Porsche Macan vs Mercedes-Benz G-Class

What's the difference?

Competent and comfortable, the Macan T delivers that amazing Porsche double act of crisp dynamic response without compromising refinement. It’s well equipped for the price, neatly packaged, and entertaining to drive. But there are holes in its armour. Active safety comes up well short and a three-year warranty now stands out like a sore thumb. It’s good, but could be better.

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.

Michael Mauer has been Porsche’s chief of design for close to 20 years, overseeing the look and feel of every product the brand has produced in that time. And he’s been successful in massaging particular forms and signature elements to work across the line-up. 

For example, you can see more than a hint of 911 in the Macan T (and other models, for that matter), from the elongated four point headlights, to the gentle curve at the rear of the roofline, as well the distinctive tail-light treatment.

Since launching internationally in 2012, the Macan has been tweaked in 2016, before a full-blown refresh in 2021. Mauer and his team have somehow transplanted a Porsche sports car’s stance and personality to this mid-size SUV, which incidentally boasts a drag-coefficient of 0.35 (not bad, but still a fair way off the 911’s 0.29). 

For car-spotters keen to tick the Macan T off their list, the thing to look out for is exterior elements finished in ‘Agate Grey Metallic’. Specifically, the middle section of the front apron, the side ‘blades’ running across the lower section of the doors, the roof spoiler, and the exterior mirrors (including their V-shaped bases).

Then it’s all about high-gloss black on the side window trims, exhaust outlets and parts of the rear diffuser. But the biggest giveaway is the Porsche logo and model designation finished in, you guessed it… Agate Grey Metallic.

In looking at the Macan T’s interior design it’s important to call out our test car’s optional leather trim package ($3280) and carbon interior trim package ($1600), combining to dial up the cabin’s racy, premium feel.

A relatively simple dash design incorporates Porsche’s iconic three-dial instrument layout housed in a compact, curved binnacle. On the right-hand side a 4.8-inch configurable info display takes the place of what would have traditionally been an analogue gauge.

The wide centre stack houses a 10.9-inch media display above (big tick) physical ventilation controls. A sloping centre console is filled with touch controls under a piano black finish. Looks good in the showroom, but fingerprints are its enemy.

The front sports seats feel as good as they look, and overall the design is premium, functional and focused.

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.

At just over 4.7m long, around 1.9m wide, and a fraction more than 1.6m tall the Macan is a large medium-size SUV, but inside it feels more like the former than the latter.

Plenty of breathing space for the driver and front passenger, with a broad centre console dividing the space. Storage is good, too.

The glove box is a handy size, there’s a decent lidded box between the seats (that doubles as a centre armrest), as well as two large cupholders in front of it, and a handy oddments tray just behind the gearshift. Big door bins with space for large bottles are also a welcome inclusion.

Swapping to the back seat, sitting behind the driver’s seat, set to my 183cm position, I had heaps of leg and headroom. There’s even enough room for three full-size adults on short to medium journeys, although the full road trip experience would be too close for long-distance comfort. A trio of up to teenage kids will be laughing. 

For storage there are two cupholders in the fold-down centre armrest, bins with enough room for large bottles (and a bit more) in the doors, and adjustable air vents with temperature control as part of the three-zone climate-control system. No map pockets on the front seat backs, though.

Power and connectivity runs to a 12-volt outlet in the front centre console and another in the boot, as well as a SIM and SD card slot in the front, supplemented by two USB-C jacks in the front and another pair in the rear. 

Speaking of the boot, it’s generous, with 488 litres (VDA) available with all seats up (measured to the upper edge of the rear seats). Fold the 40/20/40 split-folding rear seat and that number grows to 954 litres. Measure volume right up to the roof in that configuration and you have no less than 1503 litres to play with.

The boot space is properly illuminated, there are four tie-down anchors to help secure loose loads, and a small netted space lurks behind the wheel tub on the driver’s side.

Our test car was fitted with the optional adaptive air suspension system ($2790) which allows lowering of the car’s rear when stationary to make shuffling heavy loads into the back easier. And the standard auto tailgate is super helpful.

Maximum towing capacity for a braked trailer is 2.0 tonnes (towbar preparation and ‘Trailer Stability Management’ are standard), and the spare is a space-saver.

