Kia Optima vs Toyota Corolla

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 final score for this review makes it look as though the Corolla is a middling effort. The scores for each individual section of the review are well considered and fair. The Corolla does lack the practicality of some of its rivals. A lack of an ANCAP rating isn’t great and the powertrain is just okay. But it remains one of the most fun-to-drive hatchbacks on the market today, even seven years into its life, and I would wholeheartedly recommend the Corolla to anyone looking for a small car. If you can forgive some of the quirks, it is a reliable, adorable, fun and efficient small car favourite. 

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’s been around for a good seven years, but the current-gen Corolla hatch is still a smart design. It has a squat stance and looks as though it has sporty intentions (it doesn’t), and the head and tail-light treatment doesn’t look like anything else in the segment.

The Corolla has adorable proportions and a pert little behind in a sea of increasingly boring small SUVs.

However, in SX trim and in the ‘Sunstone Orange’ body colour of my test car, the Corolla gives off rental car vibes. Which is hardly surprising given lower grade Corollas are a favourite of rental companies.

Inside that vibe continues. This is where the Corolla is really showing its age.

There are various shades of grey throughout the cabin, with a mix of hard and soft plastics. The cloth seat trim is drab, which is a shame because some other brands have managed to make cloth cool again. Not Toyota.

The touchscreen sticks up out the top of the dash like an old iPad and the dash design is old but functional. 

There is nothing inspiring about this interior design. In saying that, of those aforementioned rivals, only the Mazda3 and the new Kia K4 have modern cabins.

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?

The Corolla is a small car and that is evident inside. You might bump elbows with your front passenger, but I have no problem with the front leg or headroom.

Those cloth seats might be drab but boy they are comfy, and the fronts have loads of side bolstering. 

The steering wheel has typically clear controls and looks and feels nice. 

As a more, shall we say seasoned model in the segment, the Corolla still has buttons on the dash for things like air con, but not too many. That bulbous centre stack and the centre console, however, could be better designed for the space.

As it is, the wireless charging pad is hidden under it at the far end of the console. It’s a bit fiddly to get your phone in and out. This is also where one of the USB-C ports lives.

The other one is in the central storage bin which is quite small, but also houses a 12-volt outlet. There are no other places to store things because of the rounded shape of the console, which also features a couple of narrow cupholders.

OurCarsGuide bottle had to be squeezed into the door storage cavity - only narrow, short vessels will fit properly.

That 8.0-inch multimedia screen is very easy to navigate, with logical menus and icons. However, it’s almost too basic, which is not helped by the all-white background. It could be a more engaging set-up but it’s also very hard to fault the functionality. Our Apple CarPlay maintained its connection the whole time with the car, too.

Space is quite tight in the rear, although I have enough headroom for my 184cm frame. Legroom is just okay behind my driving position. There’s more space in the back of a Hyundai i30. It’s also dark because of smallish rear windows and thick C-pillars. 

The rear seat backrest is quite upright, but, like the front seats, well cushioned.

Amenities are just average back there - there’s a weird cupholder high on the door, only a passenger side map pocket, no rear air vents and no USB ports, although you could easily use the one housed in the front central bin. There’s a rear fold-down armrest with two cupholders.

The rear seats split and fold 60/40 and they fold flat making for a better loading space.

The good news is the SX (and the base Ascent Sport) come standard with a temporary spare wheel, which is great news for a hybrid model. The bad news is, that reduces boot space to a paltry 217 litres. 

That’s off the pace of all of its key hatchback rivals, including the Mazda3 which has its own cargo concerns at 295L, and the Hyundai i30 with 395L.

The Corolla ZR hatch has more space at 333L but you only get a tyre repair kit instead of a temporary spare. 

If you’re dead set on a Corolla but need more cargo space, consider the smart looking sedan that has 470 litres.

Toyota dropped all exclusively internal combustion engine versions of passenger car models and car-based SUVs last year so the Corolla is now hybrid-only.

The grade we tested is the SX five-door hatchback which is priced from $35,260, before on-road costs. Interestingly, the sedan version, which has a much bigger boot, is $340 cheaper.

The SX sits in the middle of the Corolla range with the Ascent Sport the most affordable (from $32,110) and the ZR the priciest before you get to the fire-breathing GR Corolla hot hatch.

