Subaru WRX vs Lexus Rx450H+

What's the difference?

Possibly one of the most perfect performance cars you can drive daily for the price. Dynamic and fun to drive, but also easy to live with thanks to the drive modes for extra comfort, the high ground clearance and the practicality that comes with four doors, lots of storage and a big boot.

The tS Spec B is the priciest WRX in the range, but compared to rivals it's also great value. A car I would buy with my own money for sure.

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 WRX tS Spec B stands out from its siblings with 19-inch matte-grey alloy wheels with gold Brembo brakes and if you don’t notice any of that, then surely you won’t miss the gigantic rear wing planted on the boot lid.

The air scoop jutting out of the bonnet like a pizza oven is standard across the WRX range and it looks tough. There’s the rear diffuser which also looks beefy but also a bit plasticky, and the quad exhaust, that’s nice, and so is the note which wafts out of them at idle.

The tS Spec B’s Recaro sports seats are also in other tS grades – they do look and feel good, and offer outstanding comfort and support. 

The rest of the cabin is much the same as other WRX grades with a large portrait-style screen, physical buttons for climate control, and yes, that is a traditional, mechanical handbrake you can see in images.

This is a sporty-looking although slightly outdated cabin compared with more modern rivals.

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.

What’s so appealing about the WRX is that despite it being a performance car, it’s based on a regular 'small' sedan and with that comes all the practicality of a four-door, five-seater with a big 411-litre boot.

Space inside is excellent with plenty of room up front, while rear legroom is ample enough for me, at 189cm tall, to sit behind my driving position with plenty of headroom, too.

That all said the Recaro seats up front are on the snug side and I know they’re supposed to be, but I’m just saying they might not suit everybody – and by that I mean everybody.

Those with long legs might also find they have to adjust their driving position when letting out the clutch.

Big door pockets throughout, four cupholders, and hidey-holes for items throughout make for good cabin storage.

There are four USB ports and one 12V outlet, but no wireless phone charging to be found.

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.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

Who doesn’t love the sound of a boxer engine? Well, probably your neighbours if you own a WRX. And while the tS Spec B doesn’t have any more power than any of the other WRXs – with it sharing the same 2.4-litre turbo-petrol four-cylinder boxer engine as the rest of the line-up – the 202kW and 350Nm feel like the perfect amount of power and torque for this package.

It’s probably been about six months since I last drove a car with a manual gearbox, and that shows how rare they’re becoming when you’re testing a new car nearly every week.

The six-speed manual in the tS Spec B has satisfying clunky shifts and a heavy-feeling clutch pedal, but it all plays along perfectly with this engine, sending the drive to all four wheels.

If you’re looking for a version of the tS Spec B with an automatic transmission you’ll be searching forever because this grade only comes with a manual gearbox. There are WRXs with autos – well, a CVT – the entry grade, the RS and the tS.

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 WRX tS Spec B manual really likes its fuel – it’s a hungry beastie and everybody who’s about to get into the WRX life should be aware that, like most petrol performance cars, it’s not super fuel efficient.

Subaru is beautifully honest with its fuel consumption figures, which have the the WRX tS Spec B using 10.4L/100km in combined driving and 14.2L/100km in urban environment, which is so close to what we recorded - ours was 14.1/100km after mainly urban driving. You'll also have to feed it 95 RON.

The fuel tank is a healthy 63 litres in volume and that should give you a range of 606km – in theory. Do not test this theoretical range somewhere remote, okay?

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.

This may sound strange, but a few months ago I was squished into the tiny cockpit of a 2025 Chevrolet Corvette Z06 sitting at the traffic lights wishing I was in the 2020 Subaru WRX STI beside me. And having driven so many supercars and muscle cars in the past, many costing hundreds of thousands of dollars, I still see the WRX as being such a perfect daily driver performance car.

Sure, it doesn't have Porsche 911 dynamics or the straight-line acceleration of many electric cars, but it's the way the way this boxer engine interacts so beautifully the six-speed manual gearbox, combined with sticky all-wheel drive, a wonderful balance and such direct steering that make the WRX ts Spec B feel exactly right.

The tS Spec B is very much at home in the suburbs dotted with roundabouts and obstacles like speed bumps, but they all become part of the fun of driving this car in the same way that when you let it loose and open road it performs happily and so well, too.

The suspension does feel firm, but part of the big news of this tS Spec B is that it now has a drive mode function and this allow you to adjust the suspension, the steering and the throttle response to either sporty or comfort settings. This just makes this car an even more agreeable thing to live with daily.

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 RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

The WRX tS Spec B is covered by Subaru’s five-year/unlimited-kilometre warranty, which while the standard for the mainstream segment, is behind the seven-plus terms we're now seeing from a lot of Chinese and Japanese car brands.

Servicing is recommended every 15,000km/12 months and can be expensive compared to other brands, with the five years of capped price servicing coming to $2692.

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.
