Near the end of E46 3 Series production, BMW introduced the Performance Package (ZHP). The 330i ZHP sedan was introduced for the 2003 model year and was built until 2005. Featuring a tuned engine, as well as modified suspension, ZHP cars were more capable dynamically than their standard counterparts, as well as featuring subtle aesthetic tweaks to help differentiate the models. A two door version, the 330ci ZHP was also introduced in 2004. Production of the 330i ZHP ended in 2005, with a total of 6,569 examples built.
