Lexus Rx450H+ vs GWM Haval H6GT

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.

The new GWM Haval H6 GT Ultra PHEV has got to be one of the few plug-in hybrids that makes sense to me, given I live in a regional area. The longer electric driving range and DC charging capability offers far more convenience and practicality than the usual plug-in hybrids I’ve sampled.

It’s well-priced and has enough features for the average family. So, while I don’t love everything about it, it offers decent value for money.

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 H6 GT is the better-looking cousin to the regular H6 SUV because the swoopy rear end adds some much-needed personality.

It's the 19-inch alloys, Michelin tyres and red brake calipers that add to the sporty vibe.

It looks quite large for the segment and while I’m not a massive fan of the heavy plastic moulding around the base of the car, it’s got enough charm to appeal to a wide audience.

Head inside though and you're immediately hit by a strong plasticky presence, whether it be from actual plastics in the dash and door panels or the synthetic feeling of the upholstery itself.

The sunroof and red-stitched 'GT' on the seats add something but its all rather plain and lacks some personality inside.

I do like though that there’s no transmission tunnel, which means more legroom for middle seaters in the rear.

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 most practical aspect of the H6 GT's cabin is its sheer size. It's a spacious cabin for the class and that translates to lots of passenger room in each row. Which is only let down by the relatively small boot capacity of 392L (when all five seats are in use).

The boot does feature a level loading space, a 12-volt power socket, retractable cargo cover and a powered tailgate. The latter I always appreciate with kids in tow.

There are lots of individual storage options with the front featuring a glove box large enough for an owner's manual, a middle console, two cupholders and two drink bottle holders. There's also a large shelf underneath the centre console, a dedicated phone cradle and a sunglasses holder.

In the rear there are two drink bottle holders, two map pockets and a couple of cupholders in a fold-down armrest. So plenty of choices for passengers.

Surprisingly, the most comfortable seats are in the rear which feature thick padding, good lumbar support and long seat beds. The electric front seats have heat and ventilation functions, as well as adjustable lumbar support but the lumbar sits too low and the seat backs curve in too far for them to be called comfortable on a longer journey.

The tech is made up of a 12.3-inch touchscreen multimedia system and 10.25-inch digital instrument panel and while they look nice, they're basic at best. The multimedia system is simply laid out but lacks any real customisation and doesn't have sat nav.

The touchscreen can be laggy and there is wired Apple CarPlay and Android Auto. GWM has confirmed that wireless phone mirroring is due sometime later this year.

Charging options include four USB-A ports (but no USB-C ports), two 12-volt sockets and a wireless charging pad but the pad didn't always work for my iPhone 15 Pro Max (whether that is a user or software issue, I'm not sure).

There is only one grade available for the H6 GT, which is the Ultra and it's available with two powertrains - a 2.0L turbo-petrol engine or the 1.5L turbo-petrol plug-in hybrid powertrain of our test vehicle.

Its sharp drive-away pricing of $53,990 makes it very competitive against its rivals. The BYD Sealion 6 Premium sits at $52,990 MSRP and you have to jump into the Mitsubishi Outlander PHEV Exceed ($69,290 DA) if you want to match on some of the standard equipment of the H6 GT Ultra.

While the PHEV offers a class-leading electric driving range of up to 180km, it features pretty much the same equipment as it's non-hybrid sibling but is $9000 more expensive.

The premium features include a panoramic sunroof, synthetic leather and suede upholstery, electric front seats with heat and ventilation functions, a heated steering wheel, a powered tailgate, powered and heated side mirrors and rear tinted glass.

Technology includes a keyless entry/start, 10.25-inch digital instrument cluster, dual-zone climate control, 12.3-inch touchscreen multimedia system, coloured head-up display, four USB-A ports, two 12-volt sockets, a wireless charging pad, FM/AM radio, Bluetooth, and wired Apple CarPlay and Android Auto.

However, it doesn't have a spare tyre (just a repair kit) or sat nav and there's no wireless phone mirroring. At least, not yet but GWM has confirmed that they are working on getting the phone functionality up and running sometime later this year.

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.

