Lexus Rx450H+ vs BYD Dolphin

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.

Chinese manufacturers have been impressing us lately with the strides they’ve been making, and BYD is no exception with its Dolphin.

Not only does this hatch help bring the price down for prospective EV buyers, but it leaves a solid impression of a cohesive, well-built car, which is also quite a bit of fun to drive.

It’s not the fastest, nor is it the most practical, and there are a handful of downsides to its design and software, but when it comes down to it, this is simply a great value entry-level electric car.

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.

You wouldn’t know it in Australia, but BYD has a huge and diverse range of vehicles with lots of different styling approaches in its home market of China.

The cars we get here, though, consisting of this Dolphin hatch, the Atto 3 small SUV, and the upcoming Seal sedan all seem to share more or less the same curvy, futuristic theme.

Contemporary touches on the exterior of the Dolphin include the bar light and full ‘Build Your Dreams’ typeface embedded in the rear, the blocky gloss black alloy wheels (17-inch on the Premium we tested), the two-tone colour scheme, and of course, the grille-free face.

Short overhangs and a tall body seal the EV deal, with the Dolphin looking closest in its aesthetic to something like the Volkswagen ID.3 than anything else on the market. It perhaps won’t be for everyone - it’s a little more experimental than the more conventional look worn by the MG4 - but then, for others this distinctiveness may be a selling point.

The interior look and feel is the biggest surprise. Somehow, the Dolphin, despite being more affordable than its larger Atto 3 sibling, feels a cut above when it comes to its design theme and build quality.

The weirdly organic touches designed to mimic muscle fibres in the Atto 3 have been traded out in favour of something a bit slicker.

I really like the material choices here. The use of neoprene across the lower half of the dash, in the doors, and down the centre of the seats feels a lot less pretentious than the standard synthetic leathers you usually get at this price-point, and there’s an agreeable mix of plastics as well as gloss and matt finishes. 

The nods to this car’s name which are present are a bit more toned down and fit with the design in a more subtle way.

The floating door handles, designed to resemble a fin, are a much nicer piece than the weird rotary ones in the Atto 3, and the wavy touches across the top of the dash aren’t too in-your-face and add an element of intrigue. I like it much more than I expected to.

It’s clear this space is designed around the giant multimedia panel, for better or worse. It looks spectacular, it’s nice and sharp, and the software, which looks as though it’s trying to emulate Tesla, does a pretty good job.

It’s quick, sharp, colourful, and has nice large iconography to jab at while you’re on the move, although some of the driving settings are ambiguously labelled and require clicking through to a sub-menu to alter. You’d get used to it, but it isn’t as slick as a Tesla operating system.

It also rotates, because of course it does, although one quirk I found with this is the polarised coating on the screen made it impossible to see when in portrait mode if you were also wearing polarised sunglasses.

Also, Apple CarPlay doesn't work in portrait mode. A gimmick? You decide.

The floating physical rotary controls jutting out below are a also a brilliant little piece of design. On one side you have your gear shifter, and on the other you’ve got your volume control, between them there are core functions, an on/off switch and an auto button for the climate, as well as the hazard light and drive mode controls.

It would be nice to also have a fan speed and temperature toggle, as these functions can only be used through the touchscreen, but there are worse offenders for clumsy climate controls on the market.

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 clever design bits don’t end with the controls and themed motifs, either. While the Dolphin’s cabin feels a bit smaller than many of its rivals (because, physically, it is), efforts have been made to make it a versatile space. 

There are plenty of little storage areas throughout. There’s the floating one below the touchscreen, which suits wallets and sunglasses. There’s one with a roll-out cover set low below the controls which is good for smaller objects you don’t want moving around the cabin.

A large cubby is located underneath the armrest between the two seats for bigger objects and a slick wireless phone charger cut out from the top.

The two centre bottle holders are a little small, as are the cut-outs in the doors, so if you’re negotiating with an XL takeaway soft drink you might run into trouble.

The dark theme for the interior in our car doesn’t help the more closed-in feel, but the standard panoramic fixed sunroof (mercifully with a rolling shade) helps to keep the space airy.

I found it easy to set up my driving position, another clever touch being the little digital instrument panel perched on the steering column, so no matter how you adjust it you can always see it.

I was a little concerned the rear seat would be tiny, because this car doesn’t look big from the outside, but I was most definitely wrong.

