Subaru Forester vs Mercedes-Benz GLA-Class

What's the difference?

To many people, this review won’t matter. There’s a large part of Subaru’s customer base that come back knowing they’ll get a practical, capable car regardless of refinement - something the brand’s rivals can’t quite match.

But even those people will be pleased to find the new Forester is a huge step-up over the last one in many areas. Sure, it’s a little late for Subaru to be joining the hybrid game in 2025, but it’s not the only brand from Japan that’s been slow on that front, and the brand’s philosophy hasn’t always been focused on efficiency anyway.

In a vacuum, the new Forester is a great adventure companion, but anyone considering a mid-size family SUV and not requiring the AWD and clearance the Forester has on offer could do better elsewhere.

For anyone else, there’s still only one option that really ticks all the boxes - and now it’s much better than before.

Just get the petrol if you’re going anywhere that could damage a tyre.

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 new Forester is a slight departure from the characterful previous generation, and to this writer’s eye that’s to its detriment. It’s not unpleasant to look at, but it doesn’t look so much like a Forester anymore.

I wouldn’t be the first to say it looks like it had at least one pass through the North American Ford design centre, but even putting that aside, the rounded front is a less interesting design treatment than we’re used to seeing from Subaru.

Its side profile shows off its boxy, practical nature, however, and from the rear it looks much more Subaru-like than from the front.

In Sport guise, particularly, the Forester’s bronze trim and wheels are a decent give-away that the brand was going for a more premium look.

Inside, the Forester doesn’t look enormously different from the last generation, especially when it comes to buttons, shifters, and the big vertical 11.6-inch touchscreen, the latter right out of other Subaru models that have been around a while.

But perhaps that was deliberate, because some of the new Forester’s best features are those that follow the notion of ‘if it ain’t broke, don’t fix it’.

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.

Perhaps the best selling point for the new Forester is that it hasn’t changed a whole lot inside. It’s spacious for its class and has physical buttons for a lot of things, while making sure the key controls like climate are always accessible on the touchscreen without needing to navigate through menus.

The steering wheel and gearshift look familiar and the general layout of the Forester seems to follow the brand’s established pattern of convenience over anything that could be annoying or complicated.

The software on the big screen is the same as any recent Subaru SUV with big buttons and a simple menu structure that means you rarely get lost. It’s not cutting-edge, but it works, much like a lot of the elements of this car.

The seats are comfortable and the seating position and steering wheel adjustment work well regardless of grade.

One element of the interior that works particularly well is visibility. Subaru made the headrest a little narrower to assist with shoulder checks and make looking over to the back seat easier. The result is a clear view, not only of the interior but also through those annoying side angles your wing mirrors might miss.

The back seat is also plenty spacious, with ample knee, foot and hip room in the second row’s outboard seats. Head and shoulder space is also fab. There’s little risk of feeling cramped in the back, even for a proper adult, especially if there’s a sunroof for that extra light.

Behind the second row, there’s 496 litres of boot space in non-hybrids, and 484L in hybrid variants, plus a switch in the boot to drop the second row from the tailgate.

That allows for 1174L and 1162L in petrol and hybrid models, respectively, though a big downside for the hybrid models is the lack of spare wheel, just a repair kit.

No spare tyre in a car you expect to be able to take off-road isn’t good enough, and it’s the key reason the Forester doesn’t score a full 10 for interior practicality. A shame, because the rest of the cabin is built for ease.

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 latest GLA’s evolved dimensions is presumably to put some space between it and its GLB 5+2-seater SUV fraternal twin, giving Mercedes-Benz blanket SUV market coverage. From GL (for Geländewagen, or off-road vehicle) A, B, C, E and S (as well as the G-wagen icon that started it all back in '79), there’s a premium option for everybody… if not every budget.  

In the GLA’s case, the entry-level 200 front-driver starts from $55,100 (before on-road costs); moving up to the $66,500 250 4Matic, and then to two performance powerhouses – the AMG 35 4Matic and supernaturally fast AMG 45 S 4Matic+ flagship, from $82,935 and $107,035 respectively.

Even the base GLA 200 includes new and improved autonomous emergency braking (AEB) among other safety-related technologies, as well as the brand’s glamorous MBUX multimedia system with wireless Apple CarPlay/Android Auto, digital radio, satellite navigation, reverse camera, climate control, wireless phone charging, powered tailgate, automatic parking, auto high beam, rain-sensing wipers and 19-inch alloys.

