Summary
Mercedes-Benz CLA-Class
Mercedes has long been the leader in niche filling, and we’d argue that no other model encapsulates that more than the CLA four-door coupe.
Now in its second-generation form, the CLA is based on Mercedes’ MFA2 small car platform that also underpins the A-Class small car range, B-Class tallboy hatchback and GLA crossover, but is actually dimensionally longer than the one-size up C-Class.
However, while the C-Class might offer more conventional styling, Mercedes says the CLA is targeted towards a younger demographic that puts more weight on design and aesthetics.
The previous generation CLA was topped by a hardcore 45 version, which makes a return here, but new this time around is the less-potent, but still AMG-badged, 35 variant to plug the gap between mainstream grades and the range-topper.
After living with the car for a week, here are our thoughts on the new baby AMG CLA.

Audi A3
If it was the original BMW 3-Series that invented the compact luxury car market segment all those years ago, then it’s probably fair to claim it was Audi’s A3 franchise that gave rise to the luxury small-hatch category.
On that basis, any new Audi A3 is news but, in the face of the SUV onslaught (including its own stablemate the Q3) the new small Audi has its work cut out for it.
With this update, there’s refreshed styling, a new interior layout and, for the launch of the new cars, two body styles, a conventionally styled sedan and what Audi calls the Sportback; fundamentally a five-door hatchback but with the German brand’s own flair plastered all over it.

As well as new connectivity and safety tech, the big news is the availability of a mild-hybrid driveline as well as a second powertrain option with more performance from a more conventional layout.
Interestingly, it’s that (mild) hybrid version of the A3 that represents the entry-level variant of the A3. A sign of the times? Perhaps.
As well as the two powertrains, there are two distinct chassis layouts, starting with a front-drive set-up and extending to the option of Audi’s Quattro all-wheel drive (AWD) system.

Verdict
Mercedes-Benz CLA-Class7.8/10
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.
Audi A37/10
Producing a car that takes the end result beyond appliance status is no given in a world car-park dominated by SUVs. But Audi has, over the last few decades, shown it is very good at doing just that and the latest incarnation of its A3 stalwart backs that up.
While it might take a bit of mental gymnastics to understand why the base model gets the hybrid driveline, or why the more expensive variant costs more to option with adaptive cruise-control, the fact remains these are driver’s cars from a company that understands that concept.
Yes, the A3 is a relatively expensive way to arrive at a compact hatch or sedan, but if you value the journey as much as the destination, it will all make sense.
While the technical aspects of the 35 TFSI are interesting, the extra power and all-weather grip of the AWD 40 TFSI seem to be worth the additional dollars to us. The A3 has always been a sporty alternative, meaning the sportiest version is the one for us.
CarsGuide attended this event as a guest of the manufacturer, with meals provided.
Design
Mercedes-Benz CLA-Class8/10
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.
Audi A36/10
It’s actually refreshing in 2022 to see a carmaker putting such an effort into something that isn’t an SUV.
That Audi has bothered with two distinct bodies and two equally distinct drivelines is also one for the books, really.
Technically, the mild-hybrid driveline as seen in larger Audis in recent years is probably the highlight of the new A3, and even though it doesn’t compare with a conventional petrol-electric hybrid, it demonstrates Audi’s attention to detail.
The same goes for the digital instruments which allows the driver to tailor the information displayed at any given time. Need a city map more than you need a tachometer at a particular point in you journey? That’s where this technology comes into its own.
Practicality
Mercedes-Benz CLA-Class7/10
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.
Audi A36/10
Although it’s a compact car externally, clever packaging means there’s ample space inside. Even a tall-ish rear-seat passenger can sit behind a tall-ish driver, and the sculpted rear seat-backs help make that possible.
The only complaint would be that the dark headlining material makes the interior a bit of a cave at times.
Paying more for the 40 TFSI gets you extra cargo nets on the front seat backrests and luggage area, 12-volt sockets in the rear seat and boot. Both versions get floor mats and a centre arm-rest front and rear.
Â
The rear seat in either is split 40/20/40 for a range of possibilities, with the Sportback offering 325 litres (VDA) for the Sportback quattro models, and 380L (VDA) for the 2WD models and its boot capacity is increased to 1145L (VDA) with the rear seat folded flat. The luggage space in the sedan is 390L (VDA) for the quattro AWD version, and a more capacious 425L (VDA) for the FWD model.

Price and features
Mercedes-Benz CLA-Class7/10
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.
