Mercedes-Benz G63 vs Ford Tourneo Custom

What's the difference?

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

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.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

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 G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

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.

The G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

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.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

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.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.

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.
