Leapmotor B03X review

Exterior & design of the 2027 Leapmotor B03X

• Smooth and inoffensive exterior design
• Roof rails and 18-inch alloy wheels
• Large dimensions for this class

The front of the Leapmotor B03X is, as we've come to expect from the company, notably smooth and curvy. That's not to say it's without interest, partly due to the sharp, high-set bonnet line joining the headlights.

Leapmotor's three-bar LED daytime running light graphic helps define the "face" of the B03X, and the brand's name is stamped into the dark plastic air intake section under the numberplate holder. On either side are stylised "air curtains" to channel airflow.

Viewed from the side, the Leapmotor B03X could be from any number of carmakers, though it's far from ugly. Neatly integrated door handles and a generous amount of glass help it look larger than it is, giving the B03X presence.

This is enhanced by the tall roof and black cladding around the wheelarches, giving the impression of a car with high ground clearance.

The shape of the side glass is livened up by the thick black C-pillar, lending a floating effect to the roof. Roof rails cement the SUV image.

At the back, smooth bodywork remains the order of the day, and it would be fairly featureless were it not for the Leapmotor wordmark emblazoned across the tailgate.

That said, take a closer look at the rear lights and you might think they appear like two smiling cartoon frogs. The 18-inch alloy wheels have a smart design, too.

Interior, practicality, tech & comfort of the 2027 Leapmotor B03X

• Versatile rear-seat arrangement
• Huge boot for a compact crossover
• Too many functions rely on touchscreen

Though built to a low price, the Leapmotor B03X's cabin is a high point, mixing decent quality and equipment with a lot of space, useful versatility and a massive boot. Leapmotor has even let its designers have a bit of fun by incorporating a cartoon character motif throughout. It's a shame the car relies so heavily on its touchscreen, though.

Getting comfortable in the driver's seat

There isn't much of a sill to get over when getting into the driver's seat. In Design specification, both front seats feature six-way electric adjustment, but the steering wheel is manually adjustable for reach and rake - though not over an especially broad range. It's not possible to adjust the front seatbelt height on the B-pillar, unfortunately.

Both Life and Design trims get an synthetic-leather steering wheel with a two-spoke design that is slightly flat at the bottom. It features a combination of buttons and scroll wheels to perform various tasks.

Outward visibility is generally good, thanks in part to the raised seating position and A-pillars that don't obstruct a great deal. The door mirrors are a decent size, while the view to the rear is slightly limited by a window that isn't as wide as it looks from the outside.

For added comfort in winter, a heated steering wheel is standard on Design, as are heated front seats. That specification also includes a choice of Currant Black or lighter Oat Grey synthetic leather upholstery.

Infotainment and technology

In front of the driver is an 8.8-inch digital cluster and in the middle of the B03X is a large touchscreen, measuring 14.6 inches across the diagonal. It's not a bad system, but we'd prefer more physical switchgear.

Using Leapmotor's own Leap OS 4.0 Plus, there's online navigation, real-time traffic updates, trip-planning functionality and over-the-air updates included, though many owners will likely pair their phone and use either Apple CarPlay or Android Auto.

There is a separate Leapmotor app for smartphones that allows owners to pre-heat or cool the car, pre-condition the battery, schedule charging and more.

Practicality around the cabin

Leapmotor makes a point of highlighting how practical the B03X's interior is, citing 33 storage compartments in all. Long door bins up front are wide enough to fit a couple of small drink bottles, and beneath the centre console is a reasonable storage area large enough to fit a small bag or other oddments.

On top of the centre console is a wireless charging pad and two cupholders. The central armrest lifts to access a storage bin, though this isn't especially deep. Two USB-C ports are located inside the armrest bin.

Rear-seat passenger space

One of the B03X's strong suits is how much rear passenger space is available. The floor is flat all the way across the rear of the cabin, and when seated in the outer seats there is just enough room to get your feet underneath the front seats if you want to stretch out a little more.

The door bins in the rear aren't as large as those in the front, but they remain useful for holding a drink bottle. Surprisingly, there are no pockets on the backs of the front seats, which is a strange omission given how useful they can be.

