Peugeot 408 vs Kia K4

What's the difference?

The Peugeot 408 GT Hybrid delivers heaps of standard equipment and safety tech for what is now a much more competitive price. It’s also super fuel-efficient, which is right for these turbulent times, offers thoughtful practicality and the wagon-fastback-crossover-SUV look is striking. The price paid for miserly economy is a peaky small-engine powertrain and the ownership promise isn’t exactly class-leading. That said, it deserves consideration in its new, even more competitive under $60K mid-size SUV segment.

The new Kia K4 GT-Line has a lot to offer - an interesting design, lots of features and a pleasant driving experience. It’s not without its quirks and there are times when a more powerful engine may have improved it for me as a long-term prospect as I do some big kays every year but it ticks the boxes as a friendly urban dweller.

Peugeot Design Director Matthias Hossann has been guiding the brand’s look and feel since 2020 and the result is a recognisable approach across the range with enough flexibility to give each model its own personality.

Recurring themes include the dramatic, fan-like grille with body-colour elements, narrow angled LED daytime running lights (DRLs) slicing through the outer edges of the nose and sinister tapered headlights set into the front corners.

The rear end maintains the visual drama with a stacked, angular treatment sectioning off the ‘Claw Effect’ LED tail-lights (the Peugeot brand mark is a Lion), chamfered mid-section and chunky bumper.

And among what increasingly feels like a mass of same-same newcomers the 408’s sloping turret and high, wide haunches give the car a distinctively sporty fastback look.

The interior is classy and clean although the almost uniformly grey colour palette is unrelenting.

The two-tier dash adds visual interest and a combination of sweeping curves and clean, straight lines around the cabin lift the tone. Nappa leather trim with the ribbed seat centre panels using perforated hide also looks classy.

But then we come to the ‘iCockpit’ instrument display and steering wheel combination. It’s based on the idea that reducing the size of the steering wheel and lowering its position while flattening its top and raising the location of the instrument binnacle is a better solution than the traditional look-through-the-steering wheel approach.

It doesn’t work for everyone and it doesn’t work for me. As noted in previous Peugeot reviews, after more than a decade in existence various members of the CarsGuide editorial staff continue to struggle with the arrangement, while others love it. 

For me, the wheel feels too low, yet the top of it obscures the lower part of the instrument panel. While it may work well for others I see it as the answer to a question no one was asking.

Have to admit I wasn’t convinced on the design of this new sedan at first as it can look a little out of sorts from certain angles. But the more time I spend with it, the more I appreciate its sharp lines and sporty rear shaping.

The small sedan market doesn't have a lot of options now because SUVs are so popular but it's nice to see a design that stands out and the fang-like LED light design at the front and rear, as well as the 18-inch alloy wheels make the K4 look very cool.

The rear doors look sleek because the handle has been hidden in the C-pillar and the K4 is particularly striking in our test model's 'Wave Blue' ($600 RRP) paint colour.

Head inside and you'll find a cabin that looks slick with a two-tone synthetic leather upholstery that feels supple underhand and a plethora of soft touchpoints under all the bits that touch.

The black headliner creates a posh space but the sunroof helps the cabin to feel airy when you need it to.

The dashboard isn't too wide, preferring a sharply linear shape and is headlined by a massive display panel that houses dual 12.3-inch screens and a 5.0-inch climate panel.

There is still a strong presence of plastics inside but you don’t tend to focus on them.

Unlike some other new cars hitting our market, the K4 hasn’t done away with its buttons and dials - and there’s enough to satisfy those who don’t like to rely on a screen for everything. The extra traditional element of the physical gear selector adds to its charm as well. 

At close to 4.7m long, around 1.9m wide and a bit less than 1.5m tall with a 2790mm wheelbase, the 408 sits in the middle of the typical mid-size five-seater footprint.

Ample room in the front, although the lower section of the two-tier dash protrudes a fair way towards the driver and front passenger and the centre console is broad so it feels snug rather than airy.

Storage includes generous door bins with room for larger bottles, a lidded (and illuminated) bin between the seats that doubles as a centre armrest, two cupholders in the console with an oddments tray ahead of them and a decent glove box with an extra pocket built into the lid.

