Hyundai Accent vs Kia Optima

What's the difference?

It might be getting harder and harder to hide its age, but there is still plenty to like about Hyundai's cheapest car. Those who really love to drive need not apply, and nor should long-distance travellers, but the Accent Sport's alloy wheels, true smartphone integration and plenty of power and USB points will thrill its younger owners, while its long-range warranty and cheap servicing costs don't hurt either.

Still, if you think you can stretch to an i30, you should definitely drive one first.

If you travel long distances, want a good amount of space and don’t want to pay big bucks for a new car, then yeah, maybe there is a reason sedans like this will hang around for a while longer.

Sure, the appeal of sedans mightn’t be as strong as it once was, but models like the Kia Optima prove they still have a reason to exist.

It looks good, the Accent, just not quite as good as its bigger Hyundai brothers. And that’s got to sting, if only a little bit. 

Words like "subtle", "restyled” and “enhanced design” pepper the Accent’s media information, and so we’re not talking massive changes. But the exterior of the Sport looks sharp, especially in the 'Pulse Red' of our test car. Other colours include 'Chalk White', 'Lake Silver', 'Phantom Black', 'Sunflower' (yellow), and 'Blue Lagoon', but there’s no green, orange or grey paint available.

First, though, don’t let the whole 'sport' thing fool you. You’ll find no Fast and Furious body kit, nor is there much in terms of a rear spoiler, side skirts or a rear diffuser. Instead, a silver-framed mesh grille (a smaller version of the one that adorns the i30) blends into the headlights that then sweep back into the body, while subtle power lines create a little dome in the bonnet, starting at the edges of the Hyundai badge and getting wider as they sweep back across the bonnet. 

Side on, the alloys are clean and simple, and a single style crease runs the length of the body, intersecting both door handles on each side. At the rear, though, the concave body styling doesn’t quite work so well, ending up looking busier than the rest of the car, and leaving it with too much body and not enough rear window.

Inside, as you can see from our interior photos, there is plenty of hard plastic, but there have been some design flourishes that give them a nicer texture and go some way to disguising the fact they’re hard enough to be used as a weapon in a roadside road rage dispute.

But it’s a simple and clean design, with patterned cloth (what, you were expecting leather seats at this price point?) seats, an uncluttered centre cluster and a sparing use of silver highlights that break up the black of the dash and doors.

You can also option everything from tailored floor mats to interior lighting, forming a kind of personalised premium package for the Accent Sport.

Cosmetic changes for the facelifted 2018 Kia Optima include new headlights and tail-lights with revised LED signatures (but still halogen lamps in the base model), and there are newly sculpted bumpers and new wheel designs across the two-model range. 

We had the base model Si, which doesn’t look as good as the GT model, because it has smaller wheels, the sporty body kit and misses out on the LED headlights, but the LED daytime running lights are still present.

The GT has a more aggressive look, and the side skirts, front spoiler and rear diffuser fit it better - there are dual exhausts, but not sporty quad exhaust tips.

In fact, this model is a bit like the old-man version of the Optima. No offence intended to old men, of course. The GT is just heaps sportier, and I reckon it’s considerably more attractive as a result. 

Still, the inherent sleek styling of the Optima remains - the chrome highlighting along the window line is a bit too sheeny for me, but the angles and stance of this model are quite gracious. I really dig the fact the top of the windscreen mirrors the ‘Tiger Nose’ grille shape.

I'm no exterior designer, but I liked the existing Optima more - it just looked a bit neater, even though it had a decent amount of bling with its Mercedes-like diamond-pattern grille, as opposed to the cheese grater look seen here.

There’s not quite as much bling inside the cabin of the Si, either, but it is still a well-designed space - just not as special as the premium package offering of the GT (which gets leather trim - not nappa leather, but still a quality cowhide finish, and more). Check out our interior photos to see if you agree - but size and interior dimensions of the Optima are hard to argue against.

