Mercedes-Benz AMG GT vs Ford Tourneo Custom

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.

There’s absolutely no doubt that the van-based people-mover has some distinct advantages over a three-row SUV. The rear seat is bigger, access to it is far better and there’s more luggage space even when all eight seats are occupied. But the Tourneo goes a step or two further with the sliding, swivelling seats that make it one of the most practical and flexible interiors on the market.

True, the driving experience is a bit alien at first, but it’s a case of different, rather than worse. Meantime, the ride is excellent and the performance and economy from the turbo-diesel driveline are both absolutely spot on for this vehicle’s intended purpose.

And perhaps that’s the metaphor for the whole thing: By not trying to be something it’s not, and concentrating on what it needs to do, the Tourneo emerges as a bit of a quiet achiever.

As we said earlier, this type of vehicle concept is never a sure-fire proposition. Parcel vans converted to passenger duties haven’t always worked out. This time, though, it’s different.

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.

Perhaps the biggest revision of the successful Transit Custom formula needed to make the leap from FedEx to Brady Bunch has been to the rear suspension. Where the Transit uses a leaf-sprung arrangement, the Tourneo has switched to coil rear springs. These technically offer much greater ride comfort at the expense of some load-carrying ability. Which is fine, even if your kids are the bigger variety.

The move to powered sliding side doors is a welcome one, but I found out the hard way that the doors will still open a fraction if you push the button while still travelling at low speed. Not sure why that would be, but at least the buttons in question are up front in Adult-Land, not within reach of you-know-who.

The reality is, too, that the Tourneo is destined to run with the air-con on any time you have bodes in the back. That’s because – like a lot of van conversions – there’s no opening side windows beyond the tiny, hinged windows that open an equally tiny amount. This has more to do with the Transit’s basic structure than any desire to oxygen-deprive the young `uns, but as any parent knows, a supply of fresh air on the move is sometimes the only thing between a happy day out and a clean up in Aisle five.

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.

Here’s where a vehicle like this stands or falls. Because if something like a Tourneo can’t cope with lots of people and their luggage in a single bound, then there’s really not much point to it, is there? I mean you’re not going to buy it for its sporty looks or supercar dynamics, so unless it works brilliantly as family transport, it’s kind of dead in the water. Fortunately Ford seems to have got it right. Mostly, anyway.

That starts up front where the two front seats feel like they’re metres apart. In reality, this huge gap forms a walk-through function for getting access to anything or anyone misbehaving in the second or third row of chairs. But you can’t help wondering what if… What if Ford had ditched the stubby centre console and added a third front-row seat? Wouldn’t a nine-seater be better than eight?

But the seats themselves are comfy and the high-and-mighty driving position gives plenty of vision in every direction. With one exception. And that is when you’re pulling out of a side street on to a main road and need to see what’s coming from the left. Depending on the angle you’re on, the fat frame of the pop-out side window (in the sliding door) becomes a blind spot, especially for taller drivers.

There’s nothing irretrievably wrong with the way the controls are laid out, but they will take some acclimatisation. That goes for the menu system on the touchscreen as well as the column-mounted shifter wand which is about the same size and shape (and in the same place) as a conventional indicator stalk. Tip the lever accidentally and you’ll wind up in neutral, wondering what just happened. The manual-shift mode is also fiddly to use and paddle sifters would be vastly better. Most won’t bother anyway.

The front cabin is home to a shallow lidded bin in the centre console, a deeper bin below that and a couple of charge points. There are also cup-holders in great spots up high in the corner of the dashboard, a shelf across the top of the dashboard and no less than two gloveboxes (the top one is pretty shallow) thanks to moving the passenger’s airbag into the roof lining. Both front doors also feature bins and storage nooks but there’s a fair bit of hard plastic on show, surely a legacy of the Tourneo’s parcel-van DNA.

