Honda Accord vs Kia Optima

What's the difference?

Will the new Honda Accord e:HEV RS topple the SUV throne? Unlikely, but it proves sedans can still haul the family around in relative comfort and style.

The new Accord drives stupidly well and offers great ongoing ownership costs, even if it's price tag is a little steep. It's hybrid powertrain also offers fantastic efficiency and that's a big win.

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.

The design for the new Accord is powerful with a sexy silhouette that features a rear spoiler, black accents and sporty 18-inch alloy wheels.

The old chunky grille is long gone and at certain angles you almost get a Nissan 200 SX vibe, which is gorgeously retro and a refreshing take for Honda - which has been playing it safe for the last few years.

The interior is simply styled but looks timeless. The dashboard has clean lines and a featured honeycomb mesh that hides the air-vents. It's a feature which might not land with everyone but it adds personality.

The black upholstery looks plush and there are enough soft-touchpoints to make the cabin feel like it deserves a premium tag.

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.

Access to the cabin is great thanks to wide door apertures but the Accord is a low car to get in and out of with its 134mm ground clearance. Expect a couple of grunts when parked on a hill!

Both rows offer ample legroom but the front enjoys the best of the headroom. A 183cm (6.0ft) friend was lumped with the middle seat and spent the trip dreadfully hunched over and uncomfortable. Save the middle seat for kidlets.

The electric front seats offer decent comfort for a longer trip but it's disappointing that only the driver’s side gets lumbar support.  

The rear row enjoys well-padded seats and amenities, like retractable sunblinds, reading lights, two USB-C ports and directional air vents but it took a while for the back to cool down on hot days which my kid made known. Loudly. 

Storage consists of a large glove box and middle console (which can accommodate a small handbag), a sunglasses holder, four cupholders, four drink bottle holders and two map pockets. There is also a dedicated phone tray but a few extra cubbies up front would be welcomed.

The boot offers plenty of space with its 570-litre capacity, which is great for the class, and you can also open up storage options with the ski-port door, if need be. The powered boot release is a handy feature.

The touchscreen multimedia system looks nice but is a pain in the butt to use until you set some time aside to get to know it. It’s just not intuitive but the screen is responsive and it's a bonus that you get the built-in sat nav and Google apps. 

The new Accord gets wired and wireless Apple CarPlay and Android Auto but it took a few beats to get the wireless CarPlay to work.

The charging options are good throughout the car with four USB-C ports, two 12-volt sockets and a wireless charging pad to choose from.

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. 

Our test vehicle has an electric continuously variable transmission and features a new self-charging hybrid powertrain that couples two electric motors with a 2.0L, four-cylinder petrol engine that combine to produce 135kW of power and 335Nm of torque.

Only being available in one powertrain may limit its audience but the combo delivers decent performance for a sedan of this size.

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.

The new hybrid powertrain means lower outputs and the official combined fuel cycle figure is just 4.3L/100km! Which is only beaten by the Toyota Camry's 4.0L/100km.

The on-test figure pops out at 5.1L/100km after doing a some urban stuff but mostly open-road driving. Which is where hybrids tend to be the least efficient, so the fuel usage is excellent.

Based on the official combined (urban/extra-urban) fuel cycle and 48L fuel tank, you should see a theoretical driving range of up to 1116km, which is a little less than the Toyota Camry but still an amazing range for a family car.

That range figure drops to around 940km using our real-world average consumption number.

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.

Power delivery for the new Accord is pretty punchy and, in most scenarios it’s responsiveness is great. But occasionally, when you’re getting up to speed, there can be a small lag before things kick in.

The Accord handles like a dream and feels firmly planted on the road in corners. Even in high winds, the car feels stable and sure of itself. Delightful.

The cabin is quiet and engine noise is at a minimum most of the time. Around town, the Accord sounds and behaves like an EV. Only once you hit the open road do you get some road noise but it never intrudes on chatting.

It might also be one of the easiest sedans to park and it's got a lot to do with the top-notch 360-degree view camera system and direct steering.

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. 

The Accord comes with a five-year/unlimited km warranty, and an eight-year battery warranty, which are now normal terms for the class.

You get a five-year capped priced servicing program and it costs just $199 per service, which is very competitive.

Servicing intervals could get annoying if you put a lot of kays on your car as they're set at every 12-months or 10,000km, whichever occurs first.

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.
