What Engine Powers the BMW Z4 and Key Performance Details
The BMW Z4 delivers exhilarating performance wrapped in sleek design, and its heart lies in a precision-engineered powertrain that balances efficiency and power—each variation offers a unique driving experience shaped by its engine configuration.
Engine Variants in the BMW Z4 The 2024 BMW Z4 is equipped with two primary engine options: the turbocharged inline-six (3.0-liter B58) in the Z4 M40i, delivering 382 horsepower with seamless torque, and a naturally aspirated 2.0-liter inline-four (B48) in the Z4 30i, offering a refined 255 horsepower with responsive throttle response. These engines are engineered for dynamic handling and driver engagement, with the M40i variant featuring advanced variable valve timing and twin-scroll turbocharging for enhanced efficiency and performance.
The B58 inline-six in the M40i powers the Z4 with a balance of raw power and smoothness, supported by a six-speed automatic transmission that optimizes gear shifts for both track and daily driving. The B48 naturally aspirated engine prioritizes driver connection, providing a purer, more engaging driving experience ideal for enthusiasts who value performance purity over sheer output.
Together, these engines reflect BMW’s commitment to dynamic versatility, ensuring the Z4 excels across diverse driving conditions—from spirited coastal roads to spirited track sessions.

The turbocharged B58 engine benefits from direct injection and precision fuel delivery, while the naturally aspirated B48 leverages BMW’s valve timing innovations for optimal airflow and responsiveness. These engineering choices position the Z4 among BMW’s leading sports coupes, offering a compelling blend of performance, refinement, and driver focus.
