Mercedes-Benz CLS-Class vs Alfa Romeo Giulia

What's the difference?

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 Giulia is a love letter to the increasingly lost art of the sporty executive sedan. As refined as it is beautiful and oh-so elegant to drive, it’s a reminder of why we always love Alfa Romeo, even when the odds are against it.

Emotional cars like this are hard to come by and they will soon be gone, replaced by something new. The future is not necessarily worse, but it will be different, so if a sporty European sedan with a combustion engine is calling out to you don’t miss your opportunity to drive the Giulia while it still exists in this form.

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?

Like any good Alfa Romeo should be, the Giulia is a work of art. It’s sleek, sharp, and immaculately proportioned.

This most recent update has artfully refined a formula too good-looking to mess with. The increasingly dorky headlamps from the previous car have been swapped out for a more contemporary all-LED set, with a three-bar DRL pattern.

The grille has also been tweaked for this update for a more modern style, and the Veloce is now graced with the iconic and more aggressive sport two-tone alloy wheels in the traditional five-hole 'tele-dial' style.

It’s effortlessly attractive, and instantly recognisable as an Alfa on the road. I can’t think of a better way to stand out in today’s executive sedan landscape.

The interior has received less of an upgrade for the 2024 model year, with the same core parts. The major change is the old-school analogue instrument cluster being swapped out for a slick 12.3-inch digital unit.

The puzzling thing about this is the 8.8-inch central multimedia screen hasn’t been upgraded in-kind, making a strange contrast between the sharp and fast digital instruments, and the laggy and dull multimedia panel.

At least it effortlessly sits behind the curvaceous design of the dash as to not interrupt a good shape.

There are of course plenty of other touches which I love. The leather seats look and feel the part, as do the real metal paddle shifters which float behind the simple yet refined and sporty steering wheel.

The push-to-start button on the wheel is reminiscent of other Italian sports machines, while the tasteful smattering of leather, gloss plastic, and textured surfaces keep the premium feel on-track.

Some areas I’m not so keen about: Some of the interior plastics, particularly for buttons and toggles, feel cheaper than they should, and the door cards are oddly basic considering how much attention has been given to every other part of this car’s look and feel.

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.

The Giulia is an old-school low-slung sports sedan. Many will prefer the SUV sensibilities of the Stelvio, with its bigger hatch-opening boot, and its higher ride height can better accommodate less mobile passengers, and makes it easier to fit child seats and the like.

For those willing to trade those things away for a superior drive experience, the Giulia is still solid to live with every day, but has a few drawbacks.

For example, those strangely basic door cards offer only a tiny map pocket with a nook I’d hardly describe as a bottle holder.

The centre console offers two larger bottle holders with variable edges, but there’s also not much else in the way of storage in the cabin aside from a smaller-than-average glove box and armrest console box.

The big win for me is the physical dial set and shortcut buttons for all the key climate functions, making it easy to operate while you’re concentrating on driving.

At least the seats are well bolstered, and front passengers are treated to plenty of adjustability. Visibility is okay, and it was easy for me to find a comfortable driving position at 182cm tall.

The rear seat is a similar story. It’s tighter, and you have to duck down below the roofline to get into it.

Once inside, I was pleasantly surprised to find enough room for my knees and somewhere for my feet to slide behind my own driving position, although the centre position is all but useless thanks to an enormous raise for the driveshaft.

Headroom is passable, but you wouldn’t want to be much taller than me. 

There are, again, tiny bottle holders in the doors, and a further two in the drop-down armrest. Rear seat passengers get dual adjustable air vents on the back of the centre console, one USB 2.0 outlet, and elastic nets on the backs of the front seats.

The boot measures 480 litres which is up there with a lot of mid-size SUVs, but because it’s a sedan, access is more limited, and it won’t accommodate as many awkwardly-shaped objects.

The Giulia we’re looking at for this review is the mid-spec Veloce, which costs $74,950 before on-road costs, sitting above the base Ti ($68,450) and below the top-spec Quadrifoglio ($153,700).

Natural rivals from Germany include the Audi A4 45 TFSI ($77,869), BMW 320i M Sport ($80,200) and Mercedes-Benz C200 ($89,900) all of which suddenly make the attractive Alfa look like a not-half-bad deal.

But then there’s always the Genesis G70 (from $63,000 in equivalent turbo 2.0L form) to bring the value equation back to reality.

Standard stuff at this grade includes 19-inch alloys, an 8.8-inch multimedia touchscreen and a 12.3-inch digital instrument cluster (new for the 2024 model year), dark contrast exterior highlights, leather seat trim with heated front seats and steering wheel, aluminium interior detailing and shift paddles with extended leather trim on the dash, updated LED headlights and DRLs, dual-zone climate, push-start ignition and keyless entry, tinted rear windows, and a 14-speaker Harman Kardon audio system.

