Hyundai I20 vs Toyota Corolla

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!

After several years in market, the Toyota Corolla Ascent Sport Hybrid stands up well. Late 2022 upgrades have helped keep the hybrid powertrain on the pace and the multimedia system competitive. The sedan layout is better than the hatch for carrying people and cargo, it’s a refined and comfortable drive, and the ownership package sets the pace in this category. That said, safety is good but could be better, the CVT’s a bit drony, there are some small things we’d like to see on the standard equipment list (adjustable rear ventilation, extra USBs) and there’s room for improvement in terms of in-cabin storage. But overall, it’s hard to go past this small sedan proposition.

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.

The current Corolla sedan arrived in late 2019, a bit over a year after the hatch, and the car’s dramatic face with long angular headlights and huge lower grille has held up well.

Always a subjective call, but I think it still looks fresh and distinctive, in the case of the sedan, balanced by a less complex rear treatment, no doubt applied with a four-door buyer’s typically more conservative tastes in mind.

Worth noting for an entry-grade model our Ascent Sport looked particularly classy in ‘Atomic Rush’, a sedan-only body colour, and overall the car’s ‘three-box’ proportions are well balanced, helped by the base car’s step up from 15- to 16-inch alloy wheels in the 2022 upgrade.

The interior is simple without crossing over into plain, the dual-level dash design accommodating an 8.0-inch media screen standing proud in the centre, and a compact instrument binnacle sitting under a curved brow.

The grey fabric seat trim looks tough but doesn’t feel it, with some squiggly quasi-quilting in the centre panels adding visual interest. The only other hint of flashiness being gloss black finish panels in the centre console, around the ventilation controls and media screen.

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.

At just over 4.6m long, close to 1.8m wide and a fraction over 1.4m tall, the Corolla sedan is a ‘big’ small car. And at 2700mm, the sedan’s wheelbase is 60mm longer than its hatch equivalent.

There’s plenty of breathing space up front and storage runs to generous door bins with space for large bottles, two cupholders in the centre console, a lidded box (which doubles as a centre armrest) between the seats, a decent glove box and the wireless charging tray in front of the gearshift. That’s all fine, but some extra oddments space in the centre console would be nice.

Move to the rear and the sedan’s extra wheelbase length manifests itself in the shape of noticeably more room than the hatch.

Sitting behind the driver’s seat set for my 183cm height, I enjoyed good legroom and ample headroom. Three adults will be okay for short to medium journeys and a trio of up to teenage kids will be fine for the long haul.

There’s a fold down armrest with two cupholders built in, although the cushion lowers all the way onto the seat creating a slightly awkward downward angle. And no map pockets on the front seat backs feels a bit stingy.

The rear door bins can accommodate a medium-size bottle and a small tray at the back of the front centre console is where you’d like the adjustable ventilation and USB outlets to be, but sadly, they don’t exist.

In fact, power and connectivity options number just two; a USB-C socket in the front for charging and media connection as well as a 12V outlet in the front centre storage box. 

Modest boot space is an Achilles Heel for the Corolla hatch, but the sedan’s 470 litres of cargo volume is way better.

It swallowed our three-piece luggage set or the bulky CarsGuide pram with room to spare, and the 60/40 split-folding rear seat lowers to liberate extra space. Just bear in mind that the relatively tight aperture is a large-load disadvantage relative to a wide-opening hatch door.

Interestingly, there aren’t any tie-down anchors in the boot to secure loads, but there’s a space-saver spare under the floor.

Also worth noting the Corolla Hybrid a no-tow zone. If you need to hook up a boat or campervan, the 2.0-litre non-hybrid Corolla sedan is rated for a 1300kg braked trailer (450kg unbraked).

As mentioned, small sedans aren’t exactly thick on the ground in the Aussie new-car market, but there are three similarly-sized four-doors in close range to this Corolla Ascent Sport Hybrid’s $32,110 (before on-road costs) asking price.

Namely the Kia Cerato Sport+ ($31,440), Mazda 3 G20 Pure Vision ($32,320) and Subaru Impreza 2.0i-S ($32,590).

None can match the Corolla’s hybrid efficiency, but each is well equipped for a small car in the low $30K bracket and the Corolla takes a lengthy equipment list into battle against them.

Aside from the performance and safety tech covered a little later, the Ascent Sport Hybrid’s standard features include an 8.0-inch touchscreen multimedia display with voice control, Android Auto and (wireless) Apple CarPlay, six-speaker audio with digital radio and in-built satellite navigation.

There’s also climate control air (single-zone), a 7.0-inch information display in the instrument cluster, keyless entry and start, wireless phone charging, active cruise control, an electro-chromatic rear view mirror, 16-inch alloy wheels, LED headlights, tail-lights and DRLs as well heated door mirrors.

The seat trim is fabric and for things like rain-sensing wipers, side and rear privacy glass, as well as a ‘Premium’ steering wheel, you’ll need to step up the SX Hybrid Sedan at $33,780. But the Ascent Sport lines up well relative to its direct competitors.

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.

The Corolla hybrid is powered primarily by a naturally aspirated 1.8-litre four-cylinder petrol engine operating on the ‘Atkinson Cycle’, which adjusts cam timing to maximise the effective cylinder expansion ratio (compression stroke vs power stroke) for greater efficiency and reduced emissions.

But the downside of this combustion cycle is a relative lack of power, which is where the car’s primary AC synchronous, permanent magnet electric motor comes into play.

