Honda Jazz vs Lexus Rx450H+

What's the difference?

The Honda Jazz is an extremely capable small car, with an ace card of virtually unbeatable interior space. While it's hardly an excitement machine, or the best looking or equipped in its class (it is missing out on some useful safety gear), the Jazz deserves its status as a well-loved hatchback.

The best in the range is probably the VTi. There isn't anything compelling further up the variants unless you're keen on bigger wheels or leather trim. Its entry-level offering is a good-value, sturdy car that is packed with its best qualities, no matter which one you buy.

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 Jazz's exterior design is instantly recognisable. The shape has been roughly the same since the car's 2002 debut, with the mildest evolution over the years. The 2018 Jazz leads with the chin a bit, with a pronounced underbite and when fitted with a chrome grille, it looks a bit like the giant Jaws from James Bond after whacking his head.

Apart from that, the slimmed headlights and one-box body shape are almost entirely inoffensive, save for the chunky, stacked rear lights.

When you head inside it's a simple, basic interior. Well put together, it's easy to find your way around and, because there isn't much happening in here, it's unlikely you'll need the owner's manual, unless you want to identify and use every single deployment of the excellent Magic Seats in the back.

As you climb the range, you'll start to see body-kit additions like a rear spoiler and side skirts, but nothing particularly racy.

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 interior is full of cleverness packed into a small space. The centre console has two cup holders, a space for your phone and a compartmentalised open tray reachable by both front and rear-seat passengers. A third cupholder folds out of the dash on the driver's side. The back seat doesn't have any cupholders, unfortunately, and nor is there a centre armrest.

Rear legroom is impressive for such a small car - it's no wonder the HR-V compact SUV was spun off the Jazz platform. Added to that are the excellent 'Magic Seats', which fold in a variety of ways to increase the boot space dimensions from 354 litres to 1314 litres.

Luggage capacity is not bad for such a small car and with the flexible interior, the boot size goes up by four times in volume. This is one area in which it really does outdo the  Mazda2. The removable cargo cover means you can get a decent chest of drawers in, however there's a bit of a drop once you get things over the loading lip.

You can also fold the seat bases up and out of the way to provide space for shrubbery, or a dog, or an awkward flat pack. 

The basic VTi misses out on a bit of storage, namely the centre console storage box and driver's side seatback pocket, but the rest of the range has them both.

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.

All Jazzes are powered by Honda's 1.5-litre single-cam four-cylinder. The engine specs don't make for inspiring reading, with just 88kW and 145Nm. That's not a lot of horsepower, but when you consider the weight of the car, the figures don't look so weedy.

Power goes to the front wheels, so the Jazz is definitely not an off-road proposition.

Only the base model VTi has a choice of manual vs automatic, with a five-speed manual transmission and a CVT auto to choose from.

As to the question of timing belt or chain, the Jazz has the latter, so you don't have to worry about a belt change. The oil type is 5W-30

There is no diesel option, so there'll be no diesel vs petrol argument. Nor is there an EV or plug-in hybrid - with a battery, it's unlikely you'd have much boot space left. There isn't an LPG, 4x4, or AWD version either.

If you can be bothered fitting a towbar, the manual's towing capacity is 1000kg braked while the CVT's load capacity drops to 850kg. Both transmissions will haul 450kg unbraked.

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.

Fuel figures are slightly different, depending on the gearbox you've chosen. Honda claims you'll get 6.5L/100km on the combined cycle in a manual while the CVT uses a bit less, coming in at 5.9L/100km. So fuel consumption km/L works out at about 15km/L for the five speed and 17.km/L in the CVT.

Real-world consumption is a little different, however. Our most recent test with the manual yielded 8.0L/100km while the CVT chugged down 8.2L/100km. Having said that, you'll see better fuel economy figures in the manual if, as I admitted in my VTi review, you don't drive it enthusiastically. The CVT was a bit disappointing because I was a lot more sedate in that one and it didn't deliver better mileage than the manual.

Fuel-tank capacity is 40 litres.

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 Jazz has always been a comfortable, easygoing car with performance figures to match. Its 0-100km/h acceleration is best described as leisurely, so if it's speed your after, this car isn't for you.

That said, the manual VTi is terrific fun to drive. Switch to the CVT, however, and the Jazz's reputation is restored. A good ride for front-seat passengers comes from McPherson struts up front while the rear suspension is by torsion beams, meaning rear-seat occupants can get a few shocks over bumps.

Road noise is a little higher than you might expect, but that's probably a combination of tyres and a commitment to lightness.

Obviously, being such a small car, manouverability is a key advantage. The turning radius is 5.2m, which is good but not super tight and the light, electric power steering makes dodging about easy. It certainly doesn't feel like it's on rails, but that's hardly what a car with a such a small engine size is about.

Ground clearance is 137mm, which is reasonable but jumping gutters is not advised.

In the base manual, you have a five-speed with a light clutch and an easy shift. For a motor missing out on a second cam, let alone a turbo, progress is swift rather than exciting, the engine droning away with a relaxed air. The CVT has an eco mode, which further blunts performance, but a ring of light around speedo glows green if you're behaving yourself.

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.

Honda's standard five year/unlimited kilometre warranty also comes with capped-price servicing for the first five years or 10 services, whichever comes first. Service intervals are every 10,000km or six months. 

Up to 30,000km you won't have any extras but once you hit 40,000km you'll have to do the brake fluid, which is a reaonable $144 extra. Your service cost structure is otherwise simple - $259 for odd numbers and $297 for even.

Many people ask where the Honda Jazz is built, and the answer to that is "not Japan", or in Honda's Thailand plant.

Second-hand values appear strong, with around 60 percent of value retained after three years. Resale value is something of a Honda strength, which is probably to do with a lack of high-profile reliability issues.

A dip into the usual internet forums yields little in the way of common faults, problems, complaints or issues for the Jazz. Some look for automatic transmission problems, others for manual gearbox problems, but the current Jazz seems quite clear of defects in Australian-delivered cars.

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.
