Ineos Grenadier vs Mercedes-Benz GLE-Class

What's the difference?

The moral of the story here is not to confuse traditional thinking with flawed thinking. Just because an analogue concept has been around in a fast-moving, electronically-driven industry for a while, doesn’t mean it can’t still be relevant in special circumstances. And as an off-roader, the Grenadier is among the very best of them.

Yes, the Ineos suffers to an extent as a road car because of its off-road bias, but owner familiarity will likely be the key to those compromises fading into the background over time.

Meantime, it’s also true that the original design brief of the Grenadier has been diluted a little as market research and safety realities forced an extra layer of complexity on to some of the major systems.

But even the vehicle’s systems that have remained analogue or old-school have forced their own technology into the frame. The live front axle, for instance, forced the use of recirculating ball steering rather than rack-and-pinion, while Ineos also insisted on the more complex (but arguably more reliable) hydraulic power steering rather over a simpler electric set-up.

Look closely and it’s easy to see how keeping a car rugged and serviceable can become a technically involved process. Simplicity, it seems, can easily breed complexity. It was probably Dolly Parton who put it best when she said, "It costs a lot of money to look this cheap".

There’s little wonder the GLE63 S is back for a second go around, after  clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.

After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.

And for that reason, we’re itching to go for another drive – with or without the family.

This is where the Grenadier makes its statement. It’s resolutely old school with engineering designed to survive the roughest off-road conditions rather than pamper or flatter its occupants.

That starts with the basic construction; a ladder chassis onto which is bolted the body. This is how all off-roaders used to be made and while it has limitations in refinement and weight terms, it’s still an effective way to build something with lots of wheel articulation and strength.

Wheel articulation is also the job of the solid axles front and rear. While having independent suspension is great for ride control and comfort, solid axles allow the maximum wheel travel which is what off-roading is all about. Coil springs, rather than leaf springs, are about the only concession to comfort.

The four-wheel drive system is also traditional with a high and low-range gear set that works permanently in four-wheel drive.

A locking centre differential that works in high and low-range is standard and front and rear diff locks are optional. The Grenadier also complies with the old adage that a proper off-roader has a minimum of two gear-sticks, and not a rotary gear-selector knob in sight.

Even the steering system is aimed at off-road prowess with almost four turns lock-to-lock.

Such a slow ratio suits off-road work where large steering inputs are more likely to get you into trouble than out of it.

And while we now live in a world where power steering is almost always electrically-assisted, the Ineos sticks with hydraulic assistance in the name of reliability and durability and restricting electronics only to where they are essential.

The cabin, too, is distinctly retro with analogue gauges wherever possible and large, tactile switchgear.

But it’s also novel in layout terms with most of the information displayed on the 12.3-inch central info-screen and the area directly in front of the driver kept clear to maximise the view ahead.

The roof-mounted switch panel recalls aircraft practice and, with the Fieldmaster’s glass roof panels in place, the view is reminiscent of sitting in a military helicopter. Mounting electrical gear in the roof also keeps it out of the water during deep river crossings.

Much has been written, meanwhile, about the exterior of the Grenadier. Mainly that it looks like a copy of the old Land Rover Defender. 

But Ineos has previously, er, defended this, claiming that when you design a car purely for functionality, its exterior will usually look something like this.

As it is, the body with its exposed door hinges (although the bolts are fake) short front and rear overhangs and even the utility belt (from which accessories can be slung) are all business.

The rough-and-tough angle even extends to details like the tyres’ valve stems which are metal rather than traditional rubber as a means of making them stronger and less likely to be damaged.

This is a thoroughly considered vehicle.

First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.

Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.

Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.

The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.

Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.

From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.

At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.

It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).

Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.

The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.

That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.

Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

This is, of course, the Grenadier’s reason for existing in the first place. With a mantra of 'Everything you need, nothing you don’t' the Ineos attempts to be as competent, capable and practical as possible within the parameters of a car that has to also be useable, day-to-day comfortable, safe and legal.

