BMW X Models vs Mercedes-Benz GLE-Class

What's the difference?

There is little doubt the new X2 represents a vast improvement over the original model. The design alone gives it a lot more presence. 

More interior and boot space also helps widen the SUV’s appeal and the significant tech updates are welcome.

It is on the pricey side and there are a few too many options that should be standard. 

However, the M35i is hard to ignore as a sporty premium crossover, and the iX2 xDrive30 is the sort of electric SUV that should worry Volvo.

They both have their own distinct flavours, so there’s no dud in this line-up. Of course, we will hold final thoughts for the local launch when we can drive all four grades. But until then, it’s a welcome return to form for the X2.

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.

The second-gen X2 looks very different to the original from 2018. That first X2 had a squat stance, looked more like a hatchback than an SUV, and the glasshouse appeared as though it had been squished into the body of the car.

The 2024 X2 adopts a similar design philosophy to the X4 and X6 - swoopy, coupe-like roofline and liftback, and bold styling elements at the front and rear.

It has a much more upright, flush front end, freshly designed large kidney grille and an edgy headlight design. There’s flared wheel arches and broad shoulders at the rear, as well as a cool new horizontal tail-light signature.

The X2 has grown in size in a big way. It’s 194mm longer, 21mm wider, and 64mm taller than the outgoing model. That naturally means more space inside, too.

Inside there are big changes. The X2 adopts elements introduced by the excellent iX SUV a couple of years ago. They include the curved display, and a floating arm rest with a control panel. Some of this is also familiar from the X1.

The materials mostly look and feel like they are high quality, and there is an appealing minimalism to the overall design and layout. The chunky sports steering wheel is visually appealing, but it’s a bit too thick in my hand.

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.

Where the previous X2 was a very small crossover with niche appeal, the increase in size for the new model means more people will be interested in it. Possibly even people with a small family.

Those increased dimensions pay dividends inside, with ample headroom up front and more than enough space across the front row, although the raised armrest console is somewhat narrow. 

The seats in both the iX2 xDrive30 and the M35i xDrive are very supportive thanks to ample bolstering, but both were also on the firm side. The iX2’s synthetic leather was slightly more comfortable than the M35i’s sports-focused front seats.

The power-adjustable seats and height- and reach-adjustable steering wheel means it’s not hard to find a decent driving position, but forward vision is impeded by a very thick A-pillar, and the letterbox-like rear windscreen in the X2 means rearward vision is limited. Good thing it has excellent parking cameras and sensors. 

Storage is decent in the X2, with room for big bottles in the door cavity, and a few nooks and large open spaces in the console. Although secure storage is limited with the armrest housing a very shallow space. I do like BMW’s phone charger setup. Rather than lying on a pad, it slots into a vertical holder that has a latch to keep it in place when cornering. The only drawback is that you can see the screen which could potentially distract some drivers.

The X2 introduces operating system nine to iDrive, which is housed in the central part of the curved display and operated by touchscreen or the controller on the floating central console. After some familiarisation, the functionality isn’t that much different to the previous version of the operating system. The main menu looks cool and is mostly easy to navigate. The sub-menu icons - of which there are heaps - look a little Microsoft Windows.

The X2 has drive modes that also interact with the interior of the car and change lighting, EV noise and more. They include Personal Mode, Sport Mode and Efficient Mode as standard, but if you opt for (and pay extra for) BMW Digital Premium, the modes extend to Expressive Mode, Relax Mode and Digital Art Mode. Some of these are quite cool, especially some of the EV sounds, but would I use them everyday? Probably not.

The clearest indication of increased space is in the second row. There’s much more legroom than the old X2, and behind my six-foot frame I had enough space with a couple of centimetres between my knees and the front seat backs. Toe room was very limited, however. 

The roof has been scalloped out to ensure more headroom, which is welcome given the extra sloping roofline.

There are a pair of USB-C ports back there, lower air vents, map pockets, decent door storage, and a centre armrest with cup holders.

The boot is sizeable, in both engine grades but you only get a tyre repair kit. There is underfloor storage for the charging cables in the iX2.

At 560 litres with all seats in place and 1470L with the second row stowed, the petrol grades have a bit more space than the iX2 at 525L (all seats in place) and 1400L (second row lowered).