The new H6 GT Ultra has a plug-in hybrid powertrain that combines a 1.5-litre four-cylinder turbo-petrol engine with three electric motors, two at the front and one at the rear.

Together they produce a combined power output of 321kW and 762Nm of torque. That gives this 4WD a 0-100km/h sprint time of 4.9 seconds. So it's a quick SUV but somehow it doesn't manage to feel 'blow-your-hair-back' quick.

The engine is paired with a two-speed dedicated hybrid transmission (DHT) and the switch between the electric and engine components is practically seamless.

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.

The new H6 GT has a ternary lithium battery with a large 35.43kWh capacity. It also has a Type 2 CCS charging port, which is pretty rare but welcome on a plug-in. This system can accept up to 6.6kW on an AC charger and up to 48kW on a fast DC charger, which is great.

It means you can plug in at a DC fast charger during a road trip like a normal EV and that improves overall efficiency.

The combined fuel cycle figure is just 0.8L/100km and with the 55L fuel tank, you’ll get a theoretical driving range of over 1000km. That’s just something to consider right there. The considerable pure electric driving range of up to 180km also ensures that you can do your daily errands and school run without really touching the fuel tank. 

Which I totally proved this week after doing 469km of open-road driving and my daily 'urban' errands and only using 2.3L of fuel all week. I had two full charges during my week and that means my real-world usage beats the claimed figure at 0.49L/100km. Haval H6 GT for the win.

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 new powertrain took a few days to get used to because it doesn't behave like some of the PHEVs I've driven before. The emphasis is on EV driving rather than the ICE components. The pedals are quite stiff which takes a moment to adjust to, but the auto-hold braking and strong regenerative braking means it's difficult 'creep' forward like you can in a regular ICE car.

The one-pedal function is true one-pedal driving and if you time your deceleration right, you won't touch the brake pedal. You'll either like that or you won't but it's been nice to use this week.

The power delivery is prompt and there's a lot of power available. It doesn’t feel wicked quick like a performance EV but it certainly has enough punch to satisfy. You don’t notice when it switches between the engine or motor, which makes it a very smooth powertrain.

The steering is a little spongy but responsive enough to feel spry for quick lane changes. It's just not particularly dynamic on a winding road with the combination of the firmer suspension and soft steering.

Road noise can creep up at higher speeds and there is an annoying whirring sound from the motors that my son likened to a dull aeroplane engine roar.

The suspension is on the firmer side and you notice the bumps but you also don’t wince when you hit one. Visibility is okay but the thick A-pillar can get in the way when you're scanning the road at intersections, and the back window is narrow. A digital rear-view mirror would be a handy feature for the model.

The H6 GT Ultra PHEV is pretty easy to park because it has a clear 360-degree view camera system and parking sensors at the front and rear. The 12-metre turning circle makes it pretty friendly in a carpark, too. 

The Haval H6 GT has a maximum five-star ANCAP safety rating from testing done in 2022 and scored 90 per cent for adult protection, 88 per cent for child protection, 73 per cent for vulnerable road users and 81 per cent for safety assist.

It features seven airbags, including a front centre airbag. 

There are seatbelt reminders (all seats), hill-start assist, tyre pressure monitoring, front and rear parking sensors, surround-view camera system, adaptive cruise control with stop and go, rear cross-traffic alert, lane keeping aid, lane departure alert, rear collision warning, forward collision warning, traffic sign recognition and a driver monitoring system.

The autonomous emergency braking (AEB) with cyclist, pedestrian, car and junction turning assist is operational from 5.0 - 85km/h (up to 150km/h for car detection).

There are two ISOFIX child seat mounts and three top tether anchor points and the rear seat is wide enough to accommodate three child seats side by side.

The driver assist features seem to work smoothly most of the time but I did find the driver attention monitor a bit annoying, as you get a few more chimes than you need and the lane keeping aid feels too jerky.

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.

GWM offers the H6 GT with a seven-year unlimited kilometre warranty, which is becoming the normal term for the class and you will enjoy five years of roadside assistance through Allianz.

There is also a five-year capped-price servicing program that costs $1680, which is competitive. The first service is at 10,000km but subsequent intervals are spaced at every 12 months or 15,000km.