Audi A37/10
These are not bargain basement cars, and with a kick-off price of $46,900 for the A3 35 TFSI Sportback (the hatch version) and $49,400 for the sedan in the same specification, that much is obvious.
The fact is, both the new A3 variants represent a fair mark-up on the previous model. But if you look at the post-Covid car market in a macro sense, you can see the same trend across a lot of brands and a lot of previously entry-level models.
Ante up to the 40 TFSI, and the news is no different with an asking price of $53,500 (Sportback) and $56,000 (sedan).
If the price sounds steep on a per-kilo basis, you need to remember this is an Audi we’re talking about and that price premium is part and parcel of a prestige badge. Don’t like it? Go and buy a VW Golf. That’d be Audi’s advice, anyway.
To justify that viewpoint, the A3 is loaded with some impressive standard kit. The 35 TFSI starts things off with Audi’s vaunted 'Virtual Cockpit', wireless phone charging, voice recognition, Apple CarPlay and Android Auto, remote central locking, paddle shifters, park-assist, sat-nav, a 10.1-inch touchscreen, LED headlights, a multi-function steering wheel, automatic lights and wipers, digital radio, cruise-control and dual-zone climate control.
The 40 TFSI adds a range of aluminium trim pieces and garnishes, Audi’s 'Drive Select' system which allows the driver to choose the characteristic of the dampers, steering response, exhaust sound, throttle response and transmission shift points.
The 40 TFSI also adds sportier front seats, a rear spoiler, body kit, extra courtesy lights around the car and details such as a 12-volt socket in the luggage area.
Options on the base model include a 'Comfort Pack' consisting of adaptive cruise-control, electric front seats, heated front seats, auto dimming headlights, heated and folding mirrors, four-way electric lumbar control and 'Adaptive Drive Assist', including 'Emergency Assist.'
That will set you back $2600, while the 40 TFSI can be enhanced with Audi’s 'Premium Package' which adds those same items as well as aluminium-look trim pieces, a better sound system, head-up instrument display and a memory function for the driver’s seat. That adds $4500 to either the 40 TFSI Sportback or sedan.
Under the bonnet
Mercedes-Benz CLA-Class8/10
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.
Audi A37/10
While both versions of the A3 use a seven-speed dual-clutch transmission (no manual gearbox will be offered) there’s not a lot of commonality beyond that.
So let’s start with the 35 TFSI’s mild-hybrid running gear. To begin with, mild-hybrid in this sense refers to a starter motor/alternator unit that is linked to a 48-volt battery (the car also has a conventional 12-volt electrical system).
When coasting, the engine can shut off and the starter switches to alternator mode and harvests the otherwise lost energy to charge the 48-volt battery. This 48-volt system also powers the car’s functions when the engine is switched off.
When the car needs to restart (when the traffic-light goes green) the starter kicks in, using that harvested voltage. There’s also a regenerative braking function, saving the car’s actual brakes for more severe stops.
Unlike a 'normal' hybrid system, there’s no electric motor to help drive the car, but Audi claims a potential fuel saving of 0.4 litres per 100km from the set-up. Any benefit will be most noticeable in urban running where the car is speeding up and slowing down regularly.
The rest of the 35 TFSI is technically interesting, too, with the 1.5-litre four-cylinder turbocharged engine featuring cylinder-on-demand where it can shut down individual cylinders during cruise conditions to save fuel.
When firing on all four, however, the engine is good for 110kW of power and 250Nm of torque, figures which have become almost an industry standard in this sized vehicle.
The 40 TFSI, meanwhile, ditches the hybrid gear for a conventional 2.0-litre powerplant with a turbocharger and 140kW of power. Torque is a handy 320Nm and is developed over a wide range of engine speeds (anywhere from 1500 to 4100rpm).
The other big difference is in the driveline. The 35 TFSI is a front-wheel drive platform while the 40 TFSI uses Audi’s Quattro AWD as it applies to Audis with an east-west engine layout.
That means the car behaves as a front-drive vehicle until the electronics decides more power should be sent to the rear wheels. At that point, anything up to 99 per cent of the available torque can be transferred rearwards via an electronically-controlled multi-plate clutch housed at the rear of the car, just in front of the rear axle.
Efficiency
Mercedes-Benz CLA-Class8/10
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.
Audi A37/10
With all its cylinder shut-off, hybrid tricks and small capacity, the 1.5-litre engine boasts a 5.0 litres per 100km combined cycle fuel economy figure.
Combined with its 50-litre tank, that’s a potential for 1000km between service-station visits. It’s also commendably close to the numbers you’d expect from a similarly sized vehicle with a turbo-diesel engine.
