Mercedes-Benz GLB vs Subaru Trailseeker

What's the difference?

The new GLB is a worthy successor to the original. It has retained everything that made it such a unique proposition but improves where it counts - interior space and comfort, in-car and safety tech, standard features, powertrain, ride quality and, importantly, value-for-money.

The EV is the pick of the powertrains and while I didn’t get to drive it, the GLB250+ is the best value.

Servicing is expensive and the standard glass roof is a bugbear but if you can cope with those things, the boxy GLB is a terrific smallish family SUV.

The Subaru Trailseeker AWD really hits it out of the park when it comes to its comfort, practicality and all-round solid family features. It's one of the nicest EVs I've sampled of late when it comes to handling and power delivery.

There's no doubt that it's a capable car being a dual-motor AWD and sporting a great ground clearance ... but it's still an EV.

And the general rule of thumb is that it's best to avoid off-roading in most EVs (potential battery damage yadda yadda), you also can’t plug it into a gumtree to charge.

Is it a comfortable family wagon-SUV crossover? Absolutely. Will you actually be driving ALL of those trails it's promising to seek out? We'll see.

The original first-generation GLB was a standout when it comes to exterior design. It was boxy, upright and unlike anything else in the premium SUV segment. If you wanted a conventional Mercedes SUV you could opt for the smaller, bubble-shaped GLA or the larger, more sophisticated GLC.

But the GLB occupied its own space. Thankfully Benz has largely stuck with the script for the second-gen GLB, but they’ve modernised it.

Built on the new Mercedes Modular Architecture (MMA), the GLB is a full 98mm longer, has a 50mm longer wheelbase, is 27mm wider and 14mm shorter. And it does look noticeably lower to the ground compared to the old model.

While the square silhouette remains, Benz’s latest design direction is seen everywhere. The front end is more rounded now and has a large gaping low-set grille with an LED light bar running the width of the bonnet. It’s an acquired taste but I prefer the previous GLB face.

The rear is a much better angle for the GLB. Looking at it directly from the rear, it has pronounced shoulders that give it a lovely muscular look, and the curved tail-lights are a highlight.

Benz is leaning into its brand in a bid to stand out in an increasingly competitive global market. It’s doing this by using the iconic three-pointed star as a motif in the head and tail-light cluster, as well as the grille which is illuminated for some grades. I’m not sold on that element as it feels a bit over the top, but at least you won’t get confused about what brand of car it is.

Another design element I’m not sold on is the pop-out door handles. With car companies finding better solutions for handles, this seems out of touch.

Inside, everything feels upright. The integrated glass dash panel spans the width of the cabin, while brushed aluminium panels also feature. The signature Benz seat adjuster switches on the doors and the gorgeous air vent design have been upgraded successfully.

The three-spoke leather steering wheel in the GLB350 is a highlight - it’s the perfect width and well executed.

Overall the design is modern, tech focussed and very Benz.

This is not a pillowy or small wagon-SUV (can we make WUV a thing?!) crossover. At 4845mm long, 1860mm wide and with 211mm of ground clearance, the Trailseeker isn’t compromising on size just to slot neatly into the EV category. This is very much an EV-styled Outback, which should delight fans looking for that familiar Subaru ruggedness and impressive on-road presence.

The biggest tell-tale sign that this is, in fact, an EV is the front end, which gets smooth panelling and a more streamlined silhouette. However, you still get plastic moulding around easy-to-hit areas.

Full LED lighting, 18-inch alloys with aerodynamic caps and familiar paintwork colours round out the handsome offering.

Head inside and the cabin is plush and well styled, with a stepped dashboard and display design creating some interesting focal points. It absolutely scores goals with its tactile functionality, too. Buttons, steering wheel stalks and door-mounted side mirror controls keep the Trailseeker feeling very car-like, which is a welcome relief in an increasingly screen-heavy EV world.

The synthetic leather upholstery on the seats, dash and doors feels nice underhand and even the slightly odd hexagonal steering wheel soon becomes charming.

The cabin feels fresh but comfortingly familiar.

The extra length and width means more cabin space which is more apparent in the rear. But there is ample space up front, especially headroom.

The centre console sits up a little too high for my liking but it means you have under console storage with two USB-C ports, and a rubber mat so your phone doesn’t slide around.

It’s got a really deep central bin, while door cavities will only hold smaller bottles. You also get a wireless charger and two cupholders.

