Mercedes-Benz G-Class

Summary

Porsche Cayenne

Since the Porsche Cayenne turned the automotive world upside down in the early noughties, it has continued to evolve and has grown to become one of the brand's biggest sellers.

One size up from the mid-size Macan, it's problematic for hardcore Porsche-philes, but there's no doubting this five-seat SUV's success, or the fact that it helps keep the famous German sports car maker well and truly in the black.

And this is the new, third-generation version, with an all-new chassis, fresh engines, and a bunch of dynamic, safety and multimedia tech enhancements.

Mercedes-Benz G-Class

Just like smoking, base jumping and shooting rounds off in a firing range the Mercedes-AMG G63 really shouldn’t be allowed… but dammit it’s fun. Super capable over tough terrain and a bullet on the road this top-ranking G-Wagon is the rock star of the AMG line-up.

Now, you may think this new-generation G63 looks just like the old one, but it’s completely new and fun and expensive and ridiculous.
 
We piloted the G63 for the first time on Australian roads at its launch. So, what’s this tall, imposing SUV like to drive? Is the cabin as spacious as it may appear from the outside? And yes, it’s fast in a straight line, but what happens when you get to a corner?

Verdict

Porsche Cayenne7.5/10

The Cayenne may be the Porsche of SUVs, but you can't have family car size and practicality without a few concessions.

It's fast, beautifully built, and engineered with a special eye for detail, and the well specced Cayenne S is the pick of the bunch for performance and value.

But it's worth remembering the SUV bit. This Porsche is more everyday enjoyment than track day excitement.

Mercedes-Benz G-Class8.3/10

The Mercedes-AMG G63 shouldn't exist, but I'm glad it does. The previous generation was loud and fast, but had its flaws with poor ride and handling. This new gen G63 now rides comfortably and handles like a hero, while staying fast, loud and fun. 

Is the G63 the ultimate SUV? Tell us what you think in the comments below.

Design

Porsche Cayenne

The design is new yet familiar. Longer (+63mm), wider (+44mm), lower to the ground, and lower overall (-9mm), yet the wheelbase is unchanged at just under 2.9m.

All models feature LED headlights, and the Cayenne and Cayenne S are identified by their silver grille slats, with the Turbo featuring matt and high-gloss black surfaces plus larger air intakes at the front.

Car-spotters will also notice narrower side windows with a sharper decline at rear (Porsche calls it the Flyline) and the C-pillars tilting forward for a racier look.

A full width horizontal light strip across the tail sits under a clear covering above a three-dimensional version of the Porsche logo.

And wheels now range in size from 19-inch on the Cayenne, 20-inch on the Cayenne S, to 21s on the Turbo, plus optional 22s, presumably for those who drive on billiard table smooth freeways at all times.

And the Cayenne now features staggered or mixed tyres for the first time, that is fatter rubber on the back than the front.

Inside, the biggest change is the adoption of the Panamera's 'Advanced Cockpit', with the central tachometer in the iconic five-gauge instrument cluster flanked by twin 7.0-inch screens to create a blended analogue/digital version of the classic Porsche five dial layout.

Plus, there's the sleek 12.3-inch screen in the centre running everything from nav and vehicle settings to audio control and phone calls, through touch and voice.

Again, it's a direct lift from the Panamera, and the screen layout can be customised to personal preference, with Apple CarPlay standard (but no Android Auto).


Mercedes-Benz G-Class9/10

You know something looks interesting when people can't agree on whether it’s attractive or not. The CarsGuide office is divided on the new G63’s appearance with most saying it’s hot, but with a couple violently opposed to its looks.

Not that the new G63 looks different from the previous model, but that’s intentional. Mercedes-AMG knew the boxy personnel carrier-like shape was a massive part of this SUV’s appeal. The look has barely changed in 40 years. You could go back to the year 1979, push somebody into a time machine and when they fell out in the present day the first thing they’d say is: “Oh look, a G-Class”.

Despite the appearance that nothing has changed, almost everything has. The new G63 is longer, wider and taller than before at 4873mm end-to-end, 1984mm across, and 1966mm in height. 

I’m 191cm tall and there aren’t many cars that I can’t stand beside and see over. Fortunately, if I even needed to wash the roof, I could hand off the side steps, which come standard and are as functional as they are good looking.

