Bentley Bentayga vs Lexus IS200T

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 Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.

When you buy a Lexus, they don't like to let go of you. My father-in-law's original IS 200 is still fetched by the dealership - should he so desire - for its annual service. If he chooses to darken the dealership door himself, he'll drive out in a loan car. Nobody has ever stalked him at the dealership demanding he consider a new one.

The IS200t seems the pick of the IS bunch, despite pricing on par with a couple of the IS350s. It's a worthy alternative to the usual suspects, with its own look, feel and approach to luxury motoring. In fact, it's far more a luxury car than sports sedan, but manages to do both well. In the end, a BMW will edge it for handling and overall chassis grace, the Merc has that badge and the Audi is all-wheel drive and bang-up-to-date.

But none of them can touch the Lexus for after-sales service nor are any of them quite as well put together as the Japanese-built IS. It may not be as fast or as fun, but it's very, very good.

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.

The current IS is by far the most distinctive of the three generations. With a couple of exceptions, it is a terrific looking car. It looks long and low slung, like the best sporting sedans, with an almost Maserati-like approach to its proportions. The loud and proud Lexus spindle grille - the object of such derision when it first arrived - looks utterly fantastic and draws attention away from the odd, squished headlights.

it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers.

Inside is less impressive, with a weird stacked dash and integrated screen. The materials are top notch, however and while the designers have tried to do something interesting with the dash design, there are better ideas out there they might want to consider next time around.

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.

The IS's cabin is probably the weakest point of the car, with limited storage for your bits and bobs. Front and rear seat passengers do get cupholders for a total of four, but the rear doors don't have bottle holders, limiting you to the two upfront.

On hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

The centre console bin is small and is the only place for your phone apart from the cupholders, which isn't an ideal spot, let's face it. The boot is a German-matching 480 litres and you can split fold the seats for more room.

Having said that, it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers. The front seats are especially good and on hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

The IS range kicks off with the 200t Luxury at $59,340, closely followed by the hybrid 300h, the V6-powered 350 ($65,390) and then the $73,540 200t F Sport. Pricing then heads up into the mid-$80,000s for the IS350 Sports Luxury.

The 200t F Sport's almost $74,000 price tag fetches you a car with 18-inch alloys, dual-zone climate control, reversing camera, front and rear parking sensors, a hefty safety package, electronic dampers, auto LED headlights, auto wipers, electric heated and cooled front seats, digital instruments, sat nav, keyless entry and start, leather (some real, some not) interior, variable ratio steering rack and power everything.

The 10-speaker stereo is Mark Levinson branded and is controlled by Lexus' own connectivity and sat nav suite. The sound is fantastic, the control system less so. Commands come from a few shortcut buttons (good) and weird mouse-type arrangement on the centre console that is largely infuriating. The less said about the on-screen graphics, the better - they're low-res and on occasions, amateurish. You can connect via USB or Bluetooth but the app integration is limited. You also get an at-first unfathomable DAB+ radio.

Once on boost, the engine is smooth with a lovely flat torque curve.

Options are limited to $1500 for premium paint, which makes up eight out of ten colours.

Out of interest, $74,000 gets you a reasonably well equipped BMW 330i M Sport or Luxury Line and a few hundred dollars more will get you into a hybrid 330e M Sport. Audi will cheerfully sell you a loaded-up A4 quattro 2.0 TFSI and Mercedes might be tempted to sell you a C350e. Infiniti will probably throw themselves at you with a V6 twin-turbo Q50 Red Sport rocketship, or at the very least a V6 Hybrid Premium.

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 200t denotes a 2.0-litre turbocharged four-cylinder under that long bonnet, delivering 180kW and 350Nm to the rear wheels via an eight-speed automatic transmission. This translates to seven seconds dead to 100km/h for the 1680kg sedan, which isn't hanging around.

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.

Try as we might - and we did - we couldn't get at all close to the claimed combined fuel figure of 7.5L/100km. We didn't even hit the standard plus 30%, but we did get 12.2L/100km. That's a fairly solid miss.

Standard safety kit includes eight airbags (including knee bags for front seat occupants), ABS, stability and traction controls, blind spot sensor, lane departure warning, rear cross traffic alert, brake assist and driver attention detection.

The IS scored the maximum available five ANCAP stars when it was re-tested in October 2016.

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 Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.