All the extra techy stuff doesn’t come for free though – prices jump almost $10,000 over the less-powerful previous-generation GLA 180 that the 200 replaces – though we expect the former badge to return in time.

In contrast, the GLA 250 4Matic is ‘only’ $3500 more expensive than its predecessor, gaining a terrific 2.0-litre four-cylinder turbo instead of a Renault-Nissan-sourced 1.3-litre turbo, all-wheel drive (with an Off-Road Engineering Package that gives the car some very light off-road capability), and other niceties such as heated electric front seats with memory function, a panoramic sunroof, more direct steering and lowered suspension (for a sportier drive).

Note that adaptive cruise control costs extra – a curious oversight at this price point. It’s part of a $1531 optional Driving Assistance Package, which also includes Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams (meaning full stop/go capability) and route-based speed adaptation. Do it.

Our test car had it, along with a $915 Vision Package (includes fancier adaptive headlights and a 360-degree camera), $1915 Sports Package (with AMG styling upgrades inside and out, perforated disc brakes, privacy glass, shift paddles and lowered ‘Comfort Suspension’), a Night Package (less brightwork, more black finishes) and sports direct-steering with corresponding wheel), $1531 20-inch AMG Black alloys, a $1915 Communications Package with upgraded audio and head-up display among a litany of other gear, $2838 AMG Exclusive Package with adaptive dampers, cooled as well as heated front seats, an ‘Energising Comfort’ ambience-enhancing 'experience' and special leather upholstery, $1531 Patagonia Red metallic paint and $607 rear-seat fore/aft adjustment. Total cost after the added luxury car tax: $82,446. Gulp.

Not cheap in anybody’s language. Nor, for that matter, are the GLA’s rivals, which owe their existence to the original’s spectacular sales trajectory and the trail that this blazed last decade.

Lexus’ loaded UX 250h hybrid AWD and Audi Q3 Sportback 40TFSI quattro slip slightly below the standard GLA 250 for both pricing and power, while the BMW X2 M35i and its Mini Countryman JCW cousin, along with Jaguar’s E-Pace E250, also offer in-the-same ballpark pricing but quite a bit more space as well as pace.

It’s also worth noting that Volvo’s XC40 T5 AWD conspicuously undercuts all from just $57,000, though now we’re talking about putting square pegs into round holes. Speaking of which…

Both Forester drivetrains use the brand’s existing all-wheel drive tech and a continuously-variable transmission, but the hybrid does something Subaru is keen to point out its rivals’ don’t.

The petrol version is powered by a (136kW/247Nm) 2.5-litre naturally aspirated flat-four ‘boxer’ engine that's largely unchanged.

The hybrid consists of the same type of engine with different valve controls and lower outputs of 121kW/212Nm. 

The key part is it’s assisted by a 90kW electric motor that, rather than being mounted to the rear axle and engaging when traction is needed, is placed before the transmission and sends electric power to all four wheels. Total outputs for the Hybrid variants are 145kW and 276Nm.

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.

Subaru claims the Forester drinks 7.9L of petrol (minimum 91 RON) per 100km or 6.2L/100km in hybrid guise.

The latter's a bit of a let-down given Toyota’s RAV4 hybrid in AWD guise comes with a 4.8L/100km claim and that system's been around for ages.

Both Foresters have a 63-litre fuel tank, so could theoretically travel a maximum 797km (petrol) or 1016km (hybrid). 

Don’t expect to manage that in real-world driving, though. The trip computer reading for the last car I drove on test (a hybrid) was 7.8L/100km after a mix of highway and off-road running.

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.

On paper, the new Forester hasn’t changed to a great degree. With that engine and the late-ish introduction of a proper hybrid system, you might expect the Forester to be undercooked. 

Sure, Subaru is playing catch-up and it would be a fair to say adding a hybrid grade to its mid-size SUV in 2025 puts it behind the curve, but Subaru is leaning into its niche.

Subaru’s very happy about being able to claim the Forester is the only hybrid mid-size SUV on sale where the one hybrid motor drives all four wheels mechanically thanks to its 'symmetrical' all-wheel drive system. Then there’s the "class-leading" 220mm of ground clearance.

But as well as being capable off the road, the Forester needs to be a decent day-to-day companion. Fortunately, it’s both.

The new Forester’s road manners are a surprising step-up over the previous generation’s, which felt soft and agricultural at times.

