- BMW introduced the E30-generation 3 Series in the United States late in the 1983 model year. The model was initially offered only with two doors, but the range grew with the addition of a four-door model in 1985 and a convertible in 1987. BMW E30s were available with 4-cylinder and 6-cylinder engines in the United States.
- Power comes from a 2.8-liter M52 inline-6, rated at 190 horsepower and 206 lb-ft of torque in stock form and application. Due to the modifications performed on this BMW, it may produce more power, but a dyno sheet was not provided to confirm. Output is sent to the rear wheels via a 5-speed manual transmission.
