Mercedes-Benz A45 vs Mazda 2

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 Mazda's insistence that the Mazda2 is a 'first-car' could be very limited by the incomes of most teenagers or early-20s city-dwellers, the starting price being close enough to $20,000 for a dynamically enjoyable and convenient small car isn't to be scoffed at.

The new styling of the Mazda2 is well executed, and as an alternative to small SUVs (which continue to become more popular) it's a sensible option, especially considering its efficiency and ease of use.

The lower specifications in the range are probably the best in terms of value, as even the features on the higher grades aren't groundbreaking, and the Pure SP definitely exudes the most style cred.

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.

Aside from the Pure SP, the Mazda2's styling changes are subtle. Mazda's design team aimed to move the model's looks slightly away from the previous ‘premium' chrome-adorned look to a sportier and more ‘aggressive' style.

A redesigned front bumper and mesh grille, with the rear's nip and tuck being more subtle, don't need to do much to keep the hatchback looking fresh. Despite being almost a decade old, the Mazda2 looks, to some extent, like it could be a new generation.

The Pure SP in particular is a highlight, with the blocked grille evoking some ‘electrification' vibes, while the coloured-accent treatment at the front and rear of most variants is a welcome addition for something different.

The range of differing wheels is also a plus point for the Mazda2 range, with each model having its own distinct characteristics.

Inside, the Pure SP also gets a stand-out panel across the dash in a lighter colour like mint, while others get different seat trims and colour accents in places like the vent surrounds.

New colours for the range are 'Aero Grey Metallic' and 'Air Stream Blue Metallic'.

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).

The Mazda2's interior is mostly unchanged through the facelift, with the car's overall dimensions unchanged and not affecting space for its occupants.

Up front, the two seats are comfortable for adults and arm, shoulder, and head room is ample.

Storage space for drinks, phones, or small bags and wallets is sufficient, though not quite road-trip-worthy.

In the rear seats, adults will find enough space to be comfortable for short trips but might get a little restless after a while.

Headroom when sitting upright is tight for anyone around 182cm (six-feet) tall, and a lack of armrest and little storage save for the doors means loose items will be joining occupants on the seat or sitting on the floor.

The Mazda2 has a claimed 250 litres of luggage space in the boot, which is fine for a small hatchback, but short of rivals like the Toyota Yaris' 270L.

Mazda has managed to keep pricing for its entry model relatively low for the segment. In fact, the base Pure in manual form starts from $22,410, before on-roads, and the auto is only $2000 more.

That means at a time when the Toyota Yaris is starting to look more expensive than its historic ‘cheap and cheerful' image allows, Mazda is pushing the Mazda2 to be slightly more premium while keeping its price competitive.

Standard features for the range, which start in the Pure variant, include a 7.0-inch touchscreen with Apple CarPlay and Android Auto capability, plus auto headlights and windscreen wipers.

The Pure SP, which starts at $25,210, gains a different styling kit that adds a body-coloured front panel to the grille, plus a carbon-look roof in vinyl. It also gains the ‘shark-fin' roof aerial.

The Evolve, which starts from $25,910, gains LED DRLs, with the mesh grille replacing the SP's block colour panel.

Its upholstery gets red stitching, plus it's also got a couple more tech additions with Mazda's active head-up driver display, traffic sign recognition and satellite navigation.

Finally, there's the top-spec GT, from $27,610, which gains unique aero-inspired 16-inch alloy wheels, and a set of black leather-upholstered seats with synthetic suede and red trim.

A sedan is available in Pure or GT specification at the same prices and with the same features as the hatch, though you can't get a Pure sedan in manual - that's available in the hatch only.

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.

Mazda's ‘SkyActiv-G' 1.5 litre four-cylinder petrol engine is the unit used for six-speed manual and automatic models, but outputs vary slightly.

Manual cars produce 82kW and 144Nm, while autos deliver a slightly lower 81kW and 142Nm, both driving the front wheels only.

It's pretty much the same engine you used to find in an entry-grade MX-5, just with less power.

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.

Improved fuel efficiency and lower CO2 emissions come thanks to the automatic's slight drop in power and torque.

Mazda claims a 5.0L/100 km rating for the automatic Mazda2, which is down by 0.3L/100km over the previous version, but the manual's unchanged engine tune burns through the petrol at 5.4L/100km.

Filling the 44-litre tank with at least 91RON or even E10 is fine, and with its auto variant's efficiency rating means the Mazda2 technically has a theoretical range of 880km.

Comparatively the Mazda2 scores well here, the more expensive Toyota Yaris comes with a 4.8L/100km consumption claim with its CVT auto. A Suzuki Swift, with a smaller 1.2-litre engine, also has a 4.8L/100km rating.

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.

Our drive loop for the Mazda2's launch included a mix of urban, highway, and rural driving, with varying road quality and conditions.

Fortunately for the little hatchback, it handled everything well or at least at a passing mark, with only a couple of small shortcomings that are common in the segment.

The Mazda2 is a joy to drive in most circumstances, with a lively but confidence-inspiring chassis and controls that give a connected feel to the road.

At low speeds, the Mazda2's relatively low power isn't noticeable, with the gearbox getting things moving at a reasonable pace and the engine is responsive enough with the traditional gearbox helping it along.

It's worth noting that for ultimate control over the drivetrain, Mazda still offers a six-speed manual transmission in the entry-grade Pure, and it's a gem.

Smooth, sporty shifts and well thought out gear ratios mean the manual is easy to handle even in traffic, and the clutch has a forgiving bite point. The 'i-Stop' stop/start system works with the three-pedal car, too, as does cruise control.

In terms of handling and comfort, the Mazda2 is a little shaken by large bumps, though some of the rough surfaces on our test loop were particularly brutal.

Similarly, when pushed hard to conquer steep hills the 1.5-litre engine becomes a little harsh.

On twisty sections the Mazda2 (especially in manual form) provides ample fun while remaining predictable in its steering and chassis feedback, rather than feeling loose.

The updated Mazda2 is equipped with the brand's suite of 'i-Activsense' safety tech, which includes 'Smart City Brake Support' for operating forward and reverse, blind-spot monitoring and rear cross-traffic alert.

The Evolve and GT model grades are fitted with traffic sign recognition.

The GT model grade comes fitted with front parking sensors and a set of surround-view parking cameras.

The Mazda2 also features six SRS airbags to cover the driver and front passenger, side airbags, and curtain airbags front and rear. It also has ISOFIX anchor points and top tethers for child seats in the rear.

Mazda isn't going to put the Mazda2 up for a new crash test rating by ANCAP, with the brand telling us the new safety additions bring the car's safety up to date, though its original rating from 2015 was a maximum five stars.

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.

Mazda offers a five-year/unlimited-kilometre warranty across the range, under which the Mazda2 will be covered. That's on par for the market, although some rivals, like the MG3, come with a seven-year term.

Scheduled servicing costs for the first seven workshop visits range from $334 to $587, and are undertaken every 12 months or 15,000km (whichever comes first).
