What's the difference?
The fastest-accelerating and most powerful series production AMG to date isn't some slinky supercar, it's a truly enormous four-door, four-seat barge that weighs just a smidge under 2.4 tonnes.
Surprised? Welcome to the wonderful world of electrification, one where manufacturers can produce physics-bending performance by combining an internal combustion engine (ICE) with an electric motor, just so long as they're willing to put up with some extra weight.
And so it is with the Mercedes-AMG GT63S E Performance Coupe, which is a plug-in hybrid, though perhaps not quite as you know them.
Efficiency is not the name of the game here. Performance, and lots of it, is the goal. And, thanks to the combination of a twin-turbo V8 engine and a powerful electric motor, this big beast delivers plenty of it.
Bentley has been building cars for more than 100 years, but the famous British brand was re-born 20 years ago when it launched the Continental GT.
The sporty coupe and convertible reinvigorated the brand, returning it to its former glory days when it made cars that were dynamic and not just big and luxurious.
Now onto its third generation, the Continental GT has not only helped Bentley re-establish itself but also become a modern motoring icon.
Which is what the company wanted, an iconic model, like the Porsche 911 that could be a flagbearer for the brand.
Like the 911, this latest iteration is available in multiple forms, and we’re testing the Continental GT S Convertible, a two-door, four-seat grand tourer - with an emphasis on the ‘grand’.
This is no Lotus, but damn if it ain't a hell of a good time, and proof positive that electrification can enhance the V8 experience, rather than ruin it.
It may not come cheap, isn’t ideal for family buyers and will have you visiting the petrol bowser regularly, but it’s still hard not to love the Continental GT.
It’s an over-the-top car in so many ways, from the dramatic styling to the plush and pampering interior to the effortlessly powerful engine, this is a car that is a pleasure to drive 10km or 10,000km.
It’s certainly not cheap, especially if you start diving into the options list, or the even more costly Mulliner program, but price is relative, of course, and for Bentley buyers purchasing one of these cars isn’t about getting a ‘bargain’ but instead it’s about experiencing the finer things in life.
It's a mean, but somehow still sleek, looking beast, this big AMG, but it's also immediately recognisable as a thing of intent.
Up front, there's the huge vertical-slat grille that looks like it drove straight out of a Stephen King novel, a massively domed bonnet, and these vacuum-like side intakes that look like they could suck in stray animals.
Then, at the back, there are twin dual-pipe exits (for four in total), and an automatic wing that pops out of the rear bodywork. And all of that's capped off with these massive 21-inch forged alloy wheels hiding golden ceramic-composite brakes.
Mean, yes, but not quite as aggressive as you might expect the most powerful AMG to date to come across, perhaps.
Inside, it's more subdued again, with the AMG presenting a pretty passenger-friendly space, with all the Benz tech you'd imagine, including the massive screens, and — thanks to its air suspension and drive modes — the ability to tailor the ride to your liking, meaning a comfortable and premium experience, despite the power under your right foot.
The most interesting aspect of the third-generation Continental GT design is how similar it looks to the first-generation model launched 20 years ago.
Put the pair side-by-side and you’ll notice the latest model is more refined and features crisper lines and more intricate details, but the overall shape and design themes, such as the grille, headlights, etc, bare a similar family resemblance.
This is a deliberate act from Bentley, choosing an evolutionary styling approach for the Continental GT in the same way Porsche has approached the 911.
As for the specific details of this particular Continental GT S model, there are some key differences between it and the standard GT and GT Azure models that sit beneath it in the range.
The most notable - even if it is slightly harder to spot on our black test car - is a ‘black pack’ that swaps all the chrome finishes on the exterior to black.
This includes the grille, headlight surrounds, lower bumper grille, window surrounds, door mirror caps and the exhaust tips. The S also adds black sports sills and black-painted alloy wheels.
It's not overly practical, given its size, with AMG locking in a four-seat configuration with a fixed rear pew that limits boot space. You can get folding seats, but only as part of an option package.
