Mercedes-Benz Cle53 vs Audi A8

What's the difference?

The AMG CLE 53 4Matic+ is formidable yet friendly, ferocious yet refined and fun yet functional.

Yes, the price is edging up to previous 63 flagship levels, and it can become a bit noisy inside, but the four-seater coupe’s specification, speed, sophistication and balance are compelling reasons to consider this if your shortlist also includes an Audi RS5 or BMW M4.

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

The Audi A8 swims in a luxury car shark tank where those paying the big dollars expect top-shelf everything. It delivers a serene driving experience whether you’re in the front or the back, in a superbly engineered and executed luxury sedan package. Not perfect, but very, very impressive.

Crisp and aero clean with a handsome fastback silhouette, the CLE’s design is very much in the mould of a modern-day C-Class coupe, but with larger proportions in line with what a contemporary E-Class coupe would look like.

It employs the same architecture as the W205 C-Class and W214 E-Class sedans.

Length, width, height and wheelbase measurements are 4850mm, 1861mm, 1423mm and 2865mm, respectively.

Wearing the AMG suffix means the CLE 53’s body differs in small but important ways to the regular C236 coupes.

The front end, for instance, adopts what Mercedes calls a ‘shark nose’ look, for a suitably more macho visage, with vertical slats in the grille and larger air intakes that ultimately aid cooling and performance.

Meanwhile, the tracks are broader by 61mm at the front and 45mm at the rear, and are matched by mudguards that are 58mm and 75mm wider, respectively. This certainly gives the AMG a hunky appearance.

Speaking of which, further AMG visual titivations include a discernibly larger bulge on the bonnet feeding into (functional) side air vents, along with 20-inch specific alloy wheels, as well as a 'Night Package' I and II, comprising black trim elements all around.

A model-specific wider body kit, lip spoiler, twin pairs of tailpipes, diffuser insert and 20-inch AMG alloy wheels complete the CLE’s gymnasium makeover.

Result? The sleek and muscular body’s extra girth, fatter footwear and darkened highlights make the 53 look as menacing as any AMG forbear, setting a very high bar for the CLE 63 to beat when it eventually surfaces. Great work, Affalterbach!

The A8 is close to 5.2 metres long, yet instantly recognisable as an Audi thanks mainly to its evenly weighted proportions, gently curved roofline and overall high-waisted design. Worth noting its drag coefficient (Cd) is an impressively slippery 0.25.

The characteristic look is accentuated by the brand’s signature, six-sided grille, in this instance highlighted by a matrix of high-relief chrome accents. And typically angular LED Matrix headlights sit either side.

Check out our video review for the carefully orchestrated animation they run through when the car is unlocked.

The car looks equally svelte and contemporary from the rear, with just the right amount of chrome lifting the tone and multi-spoke 20-inch rims filling the wheel arches nicely.

As you’d expect, the top-shelf look and feel continues inside with the seats trimmed in aniline leather, perforated on the front and outer rear positions, with genuine hide also covering the centre console, door rails and armrests, steering wheel and upper dashboard.

Fine grain ash wood inserts sit alongside brushed metal elements and a meticulous attention to detail is obvious… everywhere.

For example, the interior door handle design has been thoroughly thought through, requiring a simple underhand tap to open the door, rather than the more conventional, and ergonomically convoluted, ‘over the top’ movement.

Three sleek screens dial up the tech - a 10.1-inch multimedia interface at the top of the centre stack, an 8.6-inch display below it for heating and ventilation, and a 12.3-inch version of Audi’s ‘Virtual Cockpit’ in the instrument binnacle.

And the spacious rear is the epitome of cool, calm Teutonic form and function. You feel relaxed the moment you get in, and isn’t that the primary aim of a car like this?

The interior dons a C-Class-in-drag-race do-over. Frankly, the latest – and much more modern-looking – E-Class sedan’s dashboard would have been preferable, however, given its tech-heavy panorama of screens.

For its AMG 53 outing, the cabin boasts an AMG-specific steering wheel with performance mode knobs, a 12.3-inch driver display brandishing a variety of instrumentation styles (including 'Race', 'Sport', 'Classic' and minimal screens) and a multimedia system with track telemetry data within a tablet-style 11.9-inch touchscreen.

There's also electric and heated ‘integral’ sports seats with memory, 'Anthracite' trim elements set against high gloss black inserts, 64 questionable shades of ambient lighting and banging Burmester premium audio with no fewer than 17 speakers.

This is a roomy and well-presented cabin, offering space to spread out up front, a superb driving position, exceptional seat support, quality materials and a decent level of practicality.

