Honda Odyssey vs Kia Optima

What's the difference?

The Honda Odyssey isn’t a bad choice for those looking to ferry around a large gaggle of people, but its far from the best option.

The first two rows are great and are supremely comfortable for those four occupants, but third-row usage will depend on how much those passengers are susceptible to motion sickness.

However, the Odyssey’s biggest weakness might be its sluggish engine and mundane CVT, with rivals like the new Kia Carnival and even Toyota Prius V offering better performance and better economy, respectively.

Still, the Honda Odyssey, and people movers in general, remain a solid option for those that don’t want another SUV or value the practicality and space afforded.

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.

Gone are the days where people movers could be considered daggy or uncool. No, please, don’t click away, we’re serious!

The 2021 Honda Odyssey features a new front grille, bumper and headlights that combine for a much more imposing and aggressive front fascia.

The chrome highlights look especially good against the 'Obsidian Blue' paintwork of our test car, at least to our eyes, and between this and the new Kia Carnival, people movers might just be cool again.

In profile, the 17-inch wheels do look a little small next to the massive doors and huge panels, but they do feature a funky two-tone look.

The chrome touches also follow along the Odyssey’s flanks and are found in the door handles and window surrounds to break things up a bit.

From the rear, the Odyssey’s large dimensions are hard to hide, but Honda has tried to jazz things up with a roof-mounted rear spoiler and more chrome around the tail-lights and rear fog light surrounds.

Overall, the Odyssey looks handsome and confident without straying into the ‘trying too hard’ or ‘over the top’ territory, and if anything, at least it’s not another high-riding SUV, which are quickly overtaking streets and car parks the world over.

Step inside and the Odyssey’s layout is nothing special, but gets the job done.

The first- and second-row seats are plush and comfortable, while the dashboard also features woodgrain touches to lift the interior ambience.

The 8.0-inch multimedia screen sit proudly in the centre stack, while the shifter is on the dashboard to maximum interior space.

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.

Measuring 4855mm long, 1820mm wide, 1710mm tall and with a 2900mm wheelbase, the Honda Odyssey is not just an imposing behemoth on the outside, but also a spacious and practical people mover on the inside.

Up front, occupants are treated to plush and comfortable seats with electronic adjustment and individual fold-down armrests.

Storage options abound, with deep door pockets, a dual-chamber glove box, and a tricked-out centre storage console that can retract into the centre stack and features two hidden cupholders.

Because of the compact engine and transmission package, and the fact the centre console tucks away, there is actually just empty space between the two front occupants, which is a missed opportunity.

Maybe Honda could have put another storage bin there, or even a cooled box for chilled drinks on long road trips. Either way it’s a notable, unexploited cavity.

The second-row seats are probably the place to be in the Odyssey, though, with its two captain’s chairs offering supreme comfort.

Adjustability is also plentiful, with forward/backwards, recline and even left/right positioning available.

However, while there are cupholders and roof-mounted climate controls present, there really isn’t much else to keep second-row occupants, well, occupied.

Would be nice to see some charging ports or even entertainment screens to keep kids and adults placated on long journeys, but at least the head, shoulder, and legroom is generous.

In the third row, it’s a tighter squeeze, but I managed to get my 183cm (6'0") frame comfortable.

The three-row bench is the least comfy place to be, but there is a charging outlet and cupholders back there.

Those with child seats also take note, the second-row captain’s chairs top-tether anchor point is very low down on the seat back, meaning you might have to max out the strap length to get it there.

Also, because of the captain’s chairs, the top tether strap can be knocked off quite easily, as the inner shoulders of the seats are smooth offering nothing for the strap to catch onto if pushed towards the middle of the car.

And you can’t even install the car seat in the third row because the bench seat doesn’t feature any ISOFIX points. 

With all seats in place, the boot will happily swallow 322 litres (VDA) of volume, more than enough for groceries, school bags or even the stroller.

However, the boot floor is quite deep, making the retrieval of bulkier and heavy items a little cumbersome.

