Toyota Prius vs Hyundai Ioniq 5

What's the difference?

The Prius can rest its weary head. The Age of the Hybrid has begun. Even though this iconic eco car might have lost its ultimate purpose to more mainstream models in the last few years, it’s still the best execution of Toyota’s hybrid tech on the market and if you can look past its divisive-as-ever looks, it’s comfortable and practical, too.

The brand’s Australian division promises the Prius will stick around in one form or another, so we’re keen to see what its next iteration will look like. Plug-in? Fully electric? Time will tell.

The Hyundai Ioniq 5 Epiq N-Line AWD leverages an electric powertrain’s best attributes brilliantly well.

It’s ultra smooth and comfortable with ample performance and great dynamics thanks in part to this car’s N Line spec.

Its price tag pits it against formidable competition from the German Big Three, Tesla and others. But it has what it takes in terms of quality and value to fight that battle. It’s an impressive machine.

The Prius is the very visage of economic motoring. Derided by big-engine lovers, and adored by the eco-crowd, the fact that the Prius’s wedge-shaped frame is more about function than form tells you everything you need to know about this car.

It blends with Toyota’s latest design language, the face and bodywork containing some subtle nods to other models that would launch after it, like the Corolla, Camry, and C-HR.

What always surprises me about even this top-spec Prius is its dorky ride height. For a car with such a low drag coefficient, it sits so far off the ground! The 17-inch wheels look almost out of alignment with the body in those wheelarches.

Round the back, the Prius’s integrated spoiler and glasshouse bodywork are as divisive as ever, with more extreme pointed light fittings leaning into the effect created by its boxy, rear three-quarter view and mirroring the shape of the LED headlights at the front.

Of course, this car is less about being looked at as it is about its drag coefficient of 0.24 Cd, which is one of the lowest on any production car.

Inside, things again prove divisive, with a minimalist dash, a swoopy gloss highlight piece that frames the central vents and multimedia screen, and an odd, centrally mounted dash cluster, which is a usability faux pas.

In the case of the I-Tech at least there’s a holographic display which can put up useful information to help prevent your eyes from drifting too far from the road. Still, I can’t help but feel like this whole interior ethos is futuristic for the sake of being futuristic, with a little less thought given to how practical it is, compared to the brand’s other models.

The leather-appointed trim across the wheel and soft plastics in the door and dash-topper are appreciated, and there’s attention to detail in the little ‘Prius’ logos on the vents. However, I found the dull multimedia screen to be susceptible to glare during the day, and the big integrated panel in which it sits is made from a tinny gloss plastic, which will easily to get covered in fingerprints and scratches.

Is this a big hatchback or a mid-size SUV? I’m on team hatchback, while Hyundai defines the Ioniq 5 as an SUV.

But who cares? They’re just words and the fact is even after close to three years in market this five-seater looks fresh and contemporary thanks to its confident, chiselled lines and wide stance.  

For car-spotters the N Line exterior treatment consists of flat aluminium badging, specific bumpers front and rear, with a deeper nose spoiler incorporating larger vents to cool the front brakes.

There’s also body-coloured cladding and side skirts, gloss black mirror caps, unique 20-inch alloy rims and a ‘hidden’ lighting signature across the top of the front bumper.

Inside there are Alcantara- and leather-appointed seats, an N Line-exclusive partially-perforated leather steering wheel, red contrast stitching and accents, and brushed metal covers on the pedals.

Add in the twin 12.3-inch screens display and this understated, super-cool interior comes to life with a sporty twist. 

The Ioniq 5 scores points for a manual dial for audio control and an Ioniq 5 update earlier this year included a row of simple-to-use buttons for the ventilation system and another on the centre console for seat comfort settings and more. A sensible blend of physical and digital controls.

If nothing else, all of the Prius’s edgy design gives it plentiful interior space. Toyota granted this generation of Prius a low seating position and tall roof, which combine with the distant dash elements to make for a spacious cockpit for the front two occupants.

The seat design in the top-spec I-Tech is also cushy, reminiscent of the seats in high-spec Camrys, and I had absolutely no trouble finding a comfortable driving position. If there’s one thing to be said for the annoying, centrally mounted instruments, it’s that you don’t need to consider the position of the wheel interfering with their visibility.

