Suzuki Fronx vs BMW M4

What's the difference?

If you’re considering a small car, particularly if an SUV is the goal, a Suzuki should in most cases be on the shopping list. Back-to-basics motoring is key to the brand’s identity. Its most popular model is a tiny ladder-frame 4X4, for example. Hi Jimny.

The Fronx doesn’t break new ground in any practical sense, but it does come in with a decent price and list of features that should sway plenty of small-car fans in the showroom.

It’s decent to look at, comfortable for the segment, and easy to get used to and drive. The numerical rating on this review betrays just how likeable the car is.

It’s not extremely refined and it starts to lose its dynamic shine on rough roads, but in an urban setting the Fronx should excel.

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.

‘Fronx’ as a name doesn’t exactly scream ‘cute’, but the little SUV has a pretty classically Suzuki design. This is not a complaint at all.

The Fronx is 3995mm long, 1765mm wide and 1550mm tall, but despite its diminutive dimensions the brand has opted to lean into a ‘coupe’ style with a sloping roofline that creates a relatively sporty look, especially for something with a two-digit power figure.

So while some of Suzuki’s designs have been divisive in Australia (Ignis, anyone?) the Fronx takes a slightly more conservative approach by leaning into more design trends than just the coupe-back SUV shape. 

For example, its tail-lights span the width of the tailgate rather than simply flanking the boot as was standard for decades.

The LED daytime running lights at the front are also arranged in a slim, high-up position with a set of headlights below.

Inside is arguably more conservative than out, as the Fronx goes with a fairly standard formula in terms of its layout, with few premium materials (the synthetic leather on the seats feels cheap for example) or adventurous design elements to be found.

But that’s not such a bad thing.

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.

Because for all the conservative, even outdated, styling in the cabin, the fact is it’ll be refreshingly familiar to someone who’s getting out of a car from perhaps even before the year 2000.

Suzuki’s place at the budget end of the new-car market means its customers are likely either quite young and buying their first new car, or relatively old and looking for a cheap, rarely used runabout as the ‘last car’.

For the former, a lack of techy distractions is paramount. For the latter, ease of use wins over cutting-edge tech in most cases. Which is why it’s probably okay that the Fronx’s multimedia touchscreen and software wouldn’t feel out of place almost a decade ago.

It can be a tad fiddly to use at speed, but it’s still more straightforward than the ‘iPad-like’ systems Tesla has made popular, and there are physical controls for important functions like climate control.

There’s also a row of ever-present haptic buttons for volume controls and navigation shortcuts.

The ergonomics of the interior are quite basic, but there are no red flags in terms of visibility, reach, or placement. 

The head-up display is a bonus, but the physical dials on the dash rather than a digital driver display are clear enough, despite again feeling nabbed from a time before head-up displays even existed. 

Space for the front passengers is decent, it’s not cavernous but it’s far from cramped. Elbow rests and seating positions allow for a relaxed ride.

The back seat is a slightly less comfortable place, but at 178cm I can sit behind my own seating position without my knees touching the seat in front, and my head has just enough space above to accommodate the top of a mullet.

Behind that, luggage capacity in the boot is 304 litres, or 605 litres with the rear 60/40 split seats folded.

There’s also no space-saver spare tyre, just a repair kit as standard.

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 Fronx is powered by a 1.5-litre four-cylinder engine with mild-hybrid assistance, driving the front wheels via a six-speed automatic transmission. 

Its outputs are quoted at 76kW and 137Nm, not exactly high-grade stuff and part of the reason the Fronx feels like it takes more than 10 seconds to hit 100km/h.

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'.

Suzuki claims fuel consumption at 4.9L/100km. With its 37-litre fuel tank, the Fronx should be able to manage more than 600km on a single tank, though theoretically its maximum range given its claimed fuel efficiency is 755km.

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.

How you plan to use the Fronx will make a big difference in whether what you’re about to read is a good thing or not. 

The Fronx is a light SUV for a start, so expecting brilliant handling, effortless acceleration and a dead-quiet cabin is going to mean you’re disappointed.

But if you want something easy, engaging and fun, the Fronx might work for you.

Our brief test loop wasn’t entirely indicative of what the Fronx is likely to face day-to-day. With limited time and no preset drive program, the roads within a 20-or-so minute drive of Nagambie, Victoria had to suffice.

The Fronx fared well on the average road, it turned out, with the 1064kg Suzuki managing to feel planted enough to hurl along 100km/h back-roads without complaints. It rides on the same platform used recently by the Suzuki Baleno, something I’ll admit to not having driven.

The rougher roads didn’t faze the light SUV too much, though consistently uneven surfaces made it feel unsettled in some cornering.

Its steering and suspension give enough feedback to make the right inputs easily, though the nature of its light weight and minimal accoutrement in terms of driver assistance make the Fronx feel very rudimentary from the driver’s seat.

At low speeds around the centre of town, the Fronx manages the state’s terrible roads well, though taking off from intersections can be laborious. Much like overtaking, the drivetrain will complain.

And don’t expect its mild hybrid system to do a lot in the way of hard work - or any work at all, really. You could take the hybrid badge off the car, let someone have a drive, and they’d be none the wiser.

From the limited observations on the launch, the Fronx would feel best at home in suburbia or a metropolitan centre more so than on the Hume Highway or the towns dotted alongside it.

Essentially, this is not a refined road trip car for the highway, but its no-fuss approach to getting around means you shouldn’t be surprised if you start seeing them in the car parks at universities or bowls clubs.

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'.

Suzuki has a five-year, unlimited kilometre warranty for its new cars, which is a little behind the curve compared to many budget-friendly brands these days. 

Suzuki does have a five-year servicing schedule, with intervals every 12 months or 15,000km, whichever comes first. Total cost is $2005 over the five years, with services averaging $401, which is not particularly cheap.

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.
