Mercedes-Benz E53 vs Bentley Continental

What's the difference?

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

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.

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

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.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

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'.

As always, value becomes a nebulous term once the price of a car surges into the multiple hundreds of thousands. The Bentley Continental GT Speed will set Australian buyers back a whopping $581,900, before on-road costs.

Yes, you really can buy Ferraris and Lamborghinis for that kind of money, but Bentley assures us its buyers have already owned such fearsome machines, grown tired of their compromises and want something that’s just as fast, but 1000 times more comfortable, and easier to drive every day, and everywhere.

So that’s where the value proposition sits, basically. You’re buying a supercar that’s also a kind of Rolls-Royce adjacent luxury cruiser. Two cars for one price. Bargain. Kind of. It also weight 2.5 tonnes, if you’d like to think of it in dollars per kilogram.

Oh, and it’s hand made, too, and genuinely feels like it.

For that money you get an incredibly posh and plush cabin, excellent seats, and everything you touch, and smell, seems expensive and refined.

The newly facelifted, and butt-lifted, Continental also looks simply stunning, from every angle, outside. Particularly in its new 'Tourmaline Green' paint (there are 18 standard colours to choose from, or you can have bespoke paint made for you on request). And 15 standard leather hide colours as well.

It comes with all the apps and connectivity you could wish for, including a Bentley App Studio.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

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.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

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.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

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.

All the money and you only get four airbags; front and side for driver and passenger. And none in the back, so don't sit there. Bentley also has its own 'Safeguard' suite of technologies including 'Advanced Emergency Braking', 'Swerve Assist' and 'Turn Assist'. 

Other tech includes 'Predictive Adaptive Cruise Assist with Lane Guidance', 'Lane Departure Warning', 'Emergency Assist', 'Remote Park Assist' and '3D Surround View'.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.

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.