The Prius’s total glasshouse grants superb visibility out the front and sides, with large wing-mirrors, too. The only downside is that integrated spoiler at the back, which makes for a distracting view out the rear mirror that I’m sure any owner will quickly become accustomed to.

Soft trims across the doors and centre console, even in the back seat, make the Prius cabin a comfortable place to be, too.

Ergonomics have not been forgotten, with the multimedia screen and climate unit having useful and easy-to-reach physical dials and toggles for all the key functions. Even changing gear is a breeze in the Prius, with its odd little rosebud-shaped shifter simply a flick of the wrist from where your arm sits.

I do wish Toyota had made better use of the large area under the climate unit, however. The front part of the centre console is exclusively for the wireless-charging bay alone, and the rest of the space is constructed from a smoothly contoured gloss-finish plastic panel. It has looks to match the Prius aesthetic, but it’s no good for storing anything other than a single phone. It would have been better to make a large bay here with a rubberised finish.

Thanks to the lack of a physical handbrake in the centre or any other buttons or functions, there are two large bottle holders with variable edges.

A huge centre-console box and large door bins round out the Prius’s front-seat storage options.

Room in the rear seat is excellent, my 182cm tall frame had stellar amounts of space for my legs and head, as the roofline continues through to that raised rear spoiler. The comfy seat trim continues, although the padding in the base is notably not as good as it is in the front.

There are some useful pockets on the backs of the front seats and a drop-down armrest with cupholders for rear passengers, too.

Finally, the awkward rear of the Prius makes for a fantastic boot capacity, one advantage this car still holds over its hybrid Toyota stablemates. Capacity for the I-Tech is a mid-size-SUV rivalling 502-litres (VDA), which easily consumed our CarsGuide test luggage set and is even bigger than the base Prius, at the cost of the space-saver spare wheel. The I-Tech only has a repair kit to go with its larger alloys.

At just over 4.6m long, a little under 1.9m wide and a fraction more than 1.6m tall the Ioniq 5 comfortably fits the medium SUV profile.

But arguably its most significant dimension is a 3.0m wheelbase which is huge for a car of this size as evidenced by the wheels pushed out to the corners.

What that means is plenty of space inside, but before you can even get in the capacitive touch power door handles may look cool and help aero performance with their flush fit design but I’m not a fan. They’re hard to grip most of the time and don’t work well from an ergonomic point-of-view.

That said, once inside the front seats are adjustable six ways to Sunday and at 183cm tall I have plenty of head space and breathing room in general.

In terms of storage there are big pockets in the doors with room for bottles and thanks to the ‘shift-by-wire’ gear controller located on the steering column there’s room between the seats for a substantial console including a pair of cupholders, a slot for devices and a lidded tray (which doubles as a centre armrest) with that whole rear section able to swing up to allow access to a large lower shelf underneath.

In fact, the entire console unit easily slides fore and aft to liberate more legroom for the centre rear position. There’s also an oddments cubby in the lower part of the dash and a decent glove box.

Then, for connectivity and power there are three USB-C sockets (one in the dash switchable to streaming), a wireless device charging pad and a 12-volt outlet.

In the back that long wheelbase comes into its own. Sitting behind the driver’s seat set for my position I have loads of foot, leg and headroom.

Storage runs to door pockets with room for bottles, a fold-down centre armrest with a pair of cupholders, there are netted map pockets on the front seat backs and pull-up sun shades on the rear windows.

There are controls for the front passenger seat on the inner edge of the front passenger seat backrest which allows rear seaters to adjust its position. Thoughtful.

For power there’s a pair of USB-C sockets and individual ventilation controls in the back of the B-pillars is welcome. 

Then, not only is the electrically-adjustable rear seat split 60/40 in the backrest, it’s in the cushion, as well, which adds extra flexibility in terms of a balance between rear passenger space and room in the boot.

The boot is generous at 527 litres (VDA) with the rear seat upright and 1587L when it’s folded down.

There’s also a handy 24L ‘frunk’ under the bonnet, a decent portion of which is devoted to the (included) charging cable.

Interestingly, the Ioniq 5 AWD is rated to tow a 1600kg braked trailer with a trailer pre-wiring package standard. 

