Kia Optima vs Peugeot 5008

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 answer is, I think, two-fold - price and badge. Peugeot Australia has a job on its hands to turn things around as 2020 was a tough year and 2021 is shaping up to be almost as hard. There aren't any significant changes to the 5008 to make it suddenly stand out from the crowd because it already did. So the badge's cachet isn't matching the premium pricing.

Peugeot's SUVs are very popular in Europe but barely make a dent here. Because there isn't a bait-and-switch cheaper model to lure buyers off the street, it's a harder sell. Peugeot's glory days of the late 1990s and the late 1970s before mean the people who have fond memories of the badge are older and probably don't have any attachment at all to the French lion. Perhaps the re-energised 2008 will start that conversation, except it's not cheap either.

Having said all that, it's hard to see why folks with over fifty grand to spend on a seven-seater - and there are plenty of those - aren't paying more attention to the 5008. It's a striking presence, is practical but isn't overbearingly large or even slightly clumsy. It may not have AWD but hardly anyone ever uses that. It'll handle the city and the motorway and, as I discovered, biblical rain all in its stride. Like its 3008 sibling, it's a mystery there aren't more out there.

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 5008 was always the slightly awkward big brother to the 3008. That's not to say it was (or is) ugly, but the bigger box fitted to the back is far less racy than the 3008's fast back. 

There's not much change at that end, so the cool claw lights carry the can for style. 

In profile, again, it's a little awkward (compared to the 3008) but some nice work with various materials and shapes help to reduce its bulk.

The front is where the facelift action has happened. I was never completely convinced by the front end of the 5008 but the reworking of the lights to look less like they were squeezed out of a tube of toothpaste is a marked improvement. 

The updated lights work beautifully with the new frameless grille. The fang-style daytime running lights, that debuted on the gorgeous 508, look fantastic here on the 5008. It's a superb job.

Inside is largely unchanged, which is to say it's still brilliant. It's really one of the more inventive interiors in any car, anywhere and is a joy to sit in. 

The seats look brilliant, even more so in the diesel with their fine stitching and racy shapes. The wacky 'i-Cockpit' driving position works much better in more upright cars like SUVs and is present and correct while the new 10.0-inch screen also looks good. 

Even if you're not interested in buying one of these, if you're passing a Peugeot showroom, get in and have a look, feel the materials and wonder why more interiors aren't this cool.

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?

Legroom is good in the middle row, with plenty of knee space as well as a that long flat roof stopping you from giving yourself a haircut. 

Each of the front seats has a fold down airline-style tray table, which kids go absolutely wild for.

The third row is really an occasional use only proposition, but it does the job and is reasonably easy to access. The middle row also slides forward (60/40 split) to allow a bit more space for the third row, which is nice.

The 5008 has a trick up its sleeve - removable third-row seats. If you fold the middle row down and remove the back row, you have a massive 2150 litres (VDA) of cargo volume. 

If you just fold the third row away you still have a formidable 2042 litres. Whip the back row out again but leave the centre row in place and you have a 1060-litre boot, reattach them and it's a still impressive 952 litres. So, it's a massive boot.

The 5008 is rated to tow 1350kg (petrol) or 1800kg (diesel) with a braked trailer, or 600kg (petrol) and 750kg (diesel) without brakes.

Peugeot's local arm is pitching the 5008 at an interesting point. While nowhere near the largest of seven-seaters, it is also not the cheapest, that honour going to Peugeot's former technical partner for SUVs, Mitsubishi. 

There is now just one specification level (although it isn't really), the GT and you can have it in petrol form for (deep breath) $51,990, or diesel form (keep drawing that long breath) $59,990. That's a lot of cash.

But as I say, the spec is not the same between the two. And there is a lot of stuff.

The petrol GT opens with 18-inch wheels, a 12.3-inch digital dashboard (upgraded, apparently), a new 10.0-inch touchscreen (ditto), front and rear parking sensors, around-view cameras, leather and Alcantara seats, keyless entry and start, auto parking, adaptive cruise control, powered tailgate, rear window blinds, auto LED headlights, auto wipers and a space-saver spare.

The more expensive diesel picks up the diesel engine (obviously), a banging Focal-branded 10-speaker stereo, acoustic laminated front side windows and 19-inch alloys. 

The diesel GT's front seats are also upgraded, with extra adjustability, a massage function, heating, memory function and electrical operation of just about everything on them.

Both versions have the new 10.0-inch multimedia touchscreen. The older screen was slow and really needed a good stab to work, which is a bit of a problem when so many functions are packed into the system. 