It’s every bit as practical as you might expect, the Accent Sport, given that you’re unlikely to be using something this size as a pseudo moving van anytime soon.

The 4155mm long, 1700mm wide and 1450mm high (the sedan is 4370mm long) Accent Sport's interior dimensions feel spacious up front, and while the front seats are a little too flat, the cabin feels airy and light. There are two cupholders up front, too, and there’s room in the front doors for extra bottles. 

Like all Hyundais, the little Accent boasts most of the technology options favoured by younger buyers, like a USB point, an aux connection and two 12-volt power outlets all housed in a tiny storage bin underneath the centre console. There’s a sunglass holder, too, integrated into the roof. 

The backseat is sparse but spacious enough, with enough room for adults to sit behind adults in comfort - at least in the two window seats. That’s about it back there, though, with no technology options, vents or air-con controls.

Boot space is a useable 370 litres in hatch guise, but luggage capacity grows to 465 litres should you opt for the sedan, with both of those figures measured in VDA. Optional roof racks and rails (and other offical accessories like a rubber cargo liner, mud flaps or dedicated bike, snowboard and surfboard carriers) help increase the pint-size Accent’s load-lugging ability.

As does a handy (and optional) cargo liner that helps separate your groceries, sitting neatly under the cargo cover that shields you luggage from prying eyes outside. Perhaps unsurprisingly, you can’t get a factory-offered bull bar.

There are two ISOFIX attachment points, one in each window seat, as well as three top-tether points across the back row.

I really like the way Kia designs its cabins. Sure, there’s a lot of black in here, but there’s also a lot of thought put into the usability of the space.  

The high-mounted 7.0-inch infotainment and multimedia touch screen in the Si is simple to use, and for 2018 the Optima range gets Apple CarPlay and Android Auto - you couldn’t get that in the Optima up to this point. 

Also included are a reversing camera, USB input, Bluetooth phone and audio streaming and six speakers. The Si model misses out on sat nav - you’ll have to use the maps app on your phone. No DVD player either.

Storage is well thought out in here, with big bottle holders in the doors, a good sized pair of cup holders up front, and a nice little storage bin for your phone, wallet, keys and so on.

There’s a driver info screen with a digital speedo, and even on this base model you get a dual-zone climate control air conditioner. The updated Optima gets a new steering wheel, too.

Now, what about the back seat?

It may be considered a ‘mid-sized’ sedan, but there’s limo-like space. With the driver’s seat in my position (I’m about six feet tall) there was still heaps of rear legroom in the rear seat, with ample knee room, good foot room and decent shoulder space, too - three of me could slot across the back bench comfortably, which means kids will fit easily, too. There are three top-tether points and two ISOFIX points as well.

Kids and adults alike will be happy with the rear air vents back here, and there’s a flip down armrest with cupholders, too. Again, big bottle holders appear in the doors, and there are map pockets in the back seats.

What about boot space? With so many people choosing SUVs over sedans because they’re theoretically more practical, the Optima offers good food for thought - it has enough luggage capacity for a bunch of suitcases (510 litres VDA in size) and there’s a full-size alloy spare under the boot floor. If you need more, you could always invest in a roof rack setup?

Kia dropped prices for this updated and facelifted model range - and not by a small amount, either. So, what's the price? How much does it cost?

The Si model is the entry-grade of two models, and it comes in at the bottom of the price list at $33,290 plus on-road costs (rrp) - an $1100 drop over the previous version. The Si, then, is a value-focused sedan that you might consider if you’ve looked at a Toyota Camry Ascent, Hyundai Sonata Active, Mazda6 Sport or Subaru Liberty 2.5i.

The standard equipment list is pretty good - although there have been some deletions, because the price is down $1100. The rather good HID headlamps with washers have been dumped in favour of halogen projector lights (yeah, not even xenons), and the satellite navigation system (GPS) is gone.

