Mercedes-Benz GLE-Class vs Kia Niro

What's the difference?

If you can get past the relatively steep asking price, the design appeals to you, and its slightly last-gen ergonomics work for you, then there’s a lot to like about the GLE. It’s a big, capable and comfortable cruiser, but given there are cheaper and more efficient options around, it would be a decision of the heart rather than the head.

The Kia Niro S Electric is a solid little SUV that has decent space inside and some nice specs, but it's more expensive than its nearest rivals. The EV powertrain can take a little getting used to and I would have liked a smoother ride, but the 460km driving range is good.

For first-time EV owners, this wouldn’t be a bad option if you wanted to dip your toes in the water but it will suit urban dwellers and smaller families, like mine, best. This gets a 7.5/10 from me.

My son wasn’t in love with this one. Not enough buttons for him to press and he did comment on how bumpy the ride was in the back. He gives it a 6.0/10.

The GLE hasn’t changed massively since 2019, but sleeker lights and some tweaks around the face have helped it age relatively gracefully. As much as a 2.4-tonne SUV can be graceful.

There are still references to the original ML-Class the GLE succeeded, like the ‘coupe’ shape of the C-pillar that betrays the true SUV shape of the GLE.

The reshaped front-end has less black plastic on show, and its grille stays true to the pre-facelift design.

Inside, it’s just the steering wheel that’s new, everything else holds up well in terms of a design that’s also practical, though some would say it looks outdated given the many physical controls.

It’s a compact SUV with a footprint that's 4420mm long, 1825mm wide and 1570mm tall. But while small, I wouldn’t call it cute. It’s boxier than its sibling and without any of the swoopy design elements that make the EV6 look cool. 

I do like the way the two-tone body panelling, which is seen most prominently on the C-pillar, breaks up the ‘blocky-ness’ and creates areas of interest. As do the high-mounted rear LED lights. 

Speaking of lights, the base model makes do with halogen headlights, which unfortunately stand out against the LED daytime-running lights. You’ll notice the dimmer light at night, too.

The 17-inch alloy wheels are thick for better aerodynamics but the clever two-tone colouring stops them from looking unfashionable.

The interior has a lot style cred with the curvature of the door panelling blending in almost seamlessly with the dashboard.

The gently sloping panelling that houses the multimedia systems and switchable touchscreen interface for the controls creates a very pleasing cabin space.

There are some harder plastics mixed in here but enough soft touchpoints that you won’t be bothered by them. 

The GLE is very easy to use because of those physical controls.

Save for the trackpad in the centre console that can be used like a laptop’s control mat - it’s a little fiddly - everything is easy to locate and adjust and the controls feel nice. The switches along the climate control row all feel nice and clicky, buttons in the centre console are big and obvious, and even the steering wheel’s haptic buttons are laid out sensibly.

The touchscreen’s software has been updated since launch during the facelift and it’s easy to navigate, but wireless Android Auto or Apple CarPlay are a good workaround.

The front seats, as well as being comfortable, are adjustable to an impressive degree for finding your driving position and there’s plenty of room and light to make the cockpit feel airy.

Storage isn’t at a premium, there’s plenty of space in door cards, the central storage bin, and the cupholders and phone charger can be hidden away.

Behind the front row, rear seat space is ample, though if you opt for seven seats the second row can be moved to accommodate a third row of passengers when needed.

In our test car, that isn’t the case, so the GLE’s cavernous 630 litres of boot storage is available. The second row can split 40/20/40, which is convenient for loading long items while four passengers are present.

Oh, but under the boot floor, despite some extra room for bits and pieces, no spare tyre. Big marks down for a car that absolutely has the space for one.

It’s surprisingly roomy inside and all passengers will enjoy decent leg and headroom, but taller passengers will find the backseat cosier than the front.

As such, two child seats will fit best but you do have ISOFIX child seat mounts on the outboard positions and three top-tether points, if you need them.

The synthetic leather/cloth seat trim cleans well and is nice to touch. The seats themselves, front and rear, are well-padded and super comfortable.

The backs of the front seats can double as coat hangers and have hardened kickplates, which are always practical for little feet.

The front row gets the most amenities and tech. The 8.0-inch touchscreen multimedia system has clear graphics but is different to other Kia’s I’ve sampled recently. It seems to have been simplified but you’ll get used to it quickly.

There are plenty of charging options available, too, with a USB-A and C port, plus a 12-volt socket. Not needing a cable for the wireless Apple CarPlay is a bonus, too!