There is only a handful of buttons - hazard lights, volume, voice command and drive mode selection - under the central air vents. All other functions are found in the multimedia screen.

Benz has been a standout in the past decade with its MBUX multimedia system and the latest version is responsive, relatively easy to navigate (once you’ve located the key controls), and the graphics look super sharp and cool. The digital instrument cluster is similarly excellent.

Hopping into the second row, the seat base is set higher than the front seats for stadium seating. The seats have some bolstering but quite a lot of lumbar support.

There’s ample space in the second row, thanks to 68mm more space from the back of the seat to the front seat and an extra 34mm of headroom compared to the old car. I have ample knee, head and legroom behind my 183cm (six-foot) tall driving position, although my head is about the same height as the top of the window frame which impedes a little.

Amenities include smallish map pockets, two USB-C ports and knee-level air vents, which is always good to see. There’s a deep but skinny bottle holder on either side and a fold-down centre armrest that sits up a bit too high but it’s wide and has two shallow cupholders and a neat little phone holder.

Each of the 40/20/40 split seats folds via a pull strap at the seat base and the good news is you can adjust the second row backrest a little. The base is also on rails so it can slide fore and aft.

That is how you lower the seats to get into the third row, which is strictly for children. Benz has made it slightly easier for littlies to get back there but it is not a space for taller humans. In fact, Benz recommends up to 171cm tall at most.

One gripe is that there is no sunshade or blind for the massive standard panoramic fixed glass roof. Benz says it is tinted and has a film to reduce UV light and heat, but I’d say a few hours driving in Australian summer will challenge that. Benz isn’t the only brand doing this, but at least you can buy an accessory blind for your Polestar or Tesla. The fact is, not everyone wants a glass roof, especially in Australia, so this feature should be an option.

The boot can swallow 145 litres with all three rows up, increasing to 480L with the third row stowed and 1605L will all seats lowered. This is all decent for a smallish seven seater but if boot space is a priority then maybe have a look at a GLC.

There’s a floor mat and cargo blind but sadly no spare wheel of any kind, just a tyre repair kit, which isn’t great.

Subaru has nailed the available space in the Trailseeker. The entire cabin is roomy where it counts and passengers will be all the happier because of it.

In the front, the heat function, side bolsters, and deep padding make the front seats feel super comfortable. You'll get very little fatigue on a big road trip which is great for a WUV (it's happening) that's being positioned for family adventuring.

The rear row has legroom for days and there is a limo-like sense of space that taller adults will praise. When I say limo-like, I mean it. You'll easily be able to fit rearward-facing child seats behind a taller adult and make use of the three top-tether anchor points in general.

All of my passengers this week, including my parents, commented on how easy it is to get in and out of the car, and that’s largely thanks to the 211mm ground clearance and wide door apertures.

Despite missing out on a glovebox, which makes the giant User's Manual essentially homeless, there are still quite a few storage options throughout the car.

Up front, there is a shallow but wide middle console with a dual-opening lid (very Lexus coded), a centre console that has dual wireless charging pads, two cupholders and a little shelf underneath for smaller items. Each door (front and back) has bin storage and a drink bottle holder.

In the rear, there is a fold-down armrest with two cupholders and a couple of map pockets. My nine-year old is particularly chuffed with the heated outboard seat function and the dual USB-C ports. A handy addition here would have been sunblinds, like the Skoda Enyaq sports.

The boot rounds out the storage with its 609L of capacity, which is more than enough for luggage and kid paraphernalia. It’s handy having a retractable cargo cover and handsfree powered tailgate, but you only get a tyre repair kit, which isn’t super practical for a car that might want to hit a gravel road or two.

You also miss out on vehicle to load (V2L) functionality, which the Trailseeker AWD Tourer gets, and that too would help weekend adventurers.

Let's talk tech.

The 14-inch media display shares the same operating system as Toyota and Lexus, which offers a straightforward layout and responsive touchscreen. Note that this car is the mechanical twin of the recently released Toyota bZ4X Touring.

Climate controls are positioned in the screen but they're easy to operate.

There is wireless Apple CarPlay and Android Auto and CarPlay connected quickly and maintained a steady connection all week for me. You get a standard six-speaker sound system but it proved to be more than enough to successfully belt out some tunes to.

All in all, the Trailseeker AWD has a straightforward and practical cabin for family use.

