Mazda CX-5 vs Mercedes-Benz CLS53

What's the difference?

The Mazda CX-5 Akera G35 offers small families a great host of premium features, as well as solid power and handling – all in an attractive package. But the emphasis here is on ‘small’ families because it’s on the compact side for a mid-sized SUV and its rivals offer more back seat space.

Its ongoing costs are reasonable and I enjoy driving it, so it gets a 7.6/10 from me.

My son calls out the back seat as a bit squishy but he otherwise likes it. He gives it a 7.0/10

Comfortable when it needs to be and sporty when you want it to be, the CLS 53 is a bit like Mercedes’ Doctor Jekyll and Mr Hyde – or maybe Bruce Banner and the Hulk is a better frame of reference for some.

While it doesn’t excel in any one particular area, its breadth of useability is commendable, but ultimately it might be its all-too-familiar aesthetics that is the biggest letdown.

From the inside, it looks and feels like any other large Mercedes model (not necessarily a criticism), while the exterior – in my opinion – doesn’t go far enough to differentiate it from the CLA.

After all, if you wanted a stylish and sporty sedan, shouldn’t feel special too?

The Mazda CX-5 hasn’t seen much change to the exterior other than a more horizontally-styled grille. It’s a medium SUV with a handsome kerb-side presence thanks to its full-suite of LED lights and 19-inch alloy wheels. It’s an inoffensive design that should appeal to a wide audience.

The interior looks premium with the brown Nappa leather upholstery and black leather trims. The plethora of soft-touchpoints throughout reinforces that the Akera is the top model.

There's one thing I really like about Mazda and that's how it manages to balance the traditional with the new. The cabin is a seamless blend of the two elements.

The instrument panel features a 7.0-inch digital display but still has analogue dials. There's a 10.25-inch multimedia system on the dash but still a bunch of control buttons and dials to press. The gear shifter is coupled with an electric brake, the sunroof is coupled with a manual blind. You get it.

This duology between high-end tech and traditional elements makes the interior feel up to date but very accessible.

Mercedes’ homogenised design is a bit of a double-edged sword, and while the CLS does wear its styling confidently, it probably looks a little too much like the cheaper and much smaller CLA for our tastes.

Both are swoopy four-door coupes from Mercedes-Benz, so of course there will be some similarities, but keen-eyed car spotters will notice some differences.

While the proportions are similar, the longer wheelbase and bonnet line gives the CLS a more mature look, and the extra details found in the head- and tail-lights, and front bumper stand it apart.

The changes to the 2022 version also brings in AMG’s 'Panamericana' front grille, which adds a bit of welcome aggression to the front end.

From the side, the steeply raked roof flows seamlessly into the rear, while the 20-inch wheels fill out the arches well.

All four doors are also frameless, which is always cool to see.

From the rear, quad-exhaust tips hint at the CLS’s sporty intentions, while a prominent rear diffuser and subtle boot lid spoiler also feature.

Inside, the biggest change to the CLS is now the inclusion of the MBUX multimedia system, which keeps it in line with the E-Class, C-Class and other Mercedes models.

AMG sports seats are also fitted, wrapped in Nappa leather and 'Dinamica' fabric upholstery for all pews.

Our test car also came fitted with red contrast stitching and seat belts, adding a racy streak to the CLS cabin.

Have to point out the new steering wheel that comes with the 2022 CLS, though, which mirrors the tiller offered in the new E-Class, and is a step back in terms of functionality.

It looks premium enough thanks to its chunky leather-wrapped rim and gloss black dual-spoke design, but using the buttons, especially when on the move, is difficult and unergonomic.

This design is definitely function over form, and might need a few more revisions to get it right.

Overall, we’d say the CLS is a good-looking car, but does play it a bit too safe with its styling?

Despite sitting in the medium-SUV segment, the CX-5 is on the compact side for cabin space and front passengers benefit the most in terms of leg- and headroom.

Back rowers get a decent amount of headroom but legroom is squishy and my legs press into the back of the drivers seat when its in my driving position, and I'm only 168cm tall!

My seven-year old complained about his space and asked Dad to slide forward for more room, which is something to consider if you have gangly teenagers.

The seat comfort sits on the firmer side for both rows and the electric front seats are narrower and shorter than I like for long journeys but for the A to B trips, they’re comfy enough.

Only the driver’s seat gets powered lumbar support but they both have heat and ventilation functions.

Individual storage is average for this class with a smallish glove box and middle console that has a removable shelf. A deep utility tray, which houses the wireless charging pad and a 12-volt port, sits in front of the gearshift and there are two cupholders in the centre console.

Each door has a shallow storage bin and the front doors also get a skinny drink bottle holder.

For individual storage in the rear, you get map pockets on the rear of the front seats and two cupholders in a fold-down armrest.

