Kia Optima vs Ford Transit Custom

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.

The Ford Transit Custom Trail has plenty of appeal as a work van or a camper fit-out candidate. It’s a well-packaged, comfortable and contemporary van that’s nice to drive and as a bonus, with all-wheel drive it’s given the scope of capability to be able to tackle mild off-roading situations with confidence.

It’s built for work and play and though it’s limited to two-up for travels, the Trail offers so much potential as a camper conversion for adventure seekers its few niggles are easily forgotten when you’re busy making memories.

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 looks like a van but with some striking yet low-key flourishes that all kind of work as a whole. Those include a Trail grille and the matt black alloy wheels. The yellow sticker-pack is a neat touch.

The Trail has more presence than a regular Trend with its 30mm-taller raised suspension and overall adventure-ready look with strong front end and chunky wheel arches.

The striking but low-key theme continues inside with a neatly laid-out yet spartan cabin. The two synthetic leather seats are topped with Trail embossing and lined with yellow stitching.

The cabin is separated from the rear cargo area by a bulkhead, which incorporates a small wired window.

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 van so there are two distinct sections to the Trail, the cabin and the load space.

Firstly, the cabin. More a work-friendly than family-friendly interior, this Trail is a two-seater with plenty of durable plastic everywhere – ready for work and life – as well as charging (with USB-A and -C ports) and storage (including a van-favourite dash-top slot for logbooks etc, outboard moulded cupholders and a nifty pop-out cupholder), all amenities enough to cope with most daily van-related duties.

The seats are comfortable, supportive and have a fold-down lock-in-place armrest.

Now for the load space. There are no seats back there and as such it has plenty of potential as a work van or touring vehicle.

Access to the rear load space is via a barn door at the back and this Trail has a sliding door on both sides.

The cargo area is substantial – 3002mm long (to the bulkhead; 3450mm long if load-through hatch is used), 1392mm wide (between wheel arches) and 1425mm high (floor to roof). Easily big enough for work equipment or recreational gear. It can cope with four Euro pallets (each measuring 1200mm x 800mm) and it has a listed maximum load volume (with the bulkhead) of 6.8 cubic metres.

Load height through the rear barn doors is 531-585mm, depending on how much weight is already onboard.

The load space has the aforementioned metal bulkhead (with window and load-through hatch), load area protection kit (full height walls and moulded floor), LED lights and eight tie-down loops.

Otherwise, this is a load area ripe for customisation. Maybe a plethora of shelves for a tradie, or some bedding and extra storage for an adventurous person or couple.

The 2025.75Y Ford Transit Custom Trail has a MSRP of $61,990 (excluding on-road costs).

Standard features onboard include a 13-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a 12-inch digital instrument display and synthetic leather upholstery with Trail logos on the seats.

Other gear includes an eight-way manually adjustable driver’s seat, keyless entry and start, front and rear parking sensors, climate-control air and automatic LED headlights.

It also has all-wheel drive, LED headlights and daytime running lights, a variant-specific grille, black wheel arch moulding and side strip, yellow exterior decals and 16-inch matt black Trail twin-spoke alloy wheels.

The standard no-cost exterior paint is 'Frozen White'. Anything else – 'Agate Black Metallic', 'Grey Matter', 'Magnetic' or 'Moondust Silver' – will cost you $700.

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 Ford Transit Custom Trail has a 2.0-litre four-cylinder turbo-diesel engine producing 125kW at 3500rpm and 390Nm at 1750-2500rpm.

The Trail has a clever eight-speed automatic transmission and an on-demand all-wheel drive system.

It all works rather well, but it’s a van afterall and as such it is less dynamic and more dependably driveable than perhaps a cross-shopped SUV wagon. However, as an AWD van the Trail can be trusted to keep its grip on wet bitumen, soggy grass and loosely-gravelled tracks and that’s a strong part of its appeal over a 2WD van.

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.

The Ford Transit Custom Trail has an official combined cycle (urban/extra-urban) fuel consumption figure of 8.5L/100km. On this test I recorded 8.8L/100km.

