Mercedes-Benz GLE-Class vs Ram 1500

What's the difference?

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.

New engine or not, the facelifted Ram 1500 continues the theme of big US pick-ups by being capable of extreme towing feats as well as offering interior and cargo space that the mid-sized dual-cabs can only dream of.

That said, if you don’t need to tow 4.5 tonnes or seat five large adults, then maybe the 1500 and its ilk are overkill. Certainly, that’s the mood among many consumers who simply find them too much of a good thing.

Our pick would probably be the Laramie Sport for its superior ride quality, more sensible 20-inch tyres and reduced price. It can also tow a little more than the Limited, if that’s important to you.

On paper, of course, the Limited with its stonking engine tune should get our vote, but there’s absolutely no way the less powerful Laramie is anything but a powerhouse in its own right. But either version manages to carry off the feeling of being a high-end product, with refinement levels lacking in a lot of diesel-powered alternatives.

Yet, there are still compromises: The Ram is unlikely to be especially compatible with the average Aussie bush track (in width terms, anyway, on tracks formed by Toyota LandCrusiers and Nissan Patrols). And even though efficiency is up with the new engine, this will still not be a cheap vehicle to run day to day. Nor is the purchase price any less scary than its competitors’.

And of course, as with any of these full-sized trucks, buying them for the right reasons rather than a fashion statement is crucial to their viability once the new-car shine has worn off and car spaces begin to look smaller and driveways narrower than they ever have.

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.

There’s not much point releasing a new model if your neighbours can’t pick the difference. So, Ram has revised the front and rear fascias of the pick-up with new grilles and a specific bonnet for the Limited. There are also new head and tail-light assemblies, a new front bumper and alloy wheel designs.

The Limited is a little sportier looking thanks to blacked-out door handles, grille, mirror covers, and the headlights that include an animated welcome when the vehicle is unlocked.

Ram calls this black-out stuff the Night Edition and it’s been made standard on all Australian Limiteds. The flagship version also gets a more sculpted bonnet for a more aggressive look. Strangely enough, though, all those black-outs somehow make the base grade look a little more high end to some eyes.

The rest of the deal remains the usual biscuits and gravy of big pick-ups, including the two-plus metre width and the requirement to often find two adjacent parking spaces before the grocery shopping can commence. What did you expect?

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.

Inside, the 2025 Ram 1500 is also updated with a larger 14.4-inch infotainment touchscreen with wireless Apple CarPlay and wired Android Auto, supplemented by a 10.5-inch passenger screen and dual wireless smartphone chargers.

The passenger’s screen is a big deal, too, as it allows the passenger to upload navigation way-points and destinations, watch a movie, or search the internet via a connected phone. And the driver sees none of it thanks to the blackout screen tech.

Even though Ram has obviously gone to a lot of trouble to make the right-hand-drive conversion seamless and perfect, we still wonder why the indicator stalk wasn’t moved to the right of the column. Cost, probably, and the placement of the rotary dial for gear selection is less than perfect, too. What we’d really like to see would be a column-mounted gear-shift, as well as paddle shifters which are brilliant when towing big loads.

The front-seat area is home to no less than three USB-A and three USB-C charging ports, while there are also two of each in the rear seat.

There’s a storage area under the rear seat which also flips up to form a large load area. There’s even a secret cubby-hole under the carpet in the rear capable of storing a laptop or small bag.

In place, the rear seat is another of the Ram’s big selling points compared with conventional dual-cab utes. The foot and leg room is strides ahead of the mid-sized pack and the seat itself is also a better class of perch. The dual-pane panoramic sunroof keeps it all light and airy, too. Plenty of grab handles and those automatic side-steps make getting in and out a pretty civilised process.

Despite the change in engine, the six-cylinder pick-up retains its 4500kg maximum braked towing capacity – at least in Laramie Sport form. That, however, is contingent on the use of a 70mm tow-ball, while towing drops back to 3500kg with the standard 50mm ball. All Aussie Rams have a tow-bar as standard.

The Ram 1500 Limited drops 300kg in its maximum braked towing capacity rating to 4200kg. That, says Ram, is purely because the Limited is a high-performance vehicle first and a load-lugger second, although one suspects the 22-inch Pirelli Scorpion tyres might be a factor in that as well.

As for payload, the 2025 Ram 1500 Laramie Sport features an 863kg capacity, while the Limited comes in at 782.5kg – 20kg and 17.5kg more than the pre-facelift version.