The new one is better, but still a touch laggy. Weirdly, the climate control shortcuts permanently frame the screen, so the extra real estate goes on those controls.

The diesel GT's seats are available as an option on the petrol as part of a $3590 option pack. The pack also adds the Nappa leather, which itself is a separate option for $2590 on that upper-spec model. Neither pack is cheap (but the Nappa leather is lovely) and the massage seats are more than a novelty.

Other option costs are $1990 for a sunroof and $2590 for Nappa leather (diesel only).

Just one paint colour, 'Sunset Copper', is free. The rest are extra. For $690 you can choose 'Celebes Blue', 'Nera Black', 'Artense Grey', or 'Platinum Grey.' 'Ultimate Red' and 'Pearl White' cost $1050.

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.

As the names of the cars suggest, there is a petrol and diesel engine. Both drive the front wheels only through automatic transmissions.

The petrol is a 1.6-litre four-cylinder turbo, with 121kW at 6000rpm and 240Nm from 1400rpm. The petrol scores a six-speed automatic and will cover the 0-100km/h run in 10.5 seconds.

For torque monsters, the diesel is the go, with 131kW at 3750rpm and 400Nm from 2000rpm. This engine scores two more gears for a total of eight and will run from 0-100km/h in 10.2 seconds. 

So neither of them are drag racers, which is to be expected when you've got a fair chunk of weight to pull (1473kg for the petrol, 1575kg for the diesel).

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.

Peugeot says the combined cycle figure for the petrol is 7.0L/100km and 5.0L/100km for the diesel. The petrol figure seems sort of likely, the diesel, not so sure.

I ran the lighter 3008 for six months with the same engine (but with two fewer gears, granted) and it averaged closer to 8.0L/100km. The last time I had the 5008 I got 9.3L/100km.

As I drove these cars on the launch event (mostly highway running), the dash-indicated 7.5L/100km figure I saw is not a reliable indicator of real-world consumption. 

Both tanks hold 56 litres, so based on the official figures, you'll cover around 800km in the petrol and over 1000km in the diesel. Bank on a day-to-day range about 150km lower than that.

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.

Once you're comfortable with the i-Cockpit, which features a high dashboard and a tiny, squared-off steering wheel, you'll feel like you're driving a much smaller car. 

I have theorised over the years that the light steering coupled with the small steering wheel makes it feel more dynamic than it is, but I think that's wrong - it's genuinely well set-up and is a car in which you can have some fun.

I was only able to drive the 1.6-litre petrol with six-speed auto on launch and that was on a horrifically wet day during Sydney's recent deluge. 

The M5 motorway was covered in standing water and the spray from the big rigs made driving conditions rather more difficult than usual. 

The 5008 sailed through it all (pun intended). That engine is hardly the last word in power and torque, but it does the job and the auto is well-calibrated to the numbers. 

The big Michelin tyres bite the tarmac pretty well and while you always feel the weight of a seven-seater SUV, it drives much more like a raised wagon than a doughy SUV. 

Fewer of its rivals are doughy these days, but there's a little bit of spark in the 5008, matching the promise of its looks. 

It's not quick, and it's not a hot SUV, but every time I get in this or its smaller 3008 sibling I ask myself why more people don't buy them.

It's irritating that the diesel costs so much more if you want that extra in-gear performance and another two gears.

The 5008 lands with six airbags, ABS, various stability, traction and braking systems, speed limit sign recognition, driver attention detection, distance warning, lane keep assist, lane departure warning, road edge detection, auto high beam, reversing camera and around-view cameras.

The diesel picks up lane positioning assist while none of them have reverse cross-traffic alert. Equally annoying is the fact that the curtain airbags don't reach to the back row.

The forward AEB includes low light cyclist and pedestrian detection between 5.0km/h and 140km/h, which is impressive. 

There are three ISOFIX and three top-tether mounts in the middle row and two top-tether restraints in the removable third row.

The 5008 scored a maximum five ANCAP stars in 2017.

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.

Peugeot's five year/unlimited kilometre warranty is now pretty standard but always welcome. You also five years of roadside assist and five years/100,000km of fixed price servicing.

Interestingly, the service prices aren't much different between the petrol and diesel, with the former costing $2803 over five years ($560 per year on average) and $2841 for the latter ($568.20 per year on average). 

You have to visit your Peugeot dealer once every 12 months/20,000km, which isn't too bad. Some turbo-engined cars in this segment demand more visits or won't cover as many kilometres between services.
