Lexus Rx450H+ vs Toyota Prius V

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

No, the Prius V isn’t exciting. But it does what it’s designed to do - move families in decent comfort without using much fuel. And if that’s what gets your (hybrid) motor running, then you really ought to take a closer look.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

The world was a different place when the Toyota Prius V came out. Back then, the iPhone 4s was at the cutting-edge in phone design, Gangnam Style was smashing it on the charts, and car design was in a very different place.

There are some signature Prius elements, with a swept, aerodynamic looking roofline and sleek front-end styling. The facelift that was applied to the Prius V in 2015 saw sharper lines and more aggression, but it arguably doesn’t have a lot of aesthetic appeal given the way Toyota has evolved its design since then.

It isn’t a traditional people-mover, because it has regular doors at the back rather than sliding doors to allow simple access to the third-row seats. It’s more like a hatchback that’s been stung by a bee, looking a bit bloated. But as one pint-sized tester put it this week, it’s one very big little car.

The inside is a bit of a marvel in terms of space management. This car measures just 25mm longer than a Corolla sedan (4645mm long), and it's only 1775mm wide (the same as a Corolla sedan) and 1590mm tall, because it needs a bit more room to fit seven people in. And it can.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

The cabin of the Prius V highlights the notion of versatility. There are two rows of seats at the back, with the middle row sliding and folding to allow easy third-row access. And I mean easy - even me, a 183cm-tall human - can clamber into the back seats without too much in the way of old-man noises.

The space in the back row is limited, though, particularly for knee room and foot space. It is best left for children, then. But the second row has three individually slide-able seats, meaning if you really need to fit seven adults in, you theoretically could.

That second row is nicely useable. The fact the seats are sculpted individually means they feel made for a proper family getaway, and even with them set as far forward as they can go (to allow maximum legroom in the third row) I could sit in the outboard seats without much discomfort. The sun-blinds that are built into the back doors are a really welcome touch for parents and adults alike.

What isn’t so great is the lack of rear air-vents - there aren’t any face-level vents in either the second or third rows, meaning things could get stuffy on a hot day.

But the practicality side of things is reasonably well sorted, with useable cup holders in the rear wheel arch moulds, plus there’s a 12-volt outlet in the third row, too. The middle row has bottle holders in the doors, and there are map pockets in the front seatbacks. 

Up front there is more smart storage; a pair (yep, two) of gloveboxes adorns the dashboard, and there’s a pop-out cupholder on the passenger side, too. Two more cupholders grace the centre console (which itself is very shallow, because the hybrid batteries sit inside it), plus a small storage box - presumably for your keys to sit. A small shelf sits at the bottom of the centre stack, and that’s where you’ll find a USB port to connect to the media screen above.

That 6.1-inch touchscreen is fine, but pretty ancient. It has some small menu buttons, won’t allow you to input phone numbers or connect to Bluetooth when the car is moving, and you (or your fellow front passenger) can’t manually enter sat nav details when you’re driving. There is voice control, but it’s painful. Forget Apple CarPlay and Android Auto, too - neither is available in the Prius V. 

While the boot space is pretty limited with seven seats in place - Toyota claims 180 litres of capacity in that configuration - there’s still enough room for a suitcase or two. 

But with five seats in play it makes quite a bit more sense, more easily fitting family things like prams with its 485L of cargo capacity. And remember, there are no batteries under the boot floor eating into space, and you get a space-saver spare wheel as well.

Not only is the Prius V the most affordable seven-seat hybrid car on the market, it’s also the cheapest Toyota with seven seats. 

It undercuts the Tarago, Kluger and Land Cruiser Prado by a decent margin, with pricing starting at $37,590 for the base grade model and stretching to $45,380 for the top-of-two-tier i-Tech flagship. Should you bother spending up on that version? In short, no.

That’s because the regular Prius V has a pretty strong standard equipment list. Push-button start, keyless entry, sat nav with SUNA live traffic updates, a reversing camera, climate control and a head-up display are all standard. You also get 16-inch alloy wheels, which have a set of plastic wheel covers over the top (great for kerb touch-parkers).