The tub features a spray-on liner and a cargo divider. There’s also a standard tri-fold tonneau cover for Australian 1500s, not to mention a fold-out step for accessing objects at the bottom of the tray. Powered side-steps are also standard on our Rams, backing up the prestige price-tag.

A powered tailgate is another nice inclusion which can be raised and lowered by touch or via the key-fob.

Fortunately, the twin storage bins along the top of each side of the tub remain, complete with their drain holes just perfect for adding ice and cool drinks.

The first thing to know is that the cut-price, $120,000, Bighorn variant of the Ram 1500 has not made it to the other side of the transition to the facelifted Aussie range. Instead, the range now kicks off with the Laramie Sport which, at $141,950, before on-road costs is exactly the same price as the outgoing Hemi-powered version.

The only other grade in the current line-up is the flagship Limited which now carries a sticker of $159,950, which is $3000 up on the previous Limited. If you can wait until very late this year (according to Ram) there should be a Bighorn replacement available to bring the price of 1500 admission down considerably.

However, it’s worth remembering that the previous Bighorn model missed out on some important safety kit, so until we’ve seen the specifications, we’ll reserve judgment.

There’s no getting around the landed cost of these vehicles (thanks to the typically dreadful exchange rate plus the cost of converting them locally to right-hand drive) puts them at the premium end of the price scale. So, to fit with that, Ram has made a lot of gear standard on Australian examples - gear that is not standard in the US, for instance.

That includes things like the panoramic twin-sunroof, the Night Edition graphics on the Limited, but across the board, these are highly specified vehicles.

For instance, the entry-level Laramie Sport (which uses the standard output version of the new engine) gets all the driving modes and all-wheel-drive functionality, LED lighting, the 14.2 inch, portrait-oriented central screen, Harman Kardon stereo, 20-inch alloy wheels, dual wireless phone charging, wireless connectivity, powered tailgate, reversing camera and parking sensors.

Leather trim is standard and so is the overall interior look that suggests high-end finishes and fittings. Heated and ventilated seats in all five positions are also standard.

Move up to the Limited and things get even swisher. The front seats now have a five-way massage function, there’s extra safety in the form of traffic sign recognition, the headlights feature an animation function, there’s proximity lighting, a switchable digital rear-view mirror, surround cameras and 22-inch alloy wheels. Crucially, there are also mechanical upgrades including the high-output version of the Hurricane engine and air suspension. The fuel tank also grows from the Laramie’s 98-litre unit to a full 125 litres.

What’s missing? At this price-point, an electrically adjustable steering column and a head-up display for the driver, not to mention a network of smart towing cameras and electronic towing-assistance programs that at least one of the Ram 1500’s major competitors boasts as standard.

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.

Here’s where the Ram world gets flipped on its head.

The new inline six-cylinder engine for the 1500 measures 3.0 litres which sounds like a relatively small unit for a vehicle this size. But don’t be fooled, because with twin turbochargers it really comes out swinging.

There are two states of tune for the engine dubbed Hurricane, starting with the basic tune that develops 313kW and 635Nm of torque. That’s a good chunk more than the old V8, in fact, 22kW and 79Nm more.

But it gets better. If you pony up for the higher-spec 1500 Limited you’ll find the engine bay now contains what Ram calls the 'high-output' version of the Hurricane. In that form, it cranks out an impressive 403kW and 707Nm. In old-school horsepower terms, those 403kW equal 540 ponies.

The extra power and torque comes from more turbo boost and, to cope with that, the High Output version of the engine sports a little less compression but twice the number of fuel pumps (two) to deliver the fuel.

Both versions of the inline six also use an intercooler with its own cooling system, rather than relying on the engine’s coolant reservoir.

In each case, the turbocharged engine sends its outputs through an eight-speed conventional automatic transmission.

The Ram also features four-wheel drive with a two-speed transfer-case for low-ratio off-road gearing. As well as two-wheel drive and a low-range four-wheel-drive setting, there’s also 4WD auto mode that allows the Ram to be driven on bitumen in all-wheel drive which is a huge bonus when towing in wet conditions.

The updated pick-up also offers five drive models, selectable via the steering wheel buttons. They include Normal, Sport, Towing, Off-Road and Snow.

Mechanically, the main difference between the two grades (engine output aside) is underneath where the Limited gets air suspension rather than the Laramie Sport’s conventional steel coil springs.

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.

Because of the classification the Ram 1500 falls into, there’s no compulsion for the manufacturer to state an official fuel consumption figure in Australia. And in this case, Ram doesn’t.

