Mercedes-Benz G63 vs Ineos Grenadier

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.

The Ineos Grenadier Quartermaster is best regarded as a charming old-school oddity in an increasingly cookie-cutter dual-cab ute market.

In the same vein as the Suzuki Jimny, Jeep Gladiator, and Toyota LandCruiser 70 Series, this ute is for those of us who really like driving to be a fully immersive experience and don’t mind a few sacrifices and some discomfort along the way.

Good on Ineos for giving it a crack.

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.

The Quartermaster is 5400mm long (with a 3227mm wheelbase), 1943mm wide, and 2019mm high. It has a listed kerb weight of 2718kg and a 14.5m turning circle.

I’m always reluctant to talk about any vehicle’s design but it’s easy with something like this ute.

The Quartermaster has a distinctive look. It’s blocky, hard lines everywhere, and it’s straight up and down, old school.

Substantial side steps/runners, exterior utility belt (a integrated feature by which you can attach accessories, tools, or cargo to the Quartermaster’s exterior), and BFGoodrich All-Terrain KO2 all-terrain tyres on 17-inch alloy wheels add to this ute’s presence.

It certainly catches everyone's attention, for better or worse because some people like it, some people don't. I happen to be part of the mob who actually like the look of the Quartermaster and its sibling, the Grenadier station wagon, and the design pretty much works overall.

Extras like the black contrast roof, safari windows and raised air intake further set this Quartermaster apart from most other modern dual-cab utes on our roads.

The interior is somewhat spartan but well laid-out and comfortable. It has lots of controls and quirky styling to keep everyone inside occupied and while, at first, it’s all a confusion of buttons, knobs and dials, it soon takes on a more familiar feel as you become accustomed to everything.

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.

In terms of practicality, it's pretty good news inside the Quartermaster cabin when you first climb in. As mentioned, there is a confusion of dials, buttons, knobs, everything in front of and above you. But give yourself some time to locate controls and understand how to best use them, and you'll be absolutely fine.

As alluded to in Design, the cabin looks really good but it also functions quite well as a work or travel space. Once you are underway and you have a firm understanding of everything, it all feels comfortably familiar.

There are hard plastic surfaces in the cabin, leather accents, as well as plenty of quirky styling cues around the cabin, including port and starboard markings, aircraft cockpit-style controls and more, and you'll have fun discovering those.

The floor has drain plugs and the buttons and switches have an IP54K rating (protected from limited dust ingress and water spray from any direction) with the idea being that, worst comes to the worst, you can always hose out the interior if it gets really dirty.

The Recaro seats, front and rear, are very comfortable. There's not a whole lot of room in the rear seat. You don't get much leg and knee room, especially if you are tall, but the seats are raised for optimised visibility to the front and otherwise, with big glass everywhere and safari windows, it’s an airy and useable space. 

The auxiliary battery is under the rear seat.

All in all, it's a functional and comfortable interior.

Anyway to the business end. The tub is 1564mm long, 1619mm wide (1137mm between the wheel arches) and 485mm deep. It has a sturdy tub liner, four-tie-down points, a load-space light, power socket.

The full-sized spare was located in the rear left-hand corner of the tub and while that’s not ideal and certainly doesn’t optimise the load space, it can be shifted elsewhere – on the roof perhaps – and it’s not as much of an eye-sore as the spare in the GWM Cannon Alpha PHEV tub.

The spare tyre also has the optional lockable storage box ($490) attached to it, so you can throw a bit of gear inside there and keep it secure during your travels.

This ute is available in three different spec levels: the base-spec Quartermaster, the Fieldmaster and, this, the Trialmaster.

It’s available with one of two BMW-sourced engines: a 3.0-litre inline-six turbo-petrol engine (producing 210kW at 4750rpm and 450Nm at 1750-4000rpm) or a 3.0-litre six-cylinder turbo-diesel engine – producing 183kW at 3250-4200rpm and 550Nm at 1250rpm-3000rpm.

