Porsche Panamera vs Lexus Rx450H+

What's the difference?

The Panamera is the ‘have your Porsche and drive it too’ model.

It encompasses the fun of the 911 while still being a comfortable daily driver that can easily fit a family of four. The cabin is sumptuously styled and not hurting for features, either.

Could the ownership costs and storage be better? Probably, but if you’re looking at this model, those items will probably be lower priorities for you.

For my little family of three, the base model Panamera is a win.

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.

This is more than just a new Panamera - it’s a new generation Panamera.

The outgoing model was sort of a mix between the 911 and Macan but didn’t really hit the mark with any of its borrowed elements.

Beauty is in the eye of the beholder but the redesign sees this model get an outward appearance that looks far more aggressive with a distinct profile that now sets it apart for all of the right reasons.

On the outside, the biggest changes include larger matrix LED headlights and a new front fascia that sits a bit higher with more pronounced curving in the bonnet.

The front gets extra air intakes but there are also larger 'air blade' vents behind the front wheel arches which help smooth the air flow around the wheels and add some extra sculpted sportiness to the car's sides.

The rear has been reshaped to look more like the 911 and isn't as pillowy as the outgoing model. There is a new long LED strip light running the width of the rear and an extra brake light for added dazzlement at night. The rear window now spreads to the width of the liftback lid which makes it appear frameless.

The optioned 21-inch alloy wheels look gorgeous in their painted bronze (or Neodyme) glory and feature the Porsche crest in full colour for added pizzazz. The bronze accent is also carried across to the quad exhausts.

All these factors make the exterior design look more cohesive than the previous model.

The interior has been reworked, too, and the dashboard now sports upgraded tech panels that makes the cabin feel cinematic. The optioned passenger display screen only adds to this effect.

Purists will pout, but like the new 911 the analogue cluster and turn-key operation have died a quiet death. You now get a 12.3-inch digital instrument panel and push-button starter. Plus, the gearshift has been repositioned from the centre console to the dash.

The optioned Sports Chrono and Neodyme accent packages of our test model means the dashboard gets a race clock (superfluous for every day driving but fun to look at) and the door handles, steering wheel and dashboard feature the same bronze highlights.

The only elements that don't look the part are the shiny piano black panels mainly found in the centre console. They're too easily scratched/marked for a car at this price point.

The cabin may not be as flashy as its competitors but it's still sumptuous.

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 cabin feels spacious in both rows and the rear row can comfortably fit those who are above six foot (182cm) with a caveat.

Despite being optioned with the '4+1' seating, don't be fooled; the middle rear seat is nothing more than extra room for the out-boarders as the rear centre console takes up all legroom a middle seater might need. Not even a kid will be happy in the middle for long.

Amenities in both rows are good. The heating/cooling and massage functions on the front seats are great and the four-zone climate control means everyone can get comfortable.

Access to both rows is surprisingly good with doors that open widely but the rear footwell lip is high and the well narrow. So, if you have clunky boots on you may feel clumsy getting into position.

My seven-year old found the doors heavy to open and it took him a while to realise he didn’t have to slam the doors shut thanks to the soft-close feature.

Individual storage is better than you usually get in a sports car but all cubbies still fall on the shallower side. There are four cupholders, four drink bottle holders, a glove box, a middle console and two small net map pockets. There is also a dedicated phone cubby housing the wireless charging pad.

The boot aperture is wide and it’s super easy to reach things in the back thanks to the liftback lid but that sloping roofline means you lose out on height for larger items.

Stack bigger things right behind the back seat if you want to fit them. Capacity is below average compared to its rivals at 460L.

The rear row has a 40/20/40 split to open up storage options and there is a very deep cubby underneath the floor with the tyre compressor/repair kit.

Device charging options are great with a total of four USB-C ports, a wireless charging pad and three 12-volt sockets to choose from.  

The upgraded multimedia system looks fantastic and is user-friendly. The built-in satellite navigation is simple to use and the multimedia system, head-up display and instrument cluster can be highly customised.