The Trail has a 70-litre fuel tank so going by my on-test fuel figure you could reasonably expect a driving range of about 795km from a full tank of diesel. However, as with any vehicle, once you’ve loaded the Trail with real-world burdens (e.g kids, dogs, camping gear, etc) you’ll soon see that fuel consumption increase.

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.

It’s easy to get in and out of the Trail’s driver seat with a wide-opening door and a big step to help you inside.

The seats are comfortable and it’s simple enough to dial-in your driving position via the tilt-and-reach adjustable steering wheel and manually-adjustable seat.

Word of warning: the auto transmission is operated via a stalk mounted on the right-hand side of the steering wheel column, which takes some getting used to.

Once underway, the Trail is punchy enough around town and in the suburbs with its 2.0L 'EcoBlue' turbo-diesel engine offering a more-than-adequate amount of power and torque (125kW and 390Nm) and its clever auto helping out with nifty moves through traffic (for a van, anyway).

Visibility is impressive from the cabin and you’re afforded a convenient vantage point with the Trail standing a bit taller than its regular Transit Custom stablemates as it’s on lifted suspension, but feeling composed on most surfaces.

The Trail has a listed kerb weight of 2046kg and a turning circle of 12.1m, pretty standard for a long wheelbase van, so this is not an insubstantial vehicle and it’s a bit tricky to 'flip a u-ee' if the situation demands it.

It has six drive modes – 'Normal', 'Eco', 'Slippery', 'Tow/Haul', 'Sport', 'Trail' – which each adjust engine torque, throttle response and traction control, among other things, to suit the road surface and conditions.

But we’re all here to see how it goes off-road, aren’t we?

Well, obviously this is no rock-crawling machine and it’s not intended to be. It’s best thought of as having an all-wheel drive system that gives this van mild off-road capabilities, as in it can tackle wet bitumen, soggy grass, lightly corrugated bush tracks and very shallow mud puddles with more confidence than the Transit Custom Trend it's based on.

In a nutshell, the AWD Trail will be able to handle most low-level traction-compromised scenarios. But it does not have enough ground clearance, wheel articulation, grip or underbody protection to tackle any terrain beyond modest off-roading.

Speaking of grip, the Trail as standard rides on Bridgestone Duravis R660 (215/65 R16) rubber, a van/light truck commercial tyre and they are not so well suited to dirt tracks and the like. Grippier all-terrain tyres would help this van perform slightly better off-road than on its showroom rubber.

In its favour, the Trail has a front skid plate and underbody protection in case it cops some knock from the ground during its adventures.

Not in its favour, however, especially as a potential touring vehicle, is the fact it has a space-saver spare wheel and tyre.

If you’re thinking of using your Trail as a tourer, it’s worth knowing payload is listed as 1179kg, maximum braked trailer towing capacity is 2500kg, Gross Vehicle Mass (GVM) is 3225kg and GCM is 5725kg.

The Ford Transit Custom was tested as part of ANCAP’s Commercial Van Safety Comparison in 2024 and received a Platinum score “achieving a near-perfect score in safety assessments”, according to ANCAP.

The Trail has all of the Custom’s driver-assist tech and safety features, including six airbags (driver, front passenger, front side curtain and front side seat), as well as AEB, adaptive cruise control (with stop and go), traffic sign recognition and lane centering, blind-spot monitoring and assist, rear cross-traffic alert, forward collision warning, hill launch assist, side wind stabilisation, front and rear parking sensors, a rear view camera (with 180-degree split view) and on-board tyre pressure monitoring.

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.

Ford’s five-year/unlimited kilometre warranty applies to the Trail.

Servicing is set down for every 12 months or 30,000km and capped-price servicing is offered. Four scheduled services will set you back $2000 (including a brake fluid change at year three) which isn't over the top for a vehicle of this type.

Ford Australia has about 195 independent Ford dealers in Australia, with many located in metropolitan or suburban areas.
