The ZHP was originally referred to simply as the “330i Performance Package,” but its code for ordering and information purposes was “ZHP,” and the title ended up sticking. A promotional brochure introducing the ZHP for the 2003 model year stated not many would be produced, with 1,000 6-speed transmission models and 3,000 automatic transmission models planned for production.
At its introduction for the 2003 model year, the ZHP gave some slight boosts to the BMW 330i’s performance potential, adding about 10 horsepower and eight pounds-feet of torque. It also had a speed limiter that extended to 155 miles per hour, compared to the standard 128.