Leapmotor redeems itself with some cleverly designed flip-up rear seats. A large handle on the side of either rear seat releases the base, which tilts upwards and locks in place.

This provides some very welcome additional storage in the rear and is a setup similar to Honda's "Magic Seats" design, though the Leapmotor's seat bases are still quite chunky and don't fold into an entirely vertical position.

There are no separate air vents in the rear of the cabin, but there are one USB-A and one USB-C charging port on the rear of the centre console.

Fitting child seats to the Leapmotor B03X

Access to the rear seats isn't bad thanks to the door openings and the angle they open to, so getting child seats in and out of the B03X's rear shouldn't be too much of a chore. Both outer rear seats are equipped with ISOFIX anchoring points. The centre seat is too narrow for a child seat and there are no ISOFIX points in the front passenger seat.

Boot space in the Leapmotor B03X

Lifting the tailgate reveals a boot aperture that isn't as wide as you might expect from the exterior design. Still, there is an almost flat load floor and 510 litres of boot space available in total.

We found the tonneau cover very flimsy and cheap, but we did like how the boot floor can be set to a high or a low position.

An underfloor storage area is easily accessible by lifting the boot floor, and two small notches can hold that in place, leaving your hands free. This area provides 105 litres of the 510-litre total and is made from durable plastic that can easily be washed out, as it has a drain hole in the bottom. That makes it very useful for keeping muddy clothing or sports equipment separate from the main luggage.

The rear seats have a 60:40 split and, when folded, the total cargo capacity rises to 1,605 litres. There is no frunk storage space up front.

Towing with the Leapmotor B03X

The Leapmotor B03X is not rated for towing.

Safety in the Leapmotor B03X

The B03X has not yet been assessed by Euro NCAP for safety, but we would expect it to score highly given how other recent Leapmotor models have performed. There are 21 driver-assistance systems in the Leapmotor B03X, including those designed to check driver attentiveness, reduce driver workload and mitigate collisions.

A network of 14 sensors and cameras continually monitors the area surrounding the car, supporting the driver-assistance systems. There are seven airbags.

Performance of the 2027 Leapmotor B03X

• Two different powertrains
• Front-wheel drive across the range
• Poor traction even in dry conditions

All versions of the B03X use a front-wheel-drive setup. The 39.8kWh battery is paired with a 176hp motor producing 200Nm and a single-speed automatic transmission. With the 53kWh battery, motor output increases to 197hp while torque remains at 200Nm.

Driving the Leapmotor B03X in Spain

Words by Dave Humphreys on 12 September 2026

The hot September weather on the southern coast of Spain was good news for the Leapmotor's 53kWh battery and proved a test for the B03X's air conditioning, which we're pleased to report blows nice and cold when needed.

We began our drive by leaving the busy roads of Malaga and heading out into the hilly countryside, where we had an opportunity to stretch the legs of Leapmotor's latest creation.

The B03X sits up on suspension that is on the firm side in an attempt to mitigate excessive body lean in the bends, and it manages to do that quite well. However, the firm setup also makes itself felt during vertical movements, resulting in a ride that could benefit a great deal from being softer.

There's no fancy adaptive air suspension here, just a passive setup comprising MacPherson struts up front and a torsion-beam rear axle. The latter can thump over sharper vertical impacts a bit when you're pressing on, though the relatively long wheelbase means the B03X feels stable in the bends.

While you can't alter the suspension settings, you can play around with the drive modes, which affect power delivery, steering weighting and the strength of the energy recuperation across three settings.

At its sportiest setting, the electric motor's torque overwhelms the front tyres surprisingly easily given the relatively low outputs. Part of that may be down to the Yokohama tyres fitted to our car, which didn't leave an overly positive impression.

You do need to delve into the touchscreen menu system to change the driving settings, and in reality, we reckon the energy recuperation is the only one that warrants regular adjustment by the driver. It's a pity, then, that Leapmotor has not provided more physical switchgear inside, to the detriment of the driving experience.

