Peugeot 5008 vs Mercedes-Benz GLS-Class

What's the difference?

Despite its new mild-hybrid powertrain and generous list of premium features, the Peugeot 5008 GT Premium Hybrid doesn’t always hit the mark. It’s not a bad car. In fact, it’s comfortable, stylish, and well-equipped. But it sits in a highly competitive segment where some rivals offer more space, more power, or better value.

It’s not the most versatile seven-seater on the market, but it will suit families who only occasionally need that third row. And that’s the theme here. The 5008 is sufficient. It does most things well enough, but in a class full of standout options, it doesn’t quite push through to the front.

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 redesigned 5008 essentially looks like a stretched 3008, with a more squared-off rear that adds some robustness but not necessarily extra style.

It’s nice enough from most angles, but not all of them. The front, however, is a different story. With its fresh grille design and sharp pixel LED headlights, it looks striking, and the signature Peugeot ‘claw’ light motif remains; a detail fans will appreciate. The flagship grade also gets a stylised C-pillar and 19-inch alloy wheels to round out the look.

Inside is where the 5008 really shines. Trust the French to bring some dramatic flair, as the cabin is a standout. A multi-tiered dashboard and centre console are finished in a mix of grey knit fabric and Nappa leather, adding texture and elegance. Soft-touch materials are used generously, and with interesting lines and layered details, there’s always something to catch the eye.

The panoramic sunroof brightens things up during the day, while customisable ambient lighting adds wow-factor at night. That said, the pixel-style lighting strips can be a bit trippy if you stare at them too long!

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.

When it comes to functionality and practicality, the new 5008 mostly hits the right beats. The beats it doesn't hit feel more quirky than full-fledged misses, though.

The first row is the clear winner for comfort, offering electric front seats with heating, ventilation, massage functions, expandable under-thigh support and adjustable lumbar and side bolsters.

That said, the passenger seat sits too high and is angled slightly forward in its base position, which made it tricky to find a comfortable setting for a long road trip.

The middle row features three individually folding seats, though they slide in a 60/40 split. At 4791mm long, the 5008 is on the larger side of the mid-size SUV segment, and that translates to decent legroom in the second row.

However, the seats are quite firm and set in a stadium-style layout. That raised position gives passengers a good view forward but means taller occupants will find themselves close to the roofline.

Amenities in the second row are solid, including climate control, manual sun-blinds, heated outboard seats and two USB-C ports. The only letdown is the fold-down centre armrest, which is frustratingly hard to open as it doesn’t have a toggle.

The third row is strictly kid territory. Access is manageable and the space is fine for children, but don’t expect adults to enjoy the ride. Even my eight-year old noted the limited amenities and legroom back there.

Access throughout the cabin is slightly awkward as the front footwells are flush with the door sills, but that changes towards the rear where the sill and floor levels shift, making it easy to tangle feet on entry until you get used to it. However, the 231mm ground clearance means it’s easy for oldies to get in and out.

Storage is well thought out, with a large ventilated centre console, glove box, centre console bin, phone cradle and sunglasses holder up front. The second row gets two netted map pockets and a small storage cubby under the rear of the centre console. There are cupholders in the first two rows and bottle holders in every door.

Boot space is decent for a seven-seater. With all three rows in place, you get 348L which is enough for a couple of school bags or a modest grocery run.

Fold the third row down and it expands to a useful 916L. There is an underfloor storage area but it disappears underneath the third row and the little space is hard to access if something rolls back there. A powered tailgate is standard on the GT Premium, though we found it didn’t open reliably from the external button.

Technology is fairly straightforward. The media display is responsive and includes sat nav, plus wireless Apple CarPlay and Android Auto. However, the screen’s narrow, wide layout can make it easy to hit the wrong icon, and the lack of physical shortcut buttons means you’re relying heavily on the customisable on-screen panel. It didn’t bother me but my dad didn’t like it.

Charging options are good across the cabin, with USB-C ports in the first and second rows, a 12-volt socket and wireless charging pad up front and another 12-volt socket in the boot which third-row passengers can access in a pinch.

Don't bother looking for a spare of any description, a tyre repair kit is your only option.

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.

All grades of the 5008 now share the same mild-hybrid powertrain, paired with a six-speed dual-clutch auto transmission. The set-up combines a 1.2-litre, three-cylinder, turbo-petrol engine with a small electric motor and a 48-volt battery.

Together, they produce 107kW and 230Nm, making it the least powerful offering compared to its rivals.

Performance is modest, with a claimed 0-100km/h time of 11.3 seconds, so you won’t be winning any races. While there's more to consider for everyday driving than outright speed it factors into long highway trips.

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 new hybrid powertrain has a claimed combined cycle (urban/extra-urban) fuel consumption figure of 5.1L/100km. With a 55-litre fuel tank that translates to a theoretical driving range of up to 1078km, which is impressive for a seven-seat SUV.

The regenerative braking offers mild feedback but obviously helps because in real-world conditions I averaged 6.1L/100km over a week of mixed urban and open-road driving. That’s not far off the official claim and still very respectable for a family hauler of this size.

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.

You quickly learn the 5008's limits. It has enough power to get up to speed without feeling strained but there’s not much left in reserve. Overtaking is doable but not fast. It’ll get the job done, just don’t expect a burst of responsiveness once you're already cruising.

Steering has a nice, reassuring weight to it and helps you feel in control. The lane-keeping aid can be a little over-eager and tends to jiggle you around, but otherwise the driver assists don’t get in the way.

The suspension is on the firmer side, so you feel bumps on the road. That said, I never winced going over them, which speaks to how well it handles everyday surfaces.

Visibility is a strong point from the driver’s seat. The B-pillar is a little chunky, but the elevated driving position gives you a clear view through the front and sides.

You can feel the transition between the hybrid components, but it’s not jarring. However, the regenerative braking isn’t very strong. A bit more bite could help the driving experience, especially around town.

Parking is refreshingly easy. The 360-degree camera system's screen is small but clear, and the 5008’s relatively compact footprint for a seven-seater makes it easier to slot into tight spots. It’s a plus if you’re regularly navigating city streets.

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 new 5008 is backed by Peugeot’s five-year/unlimited kilometre warranty, with five years of complimentary roadside assistance included.

While that’s fairly standard, it doesn’t quite match the longer coverage offered by some rivals, with several now pushing out to seven years or more.

Servicing intervals are spaced at every 12 months or 20,000km, whichever comes first, which is generous compared to some competitors.

Peugeot also offers pre-paid service plans in three-, four-, or five-year packages. The five-year plan costs $1995, which is cheaper than paying as you go and reasonable for this class.

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.