The Tourneo’s party trick is the way both the second and third rows of seats can be slid to almost any point on a pair of tracks in the floor. The move is simply accomplished via a lever at the front or a rip-cord in the back of the seats, and all three centre-row seats can be moved individually (the third row is split 60:40). The upshot is that you can have all three rows bunched together for a large luggage space, or the rear row pushed right back to form a rear row with huge legroom. Don’t need all eight seats? How about a second row with the two outside chairs in place and the centre one folded forward to expose a work-surface with built-in cupholders.

But it gets even better, because individual seats can be removed to suit the weirdest of loads and the second-row seats even swivel 180-degrees to form a loungeroom on wheels. The kids will be begging you to take them for a drive in this thing.

The seats fold forward, but they don’t tumble. They don’t need to really, and they don’t fold into a bed either. But if you fancy camping in the Tourneo, you can remove both rows of rear seats for a huge flat floor.

The second row is home to storage bins in each sliding door (yes, a door on each side) a pop-put window that opens only about 40mm, temperature controls, air vents and reading lights. The third row, meantime, is not only easily accessed provided the second row isn’t slid all the way back (at which point you wouldn’t be using the third row anyway) but the good news is that the rearmost seat itself is basically three bucket seats with the same comfort levels (high) as the second row. There are also reading lights and a pair of phone pockets and cup-holders in the last row, too. Only the way the track system works and the shape of the seat base means that foot-room is limited to an extent.

With all three rows in place, but pushed as far forward as they can go, there’s a long load area of up to 725mm. But you can also push the second and third rows all the way back and have a cargo area 2622mm long behind the front seats. Maybe the van DNA is a good thing after all.

With all eight seats in place, there’s a minimum of 673 litres of luggage space which can be expanded all the way to a monster 4683 litres with the second and third rows removed.

There’s also a 12-volt power socket and a lighting system in the back, too, although while the side doors are automatic, the tailgate is manual. And you’ll need plenty of real estate to open it, too. Even tall folk will hit the button to open the tailgate, start the strut-assisted opening and then take a step or two back to allow the huge tailgate to rise without clobbering them. An automatic tailgate where you hit the button and run away to a safe distance would be much nicer.

If ever the Average Aussie family has been in the grip of a cost-of-living crisis, it’s right now. With that in mind, we’ve chosen the entry level version of the Tourneo, the Active, for this review. At $65,990 before on-road costs, it’s not exactly cheap, but does come in a full $5000 less than the Titanium X version.

And it is pretty well equipped. That starts with 17-inch alloy wheels, 13-inch touchscreen and 12-inch driver information screen, Bluetooth, full connectivity including wireless Apple CarPlay and Android Auto, wireless charging, 10-speaker stereo, tri-zone climate control, automatic wipers, heated front windscreen, keyless entry and start, 10-way powered driver’s seat, heated and cooled front seats, and a pretty nice artificial leather covering for some of the touch-points.

In a continuation of an industry-wide trend that we wish would stop, only white is considered a standard, no-cost paint colour. Every other colour costs extra, but in 2025, should it?

If the budget will stretch the extra five grand, the Titanium X model adds body coloured bumpers, a 14-speaker stereo, a 360-degree camera system, ambient interior lighting, heated outboard seats in the second row, and extra areas of (better) artificial leather trim.

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.

Because the platform is (mostly) borrowed from the Transit Custom, you get the same driveline. That starts with a 2.0-litre turbo diesel, good for 125kW of power and a useful 390Nm of torque. It drives through a conventional eight-speed automatic transmission and then to the front wheels as a means of keeping the load floor as flat and low as possible.

Ford claims a 2500kg towing capacity with a braked trailer, but on a wet road or damp boat ramp, that’s really going to test the limits of the front wheel’s grip which can be overcome even in the dry if you’re too hasty with the throttle.

The biggest engineering change in the move from Transit Custom to Tourneo has been the switch from leaf springs on the former to coil springs and an independent suspension on the latter. This is all in the name of ride quality and recognises the fact that the Transit will often be called on to cart heavier loads than eight humans.

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.