What you're left with is a vehicle that stretches 5054mm in length, 1953mm in width and 1447mm in height, but that serves up rear seating for only two – albeit very comfortably – and, because of the electric battery and motor being housed at the rear, boot space of just 335 litres.
There is triple-zone climate control, and the rear seating is lounge-like and luxurious, while the up-front space is ample for two full-size riders, too.
There's no spare, with AMG's 'Tirefit' puncture repair system on board.
As mentioned earlier, the Continental GT is a two-door, four-seat grand tourer, but while it’s certainly grand, calling it a four seater may be a stretch.
There are two small seats in the rear that can be used if absolutely necessary but anyone in the back won’t feel like they’re in a luxury car because they’ll be cramped for space - even with the roof down.
You could pop small kids in the back in a pinch (and there is a pair of ISOFIX anchor points) but the Continental GT is hardly a family car.
In fact, the Flying Spur is a four-door sedan built on the same underpinnings as the Continental GT, so Bentley does have family buyers covered.
So, let’s keep our attention on the front seats, which is where you want to be in this grand tourer. The seats are comfortable and offer fantastic support, thanks in large part to 12-way electronic adjustment.
To help you enjoy your convertible with the top down regardless of weather, the seats are heated and available with a vent to blow warm or cool air onto your neck.
The seats are just the start, the whole cabin is a blend of modern technology and classic luxury elements.
There’s the media touchscreen, but there’s also a physical button for most functions, so it’s a busy layout but one that will likely appeal to Bentley’s older clientele.
Our test car was fitted with not only the optional sound system but a rotating display, so you can hide the screen away when you’re not using it.
Overall the build quality and attention-to-detail is exceptional, as you’d expect for a car at this price. And it’s really one of the main reasons you buy a Bentley, because it has a level of luxury and quality above brands like Mercedes-Benz and Porsche.
There's no escaping the fact that a big number has been applied this AMG E Performance model in Australia, with the GT63S commanding $399,900, before on-road costs, and before you start selecting option packs.
Obviously performance is what you're really paying for here, but there are lots of niceties included, too.
They include an electric glass sunroof, 21-inch forged-alloy wheels with ceramic composite brakes, rear-axle steering, puddle lighting, power-closing doors (only sealing, not full hands-off closing), LED lighting, and an auto rear wing that retracts back into the body work at the rear.
Inside, there are twin 12.3-inch screens with Apple CarPlay and Android Auto, a Burmester sound system, Nappa leather seats front and back (which are heated and cooled in the front, and which offer a massage function), and three-zone climate control.
You can then spring for the 'AMG Night Package' ($3490) which adds the 'AMG Night Exterior Package', different 21-inch wheels in matt black, dark tints on the rear glass, black badging and dark chrome on the grille.
Then there's the considerably more expensive 'AMG Carbon Fibre Package' ($18,490), which gives you the carbon exterior package, carbon inserts in the side skirts, and more carbon on the front wing trim, the mirror housings, the rear wing (which is now fixed) and in the cabin.
There is more, of course, but we'll get to them under our performance, driving and safety sections.
Naturally the Continental GT doesn’t come cheap, with the range beginning at $430,300 (all priced exclude on-road costs) for the ‘entry-level’ coupe model.
The Continental GT S Convertible we’re testing here is priced from $568,400.
But with cars like the Bentley, the list price is really only the starting point as the company offers a huge array of ways for owners to personalise their cars and this can make a dramatic difference to the cost.
For example, our test car featured several additional extras including its interior leather colour combination, upgraded 1500W 16-speaker Bang & Olufsen sound system, larger 22-inch alloy wheels and more, which pushed the price to $667,806.
In terms of personalisation, the sky's the limit. Or perhaps to be more precise, your bank account is the limit. That’s because Bentley’s Muliner department can create unique colours, leathers, trims, you name it, whatever your heart desires is yours - as long as you can afford it.