Storage is plentiful, most switchgear is within easy reach and the multimedia system is easy to fathom after you’ve taken the time to familiarise yourself with it.

On the other hand, the glossy plastics do not look or feel as elevated as, say, a Porsche’s interior, the air vents feel flimsy to the touch, while trim squeaks were occasionally heard over some rougher road surfaces. It’s not as solid as you’d expect from a Mercedes at this price point.

Rear access is tight due to a slim aperture, as almost all coupes are, but once sat on the contoured rear bucket seats, most adults should find it tolerable unless they’re especially long-legged or over 185cm or so tall.

Further back, a handy 410-litre boot is provided, with a folding rear seat backrest to boost cargo capacity even further, underlying the CLE’s family-friendly packaging.

Note, though, that this is 10L shy of the regular non-AMG models, and smaller than the Audi RS5 (465L) or BMW M4's (440L) boot.

Plus, no spare wheel is available – just a tyre repair kit.

Space is luxury, be it a large house, a first class seat or a spacious car, and at nearly 5.2 metres long with a close to 3.0m wheelbase the Audi A8 measures up. 

Even before you get in, the doors have an amazing sense of solidity and quality. It’s like opening and closing a bank vault… if that huge circular door had a power-assisted soft-close function. 

There’s copious amounts of space for the driver and front passenger with lots of storage including a lidded box between the front seats, complete with a two-piece longitudinally split top design, so you can sneak your half’s open without displacing your neighbour’s elbow.

The door bins are decent but there isn’t a specific cut-out for bottles, so it’s more a case of laying them down than standing them up. There’s also a handy covered cubby at the end of the door armrests.   

The glove box is a good size and there are two cupholders under a pop-up cover in the centre console.

Of course, the back is where space really counts, and there’s as much room as you’d find in, well… a limo.

Sitting behind the driver’s seat, set for my 183cm position, I enjoyed copious amounts of head, shoulder and legroom. 

There are electric sunblinds for the rear and rear side windows, controlled by buttons in the door as well as the rear seat remote, a 5.7 inch OLED display housed in the beautifully trimmed fold-down centre armrest (which also has a soft close function!). The remote also allows adjustment of the lighting and climate control. Classy.

There’s a shallow storage box and twin cupholders in the armrest, medium size door bins and hard shell pockets on the front seat backs. The rear armrests also feature a small lidded cubby. 

In terms of connectivity and power options there’s wireless Android Auto and Apple CarPlay, a USB-A and USB-C in the front, and an identical pair in the rear, as well as a 12-volt socket in the front and two in the back.

Boot volume is a useful 505 litres (VDA) and the lid is electric, with gesture control. It’s able to easily swallow our three-piece luggage set or the bulky CarsGuide pram. And while the rear seats don’t fold there’s a ski port door to accommodate long items. Just make sure you use the tie-down anchors in the boot to ensure they’re properly secured. There’s a handy netted section behind the left wheel well and a cargo net is included.

Maximum towing capacity, for a braked trailer, is 2.3 tonnes (750kg unbraked) and in more good news, the spare is a space-saver rather than the increasingly prevalent inflator/repair kit.

With an entry price of $202,700, before on-road costs, the A8 is in the thick of it amongst its full-size primo sedan competitors from Europe and Japan. Specifically, BMW’s 740i MHEV ($272,900), the Lexus LS500h ($195,920), Maserati Quattroporte GT ($210,990), Mercedes-Benz S450 ($244,700) and Porsche’s Panamera ($207,800).

By definition, a luxury car should be loaded to the gunwales with features that make life on the road that little bit easier. And aside from the performance and safety tech we’ll cover shortly, the highlights from a very lengthy standard equipment list are - 20-inch alloy rims, metallic paint, adaptive cruise control, digital matrix LED headlights, digital OLED tail-lights, full keyless entry and start, power-assisted door closing, power boot lid (with gesture control), a panoramic sunroof, heated, ventilated and massaging electrically adjustable front seats, heated front armrests and extended leather trim (centre console, door rails and armrests, steering wheel and upper dashboard).

Also included are ambient interior lighting (with 30 colours and six colour profiles), four-zone climate control, electric sunblinds for the rear and rear side windows, ‘Audi Connect’ navigation and multimedia (with voice and handwriting recognition), wireless Android Auto and Apple CarPlay, 17-speaker 730-watt Bang & Olufsen audio (with digital radio) and a colour head-up display.

There’s a lot more, and the A8 can hold its head high in terms of pricing and features relative to its $200K price tag and the competition.

Under the bonnet is a 3.0-litre, in-line, six-cylinder petrol engine. Mercedes-AMG calls it “double charged”, with a single, 1.5-bar turbo augmented with an electric compressor as part of a 48-volt Integrated Starter Generator (or ISG).

