Mercedes-Benz GLA45 vs Ford Transit Custom

What's the difference?

A performance SUV should be an oxymoron and is no doubt a niche product. Is it a high-riding hot hatch? Or a mega-potent small SUV?

Turns out the Mercedes-AMG GLA 45 S is a bit of both and delivers the thrills of a performance car without any of the packaging or comfort-related issues.

While it is getting a little expensive at over $100,000, its blend of space and pace is hard to beat.

The Ford Transit Custom Trail has plenty of appeal as a work van or a camper fit-out candidate. It’s a well-packaged, comfortable and contemporary van that’s nice to drive and as a bonus, with all-wheel drive it’s given the scope of capability to be able to tackle mild off-roading situations with confidence.

It’s built for work and play and though it’s limited to two-up for travels, the Trail offers so much potential as a camper conversion for adventure seekers its few niggles are easily forgotten when you’re busy making memories.

The most obvious tell that the GLA 45 S is something a little special is the Panamericana front grille, an ode to the 1952 Mercedes 300 SL, which is found on all of the German brand's hot models.

But if that wasn’t enough to give it away, the reworked bumper with larger intakes, red-painted brake calipers, lower ride height, black exterior trim and 20-inch wheels should help.

Coming round to the rear, if the AMG and GLA 45 S badges aren’t enough to give away this car’s sporting intent, the quad-exhaust tips and diffuser are sure to give any tailgaters pause.

Our car also came with the optional 'Aerodynamics Package', which adds front fender flicks and a massive roof-mounted rear wing for an even racier look.

If you think the GLA 45 S looks a bit like a jacked up hot hatch, you aren’t far off. Overall, we reckon Mercedes has done a great job at translating the aggressiveness of its A 45 hatch to the larger, higher-riding GLA.

Without the aero package optioned, you might even call it a bit of a sleeper, and it’s certainly more subdued in styling compared to its Audi RS Q3 rival.

In fact, the GLA 45 S might be too subtle for such a hot SUV, at least for our tastes.

Whereas the A 45 S and CLA 45 S get bulky fenders and a hunkered-down, aggressive stance, the GLA 45 S could just blend into the sea of SUVs seen out on the streets, especially without the aerodynamics package added.

Your mileage will vary though, and for some, the subtler looks will be a positive.

Anyone who has sat in a recent small Mercedes should feel right at home in the GLA 45 S, and that’s because it shares much of its interior design with the A-Class, CLA and GLB.

As mentioned before, the 10.25-inch centre screen takes care of multimedia duties, but there are also clicky and tactile buttons underneath for climate controls.

Key to the interior design though is an all-digital instrument display, which is laid out on the high-definition 10.25-inch screen.

With two screens facing you, you might think it’s a bit of information overload, but you can tweak each display to show the information you want.

The digital instrumentation might not be as intuitive as Audi’s 'Virtual Cockpit', but the layout and design of the interior is easy to use and offers owners plenty of customisation to get it right.

It looks like a van but with some striking yet low-key flourishes that all kind of work as a whole. Those include a Trail grille and the matt black alloy wheels. The yellow sticker-pack is a neat touch.

The Trail has more presence than a regular Trend with its 30mm-taller raised suspension and overall adventure-ready look with strong front end and chunky wheel arches.

The striking but low-key theme continues inside with a neatly laid-out yet spartan cabin. The two synthetic leather seats are topped with Trail embossing and lined with yellow stitching.

The cabin is separated from the rear cargo area by a bulkhead, which incorporates a small wired window.

The new-generation GLA 45 S has grown in all dimensions compared with its predecessor, making it much roomier and more practical than before.

For reference, it measures 4438mm long, 1849mm wide, 1581mm tall and features a 2729mm wheelbase, but still sports a roomy cabin for four adults, especially in the front seats.

Storage options include decent door pockets that will accommodate large bottles, a deep centre storage bin, smartphone cradle that doubles as a wireless charger, and two cupholders.

Being a small SUV, the rear seats also afford plenty of room for occupants, with more than enough space for head, shoulders and legs – even with the front seat adjusted to my 183 cm (6'0") frame.

There are decent door pockets, air vents, and USB-C ports that should keep passengers happy on long trips, but the GLA 45 S doesn’t have a fold-down armrest or cupholders for the rear seats.

The boot, however, is where the GLA 45 S really starts to make a case for itself compared to the A 45 S.

The boot boasts 435 litres of volume, and can expand to a massive 1430L with the rear seats folded – making it about 15 per cent bigger than the A 45 S – while the higher load height should make loading and unloading groceries a bit easier. 

A downside of the GLA’s tech-focused interior, though, is that all the USB ports are now USB Type-C, meaning you’ll likely have to carry around an adapter to use your old cables.

Mercedes is generous enough to include one with the car, but given most device chargers are still USB Type-A, it is something to be aware of. 

It’s a van so there are two distinct sections to the Trail, the cabin and the load space.

