Mercedes-Benz GLA45 vs Volkswagen Golf

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.

While some Golf enthusiasts will prefer the lighter, more nimble, front-wheel drive GTI, this Golf R is now an even more serious machine. 

It’s a great touring car, super-sharp in the corners and good value in the context of its competitive set. Cars like Toyota’s GR Corolla and Honda’s Civic Type-R are on notice.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

In terms of exterior design, at the front there’s a relatively mild cosmetic makeover with some changes to the headlights and the bumper as well as a horizontal line across the grille, which, along with the VW roundel, is illuminated.

From the side the ride height is 20mm lower, and cosmetically there are matt silver housings on the exterior mirrors, blue calipers behind new design 19-inch rims and in the centre of the wheel there’s an R logo rather than the traditional VW branding.

At the back, you’ve got new customisable LED tail-light clusters with welcome and goodbye effects, which can be programmed via the vehicle settings in the multimedia system, as well as a larger spoiler at the back of the roof on top of the tailgate.

Inside, the ‘big’ change is an appreciably larger central multimedia screen running new program software. It has physical touch bars along its lower edge for audio volume and climate control adjustment.

The driver’s display now includes a G-meter and GPS lap timing. The steering wheel has its own look and feel and the sports seats feature integrated headrests. There are alloy covers on the pedals and ‘Carbon Grey’ decorative inlays around the dash and doors.

It’s a classically restrained and subtly sporty design treatment inside and out.

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. 

For reference, the Golf R is just under 4.3m long, close to 1.8m wide and a bit less than 1.5m tall with a 2630mm wheelbase. Right in the middle of the medium hatch footprint.

In the front there’s plenty of breathing room for the driver and co-pilot. And in terms of practicality, you’ve got big bins in the doors with room for large bottles. There’s also a box between the seats with a lid that doubles as an armrest, which also adjusts for height and length, which is nice.

If you need more, there are two cupholders in the centre console, one of which is adjustable for smaller cups, plus a long oddments tray as well as a more powerful ventilated wireless device charging tray at the front end of the console.

There’s also a decent glove box and two USB-C ports for power and connectivity.

In the back, sitting behind the driver’s seat set for my 183cm position, I have ample headroom, legroom and more than enough foot room.

That said, three abreast for full-size adults would be very squeezy. Even a trio of middle teenagers might find it a bit tight. Best as a two-seater in the rear.

Then for storage, you’ve got big bins with room for bottles. Fold down the armrest and you’ve got not one, not two, but three different size cupholders in it.

There’s a nifty double pocket set-up on the front seatbacks, each just right for a phone or hand-held game console, as well as a more conventional map pocket lower down.

There are individual ventilation outlets as well as climate control for the rear section, plus two USB-C outlets.

With the 60/40 split-folding rear seat upright the 8.5 Golf R boasts 341 litres (VDA) of boot volume, which is decent, and that number expands to nearly 1197 litres with the seat down. 

There’s a load-through hatch, tie-down anchors, a 12-volt outlet, multiple bag hooks, specific lighting and storage compartments to the side.

No spare of any description, however, with a repair/inflator kit your only option.

The new Golf R is priced at $70,990, before on-road costs, which is a $500 bump from the version it supersedes. A new limited run Black Edition model, the details of which we’ll get to shortly, weighs in at $72,490.

At that money the Golf R lines up against a diverse group of properly hot hatches like the related Audi S3 ($78,800), Honda Civic Type R ($74,100), Lexus LBX Morizo RR ($76,490), Mini JCW ($56,990) and the Toyota GR Corolla ($70,490). Even higher-priced outliers like the BMW M135 xDrive ($83,600) and Mercedes-AMG A35 4Matic ($87,900).

