Hyundai I20 vs Mercedes-Benz A35

What's the difference?

The i20 N hatch is so much fun, and not in a special occasion kind of way. It’s an affordable, compact performance car that’ll put a smile on your face no matter where or when you drive it. The Fiesta ST and Polo GTI have a worthy new playmate. I love it!

The Mercedes-AMG A35 sedan is a genuinely fun small car. To me it’s a more mature offering than the A35 hatch, while not being quite as pretentious as a CLA35. Therefore I like it on principle.

Would I personally choose it over an Audi S3? Probably not - but there are plenty of objective reasons why you would.

Hyundai’s current WRC challenger may be a coupe but this angry little five-door hatch absolutely looks the part.

We’re assured the N is the only current-generation i20 we’ll see in the Aussie market, and it runs with a relatively low (101mm) ground clearance, a grille pattern inspired by a chequered flag, black mirror shells, and menacing, angular LED headlights.

The ‘Satin Grey’ 18-inch alloys are unique to this car, as are the side skirts, raised rear spoiler, darkened LED tail-lights, a ‘sort-of’ diffuser under the rear bumper and a single fat exhaust exiting on the right-hand side.

There are three standard paint options - ‘Polar White’, ‘Sleek Silver’, and N’s signature shade of ‘Performance Blue’ (as per our test car) as well as two premium shades - ‘Dragon Red’, and ‘Phantom Black’ (+$495). A contrasting Phantom Black roof adds $1000.

Inside, the N-branded sports seats, trimmed in black cloth, featuring integrated headrests and blue contrast stitching, are unique to the i20 N. There’s a leather-trimmed sports steering wheel, handbrake lever and gear knob, as well as metal finishers on the pedals.

The 10.25-inch digital instrument cluster and same-sized multimedia screen look slick, and ambient lighting heightens the hi-tech mood.

This is the first AMG A-Class sedan ever, so that’s an interesting design decision. I wasn’t sure whether Mercedes needed a CLA ‘Coupe’ and an A-Class sedan to sit alongside one another, but there are distinct differences in terms of the look and intent of the two compact models.

The A sedan carries over the A-Class hatchback’s aggressive styling, with sharp, angular headlights, a strong presence courtesy of its black exterior highlights (including AMG flics on the front bumper and black side skirts, rear spoiler and rear diffuser for this test vehicle). The black 19-inch black-finish rims fitted to our test car are also optional, with silver being the standard finish.

It has a stumpy little boot with a broad stance thanks to its triangulated tail-lights and horizontal reflectors, while the twin exhaust pipes with black tips are rather pleasant to look at, too.

It’s a very attractive sedan, with nothing clumsy about its proportions at all. Is it gorgeous enough to make you think twice about the Audi A3/S3/RS3 as the ruler of the pretty little sedan? Maybe… it’s not quite there for me, although it’s close. But it is certainly a distinct design, one that Merc fans will undoubtedly adore.

The dimensions of the A35 sedan aren’t what a lot of people would actually consider “small”. It’s 4549mm long (on a 2729mm wheelbase), 1796mm wide and 1446mm tall. For context, that’s longer, wider and taller than the substantial Mazda3 small sedan, if not quite as big as the a Corolla sedan.

And if you’re wondering about how that compares to a CLA, that car has the same wheelbase but is 4688mm long, 1830mm wide and 1439mm tall. That’s bigger than a C-Class. Gosh, how confusing. 

What does it all mean when it comes to interior space? Check out the interior images and details below to see for yourself.

Although it’s just 4.1m long, the i20N is impressively space efficient with decent room up front and a surprising amount of head and legroom in the back.

Sitting behind the driver's seat, set for my 183cm position, I had plenty of head and legroom, although, understandably, three people across the back will need to be kids or understanding adults, on a short journey.

And there are plenty of storage and power options, including the wireless device charge pad in front of the gear lever, which doubles as an oddments tray when not in use, two cupholders in the front centre console, door bins with room for large bottles, a modest glove box and a lidded cubby/armrest between the front seats.

No armrest or air vents in the back, but there are map pockets on the front seat backs, and again, bins in the doors with room for bottles

There is a media USB-A socket and another for charging, as well as a 12V outlet in the front, and another USB-A power socket in the back. Hyundai suggests the latter could be handy for powering track day cameras. Great idea!

