A prime example of BMW's contemporary approach to performance engineering is the 3.0-liter turbocharged inline-six BMW
B58 engine. Designed to comply with more stringent emissions and efficiency standards while maintaining the smoothness and driving character typically associated with BMW's inline-six engines, it was introduced as the N55's replacement. The B58 was designed to be a member of BMW's modular engine family from the start, which allowed for increased production efficiency, scalability, and uniformity.