So, the heat is on, and at 70-odd kay it’s fair to expect a decent basket of standard fruit. Aside from the performance and safety tech covered later the Golf R features list includes auto LED matrix headlights, LED tail-lights, Nappa leather-appointed trim, a leather-trimmed steering wheel, heated and ventilated front seats, three-zone climate control, 14-way electric driver’s seat (with memory), 480W nine-speaker Harman Kardon audio (including digital radio), a 12.9-inch multimedia screen (with built-in nav) and a 10.2-inch digital instrument display.

There’s also keyless entry and start, 30-colour ambient lighting, adaptive cruise, a head-up display, wireless Android Auto and Apple CarPlay, auto rain-sensing wipers, surround lighting, a (more powerful) ventilated wireless charging pad, a 360-degree overhead view, ‘Park Assist Plus’, metallic paint, fog lights and 19-inch alloy rims.

Not bad at all in the context of this category.

VW Australia has also announced an optional ‘Warmenau Package’ for the standard R - named after the location of the R division’s headquarters in Wolfsburg - for $6500 bundling up 19-inch forged alloy wheels (developed in-house by Volkswagen R, reducing the weight of each wheel by 8.0kg or 20 per cent), carbon interior trim elements and an ‘R-Performance’ titanium exhaust system from Akrapovič.

Limited to 300 examples, the Black Edition features dark accents throughout, including the wheels, badges, mirror housings, brake calipers and tailpipes, as well as darkened headlights and the lighter 19-inch forged alloys. It’s available in all three Golf R colours - ‘Pure White’, ‘Grenadill Black’ and ’Lapiz Blue’.

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.

This updated Golf R is powered by a 2.0-litre, four-cylinder turbo-petrol engine VW enthusiasts around the world know by its ‘EA888’ code name.

In this guise it now produces close to 245kW (+10kW) and 420Nm (+20Nm) with the maximum available across a broad plateau from 2100 to 5500rpm.

The 2.0L EA888 features a cast iron block and alloy head, with direct-injection, water-cooled exhaust gas routing to the turbo (in the cylinder head) and variable valve timing with double camshaft control.

Power goes to all four wheels via a seven-speed dual-clutch auto transmission and an all-wheel-drive system using a twin-clutch pack to manage front-to-rear drive distribution as well as torque across the rear axle.

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.

VW is proud to point out that thanks to an electronic coolant regulator unit, the Golf R’s 2.0L engine “features very efficient thermal management with a short warm-up phase” which it says reduces friction losses for better fuel consumption.

Its official combined cycle (urban/extra-urban) fuel economy figure is 8.3L/100km, which isn’t out of order for a hot rod hatch with this much performance potential.

Over the course of a 200km-plus road drive on the launch program, covering mainly twisting B-road and highway sections, we saw a dash-indicated average of 9.9L/100km.

With a 55-litre tank those figures translate to a theoretical range of around 660km, and a real-world number closer to 550km between fills.

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.

The Golf R weighs in at 1517kg and Volkswagen says it will accelerate from 0-100km/h in 4.6sec, which is quick, and the car’s broad torque band makes it super-usable. The maximum 420Nm is available from 2100rpm all the way to 5500rpm. 

A blue ‘R’ button on the steering wheel is your short-cut access point to various modes - ‘Eco’, ‘Comfort’, ‘Sport’, ‘Sport+’ and ‘Race’ - and in the racier settings what VW calls ‘Turbo Pre-load’ steps in. More or less an anti-lag set-up for smoother power delivery.

Even from low revs in a (manually-selected) high gear, squeeze the throttle and it quickly builds up a head of steam. Power delivery is impressively linear.

The transmission is super slick and manual shifts are rapid. Refreshingly, manual mode is exactly what it says on the tin. Select a gear with the wheel-mounted paddles and it will stay in that ratio until the rev limiter makes its stuttering presence felt.

And if you’re going into a corner under brakes just keep the left-hand paddle pulled in and the transmission will automatically cycle down to the lowest ratio available, which is handy if you’ve really got the bit between your teeth.

