Mercedes-Benz GLC300 vs Kia EV5

What's the difference?

The GLC300 Coupe isn't quite as great when it comes to being a family car as the regular SUV version of the GLC, and that's purely down to the sloping roofline which not only makes access more difficult to the second row but reduces boot capacity.

That said, the GLC300 Coupe makes a much better family car than a Mercedes-Benz C-Class sedan, or any sedan.

Easy and enjoyable to drive, packed with great features and still practical, the GLC300 Coupe would still cut it as a good family car.

The size is right, the price is right and the drive is right – three things that make the Kia EV5 a pretty formidable foe, and the kind of vehicle that might finally be able to break through the wall of the temple of Tesla in Australia.

Coupe SUVs aren’t for everybody… they’re not even for lots of people. But the design of an SUV with its roof cut down so that it meets the tailgate at an almost sportscar-like angle appeals to more than a few fans. The thing is they don’t just like the look, they love it, and they also probably enjoy how much the styling makes other people cranky.

To my eyes the GLC300 Coupe is the best execution of the bodystyle compared to those of BMW and Audi. There’s an elegance to the GLC300 Coupe and the AMG-line adds a tough look that only enhances the solid, powerful but pretty look.

The GLC Coupe is a mid-sized SUV and this new generation model is a bit bigger the previous one and now measures 31mm longer at 4763mm end to end, it’s 1890mm wide, 1605mm tall and has a wheelbase of 2888mm.

It’s also more aerodynamic than ever. No seriously, it’s drag coefficient is now 0.27 and it looks like a bar of soap - and it's about as slippery as one, too.

More curved surfaces await inside with a dashboard that pours down into the large centre console and it's adorned with a sloping and large portrait-style media screen. 

At night or in tunnels the ambient lighting glows through the air vents and skirts the edges of the door trims, console and dashboard.

It’s a minimalist and high-tech cockpit with modern sports seats up front and a Nappa leather wrapped steering wheel with its twin blade design.  

So, how does the coupe design work for family practicality? Let’s take a look.

If you’re familiar with any of Kia’s EV designs, and specifically the EV9, you’ll already know the Kia EV5, which looks a lot like a shrunken version of the company’s biggest electric 4WD.

But this one looks a bit smaller, a bit more familiar looking, and maybe a bit more accessible than the hyper-modern EV9.

Honestly, it looks like a contemporary, mid-size SUV that could be powered by anything.

There are a couple of EV5 design elements I really like. The first is the combination of hard edges and subtle curves, which combine really well. I also love the lighting treatment up front, which gives the EV5 a bold and unique light signature, especially at night.

Inside, it’s another story of familiarity, with a clean, high-tech cabin and Kia’s common twin-screen set-up. Actually, it’s more a triple screen, with two 12.3-inch screens, and a 5.0-inch climate monitor between them.

The materials are all nice, and they look great, but they don’t exactly melt under the touch, and that gives the EV5’s cabin a hard edge I don’t love.

I do, however, love the inclusion of some physical buttons, so you’re not pawing through the screen to access every in-car function.

And one final design quirk. I know it looks like it has an old-school bench front seat, but you can’t use it as a third seat in front. Kia says it’s just a design flourish. But it is also somewhere safe to pop your phone or other small valuables to stop them sliding about when you're on the road.

SUVs are the most practical cars for families because of the better access to the cabin thanks to their large doors and slightly elevated ride height, their big boots with wide and tall hatch openings and their high flat rooflines. They’re essentially raised station wagons.

A coupe-style SUV still has four doors but they are less boxy due to the sloping roofline which falls away quickly to meet the tailgate at a lower point. The effect is a sporty-looking shape but practicality is lost in this exercise of form over function.

The second row doorways aren’t as large as those on the regular SUV. I did a side-by-side test and felt like I had to duck under the sloping roof when getting out of the back seat.

The smaller opening also made it trickier to lift my toddler daughter into her baby seat.

The sidesteps are also surprisingly handy for bigger kids and my eight-year-old used them every time when climbing into the car.

Cabin storage is outstanding with huge door pockets and cupholders in both rows, and while the 545-litre boot in the GLC300 Coupe is 80 litres smaller than the cargo capacity of the regular GLC SUV, it's bigger than the previous version of the Coupe.

As for people space, there’s enough headroom for me at 189cm tall in the back seat and heaps of legroom, even behind my driving position.

I’ve mentioned the lack of climate control in the second row, but also should point out that there are no USB ports back there either.

There are USB ports in the big centre console box upfront and a long cord should be able to make it to the second row. 

There’s a wireless phone charger but it's housed in the bowels of the centre console too, and you’ll need to weave your hand while clasping the phone under the shiny black trapdoor, past the cupholders possibly with drinks in them and almost under the dashboard.

