Mercedes-Benz CLS-Class vs Alpine A110

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?

Don't let the overall score fool you. The Alpine A110 is an instant classic. While practicality, safety and ownership costs don't set the world on fire, it delivers a driving experience that makes everything right with the world every time you get behind the wheel.

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 final example of the original Alpine A110 rolled out of the Dieppe plant in 1977, and despite more than four decades separating it from this newcomer, the 2019 A110 is effectively a new-generation version.

Much more than a tip of the hat to a special predecessor, the new A110 perfectly updates the distinctive, purposeful look of its not-so-ancient ancestor.

In fact, head of the A110 design team, Antony Villain says, "We wondered; if the A110 never went away, if this new car was the sixth or seventh generation A110, what would it look like?"

Appropriately finished in a very French shade of 'Alpine Blue', our test example was one of 60 'Australian Premiere Edition' cars, and the design is full of intriguing details.

At just under 4.2m long, 1.8m wide, and only a touch over 1.2m high the two-seat A110 is compact to say the least.

It's raked LED headlights and round fog lights are recessed into the markedly curved nose in a complete and unabashed reload, with circular LED DRLs accentuating the throwback effect.

The overall look of the carefully scalloped bonnet is also familiar, with a huge under-bumper grille and side ducts creating an air curtain along the front wheel wells to finish off the treatment with a focused, technical touch.

A steeply raked windscreen runs up to a small turret with a broad channel running down its entre, and the flanks are narrowed by a lengthy, aero-influenced indent.

A case study in tightly wrapped surfacing, the rear-end is equally taut, with elements like 'X-shaped' LED tail-lights, tightly curved rear screen, single central exhaust outlet and aggressive diffuser continuing the expressive design theme.

Aero efficiency is a major influence, and as well as the diffuser careful inspection of the rear side window reveals a neat duct at its trailing-edge funnelling air to the mid/rear-mounted engine, and the underbody is smoothed near flat. An overall drag co-efficient of 0.32 is impressive for such a small car.

The A110 also proudly wears its French heart on its sleeve, with an enamel version of Le Tricolore attached to the C-pillar (and various points around the interior).

Eighteen-inch Otto Fuchs forged alloy rims fit the car's style and proportions perfectly with body-colour matching blue brake calipers poking through the delicate split-spoke design.

The interior is all business with racy Sabelt one-piece bucket seats setting the tone. Trimmed in a combination of quilted leather and microfibre (which extends to the doors) they are separated by a floating, flying buttress-style console housing key controls above and a storage tray (including multi-media inputs) below.

Highlights include cool body-colour panels in the doors, a Ferrari-like push-button gear selection set-up, slender alloy manual shift paddles attached to the steering column (not the wheel), matt carbon-fibre accents on the console and around the circular air vents, and a 10.0-inch TFT digital instrument cluster (which morphs to suit Normal, Sport or Track modes).

The A110's chassis and body are made from aluminium, with a brushed form of that material adorning everything from the pedals and perforated passenger footrest to multiple dash trim pieces.

Quality and attention to detail is outstanding to the point that just getting in the car feels like a special occasion. Every time.

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.

Practicality is the oil to a two-seat sports car's water. If you want day-to-day functionality, look elsewhere. Quite rightly, the Alpine A110 puts driver engagement at the top of the priority list.

That said, with limited real estate to work with the car's development team has made it liveable, with a surprising amount of boot space included, and modest storage options snuck in around the cabin.

The heavily-bolstered, high-sided sports seats, necessitate use of the 'one hand on the A-pillar and swing in/out' technique for entry and exit, which won't suit everyone. And once inside several things are missing.

Glove box? No. If you need to refer to the owner's manual or grab the service book, they're housed in a small satchel attached to the bulkhead behind the driver's seat.

Door pockets? Forget it. Cupholders? Well, there's one, it's tiny, and located between the seats where only a double-joined circus contortionist could reach it.