The latter makes 17kW of power and 205Nm of torque, for a system total of 330kW at 6100rpm and 560Nm from 2200-5000rpm. Up to 600Nm is possible thanks to a 12-second overboost.

It also recuperates brake energy, offers “almost imperceptible” stop/start fuel saving and allows for an off-throttle, engine-off ‘sailing’ mode.

Not interested in economy? Tipping the scales at a hefty 2015kg the CLE 53’s power-to-weight ratio is a sparkling 164kW/tonne.

All Australian-bound CLE 53s feature the Dynamic Plus Package, with a launch-control function that helps deliver an eager 0-100km/h sprint time of 4.0 seconds. Top speed is governed to 250km/h.

Drive is sent to all four wheels via a nine-speed torque converter automatic transmission. It can simulate double-declutching and offers variable shift modes according to drive settings.

The AWD system, meanwhile, varies torque from 50:50 front/rear to 100 per cent rearwards.

To aid handling, the 4WS system allows the rear wheels to turn in the opposite direction to the fronts, up to 2.5 degrees at up to 100km/h, and 0.7 degrees in unison with the fronts above that speed.

Keeping things in control is a four-link front and five-link independent rear suspension set-up, with AMG ride control featuring adjustable dampers and sports spring rates.

The Audi A8 50TDI is powered by a 3.0-litre turbo-diesel V6 engine sending 210kW (from 3500-4000rpm) and 600Nm (from 1750-3250rpm) to all four wheels via an eight-speed automatic transmission (with ‘Tiptronic’ sequential manual shift function) and Audi’s quattro constant all-wheel drive system using a self-locking centre differential.

It also features a 48-volt electrical set-up for mild hybrid functionality built around a belt connected starter/generator, AC to DC converter and a 48-volt lithium-ion battery. 

With energy recovery of up to 12kW from regenerative braking, it enables the A8 to regularly coast with the engine switched off and helps the extended stop-start system to operate smoothly. 

Considering the performance on offer, the CLE 53’s 9.6 litres per 100km combined (urban/extra-urban) cycle fuel consumption rating is not too bad. That equates to a carbon-dioxide emissions figure of 219 grams/km. City/highway numbers are 13.2 and 7.6L/100km.

With a 65-litre fuel tank filled with 98 RON premium unleaded petrol, expect an average range of about 685km.

What did we achieve? Driven fairly hard on some of Tasmania’s most beautiful rural roads, the trip meter showed an indicated 9.5L/100km.

Audi’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.6L/100km, the 3.0-litre turbo-diesel V6 emitting 175g/km of CO2 in the process.

Over a week of city, suburban, and some freeway running we averaged 11.1L/100km, which is acceptable for a 2.1-tonne luxury sedan.

Also worth noting the standard stop-start system works beautifully thanks to the 48-volt starter/generator.

You’ll need 82 litres of diesel to fill the tank and using the official number, that translates to a range of just over 1240km, which drops to around 740km using our real-world figure.

The new AMG CLE 53 might look much like several of its AMG 63 predecessors, with its brutish stance and bulging bits, but does the German performance coupe drive and feel like an AMG flagship?

With a 63 range-topper (as yet unconfirmed) in the pipeline, that’s a bit of a moot point here, because that will be an altogether harder, faster and more expensive proposition.

But we can tell you that, even without the bellowing V8 of old, the 53 does a damn-fine impression of a charming high-performance GT with the straight-six .

At the heart of the matter is the inline six-cylinder turbo-petrol engine incorporating an electric compressor working the lower revs for punchy off-the-line acceleration and a big twin-scroll gas turbo for more-instantaneous responses further up the rev range.

This makes for an impressively rapid real-world tearaway. Not brutally fast in the way even middling EVs can manage to be nowadays, but still with an urge and character that puts you in the mood for speed.

The steering, meanwhile, is alert, faithful and remarkably reactive, with that 4WS rear end tucking in neatly through the tight turns and twisty bits, allowing a feverish pace with a pleasing grace to be maintained.

Assisting that immersive agility is an almost unshakable sense of grip – no surprise given the variable-torque AWD as well as the late-summer warmth and dryness of the roads we were testing on.

Yet, even beyond these factors, it’s clear the AMG’s immense roadholding provides a reassuring layer of confidence and control.

No opportunity was provided to unleash the CLE 53’s full fury on a track, so we can’t tell you how easily sideways or catchable this thing steers in Race mode with all the safeties turned off, but this coupe’s dynamic bandwidth was obvious during the all-too-few occasions we did manage to fang it.

