Ford F-350 vs Mercedes-Benz GLE-Class

What's the difference?

If you’ve got something really heavy to tow and you have the budget to do it in grand style and with minimal effort, then a Super Duty could be just what you’re looking for. Its gargantuan proportions make it impractical for daily driving in Australian city and suburban traffic, but as a heavy-duty tow vehicle, particularly for long-haul open highway work, you’ll feel like king of the road.

Vehicle supplied by Harrison F-Trucks.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

Needless to say, the MY18 F350 Super Duty 4x4 is a monster, even in this SWB specification. The massive 4059mm wheelbase is 839mm longer than a Ranger Wildtrak, which is also dwarfed by the Super Duty’s 6350mm overall length (961mm longer). The F-Series’ 2032mm width is 182mm wider than the Ranger, and its 2065mm height is 217mm taller. It's like a Ranger that's been fed heaps of fertiliser.

Underneath is the kind of heavy-metal hardware needed to justify a Super Duty badge. Ford claims its massive fully-boxed steel ladder-frame chassis is up to 24 times stiffer than the previous generation, along with improved corrosion resistance. The cargo tub is made from military-grade aluminium with the dual benefits of less weight and no rust. A tough spray-on cargo tub liner boosts dent and weather protection.

Live axles are used at both ends, suspended on huge leaf spring packs at the rear and softer-riding coils up front. Steering and four-wheel disc braking are both power-assisted, of course, and there’s a choice of trailer-towing hitches available.

As you would expect, cabin space for both front and rear occupants is palatial, with even tall adults feeling dwarfed by its enormous dimensions. Rear passenger leg and shoulder room even for tall adults is limousine-grade, although headroom is reduced (but still adequate) due to the lower roof lining surrounding the full-length sunroof.

The overall fit and finish of the dashboard, following Harrison’s local RHD conversion process, displays quality workmanship. However, some DNA from its Kentucky birthplace remains in the control screen’s software, which, for example, displays 911 Assist instead of 000, and a left-side driver’s seat icon for the massage control. We also noticed that the AM radio station display only moves in 10kHz increments without the ability to tune between them (too bad if you like talkback).

There’s also no driver’s left footrest and the parking brake pedal seems overly high, requiring the raising of your left knee above steering-wheel height to get your boot on it.

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.

Our F-350 test vehicle with its F-250 downgrade results in a 700kg decrease in both payload and tow ratings. In other words, based on Harrison’s figures, in full F-350 specification it has a 1700kg payload capacity and 9700kg GCM, which means it can legally tow up to 4510kg of braked trailer with a full payload or up to 6210kg without. In our F-250 form it offers a 1000kg payload with 9000kg GCM, and can legally tow up to 3810kg of braked trailer with a full payload, or 4810kg without.

The huge cargo tub has a load floor length of 2080mm and width of 1700mm, with 1283mm between the wheel arches allowing ample room for a standard 1160mm-square Aussie pallet. There’s a total of eight tie-down points, overhead and internal lighting plus key fob operation of the tailgate, which houses a handy fold-out step and grab handle for easy cargo tub access.

The sumptuous cabin has plenty of storage options, including a single glovebox, and a bottle holder and two storage bins in each front door. The centre console has an open storage cubby at the front, another open storage bin and two bottle holders in the centre, a cavernous box behind that with a padded lid which doubles as a comfortable armrest, and two more bottle/cup holders at the back.

Those in the rear seat also get a fold-down centre armrest with two pop-out cup holders and each rear door has a bottle holder and two storage bins. There are also flexible storage pockets on the rear of both front seats and the 60/40-split rear seat base cushions swing up through 90 degrees and lock into position, revealing a huge full-width storage area underneath.

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).

The F350 Super Duty is powered by Ford’s common rail 6.7-litre Power Stroke V8 turbo diesel, which, with four valves per cylinder and variable vane turbocharger, punches out 335kW at 2800rpm and a massive 1267Nm of torque at only 1800rpm.

The SelectShift six-speed automatic transmission is also designed and built by Ford. Its triple-plate, two-stage torque converter offers full lock-up capability as low as 900rpm, and there’s a dedicated tow/haul mode which avoids unwanted shifts on climbs and provides powerful engine braking on descents.

The exhaust brake can also be manually selected. The 4x4 system is part-time dual-range, with auto-locking front hubs and shift-on-the-fly engagement.

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.

Flick through a Super Duty sales brochure and you won’t find any reference to fuel economy ratings. However, for what it’s worth we crunched some figures at the end of our relatively short 200km test based on trip meter and fuel bowser readings, resulting in a reasonable 15.8L/100km.

That’s not far away from the dash read-out at 14.2, so with its big 130-litre fuel tank you could expect a driving range of around 820km.

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.

You sit up nice and high in very comfortable seats, with a commanding view of surrounding traffic and the road ahead. We quickly adapted to the width and height of the Super Duty, but the major issue in city and suburban driving was its oil-tanker length, which required later turn-in on tight corners to provide kerbside clearance. We also needed to check that there was ample reversing room when choosing a space in a parking lot, to ensure we didn’t get wedged when trying to leave.

With the big turbo diesel V8’s 1267Nm of torque being tapped at only 1800rpm, it provides spirited getaways from traffic lights, and easily keeps up with normal city and suburban traffic flow with your big toe barely touching the accelerator pedal.

The ride quality without a load is quite good on smooth surfaces, with its massive 3.5 tonne kerb weight feeling like the tyres are leaving indents in the bitumen. However, over rougher roads and larger obstacles like speeds humps, it starts to bounce around more and can feel quite ponderous at times. However, this is to be expected in an empty vehicle with such high payload and tow ratings.

The steering is surprisingly direct and firm in feel. It’s also quite linear in turning weight regardless of road speed, without the more noticeable changes evident in its little brother Ranger, which is very light at parking speeds but gets noticeably firmer as speeds increase.

Braking is reasonably responsive but like other giant US pick-ups we’ve tested, you have to get them quite hot to make them really bite. That’s because their pad compounds tend to be on the hard side, given they have to cope with the high temperatures generated by heavy-duty towing.

The engine exhaust brake is surprisingly quiet and very effective at slowing the vehicle, aided by more aggressive downshifts in the six-speed auto.

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.

Harrison F Trucks provides a four-year/130,000km warranty, which it claims is the same as the Ford warranty with standard exclusions. Harrison also provides four-year premium roadside assistance.

Scheduled servicing is 12 months/10,000km with costs ranging between $495 and $1400.

Harrison says servicing can be done at any certified service department in Australia, with direct communication with Harrison’s service manager if required for diagnostics and advice.

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.
