Lexus RX200T vs Lexus RX450H

What's the difference?

Big, practical and comfortable, the Lexus RX 200T F-Sport deserves its place in the premium SUV pantheon. And don't let the little engine fool you, the turbocharged four-cylinder unit serves up plenty of poke to get the RX moving. But if it's fancy new technology that really excites you, prepare for mild disappointment, with the RX's in-cabin tech feeling a little underwhelming.

The RX is a little frustrating - it's going after Mercedes and BMW and Audi in a hotly-contested space and falls over in a couple of key areas. The media/sat nav system is hopelessly outdated and the drivetrain fails to deliver a significant performance or fuel benefit (although, given its 2.2 tonnes, perhaps it delivers a miracle).

It does come with a rock-solid, scandal-free reputation, a reputation for spectacular customer service, it has a lovely cabin and it's certainly an individual looker. For plenty of people, that's quite enough.

Angry, aggressive and very un-Lexus, with a jaw that looks like Ivan Drago somehow transformed into an SUV - that pretty much sums up the RX. 

Lexus is already on record as saying its designers had mistakenly tried to make their cars appeal to everyone in the past, and so they ended up boring and tame as a result.

Now they're happy if one person in 10 really loves them. Exactly where you sit on that scale is up to you.

Up front, that 'Spindle Grille' (shaped a little like the Predator’s mouth) serves up plenty of road presence, while the sharply angled fog-light housings and deeply domed bonnet give it a more powerful stance than perhaps is justified by its 2.0-litre engine.

Side on, the big and shining alloys, deep curve above the base of the doors and flared, squared-off wheel guards add plenty of personality to what could have (and in the past, would have) otherwise been a long and featureless stretch of metal.

Step inside and the cabin is premium-feeling, if a little busy, with the doors and dash covered in a combination of soft-touch materials and padded leather. The brushed aluminium-look central tunnel that separates the front seats is super wide, as it houses the  the cupholders, drive-mode selector and the strange mousepad that controls the entertainment system, but feels nice under the touch and becomes a kind of focal point in the cabin.

There's a lot of RX and there's a lot going on in that creased, folded and teased sheetmetal. It's a unique design, with a huge 'spindle grille', big lights and the fast glass both front and rear.

It positively screeches Lexus DNA and was a polarising force on our driveway for the week. Most weren't sure, but knew for certain it was a Lexus.

Aggressively flared wheelarches like this aren't common on SUVs (although the squared-off ones are). It's right up on stilts, but the 20s you find it rolling on help to reduce its visual bulk.

That wacky rear quarter glass reminds me of the BMW i3's but it's a Lexus SUV signature. It's quite striking. Do I like it? Not really, but that's completely subjective. You can tell, though, it's built tight as a drum.

Inside is a bit calmer, beautifully laid-out and built to last. The materials are almost all top notch, with lovely switchgear and the real leather is really nice.

There is absolutely nothing avant-garde in there (apart from maybe the pinstripe effect on the centre console), it's all terribly comfortable and easy on the eye. But not exciting, though not all Lexuses are.

This particular car is very US-centric and, if I may, a particularly sunny and humid part, so it can't be too wacky.

Australia’s laser focus on small and city-sized SUVs has been so intense that’s it’s easy to forget the joys of our bigger cars. Stretch out in the 4890mm long and 1895mm wide Lexus NX and it all comes flooding back. 

There’s plenty of space for up-front riders (even with the football pitch-sized centre console), as well as two cupholders and extendable pockets in each of the front doors. The cubby that splits the front seats is ridiculously deep, too, and is home to two USB connections, a power outlet and and aux-in point.

Step into the back seat and you’re greeted by plenty of space in each of the window seats, although the central stack that houses the air vents and another power outlet does jut out into the legroom of the middle-seat passenger. There are two bonus cupholders hidden in a pulldown divider that drops from the middle seat, and two ISOFIX attachment points, one in each window seat in the back.

Rear seats in place, the RX serves up 453 litres of luggage space, although you can stretch that to 924 litres by folding the backseats flat.

There is plenty of room inside this big unit, which is very welcome. Front seat passengers have lots of storage, such as a deep central bin under the armrest, dual cupholders and big door pockets with bottle holders.

Step into the rear and there is a ton of leg and headroom although the transmission tunnel intrudes slightly for the middle passenger. Chuck them out, drop the armrest and you have two more cupholders and each door has pockets and bottle holders.

The boot is pretty big considering the angle of the rear glass. You start with 453 litres (but an expanse of flat floor), which rises to 924 litres with the split-fold seats down. That seems conservative given just how much space you appear to have.

The RX450h F Sport lightens your bank account of $102,460 before on-road costs, the only hybrid SUV within cooee of this price.

That nets you 20-inch alloys, a 15-speaker stereo, dual-zone climate control, heated and cooled electric front seats, reversing camera, that ever rare CD player, keyless entry and start, a solid safety package, reversing sensors, active cruise control, sat nav, a massive sunroof, auto LED headlights, head-up display, partial leather interior, power tailgate, auto wipers and a space-saver spare.

The Lexus media system is run from the gigantic dash-mounted screen that is shamed only by those massive Tesla units.

Sadly, the joystick-style control remains as does the very confusing software system that is less than delightful to use. It's such a shame that a tech-laden machine is let down by the world's most baffling entertainment system.

Once you get it working and understand it, it's okay, I guess, but several years into this job I still can't easily fathom how it works. And that naff analogue clock...

