Mercedes-Benz GLC-Class vs Jeep Wrangler

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 changes to this updated Jeep Wrangler are small but meaningful. The inclusion of airbags, the updated media screen, and a feisty engine which suits the plucky nature of this off-roader make it a better Wrangler than ever.

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.

The Jeep Wrangler looks like a cartoon of a four-wheel drive, that’s how familiar and well-known the design is. It’s almost generic, like the word Jeep.

You could say the design is iconic, given that the roots of this SUV stretch back to the little Willys off-roader built for the US army in World War II. And to this day the slotted grille, pronounced wheel guards, short and upright windscreen, even the removable doors are still with us in this latest incarnation.

That’s why each generation of the Wrangler only sees very subtle tweaks to famous shape and look, in much the same way a Porsche 911’s design changes at the rate of dripping water reshaping a rock.

Changing the styling completely would destroy the look which connects the Wrangler to its past and the nostalgic appeal would be over. 

So, this update sees more than subtle styling changes in the form of a tweak to the grille with the addition of a metallic-look trim around each of the slots while the mesh insert now has larger openings.   

Along with this there’s a new front bumper. The Wranglers we tested had the optional heavy duty steel front bumpers.

There’s also some interior changes in the form of a new dashboard trim, horizontal air vents and then there’s the 12.3-inch media display which goes a long way to making the cabin look more modern.

Still, the interior is busy with buttons and switches in a design that seems to mix the look of heavy machinery controls with a prestige car. The Nappa leather of the Rubicon grade lifts the quality feel higher.

All Wrangler interiors also have an internal roll-over cage which covers the entire cabin, for the fixed metal roof and removable roof body style which are standard on the Overland and Rubicon.

Only the Rubicon is offered in a two-door and a four-door, while the Overland and Sport S are four-door only.

The Rubicon two-door looks cute and fun to my eyes, while the four-door versions look a bit more serious and beefy, but both definitely still give off tough and adventurous vibes.

The wheelbase difference between the two is as giant as it looks. The Rubicon two-door’s wheelbase is 2459mm while the four-door Rubicon’s, along with the Sport S and Overland, is 3008mm.

The Wrangler ranges in length from 4334mm for the Rubicon two-door to 4882mm for the four-door Wranglers. Width is the same for all Wranglers at 1894mm and the height ranges from 1879mm in the Rubicon two-door to 1901mm in the four-door versions.

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.

When we review most SUVs practicality is scored on things like legroom, storage space and boot size. But in the case of a vehicle with removable doors and roof, and a cabin that has one-way drainage valves so you can hose the interior out, practicality takes on a different meaning.

The Wrangler’s practicality seems focussed on serving adventurous folks in search of a muddy off-road expedition and, so, while there is storage it’s mainly nets for door pockets, moulded wells on top of the dash, and smaller hidey holes to makes sure loose items don’t get flung around the cabin.

Given the roof can be removed there’s also a lockable glove box and centre console storage box.

When it comes to cabin space the Wrangler’s interior feels a bit cramped. The footwells up front don’t offer much space and headroom throughout is restricted by the roll cage which stretches from the front to the boot.

The four-door Wrangler has five seats and good legroom in the second row, even for me at 189cm tall. As mentioned above, headroom is limited in places because of the safety structure. Boot space behind those rear seats is 898 litres.

The two-door Rubicon has four seats. The back ones aren’t the most spacious and the boot behind them is almost too small to mention at 365L, Two pieces of carry-on luggage wouldn’t fit back there and we had to put our bags on the rear seats.

The rear tailgate for all Wranglers is side-hinged (opening left to right) and splits to allow just the window section or lower part to open separately.

For charging and powering devices all Wranglers have two USB ports up front (one -A and one -C) and four USB ports in the second row (two -A and two -C). There are also two 12V outlets on board (front and rear).  

There are two cupholders, seatback map nets and directional air vents for the second row.

The Wrangler sits high and climbing into the rear seats might be a challenge for smaller kids or even fully-grown humans, but there are chunky handholds at the pillars for extra help.

So, the Wrangler has excellent practicality, but this is geared more to its intended purpose of adventuring off-road rather than the city commute and school pick-up.

The Jeep Wrangler range comes in three grades. There’s the entry-grade Sport S which can only be had with four doors, the Overland which is also a four-door and the top-of-the-range Rubicon comes as a shorter wheelbase two-door and the four-door. 

The Sport S replaces the Night Eagle as the entry-point into the Wrangler range and with a list price of $75,950 it’s $5500 cheaper, too. 

Above this is the Overland for $84,950 and at the top of the line-up is the hardcore Rubicon which is $83,950 for the two-door and $90,450 for the four-door.

This update sees all Wranglers now coming with a (damage and scratch-resistant) 'Gorilla Glass' windscreen and a 12.3-inch media screen. But each grade also comes with its own new features. 

The Sport S has been given heated front seats, a heated steering wheel and ambient cabin lighting. Meanwhile, the Overland now has power front premium 'McKinley' seats and soft spare tyre cover.

And finally the range-topping Rubicon receives Nappa leather seats and a forward-facing 'Trailcam'.

There are mechanical upgrades across the range, too, especially for the Rubicon and we’ll get to those in the engine and driving sections of this review.

As for the rest of the features, coming standard on the Sport S are LED headlights, 17-inch alloy wheels, proximity key and push button start, sat nav, Apple CarPlay and Android Auto, a nine-speaker Alpine sound system and dark tint windows.

