Jaguar I-Pace vs Lexus Rx450H+

What's the difference?

In the 1960s Jaguar used to promote its range as providing “grace, space and pace”. Nowadays, the I-Pace may as well also be known as the I-Grace and I-Space, because all three terms still ring true.

Jaguars were never cheap but the greatest hits felt like exceptional value because they were special. The same applies here. Five years might seem like an eternity, but age has not yet wearied the British luxury EV SUV nearly as much as you might imagine. Especially when optioned up as per our test vehicle.

Bereft of any post-modern brand baggage, the I-Pace remains a modern great. If only more buyers would catch on to that.

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.

Five years on, from the bold cab-forward silhouette to the high-riding crossover proportions, the I-Pace is a distinctive and handsome machine, offering progressive, flowing aerodynamics that have as much to do with function as they do with form. This is an out and proud EV.

But there’s the rub. Perhaps the disappointing sales reception is down to it being too removed from what many consumers might expect a Jaguar to look like.

Grille-aside, there isn’t enough connection with stablemates like the woefully-underrated XE or F-Pace, while traditionalists – many of them Americans ­– wanting classic XJ or XK retro schtick are also plum out of luck. Cover the badge and the styling could be from any (forward-thinking) carmaker.  

Or maybe it’s because the I-Pace, whose body is 94 per cent aluminium to help offset the weight of the batteries, looks compact in photos, like a crossover hatchback, when in reality it is surprisingly large, belying its sleek styling by packing in plenty of space inside.

Speaking of which, let’s take a closer look.

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.

Yes, compared to the vast mega screens invading most new models of today, the I-Pace’s dashboard layout is looking, well, off the pace. On first glance at least, this is definitely a product of the previous decade.

But as far as design elegance and functionality are concerned, Jaguar seems to have created a timeless piece of crafted automotive interior architecture that – consequently – holds up very well.

Or, in other words, the I-Pace provides a welcome sanctuary away from the infuriating folly of today’s faddish, fiddly and infuriatingly distracting touchscreen interiors. Maybe some old-school XJ smarts live on in this EV after all.

Look past the dated dashboard design, and the cabin’s overriding impression is of solidity and quality. No cheap plastics or rough surfaces here, just restrained luxury.

While electronic displays with very-analogue-style dial options amid digital driving data take care of the instrumentation ahead of the driver, a modestly-sized touchscreen is set at a lower plain so as to not dazzle and distract the job of vehicle controlling with data-overload, while under that is smaller display for climate control. More on that later.

Part of the Pivo Pro multimedia system, that central touchscreen is switched on and ready for use before the ignition button is even pressed, for immediate action.

No delaying-tactic welcome fanfare as the system boots up as per almost every other carmaker’s set-up, either. Just instant gratification, ironically. This dash is starting to feel like a resto-mod, with all the latest tech behind that Boris-era façade. 

Plus, besides being fast, it is logically laid out and avoids confusing sub-menus. Nice swipey action, too. Some familiarisation is required at first, but the system makes sense. And if you need volume adjustability, you turn a physical knob. As the ergonomics lords intended. Easy.

Speaking of which, let’s get the sensible stuff out the way. Because it sits at near-SUV height, the I-Pace is easy to get in and out of as long as you’re aware of the swooping roofline out back. And you sit up high, affording excellent forward vision ahead.

Sinking yourself into the front seats, the Jaguar lives up to its old luxo-barge reputation in that they’re sumptuous yet firm in back-location and support, providing hours of comfort if required.

The driving position is superb, with ample adjustment and those thoughtfully-placed switchgear and controls coming into play.

Storage is ample, with deep door pockets, a sizeable centre console bin and even a secret cubby underneath the rear seat.

The Jaguar provides five USB outlets and two 12V sockets. And ventilation is as effective as you need it to be.

Problems? Pleasingly, our Graz-built Jaguar suffered from no breakages or squeaks. It is as well-screwed together as you’d expect from a luxury SUV, so there are no issues there to moan about.

However, rear vision is poor due to the tapering rear windows and shallow tailgate glass. In turn, the back-seat area can seem a bit dark and hemmed-in without the (optional) fixed glass roof.

