BMW M Models vs Alfa Romeo 4C

What's the difference?

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.

People might wonder if there’s a reason to buy an Alfa Romeo 4C. It has some great dollar-for-dollar competitors - the Alpine A110 does most of the things the Alfa does, but in a more polished way. And then there’s the Porsche 718 Cayman, which is a considerably more, well, considered option.

But there is no doubt the 4C stands alone, a sort-of cut-price alternative to a Maserati or Ferrari, and nearly as rare to spot on the road as those cars, too. And just like the rollercoaster at Luna Park, it’s the sort of car that’ll leave you wanting another go.

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.

Slap a Ferrari badge on it, and people would think it was the real deal - a pint-sized performance hustler, with all the right angles to get plenty of glances.

In fact, I had dozens of punters nod, wave, mount ‘nice car mate’ and even a few rubber-neck moments - you know, when you drive past and someone on the footpath can’t help but forget they’re walking, and they stare so hard they might well collide with the upcoming lamp-post. 

It really is a head-turner. So why does it only get an 8/10? Well, there are some elements of the design that make it less user-friendly than some of its rivals.

For instance, the step-in to the cabin is enormous, because the carbon-fibre tub sills are huge. And the cabin itself is pretty tight, especially for taller people. An Alpine A110 or Porsche Boxster are much more amenable for day-to-day driving… but hey, the 4C is markedly better than, say, a Lotus Elise for ingress and egress.

Also, as smart as it still looks, there are elements of Alfa Romeo design that have moved on since the 4C launched back in 2015. The headlights are the bit that I dislike most - I had a real thing for the spider-eyes lights of the launch edition model.

But even if it isn’t unmistakably Alfa Romeo, it’s unmistakably a 4C. 

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.

You can’t get into a car this small and expect a lot of space.

The dimensions of the 4C are tiny - it’s just 3989mm long, 1868mm wide and only 1185mm tall, and as you can see from the pictures, it’s a squat little thing. The Spider’s removable roof could be great for you if you’re tall.

I’m six-feet tall (182cm) and I found it to be cocoon-like in the cabin. You feel almost as though you’re tying yourself to the tub of the car when you get into the driver’s seat. And getting in and out? Just make sure you do some stretches beforehand. It’s not as bad as a Lotus for ingress and egress, but it’s still hard to look good clambering in and out of. 

The cabin is a cramped space. There’s limited head room and leg room, and while there is reach and rake adjustment for the steering wheel, the seat only has manual slide and backrest movement - no lumbar adjust, no height adjust… almost like a racing bucket. They’re hard like a race seat, too. 

The ergonomics aren’t terrific - the controls for the air-con are hard to see at a glance, the buttons for the gear select take some learning, and the two centrally-mounted cup holders (one for your double-shot mocha latte, the other for a hazelnut piccolo) are inconveniently positioned exactly where you might want to put your elbow. 

The media system is rubbish. It’d be the first thing to go, if I bought one of these, and in its place would be an aftermarket touchscreen which would: a) actually let you pair to Bluetooth; b) look like it was from sometime after 2004; and c) be more fitting for a car of this price tag. I’d upgrade the speakers, too, because they’re poor. But I can totally understand if those things don’t matter, because it’s the engine you want to hear.

The materials - aside from the red leather seats - aren’t great. The plastics used are similar in look and feel to what you find in second-hand Fiats, but the sheer volume of exposed carbon-fibre does help you forget those details. And the leather pull straps to close the doors are nice, too. 

The visibility from the driver’s seat is decent - for this type of car. It’s low, and the rear window is small, so you can’t expect to see everything around you at all times, but the mirrors are good and the forward vision is excellent.

Look, no-one considering an Italian sports car is likely to be wearing their common sense hat, but even so, the Alfa Romeo 4C Spider is an indulgent purchase.

With a list price of $99,000 plus on-road costs, it isn’t affordable. Not considering what you get for your money.

Standard inclusions consist of air conditioning, remote central locking, heated electric door mirrors, leather sports seats with manual adjustment, a leather-lined steering wheel, and a four-speaker stereo system with USB connectivity and Bluetooth phone and audio streaming. It’s not a touchscreen, so there’s no Apple CarPlay or Android Auto, and there’s no sat nav… but the thing about this car is going the fun way home, so forget maps and GPS. And there’s a digital instrument cluster with a digital speedometer - believe me, you’ll need it.

The standard wheels are a staggered set - 17-inch at the front and 18-inch at the rear. All 4C models have bi-xenon headlights, LED daytime running lights, LED tail-lights and dual exhaust tips. 

Of course, being the Spider model, you also get a removable soft top and you know what’s neat? You get a car cover included as standard, but you’d want to put it in the shed, as it takes up a bit of boot room!

Our car was even further up the pay scale, with an as-tested price of $118,000 before on-roads - it had a few option boxes ticked. 

First there’s that beautiful Basalt Grey metallic paint ($2000), and those contrasting red brake calipers ($1000).