There’s a repair/inflator rather than a spare tyre, which is never a good thing, but there is a ‘smart’ power tailgate and a ‘Vehicle-to-Load’ function that allows you to power and/or charge three-pin appliances from the car. Handy.

It shows how far the Hyundai brand has come over its close to 40 years in the Australian new-car market that one of its five-seat SUVs wearing a price tag in excess of $90K doesn’t knock the Earth off its axis.

But a sticker price of $91,300, before on-road costs, does apply the pressure because it puts this primo Ioniq 5 Epiq N Line AWD in the same orbit as versions of the Audi Q4 e-tron, BMW iX3, Mercedes-Benz EQB, Tesla Model Y and Volvo’s XC40 Recharge.

In fact, our test car’s price includes the N Line Pack which is technically a $2500 option and its digital mirrors add a further $3000 for an as-tested price of $94,300, before on-road costs.

So, you should rightfully expect a handsome standard equipment list and this full-fat Ioniq 5 doesn’t disappoint.

Aside from the safety and performance tech we’ll get to shortly this car includes 20-inch alloy rims, all LED exterior lights (with auto LED projection headlights), dual-zone climate control, power driver and front passenger seats (heated/ventilated), heated rear seats, ambient lighting, a head-up display, wireless Android Auto and Apple CarPlay, Bose eight-speaker audio, digital radio, built-in nav and voice control for key functions.

There’s also Alcantara- and leather-appointed seat trim, BlueLink connected car services (with a five-year complimentary subscription), configurable ambient lighting, wireless device charging, a fixed glass roof, a heated steering wheel, heated and power-folding exterior mirrors, auto rain-sensing wipers, keyless entry and start, and ‘Remote Smart Parking Assist’.

That last one allows you to start and move the car forwards and backwards remotely (via the key) to insert it into or extract it from tight parking spots… or just impress your friends.

Suffice it to say the Ioniq 5 Epic N Line AWD stands up well against its competitors when it comes to included features for the money.

It wouldn’t be a Prius without Toyota’s signature hybrid synergy drive technology. In this most original case it consists of a 1.8-litre four-cylinder petrol engine, which uses the more thermally efficient but less powerful Atkinson combustion cycle, producing 72kW/142Nm, paired to a set of electric motors on the front axle, which can produce up to 53kW/163Nm.

Combined system output is rated by Toyota at 90kW, driving the front wheels only via a continuously variable automatic transmission (CVT). This system is the same one now also employed in the C-HR and Corolla hybrid grades.

The Prius’s electric motors source their power from an older design nickel-metal hydride battery (instead of the more modern lithium-ion setup) located under the boot floor.

The Ioniq 5 Epiq AWD is powered by a permanent magnet synchronous electric motor on each axle, both powerful, but the rear unit packs a bigger punch.

And combined peak outputs of 239kW and 605Nm are substantial with especially the latter delivering eye-widening acceleration.

Drive goes to all four wheels via a single-speed, reduction gear auto transmission on both axles. And a ‘Disconnector Actuator System’ is able to disengage the front wheels to reduce drag losses from the front motor and improve energy efficiency.

The Prius’ sandpapered hybrid drive, low drag number, weight reductions, and low-rolling-resistance tyres add up for a stellar official/combined fuel-consumption figure of just 3.4L/100km. While its signature hybrid tech might be available on other Toyota’s, it’s here where the Prius still shines, undercutting the others by almost a whole litre every 100km.

But can it live up to that promise in the real world? Over my week of what I would consider to be reasonable ‘combined’ driving conditions; with plenty of traffic, freeways, and suburban driving, the Prius returned a stellar figure of just 4.0L/100km. This is not just one of the lowest figures I have ever achieved on a test car, it is even lower than the Corolla Hybrid that I tested over a three-month period. I couldn’t get that car below 4.9L/100km, despite by best attempts.

For a true rival comparison, my week-long test of the Ioniq hybrid in 2019 had the Korean managing a fuel number of 4.6L/100km.

You need not worry about kWh energy consumption for the Prius, as its hybrid system’s software manages the state of battery charge on the fly. It will simply run the engine to charge the battery if levels drop too low, although it always feels good to make the most of the motor’s regenerative braking to keep the battery topped up.