Also coming standard are the LED running lights which ring the outside of the headlight like a futuristic lining on an old-school design, so too are the LED tail-lights. The 'Panamericana' grille with its hat-tip to racing Benzes from the 1950s is also new part of standard kit. So is the tough looking side exhaust with two pipes poking out under the pronounced running boards on either side.

Our test car was fitted with the 'Night Package' which darkens the brake lights and adds the black treatment to the spare wheel cover, the bumper and mirrors. The pack also swaps the standard 21-inch wheels for 22 AMG cross-spoke matt black rims.

The G63’s interior has also been completely overhauled and updated with a dash featuring two 12.3-inch screens, which almost look like one giant widescreen display for nav and instrument cluster. The 'Exclusive Interior Plus' package box had been ticked on our test car and that brings diamond quilted nappa leather upholstery (ours was red) everywhere.

While it’s a sumptuous, luxurious, decadent cabin it’s impossible to ignore how vertical and upright the structure of the interior is – the windscreen, the dashboard, the doors - and then you spot the giant grab hold handle mounted on the glove box and you’re reminded that you’re actually in a hardcore off-roader.

The G63 is built on a ladder-frame chassis. Again, intentional. Yes, it’s the same as the Flintstones used in their car, but it adds immense rigidity, making it a mountain-eating monster on tough terrain.

Practicality

Porsche Cayenne

Practicality highlights are more storage around the cabin, and a slide and recline adjustable rear seat.

Up front, the glove box is cooled, there are storage compartments under both seats, plus two cupholders, decent bottle holders in the doors, a 12-volt outlet (under the glove box), as well as two USB charge and connectivity ports in a generous console storage box.

Jump in the back and you'll find door bins with space for bottles, map pockets on the front seat backrests, a pair of cupholders in the fold-down centre armrest, plus two USB charge ports and a 12-volt socket in the centre console.

The rear seat's tilt and slide party trick means there's plenty of leg and headroom in the rearmost, fully reclined position. But tweak a lever on the side and a pull handle under the cushion and you can move forward (in stages) to liberate as much as 100 litres of extra cargo space over the outgoing model, while maintaining seating for five (three without legs in the extreme forward position).

Porsche's official description of the rear bench offering “two comfortable seats outside left and right and one centre seat” accurately sums up the relatively squeezy plight of the centre rear passenger.

Cargo capacity is 770 litres with the 40/20/40 rear seat upright, and a handy 1710 with it folded forward. There are four tie-down anchor points, plus a netted storage area on the passenger side, two lights and yet another 12-volt power point.

An auto tailgate is standard on all models, and a 20-inch collapsible spare (with inflator kit) sits under the rear floor.

If towing is your thing the Cayenne's weight ceiling is 3.5-tonne for a braked trailer, and 750kg unbraked. Porsche's 'Trailer Stability Management' system is standard.


Mercedes-Benz G-Class7/10

The G63 may not be as spacious as you think it is. While the ceiling is high, legroom can feel a bit restricted in the front and the back.

Riding shotgun I needed to have my front seat brought back almost to its limit so my legs didn’t feel cramped in the footwell. And while, at 191cm tall, I can sit behind my driving position with room to spare – it’s really thanks to the carved-out driver’s seat back.

Cargo capacity is far from enormous at 454 litres, but that boot space is more usable than most SUVs because of the square dimensions.

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.

That centre console bin is enormous and the rest of the storage places are great through the cabin with large door pockets and cupholders in the front and second rows.

Price and features

Porsche Cayenne

There are three models offered initially, starting with the Cayenne, powered by a 3.0-litre single turbo-petrol V6 for $116,300 before on-road costs. Then the 2.9-litre V6 Cayenne S adds a second turbo and around $40k to the price tag, coming in at $155,100.

The powerhouse Turbo tops the line-up with a 4.0-litre twin-turbo petrol V8 under the bonnet, and cost of entry sitting at $239,400.

Not a diesel in sight (for Australia) for the time being, with an E-Hybrid variant due here closer to the end of this year.

