Alfa Romeo 4C vs Mercedes-Benz CLA-Class

What's the difference?

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 broadening of the CLA’s scope in this third-gen version puts it a step ahead of key rivals and raises the compact sedan’s prominence in the three-pointed star’s local line-up. Its combination of quality design, performance and efficiency is compelling. And we’ll drive the battery-electric version as soon as it lands.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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. 

In an impressive feat of aero fine-tuning Mercedes-Benz design and engineering teams have managed to make an already slippery car even more efficient with this new CLA dropping the car’s drag-coefficient from 0.23 to an amazing 0.21.

The sloping, coupe-style profile remains as a CLA signature, complete with frameless doors, flush door handles and aero wheels. 

Hybrid variants sport a conventional radiator grille decorated with a Mercedes-Benz star pattern in chrome and illuminated around its perimeter, while the EVs feature a fully illuminated LED grille display.

And in a move perilously close to branding overkill, the three-pointed star motif is carried into the headlights and tail-lights.

For Latin buffs the interior treatment is minimus extremus, the multi-screen ‘MBUX’ array in the CLA220 we drove dominating the front part of the stripped-back cabin.

From an ergonomic point-of-view, there are no physical controls for ventilation and the only non-digital audio control is on the steering wheel.

But aesthetically, the cabin is clean and simple with touches like ‘floating’ door armrests and a gently rounded front centre console adding to an overall relaxed atmosphere.

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.

At just over 4.7 metres long the CLA isn’t a million miles away from full C-Class length and interior space is generous. In fact, there’s an extra 16mm in height and 12mm in width compared to the model this car replaces.

And in terms of storage there are generous bins in the doors with room for bottles and you can place them in one of the two cupholders in the centre console.

There’s the obligatory bin between the seats, a bay here for wireless device charging and a glove box, plus an extra storage bay under the flying buttress-style console.

In the back seat sitting behind the driver’s seat, set for my 183cm position and there’s plenty of footroom as well as acres of legroom and headroom. 

And part of that is the immense panoramic roof which is covered in all kinds of high-tech coatings to make sure all the light comes through but none of the heat.

Then for storage, again you’ve got bins in the doors with room for bottles as well as a pull-down armrest between the seats with three cupholders in it (one espresso-sized) and drive slot in front of them.

There are netted map pockets on the front seatbacks, individual vents which are always welcome and a couple of USB-C charging ports to keep devices charged.

Boot volume is rated at 405 litres (VDA) and the rear seatback folds 40/20/40 to liberate more storage space if required. And there’s a 101L front boot on electric models. 

There’s a hands-free tailgate on the 220 Hybrid. A 1.6- to 1.8-tonne braked trailer towing capacity is handy, but the fact there’s no physical spare tyre isn’t. Your only option in the case of a flat is an inflator and puncture sealant kit. Not good enough.

The Mercedes CLA kicks off at $66,500 for the entry-level 180, with two other hybrids above it - the CLA200 at $68,100 and CLA220 4Matic sitting at $84,300, all before on-road costs.

Prefer pure-electric? The CLA200 electric will set you back $72,200 with the flagship CLA350 4Matic electric at $91,300.

Which puts the range in the same price ballpark as its German ‘Big Three’ rivals, the Audi A3/S3 sedan and BMW 2 Series Gran Coupe.

Aside from the safety and performance tech we’ll get to shortly, standard equipment in the CLA180 includes heated power front seats, synthetic leather trim, a fixed panoramic glass roof, ambient lighting, ‘high performance’ LED headlights, keyless entry and start, park assist, 18-inch alloys and metallic paint. And the AI-powered assistant integrates ChatGPT, Google Gemini and Bing technologies.

Move up to the CLA200 and you pick up AMG Line elements including different (still 18-inch) rims, sports seats, synthetic leather and synthetic suede trim, a multi-function sports steering wheel, carbon-grain aluminium trim pieces, AMG body styling and what Merc refers to as ‘a sporty engine sound’ driven through the audio system.

Then, aside from its all-wheel-drive powertrain, the CLA220 4Matic includes the ‘MBUX Superscreen’ (combining a 10.25-inch driver display and 14-inch central media touchscreen), a rear light strip, 16-speaker, 850W Burmester 3D surround audio, ‘Multibeam’ LED headlights, 19-inch AMG rims, a head-up display, hands-free boot functionality and privacy glass.

No surprise, the CLA200 electric’s spec is largely the same as its hybrid counterpart, while the CLA350 4Matic electric matches its extra dual-motor performance with the larger 19-inch wheels.

All in all, a decent rather than class-leading list of included features for the class.

There are two option packages. The ‘Premium’ bundle is essentially the standard spec of the CLA220 4Matic, so it’s $0 on that grade but adds $1800 to the hybrid or electric CLA200 and $2340 (including LCT) to the CLA350 4Matic electric.

Similarly, the ‘Sport’ package consisting of privacy glass and 19-inch rims is standard on the CLA220 4Matic but adds $1200 to the price tag on the CLA200 (hybrid or electric).

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. 

Hybrid CLAs combine a 1.5-litre, turbo-petrol, four-cylinder internal-combustion engine (ICE) with a 48-volt electric motor integrated into a new eight-speed dual-clutch transmission with drive going to the front wheels in the CLA180 and 200 and all four in the CLA 220 4Matic.