Subaru is offering two trim levels of the Trailseeker: the mid-spec AWD, which is what we’re reviewing, and the slightly higher-specced AWD Touring. Before on-road costs, they’re priced at $63,990 and $69,990 respectively, making our test vehicle competitive against its nearest rivals.

The Skoda Enyaq Sportline 85 starts at $66,990 MSRP, while the Tesla Model Y Premium Long Range comes in at $68,990 and the Zeekr 7X RWD starts at $57,900. That makes the Trailseeker AWD the more affordable option than two of its key rivals, while also offering something you’ll need to level up for, both grade- and price wise, with its dual-motor all-wheel-drive system.

Standard features include:

• Keyless start
• Keyless entry (front doors)
• Electric heated front seats
• Heated rear outboard seats
• Electric lumbar support (driver)
• Rain-sensing windscreen wipers
• Dusk-sensing LED headlights
• Heated/powered side mirrors
• Powered tailgate with kick-sensor
• Digital rearview mirror
• Wireless Apple CarPlay/Android Auto
• AM/FM/digital radio
• Bluetooth connectivity
• Satellite navigation
• Dual wireless phone charging
• 14-inch touchscreen multimedia display
• Dual-zone climate control with directional air vents in rear row.
• 1x 12-volt socket
• 4x USB-C ports (2 in each row)
• 3x top-tether anchor points
• Rear door child locks
• 2x ISOFIX child seat mounts
• Tyre repair kit
• Regenerative braking paddles (steering wheel mounted)

Both mild-hybrid versions of the GLB are powered by a 1.5-litre four-cylinder turbo-petrol engine with 48-volt mild-hybrid tech that includes a 1.3kWh lithium ion battery.

The front-wheel-drive GLB200 delivers 120 kilowatts of power and 250 Newton metres of torque for an 8.7-second 0-100km/h dash time.

The all-wheel drive GLB220 4Matic gets a power and torque boost to 140kW/300Nm for a 7.5-second 0-100km/h time. Both petrol grades use an eight-speed dual-clutch automatic transmission.

For the EVs, the rear-drive GLB250+ delivers 200kW/335Nm and hits 100km/h from zero in 7.4 seconds.

The GLB350 4Matic ups that to 260kW/515Nm and a 100km/h dash time of 5.5 seconds.

The Subaru Trailseeker is powered by a dual-motor all-wheel-drive set-up with a hefty 280kW of combined power.

Subaru doesn’t quote a combined torque figure, but it can sprint 0-100km/h in just 4.5 seconds, making this feel very performance coded compared to some of its single-motor rivals.

The GLB EVs uses a nickel manganese cobalt (NMC) battery with 85kW of usable energy.

Driving range and energy efficiency for the GLB250+ is a decent 570km and 15.5 kilowatt hours per 100km. The two-motor AWD GLB350 range drops slightly to 554km and uses 17.7kWh/100km

The EVs have four regenerative braking modes. After a long morning drive in the GLB350 I recorded 15.5kWh, which is solid.

The new GLB uses an 800-volt architecture supporting DC fast charging up to 320kW. Under the right conditions at a high-powered DC charging station, you can technically add up to 260km of range in 10 minutes, according to Mercedes.

AC charging capacity is available up to 22kW and there are four regenerative braking modes, as well.

When it comes to fuel economy in the mild hybrids, the GLB200 consumes 6.1 litres per 100km and the GLB220 sips 6.5L. This powertrain has the ability to use electric power to coast when cruising at highway speeds.

The Trailseeker AWD has a large 74.7kWh lithium-ion battery and a WLTP driving range of up to 533km. I got pretty close to the claimed energy consumption of 15.4kWh/100km, with my 15.7kWh average this week. Given I’ve done some serious highway trips, that’s an impressive result.

It sports a Type 2/CCS charging port which accepts up to 22kW on an AC charger and up to 150kW on a fast DC charger. I would have liked to see a higher DC charging capacity, but on a compatible fast charger, you can go from 10 to 80 per cent in around 30 minutes, which is reasonable.

I have driven the previous GLB250, which was a fun, punchy SUV. There’s no sporty second-gen variant yet, but if you’re after performance, check out the EV rather than the mild-hybrid.

I only drove the mild-hybrid briefly at the launch event so I’ll focus most of my impressions on the EV. The GLB220 4Matic is quick enough off the line, but there is some lag. Brakes are strong and the cabin is well insulted.

But for me, the EV is the clear pick.