The armrest also houses two USB-A ports and the heat function buttons for the outboard seats and it's because of this positioning and the narrower width of the seat, that the back row feels more suited to two, rather than three passengers.

The technology on the whole is easy enough to use but the rotary dial operation of the multimedia system is a bit annoying to access while on the go.

The wireless Apple CarPlay and Android Auto is a great feature and means one less cable to worry about but the built-in satellite navigation with 10-year map updates is a highlight. The head-up display pulls through the nav directions, too, which is always handy.

You also get two USB-C ports and another 12-volt outlet up front, so everyone should be sorted for charging.

The boot features a powered tailgate which is a handy family feature and a temporary spare tyre is located underneath the level floor.

You get 438L of storage capacity with the second row seat upright, which is plenty for my errands and grocery shop. That jumps up to 1340L (VDA) when the rear seats are folded. 

The cargo cover attaches to the lid, meaning it stays out of the way when you're loading stuff into the boot.

Measuring 4994mm long, 1896mm wide, 1425mm tall and with a 2939mm wheelbase, the CLS slots neatly between the E-Class and S-Class in size and positioning.

Up front, occupants are afforded ample room for head, legs and shoulders, while the electronically adjustable seats make it easy to find a comfortable position.

The steering wheel also features a telescoping function – an always appreciated feature – and the expansive glasshouse makes things feel open and airy.

Storage options include a deep door pocket, a cubby found under the armrest, two cupholders and a smartphone tray with wireless charging capabilities.

It’s a different story in the second row, though, as the sloping roofline does noticeably eat away at headroom.

Don’t get me wrong, a six-foot-tall (183cm) adult can still slide in there fine, but the roof is dangerously close to the touching the top of the head.

Leg- and shoulder-room is pretty good in the outboard seats though, while the middle position is compromised by the intrusive transmission tunnel.

In the second row, passengers have access to a bottle holder in the door, a fold-down armrest with cupholders, backseat map pockets and two air vents.

Opening the boot reveals a cavity offering 490 litres of volume, with an aperture wide enough to fit golf clubs or luggage for a weekend getaway for four adults.

The rear seats also fold in a 40/20/40 split fashion, but Mercedes-Benz is yet to detail how much volume is on offer with the rear seats down. And as a traditional sedan, the CLS is less practical than the liftback Audi S7.

When the third-generation Mercedes-Benz CLS-Class hit Australian showrooms in 2018, it was available in three flavours, but the 2022 refresh has trimmed the line-up to just one – the top-spec AMG-tuned CLS 53.

The discontinuation of the entry-level CLS350 and mid-tier CLS450 means the CLS-Class now kicks off at $188,977, before on-road costs, which makes it more expensive than rivals like the Audi S7 ($162,500) and Maserati Ghibli S GranSport ($175,000).

With BMW ditching the 6 Series, the Bavarian brand doesn’t offer a direct rival to the Mercedes-AMG CLS 53, but its bigger 8 Series is offered in a Gran Coupe body style that starts at $179,900.

So, what does Mercedes include in the CLS’s asking price?

Standard equipment includes interior ambient lighting, a head-up display, 12.3-inch digital instrument cluster, power-adjustable and heated front seats, woodgrain interior trim, powered boot lid, rear privacy glass, push-button start, keyless entry, and a sunroof.

As an AMG model, the 2022 CLS is also fitted with a unique steering wheel, sports seats, illuminated door sills, drive mode selector, 20-inch wheels, a performance exhaust, boot lid spoiler and blacked-out exterior package.

Handling multimedia duties is a 12.3-inch 'MBUX' (Mercedes-Benz User Experience) touchscreen, with functions including Apple CarPlay/Android Auto connectivity, digital radio, a wireless charger, satellite navigation and a 13-speaker Burmester sound system.

It’s a long and fully-featured equipment list, for sure, and it’s so extensive that there aren’t really any options available.

Buyers can opt for an 'AMG Exterior Carbon Fibre Package', power-closing doors, and different finishes for the exterior paint, interior trim and seat upholstery – that’s it!

While its nice that everything you’d want comes included in the asking price, it’s hard to ignore the fact that its Audi S7 rival is more than $20,000 cheaper, but also well equipped.

The Akera is an all-wheel drive with a six-speed auto transmission and our test model has the 2.5-litre four-cylinder turbo-petrol engine that produces a maximum power output of 170kW and 420Nm of torque. The turbo ensures it never feels sluggish, even when you’re hitting hills.

Powering the Mercedes-AMG CLS 53 is a 3.0-litre turbocharged inline six-cylinder engine, punching out 320kW/520Nm to all four wheels via a nine-speed automatic transmission and Merc's '4Matic+' AWD system.

