Mercedes-Benz A45 vs Volkswagen Golf

What's the difference?

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.

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.

When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.

That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.

But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.

Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.

Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.

The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.

The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.

The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.

And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.

Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.

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.

Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.

The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.

Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.

Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.   

Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.

I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).

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’.

There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.

It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.

The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.

What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.

Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.

Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.

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.

Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.

My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.

That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.

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.

I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.

And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.

So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.

The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.

And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.

The performance and dynamics, however, felt as sharp as ever.

Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.

Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.

So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.

The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.

A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.

As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.

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. 

The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.

Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.

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.
