Lexus CT200h vs Lexus RX450H

What's the difference?

The cheapest Lexus of them all isn’t chasing badge snobs with the CT200h as blatantly as Mercedes-Benz, BMW and Audi do with their entry level cars… but it’s perhaps not quite the Lexus you’d expect it to be.

It has a lovely front-of-cabin, for example, but there’s a lot of last-gen Prius in plain sight in the rear of the cabin.

The hybrid powertrain, too, is noble in concept, but the day-to-day reality is that it’s not as nice to drive, especially town to town, as a regular petrol-powered car of similar size.

The foot brake, silly multimedia joystick and odd gearshifter also spoilt the party a bit.

Empty nesters who are looking for a nice city runaround with a tinge of greenwash about it will love it… and if the current Prius is anything to go by, the next CT will be a very good thing indeed.

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 The media/sat nav system is hopelessly outdated and the drivetrain fails to deliver a significant performance or fuel benefit (although, given its 2.2 tonnes, perhaps it delivers a miracle).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.

There are some light external revisions for the latest update of the compact Lexus CT200h. New grey 17-inch alloys are unique to the Sport Luxury, along with a black roof treatment, new L-shaped LED driving lamps that match new-design LED tail-lamps, while Lexus designers have also added its new spindle grille to the brand’s smallest model.

It manages to be inoffensive, but it doesn't really reflect the brand's latest design language of 'real world concept cars' like the NX and the LC ranges.

Inside, a couple of new leather colour options are available for the CT200h, while the addition of the wide-format 10.3-inch screen to the top of the centre console is the single largest change. Interestingly, the steering wheel controls appear to have regressed a little from the previous model, no doubt brought about by the addition of the new driver aids.

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.

The CT200h basically replicates a small hatchback in terms of interior size. It'll seat five, but if you try to put three adults across the back, they won't be particularly happy about it. 

The roofline is quite low and the car’s waistline is high, which makes the glasshouse feel small. Room in the front is adequate, but only just for taller drivers; the sunroof, as fitted to our test example, takes away a good chunk of headroom, despite the CT200h standing just 5mm lower than a Corolla overall. 

The seats themselves, too, are mounted just a touch high to be comfortable for taller drivers, while rear seaters will complain bitterly about being stuck behind my (184cm) driving position. However, my more diminutive wife pronounced herself very comfortable behind the wheel and in the passenger seat.

A nice, small steering wheel sits in front of a single-dial dash that sports two digital screens either side. The left-hand screen changes when you change the drive mode dial between Eco, Normal, and Sport. And there's also a full EV mode button in handy reach. 

Two cupholders are line astern between driver and passenger, although storage is at a premium thanks to the size of the car. Climate and multimedia controls - and even an old-school CD player – flow right through underneath the centre console, which steals away valuable space. There are no extras like wireless charging bays, nor is there Apple CarPlay or Android Auto.

There are bottle holders in the door, but don't try and stash anything that's over one litre in size because it just won't fit.

It's quite an austere proposition for rear-seat passengers, with no bottle holders in the doors, no cup-holders and no charging points. There are fixed vents under the front seats and on the right side of the rear area, so it's not a complete desert, and there are ISOFIX mounts for two child seats in the rear.

Another practicality issue that's unique to the CT200h is the gear shifter. It operates as a spring-loaded joystick, and unless you're watching the dash indicator, it can be tricky to know which gear you're in. Other car makers have actually recalled cars with this style of transmission stick, and it's certainly something that you have to get used to. 

Likewise, the old-school foot brake is certainly an anachronism in something like a Lexus.

Based on the previous generation Prius, the nickel-metal hydride battery for the CT is hidden underneath the rear seat, so it doesn't steal away too much boot room. However, the boot floor is still quite high, and the area is rather small at 375 litres with the seats up. There is 985 litres available when you drop the seats, but the aperture is short and narrow, so larger items will be a squeeze. There is a space-saver spare nestled away underneath the boot floor, too.

