Mini Cooper vs Lexus Rx450H+

What's the difference?

The new petrol Cooper range very gently evolves the upmarket Cool Britannia cliché BMW invented with the R50 back in 2001 and fostered with every iteration since.

More of the same, only slightly updated and just improved enough to justify trading the old one in. If this appeals to you, then go for it. This is the best petrol version yet. Probably.

But the Cooper’s real spark literally and metaphorically lies within the EV version.

Two very different Minis indeed.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

You’ve got to hand it to BMW.

The new nose and triangular tail-light treatment on the 2013-vintage midsection look as if they were designed to all go together back in the day.

You could even mistake it for the previous Cooper EV, though side-by-side that’s less likely, since the latter ditches the upright windscreen for a more raked item, clamshell bonnet opening, horizontal bumper shutlines for shorter and more-angled ones, plastic wheel arch surrounds and pull-out door handles for flush units.

The wheels are further apart, the overhangs shorter and the lower-side surfacing broken up by an artful sheetmetal crease.

The overall length at 3876mm, width at 1744mm and height at 1432mm have increased by 55mm, 17mm and 18mm respectively over the old model, but the 2495mm wheelbase stays the same.

And that’s not all.

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 previous Mini 3DR featured a messy and quite overbearing dashboard design from 2013 that’s aged about as well as Robin Thicke’s videos from that year.

In contrast, the new model's is far simpler and less protruding, dramatically boosting the sense of space and light.

That said, all four occupants still sit low, with an upright windscreen ahead and beside high window sills. There’s an oversized, circular screen in the middle of a pared-back dash and a neat row of toggle switches below. It’s still pure Mini in theme.

As before, there’s enough space for even the tallest people up front, reflecting the British icon’s German packaging, with plenty of head and legroom, as well as ample width. It’s only when you jump from the EV to the petrol Cooper that you realise this feels noticeably narrower.

All Coopers regardless of fuel share the 240mm (9.4-inch) central OLED display. It might seem like visual overload at first glance, with so much going on, but after a brief period of familiarisation, the touchscreen becomes a cinch to decipher and navigate. The colour-coded driving modes, pleasingly slick screen swipe action and ultra-crisp graphics are especially noteworthy.

Revel, too, in the twist engine starter and toggle gear selector actions, that also save space and are super natural to operate. This is button-lite dashboard de-cluttering done right.

As with the previous model, the Mini’s driving position has you sitting upright, but it’s comfortable enough on the S’ sports seats we sampled this on, and everything is within reach. There’s sufficient storage. The ambient mood lighting is fun. And kudos for the deployment of animal-free materials. In fact, the Cooper’s fresh textures are quite remarkable.

We’re less fond of the glass roof with no sunlight block; there are blind spots due to the thick side pillars; and some of the lower-placed plastics do not seem $60K’s worth in a supermini this expensive.

Rear-seat access isn’t graceful, with a narrow aperture to squeeze past and a slow-moving electric seat to wait for, but that should surprise nobody given this car’s size. There’s enough space for two adults and not much else really. It’s pretty basic back there.

And even further back, Mini quotes just 210 litres VDA of luggage capacity, rising to 725L with the twin backrests dropped.

Don’t forget, though, that no spare wheel exists. Just an ever-fiddly tyre repair kit.

Meanwhile, at the other end of the Cooper…

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.

Compared to the previous model, the new one brings more performance to the table.

The Cooper C uses BMW’s 1.5-litre three-cylinder turbo petrol engine, and pumps out 115kW of power at 6500rpm and 230Nm of torque from 1500rpm to 4600rpm. Previously it was 100kW and 220kW.

With a power-to-weight ratio of 91.3kW per tonne, it’s enough for a zero to 100km/h time of 7.7 seconds (previously 8.1s), on the way to a 225km/h top speed.

Mounted transversely, it drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It’s still difficult to imagine Mini buyers not outraged by the manual’s disappearance. But don’t worry. There’s always the Suzuki Swift.

Stepping up to the Cooper S, you’ll find a 2.0-litre four-cylinder turbo-petrol unit delivering a useful 150kW at 6500rpm and 300Nm between 1450rpm and 4500rpm. It was 141kW/280Nm in the old version.

Boasting 117kW/tonne, this one needs just 6.6s to 100km/h and can achieve a 242km/h V-max.

Now known as the FAAR platform, it is an evolution of BMW’s UKL (Untere Klasse, German for ‘lower class’) modular architecture that debuted in the previous model.

Suspension is via MacPherson-style struts up front and a multi-link independent rear end.

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 Coopers enjoy a drink more than before. By almost half a litre per 100km more, in fact.

Rated at Euro6 and running on 95 RON premium unleaded petrol, the Cooper C averages 6.0L/100km (F56: 5.6), while the more-powerful Cooper S ups that to 6.3L/100km (F56: 5.8).

In terms of carbon dioxide emissions averages, this translates to 137 and 145 grams per kilometre, respectively. With a 44L fuel tank, the potential range-average is up to around 730km.

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.

So far, similarities in design, packaging, dashboard presentation and suspension layout suggest that the electric Cooper and petrol Cooper would be like fraternal twins from behind the wheel.

But in reality, the petrol-powered Mini feels much the same as the previous model, whilst the EV is more akin to what we secretly wish the fantasy Tesla Model 1 would be like. From the future.

Now, we never had a chance to drive the Cooper C, but the closely-related (though larger and heavier) Countryman C sibling – complete with the same powertrain – proved to be a willing and feisty performer once on the go, after what seemed like protracted turbo and DCT lag.

Why the hell can’t Mini just offer manuals again?

The Cooper S, meanwhile, completely lived up to brand expectations, with the familiar, revvy snarl of BMW’s sophisticated 2.0-litre four-pot turbo providing punchy of throttle response and effortless cruising capability, though there’s still some initial acceleration hesitation.

Thankfully, the Mini’s steering is always alert, offering precision and agility by the bucketful, backed up a chassis that seems permanently glued to the road – even in the wet and wintry conditions we had to endure.

Yet, other than a ride quality that seemed better than any previous-gen Mini we’ve ever encountered and so genuinely surprised us, the Cooper S seemed a little… stale compared to the glorious SE EV we had just (reluctantly) surrendered.

A bit like having a favourite dish as leftovers for two nights in a row, it felt a bit passé in 2024, even when surrounded by that dazzling OLED dash and glitzy ambient lighting.

In every important metric – performance, handling, roadholding, ride quality, packaging and (particularly) refinement – the battery-powered Cooper is the more vibrant and alive option. And truer to the vision of the original’s creator, Alec Issigonis, as a result.

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.

Like all Minis, the Cooper comes with a five-year/unlimited kilometre warranty and five years of roadside assistance.

There are no set service intervals, as the car’s onboard computer will alert the driver based on condition and wear/tear. That said, we recommend going every 12 months or 10,000km, just to be on the safe side.

Mini also promotes several prepaid service plans on its Australian website. According to BMW, “… both new and used Mini owners can upgrade to a MINI Service Inclusive plan for 5-years/80,000km (whichever comes first).”

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.
