Hyundai I40 vs Hyundai Sonata

What's the difference?

The i40 Tourer in the Active grade is great to drive, it’s practical, and should be low-cost to run. But you can bet the new version, due to arrive soon, will be, too. If you can wait, it's a safe bet the new i40 Tourer will have an updated look, improved safety equipment and retain all the good points of the previous model. 

The updated Sonata N Line looks beautifully modern from its new face to the refreshed cockpit, while remaining a ‘driver’s car’ with good dynamics, and a sporty engine. 

The Sonata isn’t an ideal family car, however. This is down to a lack of practicality. Although the cabin is fairly roomy, if that roofline wasn’t so coupe-like and cabin storage was better, and the boot had a large hatch opening, and the ride height was more elevated then it would be a great family car. Oh, I’ve just described an SUV.

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

The i40 wagon looks good, I even caught myself doing that admiring 'look back' thing you do when you walk away from your car. Thing is, the current i40 has the ‘old’ Hyundai styling that dates it compared to the new i30, Sonata and Kona, which reflect the brand’s latest look.

This brings me to something you should really know – the newer, updated i40 will arrive in Australia soon, and it will be more in line with Hyundai’s current design approach.

The i40 is also up against some hot-looking rivals. The Mondeo is gorgeous, the Passat is stately, and the Commodore also looks stunning. To be honest the i40 is the least attractive of that lot form where I’m looking. It’s also about the same size as that trio at 4775mm long, 1815mm wide and 1470mm in height.

My mum would call the interior of the i40 Active smart looking, but she doesn’t mean tech-smart, more school dance smart, and if she ever said that before you went to a school dance you’d get changed immediately.

Yes, it looks smart in a tidy, stylish way, but that tiny screen, cloth seats and ordinary plastics lower the tone compared to the Premium's more 'premium' interior. 

So, we’ve established that the Sonata N Line is a sedan and that means if you’re still reading this you are, a) A Sonata owner looking to trade the old one in for this new one, b) Driving another type of sedan such as a Toyota Camry or Volkswagen Passat and looking to update your trusty steed with one from Hyundai or c) Not in the market for an SUV.

Whatever the reason, sedans lend themselves to being sleek and sophisticated in their styling just by being lower to the ground than SUVs and generally longer than sports cars.

The Sonata N Line is long at 4.91m end-to-end. That’s only 8.0cm shorter than the gigantic Hyundai Palisade which has eight seats. I know… it bends the mind.

This new Sonata N Line looks even wider than the previous version, too, with that broad flat bonnet meeting the Seamless Horizon LED strip.

Fact is the Sonata N Line is 1.86m across - exactly the same as the previous version. Remind me never to wear a 'seamless horizon' T-shirt on days I’m feeling rotund. 

If you look closely at the photos you can see the hidden LED headlights flanking the large, dark and low-set grille.

The rear of the new Sonata looks so different from the previous version, too, with its boot lid spoiler and LED tail-lights. 

The menacing body kit comes with the N Line grade and accentuates the sporty nature of this car. It’s a good thing it has an engine to back up the looks, but more on that later.

Inside, the Sonata has been given the new 12.3-inch curved screens and a digital climate control display, while the steering wheel is new and adorned with the Hyundai 'Morse Code' badge (the letter H is four dots in Morse Code). It’s a premium and modern looking cockpit topped off with suede and leather leather N Line sports seats.

The i40 wagon nails the practicality category. Storage space is excellent with a deep, wide console bin under the centre armrest, and there’s another big well in front of the gear shifter. 

There are large pockets in all the doors with bottle holders, two cupholders up front and another two in the fold-down rear armrest, plus another storage area in there, too.

The i40 Tourer’s 506 litre cargo capacity is good, but can’t beat the Passat’s 650 litres, while it matches the Mazda6 wagon’s boot space.

Rear legroom borders on limo territory and even at 191cm I can sit behind my driving position with about 50mm of space between my knees and the seat back. Headroom back there is also extremely generous.
The rear doors open wide, making for an easy exit or entry, too.

Sedans might be sleek and sophisticated but practicality is not typically their strength because their low height means passenger access isn’t as easy as it is with an SUV, but mainly because the cargo carrying ability is limited by the relatively small boot opening.

Still, the Sonata N Line does have a big 480-litre boot and cabin storage has been improved thanks to the gear shifter being relocated to the steering column and freeing up space in the centre console for stowing items and a wireless phone charger.

Rear legroom is also good. I’m 189cm tall and I can sit behind my driving position with space to spare. Headroom back there is also good thanks to contoured heading which has a ‘carved out’ section for extra space.

Along with the wireless phone charger there are two Type-C USB ports up front and another two for the second row.

There are four cupholders (two up front and two in the second row) and decent sized bottle holders in the doors.

This lack of practicality compared to an SUV or even a station wagon means the Sonata N Line really isn’t the perfect family car.

