BMW X Models vs Mercedes-Benz G63

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.

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

The 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.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

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).

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

Okay, you're laying down a quarter of a million bucks ($247,329 before on-road costs) and it's fair to expect some serious tech and standard equipment to keep you feeling warm and fuzzy after you're finished impressing friends and family with the G 63's howling acceleration.

For a start, there's a bunch of leading-edge safety tech on-board (detailed in the safety section below), and as expected that substantial cost-of-entry brings an extensive list of luxury features.

We've touched on the twin 12.3-inch 'Widescreen Cockpit', and available media includes digital radio and TV tuner, internet connectivity and 3D nav (with dynamic route guidance), as well as smartphone integration with Apple CarPlay and Android Auto.

Audio is a thumping 15-speaker, and 590-watt Burmester surround sound system, and the ambient lighting set-up offers a choice of 64 colours.

Also included are 'Multibeam' LED headlights, 'AMG Ride Control' adaptive damping, a 'Parking Package' with 'Active Parking Assist' and 360 camera, a sliding glass sunroof (with tilt function), the selectable AMG sports exhaust system, keyless entry and start, the AMG Performance steering wheel (trimmed in nappa leather), and 21-inch AMG '5-Twin spoke' alloy wheels.

Then there are the three 100 per cent differential locks (plus an 'off-road information centre'), electronically adjustable front seats (ventilated front and heated front and outer rear), steering column and mirrors (with memory function), three-zone climate control, nappa leather upholstery, a leather-finished dashboard with open-pore ash wood trim, a 'Dinamica' microfibre roof liner, and an AMG-specific IWC design analogue clock. Plus, the 'Dynamic Select' system enables a choice of pre-set driving profiles or individual settings.

The optional 'Exclusive Interior Plus Package' ($10,300) fitted to 'our' car adds deluxe nappa hide on the dashboard, door centre panels and grab handle, as well as a diamond quilted treatment on the seat centres, a black 'Dinamica' roof liner, velour floor mats (with edging in nappa leather), a frameless interior mirror and air vents in 'Silvershadow'.

On top of that the test vehicle was optioned with the 'Night Package' ($5900) detailed in the Design section, and Designo 'diamond white bright' paint ($5900) for a manufacturer's recommended list price (MRLP) of $269,429.

That puts the G 63 in the same price and equipment ballpark as the supercharged V8 Range Rover Autobiography ($268,900), twin-turbo V8 Porsche Cayenne Turbo ($239,400), and its Mercedes-AMG GLS 63 sibling ($221,729), powered by a version of the 5.5-litre twin-turbo V8 used in the first-gen G 63.

An impressive trio of alternatives, but in reality the idiosyncratic G 63 doesn't have any direct competitors, and for those who give in to the pull of its powerful tractor beams value-for-money becomes a uniquely personal concept.

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 G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

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. 

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

The second-gen G 63 hasn't been assessed by ANCAP or Euro NCAP but its new electronic architecture brings the car up to speed on active safety tech, now incorporating 'Distronic' cruise control with 'Active Distance Assist', 'Active Brake Assist', AEB (forward and reverse), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Adaptive High-Beam Assist', tyre pressure monitoring, and 'Traffic Sign Assist'. Plus, the 'Pre-Safe' system prepares the vehicle and occupants in the face of an inevitable collision.

And once that impact has occurred, you're protected by nine airbags, including rear seat airbags, full-length curtains and a driver's knee bag.

There are three top tether points for child restraints/seats across the back seat, with ISOFIX anchors in the two outer positions.

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.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.
