With the same 53 kWh battery, the new Leapmotor B03 promises 8 km more range than the related B03X crossover. At the Paris Motor Show on October 12, the Chinese brand revealed the European specifications of the compact electric hatchback: up to 390 km WLTP, a 145 kW motor, or about 197 PS, and a 10–80% charge in 21 minutes.

Known in China as the A05, the model uses front-wheel drive. According to Leapmotor and Autocar, 0–100 km/h takes 7.6 seconds and peak DC charging power reaches 133 kW. With a body length of 4,175 mm and a width of 1,790 mm, its turning circle is just 9.8 metres, a useful figure for tight city streets.

The B03 is not only about its electric hardware. The boot holds 405 litres, while a separate 90-litre Leap Box sits under the floor. The front passenger seat can fold for long items, and the rear-seat cushions lift to free space for taller cargo. The cabin has around 30 storage compartments.

The driver gets an 8.8-inch digital instrument display and a 14.6-inch central touchscreen running Leap OS 4.0 Plus. Wireless Apple CarPlay and Android Auto are supported. Leapmotor also lists 21 driver-assistance systems, heated front seats and a heated steering wheel.

The comparison with the B03X is also notable. The related electric crossover in ProMax trim with the same 53 kWh battery is rated at up to 382 km WLTP. The new hatchback reaches up to 390 km. The difference is only 8 km, but the B03 still delivers slightly more certified range without a larger battery.

In July, the European Leapmotor B03 was still being judged mostly from preliminary data. The manufacturer has now released specifications for the more powerful European version. UK sales are due to begin in early 2027, with the car expected in a single high-spec trim. Autocar expects a starting price below £25,000, but Leapmotor has not yet published the final price.

Leapmotor is also expanding European production. After pre-series vehicles, the company announced on October 12 that production of the electric B10 had begun at the Stellantis plant in Zaragoza. That does not confirm where the B03 itself will be built. The next important step will be publication of prices and the final European trim structure.