The more conventional 2.0-litre A3 variant, meanwhile, boasts a still-credible 6.7 litres per 100km for the same test. To counter its greater thirst, Audi has fitted a slightly bigger, 55-litre fuel tank.
The headline act, of course, is the base-model’s highway figure which, thanks to the small capacity engine and its reduced pumping losses at small throttle-openings, can get right down into the low-fives (5.0 litres per 100km) in the real world at real highway speeds.
With a tail-wind, you might even see a number starting with four. This is why you don’t need a diesel engine any longer.
Expect the 40 TFSI to use roughly a litre more across every 100km travelled. And in either case, you are stuck with paying for 95-RON premium unleaded.
Driving
Mercedes-Benz CLA-Class8/10
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.
Audi A38/10
Let’s start with the less powerful 35 TFSI, if only because - even though we know better in 2022 - there’s a temptation to think a 1.5-litre engine will be underdone. The reality, however, is that you’re not going to drive this car and judge it as anything other than very resolved.
While it’s true the peak power of 110kW isn’t startling, it’s the way it’s delivered (along with the 250Nm of torque) that sets the mood here.
Like many late-model Audis, this one has an engine with a fizzy, zingy feel that makes you want to rev it just to hear and feel it. And when you do, it pays off with plenty of flexibility and a sophisticated, refined feel.
Whether the mild hybrid driveline is adding anything to the formula is debatable, because the technology is so seamless you won’t pick what it’s doing other than the engine stop-start function, which is one of the better ones we’ve sampled.
Move from the 35 into the 40 TFSI and you immediately notice the extra power and torque on tap. And although it’s still not a hot-hatch by modern standards, there’s always enough urge to make the 40 TFSI a convincing driver’s car.
Again, the power delivery is the key to it all, making more of what the engine has to offer by actively encouraging you to use it. The seven-speed dual-clutch transmission is your friend here.
The extra driveline functionality of the 40 (namely the AWD system) actually means less than you might imagine in day-to-day life. We didn’t get to drive the car in the wet, but it’s fair to say that those conditions (or a loose, gravel road) are really the only ones likely to make a difference to the way the basic platform feels.
That’s for two reasons; the first being the all-wheel-drive is fundamentally on demand anyway and, secondly, the basic platform is so composed and balanced in the first place, that the Quattro system will spend a lot of its time hiding in the background.
The 40 TFSI also get the selectable drive modes which break with tradition by actually making a difference to the way the car feels.
But the reality is that if you took the best bits of every other setting (Comfort, Dynamic and Efficiency) and loaded them into the Individual button, you’d probably wind up with something very close to what the non-adjustable 35 TFSI offers in the first place.
You have to admire the way Audi has made a front-drive car in the A3 steer, handle and talk to the driver in such a clear, precise way.
Yes, the 40’s selectable modes add another layer to that, but only if you can be bothered. Even more than that, the A3 in either form feels like its ultra-stable and safe, while the levels of feel and feedback give the impression they were decided upon by people who enjoy driving.
Safety
Mercedes-Benz CLA-Class7/10
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.
Audi A38/10
Possibly the headline (no pun intended) act here is the inclusion of a centre-front airbag. This is something we’ll be seeing a lot more of in the future, particularly in compact cars, where the proximity of the front-seat passengers can lead to head clashes in a side-impact crash.
Beyond that, the Audi has six airbags including side-curtain airbags.
In terms of driver aids, the A3 sets a high bar for its competitors, and with autonomous emergency braking including pedestrian and cyclist recognition, rear-cross-traffic alert, lane-departure assist and a rear-view camera, most bases are covered.
The major omissions are adaptive cruise-control, but that’s available in the 35 TFSI as part of the $2600 Comfort Package, and in the 40 TFSI as part of the $4500 Premium Package.
Yes, the Premium Package also includes heated, memory front seats, a head-up display, improved stereo and the multi-coloured ambient interior lighting (and more) but it does seem strange that it costs more to option up to adaptive cruise in the 40 TFSI than in the base-model.
The A3 scored the full five stars in ANCAP crash testing in 2020.
Ownership
Mercedes-Benz CLA-Class9/10
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.
Audi A37/10
Audi recently improved its factory warranty from three years to five years and unlimited kilometres. Any new Audi (including this one) sold after January 1 this year is the beneficiary of that change.
Audi specifies service intervals of 15,000km or 13 months.
There’s also the option of a fixed-price servicing program for the first five years of A3 ownership, and that will cost you $2250, for an annual average of $450.
