Mercedes-Benz GLC300 vs Genesis GV70

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 updated Genesis GV70 Electrified Signature Performance is packed with features, effortless on the road, and backed by fantastic ownership value. This isn’t just polished luxury, it’s smart luxury, making it a vehicle worth serious consideration. The only caveat? I’d opt for a different interior colour to white if you have kids or pets.

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.

Although slightly smaller than some rivals at 4715mm long and 1630mm tall, the GV70 comfortably fills out its medium SUV stature with a pronounced nose, wide stance, and pillowed, swoopy rear end. The update adds an exclusive reverse G-Matrix pattern in the grille, new 20-inch alloys, and a rear aerodynamic spoiler for a more distinctive presence.

Inside, there are three interior colours to choose from. Our test model’s white leather looks stunning but isn’t the most practical choice for families, pets, or anyone frequently navigating unpaved roads. A rainy day could make you anxious! The quilted leather upholstery shines visually, complemented by the new ‘Milky Way’ ambient lighting panels in the doors.

The electrified platform gives the cabin a flat floor, which improves legroom for middle-seat passengers, though it does mean there’s no space for a spare tyre in the boot.

Other notable updates include intelligent Matrix LED headlights, smart key sensors on all door handles, and new paint options. I particularly like the hidden charging port cover integrated into the grille; a subtle, clever touch. Overall, the GV70 is a handsome SUV.

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.

The GV70 Electrified Signature Performance feels spacious and comfortable front to back. Up front, the seats are thickly padded and packed with features, making it easy to find a good driving position. The electrically adjustable steering wheel adds to the ease, and the 172mm ground clearance with wide door openings makes getting in and out effortless.

Storage up front is a bit limited. The middle console and glove box handle most of the load, while door drink holders are slim. I do like the dedicated phone tray and sunglasses holder, which add some practicality to everyday use.

The 27-inch multimedia and instrument cluster display is sharp, high-tech and intuitive, while the responsive touchscreen and wireless Apple CarPlay/Android Auto make connectivity easy. The system includes built-in sat-nav, and you can customise it to fill the full screen while keeping a small speedo widget visible.

Charging is well-covered with two USB-C ports per row, a wireless charging pad, a 12-volt socket and a 250-volt domestic plug in the boot. Small practical touches like extendable sunvisors, manual rear sunblinds, smart key sensors on each door and the ability to move the front passenger seat or operate the boot from the driver’s seat add extra convenience.

In the rear, legroom is good and while I’m comfortable behind my driving position at 168cm, taller passengers may need to shuffle seats to optimise comfort. Seat cushioning is excellent, and the outboard seat heaters are a welcome touch. The bench is wide enough for three adults for short trips, and families will appreciate the two ISOFIX child seat mounts and three top-tether anchor points. Amenities include climate control, rear air vents, sunblinds and charging ports, although storage is limited to a couple of cupholders and map pockets. The pull-down armrest sits a little low for me, but my kid has no concerns.

Boot space measures 503L with all seats in place, the smallest compared with nearest rivals. That said, it easily accommodates my family of three’s groceries and school gear. There’s a small underfloor pocket for the tyre repair kit and home cables, plus a 22L frunk for extra storage. The powered boot lid is a practical convenience I always appreciate.

The updated Genesis GV70 Electrified Signature Performance comes in a single, well-equipped grade, priced from $132,800 before on-road costs. That puts it between two of its closest electric rivals - the Audi Q6 quattro e-tron at $122,500 and the Porsche Macan 4 from $134,400. Our test car also includes features that would typically cost extra on other brands, adding extra value.

The update brings significant tech upgrades, including wireless phone mirroring, a 27-inch OLED multimedia display, a new operating system with over-the-air software and firmware updates, a colour head-up display, 16-speaker Bang & Olufsen audio and a UV-C sanitiser for the middle console (the last one a little gimmicky for me).

The other technology is well-rounded with the addition of key sensors on all doors as well as keyless start, remote parking aid (via keyfob), three customisable driver profiles accessed via fingerprint, satellite navigation, a digital rear-view mirror and tri-zone climate control.

Inside, the Signature Performance feels distinctly premium. It features quilted Nappa leather upholstery, leather trims, a suede headliner, a panoramic sunroof and a powered tailgate. The front seats are electric, heated, ventilated and have massage and memory functions, while the rear outboard seats and electric steering wheel are also heated.

Put simply, there’s a lot included as standard.

