320d

320d is a model designation used by BMW for the 3 Series when fitted with a 2.0-liter four-cylinder turbocharged diesel engine. The badge has been used across several generations and body styles, including sedans, wagons, and sometimes hatchbacks, in markets around the world. The 320d line is typically chosen for its balance of practicality, torque, and fuel efficiency.

Generation history: The 320d first appeared in the early 2000s within the E46 3 Series family, using a 2.0-liter diesel engine. In later generations, BMW transitioned to newer turbo-diesel units (such as the N47 and then the B47) while keeping the 320d badge for models with roughly that displacement. The 320d has been offered with rear-wheel drive as standard, with all-wheel drive (xDrive) available on many variants.

Performance and options: Across generations, the 320d typically produces about 150 to 190 horsepower, with peak torque commonly in the 320 to 400 Newton-meter range depending on model year and market. Transmission choices have included six-speed manuals and eight-speed automatics, with different drive configurations available, including xDrive in many markets. Fuel economy and emissions improved with newer versions as part of BMW’s efficiency programs.

Market position: The 320d has been marketed as a practical, fuel-efficient option within the 3 Series, providing reliable daily usability with adequate performance for highway driving. It coexists with higher-performance diesel variants in some markets but remains a common entry point for a diesel-equipped 3 Series.
