Leapmotor B10 vs Lexus RX350

What's the difference?

I’ll be a shame if the B10 doesn’t sell well, because it doesn’t suffer from many of the downfalls of its compatriots and its price is extremely competitive for what you get.

As a comfortable smallish SUV, it meets par, and it’s on the better side of tech when it comes to cars from China, and it doesn’t have any major on-road red flags.

You really wouldn’t be disappointed with this having paid $40K, just skip the base model and go for the Design.

The RX is a big SUV that doesn't always look, or drive, like one, and – in 500h guise especially – can put a smile on a driver's face, too.

Gone are the cabin quirks and the polarising design elements (well, mostly...), and in their place you'll find a solid, premium-feeling family offering without much in the way of drawbacks.

Right after we praise the B10 for its value, we need to talk about its looks. A slight drop in tone as the second Leapmotor to land in Australia looks an awful lot like the first, and it’s relatively bland.

It’s not ugly, but it’s not particularly inspiring and there’s not much character to this little electric SUV.

It’s got a very upright silhouette at the front with a slightly sloping roofline at the rear, so the overall shape is appealing, but the lack of distinct features makes the B10 an anonymous commuter for now, especially with its similarities to the C10.

You can tell them apart by the C10’s slightly larger size if they’re near each other, or the B10’s more in-line headlight bar, where the C10’s have a ‘droop’ at the sides.

The large section of black at the lower half of the front is also unappealing, though darker colours like the optional 'Starry Night Blue' or 'Dawn Purple' (both $990) blend into it better than standard 'Light White'.

To its credit, at least the B10 doesn’t fall victim to the design crutch of adding trim and plastic for no reason.

In terms of the specifics, the B10 is 4515mm long, 1885mm wide and 1665mm tall with a 2735mm wheelbase, making it quite the large small SUV.

Inside, the cabin looks and feels roomy thanks to the test car’s light interior, decent windows and the light from the sunroof, as well as the fact the EV powertrains are compact and generally don’t interfere with cabin space.

Materials aren’t all scratchy hard plastic, though it is dotted around, and the general look of the B10 inside feels more premium than its price would have you thinking, despite the simplicity of the layout and design.

Honestly, the Lexus RX looks far more powerful, and cohesive, in the metal than it does in some photos, and in the right colour (we're fond on the deep black or the copper-rose hues), it looks downright fetching.

That Predator-shaped front-end is massive, but the way the Spindle grille kind of bleeds in the body work at the nose of the vehicle is a neat trick, and the whole design ethos gives the RX a sportier, more modern, and more intimidating, energy from almost every angle.

Perhaps the most clever element though is the wave-like design piece that links the rear window with the boot, somehow managing to shrink almost-five-metre SUV (visually, at least), and leaving the RX looking more sporty than hulking.

The door handles are cool, too. They’re fixed, and you just touch them to open the door, with a similar system used once inside to get out again.

Inside, Lexus has gone for a clean, modern-feeling space, and, thankfully, there isn't a Remote Touch trackpad in sight. Instead, you can choose between two screen sizes – 9.8- or 14.0-inch – which kind of dominate the dash, while the air-con controls are digital and interactive, too.

It must be said, though, some interior treatments feel far more special than others, and while Lexus in Australia isn't spilling on specifics for our market just yet, the top-spec models will almost certainly feel more plush than the cheaper ones.

Getting into the B10 requires a minor annoyance - unlocking and locking the car requires a keycard to be tapped on the drivers’ side mirror like you're scanning to access your floor in a hotel elevator.

There’s an app that adds a fair bit of functionality, but having to whip your phone out ahead of jumping in the car is also irritating.

Once you’re in, though, the space inside the B10 is well laid-out, even if much of its functionality is crammed into the big central touchscreen - it’s always ‘points off’ for a lack of physical buttons in this section of a review.

Once you’re used to it and have sorted out your personal settings on the multimedia software, it becomes more natural and less distracting, though Apple CarPlay and Android Auto would occasionally lag in the car on test.

