Kia Optima vs Toyota HiAce

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.

When you consider its competitive pricing (particularly for fleets), resolute resale value, robust construction, rock-solid reliability, excellent load-hauling ability, five-star safety and all-round practicality, it’s not hard to understand why the HiAce is such a popular workhorse. It’s not perfect, like any van, but when performing its intended role it’s very good.

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.

Toyota’s unwavering adherence to rear-wheel drive ensures the HiAce has an inherent traction advantage over its predominantly front-wheel-drive rivals, particularly when hauling heavy payloads on low-grip surfaces.

Rear-wheel drive also ensures the front wheels can be turned sharply enough for its 3210mm wheelbase to deliver an impressively tight 11.0-metre turning circle. And its 1990mm height also allows access to underground loading docks and multi-storey car parks.

The chassis design is simple and robust with MacPherson strut front suspension, a leaf-spring live rear axle, variable-ratio rack and pinion steering and (on automatic variants) four-wheel disc brakes.

There’s no mesh-type cargo barrier or solid bulkhead between the cargo bay and cabin (but both are also available as genuine accessories) and the black door-handles and unpainted black plastic front and rear bumpers are designed to best withstand the wear and tear often evident in these areas on hard-working vans.

The two-tone dash layout is neat and functional, with clear analogue instrumentation and dash controls (mostly physical dials and buttons) that are easy to reach and operate. And it sticks with a good old lever-type manual handbrake instead of an electric one. All are chosen for their rugged simplicity.

The only useful item missing is a fold-down inboard armrest for the driver’s seat, offered by numerous rivals to reduce neck and shoulder strain during long days behind the wheel.

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?

Our barn-door-equipped test vehicle has a hefty 2245kg kerb weight and 3300kg GVM, which results in a genuine one-tonne-plus payload rating of 1055kg. Up to 120kg of that weight can be carried on Toyota’s triple roof-rack set.

It’s also rated to tow up to 1500kg of braked trailer, which is less than some rivals but in reality should adequately cover most towing requirements of van operators.

And with its 4800kg GCM rating (or how much weight it can legally carry and tow at the same time), that means it can carry its maximum payload while towing its maximum trailer weight. So, that’s a combined total of more than 2.5 tonnes of cargo-carrying ability, which would comfortably meet or exceed most job requirements.

The generously-sized cargo bay, which offers an impressive 6.2 cubic metres of load volume, is accessed from either side through sliding doors with large 1010mm openings, or from the rear through the optional barn doors which can be opened to 180 degrees (with special lower hinges to hold them there) allowing easy access for forklifts.

The cargo bay is 2530mm long, 1760mm wide and 1340mm high and with 1268mm between the rear wheel housings it can swallow up to two standard Aussie pallets or up to three Euro pallets, held in place by a choice of six load-anchorage points.

There’s plenty of internal lighting, the walls and doors are lined to mid-height and the roof features a full-length internal lining, which is unusual for vans and we suspect contributes to suppression of tyre noise emanating from the rear wheel housings.

Cabin storage includes a large bottle holder and bin in the base of each front door, small-bottle/cupholders on either side of the dash and in the centre, plus a single glove box. The well-designed centre console offers another two bottle holders plus large internal storage, which is capped by a hinged lid that multi-tasks as a shallow storage tray and handy work desk.

Our test vehicle is equipped with Toyota’s ubiquitous 2.8-litre four-cylinder turbo-diesel shared by all models in the HiAce range. However, ours is equipped with the optional six-speed automatic and rear barn doors which raises the list price to $51,636.

Even so, that’s still within the ballpark of its closest rivals including the LDV G10+ Barn Door ($40,063), Hyundai Staria Load Barn Door ($46,740), and Ford’s new Transit Trend LWB Barn Door ($57,590).

Our example is also equipped with a solid-walled left-side sliding door (in preference to the standard offering with window), which HiAce buyers can specify at no extra cost when ordering.

The two-seater HiAce comes standard with 'French Vanilla' paint and 16-inch steel wheels with replaceable plastic covers, 215/70R16 tyres and a full-size spare, but there’s no protective load-floor liner for the cargo bay (a Toyota genuine accessory is available).

There’s also halogen headlights and DRLs (no fancy LEDs here, folks) and the neat two-tone cabin has a tilt/reach adjustable leather-accented steering wheel, power-adjustable lumbar support on the driver’s seat, one USB port and two 12-volt cabin sockets, plus a large centre console that offers numerous storage options.

