The BMW 320Ci was a variant of the E46 3 Series that was introduced for the 1999 model year. The 320Ci was offered in a Coupe or Convertible body style, and was initially powered by BMW's 145hp M52TUB20 2.0L turbocharged inline six engine. This engine was replaced for the 2001 model year by the 168hp M54B22 2.2L naturally aspirated inline six. Engines on the 320Ci were paired to manual and automatic transmission options sending drive to the rear wheels. Production of the E46 320Ci lasted until 2006, when BMW introduced the next generation E90 3 Series.
