Mercedes-Benz EQ-Class vs Renault Koleos

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

To be fair to Renault, when the second-generation Koleos launched in 2016, it was a competitive offering. The problem is, a bunch of medium SUV rivals have been replaced in that time and some of them - Toyota RAV4, Kia Sportage, Mazda CX-5 and Hyundai Tucson, to name a few - are high-quality offerings with an engaging drive and the latest tech and in-car features.

Unfortunately, that leaves the Koleos towards the rear of the medium SUV pack.

It offers solid value-for-money, handles reasonably well and is still one the best-looking SUVs on the road. But beyond that, the Koleos can’t keep pace with those top-notch rivals.

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

An area that Renault has excelled at in the past decade has been exterior design. Under the stewardship of design chief Laurens van den Acker, Renault has transformed from somewhat quirky to modern and sleek.

The Koleos is getting on in years, having arrived in 2016, but it’s still a handsome SUV. A 2020 facelift sharpened its looks further and we reckon it’s one of the best-looking models in the medium-SUV segment.

Piano black inserts around the gear shifter are a nice touch, but the fake carbon-fibre inserts look and feel cheap. It’s all a bit generic.

But the appealing contrast yellow stitching on the seats, gear shifter housing, doors, centre armrest and more breaks up the grey with a little pop of colour.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

It might lack the up-to-date styling of those rivals, but the Koleos is practical and spacious inside and great for family duties.

As with the outgoing fourth-generation Nissan X-Trail, the Koleos is one of the larger offerings in the medium SUV segment, and it’s evident when sitting in the front or rear seating row.

Rearward visibility could be better, with a small rear screen and thick C- and D-pillars impeding vision and creating a blind spot.

The front seats are well supported and comfortable and while the driver’s side is power adjustable, the front passenger seat is manually adjustable.

It has a deep central storage bin with a hidden shelf for coins and more. The Koleos features a sizeable glovebox and good bottle storage in the doors, with room for other items.

There’s a weird fixed cup holder in the centre console. It’s not adjustable and there’s room for two very narrow cups and two larger, but not wide, cups. It’s strange. Interior designers could have used that space better.

The CVT's position indicators are located to the left of the shifter and are thus obscured, so you have to rely on the instrument cluster display to confirm what gear you want. 

The steering wheel looks and feels good, but the controls aren’t super logical. There are old school switches in the console to activate the cruise control and speed limiter, but then to adjust and reset the speed you have to hit buttons on the wheel that are not clearly marked. 

The audio controls are housed on a panel-like stalk to the right side of the steering column, which isn’t ideal. These make more sense if they’re housed on the wheel itself. 

Along with a number of cars we have sampled recently, the Koleos has split analogue and digital controls for the air conditioning. Just integrate it in the screen or have traditional controls - not both!

It has a part-digital instrument cluster which is fine, but there’s no head-up display.

Renault’s 'R-Link' multimedia set-up in the Koleos is old, with dated graphics and a small screen, but the menu layout is clear and logical. 

The Koleos lacks wireless phone charging and it makes do with wired Apple CarPlay and Android Auto. The quality of the Bluetooth and CarPlay phone audio is poor and sounds tinny. 

The proximity key that locks and unlocks the vehicle remotely when you walk towards or away from it works every single time. Many of these systems from other brands are patchy at best but the Renault system is faultless. 

The rear seats recline and fold manually 60/40. They’re also surprisingly comfortable. There’s enough bucketing to sink in a bit, and the seats are set high up so kids can easily see out windows.

Space is ample in the second row, with loads of head, leg, toe and knee room, even behind my six-foot (183cm) driving position.

The rear pew has ISOFIX points on the outboard seats, lower air vents, a 12-volt outlet, map pockets, a centre folding armrest with two cupholders, but no USB ports. You have to make do with the two ports at the front.

Open the power tailgate and you’ll find a decent 458-litre boot with all seats in place (maximum 1690L), which is off the pace of its cousin, the Nissan X-Trail (565L), as well as the Toyota RAV4 (580L) and Hyundai Tucson (539L).

A 17-inch steel spare wheel is housed under the boot floor which might explain the lower boot capacity, and there are handy tie-down hooks, a couple of smaller storage nooks and a solid cargo blind. 

A European badge doesn’t always mean you pay more than say, Korean or Japanese offerings, and Renault is an example of that.

The Koleos line-up, for now, starts from $33,590, before on-road costs, for the two-wheel drive Life and tops out at $46,390 for the Intens all-wheel drive.

But after July 1, 2022, prices will increase across the Renault line-up, with the Koleos set to range from $35,000 to $47,500.