The front row also has the most storage space with two retractable cupholders, dedicated phone tray, glove box, middle console and skinny drink bottle holders in each door.

Back seat passengers enjoy two USB-C ports, reading lights, drink bottle holders in each door plus an armrest with two cupholders. As well as, a standard three-pin socket in case you need to run electrical gear or charge anything up on the go.

The windows are wide and offer good visibility but I really like the 150mm ground clearance. It was super easy for my six-year old to climb in and out, plus he got a good view this week!

The boot is good for this size SUV with 475L of capacity available. It does look more like a hatchback, because while you can readjust the floor to sit lower, the back still slopes up.

However, it was fine for my weekly grocery and school run. The 'frunk' storage is small at 20L, which is just big enough for a charging cable.

You don’t get a spare wheel but you do get a puncture repair kit. And being the base model, it’s not a powered tailgate but it’s not heavy to close.

There are two variants for the Niro, our base model, the S, and the range-topper GT-Line.

Despite being the base model, the Niro S will still set you back $65,300, before on-road costs. Which makes it about $5K dearer than the equivalent Kona Electric, and $20K more expensive than the ZS EV.

There is a hybrid Niro (also available in two grades), if you’re not quite ready to commit to a full EV life. The price isn’t as eye-watering, either, being just $44,380, before on-road costs.

The Niro is well-specified, though, and the driver will enjoy an electric seat with adjustable lumbar support while the passenger side remains manual.

The regenerative braking is customisable (levels 0-3), there’s an 'iPedal' function, a dual-zone climate system, reversing camera and the backs of the front seats even double as coat hangers.

The tech is also good, with an 8.0-inch touchscreen multimedia system, 10.25-inch digital instrument panel plus wireless Apple CarPlay and wired Android Auto all coming as standard equipment. More on the tech below.

The GLE 450d’s 3.0-litre inline six-cylinder diesel engine is turbocharged, with a healthy 270kW and a brawny 750Nm to its name. That torque peaks all the way from 1350rpm to 2800rpm, by the way. Handy.

A nine-speed automatic transmission sends drive to all four wheels ('4Matic' in Merc-talk), while a 48-volt ‘mild-hybrid' system ('EQ Boost' in Merc-talk) means take-offs and shifts are aided by a bit of electric power.

Mercedes says the GLE can dispatch the 0-100km/h sprint in just 5.6 seconds, and that feels about right.

The Niro is a full EV and has a front-wheel drive drivetrain with a maximum output of 150kW/255Nm. It’s not as powerful as its stablemate and only has the single-motor which is powered by a 64.8kWh lithium-ion battery but going from 0-100km/h can still be achieved in 7.8 seconds. With specs like those, this is most suited for an urban setting.

Mercedes claims a 7.4L/100km combined cycle (urban/extra-urban) fuel consumption figure for the big lug, but achieving that and making the most of its large 85-litre tank is a challenge.

We averaged 8.7L/100km on test but the trip computer showed as low as 8.0L/100km at one point. Get the GLE on the highway and fuel use plummets.

Theoretically you should be able to get about 1150km from a single tank, but realistically we wouldn’t plan trips any longer than 900km between fuel stations. 

Still impressive, given that’s about the distance between Melbourne and Sydney, or Sydney and Brisbane. Roughly.

Such is the EV life but you can’t escape the charging.

The onboard DC charger has up to 85kW of capacity and that means on a 50kW fast charger station, you can get from 10 to 80 per cent in 65 minutes.

However, if plugged into a 350kW ultra-fast charger, you’ll only save 22 minutes because it can’t accept that faster speed.

On a 7.5kW system, you’ll go from 10 to 80 per cent in approximately nine hours, 25 minutes. On an 11kW, you’ll see that figure drop to six hours, 20 minutes.

The charging port is a Type 2 (CCS Combo2) and the car comes with an emergency charging cable that can plug into a standard three-pin domestic socket, if needed.

However, it’s slow going and you’re looking at a wait time of up to 27 hours, 30 minutes to get to a full charge. All other cables cost extra.

The official kWh/100km consumption is 16.2kWh and my average on-test figure was 14.3kWh after a mix of urban and open-road driving.

However, I did see figures getting closer to 20kWh on longer trips. Still, I would consider my average to be efficient.

The Niro S has a driving range of up to 460km (WLTP).

A trip in the GLE feels like a welcome step back in time. Sure, coming in close to five metres long and two-and-a-half tonnes means it’s not a nimble steer, but the GLE strikes a nice balance of comfort and tactility that’s getting rarer.