In its highest or strongest setting, the one-pedal feel is good and well suited to driving in stop-start traffic, whereas the mid-level setting works well at bleeding off some speed on more fluid roads. At higher speeds, there's a touch of wind whistle around the door mirrors and some road noise as well.

The only major aspect that takes away from the driving experience is the over-eager driver-assistance system, which provides a seemingly never-ending cacophony of beeps and chimes of varying tones, often for the most minor of things. These can be muted, but if you want to keep them that way you'll need to set up a driver profile and select it for each journey.

Range, battery, charging and running costs of the 2027 Leapmotor B03X

• Choice of two battery sizes
• Up to 382km of official range
• DC charging at up to 133kW

Leapmotor keeps things simple for the B03X. It comprises two battery sizes, both of which use LFP chemistry, and each is paired with a specific motor driving the front wheels. There isn't a great deal of difference between the power outputs of the two motors, making the choice more about which battery size you prefer - or can afford. The official ranges offered by both are broadly on par with the segment, as is the charging capability.

Battery options and official range

Leapmotor exclusively uses lithium-iron-phosphate chemistry for the batteries in the B03X. Its 'CTC2.0 Plus' design is a cell-to-chassis short-cell battery system that directly integrates the battery into the vehicle's structure. Doing so improves torsional rigidity, lowers the car's centre of gravity, boosts interior space and enhances safety.

The 39.8kWh pack provides a WLTP range of 292 kilometres, while the 53kWh battery increases that to 382 kilometres.

Real-world range and efficiency of the Leapmotor B03X

According to official figures, the combined energy consumption of the Leapmotor B03X is 15.7kWh/100km, which is respectable enough for a car of this size. During our time with the car, we saw consumption figures that were both better and worse than that depending on conditions.

When our route took in more mountainous driving, consumption rose to just over 20kWh/100km, but more impressive was the urban driving, where the figure dropped significantly to 11.5kWh/100km.

Our drive was during quite warm weather that would suit the battery, though it did also mean we had the air conditioning running to keep the cabin cool. Leapmotor fits a heat pump as standard to the B03X Design, which should help with efficiency in the winter.

Charging up the Leapmotor B03X

As standard, the Leapmotor B03X gets 11kW charging on AC, while peak DC-charging power is 100kW for the 39.8kWh battery and 133kW for the 53kWh battery. The charging port is located on the front left wing of the car.

Servicing the Leapmotor B03X

The Leapmotor B03X has a service schedule of once per year or every 20,000 kilometres.

Leapmotor B03X warranty

All Leapmotor cars sold new in Ireland come with a six-year, unlimited-mileage warranty. The high-voltage battery is covered for eight years or 160,000 kilometres.

Irish pricing & rivals to the 2027 Leapmotor B03X

• Irish pricing has yet to be announced
• Expected to start at around €25,000
• Choice of two trim levels

We don't yet have pricing for the B03X in Ireland, though we expect it to be one of the more competitively priced cars in its segment when it goes on sale.

The small 39.8kWh battery should help keep the entry price low, though Leapmotor expects 90 per cent of sales to be of the 53kWh version.

There will be two trim levels to choose from: Life and Design. While the exact details of the Life specification are being finalised, we do know that it will have the 8.8-inch and 14.6-inch displays inside and feature black fabric upholstery and a synthetic leather steering wheel.

Standard equipment on the Design trim includes synthetic leather upholstery, voice control, remote app access, electrically adjustable and heated front seats, a heated steering wheel, automatic air conditioning, a heat pump, auto wipers, the flexible rear seats and 360-degree camera system with parking sensors.

Verdict - should you buy the 2027 Leapmotor B03X?

The B03X doesn't drive with the same finesse as some of its direct competitors. The suspension is a touch on the firm side, and while performance isn't lacking, its delivery could be more polished at times. The same is true of the driver-assistance systems.

Those aspects aside, the Leapmotor comes well-equipped in Design specification and offers plenty of space inside with some practical features. Pricing will play a key role in how desirable it is to buyers seeking value for money.