Even with the standard exhaust, once you’ve dialled up the sporty modes, you get that snap, crackle and pop on full-bore upshifts and on the over-run, which also enhances the experience.

Suspension is by struts at the front and multi-links at the rear, and the ‘Adaptive Chassis Control’ system monitors acceleration, braking and steering to fine-tune the set-up.

We drove on some rough B-road sections, in the wet, and the R remained surprisingly refined. Given how hard it grips and how much it communicates back through the seat of the pants it is a comfortable touring car. It’s like a GT in hatch form, eating up the kilometres without fuss or putting too much stress on the driver.

Worth noting we spent much of our time in ‘Nürburgring’ mode, accessed through the Race menu, which, no surprise, was developed on the famous Nordschleife. It’s tuned to optimise dynamic performance on undulating patchy surfaces and is a superb set-up sweet spot for the road and track.

Progressive ratio steering delivers good road feel without too many jitters coming up to your hands. And turn-in is precise without being jagged. Just point the car and it goes exactly where you want it to.

The drive system splits torque between the front and rear axles and across the rear. If, for example, it senses the car wants to turn more but might push into understeer, it calmly manages drive distribution to keep everything under control.

Tyres are Bridgestone Potenza S005 (235/35) and over even coarse chip surfaces they remain quiet and grip with admirable determination.

Braking is by ventilated discs all around and on twisting backroads we occasionally leant on them hard and they were well up to the task. A firm pedal with progressive application when getting on or easing off the brakes. 

They even stood up to a race circuit pressure test without raising a sweat, because day two of the launch included a track session at Sydney Motorsport Park. And we can confirm the car is properly fast, balanced and predictable in that environment. 

SMP’s dipping, then uphill, off-camber right-hand turn four highlighted the R’s grip and the sophistication of its torque vectoring set-up. We also went sliding on the skid pan in the car’s Drift mode, which biases the rear axle, and is huge fun.  

In terms of lower speed manoeuvring, you’ve got a 12-metre turning circle, which isn’t vast but isn’t tiny, so be ready for that.  

You’ve also got a 360-degree overhead view, which is very handy in tight spots. And if you want some extra support, ‘Park Assist Plus’ will help you slot the car into the space you’re aiming for.

Under the heading of miscellaneous observations, the sports front seats deliver solid lateral support yet remain comfortable over long periods behind the wheel.

Speaking of the wheel, it’s just the right thickness, with perforated leather at the quarter-to-three positions helping with that lovely connection to the front tyres.

As well, from an ergonomic point-of-view, working through the central multimedia screen and driver’s display is straight-forward, with the latter able to be configured via the steering wheel. 

The current Golf range picked up a maximum five-star ANCAP assessment in 2022 and VW’s ‘IQ Drive’ driver assistance tech package includes highway speed auto emergency braking (AEB) with cyclist and pedestrian detection as well as junction assist, adaptive cruise control (with stop and go), intersection assist auto-braking, low-speed manoeuvre braking, lane keeping assist, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring,  

The airbag count runs to nine - dual front, front and rear side, side curtain and a front centre bag. Then multi-collision brake minimises the chances of subsequent impacts after an initial crash. And as the name implies ‘Emergency Assist’ will take control to slow the car if the driver becomes unresponsive.

There are three top tethers for child seats across the second row, with ISOFIX anchors on the two outer positions. 

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.

The Golf R is covered by Volkswagen Australia’s five-year/unlimited km warranty, which is a match for most mainstream brands, although an increasing number are nudging up to seven and even 10 years.

There’s also a 12-year corrosion perforation warranty, which is a plus, and the recommended maintenance interval is 12 months/15,000km with ‘Assured Service’ pricing averaging $840 per workshop visit over the first five years.

Three- or five-year pre-paid ‘Care Plans’ reduce that number, with the latter working out to an average of $658 per service. Far from over the top for a performance hatch like this one.