Switching to the rear, sitting behind the driver’s seat set for my 183cm position, there’s loads of leg- and headroom and enough width for three adults when required and more than enough for a trio of up to mid-teenage kids. Centre rear is less of a short-straw position, too, thanks to a relatively low and flat central tunnel.

The lack of a fold-down rear centre armrest is a miss mainly because it means there are no cupholders in the rear. But there are decent door bins with a space for smaller bottles, netted map pockets on the front seatbacks and a storage cubby at the back of the front centre console.

Speaking of which, individual air vents in the back of that console are a welcome addition.

 The boot is large for the class at 508 litres (VDA) with the rear seat upright and 1583 litres with the 60/40 split-folding backrest folded down. The power tailgate (with foot sensor and pedestrian detection) also makes life easier.

Other thoughtful touches include four load tie-down anchors, a netted pocket on the right-hand side, elasticised straps on the left-hand side, specific lighting and a pair of bag hooks.

Power and connectivity options include two USB-C sockets, a 12-volt outlet and a wireless phone charging pad in the front, another two USB-Cs in the back and a second 12V plug in the boot. So no problems with charging capacity for phones and other devices.

Maximum braked trailer towing capacity is a useful 1300kg (750kg unbraked) but we have to put a big black mark against provision of a repair/inflator kit rather than a physical spare. Not good enough for the Aussie market. 

The K4 feels big for the class, especially compared to its nearest rivals and that translates to a cabin that feels adult-friendly in both rows. An impressive feat for a small sedan.

Access is the only time you will have moments of 'I should have opted for an SUV'. That's because you will get in your daily squats sliding in and out of the K4 due to its 140mm ground clearance.

The rear doors also feature a wide wing that juts out from the door handle and it catches your hip almost every time you go to close the door.

The wide front seats offer lots of comfort with thick padding and long under-thigh-support. The driver's side is powered with adjustable lumbar support but the passenger seat only offers manual adjustments, which is surprising for a top-grade model. However, both front seats enjoy heat and ventilation functions.

The back bench seat offers similar comfort to the front with seat padding and length but it's not terribly wide and two adults (or child car seats) will fit best.

Amenities and storage is decent for the class with each row enjoying four drink holders and two USB-C ports. Front rowers also get a wireless charging pad and 12-volt socket.

In the front there is a large glove box that fits more than just an owner's manual, a mid-size middle console and a centre console that features retractable cupholders to open up the space if you need to. A dedicated phone cradle with small spaces on each side rounds up individual storage for the front.

In the rear there are two map pockets, a small item cubby next to the USB-C ports and a pair of directional air vents, reading lights and a fold-down armrest.

The boot space is massive for the class at 508L (that's nearing mid-size SUV territory) but the aperture is narrow and I couldn't fit my big booster seat through the opening.

The boot is quite deep as well and you may find yourself climbing into it to retrieve items that roll into the back.

The rear bench seat has a 60/40 split which can help with storage and there is a temporary spare tyre underneath the floor.

While you don't get a powered tailgate in this model, the lid isn't heavy to operate and has a proximity opening function that keeps it practical when you have your hands full.

This just means when you approach and stay near the boot with the key fob on your person the boot lid will pop open for you.

The 12.3-inch touchscreen multimedia system looks great with crisp graphics and a responsive touchscreen. The menus are in an easy-to-understand layout which you'll get accustomed to in no time. The 5.0-inch climate display sits to the right of this system and it's nice to have it on display all the time.

The 12.3-inch digital instrument cluster isn't all that customisable but it's easy to read with large text and a small menu screen that shows nav directions, trip info or a compass.

The built-in satellite navigation system is easy to get going and to cancel a route guidance, it's a one button affair which is great for when you're on the go.

The system features wired and wireless Apple CarPlay and Android Auto. The CarPlay is simple to connect to and retained a steady connection this week with feedback from my callers that my voice was clear on calls.

The new K4 sedan is offered in four grades - the base-model S which has an optional 'Safety Pack' available, the mid-spec Sport and Sport+ grades and the flagship GT-Line, which is the model on test for this review.

The GT-Line is sharply priced at $42,990, before on road costs. This positions it in the middle of its small sedan rivals, the Hyundai i30 N Line Premium ($41,500 MSRP) and the Mazda3 Astina ($43,310 MSRP).

What the K4 GT-Line has going for it over its peers is a standard specification list that features some heavy-hitting technology.

