Subaru WRX vs Mercedes-Benz CLA35

What's the difference?

Possibly one of the most perfect performance cars you can drive daily for the price. Dynamic and fun to drive, but also easy to live with thanks to the drive modes for extra comfort, the high ground clearance and the practicality that comes with four doors, lots of storage and a big boot.

The tS Spec B is the priciest WRX in the range, but compared to rivals it's also great value. A car I would buy with my own money for sure.

Is the Mercedes-AMG CLA 35 the perfect choice in the sleek sedan’s line-up?

Well, if you are after outright performance, then the answer still clearly lies with the CLA 45. But for those that just want a little more pep compared to the standard CLA range, the 35 is undoubtedly the one to get.

It’s not without its flaws, though, commanding a $15,000 price premium over the CLA 250 and a tougher-than-we’d-like ride, but if you value a more engaging drive and a brisk 0-100km/h time, the CLA 35 should definitely be on your shopping list.

The WRX tS Spec B stands out from its siblings with 19-inch matte-grey alloy wheels with gold Brembo brakes and if you don’t notice any of that, then surely you won’t miss the gigantic rear wing planted on the boot lid.

The air scoop jutting out of the bonnet like a pizza oven is standard across the WRX range and it looks tough. There’s the rear diffuser which also looks beefy but also a bit plasticky, and the quad exhaust, that’s nice, and so is the note which wafts out of them at idle.

The tS Spec B’s Recaro sports seats are also in other tS grades – they do look and feel good, and offer outstanding comfort and support. 

The rest of the cabin is much the same as other WRX grades with a large portrait-style screen, physical buttons for climate control, and yes, that is a traditional, mechanical handbrake you can see in images.

This is a sporty-looking although slightly outdated cabin compared with more modern rivals.

From the front, the CLA 35 exterior oozes style and luxury.

Up front, the sleek and slender headlights emphasise the width of the fascia, while the large Mercedes logo sits proudly front and centre of the CLA’s nose.

There are subtle hints to the CLA 35’s sportiness too, with a slightly bulging bonnet and chiselled lower chin.

The grille is also unique on the 35, with a dual-horizontal slat design instead of the non-AMG CLA’s diamond pattern or the CLA 45’s Panamericana grille.

To my eye, the front of the CLA 35 is actually a bit too tame in styling for an AMG model. I prefer the in-your-face aggression of the CLA 45’s widened track and front grille, while the CLA 35 opts for more subtle styling cues. To each their own, though.

The silver paintwork of our test car probably doesn’t help, and if it was my choice I'd pick 'Sun Yellow' or 'Denim Blue' to stand out a bit more from the sea of black, grey and white German cars out there.

Move to the rear of the car though, and a large rear diffuser, big dual-exhaust outlets and a bootlid spoiler are much more befitting an AMG model.

Step inside the CLA and you will see it adopts the same dashboard design as all new-generation Mercedes vehicles built on the MFA2 platform, with the 'MBUX' dual-screen layout, large air-vents and central touchpad.

Our car was specced out with red-leather interior, which is a bit too loud for my tastes, but a two-tone black leather/titanium grey combo can also be had at no extra cost.

Sitting inside the CLA 35, you can tell it’s a modern car thanks to the clean layout of all the controls, while the screen-heavy dashboard definitely makes it feel tech-focused.

What’s so appealing about the WRX is that despite it being a performance car, it’s based on a regular 'small' sedan and with that comes all the practicality of a four-door, five-seater with a big 411-litre boot.

Space inside is excellent with plenty of room up front, while rear legroom is ample enough for me, at 189cm tall, to sit behind my driving position with plenty of headroom, too.

That all said the Recaro seats up front are on the snug side and I know they’re supposed to be, but I’m just saying they might not suit everybody – and by that I mean everybody.

Those with long legs might also find they have to adjust their driving position when letting out the clutch.

Big door pockets throughout, four cupholders, and hidey-holes for items throughout make for good cabin storage.

There are four USB ports and one 12V outlet, but no wireless phone charging to be found.

Measuring 4695mm long, 1834mm wide, 1399mm tall and with a 2729mm wheelbase, the CLA 35 is definitely a sizeable sedan in the metal.

This actually makes the CLA 35 slightly longer and wider than a non-AMG C-Class sedan that measures 4686 and 1810mm respectively, but don’t expect the same level of practical interior space.

With a heavily sloped roofline, rear-seat comfort takes a hit. My 183cm (6.0ft) frame could not sit upright behind my driving position without tilting my head, while legroom was also slightly lacking.

With such large C-pillars and a small rear window, the second-row can actually feel a little claustrophobic for full-sized adults, but will seat children quite comfortably.