Firstly, the cabin. More a work-friendly than family-friendly interior, this Trail is a two-seater with plenty of durable plastic everywhere – ready for work and life – as well as charging (with USB-A and -C ports) and storage (including a van-favourite dash-top slot for logbooks etc, outboard moulded cupholders and a nifty pop-out cupholder), all amenities enough to cope with most daily van-related duties.

The seats are comfortable, supportive and have a fold-down lock-in-place armrest.

Now for the load space. There are no seats back there and as such it has plenty of potential as a work van or touring vehicle.

Access to the rear load space is via a barn door at the back and this Trail has a sliding door on both sides.

The cargo area is substantial – 3002mm long (to the bulkhead; 3450mm long if load-through hatch is used), 1392mm wide (between wheel arches) and 1425mm high (floor to roof). Easily big enough for work equipment or recreational gear. It can cope with four Euro pallets (each measuring 1200mm x 800mm) and it has a listed maximum load volume (with the bulkhead) of 6.8 cubic metres.

Load height through the rear barn doors is 531-585mm, depending on how much weight is already onboard.

The load space has the aforementioned metal bulkhead (with window and load-through hatch), load area protection kit (full height walls and moulded floor), LED lights and eight tie-down loops.

Otherwise, this is a load area ripe for customisation. Maybe a plethora of shelves for a tradie, or some bedding and extra storage for an adventurous person or couple.

The 2025.75Y Ford Transit Custom Trail has a MSRP of $61,990 (excluding on-road costs).

Standard features onboard include a 13-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a 12-inch digital instrument display and synthetic leather upholstery with Trail logos on the seats.

Other gear includes an eight-way manually adjustable driver’s seat, keyless entry and start, front and rear parking sensors, climate-control air and automatic LED headlights.

It also has all-wheel drive, LED headlights and daytime running lights, a variant-specific grille, black wheel arch moulding and side strip, yellow exterior decals and 16-inch matt black Trail twin-spoke alloy wheels.

The standard no-cost exterior paint is 'Frozen White'. Anything else – 'Agate Black Metallic', 'Grey Matter', 'Magnetic' or 'Moondust Silver' – will cost you $700.

Powering the Mercedes-AMG GLA 45 S is a 2.0-litre turbocharged petrol engine, outputting a staggering 310kW/500Nm.

This means the new car jumps up 30kW/25Nm compared to its predecessor, explaining (at least in part) the price jump.

The GLA 45 S is also the top-spec version globally. The 285kW/480Nm GLA 45 which is available overseas would be more directly comparable to the old car.

The engine is also the most potent production 2.0-litre on earth, and is shared with the A 45 S and CLA 45 S.

Paired to the engine is an eight-speed automatic transmission, which sends drive to all four wheels via Mercedes’ '4Matic' system.

As a result, the GLA 45 S will accelerate from 0-100km/h in a frighteningly quick 4.3 seconds, and carry on to an electronically limited top speed of 265km/h.

This is 0.4s slower than its A 45 S sibling, in part due to its heftier 1807kg weight.

The Ford Transit Custom Trail has a 2.0-litre four-cylinder turbo-diesel engine producing 125kW at 3500rpm and 390Nm at 1750-2500rpm.

The Trail has a clever eight-speed automatic transmission and an on-demand all-wheel drive system.

It all works rather well, but it’s a van afterall and as such it is less dynamic and more dependably driveable than perhaps a cross-shopped SUV wagon. However, as an AWD van the Trail can be trusted to keep its grip on wet bitumen, soggy grass and loosely-gravelled tracks and that’s a strong part of its appeal over a 2WD van.

Official fuel consumption figures for the GLA 45 S are pegged at 9.6 litres per 100km thanks in part to an engine start/stop system.

We managed 11.2L/100km after a few days of testing around Melbourne’s inner city and winding country back roads, but those with lighter feet will no doubt come closer to the official figures.

A performance SUV that can ferry kids and groceries, out accelerate  nearly everything else on the road, and sip around 10L/100km? That’s a win in our book.

The Ford Transit Custom Trail has an official combined cycle (urban/extra-urban) fuel consumption figure of 8.5L/100km. On this test I recorded 8.8L/100km.

The Trail has a 70-litre fuel tank so going by my on-test fuel figure you could reasonably expect a driving range of about 795km from a full tank of diesel. However, as with any vehicle, once you’ve loaded the Trail with real-world burdens (e.g kids, dogs, camping gear, etc) you’ll soon see that fuel consumption increase.

If the bespoke styling wasn’t enough of a giveaway, all it takes to realise you are behind the wheel of something special is to turn on the GLA 45 S.

The prodigious engine is fantastic in the A 45 S and CLA 45 S and is no different here.

With peak power coming in at a heady 6750rpm and maximum torque available from 5000-5250rpm, the GLA 45 S likes to rev and makes it feel a little like a naturally aspirated engine in character.

Don’t get us wrong, once the boost becomes available, you will feel that shove into the back, but it’s great that Mercedes has made the engine perform a little more predictably.

Paired to the engine is a smooth shifting eight-speed dual-clutch automatic transmission, which is one of the better versions I've experienced.

