Mercedes-Benz GLA-Class vs Subaru Forester

What's the difference?

With Mercedes-Benz’s vast number of SUVs, there is room for an urban luxury crossover niche, and the GLA delivers in spades.

Indeed, in 250 4Matic guise, it is that rare thing – a high-riding hatch with dynamics to shame most dedicated pocket-rockets. It really is a hoot if you find the right road, regardless of weather conditions. The Benz has towering talent.

However, even without desirable options like adaptive dampers and a full suite of driver-assist safety technology, the GLA is expensive, does not quite carry off the price tag from an interior quality point of view, and struggles to maintain the degree of comfort and refinement expected from a Mercedes – with or without the $3K necessary to score adaptive dampers.

Still, especially because of the way the GLA looks, goes, stops and steers, if you can afford it, you’ll be rewarded. There’s never been a more rounded GLA.

The MY26 Subaru Forester packs plenty of punch in terms of standard features, a roomy and functional interior and overall driveability. Sure, it’s not the most exciting vehicle to drive on- or off-road but to get stuck on that is to miss the point entirely. This is a decent all-rounder with a solid background and an AWD system that long ago set the gold standard for vehicles of this type.

In a tough mid-size SUV market segment aimed more at those intent on driving through car parks rather than adventuring through national parks, the Forester offers greater versatility than most and should not be ignored.

Looking like a mini-me GLC, today's GLA trades some of its predecessor’s edgier design elements like the slammed roof and exaggerated broad-shouldered stance for a more amorphous if elegant appearance. Even with the cliché plastic cladding around the squared-off wheel arches, it’s still a looker.

The net result is arguably the most attractive of all the MFA2 A-Class offshoots. It sits well within the Mercedes hierarchy of SUVs, bringing a swoopy coupe-like silhouette compared to the ultra-upright GLB.

Along with being 30mm wider, it’s also visibly taller than before, with a handy 213mm of ground clearance compared to just 157mm last time around. And the wheelbase has been stretched to the benefit of rear-passenger room – a bugbear of the old GLA. That's progress.

This Forester is 4655mm long (with a 2670mm wheelbase), 1830mm wide and 1730mm high.

The new generation retains more than enough of the previous Forester – blocky profile included – to remain clearly recognisable.

Traditionalists may chafe at the slicker, more citified appearance of this Forester over previous generations but the overall package is inoffensive enough to not elicit any howls of outrage from passers-by on the street.

The Forester’s interior maintains a similar cabin look and feel as before but with a 11.6-inch portrait-oriented multimedia touchscreen dominating up front, a mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastics.

Compared to before, the 2021 GLA is some 122mm taller, so ushers in a higher hip point for loftier seating – reducing that jumped-up hatch feel. Headroom improves obviously, as does rear legroom, a corollary of a 30mm wheelbase stretch (to 2729mm).

Wide apertures also make entry into and out of the German-built GLA child's play, though the solid heft of their doors is serious business at this end of the segment, very satisfyingly Teutonic and totally on-brand. This is something you won’t enjoy in a Subaru XV.

Then you s-c-r-a-p-e the underside of the front doors on the pavement literally every time you swing it to get out, and wonder whether Mercedes engineers have ever been to Australia. This fail drove us spare. Heaven help the GLAs in towns and cities with bluestone sidewalks. Maybe all that extra AMG packaging is the culprit.

Still, most of the other basics are spot-on and can’t really be faulted; cosy yet spacious for four adults – especially up front, ample vision, an excellent driving position aided by heaps of seat and steering wheel adjustability, cosseting front sports buckets that you just sink into, torrents of ventilation from those delectable turbine vents and stacks of storage. Collectively they make the GLA a welcoming, opulent place to travel in. Only the hapless fifth occupant squished between the outboard rear-seat passengers might think otherwise. But nobody buys this Benz for carting people around. That's the GLB's job.

Several years ago, Daimler poached a senior Audi designer and since then Mercedes’ dashboards have morphed into a multi-coloured multimedia diorama of touchscreen technology that threatens to completely take over the universe. Choose the right combination of colours and lighting and it's like your very own White Night on wheels. Starting with 2018’s A-Class, the striking, spangly MBUX system that underpins all this has come to be widely admired and imitated. For aesthetics anyway, with its vivid hues, panoramic displays and simple, tiled applications, it’s been a real trip.

