Hyundai Elantra vs Mercedes-Benz GLC-Class

What's the difference?

The Elantra might be overlooked compared to its famous i30 stablemate, but it shouldn’t be. It’s every bit as entertaining to drive and just as well equipped.

It’s a shame active safety is on the option list for lower trim levels, and there’s no radar features on higher ones, and the unnecessary styling changes might polarise buyers. But the Elantra is otherwise a well-equipped and rewarding-to-drive package across the range.

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.

Despite being a facelift of the rather good looking 2016 Elantra, the 2019 car has taken a hard turn into the domain of triangles and right-angles.

The new styling has proved controversial in the CarsGuide office. The Go and Active seem to have largely abandoned many of the styling points which Hyundai has invested in over the past few years, with their vertically lined grilles and abundance of triangle light fittings.

All the extra space on the big, flat rear is taken up by the big-font ‘Elantra’ text and Hyundai logo, which is '90s-style in design.

The Sport and identical-from-the-outside Sport Premium are angry looking cars, with frowning LED light fittings, giant alloys and an abundance of angular black highlights.

The side skirts, rear diffuser and spindle grille give the Sport variants an impressive amount of presence on the road. There’s no spoiler to be found, though.

Inside, the Go and Active are a fairly basic offering, with the Active scoring a leather wheel and some extra niceties. The dash is a sea of grey, however, and the nice touchscreen is humbled by its old-school in-dash positioning.

The Sport grades add some more sophisticated touches, with sporty leather-trimmed seats, a flat-bottomed steering wheel and a more subtle climate-control console rather than the clunky air-conditioning one used in lesser variants.

All cars have a sensible trip computer and simple gauges in the instrument cluster.

Missing from any variant is a digital dashboard as seen in the Honda Civic. There’s also the argument that the Elantra’s cousin, the Kia Cerato, has a more forward-thinking cabin design.

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.

Up front, the Elantra offers decent room. The Cabin feels a smidge more spacious than its i30 hatch sibling, and there’s plenty of leg and headroom on offer in every variant - except for the sport premium, which has a cropped roofline due to the sunroof. While there’s a decent centre console box, the door lacks a bit of padded trim for your elbow.

Like the rest of Hyundai’s range, the Elantra has a slew of generous cubbys and cupholders throughout the cabin. Underneath the air-con console is a deep trench which houses a 12v output, USB port and, in the Sport Premium variant, the Qi wireless phone charging pad.

Rear passengers are granted great legroom and decently sized cupholders in the doors, as well as a drop-down arm rest with two more cupholders.

The Active and Go lack rear air vents, whereas the Sport and Sport Premium offer two for back-seat passengers.

The available boot space should serve as a reminder why sedans shouldn’t be overlooked for practicality reasons, with 458 litres VDA on offer. Still, it is bested in this segment by the luggage capacity of the Cerato (520L), Civic (517L), and Impreza (460L). A rubber cargo liner and fabric bumper protector are available as genuine accessories.

In an annoying niggle, the Sport variants ride quite low around their midsections due to the flared bodykit bits. I found these would quite easily scrape if you weren’t careful over speedbumps or shopping centre ramps. Go and Active variants were fine in terms of clearance.

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 power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.

The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain. 

That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.

To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.

Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.

There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering. 

Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills,  carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.

There are two engines in the Elantra range. A dated 2.0-litre non-turbo engine which has hung around for a long time in Hyundai’s stable, and a much newer 1.6-litre turbo engine in higher variants.

Unlike the i30, there’s no option for a 1.6-litre turbo-diesel. Any EV and plug-in hybrid versions are still beyond the horizon (perhaps pending the success of the Ioniq).

The Go and Active variants share the 2.0-litre engine which produces 112kW/192Nm. The Go is available as either a six-speed manual or a six-speed traditional torque converter automatic. The Active is six-speed auto only.

The Sport and Sport Premium are powered by the excellent 150kW/256Nm 1.6-litre turbo. Aside from the Kia Cerato GT, which shares the same engine, the next closest competitor at this price point is the outgoing Mazda3 SP25 (139kW/252Nm).

The Sport and Sport Premium can either be had with a six-speed manual gearbox or a seven-speed dual-clutch automatic, and can cycle between ‘normal’, ‘sport’ and ‘eco’ drive modes.

The Elantra range is a strictly front-wheel-drive affair, as there’s no option for all-wheel drive.

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.

All 2.0-litre Elantras have claimed/combined fuel usage figures of 7.4L/100km. Against this claim I scored a very reasonable 8.0L/100km in my road test of the Active.

The 1.6-litre variants have a marginally better claimed consumption figure of 7.0L/100km against which I scored 9.0L/100km in my test of the Sport. If you’re having fun, expect at least 9.0L or above. That’s a compliment.

All Elantra variants happily consume regular 91RON unleaded and have 50-litre tanks. Good stuff.

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.

All Elantra variants are great to drive. They share excellent suspension and steering characteristics, lending them a rewarding experience in the corners while not being too stiff or too soft over bumps.

The 2.0 litre variants offer, well, acceptable power, even if they're a little on the thrashy side, and their ride comfort is boosted by sensibly sized alloy wheels and soft rubber.

Sport variants are genuinely a blast to drive. The 1.6-litre turbo has small amounts of lag, but is otherwise strong through 1500-4500rpm. Torque steer is present but manageable, and even adds a little to the excitement.

Thick (and pricey) Michelin Pilot Sport 4 tyres (225/40R18s) help keep the Elantra Sport planted and surprisingly grippy through the corners.

Road noise is acceptable but not stellar across the range. The same goes for the 10.6-meter turning circle.

Truly gone are the days where you should question whether Korean cars can be fun; the Sport and Sport premium do a better job of channeling the characteristics of Japanese sports sedans of the '90s and '00s better than most current Japanese nameplates.

On the downside, the silly flared body kit on the Sport variants limit ground clearance on ramps or speedbumps and can be prone to bottoming out. This combines with the easily scratched giant wheels to make for some nervous driving.

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.

The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.

A parking system that includes a 360-degree camera and active parking assist is also included.

The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.

Hyundai covers its range with an on-par five-year, unlimited-kilometre warranty promise offered by most of the competition. It is outdone by its mechanical twin, the Kia Cerato,with its seven-year warranty.

Hyundai’s fixed service program is one of its strong suits, with service pricing on turbo Elantra models locked between reasonable $273 to $460 costs per visit, locked all the way out to 168 months/210,000 kilometres. And even beyond that there's the optional pre-paid ‘iCare’ packages. Costs are slightly less for 2.0-litre cars.

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.