As you'd expect in this part of the market the standard equipment list is solid, with the Cayenne featuring partial leather trim, cruise control, LED headlights, daytime running lights and tail-lights, rain-sensing wipers, dual-zone climate control, privacy glass, front seats with 14-way electric adjustment and memory settings, remote central locking with 'Keyless Go', the twin digital instrument displays, multi-function sports steering wheel (with gearshift paddles), auto tailgate, 'Porsche Active Suspension Management (PASM - with adaptive dampers), 19-inch alloy wheels, and 'Porsche Communication Management' (PCM) with the 12.3-inch screen controlling nav, phone and audio (10-speaker, 150 watt and digital radio).

As well as it's more powerful twin-turbo V6 engine, the Cayenne S adds 'Adaptive PASM' (with air suspension), 20-inch alloy rims, twin dual-tube tailpipes, dynamic (directional) LED headlights, a dual-pane panoramic sunroof, heated front seats, pedal faces in stainless steel, a 710-watt Bose 'Surround Sound System' with 14 speakers (including subwoofer), and metallic paint in any one of seven colours.

Then the Cayenne Turbo piles on the power and luxury with the twin-turbo V8 joined by 21-inch alloys (in dark titanium with highly polished surfaces) including wheel arch extensions in the exterior colour, 'Porsche Active Aero' (with adaptive roof spoiler), scrolling LED indicators, 'LED Matrix' headlights, 'smooth finish' leather upholstery, 18-way electronically-adjustable 'Adaptive Sports' front seats with unique trim and fatter side bolsters, front and rear seat heating (and ventilated/cooled front seats), exterior mirrors with kerb-view parking aid, a heated steering wheel, 'cross-brushed' aluminium interior highlights, and Alcantara roof lining (cloth on base and S).

If you're ready to stump up the big bucks, that's a heap of fruit to go with this car's comfort and performance potential.


Mercedes-Benz G-Class8/10

The new G63 lists for $247,700, before on road costs, which is about $12K more than the previous model, but you’re gaining a completely new SUV with improvements in the form of two 12.3-inch screens for your instrument cluster and media, there’s the Burmester 590w 15-speaker stereo, automatic parking, AMG sports exhaust, proximity key, nappa leather interior, sat nav, TV tuner, Apple CarPlay and Android Auto, three-zone climate control, heated front seats and 21-inch alloy wheels

The Edition 1 G63 will costs you another $19,500 on top of the list price but includes the 'Night Package' which brings the black elements along with the 'Exclusive Interior Plus' package and an interior which adds carbon-fibre trim.

Engine & trans

Porsche Cayenne

The new car's engines are lifted from the Panamera, and not only feature more power than the outgoing Cayenne, but Porsche claims improved fuel economy and lower emissions.

All feature an alloy block and heads, the Cayenne's 3.0-litre, single turbo V6 delivering 250kW from 5300-6400rpm, and 450Nm from just 1340rpm all the way to 5300rpm.

This 'base' engine features direct fuel-injection, 'VarioCam Plus' (variable cam control on the inlet and outlet side, and valve-lift adjustment on the inlet side), as well as the turbo located in the engine's vee to help minimise lag.

The Cayenne S's 2.9-litre V6 adds a second turbo to deliver 324kW from 5700-6600rpm, and 550Nm between 1800rpm and 5500rpm. It's shorter stroke design helps lift the rev ceiling by 300rpm (to 6800rpm).

Then the Cayenne Turbo adds two more cylinders to pump out no less than 404kW (542hp) across a narrow plateau from 5750-6000rpm, and 770Nm between 1960rpm and 4500rpm. The V8 also locates the turbos in the 'hot vee', but drops back to 'VarioCam' (variable cam control on the inlet and outlet side) without valve-lift adjustment on the inlet side.

All models now feature an eight-speed 'shift-by-wire' 'Tiptronic S' auto transmission, with drive going to all four wheels courtesy of Porsche's Active Traction Management system. The gear set in the Turbo (including the final drive) is slightly taller, although the seventh and eighth ratios are overdriven on all models to maximise fuel economy.

Claimed 0-100km/h times (with optional Sport Chrono package numbers in brackets) are: Cayenne – 6.2sec (5.9s), Cayenne S – 5.2sec (4.9s), Cayenne Turbo - 4.1sec (3.9s).

And if you have a very long driveway, leading up to your (presumably) very large house, you'll be pleased to know maximum velocity for the Cayenne is 245km/h, rising to 265km/h for the S, and a stonking 286km/h for the Turbo.