Anyway, back to reality. From a tactility and functionality point of view, there’s still work to be done.

Access to the multimedia (including our GLA's banging optional audio system) and car settings areas is possible via a mildly fiddly finger-pad arrangement down forward in the centre console, or smaller yet much more annoying thumb sensor tabs on the wheel spokes. These are not easy to modulate on the move. Additionally, their menus can be confusing to navigate through and sometimes counterintuitive in operation. Mercedes obviously realises this as a quick-guide pamphlet is provided on old-fashioned cardboard paper. How quaint.

Eventually all areas can be mastered over time, but the functionality is complicated and may overwhelm the not-so-tech savvy. Additionally, the ‘Hey, Mercedes!’ voice control is impressive for getting MBUX to perform basic multimedia and vehicle settings-related changes, but it too-often erratic, unreliable and ultimately frustrating for more complicated commands. Perhaps elocution lessons on behalf of the operator may help.

But not as much as the profound disappointment we endure from the cheapness of some of the materials, the wincing cellophane-like sounds when pressing on some of the surfaces such as the door cards, or that emanate after a particularly bumpy section of bad roads. Sheeny reflections and hard textures in a car optioned with extras that total up to nearly $82,500 just don’t cut it.  

At least in this latest-gen GLA, the rear seat area seems much improved over the previous models, with more space, comfy and supportive seating (remember ours featured the $607 sliding function that ought to be standard) and a reclining backrest. All amenities are present, with deep pockets, fresh air from twin vent outlets, reading lights and thoughtfully placed armrests – but, again, the latter’s extendable cupholders feel brittle and cheap.

Further back, the 435-litre cargo area is sufficiently sized and practical for smaller family use (at last), aided by a 40/20/40 backrest fold and that slide-able cushion to extend capacity further. There is no spare wheel, but a tyre inflation kit is fitted in lieu.

Overall, then, better than before, with that fundamental rock-solid heft, luxurious aura and alluring premium-car aroma. The dazzling MBUX screen-related visuals, too, are endlessly entertaining to explore when the vehicle is not moving, but the GLA’s cabin is still not quite up to Mercedes’ reputation for exacting over-engineered excellence.

Or even to the standards of some mainstream alternatives.

The Forester is quite roomy for a mid-size SUV and this is the top-spec variant so there’s leather everywhere.

The interior layout is neat and tidy and lands firmly on the correct side of being practical and familiar, with all controls easy to locate and operate.

The touchscreen offers mostly simple intuitive functionality with infrequent need to cycle through numerous menus and sub-menus to access what you want.

The aforementioned mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastic are welcome here because, you know... real life.

The front seats offer ample support and the driver is able to dial-in their preferred position via power controls on the eight-way power-adjustable seat (with dual memory). The front passenger has an eight-way power-adjustable seat. Both seats are heated and ventilated.

The 60/40 split folding second-row seats aren’t too shabby either, in terms of comfort and amenities, with a fold-down arm-rest with cupholders and directional air vents etc.

Cargo volume is 496 litres (with rear seat in use) and 1174 litres (with the rear seat down, 1667 litres to ceiling.

The tailgate is powered and hands-free with a kick sensor (apparently). But I never tried that, instead opting for the tailgate-mounted button to open and close it.

The Forester AWD Touring (petrol) is priced at $50,990 MLP while its hybrid sibling is $55,990.

Standard features include an 11.6-inch multimedia touchscreen (with wireless Android Auto and Apple CarPlay), 18-inch alloy wheels, auto LED headlights, dual-zone climate, heated front seats and electric folding rear seats as well as a wireless phone charger.

Top-grade additions include a sunroof, low-profile roof rails, a digital driver display, leather-accented seats, a leather auto-shifter, ventilated front seats and a 10-speaker Harman Kardon audio system.

It also has power-adjustable front seats, sat-nav, auto-dipping and folding door mirrors and a hands-free tailgate.

Exterior paint choices include 'Crystal White Pearl', 'Ice Silver Metallic', 'Magnetite Grey Metallic', 'Crystal Black Silica', 'Crimson Red Pearl', 'Brilliant Bronze Metallic', 'Daybreak Blue Pearl', 'Sapphire Blue Pearl', 'Cashmere Gold Opal', 'Autumn Green Metallic' and 'River Rock Pearl'.

