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.

BMW Alpina B7
You know when you're walking along the footpath and you come to a soft spongey bit that the council have put in around a tree and your mind goes: "Whoah, the ground is bouncy but it looks just like bitumen?!"
Well that's the kind of response you'll get from people when they think they're looking at a regular BMW 7 Series, only to have their world go a bit bouncy when they see the Alpina B7 badge on the back of this car as you're overtaking them at Warp Factor 9000.
And you will be overtaking them like a blur because, thanks to the elves at German tuning house Alpina, the B7 is hugely fast for a five-seat, 5.3m-long, 2.2 tonne limo. But then the B7 is fast for any type of car of any dimensions, because with its 330km/h top speed this beast will outrun a McLaren 570GT. Yes, seriously.
Based on the BMW 750Li long wheelbase, the B7 begins life rolling down the same production line as a regular 7 Series. Alpina then goes on to make so many changes to the engine and chassis that the German government requires the BMW VIN to be replaced with a new one.
Ready to find out more? Well there's so much to see here that things may go a bit weird and bouncy again. Be prepared.

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.
BMW Alpina B77.9/10
The BMW Alpina B7 is a special car destined (like all Alpinas) to be a collector's item, due to its rarity and exclusivity. I asked Alpina just how many current model B7s there are in Australia and the answer was "less than five", which is just as mysterious as most people find the car in general.
The B7 is fast – too fast to enjoy legally on Australian roads – but it is also supremely comfortable and well appointed. For Alpina fans lucky enough to be driven in on,e this would make for a truly rare and niche way to be chauffeured.
Is the BMW Alpina B7 the ultimate fast limousine? Tells us what you think in the comments section below.
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.
BMW Alpina B77/10
This is a good place to start because the B7 looks just like the 750Li it's based on, until you see the first tell-tale signs that it's not one.
There's the front wing with Alpina lettering and the boot-top spoiler, the graphics, which run the length of the car, and the 20-spoke wheels with Alpina badging.
This is late '70s, early '80s styling at its best (and possibly worst), but these special cars can pull off the irony-free look because this is how Alpina BMWs have rolled since 1975, when the E21 320-based Alpina A1/3 was launched.
BMW badges have been left on the bonnet and boot, but there's Alpina B7 BiTurbo lettering in place of the 7 Series identifier.
Most people walked by it in the street thinking it was just a big BMW, others scratched their heads wondering what I'd done to my big German limo and a handful almost dropped to their knees in praise and wonderment at spotting a rare beast like this in the wild.
These people all had their own Alpina stories – one was the third generation of an Alpina-owning family. You become a member a small and passionate club when you buy into this rarefied brand.
The standard B7's cabin is close to identical to the luxurious interior of the 750Li, save for Alpina-embossed stitching in the headrests of the soft, leather seats, the virtual instrument cluster and the Alpina plaque on the centre console denoting the build number.
The B7 is long, low and wide at just under 5.3m end to end, 1.5m tall and 1.9m across. A 3.2m wheelbase means cabin room is more than just spacious.
The B7 rolls off the Dingolfing production line in Germany and is then handed over to Alpina's facility in Buckle, where significant changes take place. Read on to find out how the B7 is different from a regular 750Li.
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.
BMW Alpina B78/10
The B7 is a five-seater limousine although with the fold-down rear centre armrest which houses the media control panel the back is really set up to carry two.
That 3.2m wheelbase means cabin space is enormous. At 191cm tall I can sit behind my driving position with about 30cm between my knees and the seatback. Those rear doors open wide and the entrance is huge, making entry and exit almost as easy as just walking through a doorway. The air suspension also rises and lowers the B7's ride height for better access.
Storage is excellent, with two cupholders and door pockets for rear passengers, along with the area inside the centre armrest.
Up front, the driver and co-pilot have a deep centre console storage bin with split-opening lid, two cupholders and door pockets.
Luggage space is good, with a 515-litre boot.
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.
BMW Alpina B77/10
The B7 lists for $389,955, while a 750li is about $319,000. At this level, $70K seems like a downright reasonable premium to pay for a faster, more powerful, better handling and comfier version of the 750Li.
In this case you're paying more but getting more, although standard features are close to identical. There's adaptive LED headlights, head-up display, night vision with pedestrian detection, a 10.25-inch touch screen up front and two screens in the second row for TV and other media functions.
There's a reversing camera, sat nav, harman/kardon surround stereo and Apple CarPlay. There's leather upholstery, seat massagers in the front and rear, four-zone climate control, heated and ventilated front and rear seats, front and rear parking sensors, auto tailgate, sunblinds for the rear and rear-side windows and proximity key.