The most definitive statement we could get was that the 313kW tune is 12 per cent more fuel efficient than the outgoing Hemi V8, and the high-output engine is closer to 3.4 per cent more efficient. Although whether that extrapolates directly to a 12 and 3.4 per cent fuel saving respectively is not clear.

Our test drive included a stretch of gentle highway cruising, during which we saw an average of about 8.5 litres per 100km, which is about the best you can hope for, but remains a decent figure for such a machine.

In normal use, you can expect that to creep up, and seat of the pants says the standard-output engine should be good for a high 10 litres per 100km, and the high-output unit closer to a high-11.

Obviously, that will go to hell during off-road work or when towing any sort of trailer.

With the Laramie’s 98-litre fuel tank, that model should see an easy 700 to 800km between fills, while the Limited’s larger, 125-litre tank, should take it closer to a realistic 1000km range.

Bear in mind, though, that while the Laramie is happy with standard ULP, the higher compression and extra turbo boost of the Limited means it requires the more expensive Premium brew, which might be harder to find in the outback.

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.

If speed and acceleration were your only metrics, then the new Hurricane six-cylinder engine really delivers. Against a zero to 100km/h time of about 7.5 seconds for the outgoing Hemi V8, the standard-output Laramie Sport takes around 6.2 seconds for the same journey.

Point the high-output version down the same piece of hotmix, and the time to 100km/h falls even further to about 5.5 seconds and maybe even less if you get the perfect launch. Oh, and those figures were recorded with the transmission in 4-Auto, as trying the same thing in two-wheel drive will see the rear tyres turn into smoke bombs.

So, yes, it’s very fast for such a big truck. In fact, it’s fast by any standards, really. But does it feel 'right’ for a pick-up?

While it’s obviously not a V8, there is a huge sense of swelling, cresting performance on tap as well as a feeling that the turbo boost is available pretty much immediately. There’s very little lag, in fact, and, in the traditional manner of inline sixes, the Hurricane feels smooth and sweet all the way across the face of the tachometer.

What you can also feel is the eight-speed transmission really making its presence felt. Obviously, getting this much mass moving requires full use of all those ratios and even though the shifts themselves are crisp and silky, there is more evidence of the transmission at work than in a lighter vehicle with the same sort of torque. File this under `observations’ rather than `complaints’.

The steering is light but accurate and helps create the impression that the Ram is not as big to drive as it is to look at. That’s helped by the ride quality which, frankly, is superior in the base grade with its conventional steel springs. The Limited on its air springs feels a bit more lively and jiggly over patchy surfaces, but part of this is also surely the difference between the Laramie’s 20-inch tyres and the 22-inch Pirellis fitted to the Limited.

There’s a degree of tyre roar on coarse surfaces but, overall, if all you know about American picks-ups is hitching a ride in a 1976 F-100, you’re going to be very impressed at how these things have matured and become refined to the point where they’re a genuine high-end experience in many ways.

As well as all the driver aids seen when this model was originally launched a few years ago, the facelift has brought some important safety upgrades. Those start with a steering assistance system that works in conjunction with the new forward collision warning program.

There’s now also intersection-assist and a driver drowsiness monitor. The Limited adds to that with traffic sign recognition and a surround camera system.

Existing driver aids across the range include autonomous emergency braking (AEB), blind-spot monitoring, lane-keeping assistance and six airbags including curtain airbags.

A tyre pressure monitoring system is also a great safety feature in a vehicle like this that might be frequently hitched up to heavy loads. Throw in a reversing camera and front and rear parking sensors and it starts to look okay.

But the one thing that is missing is the equivalent towing assistant package that is so popular on the Ford F-150. With a range of cameras and electronics to guide the hitching-up process and then monitoring the load en route, the Ford’s system should be standard on all these big tow-rigs.

The Ram also has adaptive cruise control but, for those who don’t like these active cruise systems, a standard cruise control setting is available at the flick of a switch.

Three ISOFIX child restrain mounting points are fitted to the rear seat.

The Ram hasn’t been crash tested and, since there’s no compulsion to do so in this class of vehicle, don’t expect one to be hurled into the crash-lab wall any time soon.

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.

Ram probably needs to do a bit of catching up in this department, as the 1500 seems off the pace warranty wise.

The three-year/100,000km factory warranty might be okay in throw-away North America, but it doesn’t really send the right message here. For reference, the Chevrolet Silverado range also has three-year warranty, while both the Ford F-150 and Toyota Tundra run to five years of cover.

Service intervals are every 12 months or 12,000km, and Ram has no capped-price servicing for the pick-up, although previous experiences tells us that the Hemi version was quite reasonably priced to service. Let’s hope that continues with the turbocharged version.
