Kia Optima vs Nissan Navara

What's the difference?

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.

While it won’t appeal on the value front as much as its Mitsubishi Triton engineering twin, the Navara’s tweaks from Premcar make it a more comfortable and livable thing. 

The extra cost is worth it for how much better it is on the road, plus you get more features, regardless.

Whether the changes to the Navara are sexy enough to get people in the dealership door is another question, but anyone who takes this over a Triton won’t be disappointed.

If it's for work, the SL or ST will do. If it's doubling as a family car, the Pro-4X is worth the outlay.

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.

Nissan has done well to inject its own design flavour into the ute, because even though there’s inevitable similarity in the silhouette, it doesn’t just look like a Triton.

Impressive given a lot of the car is the same, and Nissan couldn’t change any of the hard points the Triton comes with. In fact, the Navara’s dimensions are largely the same as the Triton, coming in at 5320mm long, 1930mm wide and 1815mm tall.

The biggest Nissan-specific design element is a nod to the Navara’s heritage, the three little vent lines above the grille hark back to the original D21 generation ute which had these holes in the bonnet.

It’s subjective to some extent, but I reckon the Navara has the Triton beat on the design front.

Depending on the variant, you get some other indicators that this is no Triton, including a sports bar on the rear of the cabin with ‘Navara’ cut into it, or Pro-4X decals if that’s the variant you go for.

Given the lifestyle and off-road focus of the Pro-4X, it also has a bit more trim inside and out to feel more rugged and premium.

The Navara’s new interior is a big step up over the previous generation, even if it is genuinely all-Triton in there. The biggest change is the Nissan badge on the steering wheel.

It’s a ute, so there’s still a lot of plastic, cheap materials and even the nicer looking surfaces are in a few spots made of gloss black plastic (sometimes called piano black) which gets smudged easily and after a short while.

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?

It’s a bit of a shame the Navara doesn’t benefit from the changes Nissan has been making to its interior design and layout recently, because it leaves older Nissans in the dust, in terms of design and ergonomics.

But, the Mitsubishi Triton’s interior isn’t a bad one for the Navara to have inherited, because it just works. It’s uncomplicated and sensible, if a little boring.

There are physical buttons for shortcuts, and the tech is relatively straightforward, even if it does also carry the downside of Android Auto being wired-only. It adds to the somewhat dated feeling the Navara’s interior carries, but the physical space itself is rather sensible.

The Navara’s seats are comfortable, and as the driver it’s easy to find your own preferred position, with the electric adjustment in higher variants being an extra help there.

The driving ergonomics and visibility are also good, which lines up well with the Navara’s driving dynamics and makes it feel less like you’re pedalling a big dual-cab around.

Behind the driver, there’s not heaps in the way of amenity, but the addition of USB ports once you’re past the base SL is welcome for second-row passengers, and the space isn’t cramped by any means.

The Navara has a tub capable of easily fitting a Euro pallet, according to Nissan’s specs, but with its distance of 1135mm between wheel arches, it won’t fit an Aussie pallet. The tub is almost square, at 1555mm long and 1545mm wide, and 525mm tall. 

Plus there’s the 3500kg towing capacity and its payload ranging between 964kg for the Pro-4X or up to 1064kg in the base SL.

The new D27 generation Navara starts from $53,348, before on-road costs, so it’s already more expensive than the Triton it’s based on, but we’ll get into the main, somewhat oily reasons for that in a bit. 

The Navara’s available in four variants at launch, SL, ST, ST-X and Pro-4X. They’re all 4X4 dual-cabs, so it’s mainly the features for each trim level that make the difference when it comes to pricing.

The SL starts off with a lot of the basics covered. There are LED headlights and tail-lights, climate control, the same 8.0-inch multimedia touchscreen as the rest of the range and digital radio as well as Android Auto and Apple CarPlay.

Its aforementioned touchscreen is also a little larger than the one in the Triton it’s based on. Then there’s the 7.0-inch driver display screen which lives between the two physical dials.

At this point in the range the steering wheel is polyurethane and the floors aren’t carpeted, just covered with vinyl. It’s a work ute and it feels like one.

Things pick up slightly with the ST, which starts from $56,765, and gains alloy wheels, auto-folding mirrors, a leather-accented steering wheel and floor carpet, plus now side-steps and a sports bar. It also adds USB ports in the second row for charging, so it’s probably the minimum grade you’d want if you’re ever going to have kids in the back. Essentially, it gains a few things that make it feel a little more livable without getting too fancy.

The ST-X is a fair step up in price, it’s $63,177, but gets better suspension, 18-inch alloys, leather-accented and heated front seats and a power adjustable driver's seat, dual-zone climate and a wireless phone charger.

It also gains a centre limited-slip differential, drive modes more compatible with off-roading, different styling elements and push-button start, so you don’t need to use the physical key.

