Mercedes-Benz GLB-Class vs Peugeot 5008

What's the difference?

It’s easy to say the GLB35 doesn’t deserve to be called an AMG when looking at its credentials on paper, but get behind the wheel and it’s evident Affalterbach played a key role in making it feel as special to drive as it should be.

The GLB35 has all of the great qualities of the GLB250 and other GLB variants, but successfully adds a performance focus to make for an even more compelling package.

Indeed, the GLB35 proves you can pretty much have it all.

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.

With the boxy and therefore rugged-looking GLB laying some great foundations, it’s no surprise the GLB35 looks pretty damn good – to these eyes, at least.

Being an AMG model, it stands out from the crowd with an aggressive body kit, with the chunky bumpers, aerodynamic roof spoiler and racy rear diffuser all unique alongside the now-signature Panamericana grille insert.

A set of 20-inch alloy wheels with 255/40 tyres ups the ante at the side, where the carryover black plastic wheel-arch and skirt cladding serves as an obligatory reminder that this is an SUV.

Also of note are the nicely designed LED headlights and tail-lights, which literally light the way, but there’s no getting past the bespoke diffuser element, which integrates the sports exhaust system’s dual 90mm tailpipes.

Inside, the GLB35 is a technological tour de force, with a pair of 10.25-inch high-resolution displays proudly sitting side by side atop the dashboard, with one the central touchscreen and the other the digital instrument cluster.

Both are powered by Mercedes-Benz’s MBUX multimedia system, which arguably remains the best there is today thanks its speed and breadth of functionality and input methods.

The GLB35 is also properly premium. Lugano leather upholstery covers the seats and armrests, while Nappa trims the sports steering wheel. Even the door shoulders and inserts get ‘cow hide’, although theirs is of the artificial variety.

Soft-touch materials are used for the upper dashboard, leaving hard plastics to the lower sections, which is what you’d expect for the price.

While the black headliner makes for a dark cabin, brightness comes from the metallic trim used throughout, notably on the steering wheel, dashboard, doors and centre console. And let’s not forget the pop of colour provided by the addictive ambient lighting.

And mercifully, scratch- and fingerprint-hungry gloss-black accents are limited to the surrounds of the turbine-style front air vents, dual-zone climate controls and centre console.

Unique to the GLB35 are Carbon Structure trim and stainless-steel sports pedals, just in case you forgot you weren’t driving a regular GLB.

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!

Measuring 4650mm long (with a 2829mm wheelbase), 1845mm wide and 1660mm tall, the GLB35 is more like the GLC43 in size than the GLA35, making it a mid-size SUV despite its small underpinnings. And that is good news for practicality.

Cargo capacity with the 50/50 split-fold third row stowed is more than solid, at 565 litres (VDA), but it can be increased to a cavernous 1800L with the 40/20/40 split-fold middle bench also not in use. If six or seven passengers are onboard, though, there’s very little room to move.

Nonetheless, the boot is still well packaged, featuring a huge aperture, no load lip, and a flat floor, which make loading and unloading bulkier items a hell of a lot easier. And even the load cover can be stored underfloor when out of action. How good.

There are also four tie-down points, two bag hooks, a side storage net and a 12V power outlet on hand to make matters even easier, while the rear seats can be stowed from the boot.

While we’re on the topic, Mercedes-Benz says the third row can accommodate passengers up to 168cm tall, with the middle bench able to slide fore and aft by up to 140mm.

Yes, I'm too tall, at 184cm, but I can still sit in the very back, although not in total comfort. All in all, about a centimetre of legroom and negligible headroom and toe-room are on offer there for me.

That said, getting in and out in the first place is the real challenge here, with the middle bench unable to tumble forward for easy ingress and egress. Yep, you’re not going to look smooth either way. Children can deal with it, but adults won’t be thrilled.

Therefore, the middle bench is the place to be, even when it’s slid all the way forward. Behind my driving position, it offers about a centimetre of legroom, but this can be increased to several inches by sliding it all the way back.

Either way, plenty of toe-room is available alongside more than an inch of headroom. The latter is more impressive when you consider that’s what you get with the standard dual-pane panoramic sunroof fitted.

Even better, the second row can seat three adults at a pinch, partly thanks to the low transmission tunnel, which means there’s the right amount of space for six fully grown feet across the two footwells. It goes without saying children will again be fine.