Mounted transversely, Mercedes’ M260 1991cc 2.0-litre four-cylinder petrol engine features a twin-cam, 16-valve design, a twin-scroll turbocharger and variable-valve timing, to help deliver 165kW of power at 5500rpm and 350Nm of torque at a low 1800rpm. With an impressive 97.2kW per tonne, it can hit 100km/h in 6.7 seconds, on the way to a 240km/h top speed.

All four wheels are driven by an eight-speed dual-clutch transmission (DCT), though most of the torque at lower speeds or during reduced throttle loads is delivered to the front wheels until extra traction is required out back. The gearbox is one of the very best of its type we’ve experienced – seamless, strong and largely lag-free.

The Forester has the line-up’s 2.5-litre four-cylinder naturally aspirated boxer engine (producing 136kW at 5800rpm and 247Nm at 3700rpm) matched to a constantly variable transmission (CVT), which some people detest, and some people couldn’t give a rat’s whether it’s there or not.

Also onboard is Subaru’s all-wheel drive system, driving modes (including 'Normal', 'Deep snow/Mud', and 'Snow/Dirt') and 'X-Mode' “that constantly monitors the traction available to each wheel and centralises the control of key components including the engine, transmission, drivetrain and brakes to help manage slippery conditions”, according to Subaru.

Weighing in at 1668kg (kerb), and with a bluff nose and high ground clearance also not helping, we didn’t expect great fuel economy, particularly given how hard and fast the GLA 250’s performance bandwidth is. It’s tempting to just blast your way from point A to point B.

However, at the pump we averaged 9.8 litres per 100km, which isn’t too bad at all considering the available muscle. The official figure is 7.5L/100km, for a carbon dioxide emissions rating of 170 grams per kilometre. With a 51-litre fuel tank, the theoretical range is around 680km.

Note that the GLA 250 requires 95 RON premium unleaded petrol as a minimum.

Official fuel consumption on the combined (urban/extra-urban) cycle for the Forester is 7.9L/100km and it uses 91RON 'standard' unleaded petrol at a minimum.

On this test, I recorded 8.1L/100km. But fuel consumption was as low as a dash-indicated 1.7L/100km while driving the Forester with adaptive cruise control engaged.

The Forester has a 63-litre fuel tank, so, going by our on-test fuel-use figures you could reasonably expect a driving range of almost 780km from a full tank. However, as with any vehicle, once you’ve loaded the Forester with any real-world burdens (e.g kids, dogs, camping gear, etc) you’ll soon see the fuel consumption increase.

A soaring 2.0-litre turbo engine application, this is a slick, stirring and robust performer that can also do efficiency as effortlessly as launch the GLA 250 4Matic towards the horizon. Let’s not mince our words. This is a fast and fiery mover.

Three drive modes – Eco, Comfort and Sport – provide a wide spectrum of acceleration and throttle responses, and all deliver precisely what you’d expect. Eco’s fine for pottering around town smoothly and serenely; Sport morphs into a searing and seamless speed demon; and the default Comfort sits somewhere in the middle as the best of both worlds. There really is no faulting Mercedes’ M260 masterpiece.

The DCT also happens to be one of the better dual clutch autos, avoiding the lag and clunkiness pitfalls usually associated with this sort of gearbox. It’s even comparatively smooth off the line on hills. Ours came with the optional handy set of manual-mode paddle shifters, adding a welcome level of interactivity autos tend to overlook. Too bad Mercedes persists with that fiddly column lever that is forever prone to knocking the car out of drive. Even after 15 years, it's still so annoying.

What all this means for the urban driver is strong acceleration for flitting in and out of traffic gaps, as well as incredibly instantaneous point-to-point responses for commanding manoeuvrability, thanks to ultra-eager steering and assisted by outstanding brakes.

With struts up front and a multi-link rear end as standard, the GLA 250’s chassis, too, is a transformative for what is essentially a high-riding hatchback – but only if your pockets are deep enough.

Fitted with that near-$3K AMG Exclusive Package that includes adaptive dampers, our Benz displayed a definite hot-hatch attitude that really would make it the darling of Golf GTI owners who’ve outgrown their rides but not their girl/boyracer desires. Superb handling and hunkered-down roadholding really do make this the driver’s premium compact crossover. You can pretty much point and shoot this Merc as you might a Golf R, and likewise in most weather conditions thanks to all that reassuring tenacious grip.

