Codenamed "C52X" during its development, it was first teased in 10 November 2021 under the placeholder name "Beijing X6", with its official name was determined by a public voting campaign ran by BAIC.

[6] A pre-production prototype was unveiled in 11 November 2021 during the 2021 Guangzhou International Motor Show, subsequently revealing Mofang as its official name.

In some countries' marketing materials, the model is simply referred as the BAIC X55, omitting the Beijing sub-brand nomenclature, but regardless, the X55 retain the physical 'BEIJING' emblems.

The engine is rated at 130 kW (177 PS; 174 hp) and 305 N⋅m (31.1 kg⋅m; 225 lb⋅ft) of torque, and is mated with a 7-speed dual-clutch transmission (DCT).

[15] The updated version, bearing with the additional Plus moniker, was revealed in August 2024 at the 2024 Kyalami Festival of Motoring,[16] and went on sale in September 2024.

[23] Initially imported from China, the vehicle will be locally assembled at Handal Indonesia Motor's new second facility in Purwakarta, West Java.

Three examples of the vehicle were first showcased in October 2023 during the ground-breaking ceremony event of EP Manufacturing's Melaka facility, initially referred as the X55 II.

It was introduced in March 2024, alongside the B40 Ragnar, B60 Beaumont, B80 Wagon and X7 Grandeza, coinciding with the re-launch of the BAIC brand in the country for the second time, following its distribution acquisition by the local distributor United Asia Automotive Group Inc.

[34] Unlike other markets, alongside the conventional petrol, the Cirelli 4 features an option of a bi-fuel (petrol/LPG) setup.