Mercedes-Benz G-Class10/10

New engine, more grunt. Gone is the old 5.5-litre V8 turbo and in is the new twin-turbo 4.0-litre V8 (the same engine used in the Mercedes-AMG GT) with stacks more torque and the same power, at a whopping 430kW and colossal 850Nm.

How fast is the new G63? First, can I point out it weighs 2.5 tonnes, so take that into consideration. Second, it can nail 0-100km/h in 4.5 seconds. That is incredible.
 
Shifting gears seamlessly is a nine-speed automatic transmission.

The G63 is four-wheel drive and has three 100 per cent differential locks and low-range gearing. 

Fuel consumption

Porsche Cayenne

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle ranges from 9.2L/100 km for the Cayenne (emitting 209g/km of C02 in the process), to 9.4L/100 km for the Cayenne S (213g/km), and 11.9L/100 km for the Cayenne Turbo (272g/km).

All models feature auto start-stop (with coasting), your only fuel option is 98 RON premium unleaded, and you'll need 90 litres of it to fill the tank.


Mercedes-Benz G-Class7/10

Oh, come on, you don’t want to know this… skip to the next section.

You’re still here. Okay then, it’s 13.1L/100km over a combination of urban and open roads. That’s under ideal conditions, too. Our car was going through premium unleaded at about 16.0L/100km. Good thing is you have a 100-litre fuel tank.

Driving

Porsche Cayenne

The new Cayenne sits on the VW Group MLB Evo platform, which also underpins the Audi Q7, Bentley Bentayga, Lamborghini Urus, and the soon-to-arrive new generation VW Touareg.

It uses a lot of aluminium and lightweight high-strength steel which, in concert with the alloy body panels, makes the car not only stiffer, but lighter by up to 65kg.

We've driven each model over a two-day launch program in The Barossa Valley in South Australia, and can confirm the base Cayenne is quick, the S is properly fast, and the Turbo is ballistic.

The transmission is a conventional eight-speed auto, rather than Porsche's PDK dual-clutch, and shifts are quick but smooth in normal mode, transitioning to a sharper, even more precise response in Sport or Sport Plus.

Porsche stands proudly on its reputation as a great sports car maker and says the Cayenne fits easily into that context. But let's face it, this is a two tonne SUV, and while it's dynamically outstanding, it's no 911.

All models feature multi-link suspension front and rear including active dampers, with varying levels of suspension sophistication as you walk up the range, to three chamber air suspension on the Turbo.

On quick twisting B-roads it's fast, in the case of the Turbo, bloody fast. It grips hard thanks to fat Z-rated rubber and active drive distribution makes sure it puts its power down perfectly. But no matter how sophisticated the suspension tech, it still feels large and relatively top heavy.

The electromechanical steering is light, and while it's accurate, no matter which mode you're in road feel is modest.

Not surprisingly, the ride firms up in tune with sportier drive modes, but in Comfort, even the Turbo on 21-inch rims, soaked up the irregularities of at times choppy rural roads with surprising ease.

Given the car's mass and performance potential braking is an understandable priority, with even the base model featuring big ventilated rotors all around with four piston calipers at the front and two at the back.

The S ups that to six piston front and four at the rear, while the Turbo debuts Porsche's 'Surface Coated Brake' a Tungsten-Carbide coating on the discs and special pads for longer life and less dust. Of course, the front calipers are 10-piston with four at the rear (and they're white just to prove brake dust isn't a problem).

In typical Aussie conditions these monster brakes are like cracking a walnut with a sledgehammer. Stopping power (on all models) is immense, and pedal feel is agreeably progressive.

We also headed off-road through rutted dirt and rocky climbs, and with five drive and chassis modes at its disposal the Cayenne ate it up.

The different off-highway modes ('Gravel', 'Mud' and 'Rock') will lock and unlock the centre and rear diff as required and the adjustable hill descent control made crawling down steep slopes a breeze. You can even option up an 'Offroad Package' bringing extra protection for vital components, as well as off-road specific info in the PCM and a compass display on the dash.

