Porsche Macan vs Mercedes-Benz GLS-Class

What's the difference?

There is no doubting the substance of the Porsche Macan Electric. Its ride, steering and poise make it a joy to drive on twisting roads, and it ticks the practicality boxes, too.

The only lingering question is whether enough people are ready to make the all-electric switch. Only then will we know if Porsche's Macan gamble has paid off.

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

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…

The Macan Electric looks sharp, all aerodynamic and swept-back like a range-maximising electric SUV should.

There’s functional method behind all this swoopy styling, too. The headlights look as though they’ve been chiselled into the body work, and at the grille, you’ll find active venting to help with cooling when needed.

There is also a sizeable front splitter that looks very much like the Macan is sticking its jaw out. All of which is to assist with aero and range.

It’s also a dual charging port layout with access left and right, though the latter is AC charging only, while the one on the left does both.

Step inside the Macan and you’ll find a familiar and very welcoming space. I especially like the twin-screen set-up that looks great in the way it's kind of embedded into the dash. Each is big, clear and easy to use.

I also really like the control panel that gives you quick-button access to the climate control, and the haptic feedback is next level, with the whole screen clicking in or out whenever you hit a button.

That said, in Turbo-guise you’re dropping almost $200,000, and some of the materials feel too hard and plasticky at that price point.

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.

There is a little open-sesame magic at play with the Macan, and that starts at the frunk, where, if you lovingly caress the bonnet, it will automatically pop open for you, revealing an 84-litre storage space.

Rubbing the charging port will see it slide open, too, but just in case you’re not the kind of person who likes to fondle their car in public, you can use the key.

The Macan’s boot is a little more traditional, opening to reveal 540 litres (but just 480 litres in the 4S or Turbo) of storage with the rear seats in place, with a wide, flat and very useable area for your goodies.

The back seat of the Macan feels spacious enough, without being outstanding. There’s more than enough space for my 175cm frame, with enough knee and head room, but the way the middle console juts out will definitely eat into leg room for any middle-row passenger.

Elsewhere you get air-con controls with vents, along with bottle storage in each of the doors. There is also a pull-down divider that’s home to two extra cupholders.

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 entry-level Macan is equipped with a single rear-mounted electric motor, and it will make a total 250kW (265kW with launch control activated) and 563Nm, which is enough to push the cheapest Macan to 100km/h in 5.7 seconds.

The 4 then adds a second electric motor for AWD, upping the grunt to 285kW (300kW with the launch function) and 650Nm, and drops the sprint to a brisk 5.2 seconds.

The 4S is probably the performance sweet spot, with its dual-motor set-up generating 330kW (380kW in launch) and 820Nm, and a blistering sprint of just 4.1 seconds.

But the Macan Turbo is a true monster. We’re talking 430kW (470kW with launch control), 1130Nm and a sprint to 100km/h that’s as fast as a Carrera Cup race car – just 3.3 seconds.

It’s twin-motor, all-wheel drive and offers the kind of brutal acceleration that gives you a little facelift every time you step on the accelerator.

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.
 

Every Macan is fitted with a big 100kWh lithium-ion battery, which helps deliver a solid driving range no matter which one you choose.

The entry-level Macan will cover the most distance, at a claimed 654km, while the 4, 4S and Turbo will travel 624km, 619km and 616km, respectively.

The Macan rides on an 800V architecture, and is set up for 270kW DC high-speed charging, which will take 21min to go from 10 to 80 per cent. It will also accept 11kW AC charging, which should take 10 hours to go from empty to full.

Worth noting, though, that most home wall boxes are around 7.0kW, which means a full charge would take more like 13 hours plus.

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.

Porsche seemed at pains to prove that, though the all-electric Macan has lost its ICE heart, it's still worthy of the badge, and still very much a Porsche.

First stop, then, was the Norwell race circuit in Queensland, to put the Macan through its paces with 0-100km/h sprints, drifting (well drift attempts... ) on a watered-down skid pan and finally some high-speed running on the circuit.

And two things immediately became very clear. The first, and most obvious, was that, like the first men on the moon, we were likely among only a handful of people that might ever take their all-electric Porsche mid-size SUV to a race track. And second, this is one seriously sorted electric car.

Happily, for the many (read: every) owners who won't be pulling out of a pit garage at their next local track day, the Macan is actually more enjoyable on the road than it is on the track.

On the latter, there's a freedom to push too hard – what with the lack of trees, guard rails or oncoming traffic – and cracks do appear, mostly from the screaming tyres struggling with the two-tonne-plus weight.

But on public roads, where a thick fog of consequence prevents you pushing too hard, the Macan is a gem.

Porsche tends to have a knack for these things, I know, but the Macan is a seriously smooth and satisfying drive.

The ride is bang-on (comfortable enough on rougher surfaces, firm and grippy enough on twisting roads) and the steering is direct and confidence-inspiring.

Body-roll has been largely banished, too, with the Macan staying flat, stable and satisfying, even on the tighter stuff.

In much the same way the ICE Macan defined what it meant to be a driver's SUV, I think this one does the same in the EV space. And the fact that it does it with five seats and a decent boot is a sizeable bonus.

But there's no denying it lacks in the emotion department. That sense of excitement, the sound track, the hard-to-define fizz – as competent its this, and as weaponised as the EV powertrain is – it does feel a little clinical, like a tool doing its job and doing it well.

One important caveat. We've driven the 4 and Turbo to date. The entry-level Macan and the mid-tier 4S are still incoming. And I suspect I wouldn't be dropping my deposit on the Turbo.

Yes, the power is ridiculous, but I don't reckon you need it. For me, the 4 is more than enough, but I suspect the real performance sweet spot will be with the 4S.

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.

The Porsche ownership experience is frankly underwhelming by modern standards, with the brand offering just a three-year/unlimited kilometre warranty, plus an eight-year/160,000km battery warranty.

The positive, though, is that servicing should only be required every two years or 30,000km. You also buy a prepaid service plan for three, four or five years, priced at $1495, $2795, $2995.

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.
