Mercedes-Benz AMG GT vs Alpine A110

What's the difference?

The GT63 4Matic+ is a breathtaking example of everything that Mercedes-Benz and AMG are.

Ferociously fast, incredibly agile and superbly sophisticated, it should be on anybody’s shortlist, if that also includes a Porsche, Aston Martin, Maserati or even a Lamborghini. And it’s definitely much more than yesterday’s SLC ever was – for similar money in today’s terms, as it turns out.

But, around Tasmania’s glorious roads at least, the Mercedes-AMG lacks the ride comfort and road noise isolation to be a fully-rounded-out GT, and that’s a disappointment for a brand with such formidable history in making such cars.

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.

This is still clearly a Mercedes AMG GT coupe, like the 2014 C190 original, but a ground-up redesign sees it subtly yet significantly altered.

Some 270kg heavier than before, the larger-in-every-dimension body combines aluminium, steel, magnesium and fibre composite materials for improved rigidity and a lower centre of gravity. Length (4729mm) and wheelbase (2700mm) have been stretched by 177mm and 70mm respectively. Width (1984mm) and height (1352mm) are also up.

The nose treatment is similar to before, especially with the bulgy bonnet and signature vertical slatted grille fitted. These, combined with the LED digital headlight shape effect, is reminiscent of, but far-better executed than, the goofy-looking MG5’s face.

Underneath, it's an all-new platform shared with the SL, with the rear transaxle of the old car replaced by a permanent AWD system, leading from 46:54 front/rear weight distribution to 50:50 as a result.

That aggressive, exaggerated cab-backward/ultra-long bonnet silhouette that visually connected it with the SLS gives way to more-conventional and practical coupe proportions that is striking if not especially original, since they do look quite 911-esque. Along with the longer wheelbase and wider tracks, the result allows for two small rear seats to be fitted, while liftback cargo access remains.

Similarly, in the name of way-more usable interior packaging, Mercedes-AMG says it pushed the driving position nearly 180mm forward compared to the previous GT. Let’s see what that all looks like inside.

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.

The first impression inside is that of space, despite the falling roofline and coupe-like upsweep of the side windows and you look back. While, again, similar to a 911s, a kink at the door gives the GT a unique character.

Even larger people will appreciate the generous amounts of room up front, with space to stretch, sat in sumptuously comfy bucket seats. Note that the standard ones are better than the racier but firmer Sports versions.

The driving position is perfect, ahead of a dashboard that is very typical modern Mercedes in appearance and layout.

To that end, the tablet-style integrated touchscreen (11.9 inches) is clear, fast and intuitive once time is taken to learn it. And points are also won for the multi-configurable electronic instrumentation, that allows for a variety of screens, including track, classic and minimalist views.

The trademark turbine air vents, the quite beautiful material and trim finishes and just the general solid feel are further typical contemporary Mercedes cabin treatments, as are the excellent ventilation and ample storage options.

And while rear vision isn't great, that's what cameras are for. It's all pretty much on brand.

It is a shame, given how elevated the Mercedes-AMG engineering is underneath, that the GT’s interior look and ambience is so similar to those of a (albeit higher-spec) C-Class or GLE. It's simply not as special as some of the company’s previous sports cars.

More annoyingly, the ride is too firm and bumpy for a GT, and this has the unhappy effect of provoking random rattly trim sounds within the cabin. It’s a bit like scrunched-up cellophane. In a $420K (as tested) Merc, that’s very disappointing, especially as it can be heard over the copious amount of road and tyre noise droning through, particularly on coarser bitumen surfaces.

Further back, the rear seat is strictly two-plus-two, and nobody over 150cm tall is recommended to travel there by Mercedes itself. That sloping roofline is the culprit. That said, brief trips with a bowed head are possible, as the fixed cushions and split-folding backrests are actually surprisingly comfy. But only for short journeys. Kids should love it though, and the second row does open up the GT’s usefulness enormously.

As does a near-doubling of the AMG’s cargo capacity, jumping 146 litres to 321L with backrests erect, to a whopping 675L (+325L) in two-seater mode. The flat floor is accessed via a large electrically-operated liftback door, offering quite a large aperture for easy loading/unloading.

Having no spare wheel helps here, with a tyre inflation kit included in lieu of that.

Meanwhile, at the front, under the bonnet, things have definitely changed for the better as well.

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).

There’s a plaque signifying which engineer “handcrafted” the GT’s engine – in this case, the famous M177 in 3982cc, 4.0-litre twin-turbo intercooled V8 petrol guise.

