BMW IX1 vs Mercedes-Benz GLS

What's the difference?

BMW is a true EV pioneer, as the 2014 i3 and subsequent models prove. There’s never been one that we didn’t like. The only problem was that all were expensive. And at times, prohibitively so.

Astoundingly, the iX1 breaks that cycle, comparatively speaking, while impressing us with its design, quality, packaging, dynamics and equipment levels.

As it stands, the xDrive30 is one of the most convincing and best-value medium-sized luxury SUV EVs on the market right now.

Who’d have thought it from a BMW?

The GLS63 is an intimidating beast from afar, but it rewards its occupants in almost every way. Yep, there really isn’t a box it doesn’t tick without serious compromise, such is its breadth of capability.

If there was ever a Swiss Army Knife of cars, the GLS63 is definitely a contender for the title, one that makes it very hard to wipe the smile off your face. Just make sure you can fit it in your garage first…

Arguably the prettiest new BMW SUV you can buy today, the well-proportioned iX1 is nearly impossible to spot over its almost-identical ICE (U11) X1 siblings.

Besides the badging, look for some blue trim bits and pieces inside and out, along with additional digital touchpoints inside.

And while both ride on the same all-new platform that’s resulted in a substantially larger body compared to previous X1 generations, the EV version seems a bit more slammed.

Dimensionally, the iX1 mirrors today’s X1 at 4500mm long and 1845mm wide, and still sits on the same 2692mm wheelbase, but is 26mm shorter at 1616mm tall and offers 35mm less ground clearance at 170mm.

Result? These plus a bunch of aero enhancements mean the slipperiest iX1 manages a Cd of just 0.26, according to BMW.

And, inevitably, the extra size equals more space inside.

If the GLS63 was a Marvel superhero, it would undoubtedly be the Hulk. Simply put, it has road presence like few others. In fact, it’s frankly menacing.

Of course, the GLS is already pretty intimidating due to its sheer size and blocky design, but the GLS63’s full-fat AMG treatment takes it to another level.

Naturally, the GLS63 gets an aggressive body kit, with its purposeful bumpers, side skirts and rear spoiler serving as instant reminders of what you’re dealing with, but it’s AMG’s signature Panamericana grille insert that really hammers home the point.

Around the side, the GLS63’s 22-inch alloy wheels with staggered tyres (front: 275/50, rear: 315/45) make their presence known, positioned below the wheelarch extensions.

That said, some fun’s also had at the rear end, where the GLS63’s diffuser element integrates the foreboding sports exhaust system with quad tailpipes very neatly.

The focused Multibeam LED headlights also look the part, while the opposing LED tail-lights tie everything together outside quite nicely.

Inside, the GLS63 stands out from the GLS crowd with its sports steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are covered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

Of note, the doors bins are unfortunately of the hard plastic variety, which is very disappointing in a vehicle that costs this much. You would expect that cow hide would also been applied to them, but alas it isn’t.

The GLS63’s black headliner serves as an obligatory reminder of its sporting intent, and while it makes for a dark cabin, metallic accents are prominent throughout, while the optional trim (our test vehicle had carbon-fibre) mixes things up, alongside the ambient lighting.

And let’s not forget the GLS63 is still loaded with plenty of cutting-edge technology, including a pair of 12.3-inch displays, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes’ class-leading MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up arguably remains the best there is today thanks to its speed and breadth of functionality and input methods.

BMW also says the iX1’s cabin is almost as roomy in some ways as the larger X3.

Large doors allow for easy entry and egress, onto sumptuous front seats that provide exceptional comfort and support even on longer journeys.

Surrounded by an expansive feeling of space, the interior feels light and airy, as well as fresh, inviting and premium looking – something previous-gen X1s were rarely accused of being.

We’re talking on-brand stuff here, beginning with the excellent driving position, ahead of a crisp and attractive dash that’s pleasing to behold. Push-button starting and a small toggle lever operates the transmission.

An ever-so-slightly curved (towards the driver in the best-BMW old-school way) rectangular binnacle houses two digital displays – a 10.25-inch one ahead of the driver offering an array of configurable electronic dials, as well as a 10.7-inch multimedia touchscreen.

BMW pioneered the multimedia controller more than 20 years ago with iDrive, and this descendent of that system reveals all that expertise gained by being intuitive to operate and quick to respond to commands once familiarised. Which shouldn’t take too long.

It’s all very-EV centric, as the industry inexorably moves to total electrification, but there were a couple of voice-command errors in the iX1, revealing that such systems are still far from perfect. BMW does provide audio volume and climate hard buttons, thankfully, so the basics are looked after.