This includes dual 12.3-inch displays, a 5.0-inch climate display, built-in satellite navigation with 10-years' of map updates, wireless/wired Apple CarPlay and Android Auto and dual-zone climate control.

Charging is taken care of by two USB-C ports for each row but the front row also enjoys a 12-volt socket and fast wireless charging pad in the dedicated phone cradle.

There's also an eight-speaker Harman Kardon sound system, over-the-air updates, digital radio, AM/FM radio, Bluetooth connectivity, and a 'Sounds of Nature' soundscape for added ambience.

The Kia Connect app is also included and this allows user access to the emergency call functionality (e-Call), remote control functions for the vehicle, as well as vehicle status monitoring.

Premium equipment includes a tilt and slide sunroof with electric sunshade, two-tone synthetic leather upholstery, heated and ventilated front seats, an electric drivers seat (with two-position memory function and adjustable lumbar support) and a heated steering wheel.

For a small sedan, it comes packed with features!

The Peugeot 408 Hybrid is powered by a 1.2-litre, turbo-petrol, three-cylinder engine producing 100kW at 5500rpm and 230Nm at 1750rpm.

This compact, all-alloy, direct-injection unit works in concert with a single 15.6kW/51Nm 48-volt electric motor integrated into the six-speed dual-clutch auto transmission and energised by a 0.9kWh lithium-ion battery.

Drive goes to the front wheels only and Peugeot claims a 0-100kmh sprint time of 9.4 seconds.

The flagship grade is front-wheel drive and has a 1.6-litre four-cylinder, turbo-petrol engine that produces up to 142kW of power and 265Nm of torque giving this a more powerful presence than its non-turbo siblings (which only produce up to 112kW/192Nm).

However, while the power is adequate for the GT-Line there are times when the engine sounds like it's working a bit too hard.

The eight-speed torque-converter automatic transmission can also become flustered as it moves through the lower gears, especially when you’re accelerating quickly.

On the whole, the power delivery and outputs are more than enough for a city environment and the odd road trip.

The 408 Hybrid’s official fuel consumption figure for the combined (urban/extra-urban) cycle is 4.5L/100km, the 1.2L turbo triple emitting 102g/km of CO2 in the process.

And it’s important to point out those official (ADR 81/02) numbers for the 408’s consumption and emissions are better than any of the direct competitors we’ve called out in the ‘Price & Features’ section above. 

Over a week of mainly city and suburban running with some freeway sections thrown in, we recorded an on-test average of 6.0L/100km. Impressive for a mid-size crossover weighing in at a bit over 1.4 tonnes.

Brim the 52-litre tank with minimum 95 RON premium fuel (ethanol blends not recommended) and using our real-world figure you can expect a handy driving range in excess of 860km.

With an official combined (urban/extra-urban) cycle fuel usage figure of 6.7L/100km and a fuel tank size of 47L, this model has a theoretical driving range of 701km. That does sit around 80 kays less than some of its rivals but it’s still sufficient for those wanting to do the odd road trip!

My on-test fuel usage has popped out at 9.2L/100km, which is based on figures achieved at the pump (32.05L) and my km travelled (348km).

I’ve done mostly urban trips this week with one longer open-road drive and overall I’m not too surprised by that figure because I’ve been pushing it hard but it could be better.

The K4 is a simple gal because Kia recommends a minimum 91 RON unleaded petrol to be used for all models.

Even with the assistance of an electric motor in the transmission and a turbo on the engine, a 1.2-litre, petrol three-cylinder powering a more than 1.4-tonne five-seat car is always going to be an interesting equation.

And in practice, although the small triple’s peak torque (230Nm) is available from just 1750rpm it lacks the smoothness of larger capacity mild- and full-hybrid combinations. Especially at slower speeds, the powertrain feels relatively edgy and agitated.

Outright acceleration is fine (claimed 0-100km/h acceleration is 9.4sec) with decent mid-range pulling power for confident overtaking or decisive lane changing (a 15.6kW/51Nm boost from the motor playing its part) and the dual-clutch auto is a more polished example of what can be a fractious device. 

But engineering and tuning for maximum fuel-efficiency has an impact on driveability. For example, we noticed the air-conditioning system’s output softened at standstill, which led to some mild window fogging in stop-start traffic on a particularly humid morning. Haven’t seen that for a while. 

