Mercedes-Benz CLS-Class vs Aston Martin DBS

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 Aston Martin DBS Superleggera is an instant classic, likely heading over a high-end auction block in years to come with a final price far higher than the 2020 ask. But don’t buy it as a collector's item, although it is a beautiful object. Buy it to enjoy. Stunningly fast, thoroughly engineered, and beautifully made, it’s a phenomenal car.

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?

The term Superleggera (Italian for Superlight) is normally associated with Italian automotive coachbuilder Carrozzeria Touring, which has historically applied its fine eye and hand-crafted aluminium body technique to a host of local brands, including Alfa Romeo, Ferrari, Lamborghini, Lancia, and Maserati.

As well as some American, German, and British liaisons, the latter covering classic Aston Martin and Lagonda models through the 1950s and ‘60s (your Silver Birch DB5 is ready for you 007).

But rather than hand-beaten aluminium, here the body panel material is carbon-fibre, and the look and feel of this DBS is the product of Aston Martin’s head of design, Marek Reichman (his name might sound German, but he’s a Brit through-and-through), and his team at the brand’s Gaydon HQ.

Based on the DB11 platform the DBS is a fraction over 4.7m long, just under 2.0m wide, and less than 1.3m tall. But it’s only when you’re close to the Superleggera that its intimidating muscularity comes into focus. 

A giant, black honeycomb grille defines the car’s face, and the single-piece forward-hinging ‘clamshell’ bonnet includes a raised central section defined by longitudinal strakes either side, with deep vents above the front axle line to aid the exhaust of hot air from the engine bay below.

Broad ‘shoulders’ around the front wheel arches are balanced by powerful rear haunches to give the car a beautifully proportioned and imposing stance. But there’s scientific function behind this purposeful form, too. 

The Aston vehicle dynamics team went all out with wind tunnel testing, Computational Fluid Dynamics (CFD) modelling, aerothermal and performance simulations, as well as real-world track testing to refine this car’s aero efficiency. 

The DBS Superleggera’s overall drag coefficient (Cd) is 0.38, which is commendably slippery for a brawny 2+2 GT. But it’s the fact that in parallel with that number it’s able to generate a humongous 180kg of downforce (at 340km/h VMax) that’s remarkable.

The aero trickery includes a front splitter and airdam working in unison to accelerate airflow under the front of the car, delivering downforce and cooling air to the front brakes. 

From there the ‘open stirrup and curlicue’ device at the top of the front wheel wells vents air to reduce lift, and create vortices which reattach the aero wake from the front wheels to the side of the car.

The ‘C-Duct’ starts with an aperture behind the rear side glass funneling air through the underside of bootlid to a subtle ‘Aeroblade II’ spoiler at the rear of the car. A close to flat underside also feeds air to an F1-inspired double diffuser under the rear end.

No gaudy wings or giant spoilers, just a subtly effective and thoroughly engineered aero profile.

Slim but distinctively Aston Martin LED tail-lights combine with a series of horizontal character lines across the rear to enhance the car’s visual width, and giant 21-inch dark rims fit the car’s proportions perfectly.

Slipping behind the wheel is the full hand-in-leather glove experience. The broad dashtop is split by a vaguely teardrop shaped centre stack with the classic ‘PRND’ transmission buttons and an illuminated push-button starter in the centre.

The compact instrument binnacle, housing a configurable digital display, imparts a quiet sense of purpose, and the Mercedes-AMG sourced media system, complete with rotary control dial, feels familiar. Overall, simple, subtle, yet hugely impressive.

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 notion of practicality doesn’t naturally align with a 2+2 GT, but a wheelbase measuring 2805mm means there’s enough space between the axles to provide generous accommodation for front seat occupants at least.

And the usual compromises presented by long coupe doors are reduced by the DBS’s swinging slightly up as they open, and down as they close. A genuinely useful touch.

The driver and front seat passenger are snug but not cramped, which feels right in this context, and they’re provided with a lidded central box, which doubles as an armrest between the seats.

Flick the switch and its power-operated top slides back in stages to reveal two cupholders and a general storage space with a 12V power outlet, two USB-A ports, and an SD card input at the rear.

There’s a small coin tray in front of the multimedia dial in the centre console and long door pockets, but bottles will be a struggle unless you’re happy to lay them on their side.

The ‘+2’ seats scalloped out of the rear bulkhead, look super cool (especially with our car’s Triaxial quilt trim) but for anyone in the vicinity of average adult height they’ll feel distinctly inadequate.

Legs or a head aren’t viable options so this space is best reserved for the kids. And there are two 12V sockets in the rear to help keep their devices charged, and them calm.

Boot volume is a useful 368 litres, and the aperture curves forward at the top which helps with loading larger cases, but remember the rear seats don’t fold.