Another positive is the suspension’s ability to soak up the bumps without too much disturbance inside, allowing for easy and effortless cross-country touring. No truly terrible roads were encountered during our half-day in this civilised beast, though, so we’ll have to reserve our judgement on whether this is the comfortable all-rounder that Mercedes claims it is.

What we can tell you is that there is too much road-noise intrusion inside an otherwise isolated cabin. And we’re no fans of the lack of a spare wheel – an absolute necessity in Australia.

Still, first impressions are very positive.

Its maker calls the CLE 53 the AMG for all occasions, and we cannot argue with this logic.

That there’s a decent wad of thrills and emotion on offer to counterbalance this car’s comparative refinement and civility just proves there is a place for the penultimate version of this series.

Despite extensive use of aluminium in the ‘ASF’ platform and body panels, the A8 tips the scales at a sturdy 2095kg, yet Audi says the A8 will accelerate from 0-100km/h in just 5.9 seconds. And with 600Nm of peak torque available across a flat plateau from 1750-3250rpm this big four-door gets up and goes hard when asked to. 

At more sedate speeds you’re occasionally reminded there’s a diesel engine under the bonnet, with that characteristic engine and exhaust noise only making their presence felt under pressure. 

In fact, under normal circumstances, noise, be it the engine, tyres or wind is minimal, thanks to a combination of the car’s aero-efficient shape, thick acoustic glass and other sound-deadening measures throughout the car.

The eight-speed auto transmission is suitably smooth, with the central shifter or wheel-mounted paddles able to make snappy sequential ‘manual’ shifts.

There are four drive modes in the ‘Drive Select’ system - ‘Comfort’, ‘Auto’, ‘Dynamic’ and ‘Individual’ - enabling tweaks to the steering, transmission, throttle and suspension. Comfort felt most appropriate most of the time, although dialling up the throttle and transmission to more aggressive modes in Individual adds an enjoyable edge.

The suspension is five-link front and rear with an adaptive air system smoothing even high-frequency bumps and ruts amazingly well.

Push into a corner and the A8 feels nicely balanced, its wide track, sophisticated suspension, plus the quattro AWD system seamlessly distributing drive between the front and rear axles, keeping the big body under control. In fact, you feel the ‘big car shrinking around you’ syndrome from the get-go.

The steering is precise without being overly sharp and road feel is good. Again, with that 2.1-tonne kerb weight in mind, braking is appropriately powerful with big ventilated discs front (350mm) and rear (330mm).

It pays to remember the turning circle is 12.5m, and it’s worth picking your spot for a U- or three-point turn.

Although there’s a lot going on for the driver in terms of screens, buttons and switches it all makes sense ergonomically. The head-up display is helpful and there’s a common sense mix of digital and physical controls, the latter including an audio volume knob. Yes.

Even though the A8 hasn't been assessed by ANCAP, as you might expect, it goes to town when it comes to active safety tech, the car’s standard crash-avoidance features including auto emergency braking (AEB) (pedestrians/cyclists - 5.0-85km/h, vehicles - to 250km/h), ‘Active Lane Assist’, blind-spot monitoring, a reversing camera and 360-degree view (including kerb view function), front and rear parking sensors, ‘Collision Avoidance Assist’ (steering assistance in critical situations), ‘Turn Assist’ (monitors incoming traffic when turning right), and rear cross-traffic alert. 

There’s also ‘Intersection Crossing Assist’, ‘Attention Assist’, tyre-pressure monitoring and an ‘Exit Warning System’ (detects cars and cyclists when opening doors). 

If all that isn’t enough to avoid a crash the airbag count runs to nine, including front and side bags for the driver and front passenger, side airbags covering the outer rear passengers, full length curtains and a front centre airbag to minimise head clash injuries in a side impact. A first aid kit, warning triangle and high visibility vests are also on-board.

There are three top tethers for baby capsules/child seats across the back seat with ISOFIX anchors on the outer positions. 

Somewhat average for most mainstream and luxury brands, Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance.

Intervals are every 12 months or 25,000km, and while no capped priced servicing is offered, pre-paid three-, four- or five-year service plans are available, ranging from $4190, $5310 and $7760, respectively at the time of publishing.

The A8 is covered by Audi Australia’s five-year/unlimited km warranty, which is now par for the luxury market course, and 24-hour roadside assistance is included for the duration.

Paint defects are also covered for five years, with rust (to the point of perforation) covered for 12. Nice.

Service is required every 12 months or 15,000km with a five-year capped-price plan for the A8 coming in at $3830, or $766 per year. That’s a fair wedge but not outrageous for the category.