Even if you don’t want to go down that path there’s still plenty of choice, with the Continental GT available in 16 standard body colours plus an extended range of off-the-shelf hues.
There are three standard roof colours with four optional colours, as well as five interior leather choices and 11 different veneer 'species' to select from.
Focusing on the equipment that comes standard with the Continental GT S, this includes 21-inch alloy wheels, air-suspension, full LED matrix headlights, a 650W 10-speaker sound system and a 12.3-inch multimedia touchscreen which incorporates navigation, Bluetooth and WiFi streaming, digital radio, Apple CarPlay and even a CD slot (which is a rare find these days).
It's not just what's under the bonnet, but what's at the rear axle, too.
But let's start at the front, shall we? Here, a familiar twin-turbo V8 engine lurks, producing a potent 470kW and 900Nm, which is fed through a nine-speed automatic, complete with paddle shifters and several drive modes, including the traction-limiting 'Race'.
But that is then joined at the rear by an electric motor with its own two-speed transmission, and which produces 70kW and 320Nm – or up to 150kW for 10-second blasts under heavy acceleration.
Combine both, and you're tapping into around 620kW and in excess of 1000Nm, enabling a sprint to 100km/h in just 2.9 seconds, and a flying top speed of 316km/h.
Bentley is renowned for its big, powerful engines, specifically its unique W12. That’s available in the top-of-the-range Continental GT, but the S model we’re driving is motivated by a 4.0-litre twin-turbo V8.
It may not be what Bentley is famous for, but it’s a fantastic engine in its own right and it’s paired to a well-matched eight-speed automatic transmission and an active all-wheel drive system.
Making a very healthy 404kW and 770Nm it has no trouble getting such a big car moving.
Bentley claims the Continental GT S will run 0-100km/h in just 4.1 seconds, which is very rapid and particularly impressive when you realise this car weighs 2335kg.
Fuel efficiency is surprisingly impressive for a vehicle this big and powerful, with Mercedes claiming 7.7L/100km and 175g/km of CO2 on the combined cycle.
Helping that is a the 6.1kW battery, which delivers just 12km in all-electric driving range, but helps reduce overall fuel use.
This AMG is AC power only, meaning you can't recharge using fast chargers, but the brand says its secret trick is its ability to recharge itself using captured kinetic energy incredibly quickly – largely negating the need to plug in unless you want to unlock that EV range – with Merc suggesting that, on a race track for example, the battery will discharge and charge itself continuously as you're lapping.
If you’re looking for a fuel efficient car or are worried about the price of premium unleaded at your local service station, the Continental GT is not for you.
In an entirely unsurprising way, this two-tonne, twin-turbo V8 luxury car is not a fuel-sipping proposition.
Even the official combined urban/highway cycle is 12.5 litres per 100km, which is thirsty.
But if you’re spending most of your time around town, rather than driving to your country weekender, you’ll probably be looking at returns in the mid to high teens, based on our experience.
We saw an average of 16.7L/100km on the car’s long-term trip computer that included more than 1400km of driving.
Fortunately it has a 90-litre tank, which translates to a theoretical driving range of 720km - as long as you can hit the official claim.
There's a lot of big numbers surrounding the Mercedes-AMG GT63S E Performance, but let me throw another one at you – 245km/h.
That was the high score I saw pop up on its digital speedo as the big and electrified Mercedes flew down the main straight at Sydney Motorsport Park (formerly Eastern Creek), before my courage ran out and my foot found the brake.
That kind of velocity is mind-bending in a vehicle this big, and so is the way that power is delivered, with the AMG's big brain deciding how and when to maximise power from the engine and electric motor to deliver a constant surge of torque that shoves you back, and the GT63S E Performance into the future.
But big acceleration is hardly surprising with that much power. What is a little more impressive is how easy this four-door supercar is to wrestle around a racetrack.