At 4615mm in length, 1875mm in width, 1715mm in height, and with a wheelbase of 2750mm, the Kia EV5 is roughly the same size as a Tesla Model Y, so if you’re ever sat in the back of the Tesla, you’ll have a fair idea of what to expect here.

Sitting behind my own 175cm driving position, I found I had a heap of knee room, more than enough headroom, and I reckon you could fit three adults across the back seat pretty easily, too.

There are a couple of design flourishes I really like, too. The pull-down divider that separates the backseat is home to two cupholders, which isn’t unusual, but what is new to me is the unique positioning of the USB charge ports, which are in the middle-back of the front seats, right above the storage pocket, so you have somewhere to pop your phone and cable when you're charging.

There is also a deep storage draw between the two front seats. It’s just for extra storage in the Air and Earth, but in the GT-Line it’s heated and cooled, which means hot pies or cold drinks when you’re on the move.

The EV5 might be an all-electric vehicle, but it’s still a mid-size SUV, which means there are certain standards it has to hit to be taken seriously, and one of those is boot space.

Up front there’s 67 litres of space in the fruit, or frunk, while the boot holds 513L with the rear seats in place – that number obviously growing as you begin folding them flat.

It is also a hugely customisable space. There’s heaps of under-floor storage below the removable panels. There’s also vehicle-to-load capability, which takes the form of a standard power point in the boot that can use the vehicle’s battery to power pretty much whatever you want.

Finally, there are adjustable luggage hooks, so you can carry bigger or smaller bags as you wish.

The cheapest EV5, the Air, arrives in two guises, Standard Range or Long Range, and the former is something of a bargain.

It’s the only EV5 to get included on-road costs, and Kia is asking $56,770, on the road. That puts it well below the Tesla Model Y. As of right now, the single-motor Tesla is $60,868, on the road, in NSW.

Next is the Air Long Range, which lists at $61,170, before on-road costs. The EV5 Earth occupies the middle rung, at $64,770, before on-roads, while the yet-to-arrive flagship, the GT-Line, is a considerable $71,770, before on-road costs.

Air models get 18-inch alloys, LED lighting all around, roof racks and power mirrors, while inside there are cloth and synthetic leather seats, with a massage function for the driver, along with a synthetic leather steering wheel and LED interior lighting.

Tech is covered by twin 12.3-inch screens, with a smaller 5.0-inch climate screen sandwiched between them, and there’s in-built nav, a six-speaker stereo and Apple CarPlay and Android Auto.

The Earth then adds 19-inch alloys, gloss black exterior design flourishes and privacy glass, while inside, the seats are now entirely synthetic leather. You also get a second V2L connection, as well as a powered tailgate.

Finally, the GT-Line gets pretty much everything Kia could throw at it, including 20-inch alloys, auto-flush door handles, a panoramic sunroof, two-tone seats which are now billed as offering "premium relaxation", wireless phone charging, fingerprint recognition, a heated steering wheel and an augmented-reality head-up display.

The GLC300 Coupe has a 2.0-litre four-cylinder turbo-petrol engine making 190kW of power and 400Nm of torque.

There’s also an overboost function which allows the engine to make an extra 17kW and 200Nm just for a brief moment, but that extra dollop of grunt combined with the regular output provides impressive acceleration (0-100km/h in about 6.3 seconds) for overtaking or moving quickly when you need to.

A smooth nine-speed automatic transmission sends the drive to all-four wheels.

The GLC300 Coupe is all-wheel drive and while there’s a setting for rougher terrain, along with one for comfort, eco and sport, but I’d make sure that it doesn’t get any more adventurous than tame gravel and dirt roads.

Mercedes-Benz refers to the GLC300 Coupe as a mild hybrid and this is because it has a 48-volt system and an integrated starter-generator.

This type of hybrid doesn’t use electric motors, doesn’t drive the wheels and won’t save much fuel, but it will provide efficiencies by supporting the engine and when coasting, plus will reduce petrol consumption to a small degree.

The entry-level EV5 Air is available in Standard Range or Long Range guises, both powered by a single front-mounted electric motor, producing 160kW and 310Nm. 

The Standard Range will clip 0-100km/h in 8.5 seconds, while the extra weight of the bigger battery slows down the sprint in the Long Range, taking around 8.9 seconds. 

The Earth is a twin-motor AWD offering, with a motor at each axle, lifting outputs to 230kW and 480Nm, dropping the sprint to a brisk-feeling 6.1 seconds. The incoming GT-Line gets the same powertrain.

