With its innovative design, B58 engine technology sets a new standard in luxury performance sedans. Experience the perfect fusion of power, refinement, and engineering excellence—ready to elevate your drive today. Discover the B58’s potential and drive the future of BMW performance.

The BMW B58 is a turbocharged straight-six engine, which began production in 2015. [1] The B58 replaced the N55 and was launched in the F30 340i. [2] The B58 is part of BMW's modular engine family, each engine using a displacement of 500 cc (30.5 cu in) per cylinder, following the B38 and B48 engine.

[3] The B58 engine was named to Ward's World's 10 Best Engines five times, in 2016 (installed. BMW's B58 turbocharged inline-six powers 41 models across BMW, Toyota, Morgan, and Ineos. A 2025 update adds more power, torque, and efficiency.

The B58 engine's displacement is 3.0 liters, with power outputs varying based on application. Its engine architecture is meticulously crafted to support high-performance capabilities while ensuring efficiency. Development History and Design Philosophy The genesis of the B58 engine was driven by BMW's ambition to forge high-performance, efficient powertrains.

The B58 3.0-liter single-turbo straight-six in the Supra and so many other BMW models is a legend in its own time.

A more than worthy successor to the 2JZ, and one of the best engines on sale today. When it comes to BMW's golden era of engines, enthusiasts often look back at the E46 M3's straight-six or the E39 M5's V8. But in the modern age, two names stand out: the B58 and its hardcore sibling, the S58.

These powerplants aren't just lumps of metal under the bonnet - they're the backbone of BMW's performance identity today. 🔥 From humble beginnings in 2015 with the B58. Closed Deck Design Let's first take a look at B58's closed deck design.

By nature, closed deck cylinder block is much stronger than the open deck type, therefore it is more suitable for high load and high pressure application. This explains why for the S55 engine (used on M3/M4), BMW needs to convert the N55's open deck block to a closed deck design. This is also the reason why BMW never.

The BMW B58 engine has earned a stellar reputation among automotive enthusiasts and industry professionals alike for its remarkable combination of performance, efficiency, and reliability. Launched in 2015 as part of BMW's modular engine family, the B58 is a 3.0-liter, inline. The B58 engine is celebrated for its advanced engineering and innovative design, which contribute to its superior performance and efficiency.

Modular Engine Family: The B58 is part of BMW's modular engine family, sharing components with the B38 and B48 engines. This modularity enhances production efficiency and ensures a high level of reliability across the range. All.

The engine's design also incorporates advanced technologies such as direct fuel injection and variable valve timing, which contribute to its impressive power output while maintaining fuel efficiency.
