Hyundai Accent vs Mercedes-Benz CLS-Class

What's the difference?

It might be getting harder and harder to hide its age, but there is still plenty to like about Hyundai's cheapest car. Those who really love to drive need not apply, and nor should long-distance travellers, but the Accent Sport's alloy wheels, true smartphone integration and plenty of power and USB points will thrill its younger owners, while its long-range warranty and cheap servicing costs don't hurt either.

Still, if you think you can stretch to an i30, you should definitely drive one first.

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?

It looks good, the Accent, just not quite as good as its bigger Hyundai brothers. And that’s got to sting, if only a little bit. 

Words like "subtle", "restyled” and “enhanced design” pepper the Accent’s media information, and so we’re not talking massive changes. But the exterior of the Sport looks sharp, especially in the 'Pulse Red' of our test car. Other colours include 'Chalk White', 'Lake Silver', 'Phantom Black', 'Sunflower' (yellow), and 'Blue Lagoon', but there’s no green, orange or grey paint available.

First, though, don’t let the whole 'sport' thing fool you. You’ll find no Fast and Furious body kit, nor is there much in terms of a rear spoiler, side skirts or a rear diffuser. Instead, a silver-framed mesh grille (a smaller version of the one that adorns the i30) blends into the headlights that then sweep back into the body, while subtle power lines create a little dome in the bonnet, starting at the edges of the Hyundai badge and getting wider as they sweep back across the bonnet. 

Side on, the alloys are clean and simple, and a single style crease runs the length of the body, intersecting both door handles on each side. At the rear, though, the concave body styling doesn’t quite work so well, ending up looking busier than the rest of the car, and leaving it with too much body and not enough rear window.

Inside, as you can see from our interior photos, there is plenty of hard plastic, but there have been some design flourishes that give them a nicer texture and go some way to disguising the fact they’re hard enough to be used as a weapon in a roadside road rage dispute.

But it’s a simple and clean design, with patterned cloth (what, you were expecting leather seats at this price point?) seats, an uncluttered centre cluster and a sparing use of silver highlights that break up the black of the dash and doors.

You can also option everything from tailored floor mats to interior lighting, forming a kind of personalised premium package for the Accent Sport.

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?

It’s every bit as practical as you might expect, the Accent Sport, given that you’re unlikely to be using something this size as a pseudo moving van anytime soon.

The 4155mm long, 1700mm wide and 1450mm high (the sedan is 4370mm long) Accent Sport's interior dimensions feel spacious up front, and while the front seats are a little too flat, the cabin feels airy and light. There are two cupholders up front, too, and there’s room in the front doors for extra bottles. 

Like all Hyundais, the little Accent boasts most of the technology options favoured by younger buyers, like a USB point, an aux connection and two 12-volt power outlets all housed in a tiny storage bin underneath the centre console. There’s a sunglass holder, too, integrated into the roof. 

The backseat is sparse but spacious enough, with enough room for adults to sit behind adults in comfort - at least in the two window seats. That’s about it back there, though, with no technology options, vents or air-con controls.

Boot space is a useable 370 litres in hatch guise, but luggage capacity grows to 465 litres should you opt for the sedan, with both of those figures measured in VDA. Optional roof racks and rails (and other offical accessories like a rubber cargo liner, mud flaps or dedicated bike, snowboard and surfboard carriers) help increase the pint-size Accent’s load-lugging ability.

As does a handy (and optional) cargo liner that helps separate your groceries, sitting neatly under the cargo cover that shields you luggage from prying eyes outside. Perhaps unsurprisingly, you can’t get a factory-offered bull bar.

There are two ISOFIX attachment points, one in each window seat, as well as three top-tether points across the back row.

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 one Accent on offer is powered by a single engine; a petrol-sipping (there’s no diesel, LPG or turbo), 1.6-litre motor that will produce a solid-sounding 103kW (138 horsepower) at 6300rpm and 167Nm of torque at 4850rpm. They are good specs, and it stands up to most competitors in an engine vs engine models comparison. It pairs with a choice of six-speed manual transmission or six-speed automatic transmission.

There used to be a fairly underwhelming 1.4-litre engine size paired with a CVT auto in the now-axed Accent variant, but this bigger engine is much, much better, and makes for much happier reading on the specifications sheet.

The Accent is front-wheel drive only, with no 4x4, AWD or rear-wheel drive options available. It will serve up a 900kg braked and 450kg unbraked towing capacity, with an optional tow bar/ball fitted. Kerb weight is listed as between 1070kg and 1170kg.

The Accent Sport uses MacPherson strut front and torsion beam rear suspension (no sophisticated air systems on offer), and Hyundai doesn’t quote any 0-100km/h, acceleration or speed figures.

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.

For fuel consumption, Hyundai claims 6.3 litres (6.6 litres for the sedan) per hundred kilometres on the combined cycle. But as with all of these manufacturer-supplied figures, there’s always a some sort of variation in the real world km/l fuel economy.

Just how much variation is dependent on how heavy your right foot is, but after my (admittedly city-based) week with the car, the trip computer had my mileage at 11.0L/100km. If you were to adopt an eco mode driving style, that would surely improve, though.

The Accent’s fuel tank size is fairly small, with a fuel capacity of just 43 litres - perfect for the city, less so for long-distance cruising. Emissions are a claimed 146g (154g in the hatch) per kilometre of C02. 

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.

With its sharp design and gleaming alloys, the Accent Sport doesn’t look like an entry-level model, and nor is it immediately obvious that it’s the cheapest way into the Hyundai family. The downside, though, is it does feel that way from behind the wheel.

A little harsher, a little more road noise and a little more gruff than Hyundai’s more expensive models (including the very good i30), it’s the unfair victim of the brand’s staggering success, which has left the Accent feeling a bit old-school by comparison.

That said, it's perfectly suited to inner-city life, and if you’re cruising around using minimal inputs, it does it all smoothly and quietly. The steering feels a little slack at slow speeds, with plenty of dead air when you first start turning the wheel, but none of that bothers you much in the city.

With its sharp design and gleaming alloys, the Accent Sport doesn’t look like an entry-level model.

The grunt from that engine is refreshingly ample for a small car, and provides plenty of punch to get you moving from traffic lights, while the seating position is high enough that vision is great out of every window (except the rear - you’ll be using the reversing camera for that one).

Take it out of town, though, and the refinement begins to vanish. The engine sounds harsh under heavy acceleration, the transmission can be confused - especially around 80km/h, where moving your foot a fraction can force continual changes up or down, like it's wrestling with a big life decision. 

The only other question mark is over the suspension set-up, which for some reason favours sporty firmness in a car unlikely to be asked to achieve anything more dynamic than sitting at 50km/h. The result is a ride that can feel noticeably firm over bad road surfaces.

The Accent’s 140mm ground clearance (not to mention the fact it’s a front-wheel drive city car) should be enough to persuade you not to test its off-road performance. And its turning radius is 10.4m.

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.

It’s a very strong ownership picture, with the Accent Sport covered by Hyundai’s five-year/unlimited-kilometre warranty, and requiring a trip to the service centre every 12 months or 15,000km.

A capped-price servicing plan helps take the guesswork out of your service cost, too, with guide prices at between $245 and $345 per year for the first five years.

One of the most common mechanical questions asked is whether the Accent uses a timing belt or chain, and the Sport uses a timing belt. Check your owners manual for recommended durations between changing  it.

Hyundais traditionally score very well in international reliability rating surveys, which helps protect its second-hand ratings.

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.