There is a long storage bin under the centre console, which is helpful, although it's hard to reach in and actually extract things placed in it. Media inputs run to two USBs, an 'aux-in' and an SD card slot, but their location at the front of that lower storage area is tricky, and there's a 12-volt outlet just in front of the unreachable cupholder.

However, if you and a passenger want to head off on a weekend road trip, amazingly, you can take some luggage with you. With the engine located between the axles there's room for a 96-litre boot at the front and a 100-litre boot at the rear.

We managed to fit the middle (68-litre) hard suitcase from our three-piece set (35, 68 and 105 litres) in the broad but relatively shallow front boot, while the wider, deeper, but shorter rear boot is best for soft bags.

Another missing item is a spare tyre, with a neatly packaged repair/inflator kit your only option in the case of a puncture.

At $106,500 before on-road costs the Alpine A110 Australian Premiere Edition competes with an interesting range of similarly specified lightweight two-seaters.

The first that springs to mind is the achingly beautiful, mid-engine Alfa Romeo 4C Coupe at $89,000. For some, its exotic carbon chassis is underpinned by a too-firm suspension and the unassisted steering is difficult to deal with. For others (including me) it offers an exceptionally pure driving experience (and those that can't cop its physical nature need to harden up).

Lotus founder Colin Chapman's engineering philosophy, "Simplify, then add lightness" is alive and well in the form of the Lotus Elise Cup 250 ($107,990), and less than $10k more than the A110's MRRP delivers access to Porsche's thoroughbred 718 Cayman ($114,900).

Of course, part of the A110's substantial price tag relates to its all-alloy construction and the low-volume production techniques required to execute it. Not to mention development of an all-new design and global kick-start of a respected but dormant brand.

So, it's not all about bells and whistles, but for the record, a breakdown of this lightweight screamer's standard equipment list includes: 18-inch forged alloy rims, an 'Active-valve' sports exhaust system (with engine noise aligned to drive mode and speed), brushed aluminium pedal covers and passenger footrest, leather-trimmed Sabelt one-piece sports seats, auto LED headlights, satellite navigation, climate control air, cruise control, rear parking sensors, and electric heated, folding wing mirrors.

The 'Alpine Telemetrics' driving data system provides (and stores) real-time performance metrics including power, torque, temperatures, and turbo pressure, as well as lap times for track day warriors. And you'll also pick up a leather and microfibre-trimmed sports steering wheel (complete with 12 o'clock marker and Alpine Blue topstitching), stainless steel door sills with Alpine branding, dynamic (scrolling) indicators, auto rain-sensing wipers, and a 7.0-inch multimedia touchscreen including 'MySpin' mobile phone connectivity (with smartphone mirroring).

Audio comes from French specialist Focal, and although there are only four speakers, they're special. The main (165mm) speakers in the doors use a flax cone structure (flax sheet sandwiched between two glass fibre layers) and (35mm) aluminium/magnesium inverted dome tweeters sit at either end of the dashtop.

Certainly enough to be going on with, but at more than $100k we'd expect to see a reversing camera (more on that later), and the latest safety tech (more on that later, too).

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 Alpine A110's (M5P) all-alloy 1.8-litre turbo-petrol four-cylinder engine is closely related to the unit found under the bonnet of the Renault Megane R.S.

Alpine has modified the intake manifold, exhaust and overall calibration, but the big difference here is that although it's still transversely mounted, in the Alpine the engine sits in a mid/rear position and drives the rear wheels (rather than in the R.S.'s nose driving the fronts).

Featuring direct injection and a single turbo it produces 185kW at 6000rpm, and 320Nm of torque from 2000-5000rpm, compared to 205kW/390Nm in the Megane R.S. But the Alpine's 356kg weight advantage means it boasts a 169kW/tonne power-to-weight ratio, while the Megane sits at 141kW/tonne.

Drive goes to a Getrag-sourced seven-speed (wet) dual-clutch auto transmission, with Alpine-specific ratios inside.

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 6.2L/100km, the 1.8-litre four emitting 137g/km of CO2 in the process.

Over close to 400km worth of often 'enthusiastic' driving, taking in city, suburban and freeway running we recorded an average of 9.6L/100km.

