dig in when cornering – and it stiff-arms its way over road imperfections, that exhaust booming and barking as it does.

Again, I loved it, and you probably will, too. But it's still not the kind of car I'd relish sitting in the morning peak hour rush in.

But escape the confines of the city and the BMW M4 CS suddenly makes a whole heap of sense. The acceleration is genuinely brutal, and wonderfully theatrical, with that quad-tipped titanium exhaust barking and snarling as you rocket towards 100km/h.

The steering is brilliant, with feedback fed to your wrists via that thick-rimmed wheel, and the entire experience feels sharp, super engaging and edgy.

You can push the M4 hard and fast, and I'm certain my limited talents would run out far before the BMW's would, but there's this thrilling sense of peril sparked by the aggression of the experience, that I love.

It's like the magic of a roller-coaster, I guess. Even if you know nothing is going to happen, you never really know, right? And in that lies the magic.

But back to original question, this or a Porsche 911? There's no doubt a Carrera is a better all-rounder, in terms of comfy commuting and race track fun, but this angry M4 is all shouty theatrics, all of the time.

I bloody love it.

Expect no ANCAP rating here, I'm afraid. But the BMW 4 Series does wear a five-star rating from 2019.

The M4 CS gets six airbags (driver and passenger, side airbags, head airbags), along with what BMW calls its 'Driving Assistant Professional', which bundles active cruise control (with stop and go function), front and rear cross-traffic warning, 'Steering & Lane Control' and 'Lane Keeping with Side Collision Warning'.

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.

The M4 CS is covered by BMW's five-year, unlimited-kilometre warranty, with condition-based servicing available in packs, which will cost you $3530 over five years/80,000km, or $2900 over four years/60,000km.
