Mercedes-Benz A45 vs Hyundai I30

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.

The updated Hyundai i30 N Line doesn’t look like or perform like a base model.

You really do get bang for your buck here with its features. It’s a good-looking hatch that’s fun to drive in the city or open road and while the multimedia system is basic and occupants will be squished in the rear row, everything else is a big plus.

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.

The design memo seems to be to make the i30 N Line look sportier and more purposeful.

They've nailed the design. The i30 is a good-looking hatch that looks like it has European styling.

The reshaped grille features new air intake vents, and stylish V-shaped daytime running lights. The rest of the body looks sharply dressed with new side skirts, reshaped bumper, black side mirrors, dual exhausts and 18-inch alloy wheels.

The cabin has been refreshed with a black headliner, upgraded leather and suede upholstery with contrasting red stitching and an N Line steering wheel and leather gear shifter.

The dashboard features new materials and additional soft touchpoints that make the interior feel like it's not a base model at all.

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).

Like most hatches, the front row of the i30 benefits the most when it comes to leg- and headroom. Taller passengers will be most comfortable up front as the rear row doesn't offer all that much legroom. It's squishy behind my driving position and I'm only 168cm tall!

Access however is decent for both rows because of the wide door apertures, but it's a low car to get in and out of because of the 140mm ground clearance. Expect a couple of grunts after a gym session.

The seats in both rows are fairly well-padded and offer the most comfort on shorter journeys. Even with the new powered lumbar support on the drivers seat, fatigue can set in quickly on a longer trip.

Individual storage is excellent throughout the car with a large glovebox that can hold a thick manual, middle console, phone tray, four cupholders, a drink bottle holder in each door, two net map pockets and even a sunglasses holder!

Other than the Kia Cerato, the i30 has one of the largest boots compared to its rivals, at 395L, and it’s enough for road trips and a decent grocery haul. The taller boot lip means you can stack items too but you don’t get a spare wheel in this model, just a tyre mobility kit. The base model also doesn’t get a powered tailgate, but the lid is not heavy at all to operate.

The new digital instrument cluster looks great but the multimedia system is basic and there’s no satellite navigation, so you're reliant on the phone mirroring apps but these maintain a strong connection. The radio is a hit or miss but that’s typical for the grade level.

Charging options are great for a base model with a single USB-A port, three USB-C ports and 12-volt sockets, and a wireless charging pad to choose from.

There are two models for the 'regular' i30 and we’re testing the base model, the N Line. Its new price point of $36,000, plus on-road costs, means it's $8940 more expensive than the most affordable rival, the Kia Cerato hatch.

The Mazda 3 Pure hatch is the next at $30,470 and then comes the Toyota Corolla Ascent Sport at $32,110.

However, the base models differ greatly in terms of standard features and the updated i30 N Line delivers upgraded leather and suede upholstery as opposed to the standard cloth. There are now two-USB-C ports in the rear, and a 10.25-inch digital instrument cluster that comes standard.

The driver also gets extendable under-thigh and powered lumbar supports to increase comfort.

Key features include wired/wireless Apple CarPlay and Android Auto, keyless entry and start, rain-sensing wipers and dusk-sensing LED headlights. Anyone familiar with base models might know that a lot of those items are not standard features and it’s nice that you don’t have to go up a grade level or two to get them in the new i30 N Line, although you are paying more in the first place.

Other standard features include an 8.0-inch touchscreen multimedia system, dual-zone climate control, a USB-A port, three USB-C ports, three 12-volt sockets, a wireless charging pad, digital radio and a six-speaker sound system.

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 updated i30 N Line has a new mild-hybrid powertrain that features a 1.5-litre 7 four-cylinder turbo-petrol engine and combines to produce 117kW and 253Nm of torque. This new combo means it has higher outputs than its nearest rivals and you get three drive modes, including Sport which makes those outputs feel even more prevalent.

Like its rivals, the i30 N Line is a front-wheel-drive, but it has a seven-speed dual-clutch transmission which can sometimes feel like it's confused in stop/start traffic.

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.

The new engine coasts in neutral when you’re not accelerating to improve efficiency and it works for that purpose as my real-world usage of 6.3L/100km isn't too far off the official combined fuel cycle figure of 5.6L.

Based on the official combined fuel cycle and 50L fuel tank, you should see a theoretical driving range of up to 893km, which is downright respectable.

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 new powertrain is impressively punchy and you almost feel like you’re driving a hot hatch when you hit the open road because it’s effortless to keep up and overtake when necessary. 

The steering is firmer than what you’d expect and that makes the car feel heavier than what it is. Cornering is great – barely any roll – but the suspension is not finely tuned, especially for regional roads. But the overall feel is sporty, so it’s forgivable. 

At lower speeds, the cabin is delightfully quiet and although the exhausts are thrumming with noise, you don’t really hear it! It’s only once you get on the open road that the road noise creeps up but you can hold a convo without raising your voice, so that’s still good.

The i30 is pretty low to the ground and that makes it easy to scrape the bottom of it, especially when you have a full car load, so take ramps and bumps at a slight angle.

Hatches are always the best for parking because you can park ‘em anywhere! The i30 N Line has front and rear parking sensors and a decent reversing camera, so it’s extra easy.

The i30 has a maximum five-star ANCAP safety rating from testing done in 2017 and features seven airbags but, like its rivals, it doesn’t have a front centre airbag yet. 

Safety features includes items which are often at cost extras for a base model, like blind-spot monitoring and rear cross-traffic alert.

Other standard items include driver attention warning, safe exit warning, rear occupant alert, tyre pressure monitoring, DRLs, lane departure alert, lane-keeping aid, traffic sign recognition, intelligent seatbelt warning, adaptive cruise control, a reversing camera system as well as front and rear sensors.

The lane keeping aid and traffic sign recognition tech are a bit intrusive for daily driving but easy enough to adjust if need be.

The i30 model has two ISOFIX child seat mounts and three top tethers but two seats will fit best.

AEB with forward collision warning is standard but ANCAP does not stipulate it's operational km/h range.

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.

Hyundai offers the i30 with a five-year/unlimited km warranty, which is a normal term for the class and you can pre-purchase three-, four- or five-years worth for servicing and the five-year option cost $1795, which is competitive. 

Servicing intervals are okay at every 12 months or 10,000km, whichever occurs first.
