Mercedes-Benz GLC-Class vs Genesis GV70

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

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.

The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

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.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

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.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

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.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

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.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

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 GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

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.