If you need to think about the dips and climbs on your country retreat, or maybe just the pitch of your driveway, the Cayenne and Cayenne S's approach and (with the Turbo in brackets) is 25.2degrees (23.3), ramp over is 18.7degrees (16.7), departure is 22.1degrees (20.4), ground clearance measures 210mm (190mm), and fording depth is 500mm (475mm).


Mercedes-Benz G-Class9/10

Have you ever driven a G-Class before? Nope, well then have you ever ridden an elephant, then? Passed time hanging out on the roof of your house just drinking beer? Sat on somebody shoulder’s in a game of swimming pool volleyball? 

Okay, well you feel very high up and the bonnet stretches out before you like the hood of Mack truck, and that’s when you realise those weird-looking indicators on the guards double as signposts letting you know where the edges are.

But even then, it doesn’t feel big to drive, even the cabin feels a bit tight up front.

What it does feel is fast. Very fast. Dab the accelerator and the nose rises up and you better be pointing in the direction you want to go, because hold the pedal down and the G63 will yank you down the road at warp speed.

Acceleration isn’t supercar brutal by any means, but how it gets there is roaring through that side exhaust like a Viking running into battle, after waking up on the wrong side of the bed. With the windows down its deafening, but in good way.

Complaints about the old G63 centred around steering, ride and handling or more specifically the absence of those three things. In this new generation G63 those pain points have been addressed by replacing articulating ball steering with electric power steer, swapping the live front axle for independent front suspension and revising the chassis rails.

Now, the G63 can go around corners – incredibly well. Our test track was Victoria's Great Ocean Road, and if we were in any other large SUV, they would have been fishing us out of Bass Strait.
 
Steering is now accurate and progressive; the front end feels pointable and light.

Comfort drive mode is too comfortable for me, giving the ride a wafty bounce. Sport mode firms the dampers for good handling but keeps the ride comfortable, which adding weight to the steering. Sport Plus firms the adaptive dampers further and combines great cornering without an unbearable ride.

The G63 isn’t a vicious animal unlike some big grunt sports cars, but you have to keep reminding yourself you can’t drive it like one. Not because it will bite you, but because it’s 2.0-metre tall, 2.5-tonne metal box. A hilariously fun one.

Safety

Porsche Cayenne

Active safety systems include the usual suspects like ABS, ESC, and traction control (ASR), with the addition of other features under the 'Porsche Stability Management' umbrella, including ABD (torque vectoring by braking), and MSR (prevents slip on the drive wheels produced under engine braking)
There's also AEB (although the Porsche system doesn't bring the car to a complete stop), 'Park Assist' (front and rear) including 'Surround View', 'Lane Keeping Assist', 'Lane Change Assist', and tyre pressure monitoring.

But if all else fails passive features include an active bonnet (activated by pedestrians, cyclists, etc detected by the front camera), driver and front passenger airbag, knee airbags for the driver and front passenger, front side airbags, rear side airbags and full-length curtain bags.

There are three top tether points across the back seat with ISOFIX anchors on the two outer positions. ANCAP hasn't assessed the third generation Cayenne so far, but its Euro NCAP affiliate awarded a left-hand drive, 3.0-litre diesel model a maximum five stars in 2017.


Mercedes-Benz G-Class9/10

The G63 has the maximum five-star ANCAP rating and along with nine airbags comes with AEB, lane keeping assistance, blind spot warning, traffic sign recognition and adaptive cruise control.

For child seats you’ll find three top tether points and two ISOFIX mounts across the second row.

Obviously, there’s a full-sized spare wheel. Don’t make me point it out.

Ownership

Porsche Cayenne

The Cayenne is covered by Porsche's three year/unlimited km warranty, with paint covered for the same period, and a 12-year (unlimited km) anti-corrosion warranty also included.

Porsche Roadside Assist provides 24/7/365 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer, and the main service interval is 12 months/15,000km.

No capped price servicing is available, with final costs determined at the dealer level (in line with variable labour costs by state/territory). Indicative scheduled costs for the first four years/60,000km line up as: 12 months/15,000km (annual) - $695, 24 months/30,000km (intermediate) - $695, 36 months/45,000km (annual) - $695, and 48 months/60,000km (major) - $1300, for a total of $3385.


Mercedes-Benz G-Class7/10

The G63 is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. The pricing plan for servicing will cost you about $4000 over three years.
