The 2007-2011 BMW 123d 5-door Hatchback is a premium compact car known for its powerful twin-turbo four-cylinder diesel engine. It was lauded for its exceptional balance of dynamics and fuel economy (EfficientDynamics), leading its class in performance and efficiency, and was the first all-aluminum diesel engine of its kind. Enthusiasts praised the "willing engine" that revs uncharacteristically high for a diesel, offering fun-to-drive qualities. However, it is infamous for the potential timing chain issues associated with the N47 engine. The 123d is well-suited for drivers seeking a quick, rear-wheel-drive hatchback that delivers performance without sacrificing fuel efficiency in daily driving and highway cruising.
The 2007-2011 BMW 123d running costs include fuel, depreciation, and repair costs, averaging around 44.95–63.70 ppm. Be cautious of the N47 engine, which is notorious for timing chain issues. Insurance costs average $102–$151 per month.
