Bentley Bentayga vs Holden Spark

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 marvels of local engineering strike again: the Spark LT definitely feels a cut above some of its budget competition from behind the wheel. It is well-equipped, too, and packed with connectivity and technology features. In short, it could be just the spark Australia's city-car segment needs.

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 only so much that can be done with a car in this bracket (there's hardly an abundance of surface metal to play with), but Holden's Korean design team have done an admirable job of inserting some excitement into what is traditionally a fairly bland category.

More youth appeal arrives courtesy of a huge array of personalisation options.

A powerful front end, with two fog lights sitting below the headlights, is dominated by a vaguely Kia-esque grille. And when viewed side on, the Spark looks to be sitting low, courtesy of standard 15-inch alloys that fill the wheel arches and tarmac-kissing side skirting that runs front to back. Two fairly heavy body creases also break up the metal monotony, running along the front and rear doors.

It's an energetic-looking package, and even more youth appeal arrives courtesy of a huge array of personalisation options, with Holden promising 33 different changes a buyer can make, including the wheel inserts, wing mirror caps and roof rails.

Inside, the focus is more on connectivity than luxury, so you can expect fake leather, hard plastics and fairly ordinary seat cushioning, but it's all nicely put together, and the basic feel is broken up by some well-placed style elements, like the coloured insert that runs the length of the dash.

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.

Nope. This is a pocket-sized car, namely because it has the same cargo capacity as your pocket.

Holden has stretched the space between the wheels to maximise passenger space, and as a result there's actually plenty of room in either row. But to add space somewhere, you need to take it from somewhere else, and that somewhere else is the boot, where you'll find a mere 185-litres of luggage space. The situation is improved by dropping the 60:40 split rear seats, but you'll be forever choosing between passengers and luggage.

Front seat passengers share a pair of cupholders, but rear seat passengers get none. They don't get room for bottles in their door pockets. Or door pockets at all, for that matter. The backseat does, however, get two ISOFIX attachment points, one in each window seat.

While the cheap and cheerful entry-level Spark, the $13,990 LS, plays smack-bang in the middle of the micro-car segment, the top-spec LT has bigger, and considerably more expensive, shoes to fill. At $18,990, the LT sails perilously close to its bigger and equally well-equipped competition.

For that money, the Spark needs to arrive wanting for little, and in most respects it does exactly that. For a start, a CVT automatic is standard, and is joined by some stand-out features in this segment, like cruise control, keyless entry with proximity unlocking, push-button start and a fake leather trim that Holden calls Sportec.

While navigation isn't standard, the Spark LT's seven-inch touchscreen is both Android Auto and Apple Car Play equipped, so phone maps fill the blank with ease.

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 just the one engine available across the Spark range, and that's a 1.4-litre petrol unit that'll generate 73kW and 128Nm.

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.

Spring for the LT, and that's paired with a CVT automatic transmission, with Holden promising that combination will sip a claimed/combined 5.5L/100km (though we recorded a less impressive 8.0 litres on our test).

Standard safety fare comes courtesy of six airbags, along with hill-hold assist, ABS and ESC, but it does miss out on more advanced technologies like autonomous brakes.

Springing for the LT will add rear parking sensors, a rear-view camera and cruise control as standard fare, though the lot can be added to the entry-level LS as part of Holden's Driver Assistance Pack.

The Spark range scored the maximum five-star ANCAP safety rating when tested early this year.

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.

The Spark range is covered by a three-year, 100,000km warranty and requires servicing every 15,000kms. The Spark range falls under Holden's lifetime capped price servicing scheme, with trips to the dealership capped at $1,145 total for the first five services.