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 Macan T is powered by a version of the VW Group’s ‘EA888’ turbo-petrol, four-cylinder engine, used in a host of Audi, Seat and Skoda models, as well as, most-notably, the previous generation VW Golf Mk7 GTI.

The 2.0-litre, all-alloy unit uses a combination of port and direct fuel-injection, plus variable cam timing on the inlet and exhaust side to produce 195kW from 5000-6500rpm, and 400Nm across a broad plateau from 1800rpm right up to 4500rpm. The rev ceiling sits at 6800rpm.

Power goes to all four wheels via a seven-speed dual-clutch automatic transmission and an electronically-variable multi-plate clutch.

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.

Porsche’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle for the Macan T is 9.5L/100km, the 2.0-litre four emitting 217g/km of CO2 in the process.

Over a week of city, suburban, and some freeway running we saw a dash-indicated average of 10.2L/100km. A solid, if unspectacular result for a close to 1.9-tonne SUV. 

Auto start-stop is standard, but pricey 98 RON premium unleaded is required, and you’ll need 75 litres of it to fill the tank.

Using the official number that translates to a range of 789km, which drops to 750km using our real-world number.

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.

Porsche claims the Macan T will accelerate from 0-100km/h in a suitably rapid 6.2 seconds and mid-range pulling power is healthy, with maximum torque available from 1800-4500rpm.

Worth noting, however, if you’re looking for ‘special event’ engine and exhaust noise to accompany that progress you may be left wanting more aural oomph. Despite our test car’s optional sports exhaust ($3080), this four-cylinder can’t match the relative drama of the Macan S and GTS’s twin-turbo V6.

The upside of that difference is the 2.9-litre V6 puts an extra 59kg on the Macan’s front axle, so the 2.0-litre T feels lighter and that bit more responsive when the road starts to twist.

Suspension is multi-link front, trapezoidal link rear, and the Macan T is also fitted with stiffer, model-specific sway bars to manage body roll. Ride height is also 15mm lower than the base 2.0L Macan.

Steering is quick, road feel is good, and despite the standard 20-inch rims, ride comfort is excellent. This is Porsche’s long-established, engineering party trick, combining plush compliance with sharp dynamic response, even in a high-riding SUV. That said, the optional adaptive air suspension fitted to our test example, is $2790 well spent.

The drivetrain is set up with a RWD bias, and standard rubber is Michelin’s high-performance SUV tyre, the Latitude Sport 3 (265/45 fr / 295/40 rr). They grip hard while remaining quiet, and the Macan T is an entertaining drive on a quiet B-road.  

Braking is by vented discs all around (350mm fr / 330mm rr) with beefy four-piston alloy monobloc fixed calipers up front and floating singles at the rear. Stopping power is reassuringly strong and progressive, especially important given the car’s 2.0-tonne (braked) towing capacity.

For more adventurous drivers, ground clearance is 187mm, while the approach, departure and ramp angles are a relatively modest 15.8, 15.4, and 21.0 degrees, respectively.

In the less challenging terrain of a shopping centre car park the standard reversing camera and 360-degree surround view make manoeuvring into tight spaces a stress-free operation.

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.

Porsche is the last brand standing in the local mainstream sports luxury market, offering a three-year, unlimited kilometre warranty when the rest of the segment has moved on to five-year, unlimited km cover. 

The good news is paint is covered for three years and a 12-year (unlimited km) anti-corrosion warranty is included (the Macan’s body is fully galvanised). 

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.

Servicing is required every 12 months or 15,000km, which is less in terms of mileage than some others in the category.

With Porsche, final costs are determined at the dealer level (in line with variable labour rates by state/territory), but indicative pricing for the first five years is: 12 months/15,000km (annual) - $695, 24 months/30,000km (inspection) - $1300, 36 months/45,000km (annual) - $695, 48 months/60,000km (inspection) - $1300, 60 months/75,000km (annual) - $695. Not exactly cheap, but not outrageous in this part of the market.

A brake fluid flush is recommended every two years ($290), as well as spark plugs ($450), air filter ($200), and transmission fluid and filter ($850) every four years. So, be ready for those ‘extras’.

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.