Subaru touted the new car's incremental improvements, but behind the wheel it feels like they add up to a far superior experience. The Forester is still a little noisy - mainly wind and road noise - but many of the elements that were once a let-down are much more refined.

The CVT doesn't complain so much when called upon to pick up the pace, and the steering feels much sharper. The former could be down to a huge increase in sound-shielding, the latter likely due to Subaru’s use of the dual-pinion steering system borrowed from the WRX.

Subaru says it “reduces mechanical resistance and eliminates unwanted feedback from the motor”. It seems to have done exactly that.

Perhaps most noticeable is the suspension, which feels more tied-down and stable than before, without sharpening up too much and becoming uncomfortable. Subaru says revised spring rates, better under-body aero and a more rigid chassis all contribute.

The hybrid and petrol have different suspension set-ups, the latter feeling softer in terms of damper response but still far more confidence-inspiring than the previous-gen Forester.

It all comes together to create a driving experience that’s easy and comfortable at traffic speeds and fun and engaging at high speeds on, for example, the smooth winding back-roads of New Zealand’s South Island.

The problem for Subaru is that despite having introduced a new hybrid system, the petrol-only Forester is just as good from behind the wheel. The advantages the hybrid brings in terms of efficiency will be a draw for some, but in terms of driving dynamics the extra power and torque on offer is probably not worth the extra outlay.

Then there’s the lack of a spare wheel… which should be a requirement when you’re off sealed roads. The gravel and mud of the Canterbury region didn’t faze the Forester, though, and we put the mid-size SUV through its paces harder than most owners realistically would.

Deep mud ruts, creek crossings and jagged rocky trails were all traversed easily and comfortably, especially considering the standard road tyres fitted. 

None of the test cars were stuck due to either negligent road testers or lack of mechanical ability on the Subaru’s part, though two cars on test did succumb to an excess of water in the engine bay and went into a safety shut-down mode once we arrived back at the end of the off-road trail.

We asked Subaru for an explanation and we were told it’s a feature that saves components like the cooling fan from water damage.

“Two vehicles experienced this due to the nose being submerged from entering the water crossing at the incorrect speed and/or entry line… if water enters the engine bay at a sufficient level, a protective fuse is designed to engage to safeguard the radiator fan motor.

“This system functioned exactly as designed. Despite this, the vehicle continued to perform as intended, enabling the driver to complete the off-road course and return safely to the Homestead. 

“After cycling the ignition, a warning light alerted the driver, and the engine shut down automatically to prevent any potential damage. This sequence is outlined in the Owner’s Manual. This is a built-in protection protocol and not a fault.”

A replacement fuse meant one of the vehicles “resumed full operation,” a Subaru spokesperson added.

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.

Mercedes-Benz is a long and proud pioneer in passenger-vehicle safety, and the GLA is no exception… except that for the full suite of safety assistance you need to fork out more in the GLA 250.

The standard roll-call of advanced driving assist systems includes nine airbags (front, pelvis side and window bags for driver and front passenger, side airbags for rear occupants and a knee airbag for the driver), AEB with pedestrian and cyclist detection, and blind-spot monitoring with an exit warning that alerts the driver of approaching cyclists or vehicles if the door begins to open into their path.

The AEB system has a working range of between 7km/h and 200km/h.

Active Lane Keep Assist, an active bonnet that raises to reduce head injury, Cross Wind Assist, Pre-Safe accident anticipatory systems and traffic sign recognition tech are also present.

Additionally, front and second-row seatbelt reminders are fitted, as well as two rear-seat sited ISOFIX child-seat anchorage points and a trio of child-seat tether points behind the backrest.

But you’ll need to fork out another $1531 for the optional Driving Assistance Package, which includes adaptive cruise control with full-stop/go, Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams, and route-based speed adaptation.

At the time of publishing, the H247-series GLA’s crash test rating results had not been published, but the closely-related GLB tested in 2020 managed a full five stars.

Subaru‘s five-year, unlimited kilometre warranty is behind the curve for mainstream brands with many offering between seven and 10 years, but its eight-year/160,000 kilometre hybrid high-voltage battery warranty is par for the course.

Servicing intervals are every 15,000km or 12 months, with servicing pricing locked in for the first 75,000km or 60 months of ownership. Total cost over this time is $2299 for either drivetrain, with the cheapest service being $347.95 and the most expensive $679.30 (at 60,000km or 48 months).

Subaru also offers 12-months complimentary roadside assistance.

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.