Mercedes-Benz quotes power and torque outputs for the hybrid’s petrol engine and electric motor individually and the powertrain is able to engage both simultaneously so there are overall output figures, as well. 

The pure-electric models are powered by an in-house developed permanently excited synchronous motor driving the rear wheels through a two-speed transmission, with a second 80kW drive unit added to the CLA350’s front axle for extra performance and all-wheel-drive traction. 

Here’s a panel to explain it all.

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.

Hybrid CLAs are fitted with a 48-volt, 1.3kWh lithium-ion battery and at urban speeds where less than 20kW is needed, can drive using electric power alone, depending on conditions at speeds up to 100km/h. 

Official combined cycle fuel consumption is quoted at 5.4L/100km for the CLA180 and 200, which equates to a theoretical range of close to 800km, rising to 5.8L/100km for the 220 4Matic for a potential range of around 740km. 

On the roughly 150km launch drive through Melbourne's suburbs and up the Yarra Valley north-east of the city we saw an average of exactly 5.8L/100km in the CLA220.

Electric CLAs are underpinned by a specific new-gen EV platform boasting an 800-volt electric architecture and housing an 58kWh LFP battery in the 200 electric and an 85kWh NMC pack in the 350.

Maximum charge capacity is 320kW for a claimed 10-80 per cent charge time of 22 minutes. 

Claimed energy use for the CLA200 electric is 14.4kWh/100km with a range of 470km while the AWD 350 4Matic sits at 14.9kWh/100km with a range of 663km.

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.

The CLA220 4Matic was the only option available for the drive program, but for the record, claimed 0-100km/h acceleration times for the hybrid models step down in roughly one second increments - 8.8 seconds for the CLA180, 8.0sec for the 200 and 7.1sec for the 220 4Matic.

Switch to pure-electric power and the CLA200 electric hits the same speed in 7.5 seconds, while the 350 4Matic electric smashes the five second barrier at a properly quick 4.9sec.

Mind you, the 350 4Matic electric weighs about 2.1 tonnes while the hybrids tip the scales at roughly 1.7 tonnes.

There’s plenty of performance in the 220 4Matic but power delivery is not always linear with the powertrain taking half a beat to pick up after you’ve applied some throttle. Which could be the interface between the combustion engine and the electric motor or the turbo on the engine.

The sports steering wheel is grippy and chunky in the hands, and while the steering itself is nice and accurate, road feel is modest. 

There are two settings for steering weight - Comfort and Sport. We tried both, and yes, you can feel where the car’s going but it’s not exactly an intimate connection between your hands and the front tyres on the tarmac.

Speaking of which, standard rubber on the CLA220 is 225/40 Bridgestone Turanza 6 on 19-inch rims and despite those relatively large wheels the car copes well with bumps and thumps and the coarse-chip surface of rural B-roads.  

Suspension consists of a newly-developed strut-based three-link set-up at the front and multi-links at the rear with all of the major components in alloy to minimise unsprung weight.

The car remains composed and balanced through corners and the sports seats in the 220 are grippy, supportive and comfortable. We spent a couple of hours straight behind the wheel without a hint of discomfort.

The CLA’s super-slippery shape manifests itself out on the highway with minimal wind noise at 100km/h and even more. The big tyres are also quiet so the cabin environment remains refined and peaceful.

Brakes on the 220 are vented discs on the front, solid rotors on the rear. And during some pretty challenging downhill twisty sections we leant on them quite heavily. Push hard and they will bite but are not overly aggressive.

The lane-keeping, driver-monitoring and other assistance features are all there, present and accounted for. But more than ticking the box, they work very well.

The media system is driven by a high-capacity unity engine which is often used in gaming and the graphics and animations are super-smooth. And the latest iteration of the Mercedes-Benz media system works nicely across the enormous screens.

All models feature a 360-degree overhead view and a reversing camera and the 11.2-metre turning circle is not small but not vast. The car is easy to manoeuvre and park.

The new CLA hasn’t been assessed by ANCAP although its sister organisation, Euro NCAP, awarded it a maximum five-star rating in 2025 with mega high scores across the board for occupant and pedestrian protection as well as driver assist systems.

Active (crash-avoidance) tech highlights include auto emergency braking (AEB), blind spot monitoring, lane keeping assist, adaptive cruise control, parking assist, ‘Exit Warning’, ‘Evasive Steering’, ‘Maneuvering Assist’ and more.

Worth noting over-the-air updates cover safety systems, including driver assistance functions.

The airbag count runs to eight, including a front centre bag and there are three top tethers for child restraints across the second row with ISOFIX anchors in the two outer positions.

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.

The CLA is covered by Mercedes-Benz Australia’s five-year/unlimited km warranty with roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery in electric models.

That general warranty is in line with Audi, BMW and other premium players, but it’s worth noting an increasing number of brands in the mainstream market are stepping up to longer seven, eight and even 10-year cover.

Hybrid and electric variants have the same 12-month, 25,000km recommended service interval with a five-year schedule for the hybrids equating to an average of $1342 per workshop visit over that period. Reduced mechanical complexity in the EV models lowers that number to $859. But neither is especially cheap in the context of class competitors.
