Near the end of E46 3 Series production, BMW introduced the Performance Package (ZHP) which was available in North America for the 330i and the 330Ci. The 330Ci ZHP was available as a coupe or convertible, and was introduced for the 2004 model year. Featuring a more powerful 3.0L inline six engine as well as modified suspension, ZHP cars were more dynamically capable than their standard counterparts. These ZHP cars featured subtle aesthetic tweaks that helped differentiate the models. The 330Ci ZHP was built in four main variants, Coupe - Manual, Coupe - Automatic, Convertible - Manual, and Convertible - Automatic. A sedan version, the 330i ZHP, was also offered.