Like a lot of high-riding vehicles, getting in and out of the relatively small door openings is not as simple as it might be. Sometimes it seems as though the side-steps are your friend, other times they exist only to smear mud all over your legs.

But once you’re in, the almost vertical windscreen and side glass keep the sun at bay and the front seats seem to be designed for big people which is a nice change.

The tilt and reach-adjustable steering column means everyone can get comfy and even though the back seat feels a bit firm in the cushion, the backrest angle is pretty agreeable.

It’s also nice to see that Ineos has used a proper gearstick with linkages for the high-low range shifter rather than a rotary knob to control an electric motor.

The plethora of tie-down points in the luggage compartment is great but we do wonder about the use of some fairly hard plastics around the cabin, and how they’ll look in a couple of years.

The luggage space is adequate but not hugely generous and while the rear seats do fold down, the location of the battery beneath them means they sit up a bit and don’t form a flat floor.

An accessory drawer system for the load space should fix that, however, raising the floor height to match the folded seats.

Maximum load volume behind the first row in the Utility Wagon is 2088 litres dropping to 2035L in the Station Wagon. Load volume in the wagon with the second row upright is 1152 litres.

There’s lot of evidence of careful thought in the way the Grenadier is laid out and equipped, including a roof that can cope with a rooftop tent or a decent load (hence the ladder) and flat front mudguards that form an impromptu work-bench or, if you add the optional checker-plate sections, a look-out post capable of supporting 150kg.

The 30/70 split tailgate has an optional drop-down work-bench when open but the smaller section is a bit narrow for gaining easy access to your luggage without also opening the larger side.

Other quibbles include the driver’s foot-rest which is huge and placed at a truly bizarre angle, and the small reverse camera screen.

Grouping all the instruments in the centre stack might be good for left- and right-hand drive production, but it means you have to take your eyes off the road to read the digital speedo. A head-up display in front of the driver would be much better.

Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.

That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.

Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.

Better yet, four tie-down points are on hand to help secure loose items,  alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.

In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.

With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.

No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.

There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.

Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.

A  fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.

In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.

The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.

While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.

Priced from $220,600 plus on-road costs, the new GLE63 S wagon is $24,571 dearer than its predecessor. While the rise is unfortunate, it is accompanied by the fitment of a lot more standard equipment.

And the same is true of the new GLE63 S coupe, which is priced from $225,500, making it $22,030 more expensive than its forebear.

Standard equipment for both cars includes metallic paintwork, dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, side steps, soft-close doors, roof rails (wagon only), keyless entry, rear privacy glass and a power-operated tailgate.

Inside you score push-button start, a panoramic sunroof, satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, a head-up display, a power-adjustable steering column, power-adjustable front seats with heating, cooling and massaging functionality, heated front armrests and outboard rear seats, four-zone climate control, stainless-steel pedals and an auto-dimming rearview-mirror feature.

Rivals for the GLE63 S include the less expensive Audi RS Q8 ($208,500) and BMW’s X5 M Competition ($212,900) and X6 M Competition ($218,900).

This is probably the one area where the Ineos can claim to be a product of modern thinking. And that’s because the engine choices – a 3.0-litre inline six-cylinder petrol or diesel – and the eight-speed automatic transmission are all sourced from BMW and ZF, respectively.

Both engines use four-valve-per-cylinder technology and while the petrol boasts 210kW of power and 450Nm of torque.

The diesel isn’t far behind in the power race with 183kW, but trumps the petrol version for torque with 550Nm. Interestingly, the turbo-diesel engine uses all alloy construction, which, while now common in petrol units, is more of a novelty in the diesel world.

The eight-speed transmission feeds into the two-speed transfer-case where it’s sent to each axle via the permanent all-wheel drive system.

Ineos claims either version will get to 100km/h in under 10 seconds and top speed, in deference to the tyres as much as anything, has been limited to 160km/h.

Approach, departure and ramp-over angles are all among the best in the business and Ineos claims a safe wading depth of 800mm. The optional snorkel air-intake is likely to be a very popular addition among Australian buyers.

