Mercedes-Benz GLS vs Ferrari 488

What's the difference?

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 Ferrari 488 Spider is a brilliant machine. It's properly supercar fast, in a straight line and around corners. It looks stunning, and attention to design detail, engineering refinement and overall quality oozes from its every pore.

Is it the best car I’ve ever driven? Close, but not quite. Others may disagree, but for what it’s worth, I think the Ferrari 458 Italia, in all its high-revving, naturally aspirated glory is still the sweetest ride of all.

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.

Launched in 2015, the 488 is the fourth mid-engine V8 Ferrari based on the aluminium space-frame architecture unveiled with the 360 Modena back in 1999, and unlike its Pininfarina-penned predecessors, was designed in-house at the Ferrari Styling Centre, under the direction of Flavio Manzoni.

The key focus this time around was aero performance, including the additional breathing and cooling needs of the 488’s 3.9-litre twin-turbo V8 (relative to the 458’s 4.5-litre naturally aspirated unit); hence the car’s most obvious visual identifiers - substantial air intakes in each flank.

Measuring 4568mm nose-to-tail, and 1952mm across, the 488 Spider is marginally longer (+41mm) and wider (+15mm) than its 458 equivalent. That said, it’s exactly the same height at just 1211mm tall, and the 2650mm wheelbase is unchanged.

Ferrari is a past master when it comes to sneaky concealment of spectacular aero trickery, and the 488 Spider is no exception.

Inside, the design is all about simplicity and focus for the person with the steering wheel in their hands.

Upper elements of its F1-inspired double front spoiler direct air to the two radiators, while the larger lower section subtly pulls flow under the car where carefully tuned ‘vortex generators’ and a yawning rear diffuser (incorporating computer-controlled, variable flaps) dial up downforce without a significant drag penalty.

The ‘blown’ rear spoiler manages air from intakes at the base of the rear screen, its specific geometry allowing a more pronounced (concave) profile for the main surface to increase upward deflection and maximise downforce without the need for an oversize or raised wing.

Those side intakes are divided by a central, horizontal flap, with air from the upper section directed to exits over the tail, pushing the low-pressure wake directly behind the car further back to again reduce drag. Air flowing into the lower section is sent to the turbo engine’s air-to-air intercoolers to optimise intake charge. All brilliantly efficient and tastefully incognito.

Putting the engine in the centre of the car and fitting only two seats doesn’t just pay off dynamically, it delivers the perfect platform for visual balance, and Ferrari has done a superb job of evolving its ‘junior supercar’ with a nod to the line’s heritage and an eye on extending its reach.

The tension across its multiple curved and contoured surfaces is beautifully managed, and the Spider’s crouching stance screams power and single-minded purpose.

Inside, while the passenger might be enjoying the ride, the design is all about simplicity and focus for the person with the steering wheel in their hands. 

To that end, the slightly angular wheel houses a host of controls and displays including a very red start button, driving mode ‘Manettino’ dial, within-thumb’s-reach buttons for indicators, lights, wipers and ‘bumpy road’ (more on that later), as well as sequential max rpm warning lights across the top of the rim.

The steering wheel, dash, doors and console are (optionally) carbon-rich, with the familiar buttons for Auto, Reverse and Launch Control, now housed in a dramatic arching structure between the seats.

The compact instrument binnacle is dominated by a central rev-counter with digital speedo inside it. Readout screens for on-board info across audio, nav, vehicle settings, and other functions sit either side. The seats are grippy, lightweight, hand-crafted works of art, and the overall feeling inside the cockpit is an amazing mix of cool functionality and special event anticipation.

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.

Okay, so how do you approach practicality in a car that’s so obviously not engaged with the concept?

Best to say there’s cursory consideration in terms of cabin storage, with a modest glovebox, small pockets in the doors, and a pair of piccolo-sized cupholders in the console. There’s also a net and some general oddments space along the bulkhead behind the seats. 

But the saving grace is a generous, rectangular boot in the nose, offering 230 litres of easy-to-access load space.

Another attribute fitting broadly under the heading of practicality is the retractable hardtop which smoothly unfolds/retracts in just 14 seconds and operates at speeds up to 40km/h.