Upgraded in late 2022, the motor now features double the number of magnets (per pole) inside the rotor.

At the same time a lighter lithium-ion battery was added, featuring greater input and output power compared to the nickel-metal hydride unit it replaced.

A compact starter/generator (effectively a second electric motor) is powered by the engine (it also starts it) in turn sending energy to the main drive motor and battery. 

The end result is combined outputs of 103kW (+13kW) at 5200rpm and 142Nm at 3600rpm, although it’s worth noting Toyota has a strange habit of not including the torque output from the electric motors in its overall numbers for hybrid models.

With the primary motor alone producing more than 160Nm of pulling power, you’d have to imagine the actual combined torque figure is somewhere in the region of 250Nm, with drive going to the front wheels via a CVT auto.

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.

Toyota’s official combined cycle fuel economy number for the Corolla’s hybrid powertrain is 3.9L/100km, the 1.8-litre engine emitting 81g/km of CO2 in the process.

That’s up slightly from the pre-upgrade model’s 3.5L/100km claim, but over a week with the Ascent Sport we covered around 250km of urban, B-road and some freeway running, returning an average of precisely 3.9L/100km (at the bowser), which is an outstanding result for a close to 1.4-tonne four-door sedan.

Of course, the super smooth stop-start system (controlled by the starter/generator) plays a part, plus the bonus is the 1.8-litre four is happy to accept ‘standard’ 91 RON unleaded, and the fuel tank holds 43 litres, which translates to a range of just over 1100km. Pretty great.

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.

The Corolla Ascent Sport Hybrid is a comfortable, stress-free driving experience. Toyota’s series parallel hybrid set-up means the wheels can be driven by the internal-combustion engine, electric motors, or both. And the transition happens seamlessly.

Start-up is silent with the motor(s) doing the driving at low speed, the petrol engine kicking in as the power requirement rises.

As the engine operates it’s also charging the battery and under braking the front wheels turning causes the motor and generator to send power to the main battery pack, as well.

Toyota doesn’t quote acceleration figures for the Corolla but you can expect 0-100km/h in around 12 seconds, which is hardly neck-snapping, however this hybrid combination provides enough torque for nimble acceleration in the city and suburbs as well as easy freeway cruising.

Then there’s the Continuously Variable Transmission. I’m no CVT fan, largely because of the disconnect between road speed and engine speed it creates. The transmission is always trying to keep the engine in its efficiency sweet spot and the most noticeable byproduct is an incongruous droning sound.

Developed by transmission specialist (and Toyota subsidiary) Aisin, the Corolla’s unit is ‘tighter’ than some but the sluggish ‘slipping clutch’ effect is still there from time to time.

Underpinned by Toyota’s TNGA platform, precise handling and excellent ride comfort are dynamic hallmarks of this 12th-generation Corolla. And the Ascent Sport Hybrid Sedan is no exception.

Suspension is by struts at the front and multi-links at the rear, and compliance is super impressive, especially for a car of this size.

The electrically-assisted steering is responsive and road feel is good, the car remaining planted and predictable, with only modest body roll if the red mist descends and you decide to ‘push on’ through your favourite set of corners.

This kind of response is especially noteworthy given the car’s low-rolling resistance Bridgestone Ecopia rubber (205/55) is primarily designed for efficiency rather than race-circuit grippiness.

Braking is by 255mm ventilated discs at the front (slightly smaller than the 2.0L non-hybrid’s) and 265mm solid rotors at the rear. They’re progressive with good pedal feel. Not always the case when regenerative braking is part of the picture.

In terms of general comfort and ergonomic efficiency, the seats remain comfortable, even over road-trip-style stints, while the mix of physical and digital controls is sensible and works well.

The Corolla Ascent Sport Hybrid Sedan boasts a maximum five-star ANCAP rating, although the assessment was in 2018 and the criteria have been dialled up since then.

That said, active (crash-avoidance) tech includes AEB - operating from 10-180km/h (with pedestrian and cyclist detection from 10-80km/h), active cruise control, lane trace assist, lane-keep assist, emergency lane keeping, road sign assist and auto high beam. 

‘Active Cornering Assist’ and a reversing camera are also standard, but sadly, blind-spot monitoring (with ‘Safe Exit Assist’) and rear cross-traffic are optional.

If a crash is unavoidable, there are seven airbags on board (front, front side, full length curtain and driver’s knee). No front centre bag, though.

There are three top-tethers across the back seat for baby capsules or child restraints with ISOFIX anchors on the two outer positions.

Also fitted is a manually-triggered, roof-mounted SOS button for a back-to-base call that can direct emergency services to the vehicle's location if required.

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. 

Toyota covers the Corolla with a five-year, unlimited-km warranty, which is the industry standard these days. But significantly, the hybrid battery is included and if you follow the annual servicing schedule for those five years, your engine and driveline warranty extends to seven years and the battery to 10 years (if the latter is also inspected annually). Impressive.

Seven years emergency assistance is provided (expenses related to car hire or towing), and corrosion (to the point of perforation) is covered for seven years.

On top of that ‘Toyota Connected Services’, accessed through the ‘myToyota’ app, is complimentary for 12 months, offering everything from vehicle data and member discounts to driving insights and multimedia profiles.

Servicing is recommended every 12 months or 15,000km, and ‘Toyota Service Advantage’ capped pricing is available, with the number sitting at $245 for the first five visits to the workshop. 

That’s up from $175 when the current generation Corolla launched here in 2019, but it’s still a sharp price.