Speaking of which, the iX1 offers decent levels of vision out, superb ventilation and ample storage in the doors, on the dash and between the front seats. And, as we’ve noted previously in BMWs, the upright smartphone charger is a clever idea. Keeps it in position and is handy to glance at.

Out back, backrest comfort and support is A-OK, and even with the optional sunroof, our test iX1 provided sufficient space for taller bodies, while expected items like ventilation grilles, USB ports and cupholders are fitted.

Note that, though the 40/20/40-split backrests recline slightly, they do not slide as per in the ICE X1, as this is a desirable option.

Nor is the cargo capacity as good in the iX1, due to the inevitable space demanded by that rear-axle-mounted electric motor and battery pack. For the record, ranges from 490 litres to 1495L instead of 540-1527L. Plus, there’s no spare tyre, with just a tyre repair kit fitted.

These aside, the iX1’s spacious and inviting interior remains one of the compact SUV segment’s best.

Measuring 5243mm, 2030mm wide and 1782mm tall with a 3135mm wheelbase, the GLS63 is an upper-large SUV in every sense of the term, which means it’s also very practical.

For example, cargo capacity below the load cover is decent, at 355L, but stow the 50/50 power-split-folding third row via the boot and it’s very good, at 890L, or drop the 40/20/40 power-split-folding middle bench, too, and it becomes a cavernous 2400L.

Better yet, the boot’s aperture is almost square, and its floor’s flat, while there’s no load lip to contend with, making loading bulkier items even easier. Up to four tie-down points are also on hand (depending on seating configuration) to secure loose cargo.

Under the false floor is the space-saver spare, which is to be expected, but what isn’t expected necessarily is the fact there’s also enough room there for the cargo cover when it’s not in use, which would be the case if six or more passengers are regularly onboard.

Moving into the power-sliding second row, the GLS63’s practicality is once again brought to the fore, with up to six-plus inches of legroom available behind my 184cm driving position.

There’s also two inches of headroom with the panoramic sunroof in situ, not to mention just enough toe-room. The GLS63’s small transmission tunnel and sheer width also mean three adults can be seated on the middle bench with few complaints.

Amenities-wise, the second row has map pockets on the front-seat backrest and a small fold-down cubby below the rear climate controls, with it containing two slots for smartphones and a pair of strategically placed USB-C ports.

The rear door bins can take one large bottle each, while a fold-down central armrest is also on hand, featuring a shallow tray and retractable (and flimsy) cupholders.

Alternatively, the $2800 Rear Seat Comfort Package fitted to our test vehicle subs in a tablet that can control the multimedia system, a wireless smartphone charger and a small cubby into the former, as well as a heated/cooled cupholder atop the rear of the centre console.

In the third row, it’s not quite as roomy if you’re an adult. With the middle bench in its most accommodating position, my knees still brush up against its backrest, which is to be expected given it’s primarily designed for children. I also have an inch of headroom there.

Nonetheless, getting in and out of the third row is relatively easy as the power-operated middle bench tumbles forward and provides just enough space to make entry and exit somewhat graceful.

When seated, rear occupants are treated to two USB-C ports and one small cupholder each, so they’re arguably taken better care of than those in the middle.

Child seats are well and truly accommodated, with four ISOFIX and five top-tether anchorage points fitted across the second and third rows, although the latter will inevitably prove to be a much tighter fit.

The driver and front passenger are still taken care of, with a front cubby taken up by two heated/cooled cupholders, a wireless smartphone charger, two USB-C ports and a 12V power outlet, while their door bins take one large and one small bottle each.

In-cabin storage options include the large central storage bin, which hides another USB-C port, while the glovebox is on the smaller side, with about a third of it taken up by the fragrance, which is pumped into the cabin to ensure the interior always smells its best.

Priced from $255,700 plus on-road costs, the GLS63 commands a $34,329 premium over its predecessor, although buyers are arguably getting more bang for their buck than before, even if it does sit well clear of the two other GLS variants: the $147,100 GLS450 and $153,900 GLS400d.

Standard equipment not already mentioned in the GLS63 includes regular metallic paintwork (our test vehicle was finished in Selenite Grey), dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, soft-close doors, roof rails, rear privacy glass and a power-operated tailgate.

Inside, keyless entry and start, augmented reality (AR) satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, a head-up display, a panoramic sunroof, heated seats (including middle outboard) and armrests, cooled front seats with massaging functionality, power-adjustable seats, a power-adjustable steering column, temperature-controlled front cupholders, five-zone climate control, stainless-steel pedals and an auto-dimming rearview mirror feature.

