Jeep Wrangler vs Mercedes-Benz G-Class

What's the difference?

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.  

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

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.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

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 G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

Okay, you're laying down a quarter of a million bucks ($247,329 before on-road costs) and it's fair to expect some serious tech and standard equipment to keep you feeling warm and fuzzy after you're finished impressing friends and family with the G 63's howling acceleration.

For a start, there's a bunch of leading-edge safety tech on-board (detailed in the safety section below), and as expected that substantial cost-of-entry brings an extensive list of luxury features.

We've touched on the twin 12.3-inch 'Widescreen Cockpit', and available media includes digital radio and TV tuner, internet connectivity and 3D nav (with dynamic route guidance), as well as smartphone integration with Apple CarPlay and Android Auto.

Audio is a thumping 15-speaker, and 590-watt Burmester surround sound system, and the ambient lighting set-up offers a choice of 64 colours.

Also included are 'Multibeam' LED headlights, 'AMG Ride Control' adaptive damping, a 'Parking Package' with 'Active Parking Assist' and 360 camera, a sliding glass sunroof (with tilt function), the selectable AMG sports exhaust system, keyless entry and start, the AMG Performance steering wheel (trimmed in nappa leather), and 21-inch AMG '5-Twin spoke' alloy wheels.

Then there are the three 100 per cent differential locks (plus an 'off-road information centre'), electronically adjustable front seats (ventilated front and heated front and outer rear), steering column and mirrors (with memory function), three-zone climate control, nappa leather upholstery, a leather-finished dashboard with open-pore ash wood trim, a 'Dinamica' microfibre roof liner, and an AMG-specific IWC design analogue clock. Plus, the 'Dynamic Select' system enables a choice of pre-set driving profiles or individual settings.

The optional 'Exclusive Interior Plus Package' ($10,300) fitted to 'our' car adds deluxe nappa hide on the dashboard, door centre panels and grab handle, as well as a diamond quilted treatment on the seat centres, a black 'Dinamica' roof liner, velour floor mats (with edging in nappa leather), a frameless interior mirror and air vents in 'Silvershadow'.

On top of that the test vehicle was optioned with the 'Night Package' ($5900) detailed in the Design section, and Designo 'diamond white bright' paint ($5900) for a manufacturer's recommended list price (MRLP) of $269,429.

That puts the G 63 in the same price and equipment ballpark as the supercharged V8 Range Rover Autobiography ($268,900), twin-turbo V8 Porsche Cayenne Turbo ($239,400), and its Mercedes-AMG GLS 63 sibling ($221,729), powered by a version of the 5.5-litre twin-turbo V8 used in the first-gen G 63.

An impressive trio of alternatives, but in reality the idiosyncratic G 63 doesn't have any direct competitors, and for those who give in to the pull of its powerful tractor beams value-for-money becomes a uniquely personal concept.

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.

The G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

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.

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

The second-gen G 63 hasn't been assessed by ANCAP or Euro NCAP but its new electronic architecture brings the car up to speed on active safety tech, now incorporating 'Distronic' cruise control with 'Active Distance Assist', 'Active Brake Assist', AEB (forward and reverse), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Adaptive High-Beam Assist', tyre pressure monitoring, and 'Traffic Sign Assist'. Plus, the 'Pre-Safe' system prepares the vehicle and occupants in the face of an inevitable collision.

And once that impact has occurred, you're protected by nine airbags, including rear seat airbags, full-length curtains and a driver's knee bag.

There are three top tether points for child restraints/seats across the back seat, with ISOFIX anchors in the two outer positions.

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. 

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.
