Mercedes-Benz G63 vs Peugeot 5008

What's the difference?

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.

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 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.

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!

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.

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.

The new 5008 line-up has been simplified to just two grades, the Allure and flagship GT Premium Hybrid, which we’re testing for this review. With a drive-away price of $73,705, it’s the most expensive top-spec, seven-seat mid-size SUV in its class.

For comparison, the Chery Tiggo 8 Super Hybrid Urban drives away at $49,990, the Mitsubishi Outlander Exceed Tourer at $63,130, and the Nissan X-Trail Ti-L e-Power at $59,990.

That higher price tag is softened somewhat by a generous list of premium features. You get Nappa leather upholstery, electric front seats (with heating, ventilation and massage functions), a panoramic sunroof, heated rear outboard seats, built-in sat nav and three-zone climate control.

New for this update is a 21-inch curved panoramic display that blends the digital instrument cluster with the central touchscreen.

You’ll also find pixel LED headlights, wireless Apple CarPlay and Android Auto, an AI voice assistant and over-the-air updates for the nav system.

Other standard features include keyless entry and start, a hands-free powered tailgate, four USB-C ports, two 12-volt sockets, a wireless charging pad, customisable ambient lighting, rear sun-blinds, a retractable cargo cover and a 360-degree camera system as well as front and rear parking sensors.

All up, the spec list justifies the GT Premium’s high-end position but make no mistake, you are paying for it.

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.

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.

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 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.

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.

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.

At the time of writing, the new Peugeot 5008 remains unrated by ANCAP, which may be a consideration for some family buyers. It also features just six airbags which is on the low side for a seven-seater but the side curtain airbags extend to the third row, which is important.

Crash avoidance tech is comprehensive and includes autonomous emergency braking, forward collision warning, blind-spot monitoring, lane departure warning, lane-keeping assist, driver attention alert, traffic sign recognition, a 360-degree camera system, front and rear parking sensors, rear cross-traffic alert, hill start assist, tyre pressure monitoring and intelligent seatbelt reminders for all seven seats.

In terms of child-seat accommodation, the second row offers two ISOFIX anchors and three top-tether anchor points.

The adaptive cruise control isn’t as well-calibrated as I’d like as it can feel a little slow to react and sometimes reacts to vehicles in side lanes. But otherwise, the safety tech works in the background without being overly intrusive.

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.

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.