Let’s get the big number out of the way. The Ferrari 488 Spider costs $526,888 before on-road costs.

Included in that not inconsequential figure is the ‘E-Diff3’ electronically-controlled differential, ‘F1-Trac’ traction control, ASR & CST, ABS, an anti-theft system, carbon-ceramic brakes, Magnaride shock absorbers, dual-zone climate control, racy leather seats, bi-xenon headlights with LED running lights and indicators, keyless start, Harman multimedia (including 12-speaker, 1280-watt JBL audio), 20-inch alloy rims, tyre pressure and temperature monitoring, and… a car cover.

But that’s just the starting point. Any self-respecting Ferrari owner will need to put a personal stamp on their new toy and the prancing horse is happy to oblige.

If you want an exterior colour to match your favourite polo pony’s eyes, no problem, the Ferrari Tailor-Made program will do whatever it takes. But even the standard options list (if that makes sense) offers more than enough scope to make an already spectacular four-wheel statement even more distinctive.

Our test car featured six new Mazda3’s worth of extras. That’s just under $130k, with the highlights being more than 25 grand in exterior carbon-fibre, $22k for the special, two layer, iridescent effect ‘Blue Corsa’ paint, over $10k for chrome painted forged rims, and $6790 for Apple CarPlay (standard on the Hyundai Accent).

But you’ve got to remember an inverse logic applies here. While some may see $3000 for cavallino rampante shields on the front wings as somewhat pricey, to a proud Ferrari owner they’re badges of honour. In the yacht club carpark, showing off their latest acquisition, you can script the satisfied boast - ‘That’s right. Two grand. Just for the floor mats!’

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.
 

The 488 Spider is powered by an all-alloy, mid-mounted 3.9-litre, twin-turbo V8, featuring variable valve timing and dry sump lubrication. Claimed outputs are 492kW at 80000rpm and 760Nm at a usefully low 3000rpm. Transmission is a seven-speed 'F1' dual clutch driving the rear wheels only.

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.

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.

We had the rare opportunity of driving the 488 Spider on road and track with Ferrari Australasia handing us the keys for a rural run from Sydney to Bathurst, followed by some private bonding time on the roads around town, then a batch of unrestricted hot laps on the Mount Panorama circuit in the lead up to this year’s 12 Hour race (which the scuderia won in emphatic style with the 488 GT3).

On the freeway, cruising at 110km/h with roof open, the 488 Spider is civilised and comfortable. In fact, Ferrari claims normal conversation at speeds over 200km/h isn’t a problem. Top tip (no pun intended) is to keep the side glass and small electric rear window raised to minimise turbulence. With the roof up, the 488 Spider is every bit as quiet and refined at the fixed roof GTB.

The 458 Italia atmo V8’s rising fortissimo howl is one of the world’s greatest mechanical symphonies.

Even with the multi-mode Manettino in its regular ‘Sport’ setting and the seven-speed ‘F1’ dual-clutch gearbox in auto, all it takes is a gentle crank of the right ankle to despatch pesky road users with the temerity to impede the 488’s progress.

On the quiet, open and twisting roads around the outskirts of Bathurst we may have flicked the switch to ‘Race’, slipped the gearbox into manual and given the 488 Spider a nudge. In some sweeping corners on Mount Panorama we might have even tested Einstein’s theory that matter bends the fabric of space and time. In short, we were able to get a good feel for the car’s dynamic abilities, and they are monumental.

Relative to the 458, power is up a lazy 17 per cent (492 v 418kW), and turbo-fed torque leaps a staggering 41 per cent (760 v 540Nm), while kerb weight is trimmed by 10kg (1525 v 1535kg).

The result is 0-100km/h in 3.0 seconds (-0.4sec), 0-400m in 10.5 (-0.9sec), and a maximum velocity of 325km/h (+5km/h).

If you must know, given fuel efficiency and emissions performance was the key driver behind Ferrari’s move to a turbo powerplant, all this is balanced by claimed 11.4L/100km combined economy (down from 11.8 for the 458).