None of it feels particularly sharp in terms of inputs or feedback, but it’s easy and predictable to a point where even winding back-roads are effortless to flow through.

The big diesel engine feels almost lazy, but it’s just so effortless in getting things moving as it strives to sit close to idle whenever possible. Because of that, there’s little noise from the engine bay even under reasonable acceleration, and the powertrain is helped by that 48-volt system which makes stop-starts from the lights super-smooth.

The mild-hybrid also helps smooth out power delivery, to the point where the only time the GLE feels clunky is the occasional lag when shifting from Drive to Reverse or vice versa.

The test car’s suspension isn’t the optional airbag set-up, but the non-adaptive steel does fine in terms of comfort and soaking up harsh surfaces. And even the big 21-inch wheels aren’t too bad over sharp bumps.

With smaller wheels (more tyre cushioning) and the air suspension, it feels like the GLE would ride gorgeously.

Its body control is predictable on smooth roads, and if you’re careful you steer the hefty SUV through tight, winding roads easily, but consistently rough surfaces can make the GLE feel unsettled for a short period of time.

There’s an overall softness to it that means gentle off-roading is possible, and the tyres are thick enough to make it comfortable. You won’t find yourself being tossed around on a flat enough gravel road.

This is a pretty simple car to drive but it doesn’t feel as fun as some other EVs I’ve driven. It can even feel sluggish when you accelerate from a full stop and that makes it feel laggy in stop/start traffic.

Once you’re on your way, the acceleration is fairly responsive. You feel confident overtaking on the open road, too.

The car feels connected to the road with minimal shuddering through the steering wheel. The car responds in a timely manner when you have to make sudden moves, which I like.

Sometimes, the lane keeping aids make it feel jerky and I turned it off in some situations.

The regen braking delivers a big physical presence like the EV6 but isn’t as refined and can feel almost ‘bunny hoppy’ at times.

You can customise it up to four levels, zero being low regen and four being the iPedal. I’m not overly fond of the iPedal, so didn’t use it that much this week and kept it at level 3.

You do have to change up how you drive an EV, so this wasn’t that surprising and something I’m sure you’d get used to.

The ride comfort is pretty mixed. Around town, it’s good but there’s quite a bit of passenger movement in this. You kinda feel like you’re bobbing along sometimes, which is jolting.

You also feel the road but the seats are so comfortable, they stop it from feeling too rough. 

Surprisingly, the cabin gets very loud with wind and road noise. You can still chat but you won’t forget that it’s there, which is a shame.

I didn’t notice much difference between the drive modes, so it was kept on 'Normal', too. 

This is very easy to park! It’s a good size for even a tight car park with a 10.6m turning circle and the reversing camera is super clear, which is great. 

However, I would have liked to have seen front parking sensors, as well as the rear sensors. You can get them on the GT-line though.

The Niro EV S has a good list of safety features, with the following being standard: LED daytime running lights, lane departure alert, lane keeping aid, blind-spot monitoring, rear cross-traffic alert, a reversing camera (with dynamic guidelines), rear parking sensors, driver fatigue alert, check rear occupant alert and adaptive cruise control (with stop/go function).

It has auto emergency braking with car, pedestrian and cyclist detection as well as junction turning assist, which is operational from 5.0-85km/h. 

The Niro was recently awarded a maximum five-star ANCAP safety rating in 2022. It has eight airbags and that does include the newer front centre airbag.

There are ISOFIX child seat mounts on the rear outboard seats and three top tethers, but two seats will fit best. And while there will be room for a 0-4 rearward facing child seat, it will encroach on front passenger comfort.

Servicing isn’t cheap at Mercedes, even in the context of this market segment. A three-year service plan for the GLE costs $4045, while five years is $8055. That’s $1348 or $1611 per service respectively. The later services in those five years will of course be much more expensive and bring the average up.

Intervals are every 12 months or 25,000km, but Mercedes’ five-year/unlimited-kilometre warranty means anything major that goes wrong in that time should be covered - always read the fine print.

The brand’s Australian website lists 67 Mercedes-Benz dealers that can service your car.

The ongoing costs are great on the Niro. It comes with Kia’s ‘better-than-average-for-the-market’ seven-year/150,000km warranty, which also covers the battery.

You get a seven-year capped-price servicing plan and services average $250 per year, which is good.

Servicing intervals are more in line with a petrol car at every 12 months or 15,000km. It’s usual to see those intervals doubled on an EV but it’s still reasonable.