The good news is they now exist for the brand in the B10, with the Leapmotor C10 still lacking the vital in-car mirroring tech.

The ergonomics and interior space work well, generally, with comfortable pews and good vision, plus decent spaces to keep things out of the way. The phone charger being in a very visible and accessible position might tempt some naughty screen-keen drivers, and being in the sun without a vent for cooling while charging means your phone will get proper hot.

The second row is extremely spacious, belying the fact this car is classified as a small SUV. Oodles of legroom and enough headroom for a tall adult means the B10 outguns rivals in terms of good options for parents (note the B10’s extremely strong 95 per cent child safety score from ANCAP, too) or anyone who needs to cart humans around regularly.

Behind the second row is a 490L boot, which becomes 1475L when the second row is folded down.

There’s space under the floor for cables and messy bits, but unfortunately no spare wheel, just a tyre repair kit, so more points off for that.

The entire RX range now rides on Lexus' GA-K platform, which is lighter (-40kg), more rigid, and offers a lower centre of gravity (-15mm) than the model it replaces.

The RX is wider (+25mm to 1920mm), lower (-10mm to 1695mm), but no longer (still 4890mm) than the outgoing model. But Lexus has lengthened the wheelbase (+60mm to 2850mm) to earn some extra backseat space for rear riders.

And it must be said, there is lots of room for backseat riders. Sitting behind my own 175cm driving position I had more than enough knee room, and enough head room, and a general feeling of airy spaciousness.

Elsewhere you get the usual practicality perks, with two cupholders up front, two more in the pull-down seat divider that splits the rear seat, and there are two ISOFIX attachment points in the back seat, too.

Charging is handled by a four USB ports, and depending on the trim/spec balance Lexus in Australia shoots for, you should at least find vents with temp controls for backseat riders, too.

Lexus is yet to confirm the luggage space specs for the new RX, but given it’s only being offered with five seats, and that there’s been no change to the vehicle’s length, you can expect a fair bit of room for bags in its auto-opening boot.

This is an arbitrary seven out of 10, here. Because we don't yet know how many trim levels the new RX will launch in, how much each will cost, or what you'll get for your investment.

What we do know is that the RX will launch with three powertrain options: an all-new turbocharged hybrid, a second, more conventional hybrid, and a turbo-petrol engine. There’s a plug-in hybrid version available overseas, but we ain’t getting it. Or at least, not yet.

In terms of specific trims and equipment levels, you’ll need to wait until closer to the RX’s launch in early 2023 for the full skinny. But you can expect a choice between a 9.8-inch or 14.0-inch central touchscreen with wireless Apple CarPlay and Android Auto, an eLatch door system with fixed handles that unlatch at the push of button inside and out, as well as more high-tech safety kit (thanks to Lexus Safety System 3.0) than you can shake a radar at.

There’s only one powertrain option for the Leapmotor B10, a single, rear-mounted electric motor that produces 160kW and 240Nm, which makes the electric SUV good for a claimed 0-100km/h time of 8.0 seconds in both variants.

Top speed is a claimed 170km/h, also regardless of the variant.

Let’s start with what we’re not getting at launch. Internationally, there's a new plug-in hybrid variant that pairs a 227kW hybrid system with a 18.1kWh lithium-ion battery for an EV driving range of more than 65kms, but fight though Lexus in Australia did, it couldn't secure the model for our market at launch. It wants it though, and badly. So watch this space. 

Instead we get three options, including the RX 350h, which pairs a 2.5-litre petrol engine with Lexus' existing hybrid system to produce a total 180kW and 316Nm. It's paired with a constantly variable transmission and will be offered in two- or all-wheel drive.

There’s also a turbocharged 2.4-litre petrol engine on offer in the RX 350, good for 205kW and 430Nm, and paired with an eight speed automatic and AWD.