But now the 7.0-inch media screen is capable of doing the Apple CarPlay iPhone connectivity and Android Auto phone mirroring thing, and that’ll serve most people’s purposes pretty well, but there is no digital DAB radio, and no CD player for the sound system. Other standard kit includes a digital driver info display with digital speedo, dual-zone climate control, cloth seat trim, auto-dimming rear-view mirror, a reversing camera, front and rear parking sensors, auto headlights and rain sensing wipers, and 17-inch alloy wheels (with a full-size spare). 

New equipment for the Si includes driver-fatigue monitoring and an active lane-keeping assistance system (in place of the old lane-departure-warning buzzer). 

If you want all the fruit you really need to fork out the extra cash for the GT, which lists at $43,290 plus on-roads (vs $33,290 for the Si). That is getting perilously close to Kia Stinger territory… but let's not get too far ahead of ourselves - this isn't a model comparison!

You get a fair bit more for your dough, but even the GT has seen a few deletions to help justify its $1200 price drop compared to the pre-facelift model, such as the front passenger seat being manually operated (previously electric), the cooling/ventilation of the front seats has been deleted, and the panoramic sunroof of the previous model is gone, too. And while it rides on 18-inch rims with a new design, the tyre-pressure-monitoring system has been removed.

It uses a new 8.0-inch media screen with extended smartphone connectivity and in-built sat nav (with 10 years of maps included and SUNA live traffic updates), and it also gains redesigned LED headlights but they lose the smart auto high-beam assistance of the old model. The tech doesn't go as far as to include Homelink garage door opening here in Australia, either.

Other standard kit in the GT includes leather seats, electric driver’s seat adjustment with memory settings, smart key (keyless entry) and push button start, a sports body kit, a harman/kardon audio system with 10 speakers and a subwoofer, wireless phone charging (Qi) but no Wi-Fi hotspot, rear sunshades (but no tinted windows), different interior trim finishes, a heated steering wheel, and a colour driver-information screen. 

The GT also gets the new lane assist system and driver-fatigue monitor, and the entire safety approach has been improved across the range. See the safety section below for more detail. 

There is no launch edition, nor is there a sports edition, but there is a decent array of colours (or colors, depending on where you're reading this) available - black, white, blue, red, grey and silver can be chosen, but not brown, purple or gold... if you wanted those. 

Accessories available across both trim levels include tailored floor mats, a dash mat and weathershields, among other items. 

The one Accent on offer is powered by a single engine; a petrol-sipping (there’s no diesel, LPG or turbo), 1.6-litre motor that will produce a solid-sounding 103kW (138 horsepower) at 6300rpm and 167Nm of torque at 4850rpm. They are good specs, and it stands up to most competitors in an engine vs engine models comparison. It pairs with a choice of six-speed manual transmission or six-speed automatic transmission.

There used to be a fairly underwhelming 1.4-litre engine size paired with a CVT auto in the now-axed Accent variant, but this bigger engine is much, much better, and makes for much happier reading on the specifications sheet.

The Accent is front-wheel drive only, with no 4x4, AWD or rear-wheel drive options available. It will serve up a 900kg braked and 450kg unbraked towing capacity, with an optional tow bar/ball fitted. Kerb weight is listed as between 1070kg and 1170kg.

The Accent Sport uses MacPherson strut front and torsion beam rear suspension (no sophisticated air systems on offer), and Hyundai doesn’t quote any 0-100km/h, acceleration or speed figures.

The Si model is powered by a 2.4-litre four-cylinder petrol engine, which has seen no changes to its specifications for this mid-life update.

Engine specs remain at 138kW of power at 6000rpm, while torque is rated at 241Nm at 4000rpm. It makes use of a six-speed automatic transmission only - there’s no manual transmission here, but you do get paddle shifters - and it's front wheel drive (the Optima isn't available with AWD, or as a 4x4, or in rear wheel drive - the latter is left to its bigger brother, the Stinger).

