The BMW 324d was a diesel variant of the E30 BMW 3 Series that debuted for the 1985 model year. The 324d was the first diesel powered offering from BMW, offered exclusively as a sedan and featuring the company's M21D24 engine. This 2.4L inline six was a naturally aspirated diesel powerplant that generated 84hp. BMW would later introduce a turbocharged version of the 324d known as the E30 324td. Production of the BMW 324d lasted until 1991, when the model series was discontinued.
