The M4 2015 is powered by the BMW B58 inline-6 engine, code-name BMW M4B58. This naturally aspirated 3.0-liter six-cylinder produces between 425 and 450 horsepower depending on the variant—M40i delivering 425 hp, M4 Competition with 450 hp. Known for its balanced power delivery and high-revving nature, the B58 engine integrates direct injection, variable valve timing, and a lightweight aluminum block for optimal efficiency and responsiveness.

The B58 engine features a 90-degree inline configuration with dual overhead camshafts and a 3.0L displacement. It achieves a 12.3:1 compression ratio, supporting direct fuel injection and high-performance driving. The M4 variants include advanced cooling, upgraded intercoolers, and performance-tuned ECUs to handle sustained high loads. Under the hood, the engine manages heat efficiently, ensuring reliability during track use or daily driving.

Regular oil changes, coolant checks, and air filter replacements preserve engine health. For optimal performance, consider upgrading to performance exhaust systems and high-flow fuel injectors. Always use manufacturer-recommended lubricants and adhere to scheduled maintenance to maximize power output and longevity. Monitoring driving patterns and avoiding excessive boost or revs helps sustain engine durability over time.
