Peugeot 408 vs Mercedes-Benz GLB-Class

What's the difference?

The Peugeot 408 GT Hybrid delivers heaps of standard equipment and safety tech for what is now a much more competitive price. It’s also super fuel-efficient, which is right for these turbulent times, offers thoughtful practicality and the wagon-fastback-crossover-SUV look is striking. The price paid for miserly economy is a peaky small-engine powertrain and the ownership promise isn’t exactly class-leading. That said, it deserves consideration in its new, even more competitive under $60K mid-size SUV segment.

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.

Peugeot Design Director Matthias Hossann has been guiding the brand’s look and feel since 2020 and the result is a recognisable approach across the range with enough flexibility to give each model its own personality.

Recurring themes include the dramatic, fan-like grille with body-colour elements, narrow angled LED daytime running lights (DRLs) slicing through the outer edges of the nose and sinister tapered headlights set into the front corners.

The rear end maintains the visual drama with a stacked, angular treatment sectioning off the ‘Claw Effect’ LED tail-lights (the Peugeot brand mark is a Lion), chamfered mid-section and chunky bumper.

And among what increasingly feels like a mass of same-same newcomers the 408’s sloping turret and high, wide haunches give the car a distinctively sporty fastback look.

The interior is classy and clean although the almost uniformly grey colour palette is unrelenting.

The two-tier dash adds visual interest and a combination of sweeping curves and clean, straight lines around the cabin lift the tone. Nappa leather trim with the ribbed seat centre panels using perforated hide also looks classy.

But then we come to the ‘iCockpit’ instrument display and steering wheel combination. It’s based on the idea that reducing the size of the steering wheel and lowering its position while flattening its top and raising the location of the instrument binnacle is a better solution than the traditional look-through-the-steering wheel approach.

It doesn’t work for everyone and it doesn’t work for me. As noted in previous Peugeot reviews, after more than a decade in existence various members of the CarsGuide editorial staff continue to struggle with the arrangement, while others love it. 

For me, the wheel feels too low, yet the top of it obscures the lower part of the instrument panel. While it may work well for others I see it as the answer to a question no one was asking.

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.

At close to 4.7m long, around 1.9m wide and a bit less than 1.5m tall with a 2790mm wheelbase, the 408 sits in the middle of the typical mid-size five-seater footprint.

Ample room in the front, although the lower section of the two-tier dash protrudes a fair way towards the driver and front passenger and the centre console is broad so it feels snug rather than airy.

Storage includes generous door bins with room for larger bottles, a lidded (and illuminated) bin between the seats that doubles as a centre armrest, two cupholders in the console with an oddments tray ahead of them and a decent glove box with an extra pocket built into the lid.

Switching to the rear, sitting behind the driver’s seat set for my 183cm position, there’s loads of leg- and headroom and enough width for three adults when required and more than enough for a trio of up to mid-teenage kids. Centre rear is less of a short-straw position, too, thanks to a relatively low and flat central tunnel.

The lack of a fold-down rear centre armrest is a miss mainly because it means there are no cupholders in the rear. But there are decent door bins with a space for smaller bottles, netted map pockets on the front seatbacks and a storage cubby at the back of the front centre console.

Speaking of which, individual air vents in the back of that console are a welcome addition.

 The boot is large for the class at 508 litres (VDA) with the rear seat upright and 1583 litres with the 60/40 split-folding backrest folded down. The power tailgate (with foot sensor and pedestrian detection) also makes life easier.

Other thoughtful touches include four load tie-down anchors, a netted pocket on the right-hand side, elasticised straps on the left-hand side, specific lighting and a pair of bag hooks.

Power and connectivity options include two USB-C sockets, a 12-volt outlet and a wireless phone charging pad in the front, another two USB-Cs in the back and a second 12V plug in the boot. So no problems with charging capacity for phones and other devices.

Maximum braked trailer towing capacity is a useful 1300kg (750kg unbraked) but we have to put a big black mark against provision of a repair/inflator kit rather than a physical spare. Not good enough for the Aussie market. 

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.
 

Priced from $88,535 plus on-road costs, the GLC35 currently sits atop the GLB range, above both the $59,900 GLB200 and $73,535 GLB250.

Standard equipment not already mentioned in the GLB35 includes dusk-sensing lights, rain-sensing wipers, power-folding side mirrors, black roof rails, rear privacy glass and a power-operated tailgate.

Inside, satellite navigation with live traffic, Apple CarPlay and Android Auto support, digital radio, a 225W sound system with nine speakers, keyless entry and start, power-adjustable front comfort sports seats with heating and memory functionality, auto-dimming mirrors, illuminated ‘AMG’ scuff plates and ‘AMG’ floor mats feature.

As is commonplace for Mercedes-Benz models, the GLB35 has plenty of options with most expensive, so you could drive away with a vehicle that’s dearer than you originally thought.

But aside from a spare wheel and some safety equipment we’ll cover in a moment, the GLB35 doesn’t leave much to be desired, which is always a good thing.

