Renault Trafic vs BMW M Models

What's the difference?

The Renault Trafic is a practical and capable workhorse, but then so are some other mid-sized van rivals which sell in greater numbers and come standard with five-star safety credentials. Therefore, a potential buyer must be prepared to accept the Trafic’s inferior standard safety menu (or pay extra to enhance it) to exploit its numerous strengths in a working role.

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.

Our LWB example rides on a sizeable 3498mm wheelbase with four-wheel disc brakes, rack and pinion steering and MacPherson strut front suspension.

The rear suspension uses torsion bar primary springing, supplemented by a pair of secondary coil springs for carrying heavy loads.

Its 1967mm height ensures access to height-limited areas like multi-storey car parks and underground loading zones, but its lengthy wheelbase and front wheel-drive configuration combine to produce a relatively large 13.8-metre turning circle.

The Pro’s no-frills work focus results in extensive use of unpainted dark grey plastic in external areas where bumps and scrapes usually occur in hard-working vans, including the door mirror shells, wheel hubcaps, front/rear bumpers (including the rear pillars from top to bottom) and along the sides.

As a result, the Trafic has a robust and purposeful appearance, combined with a neat and practical cabin design with seating for three on a tasteful blend of contrasting grey fabrics. Hard surfaces are enhanced with satin chrome highlights.

The minimalist dash design (thankfully) provides physical ‘piano key’ buttons for numerous functions, plus there’s a trio of large manual dials to control fan speed, air-flow and cabin temperature in preference to distracting touchscreen prompts.

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.

With its relatively light 1816kg kerb weight and 3070kg GVM, our test vehicle has a substantial 1254kg payload rating which is almost 200kg higher than Toyota’s HiAce LWB (1055kg).

Its 1630kg braked tow rating is also higher than the HiAce’s 1500kg limit and with its 4700kg GCM (or how much it can legally carry and tow at the same time) the Trafic (like the HiAce) can haul its maximum payload while towing its maximum trailer weight.

Standard cargo bay access is through a single kerbside-sliding door or glazed swing-up tailgate, but a right-side sliding door and glazed symmetrical rear barn-doors with forklift-friendly 180-degree opening (the latter as fitted to our test vehicle) are available as options. The cargo bay walls and doors are lined to mid-height.

The load floor is 2937mm long and 1662mm wide, with 1268mm between the rear-wheel housings. So, it can carry up to two standard 1165mm-square Aussie pallets or up to three 1200 x 800mm Euro pallets, secured by a choice of eight load-anchorage points.

The cargo bay offers a competitive 6.55 cubic metres of load volume. Our example is fitted with a 12mm-ply non-slip floor kit and cube shelving kit provided by local industry supplier Autosafe. According to Renault, this tradie-focused set-up retails for $5254 including freight and installation.

The fixed two-passenger bench seat has a lap-sash belt for the central passenger and even someone my height (186cm) can get reasonably comfortable in the middle of a crew of three, albeit with knees competing for space with the prominent dash protrusion that houses the gearshift. By contrast, the outer passenger has ample knee and foot room.

The cabin is equally generous with headroom and displays optimum use of storage space. This includes a large bin in each door which can fit large bottles, with a smaller bin above.

There’s also small-bottle/cupholders on each side of the dash-pad plus a clamshell-lid compartment ahead of the driver, a large open tray in the centre (with two USB-C ports), small closable bins in the lower dash on either side of the driver and a single glove box.

If you choose the glazed bulkhead option, the centre-seat backrest folds forward to reveal an elaborate three-tier workstation, starting with a clipboard on top that can also be detached to use outside the vehicle or mounted vertically in the workstation to face the driver or passenger.

Beneath the clipboard is a hinged work desk, which when raised reveals a shallow felt-lined compartment that’s ideal for hidden storage of phones, tablets, lap-tops etc.

Folding the bench seat’s front-hinged base cushions forward also reveals a cavernous hidden storage compartment underneath.

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 Euro 5-compliant 2.0-litre, four-cylinder, turbo-diesel produces 125kW at 3500rpm and peak torque of 380Nm at 1500rpm.

The six-speed dual-clutch automatic transmission offers the choice of sequential manual-shifting using the shift-lever (no steering wheel paddles) and offers three drive modes comprising 'Normal' (default setting), 'Eco' and 'Performance'.

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'.

Renault claims official combined (urban/extra-urban) average consumption of 6.5L/100km but the Trafic’s dash display was showing 7.9 when we stopped to refuel at the end of our 359km test, of which about one third of that distance was hauling a one-tonne-plus payload.

Our own figure, calculated from actual fuel bowser and tripmeter readings, was higher again at 8.9 which falls comfortably within the usual 2.0-3.0L/100km discrepancy between official and ‘real world’ consumption.

Fact is, any mid-sized van that can produce sub-10L economy in the real world gets a big thumbs-up from us. So, based on our numbers, you could expect an expansive driving range of around 900km from its 80-litre tank.

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.

The driver’s seat offers good comfort with its firm bolstering, fold-down inboard arm-rest and adjustable lumbar support. The only thing missing is a left footrest, just like the one residing in the outer passenger footwell which is of course the driver’s footwell in LHD models.

The synthetic leather-rimmed steering wheel feels nice in your hands and has a premium look. Eyelines to all mirrors are good and the large window in the optional cabin bulkhead allows a clear view through the rear barn-doors, but only if you remove the centre seat’s headrest when the middle seat is unoccupied.

Engine response is at its most energetic from 1500rpm where maximum torque is tapped and it continues to pull strongly all the way to maximum power at 3500rpm.

The decisive shifts of the dual-clutch automatic in Normal (default) drive mode feel well calibrated in terms of optimising the engine’s performance in all driving conditions, which is confirmed by only small differences in response when using the Eco and Performance modes.

Its gearing also ensures the Trafic is well-suited to highway work, requiring only 2000rpm to  maintain 110km/h. It’s even better with the optional bulkhead/cargo barrier as fitted to our test vehicle given it insulates the driver from most cargo bay noise, which can become intolerable in vans at these speeds without this item fitted.

To test its payload rating we forklifted 975kg into the cargo bay. Combined with the weight of the Autosafe fit-out and driver, it equalled a total payload of 1150kg which was only about 100kg less than its legal limit.

The rear suspension compressed about 50mm under this loading, yet still had ample travel to ensure there was no bottoming-out during our test drive. It hauled this one-tonne-plus payload with commendable ease in city, suburban and highway driving, with negligible effects on handling and braking.

It also impressed on our 13 per cent gradient, 2.0km set-climb at 60km/h, quickly downshifting to third gear to easily haul this load to the top.

Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust, but in our experience typical of small displacement (sub-3.0L) turbo-diesels trying to restrain one-tonne-plus payloads on steep descents. Even so, the four-wheel disc brakes comfortably kept speeds under control without a hint of fade.

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'.

The Trafic comes with a five year/200,000km warranty, which includes five years 24/7 roadside assist. Scheduled servicing is 12 months/30,000km whichever occurs first. Capped-pricing applies to the first five scheduled services up to five years/150,000km which totals $3555, or an annual average of $711.

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.
