Everything You Should Know About Leapmotor B03 Specifications

Leapmotor has unveiled the all-new B03, an all-electric supermini developed to combine urban practicality, flexible interior packaging and modern vehicle technology. With a claimed WLTP range of up to 242 miles, a 194 hp electric motor and DC rapid charging from 10% to 80% in approximately 21 minutes, the hatchback is designed to accommodate both daily commuting and longer journeys.

The B03 is the second model based on Leapmotor’s Compact Electric Platform, following the B03X crossover. It uses the company’s Cell-to-Chassis 2.0 Plus architecture and LEAP3.5 technology platform, with a digital-focused cabin, a comprehensive driver assistance package and adaptable cargo space.

For the UK market, Leapmotor plans to offer the B03 in a single, well-equipped trim level. Pricing and final market specifications have yet to be confirmed.

Leapmotor B03 Price and Available Version

Leapmotor has outlined a simplified UK range built around one generously equipped configuration. This approach is intended to make the purchasing process more straightforward by including a broad selection of comfort, connectivity and safety features as standard.

The B03’s final competitiveness will depend on its UK pricing, equipment availability and warranty package once sales details are released.

Exterior Dimensions and Urban-Friendly Design

The Leapmotor B03 measures 4,175 mm long, 1,790 mm wide and 1,550 mm tall, with a wheelbase of 2,605 mm. Its relatively compact footprint is intended to make the car manageable on narrow streets and in urban parking spaces while preserving useful passenger and luggage room.

Exterior styling features flowing body surfaces, a contrasting two-tone roof, slim three-segment LED headlights and distinctive rear lighting. Short overhangs contribute to its proportions, while a turning circle of 9.8 metres is designed to improve manoeuvrability in confined areas.

The design combines the proportions of a small hatchback with details intended to give the B03 a more contemporary appearance than a conventional city car.

Digital Cockpit and Interior Features

Inside, the B03 adopts a minimalist dashboard layout built around two digital displays. A 14.6-inch central infotainment touchscreen is paired with an 8.8-inch digital instrument display, providing access to vehicle information, settings and compatible applications.

The system runs Leapmotor’s LEAP OS 4.0 Plus software, which includes a customisable interface, 3D graphics and support for displaying multiple applications.

The cabin also features soft-touch materials and selected OEKO-TEX-certified elements. Morse-code-inspired decorative details appear on certain interior surfaces, seat materials and speaker grilles. Small design elements inspired by Leapmotor’s mascot, Leapy, provide additional visual details.

Ambient lighting offers multiple colours and animation settings, including effects linked to music. It can also interact with selected vehicle alerts, such as parking sensor warnings and door-opening collision notifications.

An efficient heat pump is designed to reduce the energy required for cabin heating compared with conventional electric resistance heating. This can help limit the effect of heating demand on driving range during colder conditions, although actual energy savings will depend on the environment and usage.

Flexible Seating and Up to 1,305 Litres of Cargo Space

Interior versatility is a central feature of the Leapmotor B03. The manufacturer has incorporated 30 storage compartments throughout the cabin, alongside seating and loading arrangements designed to accommodate a range of everyday needs.

The front passenger seat can fold flat to make room for longer objects, while the driver’s seatback reclines by up to 149 degrees. The rear seat base, known as LeapFlex, can be flipped upwards to create an additional 578 mm of vertical loading space for taller items.

The rear seatbacks fold flat to expand the luggage compartment. Boot capacity is 405 litres with the rear seats in use, increasing to 1,305 litres when they are folded.

A dual-level cargo floor provides different arrangements for storage and loading height. With the rear seats folded and the floor in its upper position, the B03 can accommodate items up to 2.47 metres long. Lowering the floor creates additional underfloor storage, and a removable panel can be stowed away to maximise the available luggage area.

A separate 90-litre compartment beneath the boot floor, called the Leap Box, provides space for items that owners may prefer to keep apart from the main luggage compartment. Its easy-clean construction is intended to make it suitable for a variety of everyday uses.

These arrangements give the B03 flexibility for shopping, commuting, weekend travel and transporting bulky items without requiring a larger vehicle.

Electric Motor, Performance and Driving Modes

The Leapmotor B03 uses a front-mounted electric motor producing 145 kW, equivalent to 194 hp, and 200 Nm of torque. Power is delivered to the front wheels.

Leapmotor quotes a 0–62 mph acceleration time of 7.6 seconds and a maximum speed of 101 mph. The figures position the hatchback for everyday city driving as well as motorway use.

