Mercedes-Benz CLS-Class vs Smart 1

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?

It’s easy to get lost in marketing hype, but — based on first impressions — the Smart #1 does what it says on the tin. This is a Chinese-built SUV that feels more premium than most, and one which is priced to tempt you from one of the German big three. The warranty isn’t good enough, though, and the multimedia screen can be infuriating, but it drives very nicely, especially on suburban roads.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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?

There is an impossibility pretty model in Smart’s new line-up, but the #1 ain’t it. While the #3 — which has also just launched — is a sleek-looking, coupe-style SUV, the #1 is a top-heavy small SUV that doesn’t shine from every angle.

Front-on, or from a front three-quarter angle, the #1 definitely works, with the brand setting out to remove unnecessary fussiness from the design, leaving smooth and rounded bodywork in its place.

There are no body creases or weird angles here, instead it’s a smooth, fluid-like design that flows from the front LED lights bar to the smooth shoulder lines to the matching light treatment at the rear. 

But it’s at the rear where, for mine, the design begins to fall over. From that angle, the #1 looks skinny and top-heavy, especially when wearing the red hat of the Brabus model.

Still, eye of the beholder and all that.

Inside, though, the #1 kicks all sorts of goals, presenting as a properly premium-feeling EV space that’s swimming with technology and lovely cabin materials.

I particularly love the letterbox-style screen that replaces the traditional dashboard. It’s not distracting or overbearing like some twin-screen set-ups, but clearly shows you the key driving stuff you need when you’re on the road.

Side note, though, the massive central screen is super clear and lightning fast, but as usual you need to spend some (a lot) of time with it to figure out where all the functions are hiding, with most of the car’s key controls hidden within its labyrinth.

And side note two, the background graphics look like they were designed by a cordial-addled child, it is busy, cartoonish and out of keeping with the calm, grown-up nature of the #1’s cabin.

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 Smart #1 measures just under 4.3m long, just over 1.8m in width and around 1.6m in height, and it rides on a 2.75m wheelbase. And the perk of the Smart’s EV powertrain, the brand says, is Mercedes-Benz E-Class levels of space in the back seat, despite the #1’s diminutive footprint.

It’s a big claim, and while I didn’t break out the tape measure I can say the backseat feels plenty generous, and because the rear pew slides forwards or backwards by 15cm, you can choose whether you want more legroom or more luggage space.

Speaking of which, pop the auto-opening boot (by hitting the ‘a’ in the ‘Smart’ lettering, which I couldn’t figure out without help) and you’ll find 323 litres of space with the back seat as far back as it goes, growing to 411 litres with it pushed all the way forward. There’s also a 15-litre frunk.

Smart says the #1 weighs 1800kg, adding it will tow 1600kg — but I’m sure you can imagine the impact a heavy load will have on your driving range.

The #1 is available in three trim levels — the Pro+, Premium and Brabus — and pricing (before on-road costs) climbs from $54,900 to $58,900 and $67,900. 

Brabus, by the way, was a lesser-known Mercedes-Benz tuning arm, a little like AMG, which should give you some idea of what to expect from the performance-badged models.

Anyway, that pricing is good enough to undercut key rivals, including the Volvo EX30 (from $59,990) and BMW iX1 ($78,900), and it’s drastically less than Mercedes-Benz's EQA 250 ($84,900), all before on-road costs.

Also firmly in the Smart’s favour is that there isn’t a cheap-feeling model among them, with even the Pro+ feeling properly well-equipped and premium.

Entry-level cars score 19-inch alloys, a panoramic roof, LED lighting, a powered tailgate and a 12.8-inch central screen with wireless Apple CarPlay and Android Auto, and a 9.2-inch digital dashboard. There’s wireless device charging and a decent stereo, too.

The Premium then adds matrix LED headlights, leather trim, a huge head-up display and a better Beats stereo, while the Brabus scores a unique interior and exterior treatment, better suspension and a launch control function.

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.

There are two drivetrains on offer here - one shared across the Pro+ and Premium, and another delivering the prodigious power of the #1 Brabus.