The GT gets a zestier drivetrain with more horsepower - it has a 2.0-litre turbo four-cylinder engine with 180kW/350Nm, which is much more desirable, but also louder than the Si’s 2.4. It also has a six-speed auto transmission, and is FWD. If you're into ratings and statistics, that 2.0-litre with a turbocharger is one of the perkier offerings for its engine size in the class.

There is no hybrid model available, despite a plug in hybrid petrol version (allowing you to run in EV mode) being sold in European markets. No diesel here, either, while other markets get a 1.7-litre turbo diesel. No LPG model here, or anywhere else, for that matter.

Towing capacity for Optima models is 750kg unbraked and 1700kg braked for the 2.4-litre, and 700kg/1400kg for the 2.0-litre turbo. Tow bar down-weight is capped at 80kg.

For fuel consumption, Hyundai claims 6.3 litres (6.6 litres for the sedan) per hundred kilometres on the combined cycle. But as with all of these manufacturer-supplied figures, there’s always a some sort of variation in the real world km/l fuel economy.

Just how much variation is dependent on how heavy your right foot is, but after my (admittedly city-based) week with the car, the trip computer had my mileage at 11.0L/100km. If you were to adopt an eco mode driving style, that would surely improve, though.

The Accent’s fuel tank size is fairly small, with a fuel capacity of just 43 litres - perfect for the city, less so for long-distance cruising. Emissions are a claimed 146g (154g in the hatch) per kilometre of C02. 

Kia claims a very realistic fuel economy rating of 8.3 litres per 100 kilometres for the Si model, and we saw damn close to that consumption during our week of testing. On the highway it will sit at around 6.5L/100km, ensuring good mileage, while city driving will push usage above 12.0L/100km. Our overall average was 8.5L/100km, which is good. Use the eco mode, and you'll get a little better use.

The turbocharged GT model uses a little more, according to Kia’s 8.5L/100km combined average claim, but we guarantee you’ll actually use more than that because it’s more eager to please.

Fuel tank capacity is 70 litres - plenty of size for long distance drives.

With its sharp design and gleaming alloys, the Accent Sport doesn’t look like an entry-level model, and nor is it immediately obvious that it’s the cheapest way into the Hyundai family. The downside, though, is it does feel that way from behind the wheel.

A little harsher, a little more road noise and a little more gruff than Hyundai’s more expensive models (including the very good i30), it’s the unfair victim of the brand’s staggering success, which has left the Accent feeling a bit old-school by comparison.

That said, it's perfectly suited to inner-city life, and if you’re cruising around using minimal inputs, it does it all smoothly and quietly. The steering feels a little slack at slow speeds, with plenty of dead air when you first start turning the wheel, but none of that bothers you much in the city.

With its sharp design and gleaming alloys, the Accent Sport doesn’t look like an entry-level model.

The grunt from that engine is refreshingly ample for a small car, and provides plenty of punch to get you moving from traffic lights, while the seating position is high enough that vision is great out of every window (except the rear - you’ll be using the reversing camera for that one).

Take it out of town, though, and the refinement begins to vanish. The engine sounds harsh under heavy acceleration, the transmission can be confused - especially around 80km/h, where moving your foot a fraction can force continual changes up or down, like it's wrestling with a big life decision. 

The only other question mark is over the suspension set-up, which for some reason favours sporty firmness in a car unlikely to be asked to achieve anything more dynamic than sitting at 50km/h. The result is a ride that can feel noticeably firm over bad road surfaces.

The Accent’s 140mm ground clearance (not to mention the fact it’s a front-wheel drive city car) should be enough to persuade you not to test its off-road performance. And its turning radius is 10.4m.

The Optima has some really good elements to the way it drives, but sadly  some less impressive bits as well.

Let’s start with the not-so-great stuff - the 2.4-litre engine in this Si model just isn’t as enjoyable as the turbo unit, and the fact that Kia still doesn’t offer a hybrid version here, despite doing so elsewhere, is a bit of a downer.

