BMW M2 vs Mercedes-Benz CLA-Class

What's the difference?

Proving good things still come in small packages, the pint-sized M2 remains my pick of the BMW M range. It's not the perfect daily drive, but I reckon the fun outweighs the foibles.

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.

There have been mixed reviews of the design of the BMW M range, but I reckon this one looks pretty damn good. In fact, I've always thought this kind of hyper-aggressive styling looks better on smaller cars than it does on big ones.

And it certainly is aggressive, right? From the huge bonnet bulges to the meshed out grille and angry rear diffuser, to the staggered alloys and flared wheel arches, to the blocky rear end with its four massive exhaust exits.

But my favourite exterior item has to be the blacked-out carbon roof, which helps shrink the M2 visually, and makes the whole car look more potent.

Inside, it's plenty sporty feeling, with hard-backed sports seats, lashings of carbon-fibre-look trimmings and the bright red M buttons on the steering wheel.

It's nice, but some of the touch points – like the hard plastics on top of the doors, where, if you're like me, you rest your elbow when driving – feel less than premium.

Still, all the tech is present and accounted for, with its digital dash and huge centre screen, and there's no shortage of spaces to connect or charge your phone.

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.

The M2 pocket rocket measures just over 4.5m in length, just under 1.9m in width, and just over 1.4m in height, and it rides on a 2747mm wheelbase. That makes it longer, wider and lower than the model it replaces.

Remember that 'lower' bit, as it will come up again in a moment.

Up front, you don't feel cramped, and there's the requisite cupholders, door pockets and hiding holes, as well as wireless device charging and USB connections.

But remember, this is a two-door, four-seat affair, which cuts into the practicality a little, or a lot.

Swing open the wide front doors, and push the front seat-back forwards, and the entire chair will slide forward automatically.

It does help create more room to climb into the back, but it's still a slightly embarrassing challenge to make getting back there look anything like graceful.

Once there, it's tight. I'm 175cm and my head was firmly pressed into the roof.

You do get your own vents and temp controls, but that's about it. Even the pull-down divider only gives you access to the 390-litre boot, rather than extra cupholders.

You do get two sets of ISOFIX attachment points, though, and let's be honest –  if you're buying this to make Bunnings runs, you've probably got it wrong.

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).

Besides, this is what we're really here for, isn't it? The M2 gets the 'M TwinPower' 3.0-litre twin-turbo inline-six engine, producing a sizeable 338kW and 550Nm, sending that power to the rear wheels via an eight-speed auto or six-speed manual.

BMW says this engine is very, very close to the engine that powers the M3 and M4, and says it will rocket the M2 from 0-100km/h in 4.1 seconds, and to 200km/h in either 13.5 seconds in the automatic, or 14.3 seconds in the manual.

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.

A small fly in the ointment is fuel use, with the M2 said to use 9.7L/100km on the combined cycle. It also drinks 98 RON premium, and is home to a 52-litre fuel tank. Your theoretical driving range is around 540km.

Now, be warned, you'll be bored stiff if you drive it in the way that's required to get it that low. When we were being gentle, we were somewhere between 10.5 and 11.5 litres per hundred kilometres.

Emissions are pegged a 220g/km of C02.

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.

Let's be totally up front here: the BMW M2 isn't the most comfortable vehicle to live with. In fact, I recently climbed out of the M3 Touring, and found that to be more comfortable on broken city streets.

The M2 is fitted with adaptive suspension, but even in its most comfortable settings it can feel rough, bumpy and jarring on bad roads (of which Australia has lots), and unless you're gentle with the accelerator, it can feel a little jumpy when first taking off – a by-product of its prodigious power.

Now, let's be totally up front again: I don't care. The M2 is fun, plain and simple, and for mine, the above is a fair price to pay for something that brings so much joy.

The steering is lovely, the power immediate and the soundtrack intoxicating, and it's the kind of car that's fun no matter where, how far or how fast you drive it.

In fact, fun seems to be the very centre of the M2 proposition, which definitely doesn't take itself too seriously.

For evidence, look no further than the 'M Drift Analyser', buried in a hopelessly busy multimedia system that will have you praising the CarPlay and Android Auto gods.

It will rate your best drift out of four stars, measure it for distance, and basically give you a pat on the back for doing your best hooligan impression (not on a public road, of course).

Fun, then, is the order of the day here. And I bloody love it.

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.

The BMW M2 is covered by a five-year, unlimited kilometre warranty, and servicing is 'condition based', in that the vehicle will tell you what maintenance is required, and when.

You can prepay your service costs at the time of purchase for all BMW vehicles, covering the first five years of ownership, for $3480 (which means $695 per service).

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.