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).

Each of the four grades come with a different powertrain, and the xDrive20i kicks it all off with its 2.0-litre four-cylinder turbocharged petrol unit, making 150kW of power and 300Nm of torque. It drives all four wheels via a seven-speed dual-clutch transmission and can hit 100km/h in 7.4 seconds.

The xDrive M35i ups the fun factor with a gruntier 2.0-litre four-cylinder turbo-petrol unit, driving all four wheels via the same transmission as the 20i, all while delivering power and torque of 233kW/400Nm This ensures a 0-100km/h dash of 5.4 seconds.

The iX2 eDrive20 is powered by a 150kW/247Nm electric motor on its front axle, and the iX2 xDrive 30 uses two motors - one on the front and one on the rear axle for all-wheel-drive traction. The total system output is 230kW and 494Nm and the xDrive30 gets to 100km/h in just 5.6 seconds.

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.

A fuel-use figure for the xDrive20i is yet to be confirmed, but the front-wheel-drive sDrive20i offered in Europe with a three-cylinder engine sips as little as six litres per 100 kilometres on the combined cycle. Expect the Australian version to be a little higher than that given it’s AWD and has a more potent engine.

The M35i consumes 7.7L/100km. 

The high-voltage 64.8kWh lithium-ion battery in the iX2 ensures a driving range on the WLTP cycle of between up to 477 kilometres in the eDrive20 and between 417 and 449km for the xDrive30. 

The latter has an energy efficiency range of 16.3 to 17.7kWh/100km, and BMW says you should be able to top up the battery from 10 to 80 per cent in 29 minutes at a fast charging station.

That driving range is not bad compared with the Lexus UX300e and Peugeot e-2008, but not quite as impressive as the Volvo C40 twin-motor. 

I missed out on checking the energy efficiency figure of the iX2 xDrive30 following our drive, but after an 88km drive loop, the iX2’s range had dropped by 91km, which is just a 3km difference.

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 M135i xDriveis undeniably quick off the mark. The lovely 2.0L turbo engine is well matched to the seven-speed dual-clutch and it’s responsive and willing from a standing start and when overtaking.

The engine sounds lovely too, although we suspect it’s amplified in the cabin, and steering is as sharp as it should be in a warmed-up performance SUV. We darted through some very twisty roads outside Lisbon and had quite a lot of fun in the process, so the M Performance badge is justified. 

I drove the previous-generation X2 M35i a few years back and was disappointed with the ride quality. It was quite jiggly on uneven road surfaces and way too firm.

While the new version still has a firm tune to aid dynamic driving, it is much more compliant than the old car and overall ride comfort has improved.

The iX2 is also quick off the mark and in xDrive30 guise is only 0.2sec slower to 100km/h than the M35i. 

That lively, smooth EV acceleration is present here, adding a sense of fun to the iX2.

It too has sharp steering, and the cabin is hushed. Not just because it’s an EV either. We were on coastal roads on a windy day and there was only a hint of wind noise in the cabin.

In some instances taking corners that had typical European walls or houses right up against the road, the iX2 would slow before I had a chance to tap the brakes. But it was hard to tell if that was a vehicle safety function, or the regenerative braking.

The ride in the iX2 was a bit of a mixed bag. It coped with some of the pockmarked roads exceptionally well, soaking up the imperfections. But then on other roads it was a little choppy.

It also bounces a little when you go over speed bumps, but that’s not exclusively an iX2 trait. I’ve felt it on many an EV, given the placement of the very heavy battery packs under the floor.

On the driving tech front, the X2 has a well executed head-up display projected directly onto the windscreen. It includes the speedo of course, nav guidance, a crystal clear display and more info. 

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 X2 range is covered by BMW’s five-year, unlimited kilometre warranty - something the German giant only increased from three years back in 2022. This is now the minimum standard.

The battery warranty for the iX2 is eight years or 160,000 kilometres. 

BMW does not have scheduled servicing terms, instead, servicing is condition-based and the car’s computer will alert the driver when to book in for a service.

A five-year servicing package will cost you $3171 for the petrol X2s, while the iX2 is $2186 for six years.

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.