The driver also gets a 4.2-inch driver’s info display and there’s an 8.0-inch touchscreen (plus steering wheel switches) to control the two-speaker infotainment system, which offers multiple connectivity including Apple CarPlay/Android Auto, Bluetooth, digital radio and more.

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.

Toyota’s well-proven 1GD-FTV 2.8 litre four-cylinder turbo-diesel, which also powers Toyota’s HiLux, Fortuna and Prado model lines, produces 130kW at 3400rpm and (in auto models like ours) 450Nm of torque between 1600-2400rpm. Its Euro 5 emissions compliance doesn’t require AdBlue, which minimises maintenance and running costs.

The refined and smooth-shifting six-speed torque converter automatic offers the choice of sequential manual shifting if required. Fuel efficiency is also optimised with full torque converter lock-up on fourth, fifth and sixth gears, along with overdrive on fifth and sixth being ideal for highway driving. The inherent traction advantage of rear-wheel drive is enhanced by an electronically controlled automatic limited-slip diff.

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.

Toyota claims combined average consumption of 7.9L/100km for our test vehicle, but the dash readout was showing 11.0L/100km when we stopped to refuel after 270km of testing.

This was conducted with the engine’s auto start/stop function switched off and comprised a mix of city, suburban and highway driving, of which about one third was hauling a near-maximum payload.

Our own figure, calculated from actual fuel bowser and tripmeter readings, was higher again at 11.8, which still isn’t bad for a vehicle with a kerb weight exceeding 2.2 tonnes driven mostly in busy urban traffic and hauling almost one tonne during our test. So, based on our ‘real-world’ consumption figures, you could expect a driving range of around 600km from its 70-litre tank.

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 for drivers of most shapes and sizes to find a comfortable driving position in the spacious cabin, given its height/reach adjustable steering wheel, large left footrest and supportive seating with power-adjustable lumbar support.

Although there’s a huge blind spot over the driver’s left shoulder created by the solid walls of the cargo bay, active driver aids including blind-spot monitoring, rear cross-traffic alert and rear-view camera minimise the potential hazards of changing lanes and reversing out of driveways into busy traffic.

Braking is reassuringly strong and the steering is responsive, with easy manoeuvrability thanks to the conspicuously tight turning circle and lightness of the variable-ratio steering at parking speeds.

The ride quality is reasonably supple when unladen or lightly loaded and, for a van without a bulkhead between the cabin and cargo bay, has comparatively low internal noise levels at speeds up to 80km/h.

The 2.8-litre turbo-diesel, with its sizeable 450Nm of torque, has strong low-rpm response and displays good flexibility in city and suburban driving.

Its performance is optimised by the smooth-shifting six-speed auto, which also delivers fuel-efficient highway travel that requires less than 2000rpm to maintain 110km/h. The sequential manual-shifting function can be handy in certain situations, like carrying/towing heavy loads in hilly terrain.

To test its GVM rating we forklifted 890kg into the cargo bay, which combined with the driver equalled a total payload of 990kg that was only 65kg shy of its 1055kg limit.

The stout rear leaf-springs only compressed about 30mm under this loading, which left more than 60mm of static bump-stop clearance that was more than enough to ensure there was no bottoming-out on our test route.

The turbo-diesel’s ample torque made light work of hauling this payload in city, suburban and highway driving. It was also particularly strong in the hills, where it easily conquered our 13 per cent gradient, 2.0km-long set climb in third gear.

Engine braking on the way down, in a manually selected second gear, wasn’t as strong but far from disgraced given the near one-tonne payload it was trying to restrain. Even so, its four-wheel disc brakes were more than capable of keeping speeds in check.

Our only criticism is the high internal noise levels at highway speeds, when tyre roar through the rear wheel housings can become intolerable over long distances, particularly on coarse bitumen surfaces with an empty cargo bay amplifying the noise.

In our experience, this is a problem shared by all vans at these speeds if they’re not equipped with a sealed cabin bulkhead. So, if your work involves a lot of highway travel, we would recommend fitting one that's available in Toyota’s genuine accessories range. Or buying some earplugs.

The HiAce has a five-star ANCAP rating awarded in 2019 which will expire in December 2025. It comes with seven airbags plus benchmark active safety features including AEB with pedestrian and daytime cyclist detection, lane departure alert with braking assist, speed sign recognition, blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, reversing camera and more.

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.

It is covered by a five-year/unlimited km warranty. Scheduled servicing is a relatively short six months/10,000km intervals, whichever occurs first. Capped-price of $290 per service covers the first six scheduled services over three years or 60,000km.
