Bentley Bentayga vs Mercedes-Benz X220

What's the difference?

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.

The X-Class Pure 4x2 is good, but that's its major problem, because three-pointed stars and their high price tags bring with them a justified expectation of being not just good - but great. If a second-generation X-Class needs to borrow some components again, we hope they're from the legendary G-Wagen next time. In fact,a platform share between X-Class and G-Wagen (like Ranger/Everest or Colorado/Trailblazer etc) would have much greater appeal.

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.

Benz has re-engineered the Navara's steel ladder-frame chassis for greater rigidity and topped it with a restyled body that's 85mm longer and 126mm wider with a new M-B interior. There are also new front suspension components and a new coil-spring multi-link live rear axle assembly with disc brakes, which result in track width increases of 82mm front and 75mm rear (compared to RX Navara 4x2).

These engineering changes, combined with revised springs, shocks, anti-sway bars and steering, result in sure-footed handling with sharp steering response, excellent ride quality and a feeling of solidity that are all X-Class strengths. However, they have also resulted in a hefty 236kg weight gain.

The X-Class Pure 4x2 rides on a 3150mm wheelbase with a 5340mm overall length, 1916mm width and 1839mm height. In comparison to Ford's Ranger, which is considered the 'bigfoot' of Aussie dual cabs, the X-Class is 70mm shorter in wheelbase and 22mm shorter overall, but 56mm wider, 24mm taller and lineball on turning circle at 12.8 metres. So, like the Ranger it's quite a large and imposing vehicle.

Critical rough road credentials include 222mm of ground clearance with 30 degree approach and 25 degree departure angles. Its wading depth of 600mm is better than Amarok (500mm) but considerably less than Ranger (800mm).

It's nice to see sizeable grab handles on the window pillars for front and rear passengers and the driving position is pretty good. However, the Pure's front seats lack sufficient lumbar support and the base cushion (at least the driver's) needs some rake adjustment, as it can feel like you're sliding off the front at times.

For such a sizable vehicle we're surprised by how cramped the rear seating is for taller adults in terms of length and height, with knees touching the front seat backrests and, thanks to the higher 'grandstand' style rear seating, heads touching the roof lining. The rearward location of the B pillar also makes for quite tight entry and exit for those long of limb and large of shoe.

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.

Deducting the 4x2 Pure's 2046kg kerb weight from its 3200kg GVM would normally equal a payload of 1154kg, but the official payload figure is 68kg under that at 1086kg, which is an extra safety margin should the payload (but not the GVM) be exceeded.

The Pure 4x2's braked towing capacity of up to 3200kg is less than the 4x4 models' 3500kg rating. Even so, its generous 6139kg GCM allows for a substantial 884kg payload while towing its heaviest trailer load, which is impressive.

The load tub is 1581mm long, 1560mm wide and 475mm deep, with 1215mm between the wheel arches ensuring it can carry an 1160mm-square standard Aussie pallet. As mentioned earlier, our test vehicle was equipped with the optional $490 rear window guard frame, which should not only be standard but also have tradie-friendly pivoting load retainers or 'book-ends' on each side for carrying long lengths of timber, PVC pipe, etc.

The test vehicle's adjustable load-securing rail system mounted near the top of the tub (as seen on Navara) works well for securing loads of matching height or more, but there also needs to be four tie-down points in each corner at floor level to secure lower loads as well. The absence of load retainers and floor level tie-down points are glaring omissions for such a work-focused vehicle.

With tradies in mind there's also a lack of cabin storage, limited to bottle holders and storage pockets in each front door, an overhead sunglasses holder and small glove box. The multimedia system's sizeable rotary controller and touch-pad occupy a big chunk of potential storage space in the centre console, which only offers a tiny front storage slot, single cup holder and small rear lidded box (and there's no box if you opt for the 1-DIN audio ports as fitted to our test vehicle).

Rear seat passengers get a bottle holder and smaller storage pocket in each door and the bench seat base pivots upwards to a vertical position if you want some extra internal cargo space. But there are no flexible storage pockets on the front seat backrests and no cupholders. This needs a re-think because you quickly run out of places to store things.

Our test vehicle is as basic as an X-Class can get - the X220d Pure 4x2 dual-cab with six-speed manual transmission for $46,400. It's effectively a 'Hi-Rider' in industry speak, even if M-B doesn't use that term.

Given its work-focused specification, with hose-out vinyl floor, 17-inch steel wheels with 255/65 R17 road-biased tyres and matching spare, plus black bumpers, door handles, hub caps, etc, with not a hint of bling anywhere (bar the shiny three-pointed star on the grille), pricing north of $46K (before on-road costs) is Pikes Peak steep compared to the competition.

For example, the Ford Ranger Hi-Rider 4x2 in base-level XL trim with 2.2-litre diesel and six-speed manual is only $36,390 and Toyota's HiLux Workmate 4x2 Hi-Rider with 2.4-litre diesel and six-speed auto is $39,490.

And keep in mind our test vehicle also has the $1300 'Plus Package' ('Parktronic' and adjustable load-securing rail system), optional 1-DIN audio access ports ($150) and rear window guard frame ($490), raising the price to $48,340. That's a lot of money for a new player to be asking at base level, regardless of how much its star may twinkle.

Even so, the X220d's standard equipment list does include useful stuff like front fog lamps, DRL and dusk-sensing head lights, cruise control, tyre pressure monitoring, rear view camera, four 12-volt sockets, load tub light, four-speaker audio system with big 7.0-inch screen, multiple connectivity including Bluetooth and steering wheel controls, plus benchmark safety.

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 X-Class shares the Navara's engines and transmissions, but Nissan's superb YS23DDTT 2.3 diesel with sequential twin turbocharging and 140kW/450Nm is reserved only for the X250d variants.

The entry-level X220d Pure 4x2 and 4x4 models (like the entry-level Navara RX) make do with the less powerful but still excellent single turbo version with variable vane technology, producing 120kW at 3750rpm and 403Nm of torque between 1500-2500rpm.

The RWD Pure's six-speed manual gearbox (backed by hill start assist) has a pretty low (4.685:1) first gear which is handy for getting big loads underway from standing starts, while the over-driven top gear allows economic engine rpm at highway speeds. There's no rear diff lock like the Ranger Hi-Rider.

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.

Mercedes Benz's official combined figure is 7.6L/100km and the instrument display was showing that figure at the end of our test, which covered more than 660km on different roads (sealed and unsealed) and with a variety of loads, including our usual GVM run.

By comparison, our figures calculated from trip meter and fuel bowser readings came in at 9.0L/100km. Any dual-cab ute, particularly one this size, which can deliver genuine single-digit fuel economy in 'real world' driving gets a big tick from us. Based on our figures, you could expect a realistic driving range of 850km-plus from its 80-litre tank, which is fuel efficiency with a capital E.

Maximum five-star ANCAP rating and first dual-cab ute to bring AEB to this segment gets a rare perfect score from us. Passive safety includes driver and front passenger front, thorax, side curtain and driver's knee airbags, child restraint top tethers plus iSize and ISOFIX anchorages on outer rear seat positions.

Active safety also includes lane-keeping assist and vital ute features like brake-force distribution, trailer stability assist, hill start assist and tyre pressure monitoring.

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.

Warranty cover is three years/unlimited km with 24/7 roadside assist.

Service intervals are 12 months/20,000km, whichever occurs first. Under M-B's 'Service Care Promise' the first three scheduled services will cost between $585 and $930.