Many DCT bugbears, such as jerkiness at low speeds and clunkiness when putting into reverse, aren’t apparent here, and the transmission is up to the task when puttering around town or when driving spiritedly.

Speaking of which, the GLA 45 S’ different drive modes will easily change its character from tame to wild, with available options including ‘Comfort’, ‘Sport’, ‘Sport+’, ‘Individual’ and ‘Slippery.’

Each mode will tweak the engine response, transmission speed, suspension setting, traction control and exhaust, while each can also be mixed and matched in the ‘Individual’ drive mode.

However, a missing feature for the GLA 45 S that is found in its A 45 S and CLA 45 S siblings is a drift mode.

Sure, how many small SUV owners are going to take their car to a track to make use of it, but it still would have been nice to have the option.

With three levels of suspension setting, though, the GLA 45 S offers enough variability to be comfortable around town and soak up the bumps thanks to its long suspension travel, while also switchable for a more involved, driver-focused feel.

The GLA 45 S might never corner as hard or fast as its A45 S sibling, but being an SUV brings its own unique set of plus points.

It’s easy to get in and out of the Trail’s driver seat with a wide-opening door and a big step to help you inside.

The seats are comfortable and it’s simple enough to dial-in your driving position via the tilt-and-reach adjustable steering wheel and manually-adjustable seat.

Word of warning: the auto transmission is operated via a stalk mounted on the right-hand side of the steering wheel column, which takes some getting used to.

Once underway, the Trail is punchy enough around town and in the suburbs with its 2.0L 'EcoBlue' turbo-diesel engine offering a more-than-adequate amount of power and torque (125kW and 390Nm) and its clever auto helping out with nifty moves through traffic (for a van, anyway).

Visibility is impressive from the cabin and you’re afforded a convenient vantage point with the Trail standing a bit taller than its regular Transit Custom stablemates as it’s on lifted suspension, but feeling composed on most surfaces.

The Trail has a listed kerb weight of 2046kg and a turning circle of 12.1m, pretty standard for a long wheelbase van, so this is not an insubstantial vehicle and it’s a bit tricky to 'flip a u-ee' if the situation demands it.

It has six drive modes – 'Normal', 'Eco', 'Slippery', 'Tow/Haul', 'Sport', 'Trail' – which each adjust engine torque, throttle response and traction control, among other things, to suit the road surface and conditions.

But we’re all here to see how it goes off-road, aren’t we?

Well, obviously this is no rock-crawling machine and it’s not intended to be. It’s best thought of as having an all-wheel drive system that gives this van mild off-road capabilities, as in it can tackle wet bitumen, soggy grass, lightly corrugated bush tracks and very shallow mud puddles with more confidence than the Transit Custom Trend it's based on.

In a nutshell, the AWD Trail will be able to handle most low-level traction-compromised scenarios. But it does not have enough ground clearance, wheel articulation, grip or underbody protection to tackle any terrain beyond modest off-roading.

Speaking of grip, the Trail as standard rides on Bridgestone Duravis R660 (215/65 R16) rubber, a van/light truck commercial tyre and they are not so well suited to dirt tracks and the like. Grippier all-terrain tyres would help this van perform slightly better off-road than on its showroom rubber.

In its favour, the Trail has a front skid plate and underbody protection in case it cops some knock from the ground during its adventures.

Not in its favour, however, especially as a potential touring vehicle, is the fact it has a space-saver spare wheel and tyre.

If you’re thinking of using your Trail as a tourer, it’s worth knowing payload is listed as 1179kg, maximum braked trailer towing capacity is 2500kg, Gross Vehicle Mass (GVM) is 3225kg and GCM is 5725kg.

The Ford Transit Custom was tested as part of ANCAP’s Commercial Van Safety Comparison in 2024 and received a Platinum score “achieving a near-perfect score in safety assessments”, according to ANCAP.

The Trail has all of the Custom’s driver-assist tech and safety features, including six airbags (driver, front passenger, front side curtain and front side seat), as well as AEB, adaptive cruise control (with stop and go), traffic sign recognition and lane centering, blind-spot monitoring and assist, rear cross-traffic alert, forward collision warning, hill launch assist, side wind stabilisation, front and rear parking sensors, a rear view camera (with 180-degree split view) and on-board tyre pressure monitoring.

Like all new Mercedes-Benz models, the GLA 45 S comes with a five-year/unlimited kilometre warranty with five years of roadside assist – the benchmark in the premium car space.

Service intervals are every 12 months or 20,000km, whichever occurs first, and the first five services are available to purchase for $4300.

This actually makes the new GLA 45 S cheaper to maintain over its first five years than the outgoing car, which costs $4950 over the same time period.

Ford’s five-year/unlimited kilometre warranty applies to the Trail.

Servicing is set down for every 12 months or 30,000km and capped-price servicing is offered. Four scheduled services will set you back $2000 (including a brake fluid change at year three) which isn't over the top for a vehicle of this type.

Ford Australia has about 195 independent Ford dealers in Australia, with many located in metropolitan or suburban areas.