Delivering 430kW of power at 6500rpm and 800Nm of torque from 2500-4500rpm, it sends drive to all four wheels via a nine-speed multi-clutch transmission (dubbed MCT in AMG-speak), catapulting the GT63 4Matic+ from 0-100km/h in just 3.2 seconds, on the way to a top speed of 315km/h.

How does it do that?

With AWD, the GT is now nearly 15 per cent heavier than before, but it still manages a punchy 218kW/tonne. Active aerodynamics over, inside and under a more-rigid body structure also helps.

The AMG 4Matic+ AWD system goes from 50/50 front/rear, to 100 per cent rear, variable torque distribution according to conditions and settings, and backed up by an electronic limited-slip differential. Among the many driving settings are Race Start, Drift Mode and good-old Comfort, if it all becomes too much.

Also keeping all that performance in check is a high-performance composite brake setup with improved cooling for faster responses.

Interlinked active roll bars improve body control, the five-link independent suspension features adaptive dampers for a softer ride.

And, as for that 4WS tech, the rear wheels steer opposite to the fronts at up to 100km/h (by some 2.5 degrees) for tighter and tidier handling, or 0.7 degrees in the same direction above 100, for greater stability and road-holding.

Its effect on the way this near-two-tonne coupe zigs and zags around corners is something you need to experience to really appreciate.

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.

Actually, the GT’s economy isn’t horrendous considering how fast it can go.

Even blasting a few times around beckoning country roads, we managed an indicated 13.0L/100km, which is an improvement on what Mercedes-AMG says the GT averages the 14.6L/100km average that Mercedes-AMG officially states.

That translates to a carbon dioxide emissions rating of 334g/km.

Using 98 RON premium unleaded petrol, an average of just under 480km between refills of the 70L tank is possible. The urban run sees consumption rocket to 21.8L/100km (for just 321km of range), or 10.4 out on the highway run, meaning that over 670km is possible should you decide to drive in a docile manner.

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.

Nobody will drive the GT63 4Matic+ and think, ‘Oh, this is OK’, because its breadth of performance is phenomenal.

No matter which mode you're in, from Comfort through to track-tuned Race, the Mercedes-AMG blends forceful pace and commanding control without ever breaking a sweat.

Flex your right foot and the two-tonne coupe bounds into action like a giant on a mission, striding past posted speed limit signs in nanoseconds and way, way faster than the law will stand if diligence isn’t exercised.

And there’s no point relying on seat-of-your-pants sensations, either, because the chassis below embraces the road with an almost zealous devotion. Which is astounding, given how agile the four-wheel steering-enhanced handling is.

The 63’s super power is exactly that – it dulls your sense of speed. One tester admitted to exceeding 150km/h before noticing. An odd confession considering the sonic boombox that is the bi-turbo V8’s howl.

But jailbait performance is not even the 63’s most lingering joy. That would be its steering perfection, that delivers that rare trifecta of keenness, crispness and communication. The wheel feels eager and alive in your hands, even when powering between tight turns, backed up by sensational grip and control. How can a two-tonne GT handle so sharply?

Warm, dry roads were the order of the day, so we can’t tell you how the 4Matic+ permanent AWD system deals with wet or slippery surfaces, but the slick multi-clutch transmission, seamless torque-vectoring tech and sticky tyres more than cope with the 63’s formidable outputs.

So, that's the gushing part out the way, then.

Despite the adaptive dampers, rigid architecture and exquisitely sophisticated suspension, the ride is simply too stiff in Comfort mode, and downright jittery on some of the Tasmanian roads we tested on, for the 63 to be considered a true luxury grand tourer. It just isn't comfortable, luxurious or supple enough.

Plus, grippy as they are, the 21-inch wheels transmit too much road and tyre noise through to the cabin, meaning that the GT isn't as quiet as you'd hope. Add the aforementioned trim squeaks, and the expected cocooned silence isn’t always there.

The upshot is that the 63 possesses more of a sports car character than a luxury GT character. Great news if you're a 911 type buyer and are seeking a high-performance 2+2 alternative, but a disappointment if comfort and refinement are priorities.

Still, it is impossible not to be deeply moved by this Mercedes-AMG.

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.

What’s the GT like to own?

Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance. This is average for most mainstream and luxury brands, but superior to most sports-car makers like Porsche and Lamborghini.

Intervals are every 12 months or 20,000km, and while no capped-priced servicing is offered on the GT, pre-paid three-, four- or five-year service plans are available, ranging from $5165, $7700 and $8665 respectively.

Big performance demands big maintenance bills, it seems.

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.