The strut front, torsion beam rear suspension delivers a compliant ride and responsive handling in classic Peugeot fashion. The steering in particular points accurately and provides good road feel. 

We’ve covered the intricacies of the i-Cockpit instrument and steering wheel configuration in the Design section as its shortcomings (for me, anyway) are more ergonomic than dynamic.  

The car is relatively quiet, thanks in part to sound-dampening acoustic glass and the Michelin e.Primacy tyres (205/55) which also grip persistently if you decide to slice through your favourite set of corners. Push the engine harder and it’s revvy note and exhaust rasp will start to make their presence felt. 

Regenerative braking is helpful and the physical brakes (ventilated discs and the front and solid rotors at the rear) are nice and progressive.

The front seats are firmer than the Peugeot norm but remain comfy enough and they provide enough side support to keep you well located. 

Despite the swoopy fastback design, all-around vision is surprisingly good and an overall length under 4.7m, an acceptable 11.2m turning circle, a clear reversing camera and a 360-degree camera view make parking straightforward. 

As mentioned earlier, the power is adequate to move this car around on the open-road but you have to be a little aggressive on hills to keep your speed consistent.

It’s not always quick off the mark, though, and you’ll notice that when you have to cross traffic or enter a roundabout - so allow for extra car lengths. Once you get going, it’s responsive in the city.

The steering is sports-stiff and so is the suspension. This makes the handling feel nimble in turns and sure-footed when doing quick lane changes but you hear and feel every bump in the road. 

On-road comfort is okay around the city but the road noise is very loud inside the cabin and is particularly noticeable at higher speeds. You’ll have to raise your voice to chat to passengers in the back when you're on the highway.

The K4 has a small turning circle of just 10.7m and you can easily do a U-turn in spaces that others might have to do a three-pointer. This made the K4 feel friendly in small car parks and on ramps.

The direct steering makes it easy-enough to park, as does the reversing camera and front/rear parking sensors but I’m pretty disappointed that at the top grade-level, you miss out on a 360-degree camera system (tsk, tsk, Kia).

The Kia K4 has just been launched and hasn’t been tested by ANCAP yet, so is unrated but Kia is hustling to get it tested so it can join in on their strong five-star performance record. The K4 has seven airbags, including a front centre airbag.

The K4 GT-Line has all of the bells and whistles when it comes to safety equipment and includes the big-ticket items like blind-spot monitoring and collision avoidance, intelligent seatbelt warning (all seats), rear cross-traffic alert, front cross-traffic alert, lane keeping aid, lane departure alert, leading vehicle alert, emergency call functionality, side exit warning, rear occupant alert, traffic sign recognition, driver monitoring and alert, LED DRLs, dusk-sensing LED headlights, front/rear parking sensors and a reversing camera with dynamic guidelines.

The K4 GT-Line has AEB with forward collision warning, car, pedestrian, cyclist, and junction crossing detection.

The rear seat has two ISOFIX child seat mounts on the outboard positions and three top tether anchor points but two seats will fit best.

Kia has become well-known for having annoying sound alerts in their cars and while the K4 has them too - you can easily disable the most annoying one, the traffic sign recognition, by holding the steering wheel volume button in for a few seconds.

Peugeot covers the 408 with a five-year/unlimited kilometre warranty, which is perilously close to sub-par in 2026 with an increasing number of brands at seven, eight and up to 10 years conditional. The battery warranty at eight years/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/15,000km and pre-paid servicing is offered across three-, four- or five-year plans, with the latter at $2070.

That’s a not insubstantial average of $414 per workshop visit, which Peugeot says will save you $893 compared to pay-as-you-go over the five years.

For reference, a Toyota RAV Hybrid service for any of the first five years is $260, although pricing steps up after that period.

Peugeot has a well established network of 31 dealers mainly covering major cities and key rural areas, primarily on the east coast. Currently, no presence in Tassie or the Northern Territory, while Perth and Adelaide are the only representation in WA and SA. 

The K4 GT-Line is offered with Kia’s seven-year/unlimited-kilometre warranty. That’s a pretty good term for the class and there is a seven-year capped price servicing program for a flat $3877 (averaging $554 per service), which is slightly more expensive than others in the class.

Servicing intervals could get annoying if you do big kays every year as they're spaced at every 12 months or 10,000km, whichever occurs first.