F Sport cars also pick up adaptive suspension and a several driving modes to liven things up.

There was a time not so long ago when the thought of fitting a four-cylinder, 2.0-litre engine to a near two-tonne SUV would be truly torturous.

But turbocharging has become so clever that the smallest engine in the RX range never feels underpowered. It'll serve up 175kW at 5600rpm and 350Nm at a low 1650rpm - enough to push the big Lexus from 0-100km/h in just 9.2 seconds. That power is fed through the a six-speed automatic and sent to the front wheels.

You can choose three different powertrains in the RX - a 3.5-litre V6, a 2.0-litre turbo four-cylinder, or this one, the 3.5-litre V6 with hybrid.

As a series hybrid it can run for short distances on electric only before firing up the V6 to supply charging and motivation.

The 3.5 produces 193kW/335Nm along with the electric motor. That torque figure seems low and it probably is, but that's a function of the weird way of measuring torque from a hybrid unit. The combined power figure, however, is 230kW.

The hybrid system is hooked up to Lexus' CVT auto and sends power to all four wheels. Lexus says the 450h will complete the sprint from 0-100km/h in 7.7 seconds, which isn't bad for a 2210kg SUV.

Lexus claims a 8.1 litres per 100km on the claimed/combined cycle (though we returned a much less happy number - one that started with an 11...).

Emissions are pegged at 189g/km of CO2 on the combined cycle, and the big Lexus' 72-litre fuel tank requires 95RON fuel.

The official combined cycle figure is listed as 5.7L/100km. And, uh, yeah, we didn't get that. I did manage 8.9L/100km over the week, which included a long motorway run from Sydney up to the Blue Mountains (a roughly 160km round trip).

Your love for the RX will likely depend on your priority list. Do you want the latest gadgets, a seamless multimedia interface and the kind of cool technology you can show off to your passengers?

Well, um, perhaps best keep looking, then. The in-cabin tech here feels a little off the pace now, and that cursed mouse-style controller still frustrates the bejeezus out of me.

But if a smooth, easy and quiet drive sits atop your list, then the RX 200T will grab you in all the right places.  Probably most impressive, it doesn't feel overly large and cumbersome, and is equally at home in the cramped inner city as it is eating up kays on the freeway.

The gearbox is silky-smooth seamless, switching between cogs without you even noticing, and the cabin is commendably quiet - especially when you're coasting though the ‘burbs - locking the worst of the outside word out of the cabin. The ride has clearly been engineered to iron out small, sharp road imperfections, but you can bounce around a bit in the cabin over speed bumps.

There was a time not so long ago when the thought of fitting a four-cylinder, 2.0-litre engine to a near two-tonne SUV would be truly torturous.

You can spice things up a little by selecting Sport or Sport + via the central dial and, while there’s no noticeable change in exhaust, the accelerator gets noticeably more sensitive and the gearing more aggressive; more wiling to hold a lower gear for longer, squeezing the most out of that little engine. 

It can feel a little heavy when you first brake into a corner, but beyond that the steering is smooth, predictable, and without a lot of dead-air play. It’s not a sports car by any measure, but it doesn't feel like you’re constantly dragging a big, heavy SUV around, either. 

But be warned, it’s not the most engaging of drives. This is not a car you'd ever wake up excited to run out to. It’s comfortable, capable and engaging enough, sure, but it never really stirs your emotions.

Right. So this is a salutary lesson about tyre pressures. The first few days the tyres were only pumped up to 200kpa (29psi). That's an easy 100kpa (14psi) short of the required 300 (43psi).

Every time I, or my wife, went around a corner, the big Dunlop Sport Maxx SPs would squeal and squirm and it was most unsatisfactory.

So check your tyres, because the extra 100kpa makes all the difference. Also, the number of service stations it took to find a working pump was unacceptable. Pull your socks up, Sydney.

Anyway.

Correct tyre pressures enacted, the big Lexus turned into a comfortable, competent cruiser. Its motorway performance is super-impressive, purring along the M4 and it's ridiculously poor surface like it was born to it. Which it sort of was.

The hybrid drivetrain allied to the CVT is mostly whisper quiet. It's not the most responsive combination, the initial step-off of the electric motor's torque soon giving way to the rubber band effect of the transmission.

It doesn't feel as swift as the claimed 7.7 seconds and it would be nice if the drive select dial made a genuine difference to the throttle and transmission's response.

In the city, it's a proper wafter, moving about the broken down city streets of Sydney without fuss and a plush ride that's a bit of a surprise given the huge wheels and substantial weight of RX.

It's all very easy and pleasant but the wild looks do not match the experience. Which is not a criticism, just an observation.

The RX ships with eight airbags (including knee airbags for both front seats), ABS, stability and traction controls, blind spot sensor, reversing camera, forward collision warning, forward AEB and reverse cross traffic alert.

There are three top tether restraints and two ISOFIX points. 

The RX scored a maximum five ANCAP stars in January 2016.

Expect a four year/100,000km warranty, with a trip to the service centre required every 12 months or 15,000km. And when the car does have to go back for a service, Lexus has received much praise from owners for offering a choice between a loan car, or a pick-up and delivery service from your home or office.

Lexus offers a fence-sitting four year/100,000km warranty with roadside assist thrown into the bargain for the same period. 

Service intervals arrive at 12 month/15,000km and there is, sadly, no capped-price servicing.

Lexus will, however, promise you a car for the day or come and get your car from you and drop it back when the service is done. And it will be washed and vacuumed. The website makes a big deal about that.
