What's the difference?
To say the BMW M4 CS is a hot ticket in Australia is something of an understatement.
Consider this. There is an even more expensive one, the M4 CS Edition VR46 – at a cool $346,900 – and it sold out in less than an hour. Now, granted, Australia only got four examples, but still, demand was running hot.
That car makes this one, the regular M4 CS, seem like an absolute steal. It's only $254,900 (yes, the word 'only' is doing a lot of heavy lifting in that sentence), and it shares the same upgrades, and makes the same monstrous power, as the VR46 – for Valentino Rossi’s 46th birthday – only it does it for around $100K less.
See? A bargain. At least, that's how I'd be justifying it to myself if I had a quarter of a million burning a hole in my pocket.
So, this or a Porsche 911? Read on.
Three years after the fourth-generation Cerato small car rolled into Australian dealerships, Kia launched a mid-life facelift for the sedan and hatch range in mid-2021.
It ushered in styling tweaks including new headlights and Kia’s new logo, as well as more safety tech and a multimedia upgrade.
At the top of the range sits the warmed-up Cerato GT. It’s not quite Hyundai i30 N-level performance, more i30 N-Line. In other words, more than enough performance to keep most people satisfied and enough poke to get away quickly at the lights.
But is the updated version of Kia’s Cerato trying to be something it’s not, or is it a performance bargain?
Read on to find out.
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.
Kia has value and packaging on its side with the sleek and spunky Cerato GT sedan. There’s no shortage of standard gear, it comes with the latest multimedia and safety gear and the cabin and cargo area are spacious and practical.
The powertrain is a winner too. Which is why it’s such a shame that it’s let down so badly by the ride quality.
If you’re going to be driving on various road surfaces, or regularly driving long distance, check out the far more compliant Hyundai i30 N-Line instead.
But if you’ll only ever drive in urban areas – or enjoy the occasional back-road blast – and you can handle the firm ride, there’s still plenty to like about the Cerato GT.
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.
When the fourth-gen Cerato sedan was revealed in US-market Kia Forte guise at the 2018 Detroit motor show, the design was praised for taking inspiration from the sleek Stinger performance sedan.
The facelift has arrived at just the right time to keep the Cerato fresh against the dominant Toyota Corolla, Mazda3 and new Volkswagen Golf.
The sharpened front-end styling features an eye-catching daytime running light signature and the headlights now connect with the redesigned, slimline Kia ‘tiger-nose’ grille in gloss black.
It’s a subtle, yet successful design refresh.
Inside, the Cerato is starting to look its age against rivals like the Golf and Mazda3. Those GT themed additions definitely lift the ambience of the cabin, but the dash layout feels a bit generic and the overall interior design is nothing flash. Especially when you consider the interior of some of Kia’s latest models, like the impressive Sportage medium SUV.
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.
As mentioned, the red stitching throughout, chunky steering wheel and sports seats are welcome additions to the GT cabin.
There are soft-touch materials on the top of the dash but hard plastics on the dash fascia.
There’s no fully digital instrument cluster, but it has a 4.2-inch LCD display in the cluster showing fuel economy and the like. No complaints with the analogue dials and there’s a digital speedo if required.
The update ushered in Kia’s latest multimedia system to the Cerato and it’s a winner thanks to cool graphics, logical menus and its ease of use.
There’s quite a sizable central storage bin and glovebox, while the console houses a key slot, two sizeable cupholders and a second spot for devices adjacent to the charging pad.
The front sports seats look sexy, have excellent side and body bolstering and they’re firm, but comfortable.
A 600mL bottle will just fit into the doors, bit it’s tight.
Sitting behind my six-foot (182cm) frame in the rear, legroom is adequate but toe room is tight. My head was about an inch away from the headliner due to the sloping roofline. The rear seats are also firm.
The Cerato has lower rear air vents, one USB-C port, a map pocket on the passenger side, a central rear armrest with two cupholders, and bottles slot into the doors easier than they do up front.
Kia offers a temporary spare wheel housed under the boot floor. The boot is long, offering an impressive 502 litres (VDA) of cargo space, which is more than other small sedans like the Subaru Impreza (460L VDA) and the Hyundai i30 (474L VDA).
Lower the rear 60/40 seats via the levers in the boot and that space increases further, but they don’t fold completely flat.
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 GT is priced at $35,290 before on-road costs regardless of whether you opt for the four-door sedan (as tested here) or the five-door hatchback, though be aware that Kia Australia regularly runs drive-away pricing campaigns.
There’s not a lot of competition in the warmed-up small car market these days. A number of carmakers have slimmed down their small-car line-ups in the face of falling sales.
Kia’s closest rival is also its mechanical sibling, the Hyundai i30 N-Line sedan and hatch. The Hyundai is cheaper by more than $2500, but the more generously equipped i30 N-Line Premium sedan is a little over $2000 more expensive than the Cerato GT.
The Mazda3 GT sedan and hatch could also be considered a rival and pricing is about on par with the Kia.
Other lower grades in the Cerato range run from $25,490 to $30,640 (MSRP).
The GT benefits from the more premium powertrain offering in the Cerato line-up – the 1.6-litre turbocharged four-cylinder engine shared with the i30 N-Line and the recently discontinued Veloster Turbo.