With BMW not offering an X7 M (although the slightly smaller $209,900 X5 M Competition is available) and the $208,500 Audi RS Q8 really from the segment below, the GLS63 does not have a direct rival in the Upper-large SUV segment.

In fact, the $334,700 Bentley Bentayga V8 is actually the model that comes closest to the GLS63 when looking for a seven-seater with a similar level of bent-eight performance.

The iX1 boasts BMW’s fifth-generation EV drive system, known as eDrive 5.0 (M170SF).

Being an xDrive30, there are two electric motors fitted – one on each axle to provide all-wheel drive. Both are electrically excited synchronous motor set-ups.

Drive is predominantly to the front wheels via a single-speed reduction gear transmission, unless extra traction is required, in which case the rear motor kicks in to power the back axle.

Combined with the aid of an overboost function, they deliver 230kW of power and 494Nm of torque, for a 0-100km/h sprint time of 5.6 seconds, on the way to a 180km/h top speed.

Tipping the scales at 2010kg, the xDrive30 provides a power-to-weight ratio of 114kW per tonne, which is a healthy number.

Suspension is via MacPherson-style struts up front and an independent three-link design out back.

If you care, towing limits are 1200kg braked and 750kg unbraked, with a 570kg maximum payload.

The GLS63 is powered by a familiar 4.0-litre twin-turbo V8 petrol engine, with its version producing a thumping 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

This unit is mated to a nine-speed torque-converter automatic transmission and AMG’s fully variable 4Matic+ all-wheel-drive system with torque vectoring and a rear limited-slip differential.

This set-up also features Mercedes’ EQ Boost 48V mild-hybrid system, which actually gives a 16kW/250Nm electric boost in short bursts, such as when accelerating off the line.

Speaking of which, the GLS63 sprints from a standstill to 100km/h in just 4.2 seconds, while its top speed is electronically limited to 250km/h.
 

BMW says the xDrive30 consumes an average of 18.3kWh/100km.

On the launch drive program, the vehicle displayed 21.3kWh/100km. That included some spirited highway and mountain-road driving conditions.

Fitted with a 67kWh lithium-ion battery pack with a useable 65kWh, the iX1 offers an ADR 81/02-rated range of 400km.

This means a relatively common 50kW DC public charger with a CCS Combo 2 socket will need about 65 minutes to replenish the battery from 10 to 80 per cent or about half an hour with a 150kW charger.

If neither are available, you'll require about 34 hours to charge to 100 per cent maximum using the normal household powerpoint plug. Or, as mentioned earlier, a 22kW AC Wallbox cuts that down to about 3.5 hours.

Each iX1 includes a three-year subscription with Chargefox.

The GLS63’s fuel consumption on the combined-cycle test (ADR 81/02) is 13.0L per 100km, while its carbon dioxide emissions are 296 grams per km. All things considered, both claims are unsurprisingly high.

In our real-world testing, we averaged a fearsome 18.5L/100km over 65km of driving, split between highways and country roads, so not your usual mix. A very heavy right foot definitely influenced that result, but don’t expect to do too much better in a normal run.

For reference, the GLS63’s 90L fuel tank can be filled up with 98RON petrol at a minimum.

One of the best things about the iX1 xDrive30 is that it has just enough EV smoothness, refinement and speed to feel special, yet still drives and behaves as a BMW should.

Which hasn't always been the case with previous-gen X1s.

It helps that, from the driver’s seat, everything falls into place: the bracing seats, thoughtfully positioned relative to all controls; and the overall sporty/quality ambience that puts you into the brand mindset.

Select Drive, and the iX1 leaps away sweetly and silently, accompanied by an electric motor whir that's quite pleasing. At speed, acceleration is instant for fast overtaking and there’s plenty more in reserve if you really need to hustle along.

For a 2.0-tonne compact SUV, the steering is remarkably responsive, providing nimble yet secure handling. Maybe it’s all the low-slung weight and near-50:50 weight distribution, but the iX1 displays impressive cornering and road grip. It’s an enjoyable drive.

Initially, novices might find the brakes a bit sudden, but they’re actually pretty progressive once you get used to them, and they feel and stop with a more natural pedal feel than many hybrids we’ve experienced. Again, BMW has tuned the xDrive30 to feel inclusive.   

Speaking of the stoppers, there are no paddle shifters to control the amount of single-pedal off-accelerator braking as per many other EVs, but putting the transmission from ‘D’ to ‘B’ brings a decent level of deceleration if not a full stop – as if you’re lighting resting your foot on the pedal. We’d like the option of a heavier self-braking function, though.

The launch program avoided city roads and heavy traffic, but we still found plenty of bad, pot-holed surfaces to favourably judge the adaptive dampers’ ability to help soak up the bumps.