I tested the diesel-powered variant.

The Trialmaster has a starting price of $118,000 before on-road costs, but our test vehicle has $15,386 worth of accessories onboard pushing its as-tested price up to $133,386.

Standard features onboard the Trialmaster include a 12.3-inch touchscreen multimedia system (with wireless Apple CarPlay and Android Auto), permanent four-wheel drive, centre diff lock, and front and rear skid plates.

Other noteworthy features inside this test vehicle include leather trim (black, $3405), heated front seats ($715), Nappa Leather Driver’s Pack, as well as auxiliary battery, auxiliary charge points, high load auxiliary switch panel and electrical preparation, 400W Inverter, and load bay utility rails.

Other features on the outside of this Trialmaster include a contrast roof – Inky Black ($2460), front and rear diff locks (standard on the Trialmaster), raised air intake, privacy glass ($770), safari windows ($2720), 17.0-inch alloy wheels ($1165), Class III 1-7/8” NAS tow hitch and electrics, a load bay liner, and a spare wheel lockable storage box ($490).

Exterior paint colours include the standard Britannia Blue (solid) or you can choose from Scottish White (solid, $1155), Magic Mushroom (solid, $1155), Eldoret Blue (solid, $1155), Sela Green (solid, $1155), Inky Black (solid, $1155), Devil Red (solid, $1315), Shale Blue (metallic, $1520), Queen's Red (metallic, $1520), Donny Grey (metallic, $1520), or Sterling Silver (metallic, $1520).

But what you want to know is how is it off-road and is it a replacement for the 70 Series, so let’s keep punching on through this yarn.

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.

The Ineos Grenadier Quartermaster is available with either a 3.0-litre inline-six turbo-petrol engine (producing 210kW at 4750rpm and 450Nm at 1750-4000rpm) or a 3.0-litre six-cylinder turbo-diesel engine – producing 183kW at 3250-4200rpm and 550Nm at 1250rpm-3000rpm.

Both engines are from BMW. Our test vehicle has the diesel.

This Quartermaster has an eight-speed ZF automatic transmission and a dual transfer case (high- and low-range 4WD), as well as a front, centre and rear diff lock.

This is a nicely refined engine-and-auto combination, offering up a decent punch of power and torque across a broad rev range when it’s needed.

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.

Official fuel consumption is 10.5L/100km on a combined cycle.

On this test, I recorded 12.3L/100km.

The Quartermaster has a 90-litre fuel tank so, going by that fuel figure, you could reasonably expect a driving range of about 730km from a full tank. However, long-range fuel tanks are available, so there’s always that option.

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.

First things first, just to put your mind at ease – the Quartermaster is not absolutely terrible to drive on road, in fact it’s actually quite nice: planted, comfortable (on coil-spring suspension), and refined (for a ute).

It’s no surprise that a long four-wheel-drive ute does really well on-road, even if it is a heavy solid axle vehicle and not particularly dynamic.

What's also not surprising – because on paper this is an off-road beast – is that the Quartermaster is very capable off-road.

It has three diff locks (front, centre and rear), off-road mode, hill descent control and more, so it's an effective mix of traditional mechanicals and driver-assist tech. That's the dual range transfer case, but it also has electronic traction control. The 3.0-litre turbo-diesel engine and the eight-speed automatic transmission work well in on-road situations and it's also a clever smooth combination in off-road scenarios.

So there's plenty to like about this ute when it comes to 4WDing.

Be aware though: this is a big, heavy vehicle with a long wheelbase, so it takes considered driving to steer around – it has a big turning circle at 14.5 metres – but that's not to say those dimensions and those characteristics ruin it off-road because they don't. The Quartermaster simply requires a bit more thought when you're driving it.

