Land Rover Defender vs Mercedes-Benz SL-Class

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 SL's overall score is somewhat skewed by everyday concerns, and rules are rules - an average punter will find the price of this car somewhat confusing and the devil-may-care attitude to fuel consumption bewildering.

If neither of these things are a problem, then the SL63 makes plenty of - well, not sense, because it's not a particularly clever or considered car - but it fills a niche that not so long ago we all thought would go the way of the dodo.

The fact it sells so few examples is betrayed by some of the cabin amenities and the fact that Mercedes hasn't put much effort into reducing the car's weight to improve its consumption or sharpen up the handling.

The fact it still exists at all is pretty damn cool, though, and for certain people an SL63 purchase is the culmination of a lot of hard work.

If it is your dream car, the SL63 won't disappoint. Everyone who rode with me said it was mightily impressive, but you've got to really want it. When you're not far off buying a Ferrari California T or Aston Martin V12 Vantage S for the money, you'll need a real yearning for the three-pointed star to go this way. And if you do, good luck to you - you've probably worked quite hard to get here.

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 SL has always been completely unapologetic about its size and seems to be designed to accentuate rather than hide its length and width. The long bonnet screams power and prestige, and get out of my way, and is reminiscent of the little-loved McLaren SLR project of some years ago.

The size of the Mercedes logo on the huge front grille leaves you in little doubt about the brand of car that’s about to pass you at speed and some might say (okay, I would) that its large surface area is a little vulgar.

Like the SLR, the design doesn't seem to have a particularly cohesive strategy, with a number of Mercedes elements from around the traps that climb over each other. Roof up it looks awkward because of the gigantic posterior while with the roof down it looks overly long and, again, tail-heavy.

Folding hardtops are notoriously cumbersome and need a lot of room to hide them, but the silent operation is something to behold.

Elements that are worth deleting if possible are the dodgy 'Biturbo' badges. It's that kind of bling that gets people raising their little finger at you.

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.

“Practicality” is about as relevant to this car as a code of ethics is to a drug dealer or a contract killer, because the SL63 buyer is hardly worried about cupholders and boot space. For what it's worth, there are four cupholders in the two-seater cabin (which might explain why owners aren't worried about their liquid carrying prospects) and a minimum boot space of 364 litres and a maximum - with roof up - of 504, which is actually not bad.

Cleverly, there's a little robot-operated luggage cover inside the deep boot that stops your gear from being crushed when the roof goes down.

There's also space in the long doors where you might secrete a bottle of wine that would get a NSW Premier fired if he thanks you for it, and a bin in the console to hide your phone.

It’s difficult to ponder the idea of value when a car is already approaching $400,000 at a rapid rate even before you start piling on the options. On the plus side, for a list price of $368,715 you do get an extremely long list of standard equipment.

The SL has always been completely unapologetic about its size.

Edited highlights include leather on almost every available surface, heated and cooled electric seats with a fan heater for your neck, a B&O stereo that will shatter the windscreen on request, aluminium trim that's real aluminium (mostly), Active Ride suspension, sat nav, dual-zone climate control, active cruise, LED headlights and a huge swag of safety gear.

The 12-speaker stereo also has DVD, limited smartphone integration via Mercedes' COMAND system, a seven-inch screen and, of course, Bluetooth.

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 SL63 is powered by Mercedes’ increasingly famous V8, with two turbos along for the ride to add oomph and cut the car's famous consumption, at least slightly. The 5.5-litre unit produces a massive 430kW and a scarcely believable 900Nm of torque.

All of that heads rearward via a seven-speed dual-clutch transmission that helps sling the 4.6m, 1848kg machine to 100km/h in 4.1 seconds.

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. 

Much as is the case with the price, there's no real way to soften the blow here - the SL63 drinks like a footballer on Mad Monday, except it does it every day. The official combined cycle figure of 10.2L/100km is quite easy to double, as we did, averaging 21L/100km in mostly flowing suburban traffic. In the car’s defence, the accelerator pedal spent a good deal of time near the firewall.

The SL does have stop-start to help reduce its considerable environmental impact.

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.

There are a number of impressive things about the way the SL drives. Firstly, astronauts will be familiar with the galactic thrust of the V8. It seems endless, seamless and ready to sling the big coupe into the outer atmosphere. Few engines of any kind can match the relentless go on offer in the SL and much of the credit should go to the seven-speed twin-clutch transmission.

When you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops.

Containing a torque figure like the twin-turbo V8's requires a lot of electro-trickery to stop you from being launched off the road. The great thing about all that stuff is that it works unobtrusively and smoothly.

Mashing the carpet in an SL without traction control would create much sound and smoke but little forward progress, such is the twist on tap. The SL has a range of modes from full-nanny (which is meant to keep you on the slippery Alpine road you've chosen to get you to some Swiss ski resort) while turning the dial all the way around to Race loosens the bonds.

It's in this mode you'll have the most fun and it does seem that the intermediate settings are a bit of a waste of time. Race mode does little to diminish the amazing ride quality provided by the active suspension setup, but relaxes the reins on the huge rear tyres. Exiting roundabouts is suddenly a huge laugh, with the tail cheerfully breaking traction and the two-mode exhaust thundering in a most pleasant way.

Better still is that when you jump on the brakes and shift down, the exhaust keeps the show going with angry crackles and pops, with more on the way when you lift off. There's little to match the aural pleasures of a properly tuned V8 and Mercedes has resisted the temptation to quieten it down on the outside and generate a fake noise for the inside. Although that would be stupid in a convertible, if you think about it.

The SL63, despite its AMG badge, isn't about all-out handling, of course. The Ferrari California would definitely show it how it’s done on a winding country road. The SL is more about flow, building momentum and rarely shifting down to second gear. The monstrous torque is enough to keep things rolling but should you wish for a bit more of the exhaust bellow, second is there for the taking.

Hustling the big convertible feels wrong, not because it can't do it, but because it's not really what it's for. Having said that, it offers a kind of fun that nothing else on Earth will provide, not even a Bentley GTC.

With the roof up, the SL63 is a quiet place but not remarkably so. The huge sticky tyres do the cabin's hush no favours, with an annoying roar on a wider range of surfaces than you might expect.

Roof down, it's hardly a paragon of virtue. A lot of wind noise reaches the cabin, even well below the huge speeds the SL can reach. So if you want to talk, it's windows up you'll need to deploy the mesh screen that bridges the roll hoops.

Six airbags, ABS, stability and traction controls, blind-spot sensor, lane-departure warning, brake assist, active safety bonnet, lane-keep assist, driver attention detection, AEB.

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.

The SL63 is covered by Mercedes' three-year/unlimited kilometre warranty. And, er, that's it.