Speaking of which, four ISOFIX and five top-tether anchorage points are on hand for fitting up to four child seats across the second and third rows, which makes the GLB35 a serious option for families that like to be sporty.

There are plenty of in-cabin storage options, with the large central storage bin featuring a pair of USB-C ports, while the glovebox is also quite useful, even if it is oddly shaped. And there’s also a sunglasses holder in front of the rearview mirror.

The centre console’s cubby isn’t really designed for storage, with it basically taken up by two cupholders, another USB-C port and a wireless smartphone charger.

The front door bins can accommodate one small and two regular bottles each, which is great, while their rear counterparts can take one small and one regular apiece.

Second-row occupants also have access to a fold-down armrest with another pair of cupholders, but being of the retractable variety, they’re flimsy.

These passengers also have two USB-C ports, with the pair folding out below a small cubby and air vents, which are found at the back of the centre console. Storage nets are also fitted on the front seat backrests.

And don’t worry; the third row gets in on the action, with two cupholders (one regular, the other small) splitting the seats, which have individual USB-C ports and device straps to the sides.
 

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 GLB35 is powered by an uprated version of the GLB250’s 2.0-litre turbo-petrol four-cylinder petrol engine, with the AMG-fettled version producing a more substantial 225kW of power from 5800-6100rpm and 400Nm of torque from 3000-4000rpm (up from 165kW/350Nm).

This version is also matched to an eight-speed dual-clutch automatic transmission as well as Mercedes-AMG’s front-biased but fully variable 4Matic all-wheel-drive system.

Thanks to this combination, the GLB35 can sprint from 0-100km/h in just 5.2 seconds with launch control enabled, while its electronically limited top speed is 250km/h.

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 GLB35’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.3L per 100km, while its carbon dioxide emissions are 186 grams per km. All things considered, both claims are pretty decent.

In our real-world testing, though, we averaged a high 14.1L/100km over 75km of driving split between highways and country roads, so not your typical mix, then. A heavy right foot also played into that result, so expect a better return after a regular run.

For reference, the GLB35’s 60L fuel tank can be filled up with 98RON petrol at minimum.

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.

Don’t let the GLB35’s family friendliness fool you, this is an SUV that can get up and go.

The engine’s extra power and torque over the GLB250 are immediately felt behind the wheel, with the GLB35 accelerating with the vigour of an all-wheel-drive hot hatch, which makes sense given their similar claims.

And if you have one of the sportier drive modes engaged, the booming noise generated is also special – even if a lot of it is of the artificial variety, pumped into the cabin to make occupants feel like things are getting serious.

What is genuine, though, is the well-rounded transmission, which is characteristically quick with its upshifts. At the same time, it’s also relatively smooth, even at low speed, which has proven to be a challenge for dual-clutch units over time, but not here.

To earn the AMG badge, the GLB35 goes even further with other mechanical upgrades, including sports tunes for the suspension and steering.

Specifically, the GLB35’s independent suspension set-up not only consists of MacPherson-strut front and trailing-link rear axles with adaptive dampers, but also introduces new steering knuckles, transverse control arms on the front axle, and a stiffened subframe.

The resulting ride is actually quite good. Yes, the extra firmness over the GLB250 is noticeable – particularly in the sportier drive modes that stiffen the adaptive dampers all the way – but it’s by no means a deal-breaker.

That said, it’s worth noting our test vehicle was fitted with the optional 21-inch alloy wheels ($1990), so the GLB35’s like to ride even better on its standard package.

This is remarkable considering the handling improvements made, with the GLB35 managing body roll and pitch better than the GLB250 when pushing hard into and around corners, coming out of which grip is plentiful thanks to the all-wheel-drive system.

Thankfully, the standard-fit high-performance braking package consisting of 350mm front and 330mm rear discs with four- and one-piston callipers respectively helped it wash speed away with ease when attacking the twisty stuff with intent, even with 1857kg (kerb) to deal with.

Also on hand is electric power steering, which is speed-sensitive and has a variable ratio in the GLB35. Basically, it’s quicker when you want it to be, remaining on the lighter side in hand until you engage one of the sportier drive modes and weight is increased markedly.

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.

As with all Mercedes-AMG models, the GLB35 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 GLB35’s service intervals are long, at every 12 months or 25,000km (whichever comes first). Better yet, it’s available with a three-year/75,000km capped-price servicing plan, but it costs $2750, with the third visit alone incurring a $1300 charge.

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.
