Bentley Continental vs Mercedes-Benz S560

What's the difference?

Any fears Bentley was heading in the wrong direction by abandoning 12 cylinders for hybridisation (not that it had a lot of choice) should be totally salved by the Continental GT Speed. It is a hugely capable, fabulously luxurious and beautiful to behold grand tourer that deserves extra points for not being an SUV. It might just be the supercar you could drive every day, with no complaints.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

I don’t think I’ve ever heard so much interesting waffle about the design of any car, ever, but before we get to the wild, and wildlife, justifications for how it looks, just feast your eyes on it. 

Now, not everyone might love it, but it’s hard to imagine a huge, super coupe looking any better than this thing does. It’s no Ferrari, sure, but realistically it doesn’t have to compete with that, because it’s a cruiser as well as a bruiser, a supercar you can be quiet and comfortable in. A Rolls-Royce with rocket engines, even. 

The most obvious change, of course, is that Bentleys have had four headlights, or four eyes if you like, for so long that seeing this new one with two is a major shock, a big shift, but somehow it works.

The proportions, the elegance, the bold 'be big and bold and give no damns what anyone thinks', it’s just impressive, and the interior reflects that same, luxury ethos.

Apparently the new-look Continental is built on three design principles, the first of which is, amusingly, 'Resting Beast'. This is supposed to reflect how the Bentley looks from side on; like a tiger, stalking its prey, or perhaps resting and thinking about its prey. It’s all muscles and strength and power, but also elegance. And who doesn’t imagine tigers walking red carpets in ball gowns?

Principle two is 'Upright Elegance', and here you’re supposed to see, in the car, the strong vertical line one finds in the chest of a thoroughbred horse when it’s standing in particularly powerful way. Great. Love it.

And finally, there is the 'Endless Bonnet', which is a horizontal line that goes from the front of the car - via the bonnet obviously - and all the way to there rear, via cat-like haunches, providing an impression of “speed, even when standing still”.

Those are the bold strokes, but it’s all the little details that make it sing, like the beautiful jewellery-like look of the headlights, which are meant to resemble a tiger’s eyes. So many cats, is it any wonder I started thinking of the Bentley as a very, very flashy Jaguar?

It’s important to note that while it looks very new - and 68 per cent of the Continental’s parts are new - the body panels are carried over, while the front and rear are all new. This is one very effective mid-life facelift, with a heart transplant, then.

The S Class Coupe is obviously related to the sedan but manages a svelte appearance. Slimmer hipped and with a more Coke-bottle shape, the Coupe - if you squint a bit - has a bit of the classic old pagoda about it. Obviously you can't do pillars that slim anymore, but the glass roof takes away some of the visual weight inside and out. 

The cabriolet's roof is nicely integrated and looks good when it's  up, which isn't always the case.

They all look long, though. It's obvious to see why the cars all run on 20-inch wheels - anything smaller would look hilarious.

The cabin is a fairly sensible re-imagining of the E-Class. The big twin-screen layout of the dash and multimedia system seems a bit more at home here. The chintzy Burmester speakers in the doors let down an otherwise classy cabin, which steers clear of otiose vulgarity in looks and materials.

So a two-door, '2+2' grand tourer isn’t entirely built with the term 'practicality' in mind and it could be argued the existence of this Bentley Continental, the fourth generation, is something of a surprise, when you consider most people just buy SUVs and Bentley has done quite well with its Bentayga (which will, in future, share the same engine used here).

But for what it is, a two-seat car with occasional seating in the rear for emergencies, or very small children, it feels entirely fit for purpose.

An actual human can sit in the back, but it does feel a bit claustrophobic, and you’d be so jealous of how comfortable the people are in the front.

The 20-way adjustable front pews feel like grand armchairs for grand touring, fabulously comfortable - although you can slide across them a bit when driving on a race track, not a common problem - and plush to the touch.