Ford quotes an official combined fuel consumption figure of 7.4 litres for the Tourneo. Over a few days of running in a pretty broad mix of urban and country work, we saw an average of 8.6 litres per 100km which is still pretty good for a vehicle of this size.

With the standard 70-litre fuel tank, that gives the Tourneo a theoretical combined range of around 900km between fills, but the real-world number says closer to 800km is more realistic.

Don’t forget, either, that running costs will be a little higher than some diesels, as the Tourneo requires AdBlue at regular intervals, in line with its Euro 6 emissions levels.

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.

If you haven’t driven a one-box van for a decade or more, you’re in for a treat. Just like the Transit Custom on which this car is based, the Tourneo represents a different experience to that of a conventional car or SUV, but one that is not without merit.

For a start, you sit very high which means a great view out across the traffic. And while the driving position is a little less laid-back than a modern car, once you get used to the almost square steering wheel, neither is it the dreaded sit-up-and-beg of older van designs.

The four-cylinder engine doesn’t make the Tourneo a fast vehicle, but it does give it lots of flexibility thanks to all that turbo-torque being available from just off idle. The eight-speed transmission helps, too, but the real surprise is just how quiet the Tourneo is when on a cruising setting. In fact, it’s almost uncanny how such a big, empty metal box could be so silent, but beyond a little tyre noise on coarse surfaces, the Ford pulls it off. As a result, it’s very relaxed and effortless feeling at freeway speeds.

The other surprise is how good the ride quality is. By swapping the cargo van’s leaf rear springs for coils, the Tourneo suddenly displays a very good match between the front and rear axles in terms of how they work to absorb bumps. You do still get some of the front-seat sensation that you’re sitting over the front axle, but it’s not terrible and the reality is that you simply sitting closer to the axle, not right over it.

For many drivers perhaps the over-riding impression will be of the vehicle’s external size. And, yes, it’s a long and wide piece of equipment, but at least the boxy shape means the corners are easy to place and the huge glass area and driver aids like parking sensors and blind-spot warnings help a lot in the daily cut and thrust.

Things are also improved by the fabulously small turning circle of 10.9m kerb-to-kerb (courtesy of the Transit’s role as an inner-city delivery van) that gives an agility the looks don’t suggest. But there’s a sense that the Tourneo is a little wider in the rear track than the front, as you’ll sometimes find the inside rear tyre finding the lips of roundabouts and suburban gutters.

Keeping the whole family safe is the name of the game here, so Ford has extended things like side-curtain airbags right through to the third row, thereby covering every outboard seating position. In fact, there are nine airbags all up, including a centre airbag between the front seat occupants.

Driver assistance programs include forward collision warning which incorporates the autonomous emergency braking (AEB) function, blind-spot monitoring and assistance, rear cross-traffic braking, active cruise-control, tyre pressure monitoring, lane-keeping assistance, front and rear parking sensors and traffic sign recognition.

The AEB works at any speed above 5km/h, and the pre-collision assist at speeds above 30km/h.

Both the second and third rows of seats feature a pair of ISOFIX child-restraint mounting points (for a total of four) while there are five top-tether restraint mounting points as well.

The Tourneo hasn’t been locally crash tested as per the safety-stars system, but the Transit Custom has been assessed overseas as part of a commercial van safety comparison which graded the vehicle at 96 per cent, the highest rating ever achieved by a van undertaking the test program in question.

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.

Ford offers its standard five-year/unlimited kilometre warranty on the Tourneo. Five years is fair enough, but can’t match the seven years or even more that some of the competition offer. It‘s worth noting, however, that the warranty does match many of the makes and models that will be the Ford’s natural enemies.

Service intervals are 12 months or a very long 30,000km, but it’s unlikely many families will clock up 30,000km in a 12-month period, anyway. There’s no word on capped-price servicing yet, but the mechanically similar Transit Custom has a service plan that limits the cost of each of the first four services to around $500.

The biggest additional running cost for the Tourneo will be the AdBlue additive to control emissions. How frequently you need to top up will be determined by what type of driving you do.