The first shared option is a single rear motor that delivers 200kW and 343Nm, which is enough to knock off the sprint to 100km/h in 6.7 seconds. Top speed for all models is listed as 180km/h.

The Brabus, though, adds a motor at the front axle, giving it AWD, which ups the outputs to a punchy 315kW and 543Nm, dropping the sprint to 100km/h to a very fast-feeling 3.9 seconds.

It’s a single-speed EV transmission in each, which means smooth, constant power delivery with no traditional ‘steps’, and all get 'Eco', 'Normal' and 'Sport' drive modes, though the only thing they impact is the accelerator response.

You can add weight to the steering, but that’s a separate item accessed elsewhere in the screen’s sub-menus.

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.

All Smart #1 models share the same 66kWh battery, but how far you can travel between charges comes down to the trim you choose, with the WLTP driving range either 400km, 420km or 440km. The Brabus, of course, covers the least ground between charges, owing to its dual-motor set-up and amped up power outputs. 

When it comes time to plug in, all models are equipped with 150kW DC fast-charging capability, and when plugged into said charger, you can expect to go from zero to 80 per cent charged in less than 30 minutes. 

There’s also 22kW AC charging on board in the Premium and Brabus models, which means you can use three-phase power, but plugged into a regular 7.4kWh home wallbox should see you go from zero to 80 per cent charged in 7.5 hours, which means overnight charging should work a treat.

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 #1 and its sister car, the #3, might share powertrains and batteries, but they are designed to drive very differently. The #3 is the sporty one (always code for a firmer ride), while the #1 is supposed to be softer, more comfortable and more city-friendly.

That’s the theory, at least. In practice, I have no idea. My time behind the wheel of the #1 was limited to its most fire-breathing model — the Brabus, which also scores its own suspension components — and soft is not a word that comes to mind once you’re strapped in behind its bright red seatbelt.

It begins with those bonkers power outputs, 315kW and 543Nm, which deliver genuine push-you-back-in-your-seat acceleration every time you stand on the go pedal.

Better still (well, I think so, at least), is that activating its sportiest 'Brabus' mode also unlocks a deep Abarth-style burbling soundtrack that rises and falls with your inputs.

But like most performance EVs, you can also dial the drive experience right back. In its softer drive modes the #1 Brabus feels calm and comfortable and not overly reactive, which makes sense, given the only thing the Brabus mode changes is accelerator sensitivity.

The result, though, is a car that you can tootle around in silently when you want to but hides a nuclear weapon under your right foot when you want to unleash that part of its personality. 

Downsides? It’s got plenty of point-and-shoot power, but in the few corners we managed to find in it, it didn’t quite live up to the all-out-performance badge. There’s a bit too much movement in the body — a symptom of its near-2.0-tonne weight — and it doesn’t feel entirely engaging.

A couple of important caveats, though. We didn’t get long behind the wheel of the #1, and the dull-as-dishwater prescribed drive program revealed little about its true performance potential. So, we’ll have to wait until the model is properly through the CarsGuide garage to give you a deeper dive on this one.

Full credit to Smart on this one, because the #1 comes with a pretty stacked active (crash avoidance) safety tech list, and though our test drive was far from exhaustive, only the speed limit warning (which you can switch off) felt overly intrusive, with the rest just sort of humming away in the background.

The full package includes things like adaptive cruise control, lane keeping assist, traffic-sign recognition and the aforementioned speed limit warning. There’s also AEB, along with seven airbags, all of which has earned the #1 a five-star Euro NCAP safety rating.

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.

Warranty is a definite soft spot, with LSH Auto offering five years or 150,000km, whichever comes first. For reference, other Chinese newcomers include Chery (seven years) BYD (six years) and GWM (seven years), while MG has just shifted to a 10-year warranty.

Still, service intervals are 12 months/20,000km, and you should be able to take your Smart to any LSH Auto Mercedes dealership (in Melbourne, Brisbane and Sydney) or either of the Smart dealerships in Sydney or Brisbane.

Service cost for the first four years averages $611 per workshop visit for the Pro+ and Premium (worth noting the fourth service is a big one) and $780 for the Brabus. Not particularly small numbers.