Second-row amenities include air-vents, two USB-C ports, back-of-seat storage nets, bottle holders in the doors, and two cupholders in the fold-down arm rest.

Just like at a music concert though, the best seats in the CLA 35 are up front, with plenty of room for heads, shoulders and legs.

The cabin is also much more light-filled up front, making for a more pleasant experience.

The front seats are electronically adjustable, as is the steering column, but the headrests are fixed.

Storage options include sizeable door bins, a centre console cubby, glove box, two cupholders and a wireless smartphone charger.

Boot space is 460 litres, but can expand with the rear split-fold 40/20/40 rear seats stowed.

Though the boot looks small and shallow on the outside, the aperture is actually quite large, and can easily accommodate a large suitcase with plenty of room to spare.

Priced at $85,500 before on-road costs, the CLA 35 sits $15,300 upstream of the CLA 250 but is $25,700 cheaper than the $111,200 CLA 45.

Standard equipment includes leather interior, dual-zone climate control, electronically adjustable front seats with heating and memory function, keyless entry and push-button start, 64-colour ambient lighting, and a wireless smartphone charger.

AMG specific appointments include 19-inch wheels, a flat-bottomed steering wheel, sports exhaust, high-performance brakes with silver-painted calipers, blacked-out exterior highlights, sports suspension, a racy bodykit and speed-sensitive steering.

Instrumentation is displayed on a 10.25-inch screen, which can be customised and features AMG readouts.

The multimedia system, which includes satellite navigation, digital radio and Apple CarPlay/Android Auto connectivity, is also outputted to a 10.25-inch screen, with inputs including touch, voice commands, centre touch pad or steering wheel controls.

Our test car also came with a ‘Mojave Silver Metallic’ paint finish and 'Vision Package', adding $1190 and $990 to the bottom line each.

The Vision Package adds LED headlights with adaptive high beams, a panoramic glass sunroof and surround-view monitor.

Straddling the lines between a small- and mid-size sedan, the CLA 35 doesn’t really have any direct competitors, which is reflected in its pricing that slots it between the Audi S3 and S4 sedans.

Though the CLA 35 features a long list of equipment, it is still a sizeable chunk of coin, costing more than the C300 sedan and Volvo S60 T8 PHEV, the latter boasting higher engine outputs.

Who doesn’t love the sound of a boxer engine? Well, probably your neighbours if you own a WRX. And while the tS Spec B doesn’t have any more power than any of the other WRXs – with it sharing the same 2.4-litre turbo-petrol four-cylinder boxer engine as the rest of the line-up – the 202kW and 350Nm feel like the perfect amount of power and torque for this package.

It’s probably been about six months since I last drove a car with a manual gearbox, and that shows how rare they’re becoming when you’re testing a new car nearly every week.

The six-speed manual in the tS Spec B has satisfying clunky shifts and a heavy-feeling clutch pedal, but it all plays along perfectly with this engine, sending the drive to all four wheels.

If you’re looking for a version of the tS Spec B with an automatic transmission you’ll be searching forever because this grade only comes with a manual gearbox. There are WRXs with autos – well, a CVT – the entry grade, the RS and the tS.

Powered by a 2.0-litre, turbo-petrol four-cylinder engine, the CLA 35 punches out 225kW/400Nm.

Drive is sent through a seven-speed dual-clutch automatic transmissions to the road via Mercedes’ '4Matic' all-wheel-drive system, enabling a 0-100km/h sprint in the 1603kg sedan in just 4.7 seconds. Top speed is electronically limited to 250km/h.

Though I didn’t get a chance to test the latter, the former certainly feels accurate when taking off from a freeway on ramp, however, there is some hesitation from the turbo in getting on boost.

Peak power comes in at 5800rpm, while maximum torque is available from 3000-4000rpm.

The WRX tS Spec B manual really likes its fuel – it’s a hungry beastie and everybody who’s about to get into the WRX life should be aware that, like most petrol performance cars, it’s not super fuel efficient.

Subaru is beautifully honest with its fuel consumption figures, which have the the WRX tS Spec B using 10.4L/100km in combined driving and 14.2L/100km in urban environment, which is so close to what we recorded - ours was 14.1/100km after mainly urban driving. You'll also have to feed it 95 RON.

The fuel tank is a healthy 63 litres in volume and that should give you a range of 606km – in theory. Do not test this theoretical range somewhere remote, okay?

Officially, the CLA 35 sips 7.5 litres per 100km on the combined cycle, but we managed a 9.9L/100km figure in our week with the car.

The majority of our driving was done in inner-city environments, with the two trips down the freeway to seek out twisty country rounds.

