Bentley Continental vs Audi RS5

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.

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

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.

I defy anyone to describe the RS5, and especially the Coupe, as anything but stunning. Seriously, the near perfect proportions and swept-back styling make it look fast even when it's parked. 

Up front, there's a new-look black-mesh grille that's been given a 3D effect, like it juts out over the road in front it, while the thing headlights have been carved back into the body work like they're been windswept under hard acceleration.

The 20-inch darkened alloys fill the arches, too, with a sharp body crease that runs from the front headlight all the way back to the bulging shoulder lines above the rear tyres accentuating the curves.

Inside, the RS5 is a sea of black Nappa leather and sporty touches, and we particularly like the chunky, flat-bottomed steering wheel, which both looks - and feels - great.

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'.

We only tested the Coupe, and I can tell you that the practicality perks on offer largely depend on where you're sitting.

Up front, you're spoiled for room in the two-door Coupe, with the two spacious seats separated by a sizeable centre console that's also home to two cupholders and a variety of cubbies, with extra bottle storage in each of the front doors. 

The back seat, though, is a little, or a lot, tighter, with come acrobatics required to even climb into it, given the Coupe only has two doors. The Sportback offers two more doors, which will surely make the process a little easier. 

The Coupe measures 4723mm in length, 1866mm in width and 1372mm in height, and will deliver a decent 410 litres in luggage space in the boot. The Sportback measures in at 4783mm, 1866mm and 1399mm, and boosts your luggage space to 465 litres.

Either vehicle has your tech needs sorted, with an abundance of USB and power outlets serving both front and backseat riders.

It's available as a Coupe or a Sportback, but either way, the RS5 commands a $150,900 asking price. And that's not chump change, but Audi's performance model does come with a lot of bang for those bucks.

We'll get to the engine and safety stuff in a moment, but in terms of fruit, you'll find 20-inch alloys outside, as well sportier RS body styling, sport brakes, Matrix LED headlights, keyless entry and push-button start and heated mirrors, a sunroof and privacy glass. Inside, there's Nappa leather seats (heated in the front), illuminated door sills, stainless steel pedals and ambient interior lighting.

The tech stuff is handled by a new 10.1-inch central touchscreen that gets both Apple CarPlay and Android Auto, as well as Audi's Virtual Cockpit, which replaces the dials in the driver's binnacle with a digital screen. There's also wireless phone charging, and a killer 19-speaker Bang and Olufsen sound system.

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.

Its a terrific engine, this - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 3.9 seconds in the Coupe and the Sportback. Which is very, very quick.

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 RS5 Coupe will sip a claimed 9.4L/100km on the combined cycle, and emit a claimed 208g/km of Co2. It's fitted with a 58-litre fuel tank. 

The RS5 Coupe will the same 9.4L/100km, but emit 209g/km of Co2.

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.

With our time behind the wheel limited to the RS5 Coupe, we can only really report on how the two-door feels on the road, but given the prodigious power on offer, it's unlikely the addition of two doors is going to make the Sportback any slower. 

In short, the RS5 is thunderously fast, collecting speed with utter nonchalance thanks to this thick and endless-feeling supply of power unleashed whenever you plant your right foot.

It makes even the most ham-fisted attempts at cornering feel fast as lightning, with the power flow able to make up for every slow entry and exit by simply piling on pace between bends. 

But that's what you expect from an RS model, right? So perhaps more impressive is the RS5's ability to transform back into a relatively sedate urban cruiser when the red mist subsides. The suspension is firm, especially over rough road surfaces, and you do need to be a little careful with the accelerator to avoid that lurching feeling at every green light, but driven calmly, it doubles as a everyday car quite nicely.

Like in the RS4, we did find the gearbox felt a little quick to change at pace, shifting up or down at strange moments on the way into or out of corners, but you can reclaim control via the paddle shifters.

The safety story begins with six (Coupe) or eight (Sportback), and the usual suite of braking and traction aids, but then climbs into the tech-savvy stuff from there.

You get a 360-degree camera, adaptive cruise with stop and go, active lane assist, front and rear parking sensors, AEB with pedestrian detection, rear cross-traffic alert, an exit warning system, blind-spot monitoring and turn assist, which monitors oncoming traffic when making a turn.

It's a lot of gear, and it all contributes to Audi's five-star ANCAP safety rating, awarded in 2017 to the A5 range.

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.

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.