Performance-wise, the Veloce also scores a limited-slip rear differential to match its punchy engine.

The tech feels a bit old, and the interior has a dated ambiance to it compared to the more open and digitised spaces of its rivals, but there’s something to be said for how organic the Alfa feels. More on this later.

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 Veloce might not pack a Ferrari-derived six-cylinder engine like the Quadrofoglio, but its smaller 2.0-litre four-cylinder turbocharged petrol engine hardly wants for power.

Packing 206kW/400Nm it outpunches six cylinders of old easily, and is still capable of sprinting to 100km/h in a hot-hatch baiting 5.7 seconds to a Vmax of 240km/h.

It even sounds fantastic, as it flies up the rev-range living up to every bit of the Alfa promise. Peak power arrives at 5250rpm, but peak torque hits at 2250rpm.

Smooth shifts are provided courtesy of an eight-speed traditional torque converter automatic transmission.

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 2.0L turbocharged engine has an official combined cycle fuel consumption figure of just 6.1L/100km, although I saw 9.0L/100km in my time with it.

I’ll admit it was being enthusiastically driven, and treated to lots of urban commuting.

The Giulia has a 58-litre fuel tank and requires mid-shelf 95 RON premium unleaded fuel. Its approximate range on a full tank at the official consumption is 951km.

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.

Put simply: The Giulia is a celebration of Alfa Romeo. Yes. Even with a humble 2.0-litre turbocharged engine and an automatic transmission, this is a deeply emotional car. A riveting experience from behind the wheel.

Fly round corners, your eyes wide, exclaiming ‘magnifico!’ as the Giulia gracefully leans in, the rear LSD, sporty tyres, and wonderfully tight steering working together in harmony as you eke out just a smidge of tyre roar.

Laugh out loud to yourself, as you plant the accelerator, hear the muted rumble of the surprisingly angry little engine, and feel the turbocharger kick in half a second later as you power out.

‘Eccezionale!’ You’ll think, as you feel the click of the immensely satisfying metal paddle-shifters, and the transmission responds in-kind, the engine roaring up the revolutions with enthusiasm.

Sure, the Veloce grade is not as raw, or as wild, or near as fast as the top-grade Quadrofoglio, but all of the exciting spirit of  that car is still here, and at a little over half the price, too. The Veloce is an absolute delight to drive.

It has such poise, makes such a fine sound, and does it all so gracefully. This is how you make a car feel as one with the driver.

Even the ride is deeply impressive. It’s not too harsh or noisy, while gifting the chassis just the right amount of lean in the corners and allowing enough play for it to remain controlled over bumps.

Not only does it work well when you’re driving as it's clearly intended to be driven, but around town it’s quiet and refined inside, living up to the promise of a luxury sedan.

The seats and bolstering are great, the visibility isn’t too bad, and while I’ll complain about the slightly laggy software on the multimedia screen, the digital dash is responsive and the physical climate controls are welcome.

It’s not all perfect. If it were, I think it might cease to be an Alfa Romeo and start sprouting BMW badges.

For example, our test car, with less than 2000km on the odometer, had various inconsistent rattles emanating from the plastic garnish around the digital dash, and somewhere behind the back seat.

Regardless, driving this car has made me a little sad Alfa will be putting this wonderful platform behind it in pursuit of more electrified goals.

I can only hope wherever the Giulia nameplate goes next, it retains the spirit of this version.

The same safety equipment suite is standard on every Giulia variant.

Advanced active gear includes auto emergency braking, lane keep tech, blind-spot monitoring with rear cross-traffic alert, driver attention alert, and adaptive cruise control.

It also scores front and rear parking sensors, and a reversing camera with guidelines. 

The Giulia’s maximum five-star ANCAP safety rating expired at the end of last year, as it was originally rated back in 2016. The facelifted model is ‘unrated’ relative to ANCAP’s current standards.

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.

Alfa finally updated its warranty to a more industry-standard five-years and unlimited kilometres in 2022.

Service intervals occur at 12 monthly or 15,000km intervals for the 2.0-litre turbocharged variants. Pricing was not available for the model year 2024 version yet in the brand’s online calculator, but to give you an idea for the pre-facelift version, pricing came in between $345 and $1065 per visit, averaging $573 per year for the first five years of ownership. Not cheap, but not as expensive to run as you might expect.

One thing you might want to keep in mind is depreciation. Boring, I know, but even late model examples of the Giulia and Stelvio have been hit particularly hard by the depreciation stick according to residual values we searched up on Autotrader.

For reference, the Genesis G70 and BMW 3 Series have both fared much better in equivalent 2.0-litre turbo forms.
