Mercedes-Benz G63 vs Subaru BRZ

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.

The Subaru BRZ is a classic modern-day sports car that is a driver’s car through and through. This top-spec tS tester with the litany of accessories is a great example of what’s possible straight from the dealer, but it’s definitely not the best bang for your buck.

Thankfully you still get virtually every benefit the BRZ offers in the entry-level model. You’ll save thousands of dollars which you can use to pay for fuel on a road trip or modify your car exactly how you’d like.

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 Subaru BRZ has a timeless exterior design that screams dynamic sports car from every angle.

Even though the second-generation BRZ is around halfway through its lifecycle now, the design is aging like fine wine. It’s also a lovely evolution of the original which dates back to 2011.

The BRZ is low slung, has an aggressive front fascia plus the rear has prominent exhaust pipes. All of this stacks up to make a tough-looking car.

Thankfully this test example is also finished in 'WR Blue' exterior paint, which in my books is still the best colour for a Subaru performance car.

Adding all the genuine accessory goodies onto this car not only amplifies its street appeal, but also harnesses its racing intent. The carbon rear wing in particular has a swan neck design much like the Porsche 911 GT3. Many interested car-spotters craned their necks to get a good look.

Despite this, all the accessories are too flashy for my taste, especially for a car likely to be driven daily. I’d go for the stock look to retain resale, or something subtle like a small rear lip spoiler.

Inside the BRZ has all of the hallmarks of a sports car, as well. These include a steering wheel with minimal buttons, a prominent rev counter and contoured seats.

The manual gear shifter in this car is prominent and nice to hold. It’s great to still see manual options as they’re slowly but surely falling out of favour with buyers.

The manual handbrake is also a nice touch from a design perspective, but it limits overall interior practicality. More on that in a bit.

You can tell the interior is getting a little dated due to the older central multimedia system. But at the end of the day sports cars are more about the driving experience than the flashy tech.

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.

Hopping into the BRZ you’re immediately aware you’re getting into a sports car. It’s low-slung and the driving position feels like you’re almost sitting on the road. Perfect for this kind of machine.

The front seats are beautifully contoured and lock you in for when you’re driving through the twisties. Thankfully, the bolstering isn’t too aggressive and it’s still comfortable for everyday driving.

Ahead of the driver, the leather-wrapped steering wheel has a thin rim and is lovely to hold and turn. There aren’t many buttons but the few that remain are purposeful and have a lovely tactile click.

Behind this there is a 7.0-inch digital instrument cluster that permanently displays the rev counter in the middle. It’s a cool set-up that almost has a retro look to it, plus you’re able to configure the content that is displayed on the left-hand side.

Moving across, the central touchscreen multimedia system is classic Subaru. Nothing revolutionary, but I appreciate the physical shortcut buttons and dials on both sides of the screen.

It’s very easy to navigate around the screen, though as the photos show it is prone to glare, especially in bright scenarios.

Disappointingly there is only wired Apple CarPlay and Android Auto, with no wireless versions offered. You need to plug your phone in with a USB-A cable in a slot under the split-fold centre armrest.

While this means your phone will reliably charge, rather than having your phone overheat on a wireless charger, there’s no nice spot to put your phone given the physical handbrake takes up so much valuable centre armrest space.

You can put your phone in one of the cupholder spots, but when you do you don’t get a centre armrest. It’s too compromised for my liking.

While I’m on the topic of storage, there isn’t a great deal of it. There’s a small glove box and if you want, you can technically use the backseat area as they’re way too compromised for adults to fit into.

The rear seats are so small I didn’t even bother trying to fit as in my default driving position there is zero legroom. Even kids would struggle.

In terms of boot space, there is 201L available with the rear seats upright. It’s a fine space, though it’s impeded by the full-size spare wheel poking above the load floor. As a result you need to pack around the wheel.

Folding the rear seats makes the boot space more usable, though the envelope to slot things into the boot is narrow.

While the full-size spare wheel impedes the boot area, I’m glad it’s there because it’s much more usable than a dinky space-saver spare wheel or nothing at all. It gives you peace of mind in the event you have a puncture in the middle of nowhere.

The 2026 Subaru BRZ line-up starts at $47,890, before on-road costs, for the entry-level model regardless of whether you opt for the manual or automatic.

On test here, however, is the flagship tS trim which starts from $52,790, before on-roads. That's $4100 more expensive than it was when it first launched in 2024.

It’s worth noting this is overlooking the limited-edition tS Kiiro ($53,590, before on-roads) with its bright yellow paint.

As a base, the BRZ comes with a solid amount of kit. This includes 18-inch alloy wheels, LED headlights, power-folding side mirrors, an 8.0-inch touchscreen multimedia system with wired Apple CarPlay and Android Auto plus dual-zone climate control.