They now come with a 'Wellness Facility' that brings postural, massage and climate functions to help with fatigue on long journeys - and epic blasts across multiple European countries is clearly what this thing is designed for.

In general, the cabin is just lovely, Bentley claims it does the best car interiors in the world and while Rolls might argue, it’s a pretty fair statement.

The spinning central 12.3-inch display remains the highlight, offering you a modern touchscreen, which can disappear to reveal either three classic analogue dials or a plain piece of dashboard, if you prefer a 'digital detox'.

Well look, if you end up in the back of the S Coupe, it's not a riot of space. Obviously it has back seats (the SL doesn't even squeeze a jump seat into its considerable length) but they're for occasional, if luxurious, use.

The boot is a reasonably decent 400 litres, obviously the cabriolet loses a few litres with the roof folded. Front and rear passengers will both enjoy a pair of cupholders and the whopping long doors will each hold a bottle.

One thing hasn't changed in nearly 20 years - the S isn't cheap. Available in coupe and cabriolet, the S560 starts at $314,900 for the former and $336,900 for the latter. Step up to the S63 pair and you'll pay from $370,500 for the coupe and $399,900 for the cab. If you're super keen for something spectacular, the twin-turbo V12-powered S65 is available for between $508,900 and $520,500, and features Swarovski crystals in the headlights, for some reason.

As you can imagine, there's quite a bit to cover, so for both cars I'll stick to the edited highlights. The S560s roll on 20-inch alloys, has a 590-watt 13 speaker sound system, digital TV, auto parking, active cruise control, panoramic glass roof, Nappa leather, active seats and power-closing doors.

It also comes standard with a heating pack that not only heats the seats but the steering wheel and centre console. In the cabriolet you also get the 'Airscarf' neck heater.

Both cars also feature's Mercedes' Magic Body Control with curve function. More of that wacky feature later.

The S63 AMG is a step up in power, price and spec. One notable change from the S560 is the loss of 'Magic Body Control', which is replaced with mere air suspension. The 20-inch alloys are 10-spoke forged units, the brakes higher performance composites with red calipers, while an AMG sports exhaust brings the noise.

Naturally, both are swathed in high-quality leather and feature dual-zone climate control, heated and cooled electric seats that adjust in every direction, deep carpets, keyless entry and start, fully digital dashboards and just about every gadget to which you can point your imagination.

Entertainment and sat nav are via Mercedes' 'Comand' system, which is displayed on a massive 12.3-inch slab of glass at the top of the dashboard. The 13-speaker Burmester-branded system is predictably impressive and with Apple CarPlay and Android Auto, you only have to use the basic software for the radio or various car controls.

There is some sadness that the world’s biggest producer and promoter of 12-cylinder engines has cut production of them altogether - the epic W12 is no more - and this does feel, on a smaller scale, like Porsche ditching flat-six engines forever.

Previous hybrid efforts from Bentley, including a V6-based one that the company now admits was a bit limp wristed, might cause some concern when you hear that Bentley will, henceforth, make just one engine for all its cars, and that it is a hybrid, albeit one attached to a 4.0-litre twin-turbo V8.

But then they point out the version in this Continental GT Speed’s is “the most powerful Bentley engine ever” and that sounds pretty good.

The engine alone makes 441kW and 800Nm, which almost sounds ample, but the addition of the electric E-motor is good for another 140kW and 450Nm, with the aid of a 29.5kWh battery, which somehow adds up to a combined output of 575kW and a nice, round, and impressive 1000Nm of torque.

All that power does have to move 2.5 tonnes of precious metal, which sounds like an ask, but is effortless in practice - hurling the Speed to 100km/h in a properly supercar-like 3.2 seconds on its way to a top speed of 335km/h.

Yes, vitally, it sounds pretty damn impressive when all the power sources are going at once, it even barks and pops on the overrun, a bit like the Porsche Panamera with which it shares the hybrid set-up, only a bit bossier, and perhaps classier.