But the powertrain I really, really like lives in the RX 500h F Performance, and pairs a 2.4-litre turbocharged petrol engine with an electric motor up front, and a second at the rear axle, for a total of 273kW and 551Nm.

The all-new hybrid system has been designed with turbocharged engines in mind, and features a single electric motor at the front, and a bigger rear motor, with the latter able to provide real driving power to the rear tyres - and contribute to a sprint to 100km/h of just 5.9secs.

Lexus calls it an 'eAxle' motor, and it can deliver some 76kW to the rear tyres. It pairs with a 'DIRECT4' all-wheel drive system which the brand says improves "handling, controllability, and feel."

Fitting, then, that it features on the RX 500h F Performance, which also introduces a new go-fast tier for the Lexus brand (though one you can expect to see more frequently in the near future), and which sits between the existing F Sport and the top-tier, full-fat F models.

The brand says things like bigger brakes, performance components and the highest power outputs will be reserved for the F Performance models. And so it is with the RX 500h F Performance, which welcomes six-piston front brakes, adaptive variable suspension, dynamic rear steering and 21-inch wheels.

Leapmotor claims the B10 will, from its LFP battery of either 56.2kWh for the Style or 67.1kWh for the Design LR, draw 17.2kWh/100km or 17.3kWh/100km, respectively under WLTP testing.

The result is the Style offering up a 361km WLTP-tested driving range, and the Design LR a more useful 434km.

While we were unable to properly confirm this claim on the launch, the trip computer after a mix of highway driving and more spirited back-road testing displayed a figure of 13.5kWh/100km, while the previous 1447km of driving had reportedly measured in at 14.7kWh.

Charging from 30 to 80 per cent takes approximately 20 minutes regardless of spec and battery size. The smaller battery can be charged via DC fast-charging at a maximum 140kW, and the larger at 168kW. Both max out at 11kW under AC charging.

Let’s start with the pure-petrol RX 350, which will sip a claimed 8.8 litres per hundred kilometres on the combined cycle, and will demand premium petrol. The RX 350h is more fuel efficient, demanding 6.4 to 6.7 litres per hundred kilometres on the combined cycle.

But the most impressive is the RX 500h, which Lexus says will need 8.2 to 8.5 litres per hundred kilometres — making it more efficient than the petrol-powered RX 350, despite producing an extra 68 kilowatts of power and 121 newton metres of torque.

The Leapmotor B10 was developed with testing at Stellantis’ European proving ground in Italy. This is because despite Leapmotor being its own brand within China, its international operations are a joint-venture between itself and Stellantis.

There are some on-paper shreds of evidence for this, a rear-wheel drive layout and a claimed 50/50 weight distribution help, but get the B10 on the road and it’s clear this isn’t a car that’s relying entirely on price, a long list of features and some showroom shine to sell.

After the initial familiarisation that comes with many new electric cars, particularly from China, the Leapmotor B10 becomes easy to settle into a rhythm with, especially if you turn off some of its more intrusive ADAS features like lane-keep, driver monitoring and speed limit warning. The latter can sometimes get a limit wrong, and though the B10’s chimes aren’t audibly overbearing, they are persistent.

While the B10 doesn’t excel in any areas on the road, it doesn’t fall down significantly in any either.

Its suspension soaks up bumps relatively well, and despite some vibrations on rougher roads the B10 is pretty comfortable. The tyres it rides on as standard, however, are rather noisy, so if there’s an opportunity to swap out the Linglong defaults to something better, we’d advise it.

The tyres also squeal rather quickly when cornering, not necessarily because the B10 is about to let go, but just because the weight of the car appears to be pushing on the front outside tyre in cornering.

The B10 holds up better than\ a family car really needs to in dynamic driving, but we wouldn’t be doing mountain runs or track days in one. 

There’s a little body roll in corners, but not nearly as much as has been in other models riding on the apparently soft suspension preferred in China.