One of the few things missing is wireless Apple CarPlay and Android Auto. This is becoming commonplace in many cars and while it can be a hassle to plug into a USB port, it also means your phone will reliably charge.

You need to step up to the S trim if you want features like leather-accented upholstery and heated front seats. The top-spec tS in particular gains STI-tuned suspension, Brembo front and rear brakes, black door mirror covers and tS badging.

Adding to this, our particular tester comes equipped with a wealth of optional accessories. These include an STI body kit, STI alloy wheels and an STI carbon boot spoiler, totalling just over $14,500 fitted… Goodness me. For reference, the carbon rear wing is almost half of that.

Altogether, this kitted-up BRZ tS tester costs around $67,300, before on-road costs. While this is much more than the top-spec Toyota GR86 and Mazda MX-5, it’s still less than an entry-level Ford Mustang Ecoboost or BMW 2 Series.

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.

Power continues to come from a 2.4-litre naturally aspirated flat-four petrol engine producing 174kW and 250Nm.

This is mated to either a six-speed manual gearbox or a six-speed automatic transmission. Our tester is equipped with the former. Both feature a limited-slip rear differential.

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.

Subaru claims the BRZ manual consumes an average of 9.5L/100km on the (ADR 81/02) combined (urban/extra-urban) cycle.

We almost matched this during our largely urban-based testing, achieving an average of 9.7L/100km. There’s a 50L fuel tank which means there’s a total theoretical range of 515km using our as-tested fuel consumption.

A minimum of 98 RON premium unleaded petrol is required which isn’t uncommon for sports cars, but it still hurts your hip pocket nerve.

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.

This is where the BRZ has always excelled and this kitted-out tS manual is no exception.

Firing up with a cold engine, you’re immediately aware this is powered by a horizontally-opposed 'boxer' engine. It has that classic high idle that eventually simmers down once the engine has warmed up a bit.

Setting off you need to acquaint yourself with how this manual gearbox works. Every manual is a little different, however this BRZ is easy to pick up and understand quickly.

I particularly like the notchy and direct gear throw. It makes changing gears easy, fun and engaging.

If I am to be critical, the clutch bite point is a little high and there is a touch too much rev hang when changing gears, especially in the ‘Sport’ drive mode, but you get used to it eventually.

In everyday driving scenarios there is enough power available. Some more wouldn’t go astray due to the lack of a turbocharger, but this constraint makes the car more fun to drive as you have to work harder with the gears.

Speaking of, the gearing is short, which means you will be shifting gears quickly. At 60km/h, for example, the car can be driven around in sixth gear, which is clearly focused on maximising efficiency.

Once you’ve reached your set speed there’s enough torque to maintain it without having to dive back through the gears. This is nice because you don’t have to shuffle through the gears to keep up with traffic.

Out on the open road is where the BRZ comes into its own. The steering in particular highlights how balanced and poised the car feels. It’s so fun to chuck around on twisty bends and feel the weight transfer.

The STI-tuned suspension in this particular trim also highlights how sporty and dialled-in this car is. It can feel a little rough and taut on pimpled urban roads, though you need to remind yourself this is a sports car, not a comfort-oriented SUV.

In a similar vein, at higher speeds there is a lot of road and tyre noise that transfers into the cabin. This is made worse when the rear seats are folded. While more sound insulation would likely fix this, I like it being left out in the name of lighter weight (kerb weight is only 1.3 tonnes).

The current-generation Subaru BRZ hasn’t been crash-tested by ANCAP and is therefore unrated.

In 2025, the manual BRZ joined the auto version when it gained Subaru’s 'EyeSight' camera system, which brings autonomous emergency braking (AEB), lane departure warning and even adaptive cruise control. It’s rare for manual-equipped vehicles to feature the latter.

This is above and beyond the seven airbags, blind-spot monitoring, rear cross-traffic alert, lane change assist, reverse camera and tyre pressure monitoring.

It’s worth noting manual versions of the BRZ do not have any parking sensors, front or rear, as standard. Automatic versions gain rear parking sensors and a rear AEB system.

There are two ISOFIX anchors and two top-tether points for child seats in the second row, though space is rather limited.

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.

Subaru BRZ owners are covered by a five-year, 100,000km warranty which is now commonplace in the mainstream segment. Many carmakers are now extending their coverage out to seven years and beyond.

Logbook servicing is required every 12 months or 15,000km, whichever comes first. The first five services cost a total of $2595.51, which averages out to around $519 per service. For the performance car space this isn’t cheap but not as exorbitant as more premium offerings.

Subaru has a total of 128 dealers around Australia, with a spread across metro, rural and regional areas.
