Bentley Bentayga vs Mahindra XUV500

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.

This petrol-powered and well-priced XUV500 W6 might mark Mahindra's most convincing effort at cracking Australia's congested SUV market, but we're still not completely convinced.

That said, it's certainly cheap, the ownership credentials stack up and it's a very comfortable way to transport seven people.

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.

There's no getting away from the fact the XUV500 is not the sleekest, prettiest SUV in the pack. But it's not ugly, either. More that it looks like it's doing its best with a design philosophy hatched a generation or two ago.

Its best angle by far is when viewed straight on, where the piano-black grille, dual bonnet bulges and complicated (read: a little weird) headlight clusters all add some road presence to Mahindra's only SUV.

A side-on viewing, however, is less satisfying, where a combination of strangely placed and super-sharp body creases (including one over the rear wheelarch, which adds a Harbour Bridge-style crescent to the otherwise-straight window line) and serious rear overhang give the XUV500 an inescapable awkwardness.

Inside, expect a vast collection of rock-hard (though nicely patterned) plastics, with the ambiance rescued somewhat by the clean-looking and vertical central control unit, which is home to the media screen and air-con controls. 

Ready for some hashtag real talk? There are better-looking and better-feeling seven-seat SUVs out there. But there aren't many that start at $25,990 drive-away. And I think that's Mahindra's point.

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.

Pretty damn practical, actually, regardless of whether you want to carry people or cargo. Carrying both at the same time, however, is tricky.

But let's start with people. There is a huge amount of room in the third row of the XUV500, a space with enough head and legroom to put plenty of its competition to shame.

Thanks to second-row seat backs that fold flat, before the the entire seat lifts up and pushes forward, climbing into seats six and seven isn't too big a drama, either. 

We rarely say this about seven-seat cars, but at 175cm, I'd feel plenty comfortable back there on a longer drive. There are two air vents in the third row, too, along with bottle storage and side-seat storage for thin items.

All XUV500's are fitted with a 70-litre fuel tank. 

The space in the middle row is ample as well, and you'll find three ISOFIX attachment points, one for each of the three seats. There's also a door pocket in each rear door and storage nets on the rear of the two front seats. A pull-down divider that separates the back seat is home to two cupholders, matching the two for front seat riders. 

The only downside to all this people-lugging happiness is that, with the third row of seats in place, there is absolutely no room for luggage. Mahindra doesn't quote a litre storage figure when seven are seated (mostly because it would probably be embarrassing to write "one litre"), but trust us, you'll be lucky to squeeze a soft backpack in the boot with all seats in place.

Things improve considerably when you drop the third row of seats, though, which unlocks 702 litres of storage, and that number climbs to 1512 litres with the second and third row folded down.

Make no mistake, this Mahindra kills the competition on price. The entry-level W6 version will cost you a lean $25,990, while the fruited-up W8 version will set you back $29,990. You can even have an AWD W8 for $32,990. The best part? All of those are drive-away prices.

Go for the W6, and you can expect 17-inch alloy wheels, cloth seats, air-con with vents (powered by a second compressor) in the second and third row, cornering headlights with DRLs, front and rear fog lights, cruise control, rear parking sensors and a 6.0-inch multimedia screen linked with a six-speaker stereo.

Spring for the W8, and you'll add leather seats, a reversing camera, tyre-pressure monitoring and a bigger, 7.0-inch screen with standard sat-nav.

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...

There's a diesel engine currently available, but the clock is ticking - Mahindra expects it to be phased out within six months. But the big news here is the new petrol engine, a turbocharged 2.2-litre unit good for 103kW/320Nm. It's paired exclusively with an Aisin-developed six-speed automatic transmission, and will send it's power to the front or all four wheels.

Mahindra doesn't quote official performance figures, but those engine outputs hardly scream excitement, do they?

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.

Local numbers are yet to be confirmed, but after an admittedly vigorous local test, the on-board computers was reading 13+ litres per 100km. All XUV500's are fitted with a 70-litre fuel tank.  

Expect dual front, front-side and curtain airbags (though the latter don't extend to the third row of seats), along with rear parking sensors and ESP. Stepping up to the W8 trim adds a reversing camera with dynamic guidelines. The XUV500 was awarded a four-star (out of five) ANCAP assessment when tested in 2012.

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.

All XUV500s are covered by a five year/100,000km warranty (though the final two years apply only to the drivetrain), along with five years of complimentary roadside assistance.

The XUV500 is also covered by Mahindra's capped-price servicing program for the first three years of ownership, and will require servicing every six months or 10,000km.
