Mercedes-Benz A45 vs Abarth 595

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.

It’s tough to be kind to the Abarth 595. Based on a platform that’s more than a decade old, the car has been left behind by its rivals in many ways, including basic ergonomics and its value equation.

The larger engine does work well in this smaller package, and its road-holding ability belies its size. However, only die-hard fans of the Abarth brand will be able to cope with the uncomfortable seating position and a complete lack of even the most perfunctory features that cars costing $10,000 less are able to offer.

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.

Despite being based on a design that’s a decade old, the Abarths still stand out. Based on the classic Fiat 500 shape of the 1950 and '60s, it’s more cute than cut-throat, with a narrow track and tall roof giving it a toy-like presence.

The Abarth attempts to beef things up with deep front and rear bumper splitters, go-fast stripes, new headlights and alternate-colour wing mirrors.

The 595 rides on 16-inch rims, while the Competizione runs 17s.

Inside, it’s definitely different to most mainstream cars, with colour-coded plastic panels on the dash and a very upright seating position, along with a dual-tone steering wheel.

It’s a love-it-or-hate-it proposition. There’s no middle ground here.

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).

This is another area where the Abarth falls down. First and foremost, the seating position for the driver in both cars is utterly compromised.

The seat itself is mounted far, far, too high, and has little adjustment in any direction, and there is no reach adjustment in the steering wheel column to allow a taller (or even an average height) driver to get comfortable.

The more expensive Competizione we tested was fitted with a set of optional sports bucket seats from racing company Sabelt, but even they are mounted literally 10cm too high. They are also ultra firm, and even though they look supportive, lack decent side bolster support.

The tiny multimedia screen is okay to use, but the buttons are miniscule, while there’s a complete lack of storage places in the front. 

There are two cupholders under the centre console, with two more in between the front seats for rear seat passengers. There are no bottle holders in the doors and no storage for rear seaters.

Speaking of the rear seats, they are the very definition of cramped, with little headroom for moderately sized adults and precious little knee or toe room. There are two sets of ISOFIX baby seat mounting points, though, should you fancy wrestling your wriggling toddlers through the narrow aperture.

The seats flip forward to reveal more cargo space (185 litres with the seats up, and 550 litres when the seats are down), but the seat backs don’t fold flat into the floor. Under the boot floor is a can of sealant and a pump, but no space saver spare.

In truth, it was a long day testing this car… at 187cm, I simply could not get comfortable in it at all.

The range has been stripped back to just two cars, and costs has come down slightly, with the 595 now starting at $26,990, plus on-road costs. 

A new 5.0-inch touchscreen multimedia system (with digital radio), a leather wrapped steering wheel, TFT dash display, rear parking sensors, alloy pedals, 16-inch alloy rims, and (front-only) adaptive dampers are standard on the base 595.

A convertible, or more accurately, a rag-top (cabriolet) version of the 595 is also available for $29,990.

The 595 Competizione is now a whopping $8010 cheaper at $31,990 with a manual gearbox, leather seats (Sabelt-branded sports buckets are optional), 17-inch alloys, a louder Monza exhaust, as well as front and rear adaptive Koni shocks, and Eibach springs.

Unfortunately, what stands out more on the Abarths is what they don’t come with. Auto lights and wipers, cruise control of any sort, driver aids including AEB and adaptive cruise… even a rear view camera is missing.

What’s more puzzling is that the Abarth’s architecture, though a decade old, has provision to accept at least a rear view camera.

Abarth’s explanation that the car’s home market doesn’t see these inclusions as important doesn’t really hold water, either.

In terms of value, the lack of basic content sends the Abarth to the bottom of a competitive pile that includes both the Ford Fiesta ST and the Volkswagen Polo GTI.

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.

The Abarth 595 pair use the same 1.4-litre 'MultiJet' four-cylinder turbo engine in differing states of tune. The base car makes 107kW/206Nm, while the Competizione makes 132kW/250Nm, thanks to a freer-flowing exhaust, a larger Garrett-branded turbocharger and an ECU re-tune.

The base car can do 0-100km/h in 7.8 seconds, while the Competizione is 1.2 seconds quicker; the optional 'Dualogic' automatic is 0.2sec slower to the mark in both cars.

A five-speed manual gearbox is standard, and neither car is fitted with a limited slip diff.

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.

Over 150km of testing, the Competizione consumed a dash-indicated 8.7 litres per 100km, against a claimed combined fuel economy figure of 6.0L/100km. Our brief test of the 595 revealed a similar number, against the same claimed figure.

The Abarth will only accept 95 octane fuel or better, and its small 35-litre tank is good for a theoretical 583km 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.

Ergonomics aside, the combination of torquey engine and lightweight car is always a good one, and the 1.4-litre turbocharged four is a good match with the front-drive Abarth.

There’s always enough mid-range urge to give the Abarth the hurry-up, and the longer-legged five-speed gearbox is a good match for the engine.

It also grips and turns surprisingly well, despite the Sport button adding too much artificial weight to the Abarth’s steering feel. 

That same button also firms up the front dampers on the 595 and all four on the Competizione, which works well on smoother terrain, but stiffens it too much over more undulating surfaces.

Around town it can be hard to strike a good balance between ride and comfort. The difference between soft and firm is much more pronounced in the Competizione, but it will still get tiring if your commute is a bumpy one. 

The turning circle, by the by, is ridiculously large for such a small car, making u-turns - already compromised by the lower front bumper - unnecessarily fraught.

The Monza exhaust on the Competizione gives it a bit more presence, but it could easily be louder (or at least more crackly) again; you’re not buying this car to be a wallflower, after all.

Despite a lack of electronic safety aids – and, somewhat amazingly in the current age, a rear-view camera – the Fiat 500 that forms the Abarth's basis still carries the maximum five-star rating from ANCAP it was awarded in 2008, by dint of its seven airbags and bodyshell strength. 

It wouldn’t have the same luck if it were judged under new ANCAP regs coming into force in 2018, though.

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.

A three-year/150,000km warranty is offered as standard on the Abarth 595 range, with a suggested service interval of 12 months or 15,000km.

Abarth importer Fiat Chrysler Automobiles Australia offers three fixed-priced services for the 595 range at 15,000, 30,000 and 45,000km, with the first costing $275.06, the second $721.03 and the third $275.06.