Direct rivals at this approximate price point include the Hyundai i30 N Line ($36,000 BOC), Mazda3 G20 Touring ($37,110), Subaru Impreza 2.0R ($35,490) and the Kia K4 Sport ($35,190), although that is sedan only for now.

You get 16-inch alloy wheels, cloth bucket seats, a synthetic leather steering wheel, auto-dimming rear view mirror, rain-sensing wipers, rear privacy glass, keyless entry and start, dual-zone climate control, USB-C ports, a wireless device charging pad, six-speaker audio, an 8.0-inch colour multimedia display with sat-nav, digital radio, Bluetooth, voice assistant and wireless Apple CarPlay and Android Auto. 

The standard features list could be described as adequate without being overly generous for the price. A head-up display (standard in the ZR) would be nice.

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.

Since Toyota dropped the petrol engine from the Corolla range, it’s a hybrid-only affair.

The powerplant is a 1.8-litre naturally aspirated petrol engine paired with Toyota’s fifth-generation hybrid system that incorporates a lithium-ion battery, which is lighter yet more powerful since the 2022 update.

The Corolla drives the front wheels exclusively via a continuously variable transmission (CVT).

It’s not the punchiest engine and could do with more poke, but Toyota does do hybrids well. 

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.

According to Toyota the official fuel-use figure for the Corolla hybrid hatch is 4.0-litres per 100 kilometres and CO2 emissions sit at 90g/km.

While the trip computer said 4.8L/100km at the end of our week, my own fuel consumption calculation came to 5.8L.

You will only need 91 RON 'standard' petrol to fill up the Corolla.

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.

Most generations of Corollas have been solid, dependable and occasionally, even fun to drive. 

My first car was a Holden Nova GS hatchback, which was a rebadged version of the seventh-generation Corolla. I loved that car. It was zippy, fun and super economical.

The same principles generally apply to the current-gen Corolla. Thankfully, Toyota’s former CEO, Akio Toyoda, insisted all models from the Camry to the Kluger needed to be injected with more fun. And he succeeded with the Corolla. So much so that they've spun off a wild GR performance hot hatch version.

The Corolla sits low to the ground and it just feels much more connected to the road than a small SUV can. Even in mid-range SX guise, the Corolla can hug a corner and there is ample grip to ensure a fun drive on your favourite winding road.

Sure, the hybrid powertrain might not set your heart racing, but it is quick enough from a standing start and it lacks the lag of some of its turbocharged contemporaries. There’s also plenty of poke on tap for a small car when overtaking.

Even though it has a sporting edge to how it handles, the Corolla SX has been tuned for comfort first and foremost and this is another area it excels. The damper set-up ensures the Corolla soaks up speed bumps, nasty potholes and whatever else our shoddy roads can throw at it. At no point in my seven days with the Corolla did I complain about a harsh bump or thud.

Steering has a mechanical feel but it is still sharp, adding to the ‘chuckable’ vibe of this hatchback.

The powertrain can be noisy when pushed and combined with a CVT auto it’s the nicest sounding engine out there. Also, the transition from electric to petrol power isn’t particularly smooth. Other carmaker’s hybrid offerings - like Honda for example - are close to seamless. 

Some road noise gets into the cabin but it’s no deal breaker.

The Corolla is currently unrated by crash safety watchdog ANCAP. It did achieve a maximum five-star rating back in 2018 but that expired at the end of last year.

Safety features are largely standard across all grades and the SX comes with auto emergency braking (AEB) with pedestrian and daytime cyclist detection, lane departure alert with steering assist, speed sign recognition, 'Lane Trace Assist', adaptive cruise control, a blind spot monitor with safe exit assist, a rear cross-traffic alert, reversing camera and front and rear parking sensors and a rear occupant alert.

It doesn’t have a driver attention alert, and it’s all the better for it.

The lane keeping aid is well calibrated and subtle in its interventions, but the adaptive cruise let the speed creep several kilometres over the set speed on several occasions. 

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.

The Corolla is covered by Toyota’s five-year/unlimited kilometre warranty, which, given Kia, MG, GWM, Jaecoo and more have longer terms (not to mention Nissan and Mitsubishi’s conditional 10-year terms) is now officially trailing its competitors.

However, the capped-price servicing plan of up to five years costs just $250 for each service, which is incredibly competitive. The service schedule is every 12 months or 15,000km, whichever occurs first.
