The CM Persona is based on an extended Proton GEN•2 platform, and was sold as a saloon complement to the GEN•2 hatchback.

It was pitched as a premium version of the existing Proton Persona with exclusive kit and luxury equipment.

The Campro IAFM engine's power output remains unchanged, but was upgraded with a completely new 32 bit ECU from Continental's VDO division.

After the launch of the Proton Prevé, the Persona lineup was reduced to a sole Standard variant which was effectively the B-Line model.

Like the Saga SV, some trim and equipment were removed in an effort to lower its pricing, but Proton did not compromise on safety as the Persona SV is equipped with dual front airbags, front seat belt pre-tensioners and all-round disc brakes with ABS and EBD.

Such safety equipment is comparable to its main competitors, the Toyota Vios, Honda City and Nissan Almera.

The 1.6-litre CamPro S4PH engine in the CM Persona is the same 82 kW (110 hp) unit used in other Proton models, but with an improved cast aluminium oil pan design that reduces potential damage risks.