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 GV70 Electrified Signature Performance is a fully electric SUV with dual motors, one on each axle, producing a combined 320kW of power and 605Nm of torque. Activate Boost Mode, and those numbers climb to 360kW and 700Nm, giving the GV70 a serious edge when you need it.

Despite its name, this grade isn't pitched as a performance EV but it's definitely no slouch with a 0 -100km/h sprint time of just 4.4 seconds with Boost Mode, or 5.0 seconds in standard mode. That’s quick enough to hold its own against rivals in the luxury electric mid-size SUV segment, while still delivering smooth, linear acceleration that’s effortless in everyday driving.

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 GV70 Signature Performance runs on a new 84kWh lithium-ion battery, giving a WLTP driving range of up to 462km which is a solid figure for both city commuters and regional drivers, provided you charge regularly. Genesis includes a couple of charging cables, and the SUV also offers V2L (Vehicle-to-Load) capability, ideal for powering larger devices while stopped.

Charging options are strong. The Type 2 CCS port accepts up to 11kW on AC chargers and up to 350kW on DC fast chargers, allowing a 10 - 80 per cent charge in as little as 19 minutes on a 350kW unit or seven hours and 35 minutes on an 11kW AC charger. Realistically, most DC chargers on the road operate closer to 170kW or below, which still delivers a very usable recharge.

The GV70 also features four levels of regenerative braking, including a one-pedal mode. Staying mostly in this mode over the week, I achieved an energy consumption of 21.0kWh/100km, which is very close to the claimed 20.0kWh/100km and again, is a solid result for a car of this size and outputs.

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. 

My kid called the GV70 the 'Marshmallow Limo' this week, and it’s an apt description for the ride comfort. The SUV probably delivers the one of the most comfortable rides I’ve experienced, thanks to soft suspension and new hydro bushings in the rear, which smooth out most vibrations. The trade-off is that it feels dampened when cornering and you glide over the road rather than feel it, which I find a little soft, but my husband loves.

The dual motors provide strong, prompt acceleration, and Boost Mode adds an extra kick when you need it. The cluster pulses red while active, which is a fun touch.

Visibility is excellent. The wide windows give a clear view around the car, and none of the pillars obstruct from my driving position. The digital rear-view mirror is particularly handy when carrying passengers or cargo.

Regenerative braking is easy to control via the steering wheel paddles. Mode 3 and the one-pedal function deliver strong regen without being harsh, but you need to adapt your braking technique, otherwise passengers might feel a little queasy.

Despite looking larger than it is, the GV70 is simple to park, thanks to an 11.5m turning circle and a 360-degree camera system, though the multiple view modes can feel overwhelming at first. I also love the remote parking via keyfob, which comes in handy in tight carparks or garages.

The GV70 Electrified Signature Performance carries a maximum five-star ANCAP safety rating from 2021 testing and comes with eight airbags as standard. One standout feature is the blind-spot view monitor, which displays a live video feed of your blind spot on the instrument cluster.

The update adds several new safety technologies, including parking collision avoidance assist for the front, side, and rear, as well as side parking sensors. Adaptive cruise control is now navigation-based, adjusting speed automatically for low-speed zones and curves in the road. Other standard safety equipment includes an active bonnet, lane keeping aid, lane departure warning, tyre pressure monitoring system, 360-degree camera, rear cross-traffic alert, forward collision warning, safe exit assist and driver attention warning.

Family-friendly features are also well catered for, with ISOFIX child seat mounts, three top-tether anchor points, rear occupant alert, intelligent seatbelt warnings, and rear child locks.

The autonomous emergency braking (AEB) with car, pedestrian, cyclist and backover detection is operational from 5.0 - 85km/h but it is usual to see the top figure sit well over 100km/h, especially for car detection.

Overall though, the GV70 combines a comprehensive suite of active and passive safety systems.

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 GV70 Electrified Signature Performance comes with a five-year/unlimited kilometre warranty and an eight-year/160,000km battery warranty, putting it in line with its rivals. What sets it apart are the extras included at no additional cost.

Genesis provides free scheduled servicing for five years or up to 75,000km, along with five years of roadside assistance through Assist Australia, and if you service through Genesis, that cover extends to ten years.

Owners also receive a complimentary five-year subscription to Genesis Connected Services and can choose either a five-year Chargefox subscription or an at-home wall-box charger.

Another practical bonus for regional drivers is that you aren’t limited to Genesis dealerships for servicing. You can use any of the hundreds of Hyundai service centres for scheduled maintenance, which makes ownership far more convenient. Overall, Genesis makes it easy and appealing to own a GV70.