Another practicality note in the negative column is Lexus's insistence on the odd joystick control for its multimedia system. It's simply not very good. It’s imprecise when compared to a touchscreen, the action and feel of our test unit was very much less than premium, and it’s just awkward and clumsy to use. The CT is not the only Lexus to use it, but we wish the company would just see the light and ditch it all together.

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.

The 1.8-litre twin-cam petrol engine makes a relatively low 73kW and 142Nm, while a 60kW, 207Nm electric motor that’s also connected to the front wheels chips in its share.

Combined, the system produces 100kW, while the torque figure translates to around the 150Nm mark. That juicy 207Nm doesn’t come into play, sadly, given that the petrol engine – which is built to run cooler than a traditional Otto cycle engine, and therefore more efficiently – does most of the work.

Throw in a transaxle for the electric motor and a power inverter, and things are getting complex. However, if the Prius is any indication, the CT200h’s drivetrain is durable and relatively serviceable, with batteries estimated to last ten years or longer.

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.

Here’s the odd thing – over 220km of largely highway driving, I couldn’t get the CT200h under a dash-indicated 10.4 litres/100km, against a claimed combined fuel economy figure of 4.4L/100km. 

I topped the tank off with 18 litres of fuel, which works out at a closer 8.8L/100km… but it still ain’t anything like 4.4. 

Another owner I spoke to, though, said he regularly records high fives with his CT200h in mixed conditions.

It runs a 45-litre tank that’ll happily take 95 RON 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).

If you've ever driven a Prius, then you'll be very familiar with the way that the CT drives. Based around a 73kW Atkinson cycle petrol engine which focuses on fuel efficiency rather than outright power, a 60kW electric motor (the pair combine to produce 100kW in total), a nickel-metal hydride battery array and a CVT gearbox, the CT200h – like the Prius – is a bit different to a regular hatch.

Under light throttle, the CT is quiet and moves along quite well, and you can even use full Electric Vehicle mode at speeds under 45km/h for a brief amount of time, (slightly less than two kilometres), and with a very gentle right foot.

The battery array is recharged via the petrol motor as well as regenerative braking (where heat energy is captured and directed back to the electric system) – but unlike a petrol-electric plug-in hybrid, there’s no way to stick a 240v cable into the CT to top up the battery. 

It has the unusual whines and odd noises that you would associate with a partly electric car, but the petrol motor sounds just like a regular old four-pot petrol unit, and it’s running most of the time.

One issue with the drive of a hybrid is its ability, or the lack thereof, to get off the line in any sort of hurry. You really have to mash the throttle to get going, which takes some getting used to. There’s also some hesitation and un-Lexus like thumps from the drivetrain if you confuse it by almost stopping then taking off again.

The CT200h’s biggest bugbear is that the fourth generation Prius exists. Built on a more sophisticated newer-generation platform and with a more refined drivetrain, the new Prius is a great insight into how good the next CT will be – and what the shortcomings of the current one currently are.  

The CT works well in high-traffic city environs, where a light throttle foot helps get the best out of the unusual drivetrain. Lots of lag from rest is an annoyance, as is an excess of CVT whine under hard efforts, but the CT200h pootles around town very well.  

Its small size does play against it when it comes to keeping out road noise at freeway speeds, though the CT is superior to most other similarly sized cars in this regard. As an aside, its build quality is nothing short of amazing, with minimalist panel gaps, a tight interior and lashings of paint on every surface.

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.

Lexus sells the CT with an unusual four-year/100,000km warranty, which includes roadside service coverage. The battery pack has an eight-year/160,000km warranty, while Lexus would like to see you back for a service every 12,500km or 12 months.
 
It’s not just about a warranty or a service interval with Lexus, though. For decades now, its customer service record has topped all industry measures, and everyone we know who has bought a Lexus with their own money has raved about the quality of the service received. 

As well, it’s a level of service that’s provided across the range. It’s a tangible benefit of buying a CT200h. 

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.