Plus, if you’re put off by the hard ride in Sport, the Individual mode allows the driver to engage the soft damper mode while the engine and steering retain the hardcore settings. It’s a win-win situation – as long as you can stretch to that AMG Exclusive pack. We strongly recommend it, given the balance between ultimate high-speed control and comfort.

However, while this is all good news for rural and country folk seeking hot crossover fun, back around town, poor urban road conditions can reveal a flaw in the chassis’ ability to properly smother bumps and ruts. It’s the small frequency stuff that seems to transmit through, never really settling down.

The result is a jittery ride, that may somewhat undermine the GLA’s upmarket sheen. There’s also a fair degree of road noise coming through. Perhaps sticking with the 19-inch alloys instead of those lovely 20-inch rims is the solution here.

The Forester feels comfortable and composed on sealed surfaces and offers some degree of dynamism to the driving experience – so in line with previous generations.

It feels more refined, sharper to steer and more responsive than before. There’s ample visibility to the front but a substantial B pillar obscures the driver’s vision back over their right shoulder.

The Boxer engine and CVT work well together, power and torque outputs are more than adequate in this package, and that much-maligned transmission is not intrusive if the Forester is driven with care and common sense.

However, acceleration from a full stop is sluggish.

The suspension set-up – MacPherson struts up front and double wishbones at the rear – yields a firm but not jarring sense of ride and handling.

The 1662kg Forester proved nimble to manoeuvre around the Big Smoke, the suburbs and in the bush (more about that soon) with a neat 10.8m turning circle.

All-wheel drive vehicles are capable of tackling off-road adventures in their own right but, for safety’s sake, AWD drivers should avoid anything beyond well-maintained dirt tracks in dry weather. AWD cars are designed for use on bitumen roads with some dirt or light-duty off-road use.

And so it was with our test of this Forester. On-test off-road terrain equalled firm-packed sand and gravel/dirt bush tracks in dry weather, although we did drive through one shin-deep mudhole with no trouble.

The Forester has a listed 220mm of ground clearance, the suspension held up well over a brief stint on mild corrugations and Subaru AWD proved more than up to the task when things became a little trickier, providing improved grip and traction in slippery conditions that demanded to be driven at very low speeds.

If push comes to shove, it’s capable of more than light off-roading, but the Forester’s ground clearance and off-road angles ultimately limit its off-road capabilities.

The Forester’s 'all season' tyres – Falken Ziex Z001A A/S (225/55 R18 98V) – are fine for light to moderate off-roading but anything more difficult than that and you’ll need to get a set of more aggressive all-terrain tyres. It does have a full-sized spare onboard.

It has maximum towing capacities of 750kg (unbraked trailer), 1800kg (braked) and a maximum towball download of 180kg. GVM is 2223kg; GCM is 4023kg.

Some niggles: The driver awareness system is annoyingly over-reactive.

The Forester has the maximum five-star ANCAP safety rating from testing in 2024.

It has nine airbags (dual front, dual front side, dual curtain, driver’s knee, far side and front passenger seat cushion), adaptive cruise control, emergency lane-keep and centring (with departure warnings), pre-collision braking, auto emergency steering, a 360-degree view monitor system, and a driver monitoring system which includes a ‘safe stop’ feature that – if the vehicle detects that the driver is non-responsive – will bring the vehicle to a gradual, you guessed it, safe stop.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $550 for the first year, $750 for the second year and $1250 for the third year, totalling $2550. Alternatively, buyers can also choose a Service Plan, starting at $2050 for the first three years (saving $500 from the normal capped-price service plan), $2950 for four years and $3500 for five years.

The MY26 Subaru range is covered by a five-year/unlimited kilometre warranty, five-year/75,000km capped price servicing, and 12 months roadside assistance.

A service is required every 12 months or 15,000km, whichever occurs soonest. After your free “1 Month Health Check and Chat”, cost per service is $347.95 (at the 15,000km/12 month mark), $520.45 (30,000km or 24 months), $393.10 (45,000km or 36 months), $679.30 (60,000km or 48 months) and $358.20 (75,000km or 60 months). Average over the five years is $459.80.

Subaru Australia has more than 140 dealerships across the country with a decent spread over metro and regional areas. Foresters may be serviced at those dealers or by approved mechanics.