The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.

As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.

Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.

The official combined cycle fuel economy figures for the petrol and diesel engines respectively are 12.6 litres per 100km and 10.5 litres per 100km.

Realistically, these will be your highway consumption figures and the relatively hefty and aerodynamically blunt Grenadier will never be a fuel sipper. Hitch up a big caravan and use most of the vehicle’s 3500kg towing capacity and that consumption will blow out massively.

As it is, the 90-litre fuel tank should give the petrol model a cruising range of 715km or so, while the diesel should achieve closer to 850km.

It’s worth noting, too, that the diesel version uses AdBlue, so factor that, as well as the currently higher cost of diesel over petrol, into running costs.

The GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.

When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.

And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch  route purely involved high-speed country roads, and you know what that means.

For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.

The first impression when jumping behind the Grenadier’s wheel is that the vehicle is super easy to place accurately at the front.

That’s because the two front corners are easily visible (thanks to the bluff, bull-nose front) and you sit nice and high.

In fact, the Ineos has the knack of immediately feeling smaller than it is, which is a great confidence booster for somebody new to off-roaders.

The steering also helps make a good first impression with no trace of looseness despite the slow ratio and almost four turns lock-to-lock.

The turning circle is also vast, and all of this makes the Grenadier anything but a car to hustle along a twisty road, but the pay-off is when you’re off-road.

In the bush is where this vehicle hits its straps, of course, and take it as read that this thing will go anywhere any other off-roader with number plates will take you.

The live axles give superb wheel articulation (at the expense of a little body roll on the bitumen) and that slow steering makes for accurate wheel placement in low-range going.

The coil springs only add to the wheel articulation, but there’s a small degree of impact harshness on patchy bitumen as a trade-off. We’d happily live with that.

And when you finally do run out of articulation and the Grenadier starts to spins its wheels on loose surfaces and at mind-blowing angles, you simply grab the lever for the centre differential lock and continue on.

And if that’s not enough (provided you’ve optioned them) the front and rear locking diffs turn the vehicle into the next best thing to a bulldozer.

The Ineos is also the car that proves petrol and diesel technologies are getting closer and closer to each other.

The diesel is smooth, refined and quiet, while the petrol’s twin-scroll turbocharger means it grunts like a diesel used to. Our choice would, then, probably be the diesel if only for its greater fuel economy and range.

The eight-speed transmission does a great job on- and off-road and is calibrated separately for the latter with the ability to second guess what’s going on and hold gears where necessary.

We’d still like to see paddle-shifters, however, as the standard T-bar shifter doesn’t allow for the sort of instinctive ratio swapping sometimes required off road.

Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.

Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.

While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.

That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in  first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.

This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.

Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.

What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.

It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.

Of course, there’s more to the GLE63 S experience, like the fact that  it somehow rides like a large SUV yet handles like a sports car.

The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.

The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a  too firm in Sport+, with the ride becoming a little too jittery to be bearable.

Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.

In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.

Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.

Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.

Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.

Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.

ANCAP awarded the second-generation GLE range its maximum five-star rating in 2019, meaning the new GLE63 S gets full marks from the independent safety authority.

Advanced driver-assist systems generously extend to autonomous emergency braking with pedestrian and cyclist detection, lane-keep and steering assist (including emergency), adaptive cruise control with stop and go functionality, traffic-sign recognition, driver attention alert, high-beam assist, active blind-spot monitoring and cross-traffic alert, tyre pressure monitoring, hill-descent control, park assist, surround-view cameras and front and rear parking sensors.

Other standard safety equipment includes nine airbags, anti-skid brakes, electronic brake-force distribution and the usual electronic traction and stability control systems.

The Grenadier is covered by a factory five-year/unlimited kilometre warranty. The chassis and body components are also covered by a 12-year anti-corrosion warranty.

Service intervals are every 12 months or six months in the case of a vehicle being used in harsh conditions.

As with all Mercedes-AMG models, the GLE63 S comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.

It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.