The steering, braking and acceleration all have a mild vagueness to them, but once you’re honed in they’re all predictable. The steering can be adjusted for weight, and its lightest setting is too light, while the acceleration feels lethargic in its lowest setting and too aggressive in its highest.

There’s not a lot of regenerative braking strength, but it’s enough to help regulate speed once you’re used to how mildly it comes in - again, depending on your preferences and settings.

The good news here is that the B10 is easy to drive, and only very serious road bumps on fast corners unsettled it on test - the kind you’d expect to upset any car.

Right, let’s cut to the chase here. I like the way the all-new RX family drives, pretty much across the board. If that’s all the information you want or need, feel free to check out here and move on to the next sub-heading.

Still here? Ok, then let’s go a little deeper.

None of the powertrains on offer feel under-powered in the RX range, which is a good start, but they all do their jobs a little differently. 

The RX 350 is probably the most familiar, with a traditional automatic and that well-known petrol-powered punch. It’s not the most powerful engine on offer here, but it’s more than enough to get the RX up and moving — but, for mine, it can feel a little thrashy (or like it’s straining a little too hard), when you really start to push it, but such is the price you pay for a four-cylinder engine pushing a large SUV.

Next up is the RX 350h, which Lexus reckons will be the best-selling model in Australia. Lexus and Toyota have been doing hybrid powertrains for some time now, and the system fitted to the new RX is predictably solid-feeling, though it too has its drawbacks – namely that the constantly variable transmission can drone on and on under constant acceleration, and even the commendably insulated cabin can’t block it out completely.

So if this is a Goldilocks’ scenario, then the just right has to be the RX 500h, which blends its powerful powertrain with a traditional-feeling automatic to deliver plenty of performance and a tight, engaging drive experience that makes it feel as though the big SUV is somehow shrinking around you from behind the wheel, courtesy of the best performance kit (brakes, adaptive suspension, etc).

But to be honest, no matter the RX, the thing that really stands out here is its on-road dynamics. The car doesn’t really wobble about, there’s not much in the way of body roll, and it feels tight and confidence inspiring, no matter the model - but especially the rear-wheel-steering equipped 500h.

The RX also does a commendable job of locking the outside world outside of the cabin. Where you want it to be a calm and sedate family hauler, it can be that. But it can also put a smile on your face on the right road, too.

And that, I think, is something to be celebrated. And also not something we’ve come to associate with Lexus over the years. But that’s now beginning to change. Long live F Sport Performance, then.

The Lexus RX welcomes the brand's Lexus Safety System 3.0 setup, which means more high-tech kit than you can shake a radar at.

What appears where on the Australian lineup remains to be seen, but internationally the RX will offer things like Advanced Park, remote parking from your smart phone, Safe Exit Assist that will actually prevent you opening the doors should the cameras detect pedestrians or cyclists, and Pre-Crash Safety, which scans intersections for bikes, people or cars, and activate alarms and the brakes should it sense a collision.

That, and things like Front Cross-Traffic Alert, active cruise, Lane Departure Warning and Lane Tracing Assist, road-sign recognition and Lane Change Assist, should see Lexus shooting for a five-star ANCAP safety rating.

The B10’s post-purchase prospects are generally solid, though Leapmotor’s six-year, 160,000km warranty is an area where it falls short of rivals which are offering longer, unlimited kilometre warranties.

The battery is covered for eight years or 180,000km, whichever comes first, which is pretty par for an EV.

Servicing is capped-price for the first eight years, with each service costing $370 on average. The eight-year span makes it pretty appealing, per 12-month interval or every 20,000km.

There are currently 20 dealers across the country, though more are coming, while Leapmotor also offers eight years of roadside service.

The Lexus family is covered by a five-year, unlimited-kilometre warranty, which is about bang-on in the premium-vehicle space. 

While servicing details are yet to be confirmed, the previous RX required a trip to the service centre every 12 months or 15,000kms, and it will fall under the brand’s capped-price servicing program, and the Lexus Encore program, which offers all sorts of perks to owners.