Sure, the feeling-out process is a little more involved, as you figure out how and when you'll feel the weight shifting, and as your brain struggles to compute how what's happening is even possible, but after a couple of laps the AMG settles into an easy, flowing rhythm that, while never feeling light on its feet, also doesn't feels like you're piloting a bus.
At least part of that is down to the wizardry on board, like the 'AMG Air Suspension', the rear-axle steering and the limited-slip diff, all of which combine to make the GT63S feel tighter and sharper than it would otherwise.
But it's also partly down to the prodigious power on offer – perfect corner entry and exits are less relevant when you have a cruise missile strapped to your right foot that doesn't just quickly make up for any driver errors, but shrinks the space between corners to the blink of an eye.
Yes, it's heavy, and there isn't much that's pure about the go-fast experience, but it left an ear-to-ear grin on my face, and isn't that priority one for any new AMG?
How does it drive on the road? That I don't know, as this was a track-only drive day. But we will get one on a proper test soon and let you know.
There’s a duality to the driving experience of the Continental GT, as it manages to blend its obvious luxury focus with a genuinely dynamic edge that makes it a true grand tourer.
The combination of the powerful engine and air suspension means it possesses a laid back personality and effortless nature around town.
The engine delivers its performance with ease, moving this big car rapidly whenever you put your foot down, so you can jump into gaps in traffic or make a brisk getaway from the lights.
It soaks up all the bumps and imperfections on the road with minimal fuss, too, despite our test car riding on 22-inch wheels, so you feel cosseted inside the plush cabin.
However, if you find yourself on the open road, the Continental GT S is equally at home.
Dial up the ‘Sport’ drive mode and the engine feels more responsive, the steering is more direct and the suspension is more taut but still compliant.
It makes this a really fun car to drive on a fast, sweeping rural road, where you can let the engine stretch its legs.
Because of its size it’s not as enjoyable on a twisty road with lots of changes of direction, though.
But for enjoying an opulent daily commute or a weekend drive in the countryside the Continental GT S is a great companion.
The GT63S E Performance is yet to be crash-tested (probably something about each one costing about the same as small apartment), but it does come pretty comprehensively loaded with safety kit.
That includes the standard 'Driving Assistance Package Plus', which delivers active cruise control, AEB, 'Active Steering Assist', 'Active Lane Change Assist' and nine airbags.
Despite costing more than $500,000 there are still several optional safety features for the Continental GT, which is surprising and disappointing.
There is a decent level of standard equipment, including four airbags - driver and front seat passenger, as well as side - and a reversing camera, as well as active safety items including pre-collision warning, collision prevention assist, rear cross-traffic alert and multi-collision brake.
However, equipment that is standard on much cheaper cars that’s optional on the Continental include active lane keeping assist, adaptive cruise control with 'Traffic Jam Assist', traffic sign recognition, pedestrian warning, reversing traffic warning and top view cameras.
These are available in optional packages, but it’s not unreasonable to expect every safety feature Bentley offers as standard given the asking price.
As for an ANCAP safety rating, the Continental GT doesn’t have one - again, largely because of its price.
As ANCAP testing requires multiple vehicles to be destroyed it’s not financially viable to test all models in this premium market, so cars from the likes of Bentley, Porsche, Rolls-Royce and others rarely have an independent safety rating.
The GT63S E Performance is covered by Mercedes' five-year, unlimited-kilometre warranty, and you can pre-pay your service costs to keep the prices down.
Service pricing for the electrified model is yet to be confirmed.
Another surprising feature of the Bentley range is the company’s three-year, unlimited kilometre warranty, which feels surprisingly short in this day and age - especially for a brand that takes pride in its carefully built cars.
There is a 10-year warranty available as an optional extra, but it feels like that should be standard if the company is willing to stand by its products anyway and owners are paying such a premium for their cars upfront.
The good news is all Bentley models are covered by a five-year servicing plan (intervals are 12 months/16,000km) which is included in the cost of the car.
As you should expect from such a premium brand, the local dealer will arrange to collect and return the car when servicing is required, and a loan car can be arranged if required.