There’s only one petrol engine option since the diesel was dropped in 2019 and each variant is paired with a continuously variable transmission (CVT) driving either the front or all four wheels.

That pre-July pricing is competitive against its rivals, undercutting the opening price of automatic versions of the Hyundai Tucson, Kia Sportage, Mazda CX-5, Mitsubishi Outlander, Subaru Forester, Toyota RAV4, and more.

Our test car, the Koleos Black Edition, is priced at $40,090 (rising to $40,500 from July 1) and is based on the specification of the mid-range Zen front-wheel drive (FWD). It is limited to 400 units in Australia.

Renault is one of a number of car makers to offer a black-themed model in recent times, alongside Kia, Mitsubishi, Toyota, SsangYong, and others.

The Black Edition adds dark flourishes like 19-inch dark-grey alloy wheels, gloss black roof rails and door mirrors, sidesteps, French flags on the B-pillar (even though it’s built in South Korea) and a choice of three exterior metallic paint colours including black (of course), grey or white. 

It also gets a hands-free powered tailgate, black synthetic leather upholstery with yellow stitching, matt carbon-look inserts, an 8.7-inch multimedia portrait touchscreen and ‘Limited’ badging on the chrome door sills.

That’s on top of features that are standard on the Zen, like a proximity key, push-button start, dusk-sensing headlights, rain-sensing wipers, auto-dimming rear-view mirror, auto-folding exterior mirrors, an electrically adjustable driver’s seat, heated front seats, a reclining rear seat, dual-zone air-conditioning, and heated and cooled front cupholder.

The multimedia system houses sat nav and comes with wired Apple CarPlay and Android Auto, Bluetooth, digital radio and an eight-speaker audio system.

There’s more details on the safety front below, and many rivals come with more modern in-car tech but there’s no question the Koleos offers very good value-for-money. 

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

The Koleos shares its powertrain with the X-Trail. That means it uses a Euro 5-rated 2.5-litre four-cylinder, naturally aspirated petrol engine delivering 126kW of power at 6000rpm and 226Nm of torque at 4400rpm.  

It is paired with a CVT and drives with the front, or all four wheels, depending on the grade. 

The Koleos has a braked towing capacity of 2000kg.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

According to Renault, the combined fuel consumption figure for the FWD Koleos is 8.1 litres per 100 kilometres. The AWD Koleos sips 8.3L.

After a week of mixed urban, freeway and semi-rural driving, we recorded 11.3L/100km.

Koleos uses 91 RON petrol, has a 60-litre fuel tank and emits 188g/km of CO2 emissions.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

The drive experience is a mixed bag with some highlights and lowlights.

The ageing 2.5-litre engine is responsive enough from a standing start - it has a 0-100km/h time of 9.5 seconds - but it lacks any real punch and becomes breathless the second you encounter a hill.

It is noisy and revs hard when pushed, with the CVT drone not making for a particularly pleasant aural experience. You’ll hear a fair bit of road and tyre noise in the cabin, too.

The steering is dull and feels quite artificial, but the brakes feel strong.

Unless you’re on a perfectly smooth road surface, the ride is a little busy and the damper tune fails to adequately soften corrugations, potholes and speed bumps. 

It is, however, a more capable handler than expected. The chassis is well sorted, and aside from feeling top heavy with body roll when cornering, it has decent grip and displayed impressive roadholding characteristics, even on a sweeping bend with a loose shoulder surface.

There was a little understeer detected turning into a particularly tight bend.

It can’t match the dynamism of the Kia Sportage or Mazda CX-5, but it does engage the driver to some extent.

The Koleos was awarded a five-star ANCAP crash safety rating back in 2017.

It comes as standard with six airbags, auto emergency braking, forward collision warning, lane departure warning, blind spot monitoring, cruise control, a reversing camera, front and rear parking sensors, and a tyre pressure monitor. 

It lacks some of the more modern active driver aids that are offered as standard in rivals, like an active lane-keeping system that helps ensure the vehicle doesn’t cross line markings. The Koleos makes do with an audible warning that, oddly, sounds like a whoopie cushion when activated.

The cruise control is not adaptive, instead it’s the old school version that doesn’t detect vehicles ahead and lower its speed accordingly. 

Having more up-to-date safety gear would improve the Koleos’ appeal.

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

The Koleos is covered by Renault’s five-year/unlimited kilometre warranty, which is stadatd in the meainstream market, now. 

It is available with a five-year capped-price servicing plan, with each service costing $429, except year four which will set you back $999.

The servicing schedule is every 12 months or 30,000km, whichever occurs first.