As we mentioned above the GLC300 Coupe's 48-volt mild hybrid system is not the kind of hybrid that will allow you to drive miles on electric power, nor will it dramatically reduce fuel consumption in the way a parallel, series or plug-in hybrid will. But every bit of efficiency helps.

Mercedes-Benz says the GLC300 Coupe will use 7.7L/100km after a combination of open and urban roads. 

We had the GLC300 Coupe for just two days, but in that time my family covered 176km of regular daily usage which took in motorways but mainly suburban duties such as the school run, supermarket dashes, that sort of thing.

In our fuel test we measured 14.48 litres at the fuel pump which works out to be an on-test fuel use figure of 8.2L/100km and not far off the manufacturer’s claim. 

While this fuel consumption isn’t overly high, a plug-in hybrid or even a parallel or series hybrid could return about 5.0L/100km or less.

Mercedes-Benz has dropped plug-in hybrids from its Australian range which is a shame because it would be good to see more efficient options in the GLC range. Of course if you want more efficiency from a Benz of the same size, there is always the fully electric EQB or EQC.

The Air Standard Range gets a 64.2 kWh lithium iron phosphate battery, weighing in at a hefty 428kg, which delivers a claimed driving range of 400km. The Air Long Range, the Earth and the incoming GT-Line all share the same 88.1kWh battery, upping the range to 555km, 500km and 470km, respectively.

So, if driving range is at the very top of your must-have list, the Air Long Range is the car for you.

All cars can take 7.0kW home AC charging, while the dual-motor versions are set up for 11kW AC charging. Fast charging. When it comes to fast charging, all models can plug into a 350kW charger, taking them from 10 percent to 80 per cent in less than 40minutes.

There’s a lot to like here but the short version is the GLC300 Coupe has a comfortable ride, but good handling, with a responsive engine, although rear visibility through the small back window is poor.

If we drill down a bit further I can tell you that excellent cameras around the car will help you check to make sure kids aren’t running around behind you and that forward and side visibility through the window is good.

An important takeaway is that the GLC300 Coupe is easy to drive with light steering and an engine that’s mild and controlled in its power delivery.

The gear shifter is mounted on the steering column, in the same way an indicator lever is. So putting the car into Drive, Reverse and Park is so easy and means you don’t have to take your hands off the steering wheel. 

As a family car I liked the good body control and composed ride. We have a small toddler that we can sometimes only get to sleep by taking her for a drive and we found that she could nod off and not be woken by potholes and speed bumps or too much leaning in the corners. 

First things first – I spend most of my time behind the wheel of the EV5 Earth, which though it shares its dual-motor powertrain with the GT-Line, is actually the fastest of the lot owing to the extra weight of Kia's flagship.

That means zero to 100km/h in just over six seconds, and trust me when I say this, that is more than fast enough. I know you read about EVs knocking off the sprint to 100km/h in supercar-besting times, but you don't need that sort of crazy acceleration in a family-focused mid-size SUV.

Actually, forget needing, you don't want it. The EV5 feels more than punchy enough, without shaving years off your life every time you plant your foot.

Fit for purpose, then, which is exactly how I'd describe the rest of the EV5's very good drive experience. Kia's Australian ride and handling wizards have once again had their way with the EV5, and the result is an EV that handles most everything Australian road surfaces can throw it at it with ease.

Surprisingly, it's maybe not quite as dynamically sharp as the bigger EV9, but it's always comfortable, without feeling floaty or disconnected, and it will happily grip its way around tighter corners without tipping from side to side, either.

There are a couple of small quirks, though. The first is the steering, which is definitely responsive and confidence inspiring, but it also has a kind of artificial weight or heaviness at times that feels a bit disconnected from what's happening beneath the tyres. And the cabin can be a little noisy through wind, too.

But these are small beans, really. The EV5 is comfortable and capable, and without the harsh ride or too-sharp steering that can be found in some of its rivals.

We drove it for hours across all sorts of road surfaces, and in all sorts of conditions, and found very, very little to complain about.

Every EV5 gets a comprehensive safety offering, including 'Advanced AEB' that includes junction crossing, lane oncoming and lane changing alerts. There’s rear-cross-traffic alert, semi-autonomous highway cruising and a whole heap more.

If you want a blind-spot view monitor, surround-view monitor or remote park assist, you’ll need to spring for the GT-Line.

The EV5 hasn’t been crash-tested yet, but Kia will be shooting for the maximum five-star ANCAP rating.

The GLC300 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty. 

Services are annually or every 25,000km. And you can buy a three-year service plan for about $3000.

The EV5 is covered by Kia’s seven-year, unlimited-kilometre warranty, and you can prepay your servicing costs, too.

Three years will set you back $980, five years is $1535 and the full seven years will set you back $2431 ($347 per workshop visit), which is category competitive.
