Tesla Model Y vs Lexus RX450H

What's the difference?

Tesla promised wholesale improvements to the Model Y, and this Juniper update delivers where it counts. But with increased, and sometimes cheaper, competition arriving every day, the pressure remains on Tesla to keep the Model Y ahead of the pack.

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 The media/sat nav system is hopelessly outdated and the drivetrain fails to deliver a significant performance or fuel benefit (although, given its 2.2 tonnes, perhaps it delivers a miracle).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

We’re not talking massive changes here – more a modernising of the Model Y offering that doesn’t really change the shape or dimensions. 

The most noticeable changes outside are the front and rear light bars, spanning the width of both the bonnet and the boot. They’re a nice touch, and seriously soften what many (including me) consider the worst angles of the Model Y. There are also new headlights, a refreshed front bumper and a new look for the alloy wheels.

Inside, it is the absolute definition of pared-back minimalism. In fact, some could argue it’s gone a little bit too far.

There are no physical buttons anywhere but on the steering wheel, and there's just the one stalk, which has the sole function of operating the indicators. Everything else - mirrors, windscreen wipers, headlights etc - are accessed either through the steering wheel, or through the central screen.

And that includes the gear selector, which is now a swipe-down-for-reverse, swipe-up-for-drive function on the central screen. You might love that, but I don't. I'm sure I'd get more used to it, but initially it did nothing but slow down how quickly I could get the car moving.

Helpfully, the central screen is big and very easy use, and logging into Spotify and Apple CarPlay does largely negate the missing phone mirroring – though if the function exists, I couldn't get it to read my incoming texts to me.

Our test car's cabin was black but highlighted with quality-feeling fabric panels in the doors and on the dash, which are then framed by a metallic-feeling mesh, helping the Model Y's cabin feel definitely elevated from the vehicles that came before it.

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 new Model Y stretches 4792mm long, 1982mm wide and 1624mm tall, and the practicality perks of the outgoing model still shine strongly in this new version.

Climb into the backseat and you’ll find a seriously spacious area, and one that feels even bigger and lighter thanks to the completely flat floor and the glass roof.

Even sitting behind my own 175cm driving position, there was ample knee and headroom, and the addition of the 8.0-inch rear screen, which supports two headphone connections, is a clever touch. Gone are the mind-numbing days of staring out the window on long family road trips. Now, kids get access to YouTube, Netflix and a heap of games.

There are also two USB charge points, and a pull-down divider that separates the comfortable rear seats. The door pockets front and rear are sizeable, and cabin storage abounds, including a hugely deep storage bin that separates the front seats.

Open the boot, and remove the shade, and you'll find another fairly massive storage area, including a deep hidden area under the boot floor. But you won't find a spare tyre – instead Tesla offers a 24-hour call-out service for the life of the warranty, where someone will come and repair or replace your tyre, should you have an issue.

Tesla isn't good at detailing specifics about its vehicles, but says you can expect a total 2138 litres of storage space in the Model Y, presumably with the rear seats folded flat and measured to the ceiling.

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.

Again, Tesla keeps its cards close to its chest on specific outputs, but data we've seen points to this Tesla's rear-mounted electric motor producing 255kW, a smallish increase from the 220kW of the outgoing model.

Tesla says that's enough to produce a sprint to 100km/h time of 5.9 seconds.

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.

Again, more cloak and dagger from Tesla here, but most reporting suggests a 75kWh battery is housed beneath the new Model Y.

We do know that our rear-drive Model Y will deliver a claimed 466km driving range on the WLTP cycle.

Charging is capped at a reported 220kW, with the brand suggesting 238km in driving range can be added in 15 minutes when using a 175kW Supercharger. Home AC charging is capped at 11kW.

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).

Reviewing a Tesla Model Y at the moment is no mean feat. The company's very public figurehead is fighting for a front-row grid position in the battle for world's most unlikeable human at the moment.

But anyway, journalist hat on, personal views aside, Tesla has done a good job with the new Model Y. I actually didn't much like the outgoing model – the ride was too harsh, the steering too darty and the cabin too austere – but Tesla has comprehensively overhauled each of those drawbacks to create a car that is genuinely much better than it has ever been before.

Let's start with the cabin. It's still austere, but the quality feels higher and more premium, and while I'll die on a hill of the screen-controlled drive selector being a bad idea, it is otherwise now a nice place to spend time. The screen and the software powering it largely replace the perks of Apple CarPlay, and the addition of the rear screen is a very good one, too.

But the biggest improvements are in the way the Model Y drives. It's far more compliant on Sydney roads, while the steering sensitivity has been dialled back so it doesn't feel as though you're constantly making corrections.

I also like the power delivery in the RWD. It's not lightning fast, but the grunt is constant and feels really instantaneous and usable.

It's no sports car, though. Our test car took in some of the windiest roads in greater Sydney and beyond, and while the body roll and composure feels on point, the Model Y does struggle with really sharp cornering. The aggressive traction control was a constant passenger on the really challenging stuff.

Overall, the improvements are good, and very noticeable.

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.

Underwhelming, I'm afraid. A four-year/80,000km warranty might be the worst offered by any mainstream brand in the country. For the record, five-year/unlimited km is now the minimum standard, with many brands far exceeding that.

Servicing intervals are a bit scattered, with the brand instead listing when things need to be done, rather than a traditional schedule.

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.