Boot space is impressive for such a compact hatch. With the rear seats upright there’s 310 litres (VDA) available. Fold the 60/40 split-folding rear backrest and no less than 1123 litres opens up.

A dual-height floor can be flat for long stuff, or deep for tall stuff, there are bag hooks provided, four tie down anchors, and a luggage net included. The spare is a space saver.

I admit, I thought I’d get a bit more in the cabin of the A35 sedan. There’s no electric steering wheel adjustment, no heated steering wheel, and the fact adaptive cruise control is optional (it’s standard on some $25K cars!) is a bit rude, too.

That isn’t to say that it’s not an eye-catching space, one that will hit hard on the bling-o-meter, and will definitely impress anyone who isn’t familiar with Mercedes’ recent cabin design traits.

The twin screens are dazzling - crisp and beautiful to behold, and with graphics that are extremely high resolution. The menus have been designed to be simple, but honestly, it’s a bit confusing until you’re initiated.

Also, I found the media screen to be very glitchy. On multiple occasions it would not respond to touch, and once it even reset itself. I also had several problems connecting to Apple CarPlay. Note: I was using a Mercedes-Benz USB-C adaptor to USB-Lightning cable with an iPhone XS, and I think maybe the adaptor had a part to play in the problems I encountered.

The touchscreen is just one way to interact with the media controls, as there’s a touchpad between the front seats, and the driver has a thumb-controller on the steering wheel to jump between screens. And there’s voice control as well, with the MBUX system’s ‘Hey, Mercedes’ recognition allowing you to ask for things to be adjusted. 

Furthering the wow-factor up front are beautifully designed air vents that light up blue when you turn the temperature down or red when you up the heat. There’s configurable ambient lighting for the cabin, which makes the A35 a bit of a showstopper at night, and our car had the no-cost optional red and black Lugano leather trim, which is either going to be your thing, or not. 

The space for adults up front is decently accommodating, with good headroom and width, plus nice soft touch points where there should be, and there are bottle holders in the doors. There are three USB-C points up front, a pair of cup holders between the seats, and a wireless (Qi) phone charging bay.

The steering wheel is a nice shape and easy to hold, though I’m still not convinced by the little digital displays for the drive-mode dials - they’re toy-like teeny-weeny screens and look a bit pixelated compared to the other displays in the cabin.

Rear seat space is not as good as you might hope or expect, given the size of the car. As a 182cm (6.0ft) man with the driver’s seat set for me, my knees were hard against the seat in front, my toes were squashed and my head was just brushing the headliner, too.

That mightn’t be a problem for you - maybe your only rear seat riders will be short, or young. There are dual ISOFIX child-seat anchor points and three top-tether restraints for baby seats, if that’s the case.

And they’ll be well catered for, with a pair of USB-C ports, as well as directional air-vents, mesh map pockets, and bottle holders in the doors as well as a fold-down armrest with pop out cup holders.

Boot space will likely matter to you if you’re buying a sedan over the hatchback model, and you’ll find an additional 60 litres of boot space here over the five-door model, with 430L of cargo capacity.

That should, in theory, be large enough to fit all three of the CarsGuide cases (124L, 95L, 36L), but the shape of the cargo hold meant I only managed to fit the smallest case with the middle or largest case, but not all three together. Soft luggage could help.

There’s no spare wheel under the boot floor, as the A35 has a tyre repair kit. 

The Mercedes-AMG A35 4Matic sedan has a list price of $72,500, which is the manufacturer’s recommended list price (MRLP, also known as MSRP). That’s the price before on-road costs and extras.

What cars does the A35 compete with? The most obvious rival is one from within, the Mercedes-AMG CLA35, which is $85,500. Then there’s the Audi S3 sedan ($65,800) or RS3 sedan ($86,500). Or the BMW M235i Gran Coupe, which is actually its closest competitor on price, at $72,990. 

You might have made your mind up about wanting the three-pointed-star badge though, so what do you get for your cash when it comes to the A35 sedan?

The standard equipment includes: 19-inch wheels, AMG body kit and 'Night Package' (blacked-out exterior trim), Lugano leather seat trim, heated and electric adjust front seats, keyless entry and push-button start, adaptive AMG Ride Control suspension, AMG drive modes, ambient lighting and a panoramic sunroof.

The cabin is equipped with a pair of 10.25-inch screens - one controlling media via the brand’s MBUX system and featuring Apple CarPlay and Android Auto, and the other a configurable display for driver info. There’s sat nav, five USB-C ports, wireless phone charging, and a nine-speaker sound system.

