Kia Optima vs Zeekr X

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.

It's a good thing in a small package, this Zeekr X, and there are a lot of things I like about it. In fact, the only sticking point for me is the price. But that's all about perspective. If you see this as a newcomer Chinese brand, then yes, there are a lot of more affordable options out there. But if you see it as a premium player, it's really a more affordable version of a Volvo.

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.

The visual changes aren’t massive. This AWD version welcomes a couple of new exterior colours, including the 'Matt Khaki Green' of our test car. It also gets the two-tone black roof and there are new 20-inch alloy designs.

Elsewhere, it's the futuristic-style of design we’re used to which differentiates the X from its Volvo EX30 twin under the skin.

Inside, this is a seriously well-equipped and polished-feeling small SUV, and — unlike some of the newcomer brands to Australia — it all feels very high quality and well put together. And that includes the material choices.

I don’t even hate the fact that most of the functions are controlled via this screen, thanks to the little shortcuts glued to the home screen. I do, however, hate the fact that there’s no easy way to change the wing mirrors or shortcuts for toning down some of the safety stuff.

That aside, though, it’s a nice and high-quality feeling space.

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?

You know you're in a small vehicle when you can't fit two large (not those crazy American-style jumbo cups, just normal coffee-shop takeaway) coffees in the cupholders, but so it is with the Zeekr X.

The small SUV's 4432mm length, 1836mm in width and 1566mm height doesn't leave much room to spread out up front. There's ample room for driver and passenger, of course, but we are talking about a small vehicle here.

Clever storage helps to mitigate that, though, especially the super-deep storage space in the centre console and the very clever fridge that separates the driver and passenger seats.

Weirdly, though, the space doesn’t feel overly tight in the back seat. We had a massive baby seat in there, and that fit without issue. And full size humans can genuinely get pretty comfortable. I'm 175cm, and I had enough knee and headroom.

In the boot, there’s 404 litres of volume with the rear seats upright and 1247 litres with them folded flat. And it’s worth pointing out this isn’t intended to be a family car, but there’s certainly enough space for the shopping... and a pram.

This is a small SUV with a LOT of stuff. There are two trims in the Zeekr X range – the entry-level rear-drive model is $48,900, drive-away, while the all-wheel drive version we've tested is $57,900 on the road.

The obvious comparison is to the Volvo EX30, which shares its platform with the Zeekr X through both brands' Chinese parent company Geely.

As of right now, the cheapest single-motor Volvo is $56,051, drive-away in NSW, or $49,990 plus on-roads, making the Zeekr version much, much cheaper.

Anyway, outside there are 19- or 20-inch alloys, though our test car is fitted with the optional 20-inch black alloys, paired with a black-with-red-highlights interior treatment, which adds $2000 to the price.

Ours is also fitted with the electric front doors which open or close at the push of a button, and back doors that unlatch, but don’t fully open, the same way, which adds another $2000.

Both trims also get heated and cooled front seats, and heating in the rear window seats, but this AWD version also adds a massage function for front seat riders. 

There’s also wireless charging, a 13-speaker Yamaha sound system and — very cool, literally — is the little drinks fridge between the front seats in the AWD variant.

Tech is handled by a 14.6-inch touchscreen with Apple CarPlay and Android Auto and there’s a head-up display for the driver.

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 big news here is a more powerful rear motor – meaning you get more grunt whether you opt for the rear-wheel drive or this all-wheel drive.

In rear-drive form, that boosts your outputs from 200kW to 250kW, dropping the sprint to 100km/h to 5.6 seconds. In AWD guise, your new outputs are 365kW (up from 315kW) and 573Nm, and your sprint to 100km/h falls to 3.7 seconds.

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.

This is where it starts to get weird. The rear-drive Zeekr X is fitted with a 61kWh LFP battery, which can accept up to 230kW DC fast charging, taking you from 10 to 80 per cent charged in just 18 minutes. Total claimed range is 405km.

The flagship AWD, though, charges at a slower rate. It gets a 66kWh NMN battery and can only be charged at 150kW, meaning the same charge takes 30 minutes. Zeekr is promising a 415km driving range between charges.

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.

Short answer? Pretty good, with some caveats.

I'm partial to a firmer ride. I find some Chinese car companies can feel like they get their suspension bits from Captain Snooze, such is the soft, pillowy ride served up. And to be honest, it makes me a little seasick at times.

The Zeekr is not like that. It has firmness dialled into the ride equation and can feel harsh at times, but also improves the drive experience, delivering connection and engagement at the cost of some sharpness on the wrong road. 

It's also faster than the model it replaces, but it's also one of those cars in which the real-life feeling doesn't quite match the on-paper promise.

This thing serves up supercar speed, but it doesn't feel like it from behind the wheel. Instead, the acceleration - especially from a rolling start - feels potent, but not biblical.

From a standing start it pauses for a moment, almost like an internal-combustion vehicle might, before delivering a quick (but not stratospheric) flow of power. None of that is a bad thing, by the way. Who wants their small SUV to accelerate like a supercar?

It's otherwise an entirely pleasant drive. The cabin is serene and quiet and it's a small car that doesn't feel like one. There's nothing light or tinny about the drive experience, instead there's a heft and quality.

The Zeekr X wears a maximum five-star ANCAP safety rating, earned in 2024, which means the long list of required active safety stuff is present and accounted for, all wrapped up in what Zeekr calls its 'Intelligent Driving Assist System'.

There are five cameras, five radars and 12 sensors, which is a crazy number for a car this small.

And this is also not a car in which I was desperately trying to figure out how to deactivate any of the active safety systems – save the overzealous over-speed warning – which is a win these days, too. 

There are also seven airbags, including a centre front airbag.

The Zeekr X is fitted with ISOFIX anchors on the rear outboard seats and top tether anchorages for all rear seating positions.

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.

Zeekr's coverage is an underwhelming five-year, unlimited-kilometres, while the drive battery is covered for eight-years or 160,000km. There’s five years' of roadside assistance thrown in, too.

Service intervals are 20,000km or 12 months, with five years' of ownership setting you back a hefty $3072; an average of $614 per workshop visit.

There are currently 16 Zeekr dealers in Australia - two of which are 'pop-up' sites rather than full retail centres.

Multiple locations in Melbourne, Sydney and Brisbane with the ACT, Adelaide and Perth also covered. Others include Geelong and the Sunshine Coast but so far you're out of luck in Tassie or the NT.