Along with its new features the Overland also comes standard with all of the Sport S’s equipment plus a three-piece removable hardtop, 18-inch wheels and a leather-wrapped shifting knob and hand brake handle.

Then there’s the Rubicon which has all the Sport S features, but 17-inch wheels instead of the 18s and an enormous amount of engineering hardware that makes this grade the off-road king of the Wranglers, which we’ll get to.

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.

One of the biggest changes Jeep could make to the Wrangler without causing complete mayhem for fans is to the engine and even then there will be folks who don’t like what they’re about to read.

Deep breaths, okay? Right, so, in this update the V6 petrol engine has been replaced by a 2.0-litre turbo-petrol four-cylinder. 

At 200kW the new four-cylinder makes a smidge less power than the V6 but more torque at 400Nm. An eight-speed automatic transmission shifts gears and sends the drive to all four wheels.

If you’re a Wrangler fan you’ll most likely know about this engine swap, but you’re wondering how this four-cylinder feels.

The answer is, really good. Jeep has got it right. It’s a torquey, responsive engine that feels energetic and suits the Wrangler's personality well.

In the short time I’ve spent on and off the road I’m convinced this turbo-four will be a good companion wherever you decide to go.

And go pretty much anywhere you can, with all Wranglers being ridiculously capable off-road thanks to their ladder frame chassis, high- and low-range gears, outstanding ground clearance (233mm-257mm, depending on variant ), excellent approach angle (41.4 to 44 degrees, depending on variant) and a departure angle to match (37 degrees for the both Rubicons; 36.1 for the Sport S and Overland).  

The Rubicon comes standard with Jeep’s 'Rock-Trac' on-demand four-wheel drive system and this update adds a full float rear axle. Sport S and Overland grades have Jeep’s 'Selec-Trac Active' on-demand 4WD set-up.

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 new turbo-petrol, four-cylinder means better fuel economy than the V6 it replaces. We have yet to test Jeep’s claims that after a combination of open and urban roads the four cylinder uses 9.2L/100km in the sport S and Overland grades and 9.9L/100km in the Rubicon.

In comparison, Jeep says the previous V6 uses 10.1L/100km in the Rubicon and 9.9L/100km in the Overland. Our own testing saw consumption closer to 13L/100km.

We’ll have the new Wrangler in our garage soon and we’ll be able to put the fuel consumption claims to a real world test.

In terms of range, the two-door Rubicon has a 61-litre fuel tank and in theory a range of up to 680km. The Sport S and Overland have an 81-litre tank and can get up to 880km, while the four-door Rubicon’s 81-litre tank should manage 830km.

Of course if you’re off-roading you’ll use more fuel and the range will drop accordingly.

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.

Every one of the Jeep launches I’ve attended over the past 15 years has involved a pretty decent off-road component and it’s clear the company has a lot of faith in its product.

This Wrangler launch’s off-road test had been scaled back due to days of flooding rain beforehand, but the section that was passable was enough to remind us of what we already know and that is the Wrangler is formidable.

A Queensland bush off-road course full of steep, muddy hills, ruts, rocks, dirt and slippery descents was still all there for us to test the Wrangler Rubicon four-door.

Fun and comfortable are the first words that pop into my head when recalling how the Rubicon fares. This is a super-capable beastie that feels planted, secure and adept at all times.

We tested low- and high-range four-wheel drive, locked the rear differential and let the hill descent mode do its thing and get us down the sides of hills that felt so close to vertical all we could see through the windscreen was the ground.

What's also clear is the new turbo-petrol, four-cylinder feels well suited to the job, with plenty of torque along with a feisty and responsive nature that fits the Wrangler better than the old V6.

There was also plenty of time spent on the road in the four-door Rubicon and its smaller two-door sibling. And was here it was also super clear the Wrangler felt like we’d taken it out of its natural habitat.

At 110km/h on the motorway the two door Rubicon feels light and floaty in its suspension, with steering adjustments having to be made constantly, like actors pretending to drive cars in movies, as the Wrangler wanders around in its lane. The Wrangler wander is a known trait and isn’t specific to this updated car. 

And even though our launch drive took us on some great winding country roads which would have been perfect for a Mazda MX-5, the Wranglers found the fast tight turns difficult to handle.

I’m sure I heard a sigh of relief from our Rubicon as we pulled off the road and selected low-range four-wheel drive before bouncing up what looked to be a sheer cliff, with ease.  

Of course, our Adventure Expert Marcus 'Crafty' Craft will put the Wrangler though its paces once we have one in the CarsGuide garage.

The Jeep Wrangler has a three-out-of-five star ANCAP rating from testing in 2019. This isn’t an adequate safety score for a modern vehicle and the relatively modest advanced safety tech compared to other new SUVs and its structural integrity in crash tests caused ANCAP enough concern to award it lower scores.

Surprisingly the ANCAP report scored its child occupant protection at 80 per cent which is excellent.

This update to the Wrangler now adds curtain airbags which cover the front and second rows. Along with these there are dual front airbags plus safety tech which includes AEB (city and inter-urban) and blind spot warning. There’s also adaptive cruise control and front and rear parking sensors.

For child seats you’ll find two ISOFIX and three top tether mounts across the second row of the four-door variants.

The standard full-sized spare wheel is mounted on the tailgate. 

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 Wrangler is covered by Jeep's five-year/100,000km warranty, which is off the mainstream market standard of five years/unlimited km.

Service intervals are recommended every 12 months and 12,000km and service prices are capped at $399. Jeep also offers lifetime roadside assistance if you service your Wrangler though Jeep.