Other features include an auto-dimming rearview mirror, LED headlights and daytime running lights, semi-autonomous parking, front and rear parking sensors, a reversing camera and a number of active safety items beyond that. See the safety section below for more info.

Our car had a couple of options, including: black-finish 19-inch alloy wheels ($790); the 'Driving Assistance Package' - incorporating adaptive cruise control with front and rear cross-traffic alert, active lane-change assist, and 'Route-Based Speed Adaptation' - more on that below ($1890); the 'Vision Package' - with 'Multibeam LED' headlights and selective adaptive high beam assist, and a 360-degree surround view camera ($990); and the 'AMG Aerodynamics Package' - with front flics, side skirt trims, rear spoiler and rear diffuser ($2490).

All told, the as-tested price for this car was $78,660 plus on-roads.

The i20 N is powered by a turbo intercooled 1.6 litre four-cylinder petrol engine, driving the front wheels via a six-speed manual gearbox and Torsen-type mechanical limited slip differential.

The all-alloy (G4FP) engine features high-pressure direct-injection and an overboost function, producing 150kW from 5500-6000rpm, and 275Nm from 1750-4500rpm (rising to 304Nm on overboost at max throttle from 2000-4000rpm).

And the engine’s mechanical ‘Continuously Variable Valve Duration’ set-up is something of a breakthrough. In fact, Hyundai claims it as a world’s first for a production engine.

Not timing, not lift, but variable duration of valve opening (managed independently of timing and lift), to strike the optimal balance between power and economy across the rev range.

You could look at this one of two ways: 1) this is the least powerful AMG on sale today; 2) this is a seriously powerful small car.

If you’re glass-half-full-biased like me, you’ll see the engine specs and park yourself in the latter camp. 

There’s a 2.0-litre turbocharged four-cylinder petrol motor which isn’t short on horsepower: it has 225kW of power and 400Nm of torque - those were class-killing power outputs not too long ago. 

The grunt numbers give the AMG A35 sedan a claimed 0-100km/h time of just 4.8 seconds, while the top speed is limited to 250km/h. Five years ago these power figures and performance numbers would have pegged the A35 in A45 territory - this is a seriously powerful little jigger.

The engine is teamed to a seven-speed dual-clutch automatic transmission, and the A35 runs Benz’s 4Matic all-wheel drive system, which is front-biased but can shuffle torque 50:50 if needed. 

Hyundai’s official fuel economy figure for the i20 N, on the ADR 81/02 - urban, extra-urban cycle, is 6.9L/100km, the 1.6-litre four emitting 157g/km of C02 in the process.

Stop/start is standard, and we saw a dash-indicated average of 7.1L/100km over several hundred km of city, B-road and freeway running on the occasionally ‘spirited’  launch drive.

You’ll need 40 litres of ‘standard’ 91 RON unleaded to brim the tank, which translates to a range of 580km using the official figure and 563 kays using our launch test drive number.

The combined cycle fuel consumption figure - that’s what the brand says the car will use over a mix of driving - is 7.4 litres per 100 kilometres.

I saw a little higher than that over my 650km of driving, which was heavily biased towards highway testing, but also included a few traffic snarls and a couple of stints of performance testing. I saw 8.4L/100km, which is okay, but I expected better given 80 per cent of my time in the car was in easy-going open road driving.

The fuel tank capacity for the A35 sedan is 51 litres, and you’ll need to fill it with 98 RON premium unleaded petrol. 

Unusually for a manual car, the i20 N features a launch control system (with an adjustable rpm setting), which we found fiddly to get working, but with or without it, Hyundai claims a snappy 0-100km/h time of 6.7sec.

And it’s such a pleasure to steer a car with a slick-shifting manual gearbox. The six-speed unit features a rev-matching function accessed via the press of a racy red button on the steering wheel. 

Buf for those who prefer an old-school, double-shuffle, heal-and-toe tap dance across the pedals, the relationship between the brake and accelerator is perfect. 

And if you’re keen on Walter Rohrl-style left-foot braking, to help steady the car or steer it in fast cornering, the ESC is switchable through to Sport mode or completely off, allowing fuss-free simultaneous brake and throttle application.

There’s even a shift-timing indicator near the top of the instrument cluster, with colour bars closing in on each other as the tacho needle pushes towards the rev limiter. Fun.

