Mercedes-Benz E53 vs Bentley Bentayga

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.

The Bentley Bentayga Azure may look a bit awkward and it surely isn't great value for money, but it is a true Bentley and a very good family SUV that not only provides terrific practicality but superb performance and comfort.

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. 

You'd think of all automotive brands Bentley, with its beautiful swooping and powerful saloons, would be able to floor us with something just exquisite in SUV form. But right from the 2012 concept the Bentayga has struggled to stun the world with its design.

So, while there are Bentley family traits all over the Bentayga, from the intricate headlights and mesh grille, to the oval tail-lights and body which squats over the rear wheels, the overall design looks awkward to my eyes.

To me it appears the boxy design with the tall, flat roofline and elevated ride height favours practicality over the sleekness possessed by a lower, more coupe-like SUV.

I favour dark coloured clothes because it hides my shapes, creases and bulges, but these are the things you want to see in a car and our Bentley's 'Onyx Black' paint, despite being a beautiful colour with a blue hue added, make it a featureless blob in the sunlight.

A lighter shade or something outlandish like a turquoise or yellow would look amazing, and even better, upset your neighbours.

Let's look at the interior design which is lavish with all the quilted leather and Mulliner customisation, but lacks the modern look of many contemporary cabins with its smallish media screen and busy mosaic of buttons.

I like the little chrome plungers for the air vents, the winged styling to the dashboard and the stitched leather upholstery, but it's easy to spot parts that are shared by other members of the Volkswagen Group (which owns Bentley).

For example, there are the indicator and wiper stalks, as well as the steering wheel buttons, all from Audi. Surely Bentley should have its own crafted parts?

The interior colour scheme on our Bentayga is 'Beluga' (black) and 'Camel' (tan) and the Mulliner option split the colours with a cream tone.

From a family perspective the tan and black will hide dirt, although the cream will struggle. It's possibly the best leather on the planet, however, coming from cattle living high enough that their hides are unblemished by insect stings.

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.

Being shaped like a bus does nothing for the Bentayga's beauty but makes it spacious for cargo and roomy for people.

With its large doors and elevated ride height (the car can be lowered for easier access) it's great for families.

Our Bentayga is a five-seater, which is fine for my little family of four, but there are four- and seven-seat configurations available, too.

Second row legroom is exceptional, even for me at 189cm tall, and sitting behind my own driving position there's still plenty of room.

Headroom is also outstanding throughout. We could be a family that loves top hats, on our way to the top hat championships, and not have to remove our top hats. That's how good headroom and hat room is.

Sun blinds in the second row are vital in Australia, and the electric ones in the Bentayga raise and lower quickly, not just offering protection but also more privacy.

Storage is good throughout with big door pockets and five cupholders.

It seems the cabin space eats into the cargo area because the boot isn't overly large at 484 litres with all seats in place.

Buttons in the cargo area allow the rear of the car to be raised and lowered to make it easier to hoist items in the boot.

For devices there's a wireless phone charger up front along with USB ports in both rows.

Reviewing every type of car on the market provides a pretty good perspective, but when it comes to Bentleys we enter a realm where value-for-money often isn't as crucial as it is for more mainstream options.

The same goes for the price. Bentleys are among the most expensive cars in the world. So if, like me, you flinch at the thought of paying more than half a million dollars for an SUV, it may not be the car for us right now.

With that I can tell you the Bentley Bentayga Azure's list price is $475,000 and our car with all of its options comes to $515,000.

That's more money than any SUV from Mercedes-Benz and BMW costs. Even Range Rover can't quite reach that mark.

Only the likes of Aston Martin's DBX 707 and Lamborghini's Urus can match the price.

There are always bigger fish, though, and Rolls Royce's Cullinan swims in at $700,000, making the Bentayga's price seem quite reasonable.

Let's look at the standard features.

Coming standard on the Bentayga Azure are the prettiest LED headlights in the world. There are LED tail-lights, too, as well as a proximity key, roof rails and a panoramic glass roof, plus a hands-free tailgate.