Behind my own seating position, at 182cm tall, I had leagues of knee room and plenty of space for my feet thanks to the flat floor. I also had sufficient but not stellar headroom, and the soft-touch materials continue into the doors and seat trim.

I will say, the abundance of synthetic leather is much more evident for rear passengers, but it feels like a minor complaint.

Again, the bottle holders in the doors are tiny, but at least the ones in the drop-down armrest are generous. The middle seat is very useful thanks to the flat floor, although there are no adjustable air vents for rear passengers.

The backs of the front seats have a variety of pockets in different shapes and sizes, and there are USB-C and USB-A ports on the back of the centre console, alongside a bizarre centre bottle holder which is on an angle.

Boot space is 345 litres if you move the false floor to its lowest position. I was just able to squeeze in the three-piece CarsGuide luggage set with a bit of fiddling around.

With the second row down, room expands to 1310L, and you can bring the false floor up in the boot to make the load area flat.

The space underneath is quite good for storing charging cables and such, but keep in mind the Dolphin doesn’t offer additional frunk storage.

What it does offer is a vehicle-to-load adapter, which lets you power household appliances via its external charging port. Neat, and rare at this end of the EV market.

Yep. This is the new cheapest electric car you can buy in Australia. This title is a frequently moving target, but again, at the time of writing, the entry-level Dolphin variant, at $38,890, before on-road costs and state-based incentives, undercut the MG4 by just $100, and the GWM Ora by $1100.

Importantly, its starting price is now in the realm of relevant combustion rivals. For similar money, you can hop into a high-spec Corolla (ZR Hybrid $39,100) for example, so this is the first time electric cars have become so affordable for the average consumer.

There are two Dolphin variants for now. The entry-level Dynamic, and the top-spec Premium. Both share more or less the same standard equipment levels, although they are differentiated by having different battery sizes and electric motor outputs.

You can’t talk electric car value without talking range, but thankfully, despite its low price, the Dolphin delivers on this front.

The base car scores a 44.9kWh battery, granting it a 340km WLTP-certified driving range, while the top-spec Premium ups this to a 60.5kWh unit, delivering a more substantial 427km range.

The entry battery is more than enough for city commuters, while the larger battery is enough to suit intercity freeway drives.

There are also plenty of longer-range EVs on the market, the Polestar 2 and Tesla Model 3 being chief among them, but for a vehicle at this price and in this market segment, the Dolphin is a huge improvement on some mainstream offerings, like the Mazda MX-30 and Nissan Leaf which can’t offer the same price-to-value ratio.

A lot of BYD’s ability to provide such an appealing price and driving range is down to its battery technology.

Unlike other automakers which need to buy batteries from suppliers, BYD designs and builds its own batteries, using an LFP chemistry which is cheaper and uses fewer scarce materials while offering economies of scale as well as the exact right size and form factor for its vehicles.

If this leaves you thinking the Dolphin must be sub-par when it comes to standard inclusions, you can think again, because this car also delivers with 16-inch alloys, LED headlights and tail-lights, a massive 12.8-inch multimedia touchscreen with built-in nav as well as Apple CarPlay and Android Auto connectivity, a wireless phone charger, electrical adjust and heating for the front seats, keyless entry with push-start ignition, climate control, and a comprehensive suite of active safety items.

Not bad at all, and the interior blend of neoprene and synthetic leather feels a bit nicer than the base MG4's cabin, for example.

The Dolphin might be as cheap as it gets when it comes to an electric car, but the value on offer here speaks for itself.

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.

There’s the choice of two powertrains for the Dolphin. Both are single-motor front-wheel drive set-ups.

The base Dynamic can make use of 70kW/180Nm which sounds underpowered to me, but the car we tested for this launch review was the Premium which offers a much healthier 150kW/310Nm.

As well as the increase to battery capacity the Premium upgrades the suspension to a rear multi-link set-up.

While the base car seems like such a value buy, the increase in power, ride quality, and range seems to justify stretching to the Premium if your budget allows.

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.

As previously mentioned, each variant also gets its own battery capacity. The entry-level Dynamic offers a 44.9kWh battery and 340km of driving range, while the top-spec car offers a 60.5kWh unit with a driving range of 427km.

Charging on a fast DC unit maxes out on 60kW for the Dynamic or 80kW for the Premium.

This sounds slow, with many rivals offering in excess of 100kW charging at a minimum, but because the Dolphin’s battery sizes are so trim, it still means an 80 per cent charge will arrive in a little over half an hour.