Definitely a miss, but not bad when you consider we hit the off switch for the standard stop-start system on a consistent basis and regularly took advantage of the accelerator pedal's ability to move towards the floor.

Minimum fuel requirement is 95 RON premium unleaded, and you'll need just 45 litres of it to fill the tank.

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.

Weighing at just 1094kg (target weight was 1100kg), with a 44:56 front-to-rear weight distribution, the all-aluminium A110 is every millimetre the mini-supercar you'd hope it to be.

It only takes two to three rotations of the Alpine's wheels to realise it's exceptional. The Sabelt seat is superb, the chunky steering wheel perfect, and the engine instantly eager to get on with it.

The electro-mechanical power-assisted steering feels just right from the first corner. The rack is quick and road feel is intimate without the crashy feedback penalty paid by the Alfa 4C.

Engage launch control and you're blasting from 0-100km/h 4.5sec, with the engine adding a suitably raucous backing track, a full charge of air rasping through the inlet manifold just behind your ears. Spinning up to the close to 7000rpm rev ceiling is pure pleasure, with peak torque available from just 2000rpm all the way to five grand.

Pressing the wheel-mounted 'Sport' button sharpens gearshifts and holds low ratios for longer, with the already slick dual-clutch really getting its race face on. Hold in the down lever in manual mode and the transmission will instantly shift through to the lowest gear engine revs will allow, the Active-valve sports exhaust chipping in with rude pops and bangs on the over-run. 'Track' mode is even more hardcore, allowing a greater element of slip in cornering. Brilliant.

The engine's mid/rear location delivers a low roll-centre and the double wishbone suspension set-up (front and rear) manages to combine super-sharp dynamic response with a surprisingly civilised ride.

Alpine says the A110's light weight and ultra-rigid chassis mean its coil springs can be reasonably soft and anti-roll bars light so even our truly ordinary urban blacktop doesn't cause too much distress.

The A110 is beautifully balanced, amazingly agile, and satisfyingly precise. Weight transfer in quick cornering is managed to perfection, the car remaining stable, predictable and hugely entertaining.

Grip from the Michelin Pilot Sport 4 rubber (205/40 fr - 235/40 rr) is tenacious, and the torque vectoring system (by braking) quietly keeps things pointing in the right direction if an over-zealous pilot begins to overstep the mark.

Despite the A110's modest kerb weight braking is professional grade. Brembo provides ventilated 320mm rotors (front and rear) with four-piston alloy calipers at the front and single-piston floating calipers at the rear. They're progressive, powerful and consistent.

The only downsides are a clumsy multimedia interface, and the annoying lack of a reversing camera. But who cares, this car is amazing.

In terms of active safety, the A110's sheer dynamic ability will help you avoid an unfortunate incident, and specific tech includes ABS, EBA, traction control, stability control (disconnectable), cruise control (with speed limitation) and hill-start assist.

But forget about higher order systems like AEB, lane keeping assistance, blind spot monitoring, cross traffic alert or adaptive cruise.

And when it comes to passive safety you're protected by an airbag for the driver and one for the passenger. That's it. Weight-saving, eh? What can you do?

The Alpine A110 hasn't been assessed for safety performance by ANCAP or EuroNCAP.

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.

The Alpine A10 is covered by a three-year/100,000km warranty with a twist. According to Alpine, the first two years are covered for unlimited kilometres. And if at the end of the second year total kilometres remain less than 100,000, the warranty continues into a third year (still to an overall cap of 100,000km).

So, you can sail over the 100,000km mark in the warranty's first two years, but that means you won't get a third.

Complimentary roadside-assist is provided for 12 months, continuing for up to four years if your Alpine is regularly serviced at an authorised dealer.

There are currently three dealers only – one each in Melbourne, Sydney and Brisbane – and service is recommended every 12 months/20,000km, with the first two costing $530 each, and the third ramping up to $1280.

You'll also need to factor in a pollen filter ($89) at two years/20,000km and accessory belt replacement ($319) at four years/60,000km.