The drivetrain isn’t terrible - the six-speed auto is smart enough, and there’s usable power if you boot it. The two more sedate drive modes, 'Eco' and 'Comfort', mean the transmission will aim to save fuel and limit throttle response, with a bit more of a lazy feel to the drive experience. But in 'Sport' mode it is definitely more rewarding in terms of acceleration and performance, offering a bit more pep and urgency (we didn't do a 0-100 km/h speed test, but take our word for it); it undoubtedly at the cost of fuel consumption.

It’s just a bit of a shame Kia doesn’t offer the turbo in this spec, too. Fuel use for the Si model is better than the turbo, however, so it could be ideal for buyers who are more worried about the bottom line than design and a sportier drive.

The thing I like most about the Optima is its road manners - the steering and suspension have been tuned for local conditions, just like all Kia products, and it shows. 

The electric power steering is really well sorted, making for easy parking moves and good assuredness at higher speeds. And the turning circle is decent, too - 10.9m (so, the turning radius is 5.45m). 

Plus the ride comfort is really good. On the highway it coasts along with very little fuss, and around town it deals with lumps and bumps impressively. Sharp edges can upset things a tad, and mid-corner bumps can make it jitterbug a little bit, but not to a degree that would rule it out of contention if you want a mid-sized sedan.

It’s pretty quiet on the open road, too, and the adaptive cruise control makes long-distance driving a simple task. The GT does suffer a little bit more road noise, though.

The safety rating of the Optima remains at five stars, as it was when the car was tested in this generation in 2015.

The updated Optima carries over the safety features of the previous model including autonomous emergency braking and adaptive cruise control, while the lane-departure warning system is now supplemented with lane-keeping assistance, and there’s driver-fatigue monitoring added, too. There is no park assist / self parking system.

That’s in addition to a reverse camera, front and rear parking sensors, and all the systems you’d expect, like stability control, anti-lock brakes, hill-start assist and seatbelt reminders.

Airbag coverage for Optima models is six: dual front, front side and full-length curtain. And parents will be happy to learn there are three top-tether attachment points, and two ISOFIX anchors, too. 

If you've been wondering to yourself, "where is the Kia Optima built?"The answer is South Korea. 

It’s a very strong ownership picture, with the Accent Sport covered by Hyundai’s five-year/unlimited-kilometre warranty, and requiring a trip to the service centre every 12 months or 15,000km.

A capped-price servicing plan helps take the guesswork out of your service cost, too, with guide prices at between $245 and $345 per year for the first five years.

For known Hyundai Accent issues and common problems, complaints and faults - including any known clutch, suspension, gearbox, engine, battery or automatic transmission problems - head to CarsGuide's dedicated Hyundai Problems page. 

One of the most common mechanical questions asked is whether the Accent uses a timing belt or chain, and the Sport uses a timing belt. Check your owners manual for recommended durations between changing  it.

Hyundais traditionally score very well in international reliability rating surveys, which helps protect its second-hand ratings.

Kia remains a shining light in terms of its new-car-ownership promise, with a very strong seven-year/unlimited kilometre warranty. It makes a lot of sense if you plan to hang onto the car for a while. There's no extended warranty available, which is understandable.

That plan also includes a roadside-assist plan for the same seven-year period, provided you maintain your car with Kia Australia. So, given you get one year to start with, then you get an extra year of cover every time you go back to Kia to get your car serviced, you could end up with eight years of coverage. Nice!

Servicing is due every 12 months or 15,000km, with the first seven years covered by a capped-price-service cost / maintenance cost plan. The costs are: service one - $289; two - $466; three - $360; four - $559; five - $325; six - $599; seven - $345. That makes a total cost of $2943, which is competitive for its class. Keep your owners manual or logbook up to date, and your resale value should hold up better.