There are small lockers hidden in the back wall, one containing a flat tyre repair kit, so don’t bother looking for a spare of any description.

The DBS Superleggera is like a finely tailored suit. Impressive, but not flashy, while the finish is impeccable, the materials used are top-shelf, and attention to detail is remarkable. And like anything that’s been carefully crafted and largely hand made, the price is substantial.

Before on-road costs like registration, dealer delivery charges, and compulsory insurance, this Aston will set you back $536,900.

The $500K ballpark contains some heavy-hitting competition, the most closely aligned being Bentley’s 6.0-litre W12-engined Continental GT Speed ($452,670), the 6.3-litre V12-powered Ferrari GTC4 Lusso ($578,000), and Porsche’s 3.8-litre twin-turbo flat-six 911 Turbo S ($473,900). All 2+2s, all insanely fast, and bristling with luxury features.

So, aside from the safety and dynamic tech detailed later in this review, what does this special DBS deliver in terms of standard equipment?

First, there’s the Aston Martin, nine-speaker premium audio system (including 400W amp and digital radio, but no Android Auto or Apple CarPlay), a multimedia system managed via an 8.0-inch LCD screen and console touchpad/dial controller system (sourced from Mercedes-AMG), satellite navigation, a Wi-Fi hub, and a 360-degree camera with ‘Parking Distance Display’ and ‘Park Assist.'

Standard upholstery across the seats, dash, and doors is ‘Caithness’ leather (Aston says a dry-drumming process gives it a particularly soft feel) combined with Alcantara (synthetic suede) and ‘Obsidian Black’ leather on the faceted (think square-ish) sports steering wheel, finished off with the DBS logo embroidered into the headrests. 

The ‘Sports Plus’ performance seats (with memory) are 10-way electrically-adjustable (including lumbar) and heated, the steering wheel adjusts electrically, ‘interior jewellery’ (trim elements) are ‘Dark Chrome’, and cabin inlays are ‘Piano Black.’

Also included are a configurable digital instrument display, dual-zone climate control, keyless entry and start, rain-sensing wipers, cruise control (not adaptive), auto LED (high and low beam) headlights and DRLs, as well as LED tail-lights and dynamic indicators.

The ‘Exterior Body Pack’ consists of gloss-finish carbon-fibre across the rear bumper, bootlid flap spoiler. rear diffuser, and front splitter, and the standard rims are 21inch forged ‘Y spoke’ alloys, with (big) dark anodised brake calipers behind them.

All up, a subtle and exclusive approach to an equipment package that’s as much about the overall quality of the car’s design, engineering, and execution as it is about individual features. 

But on the subject of features, ‘our’ car was kitted out with a series of special options, namely: Bang & Olufsen audio - $15,270, ‘Leather colour option special’ ‘Copper Tan’ (metallic) - $9720, contrast stitching - $4240, vented front seats - $2780, power seat bolsters - $1390, Triaxial quilting - $1390, headrest embroidery (Aston Martin wings) - $830.

That’s $35,620 worth, and there were still other boxes ticked, like a colour keyed steering wheel, smoked rear lamps, plain leather headlining, ‘Shadow Chrome’ rims, even an umbrella in the boot... but you get the idea. 

And if you really want to personalise the car, ‘Q by Aston Martin’ offers a collection of “unique enhancements beyond the scope of the core option range.” Then ‘Q Commission’ opens up a bespoke, atelier-style collaboration with the Aston Martin design team. Possibly an entirely custom car, or just machine guns behind the headlights.

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 DBS Superleggera is powered by an all-alloy, 5.2-litre twin-turbo V12, featuring dual-variable camshaft timing and direct-injection to produce 533kW (715hp) at 6500rpm and 900Nm from 1800-5000rpm. 

In line with the personal nature of this car’s build, a brushed metal plaque sits on top of the engine, proudly stating ‘Hand built in England’, and noting that a final inspection was carried out (in our case) by Alison Beck. 

Drive goes to the rear wheels via an alloy torque tube and carbon propshaft to a (ZF-sourced) eight-speed automatic transaxle, incorporating a mechanical limited-slip differential, with manual shifts available via wheel-mounted paddles.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the DBS emitting 285g/km of CO2 in the process.

In just under 150km with the car, covering city, suburban and freeway running (as well as a sneaky B-road session) we recorded an average of 17.0L/100km, which is a sizeable number, but kind of expected for a roughly 1.7-tonne, V12-powered meteor on wheels.

Stop-start is standard, minimum fuel requirement is 95 RON premium unleaded, and you’ll need 78 litres of it to fill the tank (which translates to a real world range of approximately 460km).

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.

Once you dip under three and half seconds for the sprint from 0-100km/h strange things happen to your field of vision. Faced with that kind of acceleration, it instantly narrows, your brain instinctively focusing attention on the road ahead because it senses something borderline unnatural is going on.