While not super-soft or supple, the suspension is cushy enough for a comfy ride. And certainly better than many past BMW SUVs.

A bit too much road and tyre noise intrusion aside, the xDrive30 is dynamically very sorted indeed.

Which, when you consider all the other positive aspects of the iX1, you end up with a BMW offering an impressively broad band of capabilities.

It’s rapid, nimble and reactive to driver inputs, as you’d expect an SUV from this brand to be, without the compromise of harshness or discomfort.

What it’s like around town in a peak-hour crawl, or how far you can really get from a fully-charged battery, is something we’ll find out when we can conduct a full road test, so please watch this space.

Until then, as it stands, things are looking promising indeed for the xDrive30. Especially factoring in the value pricing.

Frankly, the GLS63 has absolutely no right being as capable as it is. It’s a really big bus that’s legitimately convinced it’s a sports car half its size.

Being a GLS variant, the GLS63 has independent suspension consisting of four-link front and multi-link rear axles with air springs and adaptive dampers, but its party trick is the addition of active anti-roll bars.

In what feels like magic, the GLS63 is simply not intimidated by corners, despite having massive dimensions and a considerable 2555kg (kerb weight) to deal with.

The active anti-roll bars make the GLS63 so much easier to drive fast through the twisty stuff, almost eliminating body roll, taking one key variable out of the equation for the driver. Active engine mounts are also fitted, helping to settle things even further.

The electric power steering on hand is also good. It is speed-sensitive and has a variable ratio, which basically makes the set-up more direct when it needs to be. It’s typically light in hand, too, until one of the sportier drive modes is engaged and extra heft is added.

So, handling is scarcely believable, which means the ride must be compromised, right? Yes and no. With the adaptive dampers in their softest setting, the GLS63 is very compliant. In fact, we’d say it feels luxurious when compared to other high-performance SUVs.

That said, our test vehicle was fitted with the optional 23-inch alloy wheels ($3900), which look the part but expose sharp edges and other road imperfections, not to mention generate noise easily heard inside. Naturally, feedback is exacerbated in the sportier drive modes.

Anyway, there’s more performance, and the GLS63 has the rest in spades. Its engine is a powerhouse in every sense of the word. It’s so powerful, in fact, that it hilariously hunkers down off the line or when suddenly accelerating at low speed.

Thanks to the mild-hybrid system, wads of torque is available from the get-go, making for a highly responsive driving experience, even in those rare moments when the engine isn’t on song.

While not as characterful as some of the other members in the 63 series, the GLS63 still makes some thoroughly entertaining noises, with its sports exhaust system popping like mad while on the overrun.

All of this ability is very well and good, but you need to be able to pull up quickly, and the high-performance braking package (400mm front and 370mm rear discs with six-piston fixed callipers and single-pot floating stoppers respectively) mercifully does exactly that.

Neither ANCAP nor its European counterpart, Euro NCAP, have awarded the GLS range a safety rating, but it’s fair to assume it would perform well in testing.

Advanced driver-assist systems in the GLS63 extend to autonomous emergency braking with pedestrian and cyclist detection, lane-keep and steering assist (including emergency), adaptive cruise control, active blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, high-beam assist, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, surround-view cameras and front and rear parking sensors.

Other standard safety equipment includes nine airbags (dual front, front-side, curtain and rear-side plus driver’s knee), anti-skid brakes (ABS), electronic brake-force distribution (EBD) and the usual electronic stability and traction control systems. Yep, it doesn’t leave much to be desired on the safety front.

Last year, BMW introduced a five-year/unlimited kilometre warranty with all its products, finally catching up with the industry warranty average after a protracted period of just a three-year coverage.

While there’s no capped-price servicing, you can pre-purchase a number of service bundles, to help save a bit more money further down the track.

There's a choice of 'Basic' or 'Plus' packages, in four or six-year (both with unlimited kilometre) programs, known as 'Service Inclusive'. They cost $1263/$4784 and $1800/$5784, respectively. 'Plus' covers brake pads/discs and wiper blade rubbers.

Note, however, that roadside assistance remains at three years.

Keep in mind, too, that BMW vehicles have a self-diagnosis feature that varies the service intervals according to how they’re used as well as wear and tear.

Our advice is to keep making an appointment annually or at about every 10,000km, just to be on the safe side.

As with all Mercedes-AMG models, the GLS63 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.

The GLS63’s service intervals are relatively long, at every 12 months or 20,000km (whichever comes first). Better yet, it’s available with a five-year/100,000km capped-price servicing plan, but it costs $4450.