With the third-row folded, though, that cavity is filled in and the Odyssey features a completely flat floor then able to take on 1725L of volume.

Honda has even found a place for the space saver spare wheel, though it’s not underneath the car or tucked into the boot floor as you'd expect.

The spare is under the two front seats, and requires the removal of some interior carpets and trim to access. 

It’s not in the most convenient of places, but props to Honda for getting one in there when other seven-seaters just opt for a puncture repair kit. 

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. 

All 2021 Honda Odysseys are powered by a 129kW/225Nm 2.4-litre ‘K24W’ four-cylinder petrol engine, which drives the front wheels via a continuously variable automatic transmission (CVT).

Peak power is available at 6200rpm, while maximum torque is on stream from 4000rpm.

Honda diehards might note the K24 engine designation and be reminded of the rev-hungry 2.4-litre unit of the Accord Euro from the early 2000s, but this Odyssey’s powerplant is built for efficiency rather than performance.

Compared to the likes of the Kia Carnival (which is available with a 216kW/355Nm 3.5-litre V6 or 148kW/440Nm 2.2-litre turbo-diesel) the Odyssey is noticeably down on power.

The Australian Odyssey also doesn’t feature any form of electrification, such as the Toyota Prius V, which would excuse the lower outputs and push the Honda people mover more into green territory.

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 2021 Honda Odyssey, regardless of grade, will return a fuel consumption figure of 8.0 litres per 100km, according to official figures.

This betters the fuel economy of the petrol-powered Kia Carnival (9.6L/100km), as well as the Mazda CX-8 (8.1L/100km) and soon-to-be-replaced Toyota Kluger (9.1-9.5L/100km).

In our week with the Odyssey Vi LX7, we managed an average of 9.4L/100km in a mix of inner-city and freeway driving, which isn’t too far off the official figure.

Though the fuel consumption isn’t too bad for a naturally aspirated petrol engine, those who want to save costs at the bowser should look to the petrol-electric Toyota Prius V hybrid, which sips just 4.4L/100km.

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.

Though the Honda Odyssey looks like a bus on the outside, it doesn’t feel like one behind the wheel.

The Odyssey drives differently to an SUV, which is a good thing, feeling more hunkered down and connected to the road compared to the wallowy and bouncy nature of some high-riders.

Don’t get me wrong, this isn’t Honda’s best handling model, but there is certainly enough feedback in the steering wheel to know exactly what’s happening underneath, and the Odyssey always feels predictable, regardless of road condition.

And because visibility is excellent all around, the Honda Odyssey is just an easy, no-fuss car to drive.

The second-row is also great while on the move, and might actually be the better place to be.

The seats do a great job at soaking up little bumps and road imperfections, and there is plenty of room to stretch out and relax while someone else handles driving duties.

It’s a shame, then, that there isn’t more going on in the second row to keep passengers happy.

The third-row seats, though, are nowhere near as comfortable.

Maybe it’s the fact they are positioned right over the rear axle, or it’s the thick and vision-obscuring C- and D-pillars – or a combination of both – but time in seats five, six and seven, aren't ideal for those prone to motion sickness.

Maybe kids, or those with stronger stomachs can get comfortable in the third row, but for us, it was not a pleasant experience.

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. 

Like all new Hondas sold in 2021, the Odyssey comes with a five-year/unlimited kilometre warranty, with six-years of rust protection assurance.

Scheduled service intervals are every six months or 10,000km, whichever occurs first, but this is much sooner than the industry standard of 12 months/15,000km.

According to Honda’s 'Tailored Service' price guide, the first five years of ownership will cost buyers $3351 in servicing fees, averaging out to around $670 per year.

The Kia Carnival petrol meanwhile, is about $2435 to service over five years, averaging out to be about $487 per year.

The Toyota Prius V also needs to be serviced every six months/10,000km, but the cost of the first five years of ownership totals just $2314.71 – more than $1000 less than the Odyssey.

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.