It’s clear that the Prius is still the king of hybrid, then. At least for the time being. All Prius models have 43-litre fuel capacities and are able to consume base-grade 91RON unleaded.

The Ioniq 5 Epiq AWD is powered by an 84kWh liquid-cooled lithium-ion battery, borrowed from the high-performance Ioniq 5 N.

Thanks to 800-volt compatibility it can accept a 350kW DC charge which translates to an up to 80 per cent charge time of around 18 minutes, which expands to just over an hour using a more typical 50kW charger.

Connect to AC at the Ioniq 5’s maximum 10.5kW capacity and quoted charge time is just over six hours.

Official energy consumption on the combined (urban/extra-urban) cycle is 19kWh/100km and claimed range is a useful 495km.

Over a mix of urban, suburban and freeway running on test we saw a real-world average of 16.8kWh/100km, which is impressive for a car with this much performance potential.

The Prius was responsible for popularising Toyota’s Hybrid Synergy Drive, and fittingly, it still feels like the best execution of the technology on the market. That instantly available torque from the electric motor is sleek, quiet, and easy. It feels as though the Prius can make more extended use of purely electric drive than not only its rivals, but all other Toyota and Lexus hybrid products.

Despite its awkward exterior looks, the ride and handling of the Prius are excellent, thanks to its robust TNGA-C underpinnings (in fact, the Prius was the car to debut this platform for Toyota). It tilts into corners nicely, despite a frumpy ride height, and deals with bumps in its stride. This is a comfortable car, and the Lexus influence here is undeniable. The steering characteristics are also smooth and responsive. I wouldn’t go so far as to say the Prius is fun to drive, but it is certainly comfortable and compliant.

What the Prius lacks is the lower, firmer, and more aggressive ride and handling characteristics of its Hyundai Ioniq rival, perhaps a telling insight into the trajectory of each brand.

These characteristics add up to an around-town driving experience that really is a breeze. It’s quiet in the cabin and at times genuinely hard to tell whether the car is using its electric motors or the engine. When it comes to bursts of acceleration, the Prius might surprise you. Using both the motor and engine in tandem, I found that the Prius can sprint from the line with an alarming urgency, more so than its Corolla sibling. With the same tech behind the accelerator pedal, it’s hard to imagine why.

Once the electric motor has reached its strictly defined limit, though, the engine breaks in with a vengeance, and this car does have an anaemic follow-through when the electric components fall to the wayside. As in other applications of this drivetrain, the 1.8-litre Atkinson-cycle petrol engine can be thrashy and noisy when a lot is asked of it.

Of course, driving in such a sporty manner is hardly the point of the Prius, and where it really excels is in that day-to-day traffic grind, where the hybrid system works largely in the background to maximise the time spent with the engine off. The best part? While you can really fall into the hybrid system’s addictive fuel-saving displays, which really encourage hypermiling, this is a set-and-forget system. You can drive the Prius like any other car, and it will be trim on fuel consumption anyway. It’s not like I was trying awfully hard to attain my weekly figure of 4.0L/100km, so I’m sure it can do better over the long term.

In terms of straight line performance we’re talking 0-100km/h in a tick over 5.0 seconds and I see anything in the five-second bracket as properly quick.

With more than 600Nm of peak pulling power at your disposal there’s always plenty of pulling power for efficient in-traffic moves and safe highway overtaking.

The shift-by-wire gear selector on the steering column takes some getting used to but once you’re in tune with it, it’s surprisingly convenient, especially during slow speed parking or turning manoeuvres. 

There are multiple modes - ‘Eco’, ‘Normal’, ‘Sport’ and ‘Snow’. Sport mode spices things up a bit with more urgent responses and the ‘HTrac’ AWD system uses multiple sensors to manage potential wheelspin and optimise drive in wet conditions or on loose dirt surfaces.

Suspension is by struts at the front and multi-links and the rear and the Ioniq 5 in this configuration is ultra-smooth and comfortable.

Even hitting pretty aggressive speed bumps and ruts in the road and the car soaks them up without fuss. You’re used to EVs being a little harsh in terms of ride compliance thanks to their relative weight, but that’s not the case here.