The base Panamera model now comes standard with wireless Apple CarPlay and Android Auto. Connecting to the CarPlay is easy and the connection remains seamless.

The optional passenger display panel allows the front passenger to control their climate and seat comfort, see a duplicate of the instrument panel or just watch a movie on a long trip.

The screen has a privacy filter, which means the driver can’t see what’s on it and is thus not a distraction. However, no one in my family bothered to use it.

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.

The base Panamera doesn’t have a hybrid powertrain like its siblings and sports the 2.9L V6 twin-turbo petrol engine of the outgoing model. But it’s been retuned and now produces 260kW and 500Nm – both figures up from the previous model.

The Sport Chrono Package means the 0-100km/h sprint improves from 5.1-seconds to a tummy-sucking 4.8-seconds and my son gave a whoop of delight whenever we had to get up to speed.

The Panamera has an eight-speed, dual-clutch auto transmission and is the only RWD for the Panamera line-up. It also sports a top speed of 272km/h. So, suffice it to say, the engine has the sports cred you expect from a Porsche.

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 official combined (urban/extra-urban) fuel-cycle consumption figure is 9.5L/100km, which is pretty low for a high-performance vehicle (and a big one at that) but after a lot of open road and urban driving my real-world usage came out at 10.9L/100km.

That's the result after not being skimpy with using the power, either, so it's not as thirsty as you might expect.

When it comes to times between fills, the Panamera might surprise you. Based on the official combined fuel cycle and large 90L fuel tank, expect a theoretical driving range of up to 947km (825km using our on-test figure) – which is a great driving range for a performance vehicle, let alone a family one.

The Porsche Panamera only drinks the best, so while the driving range is great you won't be able to fill 'er up with anything but premium 98 RON unleaded petrol.

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.

Some people might not understand the obsession or loyalty Porsche owners have towards their cars  but if you’re a fence sitter, get in the Panamera. It will make you understand because after driving one... you'll hear yourself say 'I get it'.

The base model has the goods with the engine outputs to ensure the driving experience remains fun and responsive.

The Panamera is no wild bronco, it's a cool customer. The composure for power delivery is unlike other performance sedans you may have driven. Acceleration is effortless without any twitchiness. You never feel out of control.

The air suspension means you hear the bumps more than you feel them but you still get excellent road feedback as a driver.

Passenger comfort is high, despite the cabin being quite loud with road and engine noise, because the seat and ride comfort remains well-cushioned. Fatigue and jostling are at a minimum.

The handling of the Panamera when it comes to cornering and steering feels dynamic and agile. I made a point of doing multiple mini roadies this week, simply for the joy of driving it.

While the Panamera is the most fun on a winding mountain road, it's a pleasant open-road cruiser as well.

The base Panamera has three driving modes - 'Normal', 'Sport' or 'Sport Plus' with a 20-second power booster available when you need extra oomph.

The Normal mode is sufficient for daily driving and the Sport Plus offers stiffer suspension and handling but the preference is to keep it in Sport mode.

Mainly because in this mode you get an awesome throatiness from the exhaust as well as the dynamics you expect from a sports car.

It’s a bit deceptive but the Panamera is massive and sits at 5052mm long and 2165mm wide - so, it definitely fills out a parking space!

However, the 360-degree view camera system is one of the best in the segment but you may still get choosy with where you park it.

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.

Porsche offers the Panamera with a three-year/unlimited km warranty, which is less than its competitors. It's more typical to see a five-year/unlimited km warranty in this segment.

Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first and pricing varies per dealership.

The one I contacted (in Sydney) confirmed the first four years of servicing costs $8605 for an average of $2151.25 per workshop visit.

Worth noting the fourth year is a biggie at $4875, this major service including everything from an air-conditioning clean and transmission oil change to spark plug check/replacement and safety checks.

The Panamera is up there for service costs, even for the class but this kind of outlay comes with the territory when you're considering a car worth almost $300K. 

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.