Plus there’s the Carbon & Leather package - with carbon-fibre mirror caps, interior bezels, and a stitched leather instrument cover panel. It’s a $4000 option.

And finally, the Racing Package ($12,000), which includes a staggered set of 18-inch and 19-inch wheels with a dark paint finish, and those wheels are fitted with model specific Pirelli P Zero tyres (205/40/18 up front, 235/35/19 at the rear). Plus theres the sports racing exhaust system, which is awesome, and a racing suspension setup. 

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'.

The Alfa Romeo 4C is powered by a 1.7-litre turbocharged petrol four-cylinder engine, which produces 177kW of power at 6000rpm and 350Nm of torque from 2200-4250rpm. 

The motor is mounted amidships, and it is rear-wheel drive. It uses a six-speed dual-clutch (TCT) automatic with launch control. 

Alfa Romeo claims a 0-100km/h time of 4.5 seconds, which makes it one of the quickest cars at this price point. 

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.

Claimed fuel consumption for the Alfa Romeo 4C Spider is rated at 6.9 litres per 100 kilometres, so it’s no miser.

But, impressively, I saw real-world fuel economy of 8.1L/100km, over a loop that included urban, highway and ‘spirited’ driving on twisty roads.

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.

I said that it’s like a rollercoaster, and it really, truly is. The air doesn’t quite rush through your hair as much, sure - but with the roof off, the windows down and the speedometer constantly edging towards licence suspension, it’s a real hoot of an experience.

It just feels so tight - the carbon-fibre monocoque chassis is rigid and super stiff. You hit a cats-eye and its all so sensitive, you could mistake it for having hit an actual cat. 

Alfa Romeo’s DNA drive modes - the letters stand for Dynamic, Natural, All Weather - is one of those proper examples of this type of system done well. There’s a marked difference between how these different settings operate, where some other drive modes out there are more sedate in their adjustments. There’s a fourth mode - Alfa Race - which I didn’t dare sample on public roads. Dynamic was enough to test my mettle. 

The steering in Natural mode is lovely - there’s great weighting and feedback, super direct and incredibly in touch with the surface below you, and the engine isn’t quite as zesty, but still offers tremendous response on the move. 

It’ll be a difficult choice between this and Alpine A110 and a Porsche Cayman

The ride is firm but composed and compliant in any of the drive modes, and it doesn’t have adaptive suspension. It is a stiffer suspension setup, and though the damping doesn’t change in Dynamic mode, if the surface is anything but perfect you will tram-track and twitch all over the place, because the steering feels even more dialled in. 

In Dynamic mode the engine offers amazing response when you’re at pace, building speed incredibly and before you know it, you’re in licence loss zone.

The brake pedal requires some firm footwork - just like in a race car - but it pulls up strongly when you need it to. You’ve just gotta get used to the pedal feel. 

The transmission is a good thing at speed in manual mode. It won’t overrule you if you want to find the redline, and it sounds tremendous. The exhaust is exhilarating!

With roof on and windows up there’s very noticeable noise intrusion - lots of tyre roar and engine noise. But remove the roof and drop the windows and you get the full effect of the drive experience - you’ll even get some "sut-tu-tu” wastegate flutter. It doesn’t even matter that much that the stereo system is so rubbish.

At normal speeds in normal driving you do need to be considerate of the powertrain because it is finnicky and slow to react at times. There’s notable lag if you’re gentle on the throttle, both from engine and transmission, and the fact peak torque doesn’t come on song until 2200rpm means there’s lag to contend with. 

It’ll be a difficult choice between this and Alpine A110 and a Porsche Cayman – each of these vehicles has a very different character. But for me, this is the most go-kart like and it is, undeniably incredibly involving to drive.

You’re in the wrong spot if you want the latest in safety technology. Sure, it’s at the cutting edge because it has an ultra strong carbon-fibre design, but there’s not much else happening here.

The 4C has dual front airbags, rear parking sensors and an alarm with tow-away protection, plus - of course - electronic stability control. 

But there are no side airbags or curtain airbags, there’s no reversing camera, there’s no auto emergency braking (AEB) or lane keep assist, no lane departure warning or blind spot detection. Admittedly - there are a few other sports cars in the segment which lack safety smarts, too, but 

The 4C has never been crash tested, so there’s no ANCAP or Euro NCAP safety score available.

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.

If you’re hoping that a ‘simple’ car like the 4C will mean low ownership costs, you might be disappointed in this section.

The Alfa Romeo website service calculator suggests that over 60 months or 75,000km (with service intervals set every 12 months/15,000km), you will have to fork out $6625 total. For a breakdown, the services cost $895, $1445, $895, $2495, $895.

I mean, that’s what you get when you buy an Italian sports car, I suppose. But consider you can get a Jaguar F-Type with five years of free servicing, and the Alfa looks like a rip-off. 

The Alfa does, however, come with a three-year/150,000km warranty plan, which includes the same cover for roadside assist.