The point of the hybrid feels like it’s mostly about performance and excitement, but it has a practical side, too, because in EV-only mode this giant Bentley can drive for up to 81km in pure, and slightly inappropriate-feeling, silence (at speeds of up to 140km/h).

Handy if you live in global cities with zero-emission zones, or if you want your neighbours to think you care about the climate.

One brilliant thing about this plug-in hybrid is it’s set up to use the engine to regen the battery, hard, in 'Sport' mode, so the more fun you have, the quicker the battery charges. So much so that, realistically, you might never need to plug it in at all (Bentley recently ran the car at a race track for two weeks and never needed to top it up via cable once).

It is an impressive, sonorous and enjoyable power plant, and you’d expect nothing less from Porsche, although Bentley says it’s done lots of work on the donor engine to make it uniquely more wonderful.

All four coupes and cabriolets ship with Daimler's formidable 4.0-litre twin-turbo V8. The S560 scores 345kW/700Nm to drive the rear wheels through Benz's own nine-speed automatic. With all of that available, the S560 will crack the ton in 4.6 seconds and make a wonderful racket on the way.

Moving on to the S63, the same engine delivers a massive 450kW/900Nm. The run from 0-100km/h is dispatched in just 3.5 seconds and if I thought the S560 made a good noise, the S63 with its standard sports exhaust makes a better one. Again, Mercedes' nine-speeder is along for the ride.

While the top-line figures for performance hybrids like this always sound impressive, it’s hard to believe anyone will ever get near them in the real world, because the temptation to drive a car like this hard and fast, as its makers clearly intended, will mean chewing fuel in a very non-efficient way indeed.

On paper, though, where it matters in terms of being allowed to sell your giant luxury grand tourer in Europe, the Bentley Continental GT Speed produces just 29 grams of CO2 per kilometre. 

Fuel economy is a claimed 10.3 litres per 100km, which is optimistic, but still a lot lower than the equally unlikely 14L/100km figure for the old (12-cylinders and no hybrid) car. As in, neither car would ever achieve the theoretical figure, but at least the new one is clearly a lot better.

The lower-powered 560 drinks 98RON at the rate of 8.5L/100km for the coupe and 9.9L/100km for the heavier cabriolet.

The S63 ups the ante with 9.9L/100km for the coupe and an identical 9.9L/100km for the cab.

Our launch program contained some...er...spirited driving, which would explain the mid to high-teens fuel figures.

In an ideal world, one would take the Bentley Continental GT Speed for an appropriate drive from the top of Germany to the bottom of Italy or France, but instead we were asked to drive the big beast around a tight and slightly terrifying private members race track outside Tokyo called the Magarigawa Club.

Members here pay US$1 million a year for access to this circuit, carved out of several mountain tops, which features two long and fun straights attached to what feels like a hill climb circuit with a bit of Laguna Seca’s Corkscrew and a touch of Mt Panorama’s undulations.

This track, with its daunting lack of run-off, should have been an intimidating and possibly inappropriate place to try the Continental GT Speed, but it is a credit to the car’s “everyday supercar” personality that it soaked up the pressure, and pace with ease.

On our first lap we were encouraged to drive in EV mode, which was predictably a bit dull, quiet and not-quite boring, because if you went past 75 per cent of throttle, or 140km/h, the engine would kick in and things would instantly get interesting.

It was a good chance to note just how lushly comfortable the cabin and seats are, however, and just how supple the suspension can be.

The Bentley’s “secret weapon”, according to its engineers, is a new twin-valve damper the allows the chassis to behave like a sports car when you want it to - probably about 3.0 per cent of the time for actual owners - and an absolute luxury pleasure palace for cruising around the rest of the time.

The split personality thing really is on offer with this car, as we found out once we engaged the Sport setting.

