Mercedes-Benz CLS-Class vs Holden Calais

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?

A best-of-both-worlds option that should have us questioning our SUV obsession, the Calais Tourer delivers plenty of practicality perks and a higher ride height in a dynamic and car-like package. The equipment levels are spot on, including the comprehensive safety package, and it you act smartly, you'll get a hugely long warranty to boot.  

It sure is thirsty, though, and we can't help but think plenty of owners would be happier with a smaller, more-efficient engine. 

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?

Less an SUV (happily), and more a high-riding wagon, the Calais Tourer borrows a little from the Subaru XV in its exterior design, sporting the same plastic cladding over each wheel arch. Clearly there is a whole heap of shared DNA between the Sportwagon and Tourer, and so it offers similar perks; like its SUV-shaming boot space. 

Elsewhere, the Tourer shares the same soft and rounded edges as the rest of the Commodore range, and while it is genuinely quite handsome from most angles, it is at its best viewed front on, where a simple front-end is bookmarked at each corner by a narrow headlight on top, and an encased fog light below. It’s all a touch understated, sure, but it looks sharp in the metal.

Inside, it’s a clean and functional cabin design, with most of the touchscreen functions controlled by a simple row of four horizontal buttons, and with a gloss-black surround encasing the centre console. The thin leather wheel feels lovely under the touch, and the contrasting door trims and soft-touch materials find their way into the backseat, too. 

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 Tourer serves up identical storage space to its Sportwagon near-enough twin, with 793 litres of storage (to the roof line) with the rear seats in place, and 1665 litres with the rear seat folded down. That’s about 200 litres more than the regular Commodore hatchback.

Where the Tourer does differ from the Sportwagon is in its exterior dimensions, measuring 5004mm in length (versus 4986mm in the Sportwagon) and 1525mm in height (versus 1483mm). Width and wheelbase are identical, though (1871mm and 2829mm), and so the interior space dimensions - like headroom and legroom - are identical no matter which of the estate-style Commodores you opt for. 

The key dimension here, though, is ride height, with the Tourer offering 20mm more ground clearance (42mm greater height overall) than the Sportwagon. That, combined with the on-demand all-wheel-drive system, allows for some light off-roading - though you won’t be conquering Everest.

Up front, expect two cupholders hidden under a gloss-black cover, as well as power and USB connections located in a central cubby. The back seat is home to two extra cupholders hidden in a pulldown divider, and there is room in each of the doors for bottles. The back seat is also home to air vents (but no temperature controls) and two USB charge points located just below the vents.

The Calais has long formed the most luxurious rung of the Commodore ladder, and the wagon-ish Tourer is without doubt the most practical version. It will set you back $45,990 ($47,990 drive-away) in the guise we’ve tested here, and $53,990 In Calais V specification.

Not to be sneezed at, then. But it does arrive with plenty of stuff to help justify your investment.

Outside, you’ll find 18-inch alloys, a handsfree auto-opening boot, heated mirrors, keyless entry with push-button start, a remote start function, rain-sensing wipers and automatic headlights with LED DRLs. Inside, expect leather seats that are heated in the front, a leather-wrapped wheel, dual-zone climate control, standard satellite navigation and a wireless charging pad for compatible phones.

On the technology front, an 8.0-inch touchscreen pairs with an eight-speaker stereo, and it’s both Apple CarPlay and Android Auto equipped. There’s also a genuinely impressive standard safety package, too, but we’ll drill down on that under the Safety sub-heading.

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.

A really rather good 3.6-litre V6 engine Is parked under the bonnet, feeding 235kW at 6800rpm and 381Nm at 5200rpm to all four wheels as required, thanks to an on-demand all-wheel-drive system. The suspension is tuned specifically for its high-riding antics, too.

The grunt is fed through a nine-speed automatic, and while Holden doesn’t quote a specific zero-to-100km/h time, it’s no slouch from the lights. 

The 3.6-litre engine means a braked towing capacity of 2100kg, and an unbraked max of 750kg.

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.

Not so good, I’m afraid. The offical number is on the high-side at 9.1 litres per 100 kilometres on the claimed/combined cycle (though that's less than the equivalent Subaru Outback), but we were averaging a smidge under 14.0L/100km after what was admittedly quite a lot of city driving. Still, that’s high.

Emissions are pegged at 212g/km or C02, and the Tourer’s 61-litre tank will accept cheaper 91RON fuel, or an E10 blend.

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.

Really very good. That 3.6-litre engine (why they haven’t offered the Tourer with the smaller and smarter turbo engine is something of a mystery) might be a touch old-school and a touch thirsty, but it’s a rich and powerful thing, and it gives the Calais-stamped Tourer a perky personality that defies its dimensions.

The Calais Tourer was built in Germany, and fitted with an engine and transmission from the USA, before undergoing local tuning here in Australia (think bespoke steering and suspension tunes calibrated both at the company’s testing facility and after a 200,000km test on Aussie roads), and it’s the last of those Dr Frankenstein ingredients that have had the biggest impact here. 

The Tourer’s ride is fantastic, perfectly poised between firm composure and everyday comfort, and - like most good wagons - it will honestly leave you wondering why so many people are clamouring aboard the SUV train when you can all the space with better dynamics in a humble estate. 

The nine-speed ‘box is smooth and sharp in its operation, too. But the fuel use is a concern. Sure, we spent the bulk of our time in the city, where stop-start traffic naturally uses more fuel. But then, surely so would most owners? 

You’ve got to hand it to the Lion for the standard safety package here, which includes the Holden Eye camera system as standard, adding auto emergency braking (AEB), lane keep assist, lane departure warning and forward collision warning. You’ll also find semi-autonomous parking, a reversing camera and rear parking sensors.

The Calais Tourer adds blind-sport monitoring and rear cross-traffic alert to that pretty comprehensive package. All of which helps the Commodore range qualify for the maximum five-star ANCAP safety rating.

Finally, you can add six airbags and two ISOFIX attachment points to the mix.

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.

Holden has recently relinquished the initial warranty offering, now including the Commodore in its seven-year, unlimited-kilometre warranty program, meaning it mixes with the very best in the aftercare business. For now, at least; normally, the Commodore carries the brand's standard three year/100,000km warranty. But be on the lookout for the return of this deal if you miss out this time.

Service intervals are pegged at 12 months or 12,000kms, and the Commodore falls under Holden’s extensive capped-price servicing program, and it will cost between $259 and $359 for each of the first seven annual services.
