Land Rover Defender vs Mercedes-Benz G63

What's the difference?

The Land Rover Defender 130 P500 V8 is big, roomy and great to drive. It’s supremely plush without sacrificing practicality and if you’re in the market for a spacious, comfortable and refined package and aren’t afraid to open your wallet, then this long Landie is well worth your consideration.

Do you need the V8? Of course you don’t – and the diesel variants make a lot more sense anyway in terms of day-to-day fuel efficiency – but, geez, it's a lot of fun to drive.

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 Defender 130 measures 1970mm high, 5358mm long (including rear-mounted spare wheel; 5099mm without), and 2105mm wide (with the wing mirrors out). It has a 3022mm wheelbase and a listed kerb weight of 2745kg (unladen).

It is big, but really it’s no more intimidating to drive than a Toyota LandCruiser 300 Series or Nissan Patrol.

Upper large SUVs have a Federal Chamber of Automotive Industries-defined footprint bigger than 9801mm – think 300 Series LandCruiser (close to 5.0m long), Hyundai Palisade (almost 5.0m long) and Nissan Patrol (almost 5.2m long).

In terms of styling, the 130 strikes an effective balance between the distinctive shape and spirit of the old-school Defender with the new-generation’s pomp and presence – and the striking Carpathian Grey paint on this variant complements that blend.

The current-generation Defender is no city-soft shadow of its former adventure-tackling self that Landie lovers everywhere feared it might be. But it’s modern and sleek enough to put the minds of urban dwellers/weekend warriors at ease.

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.

The Defender 130 is well-suited to people-carrying duties thanks to its three-row seating.

And don’t forget this test vehicle has (optional) Captain Chairs in the second row. 

The cabin has a distinctive premium look and feel about it, without sacrificing anything in terms of just how practical it all is. It’s a pleasant mix of durable materials – carpet mats and soft-touch surfaces – and stylish touches, such as a metal Defender-stamped section in front of the front passenger. 

Layout is user-friendly and this is an easy cabin in which to swiftly become comfortable as all controls easy to locate and operate even when busy negotiating with your teenagers who gets what song next.

Storage spaces include a deep centre console, glove box, twin cupholders between driver and passenger, sunglass storage, door pockets and shallow spaces positioned about the cabin for your everyday carry gear.

Charge points include USB-Cs up front and a wireless device charging tray.

The driver and front passenger get ample room and plenty of amenities and those behind them also fare well with adequate room for everyone – even those in the third row. 

All seats are comfortable and the front seats are 14-way power-adjustable with heating, cooling and memory.

The second row – two outboard Captain Chairs in this test vehicle – have a headrest and armrests for both passengers.

The third-row seats are heated and configured in a 40/20/40 pattern.

The rear cargo area is small in this seven-seater, although it offers a listed 389 litres with all three rows up and in use. That area has a sliding cover (which conceals your valuables from the prying eyes of nefarious types), cargo-restraint points, power sockets and a shallow underfloor storage space.

With the third row folded down, there is a listed 1232 litres of space. The maximum loadspace volume behind the front row is a listed 2231 litres.

There is a lot more to admire inside this Defender’s cabin for those who love the interiors of plush SUVs, but rather than spending my time stroking leather accents, going ‘ohhhh-ahhhh’ over a sunroof or reflecting on the butt-warming benefits of a heated seat, I like to actually drive. 

So I did. A lot.

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.

The Land Rover Defender 130 P500 V8 has a 5.0-litre supercharged V8 petrol engine (producing 368kW at 6000-6500rpm and 610Nm at 2500-5000rpm), an eight-speed automatic transmission and all-wheel drive system.

This is a very effective and fun combination of gutsy V8 and clever auto.

The Defender has permanent all-wheel drive and a dual-range transfer case with high- and low-range 4WD.

It also has Terrain Response 2, an off-road-focussed driver-assist system, which will make any off-roading newbie look and, more importantly, feel like a dirt-track driving champion.

The system includes switchable modes - 'Grass/Gravel/Snow', 'Sand', 'Mud and Ruts' and 'Rock Crawl'. 

This tech optimises throttle response, engine outputs, transmission shifts and diff control to best suit the terrain. It also has centre and rear diff locks.

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.

Fuel consumption is listed as 12.7L/100km and that's on a combined (urban/extra-urban) cycle. On this test I recorded 14.9L/100km.

The Land Rover Defender 130 P500 V8 has an 90-litre fuel tank so, going by my on-test fuel figure, you could reasonably expect a driving range of about 604km from a full tank. 

Fuel requirement is 95 RON premium unleaded. 

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.

What's it like to drive? It’s bloody great.

This is a big vehicle – have I mentioned that already? – but powered by this V8 the Defender 130 punches along with nary a care in the world. 

Throttle response is crisp, and the 5.0-litre supercharged petrol’s 368kW and 610Nm are always readily available for a snap-punch standing-start, or to smoothly and safely overtake other vehicles on the open road.

This Defender has an official 0-100km/h sprint time of 5.7 seconds and a listed maximum speed of 240km/h!

By the way, it doesn’t hurt that the V8’s growl is piped through quad outboard mounted exhausts.

The eight-speed automatic transmission is supremely clever but the shifter’s stubby size and awkward location (under the multimedia system’s touchscreen) is annoying.

Otherwise, this V8 130 is smooth and refined, with tremendous road-holding abilities despite a Landie legacy of past-generation Defenders being about as composed as dodgy tractors.

What’s more, comfort levels are exceptional in a vehicle model once considered a form of punishment in which to travel.

Steering has a well-weighted driver-friendly feel to it and this upper large SUV never feels too cumbersome to navigate through even busy city streets, even though it has a turning circle of 12.8m.

Some body roll creeps in every now and again – especially when you become energetic throwing this giant around corners, etc – but otherwise this big bulky vehicle is well controlled and comfortable.

The air suspension negates the majority of thumps and bumps you might be expecting to get from a vehicle riding on 22-inch wheels and low-profile tyres over irregular road surfaces.

Our test vehicle was on 22-inch rims and 275/45 R22 Continental CrossContact RX “SUV performance” tyres, which are fine for driving on sealed surfaces, but if you’re looking to do any off-roading in this Defender get a set of more appropriate all-terrains.

I wasn’t driving the 130 to test its 4WDing prowess this time, but it’s still worth noting the Defender’s off-road measurements include 293mm of ground clearance (with air suspension), a wading depth of 900mm, and approach, departure and ramp-over angles of 37.5, 25.8 and 27.9 degrees, respectively.

This Defender 130 has a gross vehicle mass (GVM) of 3380kg and a gross combined mass (GCM) of 6380kg.

It has an unbraked towing capacity of 750kg, and braked towing capacity of 3000kg (with maximum 300kg on the towball), which is somewhat of a disappointment and sub-par for the upper large SUV segment.

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 Defender has a five year/unlimited km warranty with five years of roadside assistance included.

The vehicle will let you know when it needs to be serviced – isn’t it bloody clever? – and prepaid service plans are set for five years/130,000km (maximum km) at a total cost of $3750.

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.