The GT bodykit adds sporty styling flourishes like a black front and rear diffuser, boot spoiler, dual exhaust, black external mirror caps, red highlights and 18-inch GT alloy wheels.
This theme carries through to the cabin too with features like alloy sports pedals, flat-bottom perforated leather sports steering wheel and leather-appointed seats with red stitching and embossed GT logo.
As the range flagship, the GT also has the most standard equipment. It comes with a sunroof, eight-way power driver’s seat, wireless device charging, an eight-speaker JBL premium sound system, heated and ventilated front seats and dual-zone climate control air conditioning.
The only option fitted to the test car was Snow White Pearl premium paint for $520.
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'.
While all other Cerato grades use a 112kW/192Nm 2.0-litre naturally aspirated petrol engine, the GT benefits from a spicier powertrain.
Under the bonnet is the Hyundai Group 1.6-litre T-GDI four-cylinder turbocharged petrol engine delivering 150kW of power at 6000rpm and 265Nm of torque at 1500-4500rpm. This is the same tune as the Hyundai i30 N-Line.
This is paired with a seven-speed dual-clutch automatic transmission that drives the front wheels. Lower grades use a six-speed torque converter auto. Kia dropped the manual from the S and Sport grades as part of the update.
The GT differs from the rest of the Cerato range as it has multi-link rear suspension, instead of a torsion beam setup. Both the suspension and steering have been tuned for dynamic driving. More on that later.
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.
According to Kia, the Cerato GT sedan uses 6.9 litres of fuel per 100km on the combined cycle. The GT hatch uses 0.1L less.
After a week of mixed driving in the Cerato GT, we recorded a combined fuel consumption figure of 9.0L/100km – a fair bit more than Kia’s claim.
The GT emits 157g/km of CO2 (official combined).
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.
The 1.6-litre turbo engine is a ripper and it’s been put to good use in Hyundai’s i30 N-Line and Veloster Turbo.
It’s just as willing and responsive under the bonnet of the Cerato GT, but they each perform quite differently.
Accelerating from a standing start, there’s mild turbo lag in the Cerato, and some torque steer when accelerating hard.
Once up and running it’s quick, and the seven-speed dual clutch snaps through the gears smoothly while still allowing it to rev freely.
It’s the type of powertrain that is utterly unbothered by things like steep ascents. The Cerato GT just keeps pushing on, without losing momentum.
The downside of that is that the engine is super noisy when pushed and the Kia just doesn’t have sufficient noise suppression materials to counter that. Because of this, it lacks the refinement of its i30 N-Line cousin and the Mazda3.
Steering is weighted on the heavier side but it’s direct and the car goes where you point it.
Like many Kia models, the Cerato GT benefits from an Australian-specific steering and suspension tune. Kia doesn’t have a full performance hot hatch to line up with the i30 N, but the engineers seem to have tuned the suspension to be just as capable as the full-fat i30 N.
That certainly aids dynamic driving in the Cerato GT. It hugs corners and grips the road, avoiding any skipping and with only a hint of body roll.
However, we think Kia’s engineers have made the damper settings too firm, because the Cerato GT’s ride is harsh in virtually all driving environments.
A new, freshly laid road surface in an urban area without any speed bumps was the only time the ride was comfortable during our week with the car.
It crashes over potholes and it’s loud and jarring when you unexpectedly encounter a sharp rut. There’s a bit of vibration through the steering wheel too.
This is disappointing, especially when you consider that the i30 N-Line has a much more supple ride and is the sort of warmed-up hatch or sedan you could easily live with day to day.
We briefly drove the i30 N hot hatch just before we got into the Cerato GT and even that has a more tolerable ride quality than the Kia.
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 Cerato GT achieved a five-star ANCAP crash safety rating in 2019 and it applies to all Cerato variants built after June 2021, except the S and Sport which have four stars because the autonomous emergency braking system offered as standard in those grades can’t detect vulnerable road users like pedestrians and cyclists.
Standard safety for the GT includes auto emergency braking (AEB) with pedestrian and cyclist detection, forward collision warning, rear occupant alert, driver attention assist, rear cross-traffic alert with collision avoidance, blind spot detection and collision avoidance assist, adaptive cruise control, lane keep assist with lane follow assist steering, safe exit warning, front and rear parking sensors and a reversing camera.
At one point, the AEB kicked in pulling out of a parallel street parking spot because it detected a vehicle that had already driven past the car and was several metres ahead.
Kia’s lane keep assist system is generally impressive and functions without issue, but it pulls on the wheel a little. It’s not jolty like systems offered by some other brands.
When lane keep and follow assist are active, it can be fiddly to switch them both off. If you hold the steering wheel-mounted button down, the follow assist stays on but the lane keeping deactivates, so you just have to keep holding the button down until the lane and steering wheel icons in the digital display eventually disappear.
The Cerato, like all Kia models, is offered with a seven-year/unlimited kilometre warranty, and one-year free roadside assist which extends year by year if you service with Kia (up to eight years).
It also comes with a seven-year capped-price servicing plan that costs approximately $3234 over the seven-year period.
Servicing intervals for the Cerato GT are every year or 10,000km, whichever comes first.