Engine and exhaust noise is a combination of a raspy induction note and adjustable crackle and pop out the back, courtesy of a mechanical flap in the exhaust system, adjustable through three settings in N mode.

Traditionalists may not be thrilled by the addition of in-cabin synthetic enhancement of all of the above, but the net effect is thoroughly enjoyable.

It’s worth remembering in this context N stands for Namyang, Hyundai’s sprawling proving ground south of Seoul where the car was developed, and the Nürburgring where this go-fast i20 was fine-tuned.

The body has been specifically reinforced at 12 key points, along with additional welds, and “bolt-in underbody structures” to make the i20 N stiffer and more responsive.

The strut front, coupled (dual) torsion beam rear suspension has also been set up with increased (neg) camber and a revised anti-roll bar at the front, as well as specific springs, shocks and bushings.

A compact, mechanical LSD is added to the mix, and grippy 215/40 x 18 Pirelli P-Zero rubber was produced specifically for the car and is stamped ‘HN’ for Hyundai N. Impressive.

The end result is outstanding. Low-speed ride is firm, with suburban bumps and lumps making their presence felt, but that’s what you’re signing on for in a hot hatch at this price point.

This car feels balanced and well buttoned down. Power delivery is agreeably linear and at a fraction over 1.2 tonnes the i20 N is light, responsive and nimble. Mid-range urge is strong.

Steering feel is good, with assistance from a column-mounted motor taking nothing away from an intimate connection with the front tyres.

The sports front seats proved grippy and comfortable over long stints behind the wheel, and playing with the multiple N drive modes tweaking the engine, ESC, exhaust, and steering just adds to the involvement. There are twin N switches on the wheel for quick access to custom set-ups.   

And that Torsen LSD is brilliant. I tried my best to provoke a spinning inside front wheel on the exit of tight corners, but the i20 N just puts its power down without so much as a chirp, as it rockets towards the next bend.

The brakes are 320mm vented at the front and 262mm solid at the rear. Calipers are single piston, but they’ve been beefed up and fitted with high-friction pads. The master cylinder is bigger than the standard i20 and the front rotors are cooled by lower control arm mounted air guides blowing through vented knuckles.

The launch i20 N fleet of around half a dozen cars copped an hours long hot lap pounding at Wakefield Park Raceway, near Goulburn NSW without drama. They’re well up to the task. 

One niggle is a large turning circle. The data sheet says 10.5m but it feels like the car is carving a wide arc in U-turns or three-point turns.

A 2580mm wheelbase between the bumpers of a 4075mm car is substantial, and the steering’s relatively low gearing (2.2 turns lock-to-lock) no doubt has a lot to do with it. The price you pay for quick turn-in.

On paper this seems like the ideal option for those who know they’ll never really be able to take advantage of the outputs of an A45 or CLA45’s ludicrous power and torque figures.

In practice? It mostly lives up to that notion - though just like an A45 or CLA45, you’re going to enjoy it a lot more when you’re giving it the beans. 

Driving with intent, the engine and transmission work together amazingly well. The transmission itself is thoughtful and smart shifting, swapping cogs exactly when you think it should - while you have paddle shifters available to use, in most cases you’re not going to need them.

The engine itself is an absolute weapon. There’s lots and lots of pulling power, it’s linear in the way it delivers its power, and there’s a little bit of pop and crackle from the exhaust - personally, I would like even more. I guess that’s where an A45 or CLA45 comes into its own.

The steering is superb for an all-wheel drive car, too. It’s direct and accurate, and while you can feel the electronics shuffling the power and torque between front and rear axles it’s a really nicely balanced and very easy car to drive fast – at times even faster than you really should be. 

In Sport mode and Sport Plus mode the suspension and steering are tightened up, with taut responses but the suspension is never crunchy or uncomfortable. Braking performance is very good, too.

In Comfort mode though, I struggled to come to terms with the A35 a little. In my mind, it lived up to the notion of a sporty sedan a lot more readily than it did that of a compact luxury sedan. It just feels like it’s meant to be on a twisty road, not dealing with daily drudgery in commuting.

One not-very-luxurious element was the road noise intrusion, which was the worst of any new car I can recall experiencing. That might seem a dramatic claim, but the booming tyre roar on coarse chip road surfaces, including major Sydney freeways, was verging on unbearable. I measured it on my smartphone, and 78 decibels was the maximum readout.