If you haven't spent a lot of time or any time in vehicles like this, such as the Toyota LandCruiser 70 series or of that sort of ilk – big long old-school four wheel drive utes – then you may have a bit of an issue with the steering. It is slow, and there is a lot of play to it, especially off-centre. It does feel floaty and it takes a lot of effort and constant micro-corrections when you're driving to keep it on track and to keep it going where you want to. Put it this way: it’s not self-centred so you have to work at getting it back on track once you’ve taken on a turn.

But I like that, because four-wheel driving should be an entirely immersive experience, you should be always directly involved in the process and in this ute you are.

There’s plenty of power and torque across a nice rev range, with plenty of torque down low, which is crucial when off-roading.

And while the stretched wheelbase makes the underbody vulnerable to knocks and scrapes, especially over more severe 4WD-only terrain, the Quartermaster actually manages quite well.

Its approach, ramp breakover and departure angles – 36.2, 26.2 and 22.6 – are reasonable for something of this size and with 264mm of ground clearance and 800mm of wading depth, this ute has the measurements to cope with most off-road challenges you could throw dirt at.

Another thing I like about the Quartermaster is the fact it retains an old stubby stick, that’s working off the dual-range transfer case, to put the vehicle into low range and that's a welcome touch and a practical nod to the past, rather than a button or a dial.

As mentioned earlier, it has live axles, so there’s flex through the front and rear, although it'd be even better with a swaybar disconnect system onboard (as in the Jeep Gladiator).

This Trialmaster gets the BFG KO2s and where the standard tyres on a contemporary ute may not be up to scratch in off-roading terms, the KO2s work really well. It’s impressive what a difference decent all-terrains make, and if you want to get into the sloppy stuff, then you might consider getting some mud-terrain tyres.

So the Quartermaster is a very capable four-wheel-drive ute and there's a lot to like about it, but the issue with a vehicle like this is that people may come into it not understanding exactly how it rides, how it drives and how involved you actually have to be and the fact that there are lots of compromises, indeed some sacrifices.

You're not getting as much driver-assist technology as you get in other utes, and it doesn't drive as precisely or perhaps as comfortably as some other utes – but that's missing the point.

The Quartermaster is about that all-encompassing off-roading experience. And if you get in one of these things, you have to be all-in, ready for the bumps and the discomfort and the effort it requires but all of those things add to the appeal of this ute, rather than detract from it.

And that's a major point of difference with this ute over others in the market: in being faithful to the spirit of old-school 4WDing, Ineos has been willing to forgo those things which people have come to expect and as a result it may only draw the faithful, the committed, who are all-in for off-road adventure.

Where the Quartermaster falls short, however, is in terms of practical use because its payload is 832kg in the diesel version and that’s disappointing, especially when a 2.8-litre LC70 GXL dual-cab can cope with 1325kg.

It is rated to tow 750kg unbraked, and 3500kg braked and with a kerb weight of 2718kg it has a GVM of 3550kg and a GCM of 7000kg.

The Ineos Grenadier Quartermaster does not have an ANCAP safety rating because it has not been tested.

As standard, it has six airbags, electronic stability and traction control, rear park assist, a tyre-pressure monitoring system, and trailer-stability assist.

It does not have auto emergency braking (AEB), adaptive cruise control, blind-spot monitoring, lane-keep assist, or traffic sign recognition.

The Quartermaster does have a rear-view camera, but the screen is quite small.

Front and rear parking sensors are standard on the Fieldmaster and Trialmaster, but optional on the base-spec Quartermaster.

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.

The Ineos Grenadier Quartermaster is covered by a five-year/unlimited km warranty, not the best in terms of years of coverage, but on par with the likes of the LC70.

A 12-year anti-perforation warranty – covering body sheet metal panels and chassis frame against inside-to-outside corrosion caused by defective materials or workmanship – applies to this ute.

No capped-price servicing is available and service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest, and total cost for the five years is $4626 for the diesel and $4896 for the petrol.

At the time of writing, Ineos has 25 sales and service centres, two sales-only centres and 55 service-only centres spread throughout Australia with a focus on regional and rural areas.