According to the manufacturer, the electric drive unit weighs 60 kg and incorporates an oil-cooling system to help manage motor temperatures during demanding operation. Its integrated design is intended to reduce weight and support efficiency.

Drivers can choose between Comfort, Standard and Sport modes. Comfort prioritises smoother acceleration and lighter steering, Standard aims to balance responsiveness and everyday usability, and Sport provides a more dynamic driving response.

The suspension combines MacPherson struts at the front with a torsion-beam arrangement at the rear. Leapmotor says the lightweight setup is designed to balance ride comfort, stability and steering precision while keeping vehicle complexity and weight under control.

53 kWh LFP Battery and 242-Mile WLTP Range

The B03 uses a 53 kWh lithium iron phosphate (LFP) battery, providing a claimed maximum WLTP driving range of 242 miles.

LFP battery chemistry is commonly used in electric vehicles because of its durability characteristics and suitability for frequent charging. The B03’s range figure, however, is a certified test-cycle claim rather than a guarantee of everyday driving distance.

Actual range will vary with speed, temperature, road conditions, driving style, passenger and luggage loads, and the use of heating or air conditioning.

For urban drivers, the combination of a compact body, front-wheel-drive layout and a range exceeding 200 miles on the WLTP cycle could make the B03 suitable for regular commuting and occasional longer trips.

DC Rapid Charging and Home Charging

The Leapmotor B03 supports DC rapid charging at up to 133 kW. Under the manufacturer’s stated conditions, charging from 10% to 80% takes approximately 21 minutes. A charge from 30% to 80% can take around 16 minutes.

For home charging, the vehicle supports 7.4 kW AC charging. Leapmotor quotes approximately seven hours and 15 minutes for a full charge from empty, making overnight charging a potential option for owners with suitable home charging equipment.

Charging times depend on battery temperature, charger capability, battery state of charge and other operating conditions. Peak charging power is not necessarily maintained throughout a charging session.

The B03 also supports vehicle-to-load (V2L) functionality through a 230-volt output. This allows compatible external electrical devices to draw power from the vehicle’s battery, adding utility for outdoor activities and situations where a conventional power supply is unavailable.

Cell-to-Chassis 2.0 Plus Architecture

The B03 is built around Leapmotor’s Cell-to-Chassis 2.0 Plus architecture, which integrates the battery into the vehicle structure rather than treating it as an entirely separate component.

The approach is designed to improve packaging efficiency and make more cabin space available within the car’s compact exterior dimensions. Leapmotor also says the integrated structure improves torsional rigidity, which can contribute to vehicle stability and handling.

The architecture works with the LEAP3.5 technology platform, which integrates vehicle hardware and software systems. In a small electric hatchback, these engineering choices are particularly relevant because efficient packaging can help balance passenger accommodation, battery capacity and cargo space.

Driver Assistance and Safety Equipment

Leapmotor says the B03 includes 21 driver assistance systems as standard, supporting Level 2 assisted-driving functions. The package uses a combination of 14 sensors and cameras to monitor the surrounding environment.

Listed features include adaptive cruise control, lane centring control, lane keeping assist, front collision warning, rear collision warning, intelligent speed assistance, driver attention monitoring and front vehicle departure alerts.

Rear cross-traffic braking is designed to detect approaching traffic while reversing and apply the brakes when required. A door-opening warning system monitors for approaching vehicles, cyclists and pedestrians to help reduce the risk of opening a door into their path.

The B03 also incorporates Leapmotor Integrated Motion Control (LMC), a chassis-control system intended to help maintain stability in challenging driving conditions. The manufacturer says the system can respond to detected grip loss within 200 milliseconds and is designed to help the vehicle maintain its trajectory during emergency manoeuvres.

Passive safety equipment includes seven airbags, including a centre airbag, as well as advanced seatbelt systems and automatic door unlocking following a collision.

Level 2 driver assistance does not make the B03 an autonomous vehicle. Drivers must remain attentive, supervise the system and retain responsibility for controlling the car.

Digital Connectivity and Keyless Access

The B03 combines its infotainment system with connected access features designed to simplify everyday use.

The Leapmotor smartphone app and Bluetooth connectivity support automatic unlocking as the driver approaches and locking when moving away. A physical key also provides keyless entry and starting, replacing the NFC card used on some other Leapmotor models.

Inside the vehicle, LEAP OS 4.0 Plus brings compatible applications, vehicle settings and digital functions together through the central touchscreen. The interface is designed to make commonly used features accessible without relying entirely on physical controls.

The availability of individual connectivity functions may depend on market specifications and the final production configuration.
