Mercedes-Benz G63 vs Volkswagen Passat

What's the difference?

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.

I so enjoyed driving the Volkswagen Passat 206TSI R-Line. It's a roomy wagon that should fit a lot of different types of families. It still has sporty performance that will entice even the most reluctant family car buyer, so don't be turned off by its large proportions! I really like the comfort, convenience and handling of this one, so it gets an easy 8.0/10 from me.

My kid thought the blue colour was cool and loved having so many things to play with in the back seat. His only complaint was about the heavier doors but he still managed. He gives it an 8.0/10, too.

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 Passat is a large car and stands at 4708mm long, 1832mm wide and 1504mm high. The boxier rear and long nose make these proportions feel even larger.

The 2023 model doesn't see much change, if any, to the previous iteration. The exterior features the classic VW sharp pleat that runs the length of the body, slim-line LED lights and pronounce grille with lots of chrome accents found throughout.

It looks shiny, new and stylish, but not garish. You'd be proud to be seen in this.

The interior is also classically VW – sharp, a little pared back and hosting easy to see buttons and dials. The adjustable ambient lighting elevates the cabin space, as does the black headliner (R-Line exclusive).

An interesting feature is the directional air vents, the slatted design is carried the entire length of the dash which accentuates the width of the car. It all looks seamless and well thought out.

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.

A very practical family wagon with all passengers enjoying ample head and legroom.

The amenities in both rows are very good. The seats are fairly comfortable but the lumbar support isn't awesome. The massage function on the driver's side is a nice novelty but not strong enough to be called a massage. Think of it as gently stretching.

For storage, you get a decently sized middle console, dedicated phone tray, cooled glove box, drink bottle holders in each door and two cupholders.

There are plenty of charging options available for the front with two USB-C ports and a 12-volt socket. Bonus having the wireless Apple CarPlay (and Android Auto), as it's one less cable you have to worry about.

In general, I like how easy the tech is to use. The 9.2-inch touchscreen multimedia system looks great and is responsive.

It's easy to get all the connections going and you can pull the built-in satellite navigation directions through to the 10.25-inch digital instrument panel. I did miss having a head-up display this week but the info on the instrument panel is displayed clearly.

The back seat gets a couple of cupholders in the fold-down armrest and drink bottle holders in each door. It also has directional air vents with climate control, reading lights and one USB-C port for charging. However, I would have liked to have seen another charging port, to limit sibling squabbles.

There are ISOFIX child seat mounts on the outboard seats plus three top tether anchor points.

The backseat is wide enough to fit three child seats side by side if needed, and there's plenty of room for front passengers when a 0-4 rearward facing child seat is installed.

The windows are wide and offer good visibility but I really like the 142mm ground clearance. It was super easy for my six-year old to climb in and out.

The only thing he mentioned he didn't like was how heavy the doors were to operate. I don't mind this because they feel solid but they do swing wide, so be wary of letting any wild kids just hop out themselves in a crowded car park. You may get (or inflict) some dings.

The boot is a great size at 650L, with all seats in use, but if you pop down the backseats, that jumps up to 1780L.

The back seat also split-folds 40/20/40, which opens up your storage options. I enjoyed using the powered tailgate with kick function, it's handy on the grocery run.

The 206 TSI R-Line is top of a (small) two-model line-up. Our example has been finished in 'Lapiz Blue', a colour exclusive to the R-Line. Otherwise, expect a sea of monochromatic colour options.

We say top model but it's not necessarily a massive jump up in specifications from the 162 TSI Elegance, you're paying for the engine performance on this one.

This R-Line will cost you $67,790, before on-road costs. That's a $4K price hike from the 2022 model with no discernible upgrades.

And that price tag still puts it well above its closest rivals, with the Octavia RS 180 TSI being $53,090 and the Mazda6 Atenza at $52,140 (all before on-road costs).

However, you won't be disappointed with the features list with Nappa leather-appointed seat trim, R-Line stitched detailing on the floor mats and seats, electric and heated front seats, massage function on the driver's seat, a panoramic sunroof as well as wireless Apple CarPlay and Android Auto all coming as standard.

The R-Line also enjoys 19-inch alloy wheels, a full-sized spare, heat insulating tinted glass, 65 per cent light reducing rear privacy glass and 30-way adjustable ambient lighting in the cabin.

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 R-Line has a 2.0-litre, four-cylinder turbo-petrol powertrain with a maximum output of 206kW/350Nm.

That puts its engine specs 44kW up on the Elegance model and you feel that difference when you put your foot down.

The six-speed auto transmission provides surprisingly smooth shifting in most settings. The grunty engine combined with the all-wheel drive creates a sporty and purposeful driving experience.

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.

That powerful engine does cost you a little bit with efficiency. The official combined fuel figure is 8.1L/100km and real-world testing saw my figure at 8.6L.

Not too bad for the type of driving I did this week, which was a combo of open-road and urban. I wasn't scared of putting my foot down but I would expect to see a double-digit figure in an urban setting.

This has a 66L fuel tank and based on the official combined figure, you should be able to get around 815km driving range, which is great.

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 performance of this is to be commended. Powerful but poised, there's a sense of performance in reserve when you put your foot down and while still fun, it's not unbridled power.

It inspires confidence, the lower centre of gravity and firm steering meaning you tackle corners with minimum roll. You can accelerate out of a corner a little earlier than you might normally in this.

The cabin is nice and quiet with some road noise at higher speeds but not enough to intrude on chatting.

Despite suspension that feels sporty, aka stiff, the ride comfort is very good, with back seat passengers also feeling the comfort. There's not a lot of jostling in this.

Let's talk parking. It is a large car but you don't feel those dimensions when you park it.

It's very forgiving to manoeuvre with the front and rear parking sensors, crisp 360-degree view camera and tight 11.7m turning circle!

And if you're not confident it has a self-parking feature.

This has a good list of safety features with the following being standard: LED daytime running lights, lane departure alert, lane keeping aid, blind-spot monitoring, rear cross-traffic alert, 360-degree view reversing camera with dynamic guidelines, front and rear parking sensors, driver fatigue alert, and adaptive cruise control (with stop/go function).

I like the Emergency Assist feature which will provide multiple visual and sound alerts if there's no steering wheel activity detected. If there's still no driver input, the car will slow down and ultimately come to a complete stop.

The Passat's maximum five-star ANCAP safety rating has just expired and at the time of writing was yet to be retested.

The 2023 Passat has nine airbags, including side airbags for the rear outboard seats, as well as curtain airbags covering both rows.

There are three top tethers across the rear row and ISOFIX child seat mounts on the outboard positions.

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.

The Passat comes with a market standard five-year/unlimited km warranty, and roadside assistance is included for one year (through Allianz Insurance) if you get your car serviced at a VW centre.

There is a three- or five-year capped price servicing plan that can be pre-purchased and will save you money compared to the pay-as-you go option. Servicing averages $620 though, which is expensive for the class.

Servicing intervals are reasonable at every 12 months or 16,500km – whichever occurs first.