A 48-volt mild-hybrid system, known as 'EQ Boost', is also fitted that serves up to 16kW/250Nm from take-off.

The result is a 0-100km/h acceleration time of 4.5 seconds, keeping it on pace with the likes of the 331kW/600Nm Audi S7 (4.6s) and 390kW/750Nm 250kW/500Nm BMW 840i Gran Coupe (5.2s).

While not as brutish as AMG’s eight-cylinder engine, the straight six strikes a great balance between pace and poise that perfectly suits a model like the CLS 53.

The compromise for getting extra power from the turbo is fuel efficiency takes a hit.

The official combined fuel cycle figure is 8.2L/100km but my real-world usage came out at 10L/100km. That’s after mostly open-road driving this week, too, so it’s a bit thirstier than I was expecting.

Based on the combined cycle number and the 58L fuel tank, expect a driving range of around 784km – which is still great for the odd road trip.

Official fuel consumption numbers for the CLS 53 are pegged at 9.2 litres per 100km, while we managed an average of 12.0L/100km in our launch drive.

All of our driving was relegated to country back roads and high-trafficked urban areas however, with no consistent freeway driving.

We’ll reserve judgement on how accurate the fuel economy figures are until after we’ve had the car for longer, but the EQ Boost system is designed to help keep consumption down by being able to coast the engine in particular situations.

The Akera turbo-petrol delivers a decent well of power to dip into and it feels peppy in most situations. Even when you’re overtaking or getting up to speed you don’t feel like you’re nearing the bottom of the power barrel.  

Steering is responsive and the car is agile when you tackle narrow car parks or streets. However, you still get some roll in corners which my passengers felt more than I did.

The cabin is quiet, even at higher speeds and the suspension is firm enough that you feel the bumps but you’re not jostled about. The ride comfort is still good.

I’ve said it before but I love parking medium SUVs because their size is so forgiving in a car park! The Akera is no different and it’s especially easy thanks to the ultra-clear 360-degree view camera system. You also get front and rear parking sensors to help out when needed. 

There are certain expectations on a vehicle when it wears a Mercedes badge, namely it should be comfortable to drive while also dripping with the latest tech. And here the large four-door coupe delivers in spades.

Driving the car is smooth, easy and comfortable when in its default drive setting, you can really sink into the CLS and just eat up the miles in comfort.

There are small niggles, like the 20-inch wheels and low-profile tyres (245/35 front and 275/30 rear) throw up a bit too much road noise into the cabin, but for the most part, around town, the CLS is serene, supple and supremely soothing.

However, switch it over to Sport or Sport+ and the steering gets a bit heavier, the throttle response a bit sharper, and the suspension a bit stiffer.

Does it transform the CLS into a sports car? Not quite, but it certainly dials up driving engagement to a level where you can really have some fun.

Though this isn’t a full-fat AMG in the same vein as an E63 S and doesn’t feature the ubiquitous 4.0-litre twin-turbo V8, the CLS 53’s 3.0-litre six-cylinder engine is still plenty potent.

Coming away off the line feels particularly brisk, likely due to the EQ Boost system adding a bit of poke, and even flat-footing it mid-corner delivers a noticeable surge of urgency from the creamy straight six.

However, the best of the CLS 53 experience, in my opinion, is actually the sound, with the exhaust letting off the right sort of pops and crackles in Sport+ mode on overrun.

It’s rude and obnoxious, but also completely surprising coming from the motoring equivalent of a three-piece dress suit – and I love it!

The brakes are also up to task for scrubbing speed, but our relatively brief time with the car was in extremely wet conditions, so the 4Matic+ AWD system was hugely appreciated.

The Mercedes-Benz CLS is yet to be tested by ANCAP or Euro NCAP, which means there is no official crash-test rating that applies to local market vehicles.

However, the standard safety equipment list is extensive, and covers autonomous emergency braking (AEB), nine airbags, rear cross-traffic alert, blind-spot monitoring, tyre pressure monitoring, a surround-view camera, route-based speed recognition and lane-change assist.

The rear seats also feature two ISOFIX mounting points for child seats.

The CX-5 comes with a five-year/unlimited km warranty, which is average cover for the class but some of its rivals offer longer terms.

There is a five-year, or up to 75,000km capped-price servicing program and services average $423 per workshop visit, which is competitive.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

Like all new Mercedes-Benz models sold in 2021, the CLS 53 comes with a five-year/unlimited kilometre warranty with roadside assist over that period.

This outclasses the assurance period offered by BMW, Porsche and Audi (three-year/unlimited kilometre), and matches that available from Jaguar, Genesis and Lexus, who recently upgraded their offering.

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

The first three planned services will set buyers back $3150, broken down as $700, $1100 and $1350 apiece.