Nonetheless, our test vehicle was finished in $1490 Iridium Silver Metallic paintwork, which is one of eight extra-cost exterior colour options.

As mentioned, the GLB250 is a unique proposition, so it’s only comparable rival, the more affordable but less sporty Land Rover Discovery Sport P250 HSE ($78,432).

The Peugeot 408 Hybrid is powered by a 1.2-litre, turbo-petrol, three-cylinder engine producing 100kW at 5500rpm and 230Nm at 1750rpm.

This compact, all-alloy, direct-injection unit works in concert with a single 15.6kW/51Nm 48-volt electric motor integrated into the six-speed dual-clutch auto transmission and energised by a 0.9kWh lithium-ion battery.

Drive goes to the front wheels only and Peugeot claims a 0-100kmh sprint time of 9.4 seconds.

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.

The 408 Hybrid’s official fuel consumption figure for the combined (urban/extra-urban) cycle is 4.5L/100km, the 1.2L turbo triple emitting 102g/km of CO2 in the process.

And it’s important to point out those official (ADR 81/02) numbers for the 408’s consumption and emissions are better than any of the direct competitors we’ve called out in the ‘Price & Features’ section above. 

Over a week of mainly city and suburban running with some freeway sections thrown in, we recorded an on-test average of 6.0L/100km. Impressive for a mid-size crossover weighing in at a bit over 1.4 tonnes.

Brim the 52-litre tank with minimum 95 RON premium fuel (ethanol blends not recommended) and using our real-world figure you can expect a handy driving range in excess of 860km.

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.

Even with the assistance of an electric motor in the transmission and a turbo on the engine, a 1.2-litre, petrol three-cylinder powering a more than 1.4-tonne five-seat car is always going to be an interesting equation.

And in practice, although the small triple’s peak torque (230Nm) is available from just 1750rpm it lacks the smoothness of larger capacity mild- and full-hybrid combinations. Especially at slower speeds, the powertrain feels relatively edgy and agitated.

Outright acceleration is fine (claimed 0-100km/h acceleration is 9.4sec) with decent mid-range pulling power for confident overtaking or decisive lane changing (a 15.6kW/51Nm boost from the motor playing its part) and the dual-clutch auto is a more polished example of what can be a fractious device. 

But engineering and tuning for maximum fuel-efficiency has an impact on driveability. For example, we noticed the air-conditioning system’s output softened at standstill, which led to some mild window fogging in stop-start traffic on a particularly humid morning. Haven’t seen that for a while. 

The strut front, torsion beam rear suspension delivers a compliant ride and responsive handling in classic Peugeot fashion. The steering in particular points accurately and provides good road feel. 

We’ve covered the intricacies of the i-Cockpit instrument and steering wheel configuration in the Design section as its shortcomings (for me, anyway) are more ergonomic than dynamic.  

The car is relatively quiet, thanks in part to sound-dampening acoustic glass and the Michelin e.Primacy tyres (205/55) which also grip persistently if you decide to slice through your favourite set of corners. Push the engine harder and it’s revvy note and exhaust rasp will start to make their presence felt. 

Regenerative braking is helpful and the physical brakes (ventilated discs and the front and solid rotors at the rear) are nice and progressive.

The front seats are firmer than the Peugeot norm but remain comfy enough and they provide enough side support to keep you well located. 

Despite the swoopy fastback design, all-around vision is surprisingly good and an overall length under 4.7m, an acceptable 11.2m turning circle, a clear reversing camera and a 360-degree camera view make parking straightforward. 

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.

ANCAP awarded the GLB range its maximum five-star safety rating in 2019.

Advanced driver-assist systems in the GLB35 extend to autonomous emergency braking (AEB) with pedestrian and cyclist detection, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver attention alert, tyre pressure monitoring, hill-descent control, hill-start assist, park assist, a reversing camera and front and rear parking sensors.

Is anything missing? Well, steering assist, adaptive cruise control, active blind-spot monitoring and front cross-traffic alert form the optional Driving Assistance Package ($1990), which definitely should be standard at this price point.

And let’s not forget the two other noticeable absentees: surround-view cameras and high-beam assist. They’re annoyingly part of the optional Vision Package ($1190), which was fitted to our test vehicle.

Nonetheless, 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.

Peugeot covers the 408 with a five-year/unlimited kilometre warranty, which is perilously close to sub-par in 2026 with an increasing number of brands at seven, eight and up to 10 years conditional. The battery warranty at eight years/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/15,000km and pre-paid servicing is offered across three-, four- or five-year plans, with the latter at $2070.

That’s a not insubstantial average of $414 per workshop visit, which Peugeot says will save you $893 compared to pay-as-you-go over the five years.

For reference, a Toyota RAV Hybrid service for any of the first five years is $260, although pricing steps up after that period.

Peugeot has a well established network of 31 dealers mainly covering major cities and key rural areas, primarily on the east coast. Currently, no presence in Tassie or the Northern Territory, while Perth and Adelaide are the only representation in WA and SA. 

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.