The i-Tech sees the addition of Bi-LED headlights with auto-levelling (as opposed to the halogens with LED daytime running lights you see on the base model), plus fake leather seats (not cloth), heated front seats, a dual-pane panoramic glass roof (which doesn’t open), an auto-dimming rear-view mirror, and a semi-automated parking system. 

Plus, whether you choose the entry grade or the high-spec, you get Toyota’s 'Safety Sense+' system - read the details in the safety section below.

Colour options for the Prius V are quite broad. There are nine rather sedate hues to choose from, with eight of them being 'premium colours' that attract an additional cost ($450). 

And, as with most Toyota models, there is a range of additional factory-backed accessories that you can choose, such as a bonnet protector, boot scuff guard and even door handle protective film (to stop rings from scratching them up), but things like roof racks/roof rails or a roof pod are unavailable.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

Powering the Prius V is a 1.8-litre four-cylinder engine, which uses a CVT auto and combines with a lithium-ion battery pack and two electric motors. It’s what’s known as a series parallel hybrid set-up.

The system can allow the car to run using both the battery and engine, or just the battery, or have the regenerative braking system feed the battery pack more juice. That tech isn’t necessarily cutting edge today, but it was when the car launched (waaaaay back in 2012).

The engine can produce 100kW of power and 142Nm of torque. The electric motor can produce 73kW on its own, but the maximum combined power output is still 100kW.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

Obviously if you are considering a hybrid, you’re looking to take advantage of excellent fuel consumption. And the Prius V doesn’t disappoint.

The claimed consumption is just 4.4 litres per 100km. In the real world, you can expect to use about 5.5L/100km if you’re light on the throttle, and 6.5L/100km if you thrash it. 

You can’t skimp on the fuel when you get to the bowser, though - the Prius V insists on running using 95 RON premium unleaded.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

If you’re a car geek like me, you likely find driving as efficiently as you can fun. If so, you'll love this. You can watch the car switching between EV mode - which it will use for up to about 30km/h, but only for a couple of minutes - and hybrid power. And honestly, if you’ve never driven a hybrid you might think it sounds dumb, but being a fuel miser can be fun!

But the fun factor is pretty much limited to being a cheapskate on fuel. It really isn’t that fun to drive otherwise, but that’s not what it’s designed for.

Still, the drivetrain does a decent enough job for most families - it builds pace pretty easily, and while the refinement and power could be better, if you’re not aiming to break records on the school run, you shouldn’t be too disappointed.

The ride is mostly good, though it can be a little sharp over patchy surfaces, and the steering is decent, if a little lifeless. My biggest issue is the brake pedal response, which takes some getting used to. Sometimes it feels like it won’t stop quick enough. 

That, and the adaptive cruise control doesn’t slow to a stop on the highway - it cuts out at about 30km/h, so you’ve gotta be on your toes if the traffic starts to build up.

If you want the latest and greatest in hybrid family friendliness, you really ought to wait for the new-generation RAV4, which - admittedly - mightn’t have seven seats, but it will have a hybrid drivetrain offered. And it’ll be much more modern inside and out.

Every Prius V still carries the same maximum five-star ANCAP safety rating that it was stamped with in 2015, even though the car was actually tested in 2012.

The range is covered with the safety systems you’d expect, including electronic stability control, ABS, electronic brake distribution, plus there’s a reversing camera, too. Rear parking sensors are a dealer-fit accessory.

There was a bit of back-and-forth between myself and Toyota Australia over airbag coverage. The company stated on its public site that the car had curtain airbag coverage all the way to the third row, but no image to support that. I’ve since had it confirmed by Toyota Australia that it does definitely have third-row airbag coverage, which is a great added piece of mind element for family buyers (plus there are dual front, driver knee and front side airbags, too).

Airbags are one thing, but what about the other safety kit? Well, every Prius V has Toyota’s Safety Sense plus system, with auto emergency braking (AEB), pedestrian detection, adaptive cruise control, auto high beam lights and lane-departure warning.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.

It’s cheap to run a Prius V in terms of its fuel use, and it’s cheap to run in terms of its maintenance, too. Toyota lists its charges at just $140 per visit to the dealer under the Service Advantage offer, though you’ll need to take it in every six months or 10,000km.

The warranty cover is three years or 100,000km for the car, but the hybrid battery attracts an eight-year/160,000km cover of its own.