The glove box is disappointingly shallow. And, though simple in execution, the climate control can be fiddly to figure out at first.

Of greater concern is the counter-intuitive transmission selection, since the ‘DNRP’ buttons are placed in descending order, putting ‘Drive’ up top and ‘Park’ down at the bottom.

On several occasions, ‘D’ was selected instead of ‘P’ or ‘R’, nearly leading to unintended forward acceleration into parked cars or walls directly ahead.

As mentioned earlier, our test HSE features the optional suede dash and pillar covers; along with the beautiful woven grey flannel-like trim on Alcantara-like seats, they add a distinctive classy ambience – and that’s something that translates out back, too.

While you wouldn’t call it a large wagon, it is more than sufficiently spacious for two adults, while middle-seat space is A-OK for smaller folk only as the ceiling tapers a bit too much for taller passengers. Legroom is exceptional, thanks in part to a stretchy near-3.0-metre wheelbase.

The bench seat itself does not slide or recline, but the 40/20/40-split backrest seems sufficiently angled for comfort and support, while the cushion is sprung enough not to lead to achy thighs, even for longer-legged occupants.

Amenities include rear-facing air vents, a centre armrest with two cupholders, two USB and a single 12V port, overhead grab-handles and reading lights, (quite shallow) door pockets, four coat hooks and some under-seat storage.

Further back, the Jaguar’s boot area is set up high, so requires some lifting to get heavier objects in, but the floor is long and flat, and the overall volume is quite practical. Capacity varies from 656 litres to 1453L with the backrests dropped. You can fit a 1797mm by 1244mm object in two-seater only mode.

There’s storage underneath for charging cables, as well as straps and hooks to secure loose items. And, as mentioned earlier, buyers can order a space-saver spare if the tyre-repair kit is undesirable. Note, too, that a sizeable ‘frunk’ front trunk is good for a couple of soft overnight bags.

Overall, then, equipped as our $180K HSE was, the I-Pace’s interior is likely to impress.

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.

Built around a standalone architecture with no internal combustion engine versions, the I-Pace EV400 is fitted with two permanent magnet synchronous electric motors – one above the front axle and one located on the rear axle. Each produces 150kW of power and 348Nm of torque, for a system output total of 294kW and 696Nm.

Tipping the scales at 2226kg, this means the EV400 has a power-to-weight ratio of a very healthy 132kW/tonne, helping this electric crossover cross the 100km/h marker in 4.8 seconds, on the way to a top speed of 200km/h.

With a single-speed transmission sending torque to a motor on each axle, the I-Pace has permanent all-wheel drive.

The I-Pace’s standard suspension is double wishbones and coils up front and an integral link independent set-up out back.

Nowadays, the standard wheel size in the SE is 245/50R20, though ours was fitted with 255/40R22 – along with air suspension and adaptive dampers. These profoundly alter ride comfort. Towing capacity is 750kg braked or unbraked.

Ground clearance is usually 174mm, but with the air suspension, that increases to a handy 241mm in its maximum height setting. At speeds over 105km/h I-Paces with air suspension drop a further 10mm to aid efficiency. Which brings us to…

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.

With a 400V architecture, the I-Pace EV400 has the charging capability of most EVs, but not the Hyundai Ioniq 5 and 6, Kia EV5, EV6 and EV9, Genesis GV60 and Porsche Taycan/Audi e-tron GT fraternal twins, which have an 800V capability.

Under the floor is a 90kWh lithium-ion battery, with a useable capacity of 84.7kWh.

For AC charging, it uses a Type2 connector with 11kW capacity, or for DC fast charging, it has a maximum 104kW capacity via a CCS port. Both are located in the left-hand-side mudguard.

Jaguar says the official combined average consumption is 23kWh/100km. Our car’s trip computer showed we averaged 24.2kWh/100km.

The WLTP range is 408km, or 446km under the more-lenient NEDC regime. Fully charged, our vehicle indicated 407km of range in normal mode and 415km in 'Eco' mode.