Minimum fuel grade in the CLA 35 is 98 RON.

This may sound strange, but a few months ago I was squished into the tiny cockpit of a 2025 Chevrolet Corvette Z06 sitting at the traffic lights wishing I was in the 2020 Subaru WRX STI beside me. And having driven so many supercars and muscle cars in the past, many costing hundreds of thousands of dollars, I still see the WRX as being such a perfect daily driver performance car.

Sure, it doesn't have Porsche 911 dynamics or the straight-line acceleration of many electric cars, but it's the way the way this boxer engine interacts so beautifully the six-speed manual gearbox, combined with sticky all-wheel drive, a wonderful balance and such direct steering that make the WRX ts Spec B feel exactly right.

The tS Spec B is very much at home in the suburbs dotted with roundabouts and obstacles like speed bumps, but they all become part of the fun of driving this car in the same way that when you let it loose and open road it performs happily and so well, too.

The suspension does feel firm, but part of the big news of this tS Spec B is that it now has a drive mode function and this allow you to adjust the suspension, the steering and the throttle response to either sporty or comfort settings. This just makes this car an even more agreeable thing to live with daily.

The CLA 35 might not offer the outright thrills or breadth of capability of the CLA 45, but don’t think the cut-price AMG offers up a cut-rate driving experience.

From the driver’s seat, one of the cool things about the CLA 35 is that it doesn’t actually look any different from its more expensive sibling.

The drive-mode selector that is now embedded on the steering wheel is fantastic, a feature first seen on the Mercedes-AMG GT 4-door, and makes changing the driving dynamics on the fly an absolute breeze.

In fact, we think all cars where you can select drive modes should have a selector on the steering wheel like this, which lets you quickly and easily dial it up or down while keeping your hands on the wheel.

'Comfort', 'Sport', 'Sport+' and 'Individual' modes are available, while the transmission can also be put into manual mode independently for those that prefer to use the flappy paddles.

Suspension settings can also be tweaked regardless of which drive mode you are in, and it’s this level of customisability that we appreciate.

You want loud exhaust pops and the engine in full attack with manual shifting and the softest suspension? Sure, that’s doable here in the CLA 35. And toning it down to its most comfortable settings is just a flick of the wrist away.

The steering feels a little numb on centre and at slower speeds, though feedback picks right up with speed and is communicative enough when the road starts to get twisty.

Fitted with wide and sticky Michelin rubber, as well as the aforementioned all-wheel drive system, the CLA 35 is certainly not lacking in grip.

The suspension does an okay job of absorbing bumps, but uneven surfaces, like Melbourne’s tram tracks, can send uncomfortable jolts into the cabin if travelling quickly.

In fact, we think the ride comfort of the CLA 35 is probably its weakest aspect, offering not enough variability in its Comfort and Sport settings, and instead settling somewhere in between, regardless of drive mode.

The CLA 35 is ultimately still a fun and engaging sports sedan, though there are some sacrifices made to get it there.

The CLA 35 has not been tested by ANCAP or Euro NCAP, but the standard CLA range was awarded a five-star rating in September 2019.

Standard safety equipment in the CLA 35 includes autonomous emergency braking, automatic high beams, nine airbags, drive attention alert, blind-spot monitoring with exit warning, lane-keep assist, traffic sign recognition and tyre pressure monitoring.

The standard CLA also comes with these features, and was awarded 96 and 92 per cent respectively in ANCAP adult occupant and child occupant protection tests.

For the vulnerable road user and safety assist examinations, the standard CLA scored 91 and 76 per cent respectively.

ANCAP says the AEB system works from seven-200km/h.

Of note, adaptive cruise control is not standard in the CLA 35 like it is in the CLA 45. Instead, buyers will have to tick the 'Driving Assistance Package' box for the feature, which also comes bundled with cross-traffic alert and lane change assist.

The WRX tS Spec B is covered by Subaru’s five-year/unlimited-kilometre warranty, which while the standard for the mainstream segment, is behind the seven-plus terms we're now seeing from a lot of Chinese and Japanese car brands.

Servicing is recommended every 15,000km/12 months and can be expensive compared to other brands, with the five years of capped price servicing coming to $2692.

As with all new Mercedes-Benz models, the CLA 35 comes with a five-year/unlimited kilometre warranty, which is one of the best assurance periods offered by a premium carmaker.

It also comes with five years of roadside assist.

Scheduled service intervals are every 25,000km or 12 months, whichever comes first.

A three-year service plan is available for $2150 for new CLA 35 buyers, saving $500 when priced individually.

Four- and five-year plans are also available, and are priced at $4200 and $4950 respectively.