Inside there's the 10.9-inch media screen, sat nav, wireless Apple CarPlay and wireless Android Auto.

The diamond quilting to the door trims is also standard and so are the Bentley sports pedals.

Many of these features are standard on lower grades in the Bentayga range, but the point in choosing the Azure is that many of the optional bundles on offer are fitted as standard here.

So, while leather upholstery is of course standard the 'Colour Specification' package gives you a choice of all interior colour combinations and an extended choice of hide colours.

The 'City Specification' brings extra safety tech like rear cross-traffic alert and a top view camera.

The 'Front Seat Comfort' specification adds 20-way power front seats, ventilation and massage as well as comfort headrests.

The 'Touring Specification' brings adaptive cruise control, a head up display, lane keeping assistance and 'Night Vision'.

And then the 'Sunshine Package' adds electric sun blinds, which are great for kids in the back.

Despite the multitude of standard packages there's plenty left to option on the Azure.

Our car was fitted with about a dozen options including piano black veneer ($5884), 22-inch alloy wheels ($4733), rear privacy glass ($2617), LED welcome lights ($2238), self-levelling wheel centre caps ($1208), a heated acoustic windscreen ($1094), luggage management for the boot ($937) and a heated steering wheel ($543).

Then there's Mulliner, Bentley's in-house customisation division which will personalise your Bentley.

The Mulliner custom features on our Bentayga Azure include the addition of an extra colour in the leather upholstery ($13,492), 'Honeycomb' stitching on the steering wheel ($5391) and contrasting stitching on the quilted areas of leather trim ($2688).

Best family features would have to be the privacy glass, temperature control in the second row and the rear sun blinds.

The second row also comes with a removable tablet which can be used to adjust the climate control, sunroof and media settings among other functions.

In the hands of children this is every parent's nightmare and there's a 100 percent chance of the tablet being lost forever, possibly on the motorway between Sydney and Canberra.

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.

When Bentley stopped putting its W12 into the Bentayga this year I was unsurprised yet sad. The world is moving toward tighter fuel emissions but the twin-turbo petrol V8 in this Azure is still a beast.

The 4.0-litre turbo-petrol V8 is from the Audi family and I love it as much for its plentiful torque and superb acceleration as the deep rumble of its exhaust.

Making 404kW and 770Nm the V8 can lift and throw the 2.5-tonne Bentayga to 100km/h from a standstill in 4.5 seconds and onto a top speed of 290km/h. I reckon you could get it to 300km/h with the wind behind you.

Drive goes to all four wheels via an eight-speed transmission and a Torsen-type centre differential.

Default drive balance is 40/60 front to rear, with up to 70 per cent of power able to be sent to the front wheels and up to 85 per cent to the rear axle.

I don't think you'll be astounded to hear this powertrain uses a lot of fuel? Let's go there...

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.

Bentley says the Bentayga Azure with the V8 petrol engine will use an average of 11.4L/100km over a combination of open and urban roads.

But what happens if you live in the suburbs not far from the city and drive the Azure every day to do the school drop offs and trips to the shops and then take in some fun country roads? You use an average of 22.8L/100km according to the car's trip computer.

This is still not as high as I was expecting. I've driven V6-powered SUVs which use more than this under the same conditions.

That said, even when using as much fuel as Bentley says you should, an 85-litre fuel tank is only going to deliver an approximate 745km driving range.

The Bentley Bentayga doesn't have a safety rating as like many extremely high-end cars it hasn't been assessed by ANCAP or Euro NCAP.

That said, the Azure grade comes standard with an armoury of safety tech including AEB (with turn assistance), lane keeping assistance, blind-spot warning, rear cross-traffic alert, evasive steering assistance, and adaptive cruise control.

Front and rear parking sensors are standard (and the most relied-upon feature I use daily), while exit warning saved my child and myself more than a few times from leaping out into the traffic on the school run.

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 Bentayga is covered by Bentley's three-year/unlimited-kilometre warranty. Servicing is recommended every 12 months or 16,000km.

The good news is all new Bentley's have five years regular servicing included in the cost of the vehicle.