After 345km, our distance-to-empty read 14km, meaning we averaged a very reasonable 359km under absolutely normal urban conditions, with some freeway driving thrown in.

Using a 150kW DC fast charger, we added 200km of range in exactly 30 minutes. It cost us around $31.

For the record, AC charging from empty to full using a regular household socket will take nearly 44 hours, or 13.5hr and just 9.25hr if you have access to a 7kW or 11kW Wallbox, respectively.

Meanwhile, a 50kW DC fast charger needs 75 minutes to go from 10-80 per cent full, or 45 minutes with anything above a 105kW charger, as that’s the Jaguar’s maximum capacity.

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.

One of the great EV questions is just how premium brands like Jaguar, BMW and Mercedes-Benz can justify their higher prices, when comparatively inexpensive alternatives from BYD, Hyundai and Kia rely on similar electric motor tech.

Indeed, a Tesla Model Y Performance offers the same acceleration and a higher top speed at nearly $100K under our EV400 HSE as tested.

But then you snuggle into that opulent cabin, buckle up, and realise that – just as the original XJ changed big luxury sedans forever back in ’68 with its sophistication and lush ride – the I-Pace still sets the tone for luxury EV SUVs.

Push the D button and – even in 'Comfort' mode – the Jaguar steps off the line briskly. A long-travel accelerator pedal tune disguises the fact that the EV400 is actually sensationally fast, as it swiftly yet silently streaks towards triple digits in no time at all, accompanied by a dull turbine-like drone.

Select 'Dynamic' mode, and the I-Pace’s performance lives up to both the make and model names, offering instant, pinned-back-in-your-seat thrust as well as ample muscle as it glides along.

Flex your right foot and you're already tailgating Mercedes AMG and BMW M-Sport SUVs in no time. Immediate, addictive speed.

A low centre of gravity; that double wishbone and multi-link suspension layout; near 50/50 weight distribution – we’re expecting something special here, and happily, the I-Pace as optioned up with air suspension, adaptive dampers and 22-inch wheels refuses to disappoint.

The sheer urgency from the twin electric motors is matched by reassuring grip and control, even over the rain-soaked hills we belted along.

Beautifully weighted steering, offering lots of road connection, adds to the sense of confidence and calm, as the Jaguar handles corners with a flat, contained composure.

It’s only when you’re really fanging it through tight and twisty turns that this EV SUV starts to feel its considerable mass.

Keep in mind that our HSE included the optional air suspension and adaptive dampers, because together they provide impressive suppleness and sweet isolation (in Comfort mode, obviously) to go with the I-Pace’s unassuming agility.

They allow for those oversized alloys to swell out the arches without resulting in a ruinous ride – something you’d get a taste of if you switch to Dynamic mode, where everything stiffens up noticeably.

Thus specified, we’d imagine the softness would be well off the scale on the standard 20-inch rubber.  

As tested, our HSE is one of the most enjoyable luxury SUVs to drive and travel in at speed, regardless of what sort of fuel you’re using.

Downsides? Around town, the limited side and rear vision mixed with the Jaguar’s two-metre width makes manoeuvring a little daunting at times.

The turning circle is on the larger side. And the traffic sign recognition tech is far from reliable and doesn’t work in concert with the adaptive cruise control so can’t automatically alter speed to what’s signposted.

Yet our biggest gripe is the lack of greater single-pedal braking when lifting off the throttle.

A set of paddles to alter the regeneration braking force as per Hyundai’s set-up would be appreciated.

This is one of the single biggest giveaways to the Jaguar’s advancing years.

Still, as a hushed, refined, comfortable and forcefully quick luxury EV SUV experience, the I-Pace, with the choice options as fitted, remains a fierce opponent against newer alternatives. Especially from behind the wheel.

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 I-Pace is covered by an industry-average five-year/unlimited kilometre warranty, along with five years of roadside assistance.

Additionally, owners will enjoy five years/130,000km of free scheduled servicing. These are at 12 months or 26,000km.

Jaguar says the EV traction battery is covered by an eight-year/160,000km warranty, with a minimum of 70 per cent state of health.

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.
