Toyota Corolla vs Hyundai I30

What's the difference?

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.

Big boots to fill? The Hyundai i30 Sedan N stomps its authority with charming confidence and admirable talent. It’s hard to believe one of the biggest challengers to the i30 N hatch comes from its oddly-styled booted cousin. It’s just as thrilling, immersive, enjoyable and easy.

Which means that, if you’re in the market for a performance hot-hatch, it’s time for the sedan version to step into the limelight and be on your shortlist. It’s another N superstar.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

Now, with hot hatches, more usually means less, with spoilers quite literally living up to their name by blighting an otherwise clean and attractive design. For some, anyway. Under the radar and all that.

But the attention-crazy (CN7) i30 Sedan – known otherwise as the seventh-generation Elantra pretty much most other places around the world – seems like the work of a protractor-brandishing origamian who would not down pencil and stop.

Which means that, in the N’s case, more might actually be more, because all the racy extras enhance the appearance of a very distinctively/divisively-designed sedan.

The blacked-out bumper treatment, red brake calipers, side skirts and handsome alloys draw the eyes away from the odd creases and angles that define the i30 Sedan.

The result is a striking four-door fastback that comes into its own. One might suspect the original drawings were of a slammed-down N, with the overtly sporty stuff removed for the necessary lesser grades that most people end up buying.

Which would be a case of less being less!

Anyway, let’s check out the interior.

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).

Germany's small hot-sedan rivals would struggle to match the i30 Sedan N’s sheer practicality.

Running on a newer-generation architecture also shared with the latest Hyundai Kona, the result is a substantially larger, longer and wider proposition than the 2017-vintage i30 N hatch.

Upshot? The driver and passenger have plenty of space to stretch out in, within a palpably more contemporary cabin than presented in the five-door version. It feels like a car from the next size and decade up.

Being the i30 flagship, the N Premium’s dashboard is also dressed up to look suitably upmarket, angled towards the driver and offering twin 10.25-inch screens, with N-specific configurable instrumentation right ahead of the driver. Blue-stitched leather trim and darker cabin elements also set a racier ambience.

Predictably, there’s a comprehensive performance monitor within the touchscreen with all sorts of vehicle and driving data, including a lap timer. Clever if distracting. You might also take note of the big red button under one of the steering-wheel spokes, cringingly labelled NGS for ‘N Grin Shift’.

It brings a modest 7.0kW power boost, lasting only 20 seconds. Great for instant overtaking oomph, presumably.

Speaking of fast driving, lowered sports seats provide sufficient bracing through tight corners and extra ceiling clearance for helmets, while feeling sumptuously supportive the rest of the time. They're quite terrific.

Beyond these, all the regular sensible features found in more-humdrum i30 Sedans – an excellent driving position, ample ventilation, decipherable controls and stacks of useful storage – are also present.

The same applies across the generous back seat area, which lacks nothing for expected amenities to help keep kids of all ages safe, comfy, hydrated, ventilated and connected, while the N’s slightly-smaller boot (down 10 litres over the regular i30 Sedan) is still large enough for most needs at 464L. Blame the chassis stiffness brace back there.

Meanwhile, a space-saver spare lives underneath the wide, flat floor.

Complaints? The longitudinal buttress that runs along the left side of the centre console by the front passenger seat can constrict knee movement. Driver rear vision is poor, while that sloping back-door aperture makes getting in and out a head-banging affair for taller or bouffant-wearing folk.

Otherwise, the i30 Sedan N boasts a well-resolved cabin.

Does it ever!

Regardless of whether we’re talking about a manual or auto, the facelifted i30 Sedan N for 2024 is only available in the one Premium grade, kicking off from $52,000, before on-road costs.

And though now costing a bit more than before, if it’s a booted hot-hatch experience you seek, then this Hyundai has few rivals. And all are all-wheel drive and not front-wheel drive.

The most obvious is the excellent, if slightly less-powerful, Subaru WRX, which – from just $45,990 for the manual – must be considered an incredible bargain. But the Sport auto version for $4000 extra more-closely mirrors the Hyundai’s specification.

After that… there’s Germany. Consider the Mercedes-AMG A35 sedan, but that represents a near-$40K jump. Plus, you’re also approaching $90K before you can get the Merc’s compatriot competitors – Audi’s sleek S3 quattro and BMW's M235i xDrive Gran Coupe – on the road.

This, then, leaves just the WRX as the Hyundai’s sole affordable four-door sedan alternative for hatch-averse buyers.

So, what’s changed in the i30 Sedan N for 2024?

Along with new LED lights featuring Hyundai’s now-signature full-width light bar, it gains new bumpers and alloys, a strengthened body structure, an array of detailed steering and suspension modifications, upgraded driver-assist safety tech and updated multimedia including USB-C ports.

Note, too, the arrival of real-time connected car services Hyundai calls 'Bluelink' that can locate your car or notify emergency services automatically if you’ve had a prang, among other handy things.

These come on top of all the regular N gear, like the striking body kit, electronically controlled suspension, mechanical limited-slip differential (LSD), bespoke performance driving modes, bigger ventilated brake package and special Michelin Pilot Sport tyres.

Premium also heralds the usual expected luxuries, such as adaptive cruise control, heated and vented sports front seats, leather upholstery, dual-zone climate control, ambient lighting, 19-inch alloys and pretty much all of the electronic driver-assist tech in Hyundai's cupboard. See the safety section below for an expanded explanation.