The Speed’s all-wheel drive, all-wheel steering, torque vectoring and electronic LSD were all on display over the later laps, in which we were allowed to blast past 200km/h and find out just how good the brakes are at pulling up 2.5 tonnes of high-speed luxo-barge.

You do your steering via a lovely wheel with a leather front and Alcantara wheel, and it feels effortless, even in full track attack mode. A bit more feedback might be nice, but I guess Bentley owners have other cars for that kind of thing.

Aside from the rushing, roaring speed, what is most impressive is how little body roll there is from the Continental. It feels planted, poised, happy to change direction and is rarely upset or flustered, despite some squeals of complaints from the tyres. 

Getting too wide on to the ripple strips caused a shudder and a skip sideways now and then, but perhaps I shouldn’t have been so far off the racing line.

Overall, the Continental GT delivers on its name, with Speed, and lots of it, all delivered in a properly swanky environment.

Let's start with the S560. That smooth V8 rumble is all you'll ever hear if you just slot into drive and go for a leisurely spin. The nine-speed automatic continues to be a revelation to me - in the GLC63 it's good and here, once again, it's excellent, finding the right gear for the occasion and riding the fat torque curve. Other nine-speed autos are not very good at all.

The test route for the S560 played to the strengths of the car. It had some lovely winding roads, which brought the trick suspension into focus - the Magic Body Control with curve function is hilarious. While the active suspension works hard at all times to ensure the ride is smooth and drama free, the Curve mode (no, really) actually leans the car into corners.

Those of you who remember the video game Wipeout 2097 will be big fans of Curve mode. As you approach a corner, you turn the wheel and then the car leans into the bend. This isn't active damping reading the road, it's the outside suspension lifting the car and the inside lowering it, so the car feels like it's gliding, like a hovercar. It's wild but oddly calming. Mercedes reckons it's great for those who get car sick. As I didn't have my wife on hand to test this theory - she chucks at the first sign of a corner - I couldn't verify this claim. That will have to wait.

The S63 AMG is a completely different proposition. The air suspension is more than up to the job of helping smother the effects of the car's considerable weight, meaning that no matter what you're up to, the car feels reasonably light on its feet. It never feels small, though, commanding the respect of the driver and plenty of space from other road users.

And boy, do you need some space if you kick the S63 into Sport mode. In true AMG style, the electronic reins relax and the big luxury coupe cheerfully kicks off. The tail will wriggle under an unsympathetic right foot, that signature V8 roar, crackle and hiss filling your ears. The S63 is always the harder-feeling car, but it delivers with a more sporting drive than the S560.

Being the generous soul I am, I volunteered to return the S63 to its home for the evening rather than consign it to the back of a truck. On the back roads I took to reach the highway, it was rock solid - fast, predictable and a lot of fun. Once I found the boring straight bits, it turned into a supremely comfortable cruiser, ticking along in ninth at the legal limit (and being Melbourne, it was very much the legal limit), dispatching overtaking with barely a flex of a toe. 

The active cruise took the stress of keeping away from the State Revenue Office's clutches while being quiet and utterly pleasant.

The S-Class coupe comes loaded with eight airbags, ABS, stability and traction controls, forward and reverse AEB with pedestrian detection, reversing camera, crosswind assist (I know, right?), traffic-sign recognition and reverse cross traffic alert.

The S-Class Coupe does not have an ANCAP or EuroNCAP rating.

The Bentley Continental GT Speed comes with a five-year, all-inclusive servicing plan as standard.

That sounds good, but stunningly, Bentley still only offers a three-year manufacturer warranty, albeit one with no mileage limitations. That's way below industry standard these days.

The battery that forms part of the hybrid system is, however, warrantied for eight years, or 160,000km.

Mercedes offers a three-year/unlimited-kilometre warranty with roadside assist for the duration.

The company also offers both service plans (where you pay up-front as part of the vehicle purchase) and capped-price servicing on the coupes. Servicing over three years is in the order $2500.
