Kia Picanto vs Mercedes-Benz Gls450

What's the difference?

Australians are moving into ever-larger vehicles when really we should be embracing the small car now more than ever. It's great Kia is still here, with its Picanto showing what can be offered in such a compact form-factor.

While it's not as affordable as it once was, it looks like it won't be long before Kia is the last torchbearer of sub-$20k starter cars. Even so, this is a great choice for buyers on strict budgets.

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

You wouldn't know it in Australia, where our collective tastes are orienting toward larger and larger vehicles, but city cars are experiencing something of a golden age overseas.

Cars like the Nissan Sakura, Honda N One, and Hyundai Casper join a long list of others which are design leaders in the city-car segment, and this is why the Picanto needs to look sharper than ever to compete.

Particularly in the GT-Line form we tested for this review, the 2024 car has adopted a dramatic facelift which complies to Kia's incoming and much more science-fiction look, complete with an extremely angular design and frowny LED light fittings.

Around the rear, there's a reworked set of tail-lights with a contemporary strip which almost reaches the whole way across the boot lid, and the new alloy wheels round out the whole aesthetic.

Given this, it's a little disappointing to see how few elements have changed on the interior. From the inside, this Picanto feels basically the same as the pre-update version.

I like the D-shaped steering wheel the GT now gets, and the multimedia screen is great for such a small and affordable car, but all the other switchgear, including the steering wheel is from previous-generation Kia products, and not the shiny new design-led stuff which appears in cars like the Sportage, Sorento, or Niro.

Also, while it's feature-laden all things considered, the interior plastics are mainly the harsh, hollow, scratchy kind. The new digital instrument cluster isn't one big screen, instead it's constructed of a few basic sectors which aren't customisable outside of the background colour. At least the central portion shows some useful information.

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

Feeling a little old or not, the Picanto has a clever interior which makes the most of its limited dimensions.

There are huge bottle holders in the front doors, a further two with little flip-out sectors which sit below the air-con controls. These holders can be folded away to turn this space into a tray for the storage of large objects. There's even a centre armrest console box, but it's tiny.

On the topic of air-conditioning controls, these are, refreshingly, physical dials, which are increasingly going missing as manufacturers move such functions to touchscreens. The Picanto keeps things manual though, even including a volume and tuning knob for the touchscreen, with physical shortcut buttons adorning the bottom section of the frame.

Physical controls is something Hyundai Group has committed to, and it's not until you use a vehicle without them you realise how essential they can be.

Despite its tiny footprint, there's also plenty of room in the cabin for an adult my size (I'm 182cm tall). I felt as though there was massive airspace between my head and the roof, as the Picanto's seats let you sit nice and low to the ground, and while it's limited in its width, it feels like I had enough room and adjustability for my legs.

Only one area brought me discomfort and it was the elbow-rest in the door. Sounds silly, but while the GT-Line has a little synthetic leather strip here, for some reason it has no padding, so it's seemingly for aesthetic purposes only and is still an uncomfortable place to rest your elbow on longer journeys.

It sounds unlikely, but I fit behind my own driving position in the back seat, with my knees almost up against the back of the front seat. Thankfully, the seat backings are softly-clad so even if you were slightly taller than me it might be ok.

Again, headroom is sufficient, and the seats are reasonably comfortable in the outer two positions. There are no amenities in the back seat. Rear passengers don't get air vents, door pockets, or a drop-down armrest in the centre position. There is only a small pocket on the back of the passenger seat. Can't say it would be the best space for longer journeys, but it fits adults for short city trips.

The boot measures 255 litres. It's small enough it may rule the Picanto out for some family buyers who need to wrestle with a pram or some such. The boot is large enough to fit either the largest CarsGuide luggage case on its own, or the two smaller ones, but absolutely not all three. It may surprise you to learn there is enough room under the floor for a space-saver spare wheel.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

This is another area where the Picanto is feeling in need of a little innovation. It has the same very dated 1.2-litre four-cylinder petrol engine as the previous car, producing a sufficient but not exciting 62kW/122Nm.

It drives the front wheels via an equally old four-speed automatic transmission, or as tested, a five-speed manual transmission.

It's better with the manual if you can drive one, and a bit of a win for first time or young buyers who will still have the option to learn to drive one, so points there.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

An older engine and transmission combination makes for a less than impressive fuel consumption figure in today's market, but then the Picanto is a very light car, so it has lower fuel consumption than most of its contemporaries regardless.

The official fuel consumption on the combined-cycle test of the five-speed manual we tested is 5.4L/100km, and in our week of what I would consider fairly combined usage our GT-Line drank 6.0L/100km. Not great when you consider a much larger hybrid Corolla can use less fuel, but pretty close to the claim nonetheless.

The Picanto has a 35-litre fuel tank – enabling a theoretical driving range of 648km – and happily drinks base-grade 91RON unleaded fuel.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

You've got low power, a pretty low-tech engine and transmission, but this little Kia is still great fun to drive.

For a start, you can have it as a manual that lets you wring the best out of the little engine, which is easygoing but lacklustre with the four-speed auto.

To be clear, it's not a great manual - usually when you get a brand new manual in 2024 it's one of those fancy performance ones with nice damping and notchy gates, but as simple as it is, it also gives the car a raw mechanical nature which keeps it engaging to drive. There are real consequences for choosing the wrong gear and it takes a touch of skill to get used to, a lost art of the all-encompassing drive which is a welcome change of pace compared to a lot of cars today.

The Picanto also has keen steering helping the organic feel, and it has a firm ride, too, which makes it surprisingly sporty in the corners, but it's lightweight nature and firm suspension gave it a crashy and bouncy feel on some of the inconsistent Sydney streets I exposed it to.

It's also a bit noisy in the cabin, both in terms of engine noise (you have to rev the thing to get it going) and tyre roar on anything but the finest tarmac. This issue increases with your speed, and reminds you of its city-car intention when you're on the freeway.

Still, the city is where it's best suited to, and it's a joy to easily dart down alleyways which take a degree of caution in the usual mid-size SUVs you see around the place, and the fact you can park it anywhere can be a real blessing.

The visibility is great, too, which means multi-lane situations aren't a nightmare, and the full suite of manual adjustment for the stereo and air conditioning are super easy to use when you're on the go (who has time to adjust a touchscreen when you have a manual transmission to worry about?)

In conclusion then, the Picanto isn't to be underestimated. This is a spritely fun little thing which makes the most of its limited hardware, but it truly is best suited for the confines of a city, and gets less impressive as you get it out on the open road.

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

Kia's stand-out seven-year/unlimited-kilometre warranty isn't as stand-out as it once was, but is still the standard to beat for this segment, and is especially impressive considering the up-front cost of the Picanto.

You also get seven years of roadside assist included and a seven-year capped-price servicing program.

Over those seven years the price averages out to $438 annually, which is not as cheap as it could be, especially considering many Toyotas cost about $250 a year to keep on the road for their (shorter) warranty period.

The Picanto needs to visit a workshop once every 12 months or 15,000km, whichever occurs first.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