The only options are a $2000 sunroof and $595 premium paint.

That’s all pretty compelling value-for-money, especially for a car this size… and abilities. More on that later.

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.

Make no mistake. Under the bonnet beats the absolute heart and soul of the Hyundai i30 Sedan N.

The engine carries over from before – a 1998cc 2.0-litre turbocharged four-cylinder direct-injection unit, making 206kW of power at 6000rpm and 392Nm of torque between just 2100 and 4700rpm.

Tipping the scales at 1475kg, the resulting power-to-weight ratio is an impressive 140kW/tonne. And, don’t forget, pressing the N Grin Shift unleashes an extra bit of power, bumping the total up to 213kW for a 20-second burst.

The 0-100km/h sprint time takes 5.3 seconds, on the way to a 250km/h top speed.

Refreshingly, traditionalists can still choose a six-speed manual (albeit with a rev-matching function), or eight-speed wet-type DCT dual-clutch auto transmission, and both drive the front wheels via an electro-mechanical limited-slip differential.

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.

The i30 N DCT’s official combined average consumption is 8.3 litres per 100km, for a carbon dioxide emissions rating of 194g/km.

Around town, that consumption figure shoots up to 11.8L, and drops to 6.3L outside of urban areas. Add 0.2L apiece for the less-efficient (but more-engaging) manual version.

Filling the 47L tank, with 95 RON premium unleaded petrol, you could exceed 565km between refills on average.

With a combination of gentle highway schlepping and blasting through the hills around the fast Murray River-area rural roads, our trip computer indicated a commendable 10L/100km – given this car’s 250km/h performance.

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.

Out about the hilly roads around Albury/Wodonga, the i30 Sedan N feels in its absolute element. The mixture of long open straights and tight corners really show off Hyundai’s incredible chassis tuning capabilities.

i30 Sedan N improvements for 2024 include brakes with better cooling and resistance to fade, stronger engine mounts for improved agility, more insulation, reduced vibrations, upgraded steering components for even more-precise handling and tweaks to the stability control system for more-effective operation.

Suspension is by McPherson-style struts up front and a multi-link rear-end arrangement.

Aided by an active variable exhaust note (which is quite nicely applied), the 2.0-litre four-pot twin-scroll turbo has a deep set of lungs, providing a decent wad of torque as it revs out fast and freely to its 6000rpm red-line. As you might expect, this is deceptively rapid.

Whether driving the solid and well-oiled six-speed manual – surely one of the best in the business and truly a great thing – or super-slick eight-speed DCT, there’s a delightful amount of muscle and speed for the money.

We’re also fans of the steering’s poise and response, resulting in hunkered-down handling that belies this car’s substantial length and width, backed up by lots of feel and feedback.

Throw in delightfully strong and effective braking, and the i30 N is incredibly alert and agile for something so big.

The trade-off of all this athleticism is a consistently firm – though not harsh – ride, as well as some road and tyre-noise intrusion when cruising comfortably along the highway.

As an everyday commuting proposition, the i30 Sedan N is right on the money.

Out on the racetrack, however, it's like on something a little bit more illicit, for things really start coming alive, with the N’s polished chassis set up revealing a satisfyingly vivid bandwidth of capability.

In 'Normal' mode, the front end feels reassuringly planted with minimal understeer, while the rear possesses a playful lightness that allows for progressive back-end lift-off if desired.

The i30 is so exquisitely tuned and pliable it makes amateurs feel like professionals.

Select 'N' mode and the electronic limiters loosen, for proper oversteer fun if that’s your thing, controlled and reeled right back in by meaty, confidence-boosting steering, providing improbably fluent handling for a sedan this size.

Slicing through tight bends and long arcs alike, the Hyundai’s sheer dynamic precision, consistency and discipline are deeply impressive. And intoxicating. We didn’t want to stop.

It may not look like a hot hatch in the prime of its life, but the i30 Sedan N sure behaves like one. And all for just $52K. Cheers, Hyundai!

As with all i30 Sedans, the N does not score an ANCAP rating because it's not available in Europe. The hatch, on the other hand, managed a maximum five stars back in 2017.

Hyundai is pretty confident the sedan would score highly, too, due to a raft of standard driver-assist safety items, including Hyundai’s 'Forward Collision Avoidance Assist' (version 1.5) featuring AEB with pedestrian and cyclist detection, blind-spot monitoring, safe-exit warning and rear cross-traffic alert.

There is no speed operation data for the AEB and lane-assistance systems at this time.

As well, the N owner also scores driver-attention warning, intelligent speed limit assist, adaptive cruise control with full stop/go, rear occupant alert, six airbags, electronic stability control, anti-lock brakes with 'Brake Assist' and electronic brake-force distribution, tyre pressure monitors, rear parking sensors, a rear view camera, dusk-sensing headlights, auto high beams, rain-sensing wipers and front/rear parking sensors.

As with all i30 Sedans, the N’s back seat comes with two ISOFIX points as well as a trio of top tethers for straps.

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.

The i30 Sedan N brings a five-year/unlimited kilometre warranty, as well as one year of roadside assistance.

Service intervals are at 12-months or 10,000km (not at every 15,000km like the regular i30 Sedan), with service pricing published on Hyundai’s website.

Over the first five years, the standard scheduled cost is $1795, or an average of under $360 annually.