A full blown launch in this car is like lighting the wick on an Atlas rocket, with a seemingly never-ending surge of thrust pinning your back to the seat, and each pull of the column-mounted carbon gear paddle delivering a seamless and near instantaneous shift. Ferrari claims the 488’seven-speed ‘box shifts up 30 per cent quicker, and down 40 per cent faster than the 458’s.

The lofty summit of the twin turbo’s torque mountain arrives at just 3000rpm, and once you’re up there it’s a table top rather than a peak, with more than 700Nm still on call at close to 7000rpm.

Maximum power arrives at 8000 (perilously close to the V8’s 8200rpm rev ceiling), and the delivery of all this brute force is impressively refined and linear. To improve throttle response, the compact turbos incorporate ball-bearing-mounted shafts (rather than the more common sleeve bearing type), while the compressor wheels are made from TiAl, a low-density titanium-aluminium alloy. As a result, turbo lag simply isn’t in the 488’s vocabulary.

And what about the sound? On its way to 9000rpm the 458 Italia atmo V8’s rising fortissimo howl is one of the world’s greatest mechanical symphonies.

Maranello’s exhaust engineers allegedly spent years fine-tuning the 488’s aural output, developing equal length tubes in the manifold to optimise harmonics before gas flow reaches the turbos, to get as close as possible to the high-pitch wail of a naturally aspirated Ferrari V8. 

All we can say is the 488’s sound is amazing, immediately turning heads on contact... but it ain’t no 458.

Using the 488 Spider’s incredible dynamic ability to translate forward momentum into lateral g’s is one of life great pleasures.

Supporting the double wishbone front and multi-link rear suspension set-up is a host of high-tech widgets including the tricky E-Diff3, F1-Trac (stability control), High-Performance ABS with Ferrari Pre-Fill, FrS SCM-E (magnetorheological shock absorbers), and SSC (side-slip control).

Combine that with the active aero quietly turning the car into a four-wheel suction cup, plus ultra-high performance Pirelli P Zero rubber, and you have amazing grip (the front end especially, is incredible), perfect balance and stunning corner speed.

Our Mount Panorama blat confirmed the 488 Spider remains poised and throttle steerable through corners and curves at ludicrous speeds.

Chasing gears into the top of the ‘box up mountain straight made the lights on the upper rim of the steering wheel look like a fireworks display. The Spider transmitted its every move across the top of the circuit through the lightweight seat, and the very fast blast into The Chase at the bottom of Conrod Straight was other-worldly. Set the car up on entry, keep squeezing the throttle, grease in just a fraction of steering lock, and it just blazes through like a high-speed hovercraft, at 250km/h-plus.

More time back outside Bathurst confirms feel from the electro-hydraulic rack and pinion steering is brilliant in the real world, although we did notice the column and wheel shaking in our hands over bumpy backroads.

The quick fix there is a flick of the ‘bumpy road’ button on the steering wheel. First seen on the 430 Scuderia (after then Ferrari F1 hero Michael Schumacher pushed for its development), the system de-links the shock absorbers from the Manettino setting, providing extra suspension compliance without sacrificing engine and transmission response. Brilliant.

Stopping power comes courtesy of a ‘Brembo Extreme Design’ system derived from the LaFerrari hypercar, which means standard carbon-ceramic rotors (398mm front, 360mm rear) clamped by massive calipers - six piston front, four piston rear (our car’s were black, for $2700, thank you). After multiple stops from warp speed to walking pace on the circuit they remained firm, progressive, and hugely effective.

In terms of active safety the various driver aids mentioned above do their part to avoid a crash, and if the worst comes to worst dual front and side airbags are in place.

The 488 Spider has not been rated for safety performance by ANCAP.

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.

The Ferrari 488 Spider is covered by a three year/unlimited km warranty, and purchase of any new Ferrari via the authorized Australian dealer network includes complimentary scheduled maintenance, through the ‘Ferrari Genuine Maintenance’ program for the first seven years of the vehicle’s life.

Recommended maintenance intervals are 20,000km or 12 months (the latter with no km restrictions).

Genuine Maintenance attaches to the individual vehicle, and extends to any subsequent owner within the seven years. It covers labour, original parts, engine oil and brake fluid.