On the slower AC charging standard, the max speed is a disappointing 7.0kW. For a fully electric car, we prefer to see at least 11kW as it makes it worthwhile to plug-in to an AC unit at a shopping centre to add roughly 70 - 100km of range an hour.

Because the Dophin is also quite efficient, though, you can still expect about 50km an hour to be added on this charging standard.

Official energy consumption for the Premium as-tested is 14.2kWh/100km, and we saw an impressive 14.1kWh/100km on our brief test program, making it one of the more efficient EVs I’ve ever driven.

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.

The Dolphin is immediately impressive. From the get-go I was greeted with a feeling of quality from the car in ways I didn’t expect. The steering feels nicely balanced and not too artificial like it can be on some EVs, while the interior is refreshingly ergonomic.

The ride might be the Dolphin’s most impressive trait, with a feeling of balance across both axles, and a spritely feel to the whole car.

It is trim for an EV, with a kerb weight of 1658kg, which no doubt helps the steering feel, and the efficiency.

As it is, I didn’t experience the kind of crashing and wallowing many EVs suffer from on larger bumps, and smaller bumps seemed to be filtered out with ease.

It even feels nicely balanced in the corners, pairing nicely with the great steering feel which is not something we’ve come to expect from Chinese cars.

The motor is also willing, with software tuning keeping power delivery on the right side of overwhelming, although the warm-hatch equivalent's seven second 0-100km/h sprint time is a hint at what it’s capable of.

Unfortunately, it is let down by a pretty sub-standard factory tyre package. The LingLong Comfort Masters are designed for the Dolphin, complete with little Dolphin markings on them, but are hardly inspiring for traction when you plant the accelerator or tip it into a corner with enthusiasm.

They are better than the pretty much no-name Atlas Batman A51 tyres which came on the Atto 3, but even MG has wised up to putting tyres from renowned manufacturers on its Australian-delivered cars.

The Dolphin is also easy to park, thanks to its excellent surround camera suite and tight footprint, but visibility out of the tiny rear window is limited and made worse by the huge headrests for the outboard back seats.

In terms of electric driving characteristics the Dolphin offers two levels of regen braking, one which is virtually non-existent, and another mild tune.

Surprisingly, there’s no single-pedal mode, and the Dolphin leans on blended braking more than some of its rivals. It feels a lot more traditional to drive in this sense, so may be well suited to someone hopping out of a combustion car.

The drive modes are quite dramatic, with 'Eco' mode limiting motor torque and even switching off the climate control, while 'Sport' will make bouts of wheelspin a bit too easy by upping the response time from the motor. I found it best to stick to the nicely-balanced 'Normal' setting.

Tl;dr? The Dolphin is impressive. It’s responsive, relatively light, and has a sense of quality to it through its great ride and decent handling. Not bad for the cheapest EV in Australia.

The Dolphin was recently awarded a maximum five-star ANCAP safety rating and is equipped with seven airbags and a robust list of active safety gear.

There’s auto emergency braking, lane keep assist, blind-spot monitoring, driver attention alert, rear cross-traffic alert, front cross-traffic alert, traffic sign recognition, and adaptive cruise control.

It’s one thing to have great active safety items, it’s quite another to calibrate them well so they don’t interfere with the driving experience.

The Dolphin does okay on this front. I found the lane keep system could occasionally be alarmingly heavy-handed, although it activates less than the very annoying system on my Haval Jolion long-termer.

The pre-collision alert also triggered several times due to parked cars on the side of the road, but turning down the sensitivity seemed to solve this problem.

Also included is an excellent 360-degree camera suite, ISOFIX points on the rear outboard seats, a ‘child presence detection’ system, which apparently sounds a warning if you leave a child in the back seat, and turns the air conditioning on if you ignore it, and there's even a tyre pressure monitoring system to top it off.

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.

The Dolphin is covered by a six-year or 150,000km warranty, which beats a lot of mainstream rivals for its duration, but not its distance.

In the EV segment it plays in, though, things are a bit tougher, as its primary Chinese rivals, GWM and MG, are offering seven year and unlimited kilometre warranty promises.

Service pricing is available all the way out to 96 months or 160,000km, averaging $299 per year for the duration, which is pretty good.

Many rivals are offering free servicing for several years, and there are also many electric cars which only need to see a shop once every 24 months or 20,000km, compared to the Dolphin’s more traditional 12 month intervals.