The safety features are listed in the section below, and that list is also impressive.
Rivals to the B7 include the Mercedes-AMG S63, which lists for $375,000, the $331,700 Audi S8 and even the Bentley Flying Spur, which almost matches its price at $389,500.
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.
BMW Alpina B79/10
Alpina takes the 4.4-litre twin turbo V8 from the BMW 750Li and rebuilds the engine by hand. Alpina fits its own turbochargers, air-intake set -up, high-capacity cooling system and Akrapovic quad exhaust. Output is 447kW and 800Nm – an increase of a whopping 117kW and 150Nm over the 750Li's grunt.
It's interesting to note that the V12-powered 760Li has a smidge more power, at 448kW, and the same torque output as the B7.
How fast is the B7? Supercar fast – the B7 has a top speed of 330km/h, which will see it outrun a McLaren 570 and almost keep up with a Ferrari F12. That's quite incredible for a 2.3-tonne limousine with three TVs on board. A 0-100km/h time of 4.2 seconds is also hugely impressive.
In comparison, a 750Li has a 0-100km/h time of a not-too-shabby 4.7 seconds, but the car is electronically limited to 250km/h.
An eight-speed automatic transmission shifts gears smoothly, although a little slowly in Normal mode, while Sport and Sport+ add urgency and harder shifts.
Finally, the B7 is all-wheel drive, and those rear wheels are designed to steer slightly for better cornering performance.
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.
BMW Alpina B77/10
The B7 is probably not the car to own if you're concerned about either fuel prices or emissions, but then the twin-turbo V8 may not be as thirsty as you'd think, with Alpina stating that, after a combination of urban and open-road driving, you should only use 9.6L/100km.
My time in the B7 saw me double that usage but this could have had something to do with me turning off the stop-start system and driving in Sport mode constantly.
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.
BMW Alpina B79/10
Who on Earth thinks a BMW 750Li isn't fast enough or comfortable enough, even with all its horsepower, luxurious cabin and technology? Alpina, that's who.
Redevelopment of the 4.4-litre V8 with new turbochargers, a high-capacity cooling system, different air suspension set-up and an exhaust system made by Akrapovic have made this already exceptional car better. Better to drive and better to be driven in.
The ride, even on those 21-inch wheels and low-profile Michelin Pilot Super Sport tyres (255/35 ZR21 on the front and 295/30 ZR 21 on the rear) is incredibly comfortable. I drove it and also had a chance to recline in the back and be chauffeured (by our photographer) and the ride was so composed and refined it was hard to believe I was travelling along some truly awful urban roads with their cracked and pot-holed surfaces.
And it's quiet, too. Which will suit those in the back being transported swiftly from the airport to their next meeting, but if you're after a loud and angry exhaust note then you won't find it in the B7. Sure, from the outside at full throttle the B7 has a menacing growl, but this isn't a BMW M car that will bark and snarl.Â
See, while BMW's M division makes brutal, loud, high-performance versions of their regular cars, Alpina makes comfortable, stealthy, high-performance ones.
All-wheel drive provides fantastic traction and ensures that grunt doesn't just tear the tyres off those rims when you sneeze on the throttle.
And while the air-suspension is soft and comfortable, adaptive dampers adjust for when the road goes twisty, providing impressive handling for a heavy and long car.
Really, though, the B7 is built for long, endless stretches of roads, and the acceleration beyond 100km/h is almost as startling as that from 0-100km/h, as it wants to push straight past 200km/h towards that 330km/h top speed.
Which, unless you know a good lawyer or happen to be one, will send you straight to jail. Yes, the B7 is probably too much car for Australian roads. Only on a German autobahn would a B7 be fully at home.
I felt like I was given a Melbourne Cup-winning racehorse for a week but could only ride it in my suburban backyard.
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.
BMW Alpina B79/10
The Alpina B7 comes with all of the BMW 750Li's safety equipment – this includes AEB, lane-keeping assistance and lane-departure warning, blind-spot warning, active cruise control, night vision with object recognition, auto parking and surround view camera.
Along with the suite of airbags, there's traction and stability control and ABS, as you'd expect.
The 750Li and B7 have not been given an ANCAP score.
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.
BMW Alpina B77/10
The B7 is covered by BMW's three-year, unlimited-kilometre warranty. Servicing is recommended every 12 months or 15,000km. The B7 is covered by BMW special vehicles servicing plan, which means services are cost-free for the first three years of the car's life.