Hyundai offers one type of Sonata in Australia, so there’s not a lot of choice. Actually there’s no choice: it’s the petrol version of the Sonata in the sporty N Line grade or nothing.

But if I were to choose one Sonata this would be the one, even if at a list price of $55,500 it’s quite expensive and about $3500 more than the previous Sonata N Line.

In return for the almost $56K price you’re getting a lot of standard features, including a mountain of new equipment for this updated model.

So, new for this 2024 Sonata are dual 12.3-inch curved screens for media and driving instruments, the digital climate control display, there’s a column-mounted gear shifter, LED ambient lighting and a hands-free boot lid. That’s in addition to proximity unlocking, sat nav, Apple CarPlay and Android Auto and a 12-speaker Bose sound system.

There’s also suede and Nappa leather seats, a leather steering wheel, sunroof, dual-zone climate control, heated and ventilated front seats, a heated steering wheel, LED headlights and the LED strip which wraps around the front of the Sonata.

Hyundai calls it the 'Seamless Horizon', which sounds beautifully poetic and leads us nicely into the Design section of this review.

This is another area in which our test car impressed with its 1.7-litre four-cylinder turbo-diesel and seven-speed dual clutch auto transmission.

At 104kW, it may be less powerful than the petrol (121kW) but its 340Nm of torque gave it the shove to accelerate impressively from 1750rpm (idle is 800rpm).

The engine and dual-clutch combination performs beautifully; smooth even at low speed in traffic, and shifting down intuitively to make best use of engine braking.

The Sonata N Line comes with a 2.5-litre turbo-petrol four-cylinder engine making 213kW and 422Nm, which is plenty of oomph, and it all goes to the front wheels through an eight-speed dual-clutch automatic transmission.

So no, there’s not a diesel version nor an all-wheel drive version, but this sporty engine suits the Sonata N Line perfectly.

That said a hybrid variant would be good seeing it’s 2023.

Hyundai will tell you the i40 Tourer diesel will get 5.1L/100km over a combination of open and urban roads. The trip computer in our test car said it was averaging 7.4L/100km. Still, that’s not bad mileage.

As we were saying above there’s no hybrid variant of the Sonata N Line and there should be. Actually there is, but Hyundai says it isn't available for the Australian market.

So, this turbo-petrol four-cylinder is all we have and according to Hyundai it uses 8.1L/100km on the combined cycle.

When we tested it at the launch our trip computer was reporting exactly 8.1L/100km, but the roads were clear, the traffic was nowhere to be seen, so you can expect that consumption to climb higher if you’re commuting around the city.

A comfortable ride, impressive handling for the class, and a great engine and transmission mean the i40 Active Tourer diesel is engaging and enjoyable to drive. 

The driving position is excellent, the seats are large but supportive, and the pedal feel is spot on. The i40 Tourer is way better to drive than it needs to be and would embarrass some cars from more prestigious brands.

It’s not all perfect: the cabin could be better insulated with wind noise obvious at 90km/h and tyre rumble intruding on course chip roads; visibility is hampered by those slanted A-pillars and the reversing camera image is next to useless thanks to the business card-sized screen in the Active.

The Sonata N Line’s performance matches its sporty looks. That turbo-petrol engine is responsive and provides great acceleration, the transmission shifts fast and the steering is nicely weighted and accurate. 

Add to this better rigidity in the car’s structure in this updated model and a feeling of stability thanks to this being a sedan with a low centre of mass and you have a dynamic and enjoyable vehicle in your hands.

Sure it doesn't have the sky-high visibility that comes from the pilot’s seat of an SUV, but the Sonata N Line is for those who like to drive but still want the practicality of four doors, back seats and a boot.

The Sonata N Line hasn’t been tested by ANCAP, but it does have an extensive armoury of safety tech including AEB (which also works at intersections) able to detect pedestrians, cyclists, other cars and now motorbikes.

There’s blind spot warning which pulls you back into your lane and lane keeping assistance, plus rear cross-traffic alert with braking, as well.

A rear occupant alert will remind the driver there are passengers in the back seat and 'Safe Exit Assist' will protect children from opening the door into moving traffic.

Along with all this, which Hyundai bundles together in its 'Safety Sense' package as standard on the Sonata N Line, there are also side airbags protecting the rear passengers and plenty of airbags in the front for the driver and passenger.

The i40 Tourer is covered by Hyundai’s five-year/unlimited-kilometre warranty. Servicing is recommended every 15,000km/12months at a capped price of $339. A servicing plan is also available for three years ($777), four years ($1136), and five years ($1395). 

The Sonata N Line is covered by Hyundai’s five-year, unlimited-kilometre warranty. 

Servicing is recommended annually or every 10,000km. There’s no capped price serving but you can buy a 'Lifetime' or a five-year plan that work out to be between $350-$400 on average a year.