As part of a model upgrade introduced earlier this year Hyundai says it undertook a “comprehensive revision to the suspension tune”, which includes high-performance dampers on this N Line. And despite low-ish profile (255/45) Michelin Pilot Sport EV tyres on the 20-inch rims it remains comfortable and quiet.

The upgrade also included body reinforcements in the B- and C-pillar, door surrounds and under the body for a stiffer platform overall.

That pays off in the dynamics. Despite its 2.1-tonne weight the Ioniq 5’s steering is accurate and nicely weighted. It doesn’t feel lumbering or ponderous despite its relative heft.

The physical brakes are ventilated discs front and rear with regenerative available through four levels, the most aggressive setting being ‘i-Pedal’ which allows single-pedal driving.

It will slow the car to a full stop, harvesting the most energy possible in the process, although you might need a dab on the brake pedal if things are tight.

Miscellaneous observations include a 12m turning circle, so be ready for three-point turns where you didn’t think you’d have to.

Hyundai's (and Kia’s) default over-speed warning is present in full-force taking clicks through multiple screens to switch off and avoid its incessant audible alarm saying you've exceed what the car believes is the posted limit (every time you restart the car).

The recently released Tucson Hybrid features a short-cut function to do away with this issue and it would be welcome here.

The CPU underpinning the multimedia system is more powerful and response is speedy without a hint of lag.

And the camera based ‘mirrors’ take some getting used to. For many, they’re the answer to a question no one was asking. I mean, conventional mirrors work pretty well and any aero benefit from the smaller camera units has to be modest. But once you’re in tune with them the hi-def screens are excellent.

A flip of the switch on the interior rear view mirror allows you to side-step tall heads or loads in the back of the car but minimal depth of field is also (visually) awkward at first.

The Ioniq 5 received a maximum five-star ANCAP score from assessment in 2021, receiving its highest scores for adult and child occupant protection and the on-board safety assist systems.

The Ioniq 5 stacks up well relative to its competitors when it comes to safety. In fact, there’s so much crash avoidance tech on-board, courtesy of the Hyundai ‘SmartSense’ active safety suite, it would be straight up boring to list it all, but the highlights include AEB (with car-to-car, pedestrian and cyclist detection as well as junction turning and crossing functions), blind-spot monitoring and collision avoidance, lane keeping assist and lane departure warning, rear cross-traffic alert and rear AEB as well as active cruise control (with stop and go).

There are even more assists, warnings, monitors and alerts, but it’s important to note they (almost) all operate with relative subtlety. I did switch off the steering assist/lane-keeping functionality when it became confused and overly intrusive on twisting city curves.

If a crash is unavoidable, there are seven airbags on-board including a front centre bag to minimise head clash injuries in a side-on impact, as well as ‘Automatic Collision Notification’ and an emergency SOS call function operated through the Bluelink system.

For baby capsules/child seats there are three top tether points across the second row with ISOFIX anchors in the outer positions.

Toyota’s range-wide warranty currently stands at five years or unlimited kilometres, which is really the accepted industry standard and matches its key Ioniq rival.

Annoyingly, however, the Prius needs to adhere to six-monthly or 10,000km service intervals. Said intervals are capped to $165 per visit for the first six visits under Toyota’s “service advantage” program, after which time you fall back to Toyota genuine servicing with significant price hikes to $221.97, and $425.47 for the next two services covering four years or 80,000km.

A year of roadside assist is included, after which time you will need to subscribe to Toyota’s program, from $89 a year.

While Toyota’s offering is on par with many, it’s hardly the cheapest or most comprehensive we’ve seen.

Hyundai covers the Ioniq 5 with a five-year/unlimited-km warranty, which is the mainstream market norm, with a separate eight-year/160,000km warranty for the drive battery; also an expected term.

Roadside assistance and sat-nav updates are renewed annually if the vehicle is serviced at an authorised Hyundai dealer.

Service interval is two years/30,000km which is appropriate for an EV given its relative mechanical simplicity and a ‘Lifetime Service Plan’ locks in scheduled maintenance costs for the life of the vehicle.

Service cost for the first five years is $1220, with each of the two services required in that time coming in at $610. Competitive for an EV in this part of the market.