Of the EVs I only drove the GLB350 4Matic as Benz didn’t have a 250+ available.

It’s very quick from a standing start, but not whiplash quick and that is perfectly appropriate for a family-friendly SUV. It delivers the power in a linear manner but when you put the foot down it is very responsive.

I couldn’t detect a massive difference between Comfort and Sport mode to be honest, but you get enough punch in Comfort.

The GLB is tall and top heavy so there is body roll but that’s fine for this sort of vehicle. You’ll notice the weight of this car if you push it into a tight bend at speed - it’s quite heavy and I felt a bit of lateral movement, but the traction control systems help keep the car in check. The grippy tyres help here, too.

Benz has worked hard to improve ride quality with the new-gen model and it shows. The drive route from Melbourne’s south-eastern suburbs to the Mornington Peninsula was littered with potholes, some that looked like they could cause serious damage. The GLB soaked up even some of the sharper holes like a pro. The ride at urban speeds is calm and measured.

The sound deadening measures have clearly helped as well as it is a much quieter cabin than its predecessor. All of this adds to the feeling that this GLB is a more refined, premium SUV than the old model.

I found the steering a little light and twitchy at the start of the drive but by the end of the day I noticed some heft to the feel, and it’s still direct.

The brakes in the EV are a little slower to respond than the mild-hybrid, which takes some time to get used to.

But overall, the drive experience is largely very positive.

No one will claim that the Trailseeker is underwhelming when it comes to power. It’s quick, with no bucking through the body when you have to plant it, and it’s a perfect companion on the open road.

The suspension and steering are nicely balanced to deliver a dynamic and engaging driving experience, and I’m really enjoying how stable it feels through corners.

It’s easy to choose between the four levels of regenerative braking thanks to the steering wheel-mounted paddles. But you don’t get one-pedal driving, which seems like an important omission for an EV.

The cabin is quiet around town and on the open road, and it’s easy to chat across the cabin without raising your voice.

Visibility is quite good out the front and sides from my driving position, and I like that the A-pillar has a glass insert to break up its width. And it doesn’t matter if you have a car full of gear or people, because you have a digital rear-view mirror.

Even with the regen on its strongest level, you can still ‘creep’ at lower speeds and, coupled with a really clear 360-degree camera, the Trailseeker is downright easy to park.

The Subaru Trailseeker has a maximum five-star ANCAP safety rating from testing conducted in 2025 and features eight airbags. It didn’t manage an individual assessment score in the nineties, but still performed well, scoring 89 per cent for adult occupant protection, 86 per cent for child occupant protection, 80 per cent for vulnerable road user protection and 82 per cent for its safety assist systems.

The biggest callout here is that the new Trailseeker misses out on emergency call capability, but it is good that none of its safety equipment intrudes too much on everyday driving.

Standard equipment includes:

• 2x ISOFIX child seat mounts
• 3x top-tether anchor points
• Child rear safety door locks
• Child presence alert
• Active cornering assist
• Driver attention monitor
• Driver attention alert
• 360-degree camera (including under car)
• Blind spot monitor
• Front/rear parking sensors
• Rear cross-traffic alert
• Safe exit assist
• Adaptive cruise control
• Emergency steering assist
• Lane keeping aid
• Lane departure alert
• Traffic sign recognition
• Tyre pressure monitoring
• Engine immobiliser

The GLB comes with Mercedes’ five-year, unlimited kilometre warranty, which is now the standard in the premium segment. The EV’s battery warranty lasts eight years or 160,000km, which is also pretty standard.

Services are required every year or 25,000km which is a decent interval.

Benz offers pre-paid service packages running for three, four or five years. The mild-hybrid is $3430 for three years, $4680 for four and $6300 for five years.

The EV is more affordable to service, costing $2525 for three, $3765 for four and $4440 for five years.

This is quite pricey compared to rivals. BMW’s iX3 is offered with a six-year pre-paid plan and it’s $2420. The Polestar 4 is free to service for the first five years.

The Trailseeker is offered with Subaru’s five-year/unlimited km warranty. While some of its rivals have the same term, it’s now a below-average offering for the class in general.

Servicing, however, is downright cheap, with a three-year pre-purchased plan costing just $584.29 and the five-year plan set at $984.18. Servicing intervals are also well-spaced at every 12 months or 15,000km, whichever occurs first.

It’s also fairly easy to get your Trailseeker serviced, with around 120 Subaru service centres across Australia.