And while very impressive under pressure, the powertrain is somewhat doughy in less demanding situations. There’s some lag to contend with, and a little bit of lunging from the transmission, too. However, it was during downshifts that I found the transmission’s behaviour most questionable, with some shift-shunts when slowing to a halt in urban driving. 

One unexpected finding was the 'Route-Based Speed Adaptation' system’s behaviour, which was active in the car I was driving. The tech uses the car’s mapped position to guide its adaptive cruise control behaviour. In theory it’s a very smart idea - the car will slow itself down if it predicts you’re about to approach a tight bend and you’ve got it set at the speed limit. Or if you’re approaching a roundabout, it’ll think ahead, too.

But during my time in the car, I had an issue that I found could be potentially dangerous. Having set the speed at 80km/h in a relatively new tunnel in Sydney’s west (the WestConnex M4, opened July, 2019), the system couldn’t place the car’s location, which meant the car believed it was still on surface streets. 

On multiple occasions the car slowed dramatically thinking I needed to turn a corner that didn’t exist on the road I was driving on. My instant thought was: “What if the person behind me wasn’t looking at the road ahead?” I’ve seen enough drivers with their eyes aimed at the phone in their lap and not the road ahead, to know this is a distinct possibility.

There’s also a risk from tailgating trucks, which seem to be more prevalent in Sydney’s west than anywhere else on the planet. It’s a potential risk, even if the Benz has clever tech that can flash the tail-lights if the car’s systems predict there’s a chance of being rear-ended.

Mercedes-Benz’s Aussie team let me know that the map software wasn’t up to date, which is why the car didn’t understand the situation. It’s technology you can disable by simply delving into the menus on the MBUX system, but I’d recommend you try it out to see if you’re comfortable with it.

The A-Class range was awarded the full five-star ANCAP crash test rating based on 2018 criteria, and the scoring measures have progressed since then. According to ANCAP, the rating applies to all Mercedes Benz A-Class variants, though the Mercedes-AMG A35 (hatch and sedan) and A45 (hatch) are not shown on the scorecard.

However, the entire A-Class range comes with auto emergency braking (AEB) that operates between 7-200km/h and has pedestrian and cyclist detection (7-50km/h), active lane keep assist (LKAS, 0-250km/h) and lane departure warning (LDW), traffic sign recognition (TSR), and blind spot monitoring (BSM) and rear cross traffic alert (RCTA) with auto-braking. There’s also driver fatigue monitoring, cruise control with speed limiter, and speed sign recognition.

But despite being the top-of-the-range A-Class sedan, you still have to pay extra for the safety of front cross traffic alert with braking, and the brand’s Distronic adaptive cruise control system. Those are part of the Driving Assistance Package ($1890), which also incorporates active blind spot assist, active lane change assist, a system called Evasive Steering Assist (which sharpens up the steering to be more direct if a crash threat is predicted), and the aforementioned Route-Based Speed Adaptation.

Hyundai covers the i20 N with a five year/unlimited km warranty, and the ‘iCare’ program includes a ‘Lifetime Service Plan’, as well as 12 months 24/7 roadside assist and an annual sat nav map update (the latter two renewed free-of-charge each year, up to 10 years, if the car is serviced at an authorised Hyundai dealer).

Maintenance is scheduled every 12-months/10,000km (whichever comes first) and there’s a pre-paid option which means you can lock in prices and/or fold service costs into your finance package.

Owners also have access to the ‘myHyundai’ online portal providing details on the car’s operation and features as well special offers and customer support.

Service for the i20 N will set you back $309 for each of the first five years, which is competitive for a hot hatch in this part of the market. 

Mercedes-Benz Australia recently joined Korean luxury brand Genesis in meeting the market with a five-year/unlimited kilometre warranty plan for all of its models, including AMG variants.

Service intervals for the A35 sedan are set every 12 months/25,000km - yes, that’s a generous maintenance schedule, as most cars require servicing every 15,000km. 

Buyers can opt to pre-pay servicing costs and roll it into their finance package, and there’s a level of discount applied if you do that. 

For a three-year/75,000km service plan, you’ll pay $2150, saving you $500 over pay-as-you-go capped price servicing. There’s also a four-year/100,000km plan ($2950) or a five-year/125,000km plan ($4000). That’s surprisingly decent for a luxury car, though keep in mind it doesn’t include wiper inserts or brake pads/discs.

Buyers get roadside assistance included for the duration of the new-car warranty, too.