The top-of-the-range (until the Warrior arrives) is the $68,418 Pro-4X with more design changes, all-terrain tyres, a black sports bar and roof rails, contrast stitching and specific seats with Pro-4X styling. It’s the variant Nissan Australia expects to be the most popular, too. It also has the same diff and better suspension the ST-X gains.

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.

A 150kW/470Nm four-cylinder turbo-diesel engine lies under the bonnet, which falls a little short of some rivals, but isn’t glaringly weak.

Its power lines up with, for example, the Toyota HiLux, but torque falls short of its rival’s 500Nm. It’s the same story for the Ranger, though that ute slips a nose ahead with 4.0kW more than HiLux and Navara in its four-cylinder guise.

The Navara’s six-speed automatic transmission also sends that power and torque to all four wheels, though how exactly it gets there depends on the spec and whether you have a centre differential or not.

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.

From the Navara’s 75L tank, a claimed 7.7L/100km is used on the combined (urban/extra-urban) cycle, though on the launch drive we saw the trip computer hovering around 9.0L/100km.

With a few hundred kilos in the tray, that jumped up to the low 11s.

Hypothetically, if you manage to get close to Nissan’s claimed consumption, you should be able to get more than 900km out of a single tank of diesel. Nissan’s claim isn’t too outrageous, either, considering the type of driving a car launch generally consists of isn’t normally conducive to favourable fuel consumption figures.

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.

Now we get to the biggest reason you’d consider a Navara over the Triton it’s based on.

While the Navara benefits from having a relatively new platform underneath it - thanks Mitsubishi - it’s still a ladder-frame dual-cab ute so expectations weren’t exactly on the floor, but they also weren’t sky-high.

And sure, a lot of the details about the new Navara aren’t groundbreaking, nor is much of the way it drives - but the changes Premcar has made to the suspension in this ute are well worth the extra outlay.

What Premcar has done with the Navara, on what we would guess is a relatively constrained budget, is find the most cost-effective way to make the ute better to drive.

They went with upgraded dampers which have been tuned to balance control and comfort with the ute’s off-road ability.

The result? A very controlled front-end, more communicative steering and confidence on the road to drive over even rough surfaces without fear of being flung off the road. Ladder-frame utes don't normally feel so controlled over rough surfaces at high speeds.

It’s worth noting that while the SL and ST still benefit from the suspension upgrades, the ST-X and Pro-4X in particular are much better to drive than you’d expect from a dual-cab ute.

Some of the roads around Canberra are particularly rough, even close to town where the speeds are lower, but the Navara handled myriad surfaces and conditions on- and off-road, in the soaking wet and when it was bone-dry.

Aside from one particular section of the launch that may have just been a little unkind to the ‘stiffer’ sidewalls on the ST-X compared to the Pro-4X, the Navara’s behaviour was not only confidence-building, but allowed for a degree of fun not normally present in the class.

The steering feel left no guesswork necessary, and there’s not a huge on-centre dead-spot as is often the case in a dual-cab. Nice and direct without being too heavy.

The Navara’s weak point, which still gets a pass mark, is probably that its drivetrain now feels older than the ute in which it lives. The outputs are passable, and the transmission finds the correct place well enough, but in a world of 10-speed autos in Rangers or petrol plug-in hybrids, a bog-standard turbo-diesel with six gears has to be bang-on perfect to keep up. 

The Navara’s is adequate, but once you’re used to it, the drive experience is a step above most in the ute segment in terms of control, something that’s hard to come by in this segment.

It translates well to off-roading, where the ute’s front-end settles very quickly over ridges and undulating surfaces without the harshness of a too-stiff set of dampers.

Unsealed roads feel easily dispatched even at relatively high speeds, and with the right tyres (a la Pro-4X) the Navara is a seriously capable thing.

If you find yourself the owner of a D27 Navara and never leave the bitumen, you’re missing out.

The new Navara inherits the Triton’s maximum five-star ANCAP rating from testing in 2024. It scored notably well in Child Occupant protection, though its score for Safety Assist isn’t as high as some rivals.

Eight airbags mean the Navara’s got occupants cushioned in case of the worst, while the whole range has the same suite of safety tech, including a surround-view camera, forward collision warning and AEB, front- and rear-cross traffic alert, driver monitoring and traffic sign recognition, front and rear parking sensors and trailer sway control.

The Navara’s driver monitoring, however, suffers the same overzealousness as the Triton. Nissan didn’t reprogram any of the ADAS systems which means the car will regularly accuse you of being distracted if you’re not looking directly at the road ahead. Checking mirrors or a map in the centre screen will trigger this.

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.

If you have concerns about common problems, issues, reliability ratings and durability, you should check out our Kia Optima problems page.

Nissan’s 10-year/300,000km warranty is fantastic but applies only if you service with Nissan. It’s five years with no kilometre limit otherwise. 

There’s five years' of flat-price servicing at $499 per visit, every 12-months or 15,000km, whichever comes first.

Roadside assist is also free for a decade if you service with Nissan, or a year otherwise.

Given there are around 180 Nissan dealers nationwide, finding one shouldn’t be a challenge.