Claiming just 3.4sec for the DBS Superleggera to hit triple figures (and 0-160km/h in 6.4sec!) we felt obliged to validate the number, and sure enough peripheral vision blurred into nothingness as this brutal machine delivered its shock and awe performance.

And the aural accompaniment is suitably intense, thanks to the electronically-controlled (stainless steel) exhaust, with active valves and quad tail pipes, orchestrating the brilliantly guttural and raucous ‘sound character.’ 

Pure pulling power is immense with all 900Nm of maximum torque available from just 1800rpm all the way to 5000rpm. Mid-range urge is prodigious, and Aston claims the DBS Superleggera will blast from 80-160km/h (in fourth gear) in 4.2 seconds. That’s a number I didn’t verify, but I’m not going to doubt it.

It might share essentially the same bonded aluminium chassis, but thanks to its carbon-rich bodywork the DBS Superleggera is 72kg lighter than the DB11, with a ‘dry’ weight (no fluids) of 1693kg. The engine is also set low and far back in the chassis, to the point where it’s actually a front-mid location, delivering a 51/49 front/rear weight distribution.

Suspension is double (forged alloy) wishbone front, multi-link rear, with adaptive damping standard, and there are three set-up stages available via the flick of a switch on the left-hand side of the steering wheel.

On the opposite side of the wheel a similar mode control allows you to cycle through ‘GT’, ‘Sport’, and ‘Sport Plus’ settings, tuning various functions including the throttle map, exhaust valves, steering, traction control, and shift response. Steering is speed-dependent electrically-assisted.

Brakes are professional grade vented carbon ceramics, with thumping 410mm rotors at the front clamped by six-piston calipers, and 360mm discs at the rear sporting four piston calipers.

Managing this car’s phenomenal thrust as it morphs into lateral g-force, is a surprising experience. Of course, it grips like a Trump handshake, with a specific ‘A7’ version of Pirelli’s ultra-high performance P Zero tyre on a 21-inch forged alloy rim at each corner.

The 265/35s at the front are big, and monstrous 305/30s at the rear deliver a strong mechanical connection with the road. But it’s the car’s steering and overall agility that’s unexpected.

It doesn’t feel like a beefy 2+2 GT. And while it’s not in the 911’s league when it comes to response and dynamic feedback, it’s a long way down that road.

I found Sport and the middle suspension setting to be the backroad sweet spot, and with the seven-speed auto in manual mode the lightweight DBS simply lights up.

Shifts on the way up the ratios via proper alloy paddles in manual mode are rapid and precise, and the car remains stable and balanced, yet entertainingly athletic in enthusiastic cornering.

When squeezed hard on initial application carbon ceramic brakes don’t ‘bite’ in the same way steel discs do, but the system’s ability to rapidly wash off speed, while the car remains in a steady state, is exceptional.

At the same time, shifts down through the gears are accompanied by a variety of aggressive pops and bangs (a feature of Sport and Sport Plus modes) and the DBS points accurately yet progressively into a bend.

Road feel is excellent, the sports front seat is grippy and comfortable, and the car’s ‘Dynamic Torque Vectoring’ (via braking) system chips in to ensure understeer is kept in check.

In a more sedate mode, thanks largely to the active dampers, the Superleggera is surprisingly comfortable around town, despite the big rims and low-profile rubber.

Under the heading of ‘random thoughts’, the simple interior layout (including the spot-on digital instrument cluster) is great, the auto stop-start is a little jerky on restart, and including the front air dam, ground clearance under the nose is only 90mm, so be mega-careful in and out of driveways, or prepare yourself for the sound of scraping carbon (happily avoided this time around).

The Aston Martin DBS hasn’t been assessed by ANCAP or Euro NCAP, but the ‘expected’ array of active safety tech is in place including ABS, EBD, and BA, as well as traction and stability controls.

There’s also blind spot monitoring, a tyre pressure monitoring system, a 360-degree camera with ‘Parking Distance Display’ and ‘Park Assist.’

But more recent crash-avoidance tech like active cruise control, lane-departure warning, rear cross-traffic alert, and most notably, AEB, are missing in action.

If an impact is unavoidable there are eight airbags to help protect you - dual-stage driver and front passenger, front side (pelvis and thorax), front knee, as well as two-row curtain.

Both rear-seat positions offer top tethers and ISOFIX anchors for secure baby-capsule or child-seat location.

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.

In Australia, Aston Martin offers a three-year/unlimited km warranty, with 24-hour roadside assistance included for the duration.

Servicing is recommended every 12 months or 16,000km, whichever comes first.

Aston also offers extended service contract options, renewable after 12 months, including features like transfers and accommodation in the event of a breakdown, and coverage while the car is being used at official Aston Martin events.

There’s also a collection and delivery service (or courtesy car) to sweeten the servicing deal.
